ELECTRONIC RACING GAME
Abstract
A method and system for racing a plurality of motor driven units
along a track which combines a random factor, not subject to
control, with manually actuated means for establishing odds between
the racing units at the beginning of each race. In a preferred
embodiment, the heart of the system comprises two pulse sources
operating at substantially different nonharmonic frequencies which
are characterized by built-in frequency drifts. The higher
frequency pulse source drives a system of stepping selectors
through a repetitive cycle. The initial manual arrangement of a
group of odds selector dials determines the number of times a power
circuit is completed to any specific racing unit as the stepping
system proceeds through its cycle. At random contacts during the
stepping cycle, depending on the operation of the second pulse
source, electrical current passes through one of the power circuits
momentarily completed, to drive one or another of the racing units
to spurt ahead. This continues until one or more of the units cross
an arbitrary finish line. In a preferred embodiment, the racing
units are motor driven horses. The odds manually set on each of the
horses at the beginning of the race are also indicated on an
electronic tote board, which is electronically triggered to
indicate Win, Place and Show, at the end of each race, and also,
the amount paid on each of the winning horses. Additional features
include means for setting and counting races of more than one
lap.

Description
BACKGROUND OF THE INVENTION
This invention relates in general to electronic methods and
apparatus for random selection, and more specifically, to
electronically controlled races, specifically simulated horse
races, operating at preselected odds.
Horse racing and various other games of chance rely on the
unpredictability of the result to attract the interest and bets of
participants. In attempting to simulate the chance factor of an
actual race, various means have been employed, such as the spinning
of a wheel, the throwing of dice, etc. Such means are, at best,
crude, and, at worst, lend themselves to patterned repetition which
is predictable, and which can be dishonestly manipulated by the
operator and others. Furthermore, such methods of chance selection
cannot be combined readily with the preselective setting of odds
for individual racing units, which is a salient feature of an
actual horse race.
Accordingly, it is a general object of this invention to provide a
method and apparatus for random selection of contest winners which
is highly unpredictable, and not readily subject to patterned
repetition or manipulation. A more specific object of the invention
is to provide an electronic racing game in which the racing units
can be operated at preselected odds, but without the winner being
predictable, and more particularly, one which closely simulates by
electronic means the random factors, together with techniques for
preselecting odds, which combine to generate interest and betting
on horse races.
SUMMARY OF THE INVENTION
These and other objects and features are attained in the present
invention by operating a pair of pulse actuated timing sources at
two substantially different nonharmonic frequencies, each subject
to a slight frequency drift, to control a plurality of racing units
by means of a complex system of stepping selectors which move
through a repetitive cycle of steps. Random bursts of power for
moving one or another of the racing units forward are derived
whenever there is a coincidence between the pulses of the two
timing sources. Each of the racing units may have associated with
it a switch which, at the onset of the race, can be positioned to
vary the odds between the respective racing units by changing the
number of steps during the stepping cycle at which a specific unit
is connected to receive the random bursts of power.
The illustrative embodiment under description takes the form of an
electronic horse race having six motor driven horses, each of which
moves on an individual pair of conducting rails around an oval race
track. For the sake of simplicity, circuits relating to only three
of the horses are described. It will be understood that the
principle of the invention can be applied to systems having a
larger number or smaller number of horse units. In the system under
description, each horse unit has an associated dial, by which its
individual odds can be preset between one-to-one and 10-to-one, at
the beginning of each game. Adjacent the finish line is a tote
board which lights up to show the odds on each horse and which also
lights up to indicate instantaneously, as they cross the finish
line, which of the horses are in the Win, Place and Show positions,
and the money payable to the bettors on each. Additional circuits
are included which provide for the possibility of multiple laps
around the track, and means for indicating the results of the
multilap races on the tote board.
These and other objects, features and advantages will be apparent
to those skilled in the art, upon a detailed study of the present
invention in connection with the attached drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
PRELIMINARY DESCRIPTION
To simplify the description of the complex circuitry of the present
illustrative embodiment, the circuit has been divided into eight
Circuit Boards, each designated by an identifying capital letter
and a specific Figure number, as indicated in FIG. 12 of the
drawings. To clarify reference characters, a separate set of
numbers is used on each Circuit Board. When tracing circuits which
lead from one Circuit Board to another, the reference number is
preceded by a capital letter, indicating the Circuit Board, as
"W180," although the identifying letter is omitted when it is clear
that the cited reference numerals are on the same Circuit
Board.
In the embodiment under description, the game consists of six motor
driven plastic horses; but it can be modified to accommodate a
greater or lesser number, all disposed on an eight foot by four
foot, six lane, two rail oval track. Each horse has a selector
switch associated with him which can vary his odds from one-to-one
to 10-to-one. (This can also be modified to accommodate greater
odds.) The greater the odds on the horse the less chance he has to
win; but he nevertheless has some chance to win. The odds for each
horse light up on a tote board at the time they are selected prior
to the race. When the race is started, the horses race in short
bursts of speed around the track until they reach the finish line.
Upon crossing the finish line, the first three horses automatically
light up their numbers on the tote board in their respective order
of finish, Win, Place and Show. The prices associated with the odds
of these three horses also light up automatically for Win, Place
and Show. The third horse to cross the finish line also turns the
game off; but the numbers and prices remain lighted on the tote
board until the tote board reset switch is activated.
OVERALL ARRANGEMENT
FIG. 1 of the drawings is a perspective showing of three horses
crossing the finish line in the electronic racing game in
accordance with a described embodiment of the present invention,
with the electronically actuated tote board in the background,
showing the selected odds, indicating which of the horses is in
Win, Place and Show position, and the winning money to be paid on
each.
In the embodiment under description, as actually constructed, there
are six separate pairs of tracks, one pair for each of the six
horses in the race. The two tracks forming each pair, which are
spaced five-eighths inch apart, are formed of highly conductive,
durable metal, each track having a highly polished, low friction
upper surface designed to provide substantially uniform electrical
contact with the slidably engaging lateral contact members on the
two ends of an individual horse circuit of the form shown in FIG.
2. In the present embodiment, the outermost track (Horse No. 6)
forms an external oval about four feet by eight feet, with the
innermost track (Horse No. 1) defining an oval about three and
one-fourth feet by seven and one-fourth feet. It will be apparent
that in the alternative a single, bar rail could be substituted for
the two rail track described with reference to the present
embodiment.
HORSE MOTOR CIRCUITS
Referring to FIG. 2 of the drawings, there is shown in schematic
the driving circuit which fits under each of the plastic shells for
Horses No. 1 through No. 6 to drive each horse along its specific
lane of the track. Each of the circuits includes a small
alternating current motor 2a of conventional design, which, for
example, may be operated with 0.004 to 0.006 horsepower, drawing
one-quarter ampere current, at 10-20 volts. The motor 2a is shorted
across by a conventional diode 2b. The latter permits current for
the Tote Board Relays (shown in Circuit Board Z, FIGS 9A, 9B) to
by-pass the motor 2a, while blocking the motor current, forcing it
to pass through and run the horse, as will be described
hereinafter.
THE TRACK AND CONNECTIONS
Referring now to FIG. 3 (Circuit Board Y), there is shown, as
formed in the present illustrative embodiment, six track lanes. For
convenience of description hereinafter, the circuits relating to
Horses No. 1, No. 2 and No. 6 are described in detail, whereas the
circuits relating to Horses No. 3, No. 4 and No. 5 have been
omitted in order to simplify the description and reduce
repetition.
The track sections indicated in FIG. 3 (Circuit Board Y) include
the Finish Line Connections, the Lap Counter Connections and the
Power Connections Sections 3a, 3b and 3c, containing the Finish
Line Connections, and sections 3d, 3e and 3f, containing the Lap
Counter Connections, are each insulated from the other sections of
track in each of the lanes so that they do not receive any power
from or through the track.
In section 3a (Horse Lane No. 1) the finish line contacts 1 and 2
are respectively connected to contacts Z171 and Z189 on Circuit
Board Z (FIGS. 9A, 9B); in section 3b (Horse Lane No. 2) the finish
line contacts 3 and 4 are respectively connected to contacts Z172
and Z190; and in section 3c (Horse Lane No. 6) the finish line
contacts 11 and 12 are respectively connected to contacts Z176 and
Z194. On Circuit Board Z these contacts lead through terminal strip
9p to an appropriate dial on the ganged Lap Counter Switches of
Circuit Board S (FIGS. 7A, 7B), ultimately passing through the
contacts of the Lap Counter Relays on Circuit Board T (FIG. 8), as
will be described hereinafter.
Returning to FIG. 3, the purpose of the Lap Counter Connections
indicated in sections 3d, 3e and 3f, for Horse Lanes No. 1, No. 2
and No. 6, respectively, is to provide contacts through the
appropriate ganged dials of Circuit Board S (FIGS. 7A, 7B), so that
if the operator desires to set the game up for more than one lap,
the proper relays will be actuated to carry the horses through the
finish line sections on the first lap around without actuating the
Win, Place and Show indications on the tote board, the showing of
which is deferred until the last lap. The Lap Counter Connections
include contacts 13 and 14 on section 3d (Horse Lane No. 1) which
are respectively connected to contacts T101 and T100 on the
terminal strip 8h of Circuit Board T. Likewise, on section 3e
(Horse Lane No. 2) lap counter connections 15 and 16 respectively
lead to contacts T103 and T102; and in section 3f (Horse Lane No.
6) lap counter connections 23 and 24 respectively lead to contacts
T111 and T110. The T connections all lead through the contacts and
to the energizing circuits of the Lap Counter Relays which will be
described in detail hereinafter with reference to Circuit Board
T.
The Power Connections in each of the lanes lead to the power
circuits for each of the specific horses which are shown on Circuit
Board V (FIG. 6). These power circuits function to energize the
motor 2a (FIG. 2) in each of the horses, driving a specific horse
forward along its track lane. In section 3g (Lane No. 1) power
contacts 25 and 26 are respectively connected to contacts V74 and
V75 on terminal strip 6a of Circuit Board V (FIG. 6). Likewise, in
section 3h (Lane No. 2) power contacts 27 and 28 are respectively
connected to contacts V71 and V72 on terminal strip 6b; and in
section 3i (Lane No. 6) power contacts 35 and 36 are respectively
connected to contacts V59 and V60 on terminal strip 6c. On Circuit
Board V, the foregoing contacts lead through switches to the
rheostats controlling the speed on each of the individual horses
and through the normally open contacts of the horsepower relays,
the operation of which will be described hereinafter.
PULSE TIMING AND SELECTOR SYSTEMS
We will now pass from the track sections to a description of the
complex electrical circuit which drives the individual racing
horses along the track. The heart of this system is shown in detail
in FIGS. 4A, 4B which are combined as indicated to form Circuit
Board W. This shows the master start-stop switches of the circuit,
plus the pulse operated timing circuits, one of which drives a
stepping selector system which operates respectively through a
total of 48 contacts.
Referring to FIGS. 4A, 4B (combined to form Circuit Board W), there
are shown three double-pole manually operated switches 4h, 4p and
4q, which put the set in operating condition. In the tote board
reset switch 4h, contact 180 is connected in Circuit Board T (FIG.
8) to one terminal T1 of the 12 volt, 2 ampere rectifier 8a which
supplies power for the Lap Counter Relays. Contact 182 is connected
to contact Z3, one terminal of the 6.3 volt, 1.2 ampere rectifier
9aa on Circuit Board Z (FIGS. 9A, 9B). When switch 4h is in "off"
position, power from these sources to the set is cut off. When this
switch is in "on" position, power connections are respectively made
between contacts 180 and 179, and between contacts 182 and 181.
Contact 179 leads to normally closed contacts T5 of lap counter
relays 8b, 8c and 8d (Circuit Board T, FIG. 8), and to normally
open contacts T4 of lap counter relays 8e, 8f and 8g. The operation
of the lap counter circuits will be described in detail
hereinafter. Contact 181 leads to the normally open contacts Z5
(Circuit Board Z, FIGS. 9A, 9B) of the Win, Place and Show
relays.
In switch 4p, contact 184 is connected to contact W112 of the 24
volt, 1 ampere rectifier 4bb for supplying power to stepping
selectors 4a and 4b; and contact 186 is connected to contact W110
of rectifier 4cc for supplying power to stepping selectors 4c, 4d,
4e and 4f. In "off" position, these contacts are open; whereas, in
"on" position, contact 184 is connected to contact 183; and contact
186 is connected to contact 185. Contact 183 leads through the
normally open contact W160 of relay 4i of the First Timer, which
closes periodically when the latter is energized. Contact 160 leads
in parallel through energizing coils of relays 4a and 4b of the
Primary Stepping Selectors. Thus, when coil 4i of the First Timer
is actuated, current will pass from rectifier 4bb to simultaneously
step both of the primary stepping selectors 4a and 4b.
Contact 185 leads to contact W147 of the terminal strip 4dd, which
is ultimately connected to the selector arm W138 of stepping
selector relay 4a. Thus, when the switch 4p is closed, power is
provided through selector arm 138 and through whichever contact it
rests on at the time, to energize the corresponding auxiliary
selector 4c, 4d, 4e or 4f, causing it to move through a single step
at the beginning of the race. This will break up the formation of
any repetitive pattern of operation from one race to the next.
In switch 4q, contact 190 is connected to contact W176 of the 6
volt, 1.2 ampere rectifier 4m, which supplies current for the First
Timer and the Second Timer. When this switch is in an "on"
position, current passes from rectifier 4m through contact 189
which leads through the normally closed contacts Z146 and Z145 of
the cut-off relay 9m shown on Circuit Board Z (FIGS. 9A, 9B). This
circuit is connected to both the normally closed and normally open
contacts W157 and W163 of relays 4i and 4j of the First Timer, each
of which is interconnected with the energizing circuit of the
opposite relay. Also, the circuit through the normally closed
contacts Z146 and Z145 of the cut-off Relay (Circuit Board Z) is
connected both to the normally closed and normally open contacts
W167 and W174 of relays 4k and 4l of the Second Timer (Circuit
Board W, FIGS. 4A, 4B), each of these contacts being connected
through the energizing circuit of the opposite coil. The return
circuit passes from contacts W156 and W162 at the ends of the relay
coils 4i and 4j, to contact W175 at the other pole of rectifier 4m.
Thus, when the switch 4q is closed, the relay coils 4i and 4j of
the First Timer and 4k and 4l of the Second Timer are energized and
deenergized in tandem relation in each Timer, at pulse rates which
are controlled in each case by the size of the condensers across
each of the respective coils.
In the First Timer, a 45 microfarad condenser is connected between
points 156 and 155 across the energizing coil of relay 4i; and a 75
microfarad condenser is connected between points 162 and 161 across
the energizing coil of relay 4j. In operation, the First Timer
produces a mark pulse of one-half second, and a space pulse of
slightly less than one-half second, pulsing at a rate of 68 to 70
pulses per minute.
In the Second Timer, a 115 microfarad condenser is connected
between contacts 166 and 165, across the energizing coil of relay
4k; and a 150 microfarad condenser is connected between points 172
and 171 across the energizing coil of relay 4l.
In operation, the Second Timer produces a mark pulse of one-half
second, and a space pulse of one second, and pulses at a rate of 38
to 40 pulses per minute.
A most important feature of each of the pulse Timers is that the
pulse rates are nonharmonic, and each of the pulse sources has a
built-in frequency drift, whereby the frequency of each varies one
or two beats per second. This increases the randomness of the
operation.
It will be understood that in place of the First Timer and the
Second Timer, of the form indicated, there can be substituted other
types of pulsing circuits, of forms well known in the art, such as,
for example, multivibrator circuits, adjusted to produce pulses of
the desired pulse widths and relative frequencies, and each
including a built-in drift of one or two beats per second as in the
present system.
Whenever coil 4i of the First Timer is energized, closing contacts
159 and 160, a power circuit is completed from contact W112 of
rectifier 4bb, supplying 24 volt, 1 ampere current, through switch
4p to W contacts 142 and 139 which are respectively connected to
the parallel energizing circuits of primary stepping selector
relays 4a and 4b, driving each of them to step in concert through a
repetitive cycle of 12 contacts each. Primary stepping selector 4a
steps through its contacts 113 through 124, making contact by means
of selector arm 138. Second primary stepping selector 4b steps
through its contacts 125 through 136, making contact by means of
selector arm 141. The stepping selector 4a is, in turn, connected
to energize and cause to step, in sequence, four additional
stepping selectors 4c, 4d, 4e and 4f, of 12 contacts each, as will
be explained with reference to FIG. 4B.
The two selector coils of 4a and 4b are connected in parallel,
contact 139 being connected to contact 142 at one end of the two
coils, and contact 137 being connected to contact 140 at the other
coil terminals. The common connection from contact 137 is connected
to contact 111 of rectifier 4bb to supply 24 volt, 1 ampere current
to the Stepping Selectors. Each of the selector coils 4a and 4b is
shorted by a 0.25 microfarad condenser. The stepping selectors 4a
and 4b respectively have selector arms 138 and 141. Stepping
selector arm 138 is connected to contact W147 on the terminal strip
4dd, which leads through the switch 4p back to contact W110 of
rectifier 4cc, when the switch is closed, supplying 24 volt, 1
ampere current to drive the stepping selectors 4c, 4d, 4e and 4f,
as will be explained. The stepping selector arm 141 is connected to
contact W169 of the Second Timer, the function of which connection
will be explained presently.
Contacts 113 through 124 of primary selector 4a are interconnected
together in groups of four, so that 113 through 116 are
respectively connected to 117 through 120; and the latter group of
four is respectively connected to contacts 121 through 124.
Contacts 121 through 124 are respectively connected, in order, to
four W contacts 143 through 146, along the terminal strip 4dd.
The four auxiliary selectors 4c, 4d, 4e and 4f, which are operated
in sequence by the selector 4a, have each of their coils shorted
across by a 0.25 microfarad condenser. Selector coil 4c is
connected between contacts 99 and 97; selector coil 4d is connected
between contacts 102 and 100; selector coil 4e is connected between
contacts 105 and 103; and selector coil 4f is connected between
contacts 108 and 106. Contacts 99, 102, 105 and 108, at one end of
each of the aforesaid coils 4c, 4d, 4e and 4f, are respectively
connected to W contacts 143, 144, 145 and 146 on the terminal strip
4dd. The other terminals 97, 100, 103 and 106 of each of these
respective coils are all connected together to complete the circuit
to W contact 109 of rectifier 4cc. Thus, the four coils 4c, 4d, 4e
and 4f are energized to step in consecutive sequence, so that when
primary selectors 4a, 4b take four steps, each of the auxiliary
selectors takes one step in sequence.
Auxiliary stepping selector contacts 49 through 96 are respectively
connected, in numerical order, to W contacts 1 through 48 on
terminal strip 4n. These contacts are then combined by strapping
into sixteen groups, consisting of six groups of four contacts
each, four groups of three contacts each, and six groups of two
contacts each. Each of these groups is connected to a specific one
of contacts R289 through R304 on terminal strip 5a of Circuit Board
R (FIGS. 5A, 5B). These connections are indicated in Table I, which
follows.

the grouped contacts from the terminal strip 4n, arranged in the
manner indicated in Table I, are connected to terminal board 5a of
Circuit Board R (FIGS. 5A, 5B), which shows the Odds Selector Dials
which are set up to control the number of individual circuit wires
connected in succession to each of the horsepower circuits during a
specific selector cycle. This will be described presently.
Before passing to a description of Circuit Board R, let us return
to Circuit Board W (FIGS. 4A, 4B) for a description of the function
of the Second Pulse Timer, which in the present embodiment is
arranged to provide pulses at the rate of 38 to 40 pulses per
minute, as opposed to a pulsing rate of 68 to 70 pulses per minute
for the First Timer. As previously described, the latter energizes
the two primary stepping selector coils 4a and 4b to step through
their simultaneous cycle of twelve steps, operating to energize, in
tandem, coils 4c, 4d, 4e and 4f of the auxiliary stepping selectors
to control the sequential stepping of these selectors through their
steps 49-96.
Stepping selector coil 4b actuates selector arm 141 to step through
steps 125 through 136, while selector arm 138 of coil 4a is
stepping through steps 113 through 124. It will be apparent that
selector steps 125 through 136 are also connected in groups of
four, each of which groups is connected to a contact on terminal
strip 4dd. Thus, W contacts 125, 129 and 133 are connected to W
contact 149 on terminal strip 4dd; contacts 126, 130 and 134 to
terminal strip contact 150; contacts 127, 131 and 135 to terminal
strip contact 151; and contacts 128, 132 and 136 to terminal strip
contact 152. Each of the terminal strip contacts 149, 150, 151 and
152 is respectively connected through a diode to the respective
selector arms 98, 101, 104 and 107 of the four auxiliary selectors
4c, 4d, 4e and 4f.
It will be apparent that when relay coil 4k in the Second Timer is
energized, closing its contacts 169 and 170, a 6 volt, 2 ampere
current passes from contact 177 of the rectifier 4aa, through
selector arm 141, into one of the four selector arms 98, 101, 104
or 107 of the auxiliary selectors, and into one of the 48 contacts
49 through 96, depending upon which step the auxiliary selector has
reached at that moment.
This random shot of current passes through one of the 48 contacts
of terminal strip 4n, selected by pure chance, and into the
horsepower circuit of one of the horses on the track, causing it to
move forward. The number of times the driving circuit for any
specific horse will be in position to receive a shot of current
from the random pulse source, Second Timer, will be determined by
the manual arrangement of the Odds Selector Dials, which will now
be described with reference to Circuit Board R (FIGS. 5A, 5B).
ODDS SELECTOR SYSTEM
Referring now to Circuit Board R, there is shown a plurality of
manually operated rotary selector dials, each of which is equipped
with eleven contacts and a selector arm which is manually movable
in a clockwise direction from a null position, with no connection,
to engage any of the remaining positions which are connected in a
manner to set up the desired odds. The rotary selectors are
arranged in sections or gangs of four, one selector being assigned
to each of the horses running in the race. The selector arms of
each section of four are ganged together so that the four arms
simultaneously make contact at the same angular position on the
face of the dial. As seen, the dial contacts are numbered in order,
clockwise around the dials, reading from bottom to top of each of
the columns of dials.
In the illustration under description, detailed circuit
arrangements are indicated for the dial selectors connected to the
horsepower circuits No. 1, No. 2 and No. 6 (from left to right on
Circuit Board R, FIGS. 5A, 5B), the selector dial contacts for
horsepower circuits No. 3, No. 4 and No. 5 having been omitted in
order to simplify the description. It will be understood, however,
that the connections not shown will be substantially similar in
arrangement to those indicated with reference to Horses No. 1, No.
2 and No. 6.
Each of the selector dial arms shown on Circuit Board R is
respectively connected to a contact on the terminal strip 5a. For
example, ganged selector dial arms 305, 306, 307 and 308, relating
to Horse No. 1, are respectively connected to R contacts 265, 266,
267 and 268 on terminal strip 5a; ganged selector dial arms 309,
310, 311 and 312 relating to Horse No. 2 are respectively connected
to R contacts 269, 270, 271 and 272 on terminal strip 5a; selector
dial arms 325, 326, 327 and 328 relating to Horse No. 6 are
respectively connected to contacts 285, 286, 287 and 288 on
terminal strip 5a. It will be noted that each of the mentioned
contacts on terminal strip 5a has a diode connected between it and
the designated selector dial arms, to maintain unidirectional
current passing from the selector dial arm into the terminal
strip.
Contacts 265 through 268 on terminal strip 5a are connected
together to contact V76 on Circuit Board V (FIG. 6) leading to the
energizing circuit of the horsepower relay 6d of Horse No. 1, as
will be described later; contacts 269 through 272 on terminal strip
5a are connected together to contact V73 on Circuit Board V,
leading to the energizing circuit of the horsepower relay 6e of
Horse No. 2; and contacts 285 through 288 on terminal strip 5a are
connected together to contact V61 on Circuit Board V leading to the
energizing circuit of the horsepower relay 6f of Horse No. 6.
As indicated previously, the dial selectors for the Horse circuits
No. 3, No. 4 and No. 5 have been omitted; and likewise, the
intermediate connections on terminal strip 5a to the contacts 273
through 284 relating to these omitted horses have not been shown or
described, although it will be understood that they are
substantially similar to the circuits shown.
The contacts at the right-hand end on the lower side of terminal
strip 5a, numbered 289 through 304, lead from terminal strip 4n of
Circuit Board W (FIGS. 5A, 5B). These are grouped as indicated in
Table I hereinbefore, so that the first six contacts 289 through
294 are respectively connected to each of the six two-wire groups,
designated as 2.sub.6, 2.sub.5, 2.sub.4, 2.sub.3, 2.sub.2 and
2.sub.1, respectively; the next four contacts 295 through 298 are
connected to each of the four three-wire groups designated as
3.sub.4, 3.sub.3, 3.sub.2 and 3.sub.1, respectively; and the last
six contacts on the terminal strip, namely 299 through 304, are
connected in order to each of the six four-wire groups, designated
as 4.sub.6, 4.sub.5, 4.sub.4, 4.sub.3, 4.sub.2 and 4.sub.1,
respectively.
In order to better understand the theory behind the operation of
the odds selectors, one is referred to Table II. It will be
understood that although in Table II specific numerical odds have
been assigned to the wire total for each cycle, a particular wire
total can readily be adjusted on the tote board to produce a higher
or lower percentage of wining favorites at any given odds.

7-1 6 4 6 8-1 4 2 5 9-1 1,2 4 10-1
This Table includes a section for each of the horses under
description (No. 1, No. 2 and No. 6), showing, in each case, how
the grouped contacts from the right-hand end of terminal strip 5a
add up to a total which varies from 13, when the odds are
one-to-one, to four, when the odds are 10-to-one. The totals given
represent, in each case, the total number of contacts from terminal
strip 4n of Circuit Board W (FIGS. 4A, 4B), which are in a position
to receive power in each horse circuit during one complete cycle
through the 48 steps of selectors 4c, 4d, 4e and 4f.
As seen from Table II, when the odds selector dials relating to a
given horse circuit are put in the position of one-to-one odds, the
number of contacts in that specific horse circuit which are
positioned to receive power during one complete cycle of the
selector system add up to thirteen. As the selected odds are
progressively increased by setting the dials, the number of the
contacts positioned to receive power is progressively reduced to
twelve contacts, eleven contacts, ten contacts, etc., down to a
minimum of four, in the case of 10-to-one odds. The selector
contact arrangement is shown in Table III. ##SPC1## ##SPC2##
In order to make up these totals, as shown in Table III,
corresponding contacts on the four ganged odds selector dials
connected to each horse must be so chosen that they add up in each
case to the number indicated at Total Wires. For example, let us
refer to the ganged selector dials 5e, 5d, 5c and 5b which control
the odds selection for Horse No. 1. Contacts 34 on selector 5e, 23
on selector 5d, 12 on selector 5c and 1 on selector 5b, each
indicate the null or starting position. In order to indicate a
position of one-to-one odds (a total of 13 grouped contacts per
cycle), the four ganged selector arms of these dials are moved
clockwise one step. In this position the selector arm 308 of
selector dial 5e is positioned on contact 35; selector arm 307 of
dial 5d is positioned on contact 24; selector arm 306 of dial 5c is
positioned on contact 13; and selector arm 305 of dial 5b is
positioned on contact 2.
Tracing the circuits it will be seen that contact 35 is connected
to contact 292 on terminal strip 5a, which leads to the 2.sub.3
group of contacts. Contact 24 in odds selector dial 5d is connected
to contact 298 on terminal strip 5a, which corresponds to the
3.sub.1 contact group. In dial 5c contact 13 leads to contact 53 in
dial 5f; the latter, in turn, leads to contact 52 which leads to
contact 51, etc., around the dial, to contact 46, which is
ultimately connected to contact 303 on terminal strip 5a,
corresponding to the 4.sub.2 group. On dial 5b, contact 2 leads
directly to contact 304 on the terminal strip 5a, which corresponds
to contact group 4.sub.1. Thus, the grouped contacts 2.sub.3 plus
3.sub.1 plus 4.sub.2 plus 4.sub.1 add up to a total of 13.
In a similar way, as the four ganged selector arms are moved
through the next step in a clockwise direction, the contacts
engaged are 36 on dial 5e, 25 on dial 5d, 14 on dial 5c and 3 on
dial 5b. It will be seen by tracing the circuits that contact 36 is
ultimately connected to group 2.sub.1, 25 to group 3.sub.1, 14 to
group 3.sub.2 and 3 to group 4.sub.1 ; all of which add up to a
total of 12 contacts on terminal strip 4n of Circuit Board W.
Table III shows the contact arrangements of the odds selector dials
for each of Horses No. 1, No. 2 and No. 6, indicating the specific
contact groups of 2's, 3's and 4's corresponding to each of the
positions on the dials in clockwise succession, corresponding to
ascending odds. It will be understood that either electronically or
manually, the dials of FIGS. 7A, 7B (Circuit Board S) relating to
the tote board will be set up to correspond exactly to the selector
settings indicated in FIGS. 5A, 5B (Circuit Board R). The wiring of
the tote board dials (FIGS. 7A, 7B) will be described in detail at
a later point.
In the specific illustration under description, the following odds
have been selected and the dials set accordingly: Horse No. 1,
five-to-one; Horse No. 2, three-to-one; and Horse No. 6,
six-to-one. Thus, for Horse No. 1, ganged rotor arms 308, 307, 306
and 305 are respectively set on contacts 39, 28, 17 and 6, whose
wire total, as shown by Table III, is nine. For Horse No. 2, ganged
rotor arms 312, 311, 310 and 309 are respectively set on contacts
81, 70, 59 and 48, whose wire total, as shown by Table III, is 11.
For Horse No. 6, ganged rotor arms 328, 327, 326 and 325 are
respectively set on contacts 260, 249, 238 and 227, whose wire
total is shown by Table III, to be eight. This arrangement may be
varied at the beginning of each race.
HORSEPOWER CIRCUITS
The description will now pass to Circuit Board V (FIG. 6) which
details the power circuits for driving the individual horses on the
tracks. As indicated previously, the connections from the left-hand
end of terminal strip 5a (Circuit Board R, FIGS. 5A, 5B) consist of
connected groups of four contacts each, from the ganged selector
arms corresponding to each horse. These groups are respectively
connected to R contacts 268, 272 and 288, which are, in turn,
respectively connected to contacts V76, V73 and V61 on terminal
strips 6a, 6b and 6c (Circuit Board V).
Contact 76 on terminal strip 6a relating to Horse No. 1 is
connected to the energizing circuit of horsepower relay 6d through
contact 53. Likewise, contact 73 on terminal strip 6b is connected
to the energizing circuit of relay 6e through contact 49; and on
terminal strip 6c, contact 61 is connected to the energizing
circuit of relay 6f through contact 33. The energizing circuits of
horsepower relays 6d, 6e and 6f, relating to Horses No. 1, No. 2
and No. 6, respectively, are connected together in parallel
relation through contacts 34, 50 and 54. The latter is connected
through V contact 77 on terminal strip 6i to contact W178 of the 6
volt, 2 ampere rectifier 4aa on Circuit Board W (FIGS. 4A, 4B), as
described hereinbefore, which supplies current to energize each of
the relays 6d, 6e and 6f.
When each of these three relays is energized, it respectively
closes its normally open contacts completing the driving circuits
of the individual horses. Relay 6d closes contacts 55 and 56; relay
6e closes contacts 51 and 52; and relay 6f closes contacts 35 and
36. These relay contacts, when closed, complete the driving
circuits through the track to each of the individual horse motors
as follows.
Horses No. 1 and No. 2 both derive power from rectifier 6g whose
terminal 2 is connected in parallel to V terminals 10 and 14 on the
rheostat boards 6m and 6n, respectively.
For Horse No. 1, slider 12 of rheostat board 6m is connected
through closed contacts 55 and 56 of horsepower relay 6d, through
contact 75 on terminal strip 6a to track power contact Y26 on
Circuit Board Y (FIG. 3), which contacts one terminal of the motor
of Horse No. 1. The return from the other terminal of that motor
leads from track contact Y25, through contact 74 on Circuit Board V
(FIG. 6), contact 11 on rheostat board 6m, and back to terminal 1
of rectifier 6g.
For Horse No. 2, slider 16 of rheostat board 6n is connected
through the closed contacts 51 and 52 of horsepower relay 6e,
through V contact 72 on terminal strip 6b to track power contact
Y28 on Circuit Board Y (FIG. 3), which contacts one terminal of the
motor of Horse No. 2. The return from the other terminal of this
horse motor leads from track contact Y27 through V contact 71 of
terminal strip 6b, and contact 15 of rheostat board 6n to terminal
1 of the rectifier 6g.
In the case of Horse No. 6, power is supplied from rectifier 6h.
Terminal 6 of the latter is connected to V terminal 30 of rheostat
board 6p. The slider 32 of the latter is connected through the
closed contacts 35 and 36 of horsepower relay 6f through V contact
60 of terminal strip 6c to the contact Y36 on the track (Circuit
Board Y, FIG. 3), contacting one terminal of the motor of Horse No.
6. The return track contact Y35 from the other terminal is
connected through V contact 59 of terminal strip 6c, contacts 31
and 29 of rheostat board 6p, to the terminal 5 of rectifier 6h.
Manually actuated switches 6j, 6k and 6l respectively short the
contacts of relays 6d, 6e and 6f, permitting the horses to be
powered manually, when necessary. The speeds of the individual
Horses No. 1, No. 2 and No. 6 can be adjusted or calibrated at the
initial set up of the game by manipulating the sliders 12, 16 and
32 on the respective rheostats 6m, 6n and/or 6p. The purpose of
this is to permit the speed of the horses to be so regulated
initially that they complete the trip around the track in the same
time, absent odds and chance factors, notwithstanding the fact that
the outside track is slightly longer than the inside track. This
will be explained further, hereinafter, with reference to FIG.
11.
It will be apparent that, as in the descriptions of previous
figures, the contacts and circuits corresponding to Horses No. 3,
No. 4 and No. 5 have not been shown.
The rectifier 6q, which provides common power for the finish line
on the second lap, is connected through its contacts 7 and 8, which
respectively pass through contacts 57 and 58 of terminal strip 6aa,
to V terminals 80 and 81 (the slider) of rheostat board 6bb.
Terminals 78 and 79 of the latter are respectively connected to
terminals T6 and T7, common contacts of the Lap Counter Relays on
Circuit Board T (FIG. 8), which will be discussed hereinafter.
ROTARY TOTE BOARD SWITCHES AND TOTE BOARD CONNECTIONS
Prior to the race, when odds for each horse are selected on the
Odds Selectors of Circuit Board R (FIGS. 5A, 5B), the Win, Place
and Show switches of Circuit Board S, which are indicated in FIGS.
7A, 7B, must be dialed to exactly correspond, so that the
indications on the tote board (Circuit Board K, FIG. 10) show the
same odds as indicated for the horsepower circuits. FIGS. 7A, 7B
show four ganged rotary switches 7a, 7b, 7c and 7d for Horse No. 1;
7e, 7f, 7g and 7h for Horse No. 2; and 7i, 7j, 7k and 7l for Horse
No. 6. The switches relating to Horses No. 3, No. 4 and No. 5
having been omitted as in previous circuits.
It will be understood that instead of the separate switches on
Circuit Board R and Circuit Board S being ganged together in groups
of four in the manner shown, they could alternatively be ganged
together as a single eight gang rotary switch, for simplicity of
manipulation.
Passing now to the corresponding tote board back and lamps, which
are indicated in FIG. 10 (Circuit Board K), it will be seen that
the selected odds are indicated on row 10d, indicating from
left-to-right the odds one-to-one to ten-to-one for Horse No. 1;
row 10e, indicating from left-to-right the odds one-to-one to
10-to-one for Horse No. 2; and row 10f, indicating from
left-to-right the odds one-to-one to ten-to-one for Horse No. 6.
(Horses No. 3, No. 4 and No. 5 have been omitted.) It will be noted
that the noncommon terminals of each of the indicating lamps in row
10d are progressively numbered from two through 11; in row 10e,
from 12 through 21; and in row 10f, from 52 through 61. The common
number one terminals to each of these lamps are connected together
to the energizing source terminal Z2 of the 6.3 volt, 3 ampere
rectifier 9q of Circuit Board Z (FIGS. 9A, 9B).
Contacts to the lamps in the Odds section of the tote board
(Circuit Board K, FIG. 10) are lighted up at the appropriate
indications in accordance with the odds settings of the dials on
Circuit Board S (FIGS. 7A, 7B), which in the present illustration
are five-to-one for Horse No. 1, three-to-one for Horse No. 2 and
six-to-one for Horse No. 6. The contacts on the bottom dials 7d, 7h
and 7l (Horses No. 1, No. 2 and No. 6) are connected in succession
to the appropriate connections in the Odds section of Circuit Board
K, rows 10d, 10e and 10f, as shown in the following Table IV:

On Circuit Board S, the other end of the circuit for the Odds lamps
passes through contacts 100 on the rotor arms of dials 7d, 7h and
7l, respectively, which contacts are connected together to contact
Z1 of the rectifier 9q on Circuit Board Z (FIGS. 9A, 9B). The
latter is normally connected to each of the common contacts 10 of
the Win, Place and Show tote board relays 9a, 9b, 9c, 9d, 9e, 9f,
9g, 9h and 9i on Circuit Board Z. Thus, current is directed through
the selector arms 100 (Circuit Board S, FIGS. 7A, 7B) to light up
the selected Odds lights on Circuit Board K (FIG. 10). This also
sets up a power contact which will be actuated on operation of the
Win, Place and Show relays on Circuit Board Z, in a manner to be
explained hereinafter.
Let us refer, now, to the corresponding Prices schedules on Circuit
Board K, comprising columns 10g, 10h and 10i. It will be seen that
in the Win column 10g, winning amounts for odds one-to-one through
10-to-one are successively indicated by small lamps, each having
one terminal represented by contacts 62 through 71; in the Place
column 10h, winnings for odds one-to-one through ten-to-one are
indicated by small lamps whose terminals have contacts 72 through
81; and in the Show column 10i, winnings for odds one-to-one
through 10-to-one are indicated by lamps having contacts 82-91.
It will be noted that on the upper three of the four ganged columns
of dials for each horse, as shown on Circuit Board S, the
corresponding dials have similarly numbered contacts; and each of
the similarly numbered contacts is connected together to a common
circuit.
The interconnections between the contacts on the upper three dials
of Circuit Board S, representing each of the horses, and the
corresponding contacts on the Prices columns 10g, 10h and 10i of
Circuit Board K (FIG. 10) are shown in the following Table V.

The common contacts 1 of each of the indicating lights in columns
10g, 10h and 10i are connected together to terminal Z2 of the 6.3
volt, 3 ampere rectifier 9q on Circuit Board Z (FIGS. 9A, 9B).
Completing these circuits, it will be noted on Circuit Board S
(FIGS. 7A, 7B) that in the ganged rotary switches relating to the
tote board indications for Horse No. 1, the rotary arm 103 of
rotary switch 7a, rotary arm 102 of rotary switch 7b, and rotary
arm 101 of rotary switch 7c, are respectively connected to Z
contacts Z147, Z148 and Z149 of the terminal strip 9n on the
Circuit Board Z, which is shown as FIGS. 9A, 9B. Similarly, of the
ganged rotary switches on Circuit Board S relating to Horse No. 2,
rotary arm 106 of rotary switch 7e, rotary arm 105 of rotary switch
7f and rotary arm 104 of rotary switch 7g are respectively
connected to contacts Z150, Z151 and Z152 on the terminal strip 9n
(Circuit Board Z). Likewise, of the ganged rotary switches on
Circuit Board S relating to Horse No. 6, rotary arm 118 of rotary
switch 7i, rotary arm 117 of rotary switch 7j and rotary arm 116 of
rotary switch 7k are respectively connected to contacts Z162, Z163
and Z164 on terminal strip 9n (Circuit Board Z).
Let us refer to the Finish schedule, indicated in columns 10j, 10k
and 10l of Circuit Board K (FIG. 10).
In column 10j, contacts 92, 93 and 94 (for Horse No. 1) are
respectively connected to contacts Z147, Z148 and Z149 of the
terminal strip 9n of Circuit Board Z (FIGS. 9A, 9B).
In column 10k (Circuit Board K), contacts 95, 96 and 97 (for Horse
No. 2) are respectively connected to contacts Z150, Z151 and Z152
on terminal strip 9n of Circuit Board Z.
In column 10l (Circuit Board K), contacts 107, 108 and 109 (for
Horse No. 6) are respectively connected to contacts Z162, Z163 and
Z164 on terminal strip 9n of Circuit Board Z.
As with the other tote board lights on Circuit Board K, the common
contacts 1 of each of the indicating lights in columns 10j, 10k and
10l are connected together to terminal Z2 of rectifier 9q on
Circuit Board Z, which furnishes the power for the tote board
lights.
Contacts Z147, Z148 and Z149 (for Horse No. 1) on terminal strip 9n
of Circuit Board Z are respectively connected to normally open
contact 16 for Win relay 9g, to normally open contact 22 for Show
relay 9d, and to normally open contact 27 for Place relay 9a.
Contacts Z150, Z151 and Z152 (for Horse No. 2) are respectively
connected to normally open contact 33 for Win relay 9h, to normally
open contact 39 for Place relay 9e and to normally open contact 44
for Show relay 9b.
Contacts Z162, Z163 and Z164 (for Horse No. 6) are respectively
connected to normally open contact 101 for Win relay 9i, to
normally open contact 107 for Place relay 9f and to normally open
contact 112 for Show relay 9c.
When any of the aforesaid relays is energized, the respective
contacts mentioned above are closed to make connection with common
contacts 10, which are all connected together to contact 1 of the
rectifier 9q, to establish an energizing circuit through the
appropriate lights in the Finish and Prices columns on the tote
board, Circuit Board K (FIG. 10).
LAP COUNTER SWITCHES
In addition to the Win, Place and Show rotary switches on Circuit
Board S (FIGS. 7A, 7B) are a series of additional rotary switches,
one corresponding to each horse, which are designated the Lap
Counter Switches.
Each of these ganged, double-poled switches has a pair of rotor
arms, each of which is simultaneously set at one of two positions,
Sprint or Distance, depending on whether one or two laps is desired
for the race. Table VI, which follows, shows the corresponding
connections between dials 7m, 7n and 7p of Circuit Board S and
terminal strip 9p of Circuit Board Z (FIGS. 9A, 9B).

TOTE BOARD RELAYS
Referring in detail to Circuit Board Z (FIGS. 9A, 9B), power for
the Tote Board Relays is furnished from the 6.3 volt, 1.2 ampere
rectifier 9aa, having terminal contacts 3 and 4.
Circuit Board Z shows an array of Win, Place and Show relays for
each of the horse circuits, and in addition, three common relays
for Win, Place and Show and a cut-off relay.
The connections to the energizing circuits for each of the
four-pole double-throw Win, Place and Show relays, for each of the
Horses No. 1, No. 2 and No. 6 are indicated in tabular form on
Table VII, together with the connections to the six-pole
double-throw common Win, Place and Show relays, which have one set
of contacts for each horse in the race. In the present
illustration, three sets of contacts are omitted from each of the
common relays 9j, 9k and 9l as Horse circuits No. 3, No. 4 and No.
5 are not shown. ##SPC3##
In addition, the cut-off relay 9m is shown on Circuit Board Z
(FIGS. 9A, 9B). The energizing circuit of the latter passes from
contacts 132 to 138. Contact 132 is connected through the normally
open contacts Z8 for each of the Show relays 9a, 9b and 9c. When
one of the latter is operated, energizing connection is made
through contacts W181 and W182 of master switch 4h of Circuit Board
W (FIGS. 4A, 4B) to terminal Z3 of rectifier 9aa (Circuit Board Z).
Contact 138 on relay 9m is connected through normally open contact
Z136, Z126 and Z119 of the common Show, Place and Win relays 9l, 9k
and 9j, in series, ultimately to contact Z4 of rectifier 9aa.
When cut-off relay 9m of Circuit Board Z is energized, it opens the
normally closed contacts 145 and 146 to contact W189 in the on-off
power switch 4q of Circuit Board W. This shuts off power to the
relays 4i, 4j, 4k and 4l of the First and Second Timer Circuits
thereby cutting off their operation.
At the completion of a race, the first motor driven horse to cross
the finish line (Horse No. 6 in the present example) encounters the
insulated section of the track, section 3c of Circuit Board Y (FIG.
3). The No. 6 Horse is then disposed between contacts Y11 and Y12
of section 3c, which are respectively across contacts Z176 and Z194
(terminal strip 9p), which are across contacts S153 and S154 to the
rotors of the lap counter switch 7p on Circuit Board S (FIGS. 7A,
7B). For present purposes, the ganged rotor switch on Circuit Board
S is set in Sprint position for all of the horses, with rotor S153
connected to peripheral contact S139, and rotor 154 connected to
peripheral contact S141. Contact S139 is connected to contact Z170,
and contact S141 to contact Z188, both of the latter, on terminal
strip 9p of Circuit Board Z (FIGS. 9A, 9B).
Current then flows from contact Z4 of the 6.3 volt, 1.2 ampere
rectifier 9aa, through contact Z188 of terminal strip 9p, contact
S141 and rotor arm S154 of lap counter switch 7p (Circuit Board S,
FIGS. 7A, 7B), to contact Z194 on terminal strip 9p (Circuit Board
Z) and contact Y12 on one rail of track section 3c (Circuit Board
Y, FIG. 3). Current passes through the motor-shunting diode 2b of
the horse circuit (FIG. 2) to contact Y11 on the other rail of
track section 3c (FIG. 3) which leads to contact Z176, on terminal
strip 9p of Circuit Board Z. Current then passes through the other
rotor arm 153 on lap counter dial 7p on Circuit Board S and to
peripheral contact 139, from which it passes to contact Z170 on
terminal strip 9p of Circuit Board Z. From this point the current
passes to Z96, which is one terminal of the energizing circuit of
relay 9i, which is the Win relay for Horse No. 6.
To complete the energizing circuit, the other terminal 97 of the
Horse No. 6 Win relay 9i is connected through the normally closed
contacts 115 and 9 of the common Win relay 9j to the other terminal
Z4 of the rectifier 9aa.
When Win relay 9i is operated, it performs the following
functions.
First, it locks up by closing its normally open contacts 100 and 9,
making connection to terminal Z4 of the rectifier 9aa; and closing
its normally open contacts 98 and 5, making contact to W181 of
Circuit Board W (FIGS. 4A, 4B), which ultimately leads through the
closed master switch 4h to contact Z3 of rectifier 9aa on Circuit
Board Z (FIGS. 9A, 9B).
Secondly, it closes its normally open contacts 10 and 101, thereby
connecting terminal 1 of rectifier 9q through Z contact 162 on
terminal strip 9n, to contact K107 in the Win column 9l on Circuit
Board K (FIG. 10); and contact S118 on dial 7i of Circuit Board S
(FIGS. 7A, 7B). This supplies energy to light up a lamp behind a
tile indicating Horse No. 6 in the winning position on the tote
board.
It will be recalled that the Win, Place and Show switches on
Circuit Board S have been positioned prior to the race, in
accordance with the selected odds of six-to-one for Horse No. 6,
five-to-one for Horse No. 1 and three-to-one for Horse No. 2.
Current is caused to pass through the rotor arm 118 of dial 7i on
Circuit Board S to K67 in column 10g (Circuit Board K) of the
Prices column on the tote board, lighting up the winning price of
$14.00. In order to obtain the Place and Show prices on the tote
board for the winning horse, one reads horizontally across the row
showing the winning price, which in the present case would give
$5.80 for Place and $4.20 for Show.
The third function performed by the Win relay 9i (Circuit Board Z)
is to break the energizing circuits to the Place and Show relays so
that they cannot operate. The circuit to the Place relay 9f is
broken by breaking the normally closed contacts 98 and 99, the
latter being connected to the terminal of contact 102 of relay 9f
and to the terminal of contact 108 (through contacts 104 and 105)
of relay 9c. This prevents relays 9f and 9c from energizing.
The fourth and final function performed by operation of Win relay
9i is to close its contacts 5 and 6. The former contact leads
through contact W181 on the master switch 4h of Circuit Board W
(FIGS. 4A, 4B), ultimately to contact Z4 of rectifier 9aa, to
supply power through contact 6 to terminal 125 of relay 9j, causing
it to energize.
Again referring to Circuit Board Z (FIGS. 9A, 9B), when the common
Win relay 9j operates, it transfers the rectifier current from one
side of the coils of the Win bank of relays 9g, 9h and 9i, for each
of the horses, to one side of the coils of the corresponding Place
bank of relays 9d, 9e and 9f. This is accomplished by breaking
contact between its common contacts 9, which lead to terminal Z4 of
rectifier 9aa, and contact 116 to the energizing circuit of relay
9g, contact 117 to the energizing circuit of relay 9h, and contact
115 to the energizing circuit of relay 9i. Contact is then made
between each of the contacts 9 of relay 9j and its normally open
contacts 119, which are respectively connected through each of the
normally closed contacts 121 of common Place relay 9k. The normally
closed contacts 121 of the latter respectively lead to: contact Z18
(energizing circuit of Place relay 9d); contact Z37 (energizing
circuit of Place relay 9e); and contact Z103 (energizing circuit of
Place relay 9f). All of these steps are carried out in
milliseconds, conditioning the tote board relays to respond to the
second horse crossing the finish line.
In the present illustrative embodiment, the second horse crossing
the finish line is Horse No. 1. Upon making contact with the
insulated section of track 3a at the finish line section for Horse
No. 1 (Circuit Board Y, FIG. 3), the horse completes the circuit
between contacts 1 and 2 connecting contacts Z171 and Z189 on
terminal strip 9p of Circuit Board Z (FIGS. 9A, 9B), which are
respectively connected to rotor arms 143 and 144 on lap counter
dial 7m (Circuit Board S, FIGS. 7A, 7B). The latter, being set in
Sprint position, contact is respectively made with peripheral S
contacts 119 and 121, which are respectively connected to Z165 and
Z183 on terminal strip 9p of Circuit Board Z. Contact 165 leads to
contact Z11 and through the normally closed contacts 13 and 14 of
Win relay 9g for Horse No. 1 to contact 17 in the energizing
circuit of Place relay 9d. It will be recalled that Win relay 9g
cannot operate because common relay 9j transferred power from the
Win bank of relays to the Place bank of relays. Thus, an energizing
circuit is set up through contact Z183, terminal strip 9p, to
contact Z4 of rectifier 9aa, providing power for operation of the
Place relay 9d for Horse No. 1.
Operation of the latter causes the following functions to be
performed:
First, it breaks contact between normally closed contacts 19 and 20
leading to contact Z23 in the energizing circuit of Show relay 9a
for Horse No. 1, so that the latter cannot function.
Secondly, it lock-operates through its own contacts by closing
normally open contacts 21 and 9, thereby applying power from
terminal Z4 of rectifier 9aa to terminal Z18 of the 9d relay
windings.
Third, it lights the finish lamp in the Place row 10b for Horse No.
1 by closing its normally open contacts 10 and 22. This applies
power from contact Z1 of rectifier 9q through contact Z148 on
terminal strip 9n of Circuit Board Z (FIGS. 9A, 9B), which leads to
contact K93 on Circuit Board K (FIG. 10).
Contact Z148 also leads to S102 on dial 7b of Circuit Board S
(FIGS. 7A, 7B). The preset odds for Horse No. 1 having been
five-to-one, armature S102 is connected to peripheral contact 83,
which leads to K76 in Prices column 10h (Circuit Board K),
illuminating the light behind a tile reading $5.20 for Place.
Reading to the right in column 10i, the player can also collect
$3.80 for Show.
Fourthly, Place relay 9d (Circuit Board Z) closes its normally open
contacts 5 and 7, energizing common Show relay 9k. To do this,
power is applied from contact Z3 of rectifier 9aa through the
master switch 4h on Circuit Board W (FIGS. 4A, 4B) to terminal Z128
of the energizing circuit of common Show relay 9k (Circuit Board
Z).
When operated, this latter relay functions to transfer current from
one side of the coils of Place relays 9d, 9e and 9f (Circuit Board
Z) to one side of the coils of the Show relays 9a, 9b and 9c. This
is carried out by breaking connection between each of its contacts
120, 122 and 131 and common contacts 121, which leads through
contact 9 of relay 9j to the source of power at terminal Z4 of
rectifier 9aa. Contact 121 is then closed to each of its normally
open contacts 126, which lead through the normally closed contacts
of common Show relay 9l to the energizing circuit of each of Show
relays 9a, 9b and 9c, conditioning each of these for the third
horse to cross the finish line.
In the present illustration, the third horse to cross the finish
line is Horse No. 2, for which three-to-one odds were selected
prior to the beginning of the race. At this point in the race Horse
No. 2 enters the insulated section 3b of track as shown in FIG. 3,
his circuit disposed across contacts 3 and 4 which are respectively
connected between contacts Z172 and Z190 on terminal strip 9p of
Circuit Board Z (FIGS. 9A, 9B) and corresponding contacts S145 and
S146 to the rotors of dial 7n of the Lap Counter Switch of Circuit
Board S (FIGS. 7A, 7B) which, as in the previous switches, is set
at Sprint. The two rotors 145 and 146 are respectively connected to
peripheral contacts S123 and S125, which are respectively connected
between contacts Z166 and Z184 on Circuit Board Z. Contact 184 of
terminal strip 9p is connected to contact Z4 of rectifier 9aa, and
serves to supply power to terminal Z28 of the coil of Win relay 9a
for Horse No. 2. But the energizing circuit of Win relay 9h is
broken by the operation of common Win relay 9j; and the energizing
circuit of Place relay 9e is broken by the operation of common
Place relay 9k. Therefore, power from rectifier 9aa is ultimately
transferred through the normally closed contacts of relays 9h and
9e through the energizing circuit from contacts 40 to 41 of Show
relay 9b. Operation of relay 9b causes the following functions to
be performed:
First, it closes its normally open contacts 10 and 44, connecting
power from contact Z1 of rectifier 9q through contact Z152 on
terminal strip 9n of Circuit Board Z (FIGS. 9A, 9B). This
illuminates lamp K97 of Circuit Board K (FIG. 10), indicating that
Horse No. 3 is in Show position. Simultaneously, since odds of
three-to-one have been preset, energizing current passes through
contact Z152 on terminal strip 9n of Circuit Board Z to armature
S104 of dial 7g of Circuit Board S (FIGS. 7A, 7B), and to
peripheral contact S70. The latter is connected to contact K84,
lighting the lamp under $3.00 in the Show column 10i of the Prices
schedule on the tote board of Circuit Board K.
Second, Show relay 9b lock-operates by closing its normally open
contacts 9 and 43, to connect contact Z4 of rectifier 9aa to
terminal 41 of its energizing circuit.
Third, it operates its normally open contacts 5 and 8 to energize
common relay 9l by completing the power circuit from contact Z3 of
rectifier 9aa through master switch 4h on Circuit Board W (FIGS.
4A, 4B) to terminal Z130 of the relay energizing circuit.
When relay 9l operates, it removes power from the energizing
circuits of each of the Show relays 9a, 9b and 9c by opening
connection between its contacts 134 and each of contacts 133, 135
and 143, so that a fourth horse crossing the finish line in close
proximity to the third horse would not register on the tote board.
It completes connection of each of its contacts 134 with its
respective contacts 136 to the energizing circuit of cut-off relay
9m. The latter opens its normally closed contacts 145 and 146,
cutting off power from master switch 4q on Circuit Board W (FIGS.
4A, 4B) to the timing circuits, and thereby turning off the driving
mechanism until the following game begins. The numbers and prices
of the horses remain illuminated on the tote board (Circuit Board
K, FIG. 10) through the lock-up of relays 9i, 9d and 9b on Circuit
Board Z (FIGS. 9A, 9B).
The two start-stop switches 4p and 4q of Circuit Board W should
then be turned to "off" position. The tote board reset switch 4h is
then turned off, deenergizing the locked up relays 9i, 9d and 9b by
breaking the circuit from their respective contacts 98, 19 and 42
to their common contact 5, which leads through switch 4h. This
causes each of the aforesaid relays to drop its contacts,
extinguishing the corresponding tote board lights, and restoring
the tote board to normal condition for the next race.
The horses can then be lined up in the start position as indicated
on Circuit Board Y (FIG. 3). Operation of tote board reset switch
4h and the two startstop switches 4p and 4q of Circuit Board W then
starts a new race.
Although the indicating means shown on Circuit Board K in the
embodiment under description take the form of conventional lamps,
it will be apparent to those skilled in the art that other types of
indicating means can be substituted for the lamps, such as, for
example, digital indicators.
FUNCTION OF LAP COUNTER CIRCUITS AND OPERATION OF TWO LAP RACE
The foregoing description covered a single lap race from start to
finish, the ganged lap counter relays 7m (for Horse No. 1), 7n (for
Horse No. 2) and 7p (for Horse No. 6) having each been set with
their two rotor arms respectively in Sprint position on each of the
dials.
If it is desired to have a two lap race, the six ganged rotors on
dials 7m, 7n and 7p (together with the dials of Horses No. 3, No. 4
and No. 5, not shown) are moved to the Distance position, as
indicated on the respective dials. These connections are indicated
in Table VI hereinbefore.
This serves to transfer the rails of the finish line sections 3a,
3b and 3c of Circuit Board Y (FIG. 3) from their connections with
terminal Z4 of rectifier 9aa and the tote board relays of Circuit
Board Z (FIGS. 9A, 9B), across contacts V78 and V79 of the common
rheostat 6bb of Circuit Board V (FIG. 6), through the common
normally open contacts T6 and T7 of each of the lap counter relays
8b, 8c and 8d of Circuit Board T (FIG. 8).
The energizing connections and the contact connections of lap
counter relays 8b, 8c, 8d, 8e, 8f and 8g are shown in tabular form
in Table VIII. ##SPC4##
Rheostat 6bb of Circuit Board V (FIG. 6) is connected across
contacts V7 and V8 of the common power rectifier 6q, which
functions to furnish common power to the finish line sections 3a,
3b and 3c of Circuit Board Y (FIG. 3) corresponding to each of the
horse circuits No. 1, No. 2 and No. 6, under description. Thus,
constant power appears in all sections of track at the finish line.
Consequently, when horses reach the finish line on the first lap of
the race, they do not register on the tote board; but their motors
receive current which carries them over these sections of track
(3a, 3b and 3c) of Circuit Board Y to the next sections of track
(3d, 3e and 3f) which are also insulated from the other sections of
track, and are not connected to any sources of power.
In the example under description, when Horse No. 6 reaches the
finish line section 3c on the first lap, it proceeds to the next
succeeding lap counter section 3f, as previously described. Upon
making contact with track section 3f, Horse No. 6 completes a
circuit from terminal 1 of rectifier 8a of Circuit Board T (FIG.
8), through the contacts of master switch 4n of Circuit Board W
(FIGS. 4A, 4B), the normally closed contacts 5 and 8 of lap counter
relay 8d on Circuit Board T, contact T111 on terminal strip 8h of
Circuit Board T to contact Y23 on one side of track section 3f
(Circuit Board Y). Current passes through the diode across the
horse motor to contact Y24, which is connected through the normally
closed contacts T79 and T78, relay 8d of Circuit Board T, to
contact T77 through the energizing circuit of the corresponding
lock-up relay 8g, completing the circuit to the terminal 2 of
rectifier 8a of Circuit Board T (FIG. 8).
Lock-up relay 8g operates and performs a single function. It
supplies a constant source of power for its own energizing circuit
and for the energizing circuit of lap counter relay 8d, by closing
its normally open contacts 96 and 4, which connect both of these
circuits through the contacts of master switch 4n on Circuit Board
W (FIGS. 4A, 4B) to terminal 1 of rectifier 8a of Circuit Board T,
causing both relays 8g and 8d to lock up.
Operation of lap counter relay 8d performs two functions.
First, it transfers contacts Y23 and Y24 on the lap counter rail
section 3f of Circuit Board Y (FIG. 3) from their connection with
rectifier 8a and lock-up relay coil 8g of Circuit Board T to the
terminals V78, V79 of rheostat 6bb of Circuit Board V (FIG. 6).
This is done by relay 8d closing its normally open contacts 6 and 7
to its contacts 79 and 81, respectively. On Circuit Board V the
opposite terminals V80 and V81 of rheostat 6bb are connected across
terminals V7 and V8 of the common power rectifier 6q which supplies
power for the finish line section on the second lap.
Thus, constant power is now applied to the rails of lap counter
section 3f on the track of Horse No. 6 (Circuit Board Y), enabling
the horse to move over this section to section 3i, where the
electricity is distributed in the form of random pulses by the
sequential selector of Circuit Board W, in the manner previously
described.
The second function performed by operation of relay 8d on Circuit
Board T (FIG. 8) is to transfer contacts Y11 and Y12 in the finish
line section 3c (Circuit Board Y, FIG. 3) from their connection
with rheostat 6bb and rectifier 6q on Circuit Board V (FIG. 6) to
rectifier 9aa and the tote board relays of Circuit Board Z (FIGS.
9A, 9B), so that the next time the Horse No. 6 encounters the
finish line section 3c, the normal sequence of events will occur as
described hereinbefore with reference to the one lap race. This
function is carried out as follows. Operation of lap counter relay
8d (Circuit Board T) breaks its normally closed contacts 7 and 84,
and 6 and 87, and closes its normally open contacts 84 and 85, and
87 and 88.
Contacts 84 and 87 of relay 8d are respectively connected between
contacts Z182 and Z200 on terminal strip 9p of Circuit Board Z,
which are connected between peripheral contacts S140 and S142 on
lap counter switch 7p on Circuit Board S (FIGS. 7A, 7B). Switch 7p
and the corresponding switches for the other horses, now have their
rotors placed in the Distance position as indicated on the dials.
Thus, contacts S140 and S142 are respectively connected between
rotors 153 and 154, which are, in turn, connected between contacts
Z176 and Z194 on terminal strip 9p of Circuit Board Z which are
across horse circuit terminals Y11 and Y12 on finish line section
3c of Circuit Board Y.
On Circuit Board T, contacts 85 and 88 of relay 8d, which in the
present condition are connected to the horse terminals, are
respectively connected between contacts Z170 and Z188 on terminal
strip 9p of Circuit Board Z (FIGS. 9A, 9B). Contact 170 leads to
terminal Z96 of the Win relay 9i for Horse No. 6; and contact 188
leads to terminal Z4 of rectifier 9aa for energizing circuit
including the Win relay when Horse No. 6 reaches the finish line
section 3c (Circuit Board Y, FIG. 3), the second trip around.
It will be appreciated that the sequence of events is similar for
each of the horses encountering the finish line on the first and
second laps. The third horse to complete two laps actuates its Show
relay, which, in turn, actuates cut-off relay 9m on Circuit Board
Z, cutting off the game in the manner previously described with
reference to a single lap race.
MISCELLANEOUS FUNCTIONS
The make-when-depressed buttons 6j, 6k and 6l individual to each
horse, which are found on Circuit Board V (FIG. 6), when depressed
complete a circuit from the corresponding one of rheostats 6m, 6n
and 6p (also Circuit Board V) to the power connection (bypassing
the contacts of horsepower relays 6d, 6e and 6f, Circuit Board V)
to the track (Circuit Board Y). This supplies constant power to the
track causing the corresponding numbered horse to move. In this
manner, horses that were stranded in the backstretch, when the game
turned off at the end of the race, can be brought back to the start
position.
Adjusting the rheostats 6m, 6n and 6p (one for each horse) on
Circuit Board V to control the speed of the horses should be
performed as follows at the beginning of each game. All of the
horses are placed in a straight line on the straight section of
track preceding a curve and the individual rheostats 6m, 6n and 6p
adjusted so that one pulse of current when the game is turned on,
carries all of the horses to a position on the curve so that a
straight line can be drawn across their front ends, as illustrated
in FIG. 11 of the drawing.
In order to accomplish this, the horse on the outside oval must be
travelling faster than the horse on the next inner oval, etc., the
horse on the innermost oval travelling at the slowest rate. This is
necessary because the innermost horse has less distance to travel
than any other horse; and the further the outpost, the further the
horse has to travel. This is compensated for by increasing the
speed of the horses as you move outward from number one.
At the very beginning of each game, after switches 4p and 4q of
Circuit Board W (FIGS. 4A, 4B) are turned to their "on" positions,
in order to increase the randomness of the system, the contact 159
of relay 4i, First Timer, is manually depressed to contact 160,
closing the circuit to stepping switches 4a and 4b, and causing the
system to move through a single step. This prevents any possibility
of any repetitive pattern being set up, based on that of the last
game played.
A particular feature of the present embodiment is that all of the
relays are designed for fast operation, after not longer than about
one seventy-fifth of a second, and preferably, as fast as one one
hundred twenty-eighth of a second. This serves to prevent dead
heats from occurring between two or more horses. In the embodiment
under description, the relays are preferably designed to operate at
12 volts, although this may be varied, as convenient. In any case,
it is undesirable to use high voltages because of the safety
factor. In the present embodiment, the following illustrative types
of relays were used, as disclosed in the Distributor Stock
Catalogue, issued May 1, 1969, by Sigma Instruments, Inc., 299
Forest Avenue, Paramus, N.J. 07625.

in the present illustrative embodiment, each of the stepping
selector relays 4a through 4f, as shown on Circuit Board W (FIGS.
4A, 4B) is a continuous operation rotor-relay of the type
manufactured by Guardian Electric Co., Chicago, Ill., under the
trade name "Rotomite" stepping switch, as item number
1R-705-12P-24D in their catalogue published in 1969. An important
feature of this type of selector is that when it reaches the last
step in the series, it automatically returns to the first step for
recycle, without the actuation of a specific release mechanism.
It will be understood that the present invention is not limited to
any of the specific forms or mechanisms shown by way of
illustration. For example, although the particular model described
is a six horse race, it will be appreciated that any number of
horse units can be employed, and furthermore, that the race can be
designed to have as many laps as desire. Moreover, although the
model described is a horse race, it will be appreciated that the
concept of the present invention can be adapted to many different
types of racing units, such as, for example, racing cars, boats,
men, etc.
As one alternative to the mechanism indicated on Circuit Board W
(FIGS. 4A, 4B) in the present illustrative embodiment, a single
selector mechanism having 48 contacts (or other convenient number),
which is directly driven by the First Timer pulse circuit, could be
substituted for the system including primary selectors 4a, 4b and
auxiliary selectors 4c, 4d, 4e and 4f. Moreover, it is within the
contemplation of the invention that a variable speed motor driven
commutator which continuously moves through 48 contacts (or
whatever number of contacts is arbitrarily selected) could be
substituted for the latter combination. The commutator would have
its speed geared down to correspond to the pulsing speed of the
Second Timer, acting independently. A further alternative would be
to provide a separate motor driven commutator for each horse.
Moreover, as a further alternative, instead of each of the horses,
or other racing units, having individual driving motors, a single
motor can be connected to energize individual units at different
steps of the commutator, whenever there is a coincidence with an
independently driven pulsing unit.
More broadly, the concept of the present invention is applicable to
other types of systems, such as, for selecting random numbers, and
for many and varied purposes.
