SWEEPSTAKE PROGRAMMER
Abstract
A game in which a player attempts to match a number or design
selected by a chance mechanism. The player sets the game into
operation by inserting a first token to operate the chance
mechanism for selecting a number or design by the machine, which is
to be matched by the player. The token also releases the selecting
mechanism by which the player makes his selection. The insertion of
a security key releases the trip mechanism for operation by the
player. By operating the trip mechanism after the insertion of the
security key the player attempts to match the first two numbers (or
designs) selected by the machine. The insertion of a second token
or other triggering means allows the player a choice of selecting a
third number and a third token allows the player to select a fourth
number. In the event the player matches the selected numbers the
machine prints a tab indicating the correct selection.

Description
This invention relates to a coin operated game apparatus and more
specifically to an apparatus in which the player attempts to match
a combination of numerals or other designs selected by the
apparatus.
There are a number of coin operated game devices in which the
player has no choice of selection and his chance of winning or
losing is preselected by the machine. There are also games of
chance in which the player has only a limited selection.
It is an object of this invention to provide a game of chance in
which the player can make a selection of one or more combinations
of numerals and or designs to match a selection made by the
machine.
It is a further object of this invention to produce an apparatus as
aforesaid in which the winning selection is printed on a voucher
which is supplied to the player.
It is a further object of this invention to produce an apparatus as
aforesaid which can provide for the selection of large numbers of
combinations using only simple electrical components.
These and other objects of the invention will become manifest upon
reading the following description in conjunction with the
accompanying drawing wherein:
FIG. 1 is a perspective view of the apparatus;
FIG. 2 is a side view thereof;
FIG. 3 is a phantom view showing in diagrammatic form the
arrangement of the major parts of the apparatus;
FIG. 4 is a circuit diagram showing some of the operating
circuits;
FIG. 5 shows the selector and selecting circuits associated with
the second column of switches;
FIG. 6 shows the selector and selecting circuits associated with
the third column of switches;
FIG. 7 shows the selector and selecting circuits associated with
the fourth column of switches;
FIG. 8 shows a detail of the selector switch for use with the first
column of switches;
FIG. 9 is a view along the line 9-9 of FIG. 8;
FIG. 10 is a view along the line 10-10 of FIG. 8;
FIG. 11 is a view similar to FIG. 10 and showing the selector
switch for use with the second column of switches;
FIG. 12 is a detail view of the switch-operating mechanism
associated with the first column of switches;
FIG. 13 is a detail taken along the line 13-13 of FIG. 12;
FIG. 14 is a view taken along the line 14-14 of FIG. 12; and
FIG. 15 is a diagrammatic view of the blind and its operator.
With reference to FIG. 1 of the drawing there is illustrated a case
C for housing the main operating parts of the apparatus. A
plurality of token receiving openings A2, C2, D2 and a security
opening B2 are located at the top of the case for receiving tokens
during the course of the play. A plurality of selecting knobs A4,
B4, C4, D4 are connected to switch operators in the case and are
slidably mounted along slots A6, B6, C6, D6 for selecting a number
or design. The selection is shown in windows A8, B8, C8, D8
associated with each knob and slot. The master combination which is
selected by the apparatus is displayed in window W but is withheld
from view by a blind till the player has made his selection and has
finalized it by operating the handle H in the direction of the
arrow 2.
The game is played by depositing a token in slot A2. This operates
a chance device whereby the apparatus is operated to produce a
master number in window W, but the number is unknown to the player.
The token also activates the selecting mechanism to permit the
player to select his matching number by sliding the knobs along the
slots A6, B6, C6, and D6. The number selected by the player is
always visible in windows A8, B8, C8, and D8. His selection can be
changed till he makes it final in the manner noted above. A key
must be deposited in slot B2 in order to allow the player to make
his selection final. If desired the player can limit his selection
to the first two numbers of the master combination by making his
selection final after depositing the second key. The first three
numbers of the master combination can be played by depositing a
token in slot C2 and all four numbers can be played by depositing a
token in slot D2. The selection is made final as noted above and
the presence of a winning number is indicated by the light L which
carries instructions to operate the switch S. Operation of the
switch expels a tab, through the tab slot TS, on which is printed
the winning combination.
CHANCE MECHANISM
The chance mechanism comprises a plurality of selectors indicated
in general by the legends AC, BC, CC, and DC. Each selector
comprises a motor M which remains connected to a voltage source
through a master switch (not shown) and rotates at all times except
for the period during which a selection is retained. Each motor
drives a disc 10 carried on armature shaft 11 and having secured
thereto an operating pin 12. A switch plate 14 is carried by the
armature shaft 16 of a solenoid 18 and is moved toward the disc 10
when the solenoid is energized and is moved away from disc 10 by a
spring mechanism in the solenoid when the solenoid is deenergized,
in the directions indicated by the double-headed arrow 20 in FIG.
8.
The plate 14 of selector AC is formed with a pair of diametrically
opposed elongated openings 22,24, the plate of selector BC is
formed with three openings 26,28,30, the plates of selectors CC and
DC are formed with four openings. The faces of plates 14 facing
discs 10 are formed with a guide track 32 for guiding the head 13
of pin 12. A switch 34 is secured to each plate 14 adjacent each
opening. Each switch comprises a pair of fixed contacts 36 and 38
and a movable contact 40 normally biased into engagement with
contact 36. The movable contact carries an insulating contact shoe
42 extending into the adjacent opening. When the solenoid 18 is
energized the plate 14 is shifted toward rotating pin 12. The head
13 of the pin will engage in the first elongated opening it finds
to press on shoe 42 to separate contacts 36,40, whereby to
deenergize the motor and close contacts 38,40 to form a circuit
therethrough.
SELECTING MECHANISM
The selecting mechanism comprises four columns of selecting
switches. Column A contains two switches 2A and 4A. Column B
contains three switches 2B, 4B, and 6B. Column C contains four
switches 2C, 4C, 6C, and 8C and column D contains four switches 2D,
4D, 6D, and 8D. Each switch comprises a fixed contact 44 and a
movable contact 46 normally biased out of engagement with the fixed
contact. Each column is supplied with an operator 48 which is
provided with a cam 50 for engagement with an insulator 52 of
movable contact 46 to move the contact into engagement with fixed
contact 44. The operators are shifted longitudinally by means of
knobs A4, B4, C4 and D4. The cam 50 is held to keep closed the
selected contacts by means of detents which detain the operators in
the location selected by the player.
ACTIVATING MECHANISM
The chance and selector mechanisms are normally locked in the
inoperative state and are activated by depositing a token in
opening A2 to close contacts 54,56 to complete a circuit from a
voltage source to solenoids 58 and 60 through lines 61,62 and to
solenoids 18 through line 64. The armature shaft 57 of solenoid 58
carries a pin 63 which is slidably entered into a recess 65 of
operator 48 by the bias of spring 64 when the solenoid is
deenergized. The pin is removed from the recess when the solenoid
is energized to allow the shifting of the operator.
A housing 66 is carried by armature shaft 68 of solenoid 60 and
houses a spring 70. The housing is provided with a recess for
retaining a detent ball 72 for engagement with recesses 74 in
operator 48 in column A. When solenoid 60 is energized spring 70 is
sufficiently compressed to urge ball 72 into a recess 74 for
retaining the operator in a selected position.
A spring 76 is secured to a bracket 78 secured in the case C and is
secured to operator 48. The spring is under sufficient tension to
move the operator when solenoid 60 is deenergized.
A security key deposited in opening B2 will close contacts 55,59 to
complete a circuit from line 61 to switch 1A. The movable contact
67 of switch 1A is normally in engagement with fixed contact 69 and
is held out of engagement by cam 50 of operator 48 when the
operator is in its uppermost position. The electromagnet BE will
attract movable contact 55 to maintain contacts 55 and 59 in
engagement. The fixed contact 69 is connected to solenoid 124 by
line 71.
A token deposited in opening C2 will close contacts 162 and 163 and
the contacts will remain closed by the attraction of electromagnet
CE on the moveable contact 162. The movable contact will then be
disengaged from line 164.
A token deposited in opening D2 will separate movable contact 172
from line 174 and will close contacts 172 and 173. The contacts
will remain closed by the attraction of electromagnet DE on the
movable contact 172.
PRINTING MECHANISM
The printing mechanism comprises a plurality of printing mechanisms
80, 82, 84 and 86 having index wheels settable to form a bank of
designs, such as numbers, which are operated by the chance
mechanism to present the master combination elements toward the
paper 88 preparatory for actuation into printing engagement. The
paper is stored in a roll 90 and is led between feeding rollers 92
and 94. The roller 92 is rotated by motor 96 to feed a tab with the
winning combination printed thereon. The printing wheels are
stamped into printing engagement by operation of solenoid 98 which
then withdraws the printing wheels and opens the circuit
therethrough.
A solenoid 100 carries a locking rod 102 for engagement with an
opening 104 in the end of roller 92. The roller is of sufficient
circumference between openings 104 to expel a tab having the
printed number thereon. The armature of the solenoid carries a
plate 106 having a resilient reed 108 connected thereto. The
movable contact 110 is carried by the reed to move into and out of
engagement with the fixed contact 112.
Solenoid 100 is energized when there is a winning selection and
removes the rod 102 from an opening 104 and closes contacts 110 and
112. Closing of contacts 110 and 112 energizes solenoid 98. A time
delay switch 114 prevents operation of the motor 96 till the
printing wheels have been contacted with the paper and withdrawn.
The switch then closes to allow the motor to make a partial
rotation to move 102 and 104 out of engagement to maintain contacts
110 and 112 closed to hold energized the indicating light L.
Operation of switch S will again energize motor 96 to expel the tab
and align 102 and 104 to open contacts 110,112 to extinguish the
light and deenergize the motor. A time delay switch 111 will open
the circuit to solenoid 100 after the motor 96 has made the partial
rotation.
TRIP MECHANISM
The trip mechanism comprises a bellcrank lever pivotally mounted at
115 on the case C and having an arm H which is used as the
operating handle and an arm SW which is used to operate movable
contact 116 through an insulating post 118 and the movable contact
of a time delay switch 120 through an insulating post 122. Solenoid
124 having a reciprocating armature shaft 126 is mounted in the
case. Shaft 126 normally is extended to engage in an opening 128 in
handle H to lock the handle against unauthorized movement. When a
token is deposited in slot B2 the solenoid is energized to withdraw
the shaft 126 from the opening to permit movement of the handle. A
rod 130 is secured to arm SW and is loosely carried in an ear 132
carried by the blind 134. A pair of springs 136 and 138 support the
blind in a position to cover the window W. When the handle is
pivoted the blind is depressed to reveal the master combination
through the window.
ENERGIZING CIRCUITS
The normally closed contacts of the switches 34 carried by plates
14 are arranged in series to connect a source of voltage to the
motors M. In FIG. 4 a line 150 connects a source of voltage to the
first movable contact of the series and a line 152 connects the
last fixed contact 36 of the series to the motor. A line 154 leads
to ground to complete the circuit. In FIG. 5 a line 156 connects a
source of voltage to motor M2 and a line 158 connects the motor to
the first fixed contact 36 of the series and a line 160 connects
the movable contact of the last switch of the series to a movable
contact 162 of a double throw switch in which the movable contact
is normally in contact with a ground lead 164. In FIG. 6 a line 166
connects a source of voltage to the motor M3 and a line 168
connects the motor to the first fixed contact 36 of the series and
a line 170 connects the last movable contact of the series to a
movable contact 172 of a double-throw switch in which 172 is
normally in contact with a ground lead 174. The connection of motor
M4 is similar to that of M3 but the last movable contact of the
series is permanently connected to ground lead 176. With the
foregoing circuits the motors run until one of the series connected
switches is opened.
A line 300 connects fixed contact 44 of switch 2A to fixed contact
38 of the first of the series of two switches 34 carried by plate
14 and a line 302 connects the fixed contact 44 of switch 4A to
fixed contact 38 of the second of the two series of switches 34
carried by plate 14. Line 304 connects fixed contact 44 of switch
2B to fixed contact 38 of the first of the three series connected
switches 34 on plate 14, line 306 connects fixed contact 44 of
switch 4B with the fixed contact of the second of the series
connected switches 34 carried by plate 14 and a line 308 connects
the fixed contacts 44 of the fixed contact of the third series of
switches 34. Similarly lines 310, 312, 314, and 316 connect the
fixed contacts 44 of switches 2C, 4C, 6C, and 8C to the fixed
contacts 38 of switches 34 carried by plate 14 and lines 318, 320,
322, and 324 connect the fixed contacts 44 of switches 2D, 4D, 6D,
and 8D to the fixed contacts 38 of switches 34 carried by plate
14.
The movable contacts 46 of switches 2A and 4A are connected to line
326, the movable contacts 46 of switches 2B, 4B, and 6B are
connected to a common line 328, the movable contacts 46 of switches
2C, 4C, 6C, and 8C are connected to a common line 330, and the
movable contacts 46 of switches 2D, 4D, 6D, and 8D are connected to
a common line 332.
Registers 334, 336, 338, and 340 are mounted behind window W and
register the numbers selected by the chance mechanism. These
registers are well-known devices and will record a preselected
number upon completing the proper circuit. Register 334 has leads
342,344 connected to fixed contacts 44 of switches 2A and 2B and
will register numeral 1 when line 342 completes a circuit and will
register numeral 2 when line 344 completes a circuit. Similarly
registers 336, 338, and 340 are connected to register numerals 1,
2, 3, or 4 dependent on the completion of the proper circuit.
The printing mechanisms 80,82,84,86 are in parallel circuits with
registers 334, 336, 338, and 340 and will thus present the proper
numeral for printing simultaneously with the presentation of the
proper numeral by the register.
OPERATION
For purposes of explanation the description that follows will be
made on the assumption that the player has selected the winning
number 1123. However, it is to be understood that designs other
than numbers can be used, for example, combinations of grapes,
lemons, oranges, or geometrical figures such as combinations of
circles, squares, etc.
A token is deposited in opening A2 to close contacts 54 and 56. The
contacts remain closed by the attraction of movable contact 54 by
electromagnet AE. Current flows from a voltage source to line 61,
through engaged contacts 54,56, line 62 and to solenoids 58 and 60.
Energization of solenoid 58 will operate to withdraw locking pin 63
from recess 65 to allow the player to slide operator 48 downwardly
to close contacts 67,69 of switch 1A and to close contacts 44,46 of
switch 2A. Energization of solenoid 60 will produce sufficient
force on spring 70 to retain detent ball 72 in the selected recess
74 and to thereby detain cam 50 in engagement with contact 46. A
circuit is also completed to solenoid 18A through line 200 and
ground line 202. A circuit is completed to solenoid 18B through
lines 204 and 206. Similarly, circuits are completed to solenoids
18C and 18D through lines 208,210 and 212,214. Energization of
solenoid 18A will move plate 14 toward rotating plate 10 and cause
the pin 12 to move contact 40 away from contact 36 into engagement
with contact 38 to produce a series circuit with contacts 44,46 of
switch 2A and to open the circuit to the motor M1 as illustrated in
FIG. 4. Similarly plate 14 carrying three switches will be moved to
cause pin 12 to move contact 40 away from contact 36 and into
engagement with contact 38 to produce a series circuit with
contacts 44,46 of switch 2B and to open the circuit to motor M2 as
illustrated in FIG. 5. In FIG. 6 contacts 40 and 38 have been
engaged to form a series circuit with contacts 44,46 of switch 4C
and in FIG. 7 contacts 40 and 38 have been engaged to form a series
circuit with contacts 44,46 of switch 6D and to open the circuits
through motors M3, M4.
Completion of the circuit to switch 2A will complete a circuit from
line 150 through contacts 40,38, line 300, and line 342 to register
334 to cause the register to exhibit numeral 1 in the window.
Similarly a circuit is completed to printing mechanism 80 through
line 343 to orient numeral 1 for printing on the tab.
Completion of the circuit to switch 2B will complete a circuit
through the register 336 from a supply line 337, through line 304,
contacts 38,40, line 160, contact 162 to ground line 164. Register
336 will then exhibit numeral 1 in the window W. Similarly a
circuit is completed through printing mechanism 82 from a supply
line 339 through lines 341,304 to ground to orient the second
numeral 1 for printing on the tab.
Completion of the circuit to switch 4C will complete a circuit from
supply line 341 through register 338 lines
311,312,38,40,36,40,170.172, to ground line 174 and the register
will exhibit the numeral 2 in window W. Similarly a circuit is
completed from supply line 343 through the printing mechanism 84,
line 345, line 311 to ground and numeral 2 will be oriented for
printing on the tab.
Completion of the circuit to switch 6D will complete a circuit from
supply line 347 through register 340 lines 349,322 and the series
arranged switches on plate 14 to ground line 176. Similarly a
circuit is completed from a supply line 351 through printing
mechanism 86, line 353 to ground and numeral 3 will be oriented for
printing on the tab.
Completion of the foregoing circuits completes the selection of the
master number by the apparatus and prepares the number for viewing
in the window W and for printing on the tab.
The player can now make his selection by shifting the operators 48
by means of the attached knobs. Movement of operator 48 downwardly
along column A will close switch contacts 67,69 and contacts 44,46
of switch 2A. Movement of the operators in columns B, C, and D will
close contacts 44,46 of switches 2B, 4C, and 6D. The numbers
selected by the movement of each operator can be viewed through
windows A8, B8, C8, and D8. This operation sets the players
selection of four numbers. By depositing a key in opening B2 switch
contacts 55 and 59 are closed to energize solenoid 124 through
lines 61,71 through closed contacts 67,69. The solenoid will
withdraw pin 126 from opening 128 to free the handle for rotation.
The player can now make his selection of two numbers final by
rotating handle H to close contacts 116,117. A circuit is now
completed from line 150 through contacts 38,40 line 300, switch
contacts 44,46 of switch 2A, line 326, contacts 116,117, solenoid
100, line 328, closed contacts 44,46 of switch 2B line 304,
contacts 38,40 line 160, contact 162 to ground line 164. The
completed circuit energizes solenoid 100 for actuation to close
contacts 110,112 and to complete a circuit from a source line 113
to light L, solenoid 98, and through delay line 114 to motor 96.
The operation of solenoid 98 will print numbers 11 on the tab. The
motor will now rotate sufficiently to cause pin 102 to bear on the
end of roller 92 before being deenergized by the cutoff produced by
delay line 114. The player can now act under instructions to close
switch S. This completes a circuit from line 99 to the motor to
again energize the motor to rotate the rollers 92 and 94 to expel
the printed tab. Alignment of opening 104 with pin 102 will shift
the pin into opening 104 and open contacts 108,110. Time delay
mechanism 120 will retain the electromagnets AE, BE, CE, DE
energized for a sufficient period of time to allow the player to
compare his selection with the master number and will then open the
circuit to deenergize the electromagnets. Upon deenergization of
the electromagnets contacts 54,56 are opened and solenoids 58 and
60 are deenergized. Deenergization of solenoid 60 will release the
pressure on spring 70 such that the detent mechanism cannot
restrain movement of operator 48 against the bias of spring 76. The
operator is therefore biased upwardly to open contacts 44,46 of
switch 2A and open contacts 67,69 of switch 1A. The slanted edge 59
of the operator will bias the pin 63 to the edge of the operator
whereby it will enter into opening 65 to lock the operator in
position for the next play. Opening of contacts 67,69 will
deenergize solenoid 124 to allow armature shaft 126 to be released
for entry into opening 128 of the handle to lock the handle from
unauthorized operation.
Openings of contacts 54,56 will also deenergize solenoids 18. The
solenoids will therefore move plates 14 away from plates 10 to form
the circuits for again energizing motors M. The registers and
printing mechanisms are deenergized and return to their zero
position where the characters 0 are exhibited in the window and
oriented for printing by the printing mechanisms. Deenergization of
electromagnet BE will open contacts 55,59; 162,163; and
172,173.
A token deposited in opening C2 will permit the player to play for
three numbers of the combination. The token will close contacts
162,163 to complete a circuit from line 330 through closed contacts
44,46 of switch 4C, through contacts 36,38,40 of the series
arranged switches 34 to line 170, movable contact 172 to ground
line 174. The grounding circuit for solenoid 100 now includes
series connected switches 4D and 34.
A token deposited in opening D2 will close contacts 172,173 and
open contacts 172,174. Closing of contacts 172,173 will complete a
circuit from line 332 through closed contacts 44,46 of switch 6D,
through contacts 36,38,40 of the series arranged switches 34 to
ground line 176. The grounding circuit for solenoid 100 now
includes series connected switches 6D and switches 34. Operation of
handle H will now complete the play for the four number match.
A four column game has been used to describe this invention but it
is obvious that fewer or a greater number can be used. If desired,
the chance mechanism can be replaced by a selection mechanism
similar to the one described herein to allow one player to set the
master combination and the second player to attempt a match with
his opponent. These and other arrangements will now be apparent
from the foregoing description.
