Description
The present invention relates generally to amusement apparatus and
more particularly to an amusement apparatus of the type commonly
known as a slot machine.
Generally, the amusement apparatus of the present invention
comprises symbol display means for presenting a plurality of
changeable symbols within a viewing area with the symbols in
side-by-side relationship to effect forming in a horizontal row or
rows one or more combination of symbols which have a pre-determined
play value. The means for providing the changeable symbols in the
viewing area can comprise a plurality of rotatable drums or
electro-optical reels mounted in side-by-side relationship. The
term "electro-optical reel" is used to designate an electro-optical
assembly which projects in sequence images of symbols on a
self-contained translucent screen surface to simulate spinning reel
action which gives the appearance of the rotation of a mechanical
reel without requiring moving parts of any type. An
"electro-optical reel" can be operated entirely by combinations of
electronic elements as is well known in the electronic art. The
foregoing electro-optical reels or the conventional rotatable drums
having symbols on the periphery thereof are actuated by a player
depressing a starting button or lever and at the end of a normal
play cycle the sequential change of symbols is stopped by
electronic, electrical or mechanical means with each reel or drum
displaying a symbol in a viewing area and which together form one
or more combinations of symbols in one or more horizontal rows with
certain of the combinations being considered winning combinations
entitling the player to a reward. Heretofore, in an amusement
device of the foregoing type the only participation by the player
has been the starting of the means which displays the symbols in
the viewing area. It would substantially increase the amusement
value of the device, if the player could take a more active part in
selecting or determining the combination of symbols which appear in
the viewing area and increase the frequency of winning
combinations.
It is therefore an object of the present invention to provide an
amusement apparatus of the foregoing type having means for
increasing player participation in the selection of winning
combinations.
Another object of the present invention is to provide an amusement
apparatus of the instant type having means enabling a player to
change one or more of the symbols at the end of a play cycle to
form a winning combination or a combination having a higher play
value.
Other objects of the present invention will be apparent to those

One preferred embodiment of an amusement apparatus embodying the
present invention shown in FIGS.1-7 comprises a machine having a
console type cabinet 10 provided with a viewing area 11 on a front
upper panel 12 of the cabinet 10. The viewing area 11 can, if
desired, be subdivided into three elongated rectangular viewing
areas 13, 14, 15. The cabinet section contains three
electro-optical reels 22, 23, 24 mounted in side-by-side
relationship with the display screen or symbol viewing surface of
each reel disposed in the viewing area 11 with each of the
electrooptical reels 22, 23, 24 displaying at least one and
preferably three vertically aligned symbols which are changeable
sequentially. The assembly of electro-optical reels 22, 23, 24 is
adapted to form at least one and preferably three horizontal rows
or combinations of symbols in the viewing area 11.
The electro-optical reels 22, 23, 24 each has associated therewith
electro-mechanical or electronic means which enables each of the
reels to display a sequence of symbols during a portion of the play
cycle and which stops the sequential display of symbols to effect
"indexing" each reel at the end of the play cycle so that each reel
displays a symbol to form a combination in the viewing area. In
addition, at least one of the electrical reels 22, 23, 24 has
operatively associated therewith player activated means for
shifting or changing one or more of the symbols of a combination
appearing in the viewing area at the end of the play cycle.
In the embodiment of the present invention shown in FIGS. 1-7 of
the drawing the symbol changing electro-optical reels 22, 23, 24
are mounted in a frame 20. A drive shaft 30 is mounted in suitable
bearings with an electric motor 32 secured to the base plate 20
operatively connected to drive shaft 30 through suitable gears to
effect rotation of the shaft 30 when the motor 32 is electrically
driven. The drive shaft 30 has operatively associated therewith
symbol selecting and index assemblies 41, 42, 43 which are
electrically connected with the electro-optical reels 22, 23, 24,
respectively. The drive shaft 30 preferably also has mounted
thereon a random selector assembly 44 which is operatively
connected with a locking means associated with the symbol shifting
means provided for shifting the symbols appearing on at least one
of the electro-optical reels at the end of the play cycle, as will
be described in detail hereinafter.
Each of the symbol selecting and indexing assemblies 41, 42 and 43
comprises a contact plate 45, 46, 47, respectively, supported in a
fixed position by the frame 20 with each of the contact plates 45,
46, 47 having a transverse passage 48, 49, 50, respectively,
therein permitting the drive shaft 30 to pass freely therethrough
substantially perpendicularly to the surface thereof. The contact
plates 45, 46, 47 are made of electrical insulating material, such
as Bakelite, and each has a set of spaced electrical conductive
rivets or contact points 51, 51', 51", respectively, affixed to the
front surface thereof at equally spaced points along the
circumference of a circle, the center of which coincides with the
center of the passages 48, 49, 50, respectively. The number of
contact points 51, 51', 51" in each of the sets correspond to the
number of electrical leads extending from the electro-optical reels
22, 23, 24, respectively, and in the embodiment illustrated there
are sixteen contact points mounted on each of the plates 45, 46,
47.
Wiper assemblies 52, 52', 52" are mounted on the drive shaft 30
opposite the set of contact points 51, 51', 51", respectively. The
wiper assembly 52, as best shown in FIG. 3, and which has a
structure identical to assemblies 52' and 52", comprises a collar
55 providing a suitable abutment surface 56 which engages an
indexing ratchet wheel 57. The indexing ratchet wheel 57 comprises
an outer washer shaped section 58 formed of electrical insulating
material, such as Bakelite, having ratchet teeth 59 formed on the
outer peripheral edge thereof and having the inner edge thereof
secured to a hub section 60 which is mounted on the drive shaft 30.
The number of ratchet teeth 59 formed on the ratchet wheel 57
correspond to the number of contact points 51 on the contact plate
45. The outer lateral surface of the hub section 60 is engaged by a
friction washer 61 mounted on a support washer 62 with the friction
washer 61 being urged into driving engagement with the ratchet
wheel 59 by a spring means 63 supported by a set screw collar 64
secured to the drive shaft 30. The rear surface 65 of the washer
shaped section 58 has mounted thereon a slip ring section 66 spaced
electrically from the hub section 60 with an outwardly extending
resilient wiper member or arm 67, the outer end section of which is
adapted to form a sliding contact with the contact points 51 when
the indexing ratchet wheel 57 is rotated by the drive shaft 30. The
slip ring section 66 is continuously contacted by a slip ring wiper
68 mounted on plate 45 adjacent the axial passage therein. The slip
ring wiper is continuously provided with electrical power for
actuating the electro-optical reel 22 and is placed in electrical
contact therewith by the circuitry disclosed in FIG. 4 of the
accompanying drawing.
The wiper arm 67 of the wiper assembly 52 is maintained in a fixed
position relative to the contact points 51 between play cycles by
an index latch means 70 comprised of an indexing pawl 71 which
normally engages one of the ratchet teeth 59 formed on the
periphery of ratchet wheel 57 and an indexing pawl actuating
solenoid 72 which is activated to effect withdrawal of the indexing
pawl 71 out of contact with the ratchet wheel 57 when play of the
apparatus is started, as will be described hereinafter.
The electrical circuits connecting the contact points 51 and 51' of
the selecting and indexing assemblies 41 and 42 with the
electro-optical reels 22 and 23, respectively, are preferably
identical and are illustrated in FIG. 4 of the drawing specifically
showing the circuitry for the assembly 41. It will be evident from
FIG. 4 that wiper arm 67 is connected in series with the electric
reel 22 across lines 73, 74. When the wiper arm 67 is indexed in
the position shown in FIG. 4 in contact with contact point 51a,
electric current is supplied to the lights illuminating the symbols
BAR-ORANGE-CHERRY of the electric reel 22. If the wiper arm 67 is
advanced to contact point 51b, the symbols which will be
illuminated on electric reel 22 will be PLUM-BAR-ORANGE. And, when
the wiper arm 67 is advanced to contact point 51c, the illuminated
symbols will be BELL-PLUM-BAR. Thus, when the wiper arm 67 is moved
in a counterclockwise direction, the reel 22 is simulating the
downwardly movement of a mechanical reel, as evident from the
sequential movement of the "BAR" symbol from the top, to the middle
and finally to the bottom row of horizontal symbols in FIG. 1.
Reel 24 which has assembly 43 associated therewith also includes
means actuated by the player for changing the symbol displayed
thereby at the end of the play cycle, and the circuitry therefor is
shown in FIG. 5 of the drawing. Thus, a multi-pole selector switch
means 75 is interposed between the contact points 51" of assembly
43 and the 16 electric contacts 78 of the several projection lamps
of the electro-optical reel 24. The multi-pole selector switch
means 75 is adapted to simulate movement of the wiper arm 67" one
or more steps clockwise or counterclockwise without actually
effecting rotation of the wiper assembly 52", and in the form
illustrated in FIG. 5 comprises a set of 16 movable contacts 76
mounted on a multi-pole selector switch bar 77 normally disposed
directly opposite a corresponding set of fixed contact points 78
which connect with the leads from the projector lamp 25 of the
electro-optical reel 24 associated therewith. The set of fixed
contact points 78 also has associated therewith a number of
additional fixed contacts in excess of those corresponding to the
contact points 76. Thus, as shown in FIG. 5, two contact points
78a, 78b are disposed at the left end of the set of contact points
78 and two contact points 78c, 78d are disposed at the right end of
the set of contact points 78. Movement of the multi-pole selector
switch bar 77 one step to the left, as by pivotal movement of the
lever arm 79, will effect movement of the set of flexible contacts
76 as a group to the left so that the extreme left contact point 76
will be electrically connected with the fixed contact 78a and all
of the remaining contact points 76 will be moved one contact to the
left of its normal position. Since fixed contact point 78a is
electrically connected with the electrical lead from the lamps 25
disposed at the extreme opposite end of the set of fixed contacts
78, it will be evident that the movement of the multi-pole selector
switch bar 77 has the effect of rotating the wiper arm 67" one step
in a clockwise direction, when the contact points 51" were arranged
in a circle. Similarily, the multi-pole selector switch bar 77 can
be moved one step to the right to effect apparent movement of the
wiper arm 67" one step counterclockwise. It will also be evident
from FIG. 5 that the multi-pole selector switch bar 77, if desired,
can be moved two steps clockwise or two steps counterclockwise.
The multi-pole selector switch means 75 can be actuated manually by
lever means 79, as schematically illustrated in FIG. 5, or if
preferred can be electrically actuated by a suitable solenoid
mounted within cabinet 10 and connected with the multi-pole
selector switch bar 77. The switch bar 77 is preferably maintained
in a neutral position by a suitable spring biasing means 80.
With the multi-pole selector switch bar 77 held in neutral position
and the wiper arm 67" disposed as shown in FIG. 5 of the drawing,
the combination of symbols which will appear on the electro-optical
reel 24 can be determined by substituting for the selector
apparatus of FIG. 4 the wiper assembly and selector switch means
shown in FIG. 5 of the drawing, since the electro-optical reel 24
has the same structure as electro-optical reel 22 shown in FIG. 4.
It will thus be evident that the switch bar 77 in neutral position
and with wiper arm 67" in the position shown in FIG. 5 the symbols
appearing on reel 24 will be PLUM-BAR-ORANGE. When the switch bar
77 is moved one step to the left in FIG. 5, the symbols appearing
on reel 24 will be BELL-PLUM-BAR, and when switch bar 77 is moved
one step to the right the symbols appearing on reel 24 will be
BAR-ORANGE-CHERRY.
The means for changing a symbol at the end of a play cycle in the
preferred embodiment has operatively associated therewith control
means which normally act to prevent the player changing the symbol
at the end of the play cycle and in the embodiment shown comprises
means for locking the multi-pole selector switch bar 77 in a fixed
position, such as the switch bar locking means 90 shown in FIG. 6.
The control means also has associated therewith means which unlocks
the switch bar 77 and permitting the player to activate the means
for changing the symbol. Preferably a random selector means, such
as selector assembly 44, is placed in the electric circuit of the
switch bar locking means 90 to effect release of the locking means
90 but only on random selected occasions during successive plays of
the apparatus. If desired, however, a manual or coin operated
switch can be associated with the control means in place of a
random selector means.
The random selector assembly 44 which controls the multi-pole
selector switch bar locking means 90 preferably has the same
construction as the selecting and indexing assembly 41 previously
described and comprises a contact plate 45X supported in a fixed
position on the frame 20 through which a drive shaft 30 extends
perpendicular to the plate 45X. A plurality of electrical
conductive rivets or contact points 51X are mounted along a
circular path on the plate 45X at equally spaced intervals. The
wiper assembly 52X is mounted on the drive shaft 30 opposite the
contact points 51X and is constructed the same as the assembly 52.
Only certain of the contact points 51X are electrically connected
with the electrical current lines 73, 74 and the switch bar locking
means 90. The remaining contact points 51X are dummy contacts and
have no electrical connection with the lines 73, 74 and the switch
bar locking means 90.
As shown in the schematic diagram of FIG. 6 an electric signal
light 91 is placed in parallel with the solenoid 92 of the switch
bar locking means 90 and both receive electric current from lines
73, 74 only when the random selector means 45X supplies current
thereto. The electric signal lamp 91 will thus be lighted only when
a selected contact 51X is in electrical contact with the supply
lines 73, 74 (and the solenoid 92 has been activated), thereby
indicating that the switch bar locking pawl 93 is disengaged from
the switch bar 77. The player can move the switch bar 77 to shift
the symbols illuminated in electric reel 24, as above described,
only when the lamp 91 is lighted.
FIG. 7 shows a schematic diagram of the electric circuitry employed
with the selecting and indexing assemblies 41, 42 and 43 and the
associated electro-mechanical elements which control the symbols
displayed by the electro-optical relays 22, 23 and 24 at the end of
each play cycle. The starting switch 100 which connects across
electric current supply lines 101, 102 is activated by the starter
button 16 mounted on the front panel of the cabinet 10. When switch
100 is closed by depressing starter button 16 electromagnet
actuated relays 103, 104, 105 and 106 are activated and close relay
switches 107, 108, 109 and 110 associated with relays 103, 104, 105
and 106, respectively. The relay switches 107, 108, 109 and 110
cause index solenoids 72, 72', 72" and 72X, respectively, to be
activated and draw the indexing pawls 71, 71', 71" and 71X,
respectively, out of engagement with the ratchet wheels 57, 57',
57", 57X of assembly 41 and the corresponding ratchet wheels
associated with assemblies 42, 43 and 44, respectively, and
permitting the drive shaft 30 to rotate the assemblies 52, 52', 52"
and 52X. A switch 106' actuated by relay 106 starts electric motor
32. As the wiper assemblies 52, 52', 52" are rotated, the
electro-optical reels 22, 23, 24 are activated and form in sequence
the selected symbols in the viewing areas 13, 14, 15, respectively.
Diodes 125,126, 127 and 128 are used between the switch 100 and the
relays 103, 104, 105 and 106, respectively, to prevent interaction
between the several relay circuits.
When the starting switch 100 is closed the condensers 119, 120, 121
and 122 in parallel with the relays 103, 104, 105 and 106,
respectively, are charged to the voltage level of the lines 101,
102. The condenser 119 has a lower capacity than condenser 120, the
condenser 120 has a lower capacity than condenser 121, and
condenser 121 has a lower capacity than condenser 122.
When the starter button 16 is released and starter switch 100 is
opened, all the condensers 119, 120, 121 and 122 begin to discharge
through the relay coil associated therewith. As soon as condenser
119 discharges through the coil of the relay 103 to a voltage level
lower than the hold-in voltage of the magnet of the relay 103, the
armature of the relay 103 will drop out, opening the relay switch
107 and causing the indexing pawl 71 to be released and re-engage
the ratchet wheel 57 to hold or "index" the wiper assembly 52 in a
fixed position with the wiper arm 67 engaging one of the contact
points 51, causing a set of three symbols to be "locked" in the
viewing area occupied by electrooptical reel 22. As the voltage in
the remaining condensers 120, 121, 122 drop below their hold-in
voltage, the indexing pawls 71', 71" and 71X, associated with the
wiper assemblies 52', 52" and 52X, respectively, re-engage the
ratchet wheel thereof in pre-determined time-delayed sequential
order after a limited period of free rotation with the indexing
pawl 71X associated with assembly 52X being the last to re-engage
with the ratchet wheel 57X associated therewith. With the indexing
pawls engaging the assembly with which it is operatively
associated, each of the electro-optical reels 22, 23, 24 will
display a set of three vertically arranged symbols in side-by-side
relationship with an adjacent set of three vertically arranged
symbols which together form three horizontal rows containing three
symbols each, with one or more of the horizontal rows comprising a
play combination for the purpose of determining whether a winning
combination has been made. If the selector assembly 44 has been
"indexed" so that wiper arm 67X thereof is in contact with a "live"
electrical contact point 51X effecting release of the multi-pole
selector switch bar 77, the multi-pole selector switch means 75 can
be operated by the player to change the symbols or indicia
displayed by the electro-optical reel 24 in the viewing area 15 of
the cabinet 10, as described heretofore.
In the modified form of the invention shown in FIGS. 8-10 of the
drawing, the amusement apparatus comprises a console-type cabinet
130 with preferably three mechanical reels 131, 131', 131" disposed
in spaced side-by-side relationship rotatably mounted on a
horizontally disposed axles 134, 134', 134" supported by three
spaced vertically disposed support frames or panels 136, 137, 138
secured to the cabinet 130. Each of the reels 131, 131', 131" has a
plurality of symbols or indicia 132 which in the form illustrated
consists of twelve equally spaced symbols formed on the peripheral
surface of each reel and with at least one and preferably three of
the symbols on each of the reels being visible through a viewing
area or window 140 formed in the front panel of the cabinet 130.
Each of the mechanical reels 131, 131', 131" has associated
therewith electro-mechanical reel indexing means 143, 143', 143"
and reel spinning means 150, 150', 150". At least one of the said
mechanical reels also has associated therewith a reel shift means
170 which in the embodiment illustrated is adapted to rotate reel
131 thirty degrees in a clockwise or a counterclockwise direction,
as will be described in detail hereinafter.
Each of the reel indexing means 143, 143', 143" associated with the
reels 131, 131', 131", respectively, preferably comprises ratchet
wheel 144, 144', 144", with twelve uniformly spaced ratchet teeth
corresponding to the number of symbols on the periphery of the
reels 131, 131', 131", respectively. Each of the ratchet wheels
144, 144' and 144" is secured to a supporting rotatable axle 134,
134' and 134", respectively, and each is held in fixed relationship
with the mechanical reel 131, 131', 131", as each reel is also
secured to the rotatable axle 134, 134', 134", respectively. The
ratchet wheel 144 is normally held in a fixed or "indexed" position
by an indexing pawl 146 formed at the upper end of an index lever
arm 145. The lever arm 145 has the lower end thereof pivotally
supported on the peripheral of a rocking wheel 171 associated with
a reel shift means 170 which will be described in detail
hereinafter. The upper end of lever arm 145 has an indexing pawl
146 which is normally held in engagement with the ratchet wheel 144
by spring means 149 and is adapted to be drawn transversely away
from the ratchet wheel 144 by an indexing release solenoid 147, the
piston element of which is connected to the lever arm 145 between
the ends thereof by means of suitable linkage means 148. When the
index release solenoid 147 is activated, the index lever arm 145 is
drawn away from the ratchet wheel 144 a sufficient distance to
disengage index pawl 146 from the ratchet wheel 144, enabling reel
131 to be freely rotated. The reel indexing means 143' and 143"
associated with reels 131' and 131", respectively, have a structure
similar to that of the indexing means 143, except that the lever
arms 145' and 145" are pivotally mounted directly on the support
panels 137, 138, respectively.
The electro-mechanical reel spinning means 150, 150', 151"
associated with reels 131, 131', 131", respectively, are preferably
identical, and reel spinning means 150 is best illustrated in FIG.
8. The spinning means 150 is comprised of a spinning lever arm 151
normally held in a lowered or retracted position out of engagement
with the ratchet wheel 144 by suitable resilient means 152 and by
the fulcrum control means 153 which normally allows the fulcrum 154
of the lower end of the arm 151 to remain in its lowermost position
of vertical adjustment, but which raises the fulcrum 154
sufficiently to allow the transverse pin 155 on the upper end of
the lever arm 151 to engage the wheel 144 when the fulcrum solenoid
156 pivotally moves the outer end of lever member 157 upwardly. The
lever arm 151 is operatively connected with a spin solenoid 158
through the piston element thereof which is connected to the lever
arm 151 by linkage means 159. When the solenoids 156 and 158 are
activated by means of switch means 160 as hereinafter described,
the lever means 157 and linkage means 159 rapidly cause the pin 155
on the upper end of the spinning lever arm 151 to engage the
ratchet wheel 144 and cause the ratchet wheel 144 and reel 131
associated therewith to rotate relatively rapidly in a
counterclockwise direction. The fulcrum solenoid 156 and the spin
solenoid 158 are simultaneously activated by having the indexing
lever arm 145 close a leaf spring switch 162 so disposed that the
switch 162 is closed when the indexing lever arm 145 and panel 146
are moved away from the ratchet wheel 144 a distance sufficient to
permit the reel 131 being freely rotatable.
The reel or symbol display shift means 170 which is included
preferably only in the operating mechanism of reel 131 (but, if
desired, can be included with reels 131' and 131") is adapted to
permit a player to shift rotatably the reel 131 so that one of the
symbols or indicia in the play combination appearing in the viewing
window 140 at the end of the play cycle can be changed by rotatably
shifting the reel 131, at least one step clockwise or one step
counterclockwise in order to improve the value of the play
combination and thereby increasing the player's participation in
the play cycle. The reel shift means 170 shown in operative
association with reel 131 in FIG. 8 comprises a rocker wheel 171
pivotally mounted on the support frame 136 with the wheel 171
having a rocker arm 172 extending downwardly therefrom. The rocker
wheel 171 is normally held in a fixed position by the rocker wheel
locking means, such as the latch means 183. The lower end of
indexing lever arm 145 is pivotally secured to a stud 173 extending
perpendicularly from the surface of the rocker wheel 171 adjacent
the peripheral edge thereof and preferably at a point on a
horizontal diameter line of the rocker wheel 171 when the wheel 171
is held in "neutral" position. When the latch means 183 is out of
locking engagement with the rocker wheel 171 and the pawl 146 in
engagement with the ratchet wheel 144, movement of the rocker wheel
171 clockwise causes the indexing lever arm 145 and panel 146 to be
moved upwardly and rotates the reel 131 one twelfth of a revolution
in a clockwise direction, and when the rocker wheel 171 is moved in
a counterclockwise direction, the index arm 145 and pawl 146 are
moved downwardly, causing the reel 131 to rotate one-twelfth of a
revolution in a counterclockwise direction. The rocker arm 172 is
normally held in a "neutral" or centered position by two equal and
oppositely disposed rocker arm spring means 174, 175. The rocker
wheel 171 is moved in a clockwise or counterclockwise direction by
means of solenoid assemblies 178, 179, respectively. Spring means
180, 180' are provided between the rocker wheel 171 and the
solenoid assemblies 178, 179, respectively, to prevent placing
undue strain on the rocker wheel 171 by the index lever arm 145 and
associated elements in the event solenoids 178 and 179 are
inadvertently activated while the rocker wheel latch means 183 is
in locking engagement with the rocker wheel 171.
As best shown in FIG. 8, the locking means which comprises the
latch means 183 includes a latch pawl 184 which engages a recess
185 formed in the periphery of the rocker wheel 171 and in which
the pawl 184 is normally seated. When the latch solenoid 186 is
activated to withdraw the latch pawl 184 clear of the recess 185 in
the rocker wheel 171, the rocker wheel 171 can be rotatably moved
clockwise or counterclockwise by the solenoid assemblies 178, 179,
respectively, in response to a suitable player actuated switch
control lever mounted on the front surface of the console 130.
While the latch solenoid 186 can be controlled by a player operated
switch which is operated in conjunction with the player activated
means for changing a symbol at the end of each play cycle, it is
preferable that the latch solenoid 186 have operatively associated
therewith control means comprising a random selector means, such as
selector means 44a having the structure described for the selector
assembly means 44 in the embodiment of FIGS. 1-7. The control means
comprising the random selector means 44a in the present embodiment
is placed in the operating electrical circuit of the latch solenoid
186 and permits the latch solenoid 186 effecting withdrawal of pawl
184 and release of the shift means 170 only when the selector means
44a has connected the solenoid 186 with a source of electric
current. If desired, the locking means 183 can be omitted, and the
player activated symbol changing means can be rendered operative
simply by having a random selector means, such as means 44a, placed
in the electric circuit of solenoid assemblies 178, 179. Similarly,
it should be understood that a random selector means, if desired,
can also be placed in the assembly of electrical and/or electronic
elements comprising the player actuated means for changing one of
the images forming the first combination in the previously
described embodiment using electro-optical reels.
Any conventional random selector means can be operatively connected
in the electrical circuit of the latch solenoid 186. The signal
light 187 in parallel with the latch solenoid 186 will be lighted
only when the solenoid 186 has been activated to release the latch
means 183 holds, thereby indicating that the drum or reel rotating
means for changing one of the symbols of the combination can be
operated by the player at the end of the play cycle.
FIG. 10 of the drawing shows a schematic diagram of the electric
circuitry associated with the modified form of the apparatus shown
in FIGS. 8-9. Thus, when the starter switch 185 which connects
across electric lines 186, 187 is closed by depressing a starter
button (not shown) mounted on the surface of an upper panel of the
cabinet 130, the solenoid actuated relays 188, 189, 190 are closed
and which in turn close relay switches 191, 192, 193, respectively.
The closing of relay switches 191, 192, 193 activates the indexing
release solenoids 147, 147', 147", causing lever arms 145, 145',
145" and index pawls 146, 146', 146" to be withdrawn from ratchet
wheels 144, 144', 144" and effect closing spin switches 162, 162',
162", respectively, which activates the solenoid 156, 156', 156"
and 158, 158', 158", respectively; whereby the reels 131, 131' and
131" are rotated.
When solenoid relays 188, 189, 190 are closed, the condensers 194,
195 and 196, respectively, are charged to the voltage level which
exists between the lines 201, 202. Condenser 196 has a smaller
capacity than condenser 195 and condenser 195 has a smaller
capacity than condenser 194. Diodes 197, 198, 199 are used between
starter switch 185 and relays 188, 189, 190, respectively, to
prevent interference between the respective relay circuits.
When the starter button is released so that starter switch 185
opens, the condensers 194, 195, 196 commence to discharge through
the coils of relays 188, 189, 190, respectively, and as soon as a
voltage level lower than the hold-in voltage of the respective
relays 188, 189, 190 is reached, the relay switches 191, 192, 193
open, allowing the indexing solenoid 147, 147', 147" controlled
thereby to be de-energized, and allowing the index pawls 146, 146',
146" associated therewith to re-engage the ratchet wheel 144, 144',
144", respectively, and index the reels 131, 131', 131". It will be
evident that the reel 131" associated with index solenoid 147" and
condenser 196 will be indexed first, followed in short succession
by reel 131' which is associated with index solenoid 147' and
condenser 195, and finally reel 131 associated with index solenoid
147 and condenser 194 will be indexed last. When all of the reels
131, 131', 131" have been indexed, each of the reels is so disposed
in the viewing window 140 to display preferably a set of three
vertically arranged symbols in side-by-side relationship which form
three horizontal rows with one or more of the horizontal rows
comprising a play combination for the purpose of determining
whether a wining combination has been made.
If the rocker wheel latch means 183 associated with reel 131 has
been activated, as by a manually operated switch or by a random
selector means of the type previously described, the latch solenoid
186 will be activated and release the rocker wheel 171, permitting
stepwise rotatable movement thereof in a clockwise or
counterclockwise direction when the operator operates a switch
means 200, such as a dipole switch, to electrically activate either
solenoid 178 or 179 to effect movement of the rocker wheel 171 and
the index lever arm 145 associated therewith, either upwardly or
downwardly, respectively, one-twelfth of a revolution so as to
change the symbols displayed by the reel 131 in the viewing window
140.
While the foregoing embodiments of the present invention employ
electro-mechanical means to effect displaying the sequence of
symbols and stopping the sequential change of symbols or "indexing"
of the symbol display means to form in the viewing area the various
visible combinations of symbols or indicia some of which are
designated as being winning combinations having a predetermined
value and also employ electro-mechanical means for shifting certain
of the symbols visible in the viewing area of the apparatus at the
end of the play cycle, it will be understood by those skilled in
the electronic art that the foregoing operations with the
electrooptical reel can be performed entirely by electronic means.
Thus, for example, the various symbols appearing in the viewing
area of the amusement apparatus of the present invention can be
formed by projecting onto a read-out screen of an electronic reel
controlled by an integrated circuit which is fully transistorized
to provide the desired combinations of symbols without the use of
any moving parts. The means for shifting one or more of the symbols
appearing in the viewing window of the amusement apparatus at the
end of each play cycle will, however, always be controlled by a
player actuating a control lever or buttons which will, if not
temporarily inactivated by a random selector means, produce the
desired shift or change of at least one of the symbols preferably
at the end of the play cycle in order to produce a new winning
combination or one having a higher value.
It should also be understood that the symbol changing means with
which the control lever or button actuated by the player is
operatively associated can be a mechanical or electro-mechanical
combination or an electric or electronic circuit which functions
when actuated by a player to change at least one of the symbols of
the play combination formed in the viewing area on at least random
selected occasions during a series of plays of the apparatus.
