Gaming device with multiple spinning wheels and method
Abstract
The specification discloses a multi-wheel game-of-chance having
at least two groups of spinning wheels, wherein each group includes
at least two concentric spinning wheels having a viewable surface
face thereon. A plurality of indicia are positioned on the
peripheral of the viewable surface face of each wheel such that all
indicia on each wheel is viewable to the user. Bet areas are
positioned at various locations around at least a portion of each
group of wheels; along a line joining the center of any two groups
of wheels; and/or a junction between various radially positioned
lines extending from the center of two or more groups of wheels.
Each bet area represents a possible payline with various pay ratios
depending on the probability of various predetermined combinations.
For instance, a one-group combination payline has the lowest pay
ratio; a two-group payline requires the combination from two groups
of wheels and thus, has a higher pay ratio than a one-group
payline; and as additional group combination paylines are added,
the higher the pay ratio can become.

Description
FIELD OF THE INVENTION
This invention relates to devices and methods for playing games.
More specifically, this invention relates to a device and method
for playing a game of chance wherein indicia on a plurality of
spinning wheels or representations of wheels are combined along one
or more pay lines to produce a game outcome.
BACKGROUND
The gaming industry has long been trying to develop gaming devices
that are more exciting and enjoyable to play. When gaming devices
are more exciting and enjoyable, they tend to be played more by
players and they tend to generate more revenue for the gaming
device operator or provider.
For example, spinning reel gaming devices are well known in the
prior art and have long been a staple of the gaming industry. These
games utilize one or more actual or apparent cylindrical reels that
spin around an axis in response to the player's activation of the
game. Game symbols are displayed on the outer circumference of the
reels. Typically, the game is won and a prize is awarded when the
game symbols on the reels provide a particular predetermined
outcome shown when the reels stop spinning. As a result, a
three-wheel game might provide a large award to the player if the
outcome is three bars in a row displayed by the three co-axial and
adjacent reels, as viewed by the player.
For wagering game tables, however, there have been much fewer
tables that utilize spinning reels. One such example that has
become well known in the industry is roulette. Roulette uses a
wagering mat and a single separated spinning reel having a
plurality of numbered receiving channels positioned peripherally
around the center of the reel. Players place wagers on the wagering
mat at one or more positions, wherein each position has a
predetermined pay ratio depending on the probability of winning.
The dealer then places a ball on an upper inwardly-angled edge of
the reel and the reel is spun. As the reel slows and the
centrifugal force on the ball becomes less than the gravitational
force, the ball rolls toward the center of the reel and is captured
in one of the numbered receiving channels, thereby indicating the
winning wagers, if any.
These spinning reel games can be made more exciting to the player,
and thus more likely to be played, by addition of features such as
flashing lights, sounds, double bonus time-periods, and progressive
linking of multiple such games to a common jackpot in addition to
the local jackpot for each machine on its own. These methods of
making spinning reel games more exciting and more utilized are well
known in the art. However, they still present the game player with
only a limited number of winning combinations.
With regard to roulette or spinning wheel games in the prior art,
they typically also have the wheels mounted at their axial center
on axial drive shafts. Mounting and rotating the wheel on an axial
drive places significant stress on the drive shaft and associated
drive and support structure. Also, an axial mount and drive
mechanism is typically noisy and easily damaged or moved off-center
during use or installation or movement of the game apparatus. Axial
mounting also occupies significant space for the axial drive behind
the wheel, and it requires significant additional and complicated
structure in order to drive multiple concentric wheels
independently.
One of the disadvantages of spinning reel gaming devices is that
they only allow a player to see a small number of game symbols on
the reels. Because of the physical curvature of a reel, it is
generally only possible for a view of the symbols of on a reel to
be within a players view. This is not the case with wheels. Wheels
may have annular surfaces around the entire circumference of a
wheel. Therefore, wheels can display a greater number of symbols
than reels.
BRIEF SUMMARY OF THE INVENTION
The present invention comprises a wagering device that includes at
least two groups of spinning wheels, wherein each group includes at
least two concentric spinning wheels having a viewable surface face
thereon. A plurality of indicia are positioned on the periphery of
the viewable surface face of each wheel such that all indicia on
each wheel is viewable to the user. Bet areas are positioned at
various locations around at least a portion of each group of
wheels; along a line joining the center of any two groups of
wheels; and/or a junction between various radially positioned lines
extending from the center of two or more groups of wheels. Each bet
area represents a possible pay line with various pay ratios. For
instance, a bet area directly outside a single group of wheels has
the lowest pay ratio since only the indicia in line with the wheels
of that group and the bet area must match a predetermined winning
combination. A bet area along a pay line joining the center of two
groups of wheels requires a predetermined winning combination
indicia on all wheels in both groups and thus, has a higher pay
ratio than a single wheel group pay line. A bet area that is a
junction between three center lines, for example, of three groups
of wheels would have an even higher pay ratio due to the lower
probability associated with the predetermined winning combination
needed from all three wheels in all three groups.
There are many other aspects of the invention that are apparent
from this. For example, any combination of two or more groups of
wheels may be utilized. In addition, any number of two or more
wheels may be utilized in each group. As another example, in the
preferred embodiment, three groups of wheels, each group having
three concentric wheels, are evenly positioned in a generally
clover formation such that the two-group pay lines joining the
center of each group form a generally isosceles triangle, and
wherein the highest three-group combination bet area is generally
formed at the center of the isosceles triangle with pay lines
extending to the center of each group.
ADVANTAGES OF THE INVENTION
It is therefore an advantage of the present invention to provide a
game-of-chance apparatus and method that is more exciting for the
player and thus more likely to be played.
It is another advantage of the present invention is that it allows
players to place wagers on many different outcomes of a single
game.
It is another advantage of the present invention to provide a
table-wagering game that is utilized more than prior art games and
thus generates more revenue and profits for the game owner and
gaming establishment.
It is another advantage of the present invention to provide a
"spinning reel" look and feel for a game that is utilized more than
prior art games and thus generates more revenue and profits for the
game owner and gaming establishment.
Yet another advantage is to provide a table-wagering game that can
be played with a multitude of players and with or without a live
operator.
Yet another advantage is to provide a "slot machine" type of game,
thus allowing the game to be played at any time by one player and
without any help from any other player or operator.
Yet another advantage of the present invention is that it provides
a wagering game-of-chance apparatus having a plurality of spinning
wheels grouped in a plurality of groups thereby providing a
multitude of wagering opportunities and pay lines and, thus a
multitude of possible winning combinations.
A still further advantage is that the invention provides such a
game in which the multiple wheels are concentric and preferably
rotate or stop rotation in sequence.
A further advantage is that the invention provides a multi-wheeled
game that is quieter and more durable and long lasting than prior
multi-wheeled games. A related advantage is providing such a game
with a more precise yet relatively simple drive mechanism for
driving independent rotation of the wheels. A still further related
advantage is providing such multi-wheeled game with resilient and
reliable radial drive gears. Another advantage is providing a
multi-wheeled game in which the wheel drive need not occupy as much
space as conventional axial drive wheel games.
A further advantage of the present invention is that it provides a
multi-wheeled game apparatus and method in which the multiple
wheels can all be viewed by the player without moving from place to
place and, preferably, are all mounted together in a manner that
occupies approximately the same floor space as a traditional,
single game slot machine or table game.
There are other advantages of the present invention. They will
become apparent as the specification proceeds.
In this regard, it is to be understood that the scope of the
present invention is to be determined by reference to the
accompanying claims, and not necessarily by whether any given
embodiment achieves all of the objects or advantages stated
herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In the following detailed description of the preferred embodiments,
reference is made to the accompanying drawings, which form a part
of this application. The drawings show, by way of illustration,
specific embodiments in which the invention may be practiced. It is
to be understood that other embodiments may be utilized and
structural changes may be made without departing from the scope of
the present invention.
Referring now to FIGS. 1-3, the preferred embodiment, generally
indicated by reference number 10, comprises a gaming device having
generally an upper playing area 220 and a lower support base 280.
The upper playing area 220 is defined by a playing surface 228
having a first lobe 222, a second lobe 224 and a third lobe 226,
which together generally form a clover shape. However, it is
recognized that many other shapes may be used. A ridge 230 may be
provided that extends upward from and on the peripheral of the
playing surface 228.
Positioned generally at the center of the playing surface 228 in an
approximate clover positioning are preferably three groups 240,
260, and 280 of concentric wheels. The first group 240 is
preferably positioned at least partially within the first lobe 222;
the second group 260 is preferably positioned at least partially
within the second lobe 224; and the third group 280 is preferably
positioned at least partially within the third lobe 226. Each group
240, 260 and 280 are preferably equally spaced apart such that a
line drawn connecting the centers of each group 240, 260, and 280
forms an isosceles triangle. The present invention is intended to
encompass a fewer number of groups and wheels. For example, only
two groups of wheels may be used or only two non-concentric wheels
may be used and still be within the present invention. Furthermore,
the overall configuration of gaming device 10 may be different and
still be within the present invention. For example, groups one or
more of groups 240, 260, and 280 may be in a vertical position
instead of a horizontal position. The present invention is also
intended to encompass non-mechanical wheels. Wheels can be
represented by electronic display devices, such as a video screen
or lights.
In the preferred embodiment, each group 240, 260, and 280 comprises
three concentric wheels, each having a visible annular surface
positioned upward from the playing surface 228. More specifically,
the first group 240 preferably comprises a first wheel 242, a
second wheel 244 and a third wheel 246, wherein the visible annular
surface of the first wheel 242 has a larger diameter than the
visible annular surface of the second wheel 244, and wherein the
visible annular surface of the second wheel 244 has a larger
diameter than the visible annular surface of the third wheel 246
such that the visible annular surfaces on all three wheels 242, 244
and 246 can be seen by a player.
Similar to the first group 240, the second group 260 preferably
comprises a first wheel 262, a second wheel 264 and a third wheel
266, wherein the visible annular surface of the first wheel 262 has
a larger diameter than visible annular surface of the second wheel
264, and wherein the visible annular surface of the second wheel
264 has a larger diameter than the visible annular surface of the
third wheel 266 such that the visible annular surfaces on all three
wheels 262, 264 and 266 can be seen by a player.
Similar to the first group 240 and the second group 260, the third
group 280 preferably comprises a first wheel 282, a second wheel
284 and a third wheel 286, wherein the visible annular surface of
the first wheel 282 has a larger diameter than the visible annular
surface of the second wheel 284, and wherein the visible annular
surface of the second wheel 284 has a larger diameter than the
visible annular surface of the third wheel 286 such that the
visible annular surfaces on all three wheels 282, 284 and 286 can
be seen by a player.
Now referring to FIG. 3, various symbols or indicia 19, which
together can form various winning combinations, are provided at
spaced-apart radial positions on the visible annular surfaces of
each wheel 242, 244, 246, 262, 264, 266, 282, 284, and 286. A
plurality of wager locations 290, 292, 294, 300, 302, 304 and 320
corresponding to various pay lines are positioned on the playing
surface 228 proximal to the wheel groups 240, 260, and 280, wherein
wager locations 290, 292 and 294 are single group wagers; wager
locations 300, 302 and 304 are double group wagers; and wager
location 320 is a triple group wager. More specifically, wager
locations 290 are positioned at least partially around the
peripheral of first group 240; wager locations 292 are positioned
at least partially around the peripheral of second group 260; and
wager locations 294 are positioned at least partially around the
peripheral of second group 240. A single group wager on the first
group 240 is won when predetermined symbols or indicia line up
along the respective pay line on the first wheel 242, the second
wheel 244 and the third wheel 246 are combined to match a
predetermined winning combination. A single group wager on the
second group 260 is won when predetermined symbols or indicia line
up along the respective pay line on the first wheel 262, the second
wheel 264 and the third wheel 266 are combined to match a
predetermined winning combination. A single group wager on the
third group 280 is won when predetermined symbols or indicia 19
line up along the respective pay line on the first wheel 282, the
second wheel 284 and the third wheel 286 are combined to match a
predetermined winning combination.
Double group wager locations 300, 302, and 304 require a winning
combination from two of the three group. For instance, wager
location 300 is positioned between first group 240 and second group
260 such that symbols or indicia 19 along pay line 300a of wheels
242, 244, and 246 and pay line 300b of wheels 262, 264, and 266
must match a predetermined winning combination in order for wager
location 300 to be a winning location. Similarly, wager location
302 is positioned between second group 260 and third group 280 such
that symbols or indicia 19 along pay line 302a of wheels 262, 264,
and 266 and pay line 302b of wheels 282, 284, and 286 must match a
predetermined winning combination in order for wager location 302
to be a winning location. Similarly, wager location 304 is
positioned between third group 280 and first group 240 such that
symbols or indicia 19 along pay line 304a of wheels 282, 284 and
286 and pay line 304b of wheels 242, 244, and 246 must match a
predetermined winning combination in order for wager location 304
to be a winning location.
Triple group wager location 320 is preferably positioned equally
spaced between the first group 240, the second group 260 and the
third group 280. Pay lines 320a, 320b and 320c extend from the
wager location 320 to the center of first group 240, second group
260 and third group 280, respectively, and as such, a winning
combination requires a matching combination from all nine wheels
242, 244, 246, 262, 264, 266, 282, 284, and 288 along the
respective pay lines 320a, 320b, and 320c. Because a triple group
winning combination has the lowest probability, a triple group
wager has the highest pay ratio, and, conversely, a single group
wager has the lowest pay ratio.
As seen in FIG. 13, the present invention comprises an embodiment
that utilizes only two wheels. In this embodiment, wheels 502 and
504 are adjacent to each other an at least one pay line is
provided. Pay line 506 may be similar to pay lines 300, 302, and
304 shown in FIG. 3. However, in this embodiment, only two wheels
are used. Wheels 502 and 504 do not contain concentric groups. Pay
lines 508, 510, and 512 are symmetrical combinations of radial pay
lines. Non-symmetrical combinations of radial pay lines may also be
provided, such as pay line 514.
FIG. 14 illustrates linear and non-linear radial pay lines for a
group of concentric wheels. In this embodiment, at least two wheels
are provided, 520 and 522. Pay line 524 radiates linearly outward
while pay lines 526 and 528 radiate non-linearly outward. Linear
and non-linear radial pay lines may be combined with other types of
pay lines with other wheels.
FIG. 15 discloses an embodiment that utilizes three single wheels
(no groups of concentric wheels). In this embodiment, the pay lines
are similar to the those disclosed in FIG. 3. Bet positions 530
correspond to single pay lines, bet positions 532 correspond to
double pay lines, and bet positions 534 correspond to triple pay
lines.
FIG. 16 represents an example of a pay table that may be used with
the embodiment disclosed in FIG. 15. For example, if a player
placed a wager on a double pay line (532) and the positions on the
pay line contained double bars (after the wheels had been spun),
the player would be paid 4 credits.
FIG. 17 illustrates an embodiment that utilizes V-shaped pay lines
340. V-shaped pay lines 340 combine two or more symbols from
different wheels.
FIG. 18 illustrates an embodiment that utilizes rectangular pay
lines 350. Rectangular pay lines 350 also combine two or more
symbols from different wheels.
FIG. 19 illustrates an embodiment that utilizes single wheel
V-shaped pay lines 360. In this embodiment, pay lines 360 combine
two or more symbols on the same wheel.
Now referring to FIG. 11a, in the preferred manual form, a dealer
tends the bets and activates the wheels. The wheels are stopped in
wheel stopping positions. The stopping positions may be determined
in a number of ways that are well known in the art. For example, a
computer may be provided that randomly generates numbers. When a
number is generated, it it is compared with a wheel stopping
position table that contains all of the possible stopping positions
for all of the wheels. The wheels are then stopped in the positions
that correspond to the random number selected by the computer.
Alternatively, a random number may be generated for each wheel and
the stopping position of each wheel may be independently
determined. The dealer then evaluates the wins based on the
combination of symbols or indicia 19 and rewards the player(s)
accordingly.

accordingly.
With continuing reference to FIG. 11b, a microprocessor controller
may evaluate the combination of symbols or indicia 19 and award
prizes to player(s) accordingly. Various pay ratios can be
utilized; for exemplary purposes only, a 1:1 pay ratio can be
utilized for a single group winning combination, a 3:1 pay ratio
can be utilized for a two group winning combination, and a 10:1 pay
ratio can be utilized for a three group winning combination.
Each group 240, 260 and 280 is preferably rotated by a separate
drive mechanism that spins each wheel of each group and stops each
wheel of each group in a position determined by a controller. As
each driving mechanism is identical for each group 240, 260 and
280, only the driving mechanism for the first group 240 is herein
described in detail. Referring jointly to FIGS. 4 and 5, the
periphery of each of the wheels 242, 244 and 246 is provided with
gear teeth 31. The wheels 242, 244, and 246 are positioned,
supported and driven by a compact and simple mechanism that
includes three gear sets 32a, 32b, and 32c, which engage the gear
teeth 31. The gear sets 32a, 32b, and 32c are situated adjacent to
the peripheral region of the wheels 242, 244, and 246 and are
angularly spaced apart relative to the axis of rotation 16 of the
wheels. The angular interval between the gear sets 32a, 32b, and
32c around the axis of rotation 16 is less than 180 degrees for
reasons that will hereinafter be discussed, and is preferably 120
degrees as in this particular example of the invention.
A pair of spaced apart circular support plates, including a forward
support plate 33 and rear support plate 34, extend vertically
behind the wheels 242, 244, and 246. Bolts 35 secure the two
support plates together. Referring jointly to FIGS. 4 and 6, each
of the gear sets 32a, 32b, and 32c has a rotatable drive shaft 36
which extends from a back end bearing 37 mounted in the rear
support plate 34 through a bushing 38 mounted in the forward
support plate 33 to a front end bearing 39 mounted in an annular
front structural member 41. The drive shaft 36 of each gear set
32a, 32b, and 32c is driven by a separate one of three electric
motors 42a, 42b and 42c which are situated behind the rear support
plate 34 and secured to that support plate. Each such motor 42a,
42b, and 42c turns a motor output gear 43 situated between the
forward and rear support plates 33 and 34 and which engages a
smaller driven gear 44 situated on the drive shaft 36 of the
associated one of the gear sets 32a, 32b, and 32c at a location
between the support plates. The drive shafts 36 are constrained to
rotate with the driven gears 44 in this example by keys 46 within
the driven gears that sent in longitudinal keyway slots 47 that
extend along each drive shaft. Alternately, the driven gears 44 may
be locked to the drive shafts 36 by setscrews or other means known
to the art.
Referring to FIGS. 6, 7 and 8 in conjunction, each of the gear sets
32a, 32b and 32c has three wheel support gears disposed along the
drive shaft 36 including a front support gear 48, an intermediate
support gear 49 and a rear support gear 51. The front support gear
48 engages the teeth 31 of the first wheel 242, intermediate
support gear 49 engages the teeth 31 of the second wheel 244, and
the rear support gear 51 engages the teeth 31 of the third wheel
246. The support gears 48, 49, and 51 are of equal outer diameter
in this example of the invention and are proportioned to abut
against each other. A tubular sleeve 52 is disposed on each drive
shaft 36 in coaxial relationship therewith and extends between
bushing 38 and the rear support gear 51 to hold the support gears
at the locations along the shaft at which they engage the wheels
242, 244, and 246.
Provided that the angular interval between successive ones of the
three gear sets 32a, 32b, and 32c around the axis of rotation of
the wheels 242, 244, and 246 is less than 180 degrees as previously
described, the support gears 48, 49, and 51 act to hold each of the
wheels in a centered relationship relative to the axis of rotation.
The gear sets 32a, 32b, and 32c also function to rotate each of the
wheels 242, 244, and 246. In particular as shown in FIG. 6, at gear
set 32a the front support gear 48 is constrained to rotate with
drive shaft 36 by an internal key 53 which seats in the drive shaft
keyway slot 47. The other two support gears 49 and 51 at gear set
32a are idler gears that are free to rotate relative to the drive
shaft 36. Thus, the first gear set 32a both supports and drives the
first wheel 242 while serving only as a support for the other
wheels 244 and 246.
At the second gear set 32b, as shown in FIG. 5, it is the
intermediate support gear 49 that is constrained to rotate with
drive shaft 36 by an internal key 53 while the front and rear
support gears 48 and 51 are idler gears that may turn relative to
the shaft. Thus, the second gear set 32b drives the second wheel
244 while also serving as a support for the other two wheels 242
and 246.
With reference to FIG. 8, at the third gear set 32c the rear
support gear 51 is constrained to rotate with drive shaft 36 by an
internal key 53 with the front and intermediate support gears 48
and 49 being free turning relative to the shaft. Accordingly, the
third gear set drives the third wheel 246 while functioning as a
support for the other two wheels 242 and 244.
Referring again to FIGS. 4 and 5, the wheels, wheel support, and
drive mechanism are utilized by connectors 35 that extend from the
annular front structural member 41 to the circular front support
plate 33 and the assembly has a maximum diameter that enables
insertion and withdrawal of the unitized mechanism through the
opening 22. This facilitates assembly and repairing of the slot
machine. The utilized mechanism is positioned at its back end by a
support bracket 50 that extends from rear support plate 34 into a
socket 55 that is secured to the rear wall of cabinet 21.
With continued reference to FIGS. 4 and 5, the wheel drive motors
42a, 42b, and 42c are preferably controlled by a microprocessor
circuit, contained within a circuit housing 54, which maybe of the
known design that is commonly used in conventional modern gaming
devices. The motors 42a, 42b, and 42c are brake gear motors of the
known stepping form which separately rotate each wheel 242, 244,
and 246 through a predetermined number of angular increments that
is determined by the control circuitry and which varies during
successive games. Referring again to FIG. 2, the angular increment
through which each wheel 242, 244, and 246 is traveled during each
step of the rotary movement corresponds to the angular spacing of
the centers of successive ones of the indicia 19 about the axis of
rotation of the wheels. Thus, indicia 19 of each wheel 242, 244 and
246 are in alignment along radii of the axis of rotation when the
motors stop turning the wheels. The presence of particular indicia
19 or combinations of indicia at a pay line at that time determines
the player's winnings or score in the conventional manner.
Motor control circuits 54 which are microprocessor controlled
require tracking of the rotary movement of the indicia carrying
rotatable members by the microprocessor 56. For this purpose,
tracking means 57 are provided for generating repetitive electrical
signal pulses including first, second and third series of pulses
each of which is indicative of rotary motion of a separate one of
the wheels 242, 244 and 246. Successive pulses in each series are
produced in response to successive increments of rotary motion of
the wheel 242, 244, and 246 that is being tracked by the particular
series. In a manner known to the art, this enables the
microprocessor 56 to cause stopping of rotation of the members at
times when indicia are in alignment at the pay line and, by
counting the pulses, to determine which indicia are at the pay
line.
The tracking means 57 of this example of the invention operates by
photoelectric sensing of wheel motion. Means 57 includes a bracket
58 that extends forward from the front circular support plate 33,
past the peripheries of each of the wheels 242, 244, and 246, and
into the front structural member 41. Bracket 58 has pairs of spaced
apart tangs 59 and the tangs of each pair extend along opposite
sides of the gear teeth 31 of a separate one of wheels 242, 244,
and 246. One tang 59 of each pair supports a small light source 61
positioned to direct light towards a light detector 62 supported by
the other tang of the pair and which is at the other side of the
gear teeth 31 of the wheels 242, 244, and 246 which extends between
the pair of tangs. The light sources 61 may be of any of a variety
of types such as light emitting diodes for example. The light
detectors 62 may also be of any of a variety of different types,
phototransistors and photodiodes being examples.
The gear teeth 31 of each wheel 242, 244, and 246 repetitively pass
through the light path between the associated light source 61 and
light detector 62. This causes the output signal of the detector 62
to switch repetitively between a high condition and a low condition
thereby providing the desired series of rotary motion tracking
signal pulses. For reasons to be hereinafter described, the wheels
242, 244 and 246 in their preferred form are made of translucent
material. In instances where this results in an undesirably small
variation of the light detector 62 outputs in response to the
passage of gear teeth 31, the sides of the gear teeth can be coated
with paint or other opaque material. It is also possible to situate
the light sources 61 and detectors 62 at locations that are closer
to the axis of rotation than the peripheral gear teeth 31. The
wheels 242, 244 and 246 may then be provided with bands of light
passages separated by relatively opaque areas that travel between
the light sources 61 and light detectors 62 as the wheels turn.
Movement of the wheels 242, 244, and 246 in a direction parallel to
the axis of rotation 16 is prevented by pads 63 that are secured to
the ends of the tangs 59 of bracket 58. The pads 63 are preferably
formed of a low friction resilient material such as felt. The pads
63 at each pair of tangs 59 extend towards and bear against the
sides of the wheels 242, 244 and 246 that extends between that pair
of tangs. A pair of similar brackets 58a and 58b having pads 63
extend from the front circular support plate 33 to restrain axial
movement of the wheels 242, 244 and 246 at additional locations
which are angularly spaced apart around the axis of rotation 16 of
the wheels. The brackets 58, 58a, and 58b of this particular
example of the invention are at 120 degree angular intervals around
the axis of rotation 16.
The example of the invention described above with reference to
FIGS. 1 to 8 embodies a highly advantageous mechanism for
supporting and driving the indicia carrying rotatable wheels 242,
244 and 246. Both functions, supporting and driving, are effected
with simple gear sets situated at the periphery of the disks. This
eliminates the complex and bulky telescoped shafting and other
components at the axis of rotation of the wheels that has
heretofore been present in gaming devices of this general type. The
rim drive also makes it possible to include open centered rotating
wheels which need not extend to the axis of rotation thereby
enabling viewing of indicia bands of progressively smaller diameter
that are spaced apart along the axis of rotation of the wheels. The
wheel support and drive mechanism in the preferred form is easily
removable from the slot machine cabinet as a unit to facilitate
repairs.
While the rim driven construction discussed above constitutes the
preferred form of the invention, certain novel features of the
previously described embodiment can advantageously be embodied in
multi-wheel machines that have center shafting for the purpose of
supporting and driving the wheels. This includes, for example,
axial spacing of the rotating bands of indicia to provide a three
dimensional aspect to the indicia array as viewed by the player.
Referring jointly to FIGS. 9 and 10, the wheels 242a, 244a, and
246a of this embodiment are flat circular plates that are spaced
apart along a common axis of rotation 16a. The wheels 242a, 244a,
and 246a have progressively greater outside diameters thereby
enabling viewing of an annular region 17a of the front surface of
each of the disks by a player who situated in front of the slot
machine that regions are at the radially outermost portions of the
disks. Annular bands of indicia 19a of the previously described
kind are imprinted on the regions 17a of the wheels. An interesting
effect is created if the annular regions 17a of the wheels 242a,
244a, and 246a are beveled surfaces so that the indicia 19a of the
three wheels are in a coplanar or near coplanar relationship.
Wheels 242a, 244a, and 246a are supported and separately rotated by
a drive system 69 that includes three coaxial drive shafts 71, 72
and 73 of progressively shorter length. The back end of the inner
drive shaft 71 extends out of intermediate drive shaft 72 and is
supported by a first bearing 74 that is secured to one arm 76 of
internal framing 77 within the slot machine cabinet 21a. The front
end of inner drive shaft 71 also extends out of the intermediate
drive shaft 72 and has a flange 79 seated in a conforming opening
in a circular cap 81 that is in front of the first wheel 242a.
Screws 82 extend through the front disk 13a and cap 81 and engage
in flange 79 thereby constraining the wheel to rotate with the
inner drive shaft.
A second bearing 83, supported by another framing arm 84, supports
the intermediate drive shaft 72 at a location that is forward from
the back end of the drive shaft 72. A flange 86 at the front end of
the intermediate drive shaft 72 seats in a conforming opening in
the second wheel 244a and is secured to that disk by additional
screws 87. The outer drive shaft 73 is supported at an intermediate
location along the drive shaft by a third bearing 88 that is
secured to another arm 89 of the cabinet framing 77. A flange 91 at
the front end of the outer drive shaft 73 seats in a conforming
opening in the third wheel 246a and screws 92 secure the wheel 246a
to the flange.
First wheel 242a, second wheel 244a and third wheel 246a are driven
by separate electrical motors 93a, 93b and 93c respectively, motor
93c being behind motor 93b as seen in FIG. 9. The motors 93a, 93b,
and 93c are secured to brackets 94 which extend from framing 77.
Referring again to FIGS. 9 and 10 in conjunction, motor 51 is
coupled to the inner drive shaft 71 by a drive belt 96 which
engages a pulley 97 that is keyed to the inner drive shaft at a
location adjacent to bearing 74. Another drive belt 98 couples
motor 93b to the intermediate drive shaft 72 by engaging another
pulley 99 that is keyed to the intermediate drive shaft at a
location that is between bearings 74 and 83. An annular collar 101
on intermediate drive shaft 72 extends between pulley 99 and
bearing 83 to prevent movement of the pulley along the shaft. The
third motor 93c is coupled to outer drive shaft 73 by a third drive
belt 102 which engages another pulley 103 that is keyed to the
outer drive shaft at a location immediately behind the third
bearing 88. Another annular collar 104 is adjacent to pulley 103
and is held in place by a setscrew 106 to prevent axial movement of
the pulley along the shaft. Drive belts 96, 98 and 102 are
preferably of the non-slip type which have teeth 107 that engage
conforming grooves in the pulleys on which they are engaged.
Motors 93a, 93b, and 93c are brake gear motors of the stepping type
similar to those of the previously described embodiment of the
invention and function in a similar manner to rotate each wheel
242a, 244a, and 246a through a predetermined number of angular
increments that is determined by the control circuit 54a.
Three circular timer plates 108, 109, and 111 enable microprocessor
tracking of the rotary movement of the wheels 242a, 244a, and 246a
in the previously described manner. Timer plate 108 is disposed in
coaxial relationship with inner drive shaft 71 at a location
between pulleys 97 and 99 and is secured to an adjacent annular
collar 112 that is constrained to rotate with the inner drive shaft
by a setscrew 113. Timer plate 109 is disposed on intermediate
drive shaft 73 in coaxial relationship therewith at a location
between timer plate 108 and pulley 99 and is secured to another
annular collar 114 that is constrained to rotate with the
intermediate drive shaft by another setscrew 116. The third timer
plate 111 is situated between pulley 103 and bearing 83, in coaxial
relationship with the outer drive shaft 73, and is constrained to
rotate therewith by another annular collar 117.
The circular rim of each of the timer plates 108, 109, and 111 is
indented by a series of notches 118 which have an angular spacing
relative to the axis of rotation that corresponds to the
hereinbefore described angular increment of rotary motion of the
wheels 242a, 244a, and 246a. A separate one of three photoelectric
sensors 119 is disposed at the rim of each timer plate 108, 109 and
111 and may be of one of the known types which have a small light
source 121 such as a light emitting diode for example and a light
detector 122 such as a phototransistor for example that produces an
electrical signal in response to light from the source. The light
sources 121 and detectors 122 are at opposite sides of the rims of
the timer plates 108, 109 and 111 at which notches 118 are located
thereby causing light to be transmitted from the sources 121 to the
detectors 122 each time that a notch passes between the two. Thus,
each sensor transmits an electrical pulse to the control circuit
housing 54a each time that the associated timer plate 108, 109 or
111 is stepped through the above described angular increment of
motion by the associated drive motor 93a, 93b, or 93c. As
previously described, this enables the microprocessor 56a to cause
stopping of the rotation of the wheels 242a, 244a, and 246a at
times when indicia are in alignment at the pay line and, by
counting the pulses, to determine which indicia are at the pay
line.
Components of the embodiment illustrated by FIGS. 9 and 10 that are
not depicted therein may be similar to those of the previously
described embodiment of the invention.
FIG. 12 illustrates a networked system 200 of the present invention
in which a single separate display unit 202 containing a plurality
of wheels may be linked to one or more game devices 204. Game
devices 204 may contain any of a large variety of games arid game
displays. Each game device 404 is linked to display unit 202 by a
communication device 206. Communication device 406 may use many
different communication protocols and systems, such as Ethernet
communication protocols, network cards, and cables.
In this embodiment, adjustments may be made to the method of the
present invention to allow a plurality of game devices 204 to use a
single display unit 202. When one of the game devices 204 produces
a wheel spinning event, a signal is transmitted to display unit
202. If display unit 202 is currently working to generate a display
for another wheel spinning event, the signal or information in the
signal may be placed in a queue or memory device. When display unit
204 is free to respond to a new wheel spinning event, the signal is
received, processed, and display unit 204 spins the wheels. The
method would then continue as previously discussed.
In order to avoid confusion among players, system 200 may comprise
a means for indicating which game device 204 is currently
interacting with display unit 202. The indicating means may
comprise a video display or lighted sign on display unit 202 that
displays indicia, such as a number, that indicates the currently
interacting game device 204. A display, such as a video display or
lighted sign, may also be placed on game device 204 for conveying
similar information to the player. For example, when the player has
qualified to spin the wheels of display unit 202 but the display
unit is working on an event for another player, the display may
communicate this to the player. When it is the player's turn, the
display so informs the player.
System 200 may be adapted for use with progressive jackpots.
Display unit 202 may include a progressive jackpot meter that
displays the current value of the jackpot in a way that is well
known in the art. Players may win the progressive jackpot as a
result of obtaining a predefined outcome on display unit 202, game
device 204, or a combination of both.
It should be noted that although a clover-shaped game is described
for the preferred embodiment, any shape may be utilized with the
multi-wheel concept. In addition, the present game is not limited
to three groups of wheels with each group having three wheels. Any
number of groups, one or greater, may be utilized with each group
having any number of wheels, one or greater.
Conclusion
Although the description above contains many specifications, these
should not be construed as limiting the scope of the invention but
as merely providing illustrations of some of presently preferred
embodiments of this invention. For example, the description of the
drive mechanism should not be construed as limiting the scope of
the present invention to the structures and devices described
therein. Many other drive mechanisms may be used that would still
fall within the scope of the present invention. Thus, the scope of
the invention should be determined by the appended claims and their
legal equivalents rather than by the examples given.
