Description
This invention relates to an amusement device and has particular
reference to such device which is designed for playing by matching
or pairing suitable combinations of symbols provided thereon.
The present invention has for an object to provide an amusement or
toy device of the class described which is very simple in
construction and easy in operation, and which may be further built
compact to adapt itself for use by children. This object together
with other advantages of the invention will be apparent from the
following description taken in connection with the accompanying
drawings in which:
FIG. 1 is a front elevational view of an amusement device in
accordance with the invention;
FIG. 2 is a rear elevational view of the same;
FIG. 3 is a side view partly sectional, of interior components of
the device, illustrating in particular a drum actuating mechanism
as in its operative position;
FIG. 4 is a view similar to FIG. 3, but with the drum actuating
mechanism in its inoperative position; and
FIG. 5 is a perspective view of operating members of the device
including pushbuttons and a handle lever.
Briefly stated, the device according to the invention comprises a
generally rectangular casing, a plurality of drums each rotatably
mounted on a common shaft secured to the sidewalls of said casing
and having on its periphery at circumferentially spaced positions
various combinations of symbols such as for example pictures,
letters, numerals and the like; a drum actuating mechanism
including a drive shaft connected via reduction gears to a motor
and a transmission roller normally engaged with said drive shaft to
effect rotation of each drum; a drum braking mechanism including a
cam wheel having a plurality of circumferential grooves and secured
to one side of the drum and a stop roller disposed for engagement
with said cam wheel to discontinue rotation of the drum; a rotative
forked lever member carrying said transmission roller rotatably on
one arm thereof for engagement between said drive shaft and drum
surface and said braking roller rotatably on the other arm for
engagement with said cam wheel; a plurality of pushbuttons
projecting externally of the front wall of said casing; a
connecting rod connecting between each of said pushbuttons with
said forked member; a shaft journaled for rotation between the
sidewalls of said casing subjacent said pushbuttons; a handle
secured to one end of said shaft and extending externally of one
sidewall of the casing; and release means including a plate member
pivotally mounted on said shaft and a press or member secured to
said shaft and abutting against said plate member, said means
having a first position determined upon depression of any of said
pushbuttons wherein the drum associated with the thus depressed
pushbutton is brought to a stop and a second position determined
upon a return movement of said handle to release all of said
pushbuttons wherein rotation of all of said drums is effected.
Referring now to the drawings and to FIGS. 1 and 2 in particular,
there is shown an amusement device 10 embodying the invention and
comprising a casing 11 which may be generally rectangular for
accommodating therein a variety of components and parts of the
device and which is formed by a front panel 12, a rear cover 13 and
sidewalls (not shown). The front panel 12 is provided with a
display window 14 to expose to a view a portion of the peripheral
surface of each of a plurality of drums 15 mounted for rotation on
a common shaft 16 between the sidewalls of the casing 11. Each drum
15 shown by imaginary line in FIG. 1 is provided on its periphery
at circumferentially spaced positions with suitable combinations of
symbols 17 which are successively viewable through the window 14 as
the drums rotate. The front panel 11 is further provided with as
many pushbuttons 18 as are the drums 15 for stopping the rotation
of the latter in a manner hereinafter described. Designated at 19
is a rotatable handle connected with a release means later
described for releasing the pushbuttons to resume rotation of the
drums. Designated at 20 is a switch knob for turning on and off a
motor schematically shown at M in FIGS. 3 and 4. The rear cover 13
is provided at its lower portion with a battery compartment cover
21 hinged as at 22 to the cover 13.
Turning to FIGS. 3 and 4, the drum 15 is shown as associated with
its actuating mechanism including a forked lever member 23 having
bifurcated arms 23a and 23b. The arm 23a has rotatably carried at
an end thereof a transmission roller 24 preferably made of rubber
engageable between the drum surface and a drive shaft 25. A tip end
of the other arm 23b of the forked member 23 has rotatably carried
thereon a braking roller 26 engageable with a cam wheel 27 secured
to one side of the drum 15. The cam wheel 27 is provided around its
peripheral surface with grooves 27a for engagement with the braking
roller 26. The grooves 27a correspond in number to the symbols 17
on each drum 15 and are positioned to register with the latter, so
that as the braking roller 26 engages any particular groove, the
drum stops instantaneously with a predetermined one of the symbols
17 stationarily viewable through the window 14. The forked member
23 has its stem portion 28 connected to one end of a connecting rod
29, the other end of which rod is connected to the pushbutton 18,
in such manner that the pushbutton may be depressed to pivot the
forked member 23 about a pin 30 into a position wherein the braking
roller 26 engages the cam wheel 27 to stop the drum as seen in FIG.
4. In this position of the device, the transmission roller 24 is
released from engagement between the drive shaft 25 and the drum
surface so that transmission of the rotational power from the motor
M to the drum is discontinued as shown in FIG. 3. The drive shaft
25 is connected to the motor M via suitable reduction gears
indicated by imaginary line and is normally held in rotation with
the switch 20 in on-position.
Referring to FIG. 5, there is shown a release means 31 including a
plate member 32 having a lug 33 for pivotal and extending axially
thereof and a pressor member 35 secured to the shaft 34 and
normally urged by a spring 36 toward the forked lever member 23.
The handle 19 is secured by means of a flange 37 to an external end
of the shaft 34. The plate member 32 has its upper longitudinal
edge portion disposed for abutting relation to the pushbuttons 18.
The pressor member 35 of the release means 31 has a projection 35a
extending behind the plate member 32 in abutting relation thereto,
whereby as the handle 19 is rotated by hand counterclockwise, viz,
in the direction of an arrow shown, the pressor member 35 rotates
therewith and presses the plate member 32 against the pushbuttons
18 against tension in the spring 36, thus returning the pushbuttons
to a released position as illustrated in FIG. 3. In this position
of the pushbuttons 18, all drums 15 are held in actuated position
wherein the transmission rollers 24 are engaged with the drive
shaft 25 and drum surface to thereby effect rotation of the drums
and the braking roller 26 is disengaged from the cam wheel 27.
While the drums 15 are thus in rotation, the pushbuttons 18 may be
successively depressed with an aim to match or pair the symbols 17
on the drums. Depression of each pushbutton causes the forked lever
23 to move counterclockwise so as to bring the braking roller 26
into engagement with a predetermined one of the grooves 27a in the
cam wheel 27 and simultaneously to displace the transmission roller
24 apart from the drive shaft 25 and from the periphery of the drum
associated with the depressed pushbutton as shown in FIG. 4,
whereby this drum is brought to a stop with a certain symbol 17
thereon exposed to a view through the window 14. Depression of the
remaining pushbuttons 18 acts upon the respective forked levers 23
in the manner already described to discontinue the rotation of the
drums associated with the thus depressed pushbuttons. Designated at
38 is a spring adapted to stabilize the position of the forked
lever 23.
Having thus described the invention, it is to be understood that
the invention is not to be limited to the specific form and
construction described herein above and shown in the accompanying
drawings, but various changes and modifications may be made therein
without departing from the scope of the appended claims.
