US 4,430,903 A · Gaming apparatus having manually controllable operating speed

Abstract

An improved amusement or game device of the type which has one or more indicia-bearing rotatable reels which are rotated upon initiation of play by a player is disclosed. The game device has an improved main drive mechanism which permits the player to vary the initial rotational speed of the reels in direct proportion to the speed in which an associated operating handle is pulled. A supplemental drive mechanism is included for increasing the speed of the reels if the player fails to pull the operating handle with sufficient force to rotate the reels at a predetermined minimum speed. The device also includes an improved indexing means for stopping the reels in accordance with the operation of the game device. The game device also includes means for absorbing excessive energy that may be provided by a player pulling the operating handle with extraordinary speed or force. A mechanism is also included for providing slight resistance to movement of the reels subsequently of enablement of the game device and immediately before pulling of the operating handle, during which time the reels are otherwise free to rotate since neither the main drive mechanism, the supplemental drive mechanism nor the indexing mechanism is engaged at this time.

Dependent claims

A drive mechanism for increasing the rotational speed of a shaft carrying a toothed ratchet means in response to actuation thereof and comprising:

plate means that is movable relative to said shaft from a rest position to an extended position;
pawl means carried by said plate means and being adapted to be moved relative to said plate means and engage the toothed ratchet means;
means for biasing and said pawl means toward engagement with said ratchet means;
latch means carried by said plate means for retaining said pawl means out of engagement with said ratchet means and for releasing said pawl means when operated;
means for operating said latch means to release said latch means in response to activation thereof;
drive means operably connected to said plate means for moving the same from said rest position to said extended position subsequently of the activation of said operating means;
means for disengaging said pawl means and for resetting said latch means in response to movement of said plate means to said extended position;
means for sequentially activating said latch means operating means followed by said drive means in response to initiation thereof;
and,
means for detecting the rotational speed of said shaft and for initiating operation of said activating means in response to the detection of the rotational speed being slower than a predetermined speed.

A drive mechanism for increasing the speed of a rotating shaft that has a toothed ratchet means fixedly attached thereto, said mechanism operating in response to an indication that the shaft is rotating below a predetermined minimum speed, the shaft being journaled in a frame structure of a game device, said mechanism comprising:

plate means that is carried by and is rotatable about said shaft and being rotatable between a rest position and an extended position;
a pawl means pivotably attached to said plate means and having at least one surface adapted to engage the teeth of said ratchet means when said pawl means is pivoted toward engagement;
means for biasing said pawl means toward engagement with said ratchet means;
latch means pivotably attached to said plate means for retaining said pawl means out of engagement with said ratchet means and for releasing said pawl means when operated, said latch means including means for biasing the same toward engagement with said pawl means;
means for operationg said latch means to release said latch means in response to a first operating signal being applied thereto;
drive means operably connected to said plate means for moving the same from said rest position to said extended position in response to receiving a second operating signal;
control means for detecting that said shaft is rotating at a speed below said predetermined speed and for generating said first operating signal followed by said second operating signal;
and
means for disengaging said pawl means and for resetting said latch means in response to movement of said plate means to said extended position.

6 more elements

In an apparatus of the type wherein a rotatable shaft is journaled at opposite ends in a frame structure and has a toothed ratchet wheel atached to one end portion of the shaft, a mechanism for momentarily driving the shaft to increase its rotational speed, said mechanism comprising:

a plate means rotatable around said shaft and carrying a pivotable pawl means for engagement with said ratchet wheel when released, the pawl means being biased toward said engagement;
a latch means for retaining said pawl means out of said engagement and for releasing the same when operated;
means for operating said latch means when actuated;
drive means for moving said plate means through a predetermined arc to drively rotate said ratchet wheel when said pawl means is engaged therewith;
cam means for contacting said pawl means as said pawl means approaches the end of said predetermined arc to move it out of engagement from said ratchet wheel and to reset said latch means so that it retains said pawl means;
means for actuating said operating means and for thereafter actuating said drive means in response to a control signal being received;
and,
means for detecting the speed of rotation of said shaft and for generating said control signal in response to said detected speed being below a predetermined speed.
