US3759525A — Electrical actuated chance device having chain-dr…

Claim 1

Independent Claim 345 words

In the combination with: a game apparatus of the type having a plurality of reels with markings on each reel about its periphery, a stop sprocket at one side of each reel and a ratchet bearing at the axis of each reel; a rotatable shaft whereon the reels are mounted in a side by side relationship, with the shaft being fitted in the ratchet bearings of the reels to permit each reel to rotate upon the shaft in one direction only; a detent adjacent to each reel biased to engage the stop sprocket to stop rotation of the reel; a releasable holding means adjacent to each detent to engage and hold the detent when it is moved against its bias and away from engagement with its stop sprocket; a shifting means to shift all of the detents away from their engagement with their stop sprockets and to engagement with the holding means; and a manual release means at each holding means to release the detent from the holding means to permit the same to engage the stop sprocket and stop rotation of the reel; the improvement of a means to suddenly rotate the shaft in the direction of reel rotation to lock the ratchet bearings and thereby spin the reels when the shifting means shifts the detents, comprising: a chain sprocket upon the shaft; a chain partly wrapped about the sprocket; a solenoid having a normally extended armature connected with that end of the chain which, when pulled into the solenoid, when the solenoid is energized, rotates the chain sprocket and shaft thereon in the direction of reel rotation; a tension spring at the other end of the chain to return the chain to its initial position whenever the solenoid is deenergized and the solenoid armature is extended; a circuit means including a normally open switching means which closes to energize the solenoid to pull the armature into the solenoid; and means to close the switching means responsive to the shifting of the detents away from the sprockets and to engagement with the holding means.

Claim 2

Dependent Claim 345 words

In the combination with: a game apparatus of the type having a plurality of reels with markings on each reel about its periphery, a stop sprocket at one side of each reel and a ratchet bearing at the axis of each reel; a rotatable shaft whereon the reels are mounted in a side by side relationship, with the shaft being fitted in the ratchet bearings of the reels to permit each reel to rotate upon the shaft in one direction only; a detent adjacent to each reel biased to engage the stop sprocket to stop rotation of the reel; a releasable holding means adjacent to each detent to engage and hold the detent when it is moved against its bias and away from engagement with its stop sprocket; a shifting means to shift all of the detents away from their engagement with their stop sprockets and to engagement with the holding means; and a manual release means at each holding means to release the detent from the holding means to permit the same to engage the stop sprocket and stop rotation of the reel; the improvement of a means to suddenly rotate the shaft in the direction of reel rotation to lock the ratchet bearings and thereby spin the reels when the shifting means shifts the detents, comprising: a chain sprocket upon the shaft; a chain partly wrapped about the sprocket; a solenoid having a normally extended armature connected with that end of the chain which, when pulled into the solenoid, when the solenoid is energized, rotates the chain sprocket and shaft thereon in the direction of reel rotation; a tension spring at the other end of the chain to return the chain to its initial position whenever the solenoid is deenergized and the solenoid armature is extended; a circuit means including a normally open switching means which closes to energize the solenoid to pull the armature into the solenoid; and means to close the switching means responsive to the shifting of the detents away from the sprockets and to engagement with the holding means.

Claim 3

Dependent Claim 49 words

In the combination defined in claim 1, wherein: the aforesaid chain sprocket is mounted upon a ratchet bearing upon the shaft which is directed oppositely from the ratchet bearings in the reels, whereby the shaft will not reverse when the tension spring returns the chain to its initial position.

Claim 4

Dependent Claim 82 words

In the organization defined in claim 1, wherein the shifting means to shift the detents includes a second solenoid; and a second circuit means therefor adapted to energize this second solenoid to effect the aforesaid shift of the detents; and the means to close the switching means of the first mentioned circuit means includes a delay means does not permit the closing the of the first switching means until the said second solenoid is energized to effect a shift of its armature.

Claim 5

Dependent Claim 27 words

In the organization defined in claim 3, wherein: said means to close the aforesaid switching means includes a limit switch operable when the second solenoid is energized.
