Abstract
Abstract A coin counting machine is described having an anti-jamming device for removing jammed coins from a passageway. A jam detection circuit is provided for indicating the jamming of a passageway. A stop control circuit is provided whereby the coin counting machine operation is halted at which time the jam is removed. Jam removal is accomplished by reversing direction of operation of the counting machine. The apparatus described thereby prevents damage to the machine which would normally result from coin jamming.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
Coin counting machine comprising a rotatable disc disposed in a peripheral wall having an outlet, a motor for driving said disc, a coin passageway provided contiguous with said outlet in the peripheral wall and including a coin feeding member for driving coins along the passageway, means for driving the coin feeding member, means for counting the number of coins which have passed through the passageway, means for sensing coin jamming, and means for operating the motor and the means for driving in one direction under normal operation and reversing the direction of operation of at least the drive means when coin jamming has been sensed.
Claim 2
Dependent Claim
105 words
Coin counting machine comprising a rotatable disc disposed in a peripheral wall having an outlet, a motor for driving said disc, a coin passageway provided contiguous with said outlet in the peripheral wall and including a coin feeding member for driving coins along the passageway, means for driving the coin feeding member, means for counting the number of coins which have passed through the passageway, means for sensing coin jamming, and means for operating the motor and the means for driving in one direction under normal operation and reversing the direction of operation of at least the drive means when coin jamming has been sensed.
Claim 3
Dependent Claim
32 words
Coin counting machine in accordance with claim 1 in which both of the motor and the means for driving are operated in the reverse direction when the coin jamming has been sensed.
Claim 4
Dependent Claim
53 words
Coin counting machine in accordance with claim 1 in which said means for sensing coin jamming includes means for receiving a counting signal from said means for counting for producing a jam signal when a succeeding counting signal has not been received within a predetermined time after a preceding signal has been received.
Claim 5
Dependent Claim
33 words
Coin counting machine in accordance with claim 1 in which means is provided for automatically returning the machine into the normal operation after the reverse operation has been continued for a predetermined time.
Claim 6
Dependent Claim
27 words
Coin counting machine in accordance with claim 4 in which means is provided for stopping the machine when a predetermined number of reverse operations have successively occurred.
