  • Patent number: 5030165
    Abstract: Coin assorting device having a disc (12) mounted for rotation on a bottom plate (10) to pass below a coin supply tube (19). The rotatable disc includes two pairs of recesses (16) for receiving a coin in each recess, the bottom plate having a discharge opening (20) for coins the diameter of which is less than a predetermined maximum diameter of the coins supplied. The discharge opening (20) extends beneath the mouth of the coin supply tube (19) and is shaped with an upper chamfered edge (24). Opposite sides of the wings (14) of the rotatable disc (12) are shaped in the form of blunt edges having a thickness which substantially corresponds to the thickness of the thinnest occurring coin. Circuitry is associated with the rotatable disc (12) for momentarily reversing the rotational movement of the disc when a coin jamming is sensed.
