  • Patent number: 5411125
    Abstract: A coin chute assembly having an anti-pry mechanism. A gate, pivotally mounted on a baffle, pivots upwardly to allow passage of the coins on the inward stroke of the coin slide. On retraction of the coin slide, the gate abuts the peripheral edges of the coins to form a stop, thereby preventing retraction of the slide. A plurality of gate elements may be employed, each having a different length.
    Type: Grant

  • Patent number: 5311975
    Abstract: A coin slide extension for a coin chute assembly. A pivotal lever is connected to a mounting bracket secured to the end of an extension plate. The lever pivots over a starting mechanism upon inward movement of the coin slide, and operatively engages the starting mechanism upon outward movement. The lever abuts a stop during outward movement to prevent the lever from pivoting over the starting mechanism. In an alternative embodiment, an extension plate has two spaced apart contact legs between which a reciprocating lever of a ratchet mechanism is disposed. One leg moves the reciprocating lever to a ready position and the other moves it to an activation position.
