  • Patent number: 4585111
    Abstract: In a manually operated coin slide mechanism, the usual coin receiving coin slide is permitted a full inward stroke regardless of the value or validity of the coin inserted therein. Actuation of an apparatus controlled by the mechanism is governed instead by a secondary slide yieldingly coupled to the coin slide, and whose displacement is dependent upon the value and validity of the coin. The mechanism is thus protected against damage resulting from the use of brute force by vandals, and is further readily adapted to accept coins of different values, since the degree of displacement of the secondary slide can be made dependent upon the coin value.
