Abstract
A coin-operated liquid dispensing machine having a vending control mechanism which may be conveniently altered to accept a different coin or series of coins to reflect different vending prices that are to be charged. In the disclosed arrangement vending prices of 5.cent., 10.cent., 15.cent., 20.cent., 25.cent. and 30.cent. are selectable. The control mechanism includes a timer motor for driving three cams each having electrical circuitry associated therewith including cam contact switches. The first cam is a stepping cam, the second an override cam and the third cam controls a dispensing gear motor. The electrical circuitry also includes 5.cent. and 10.cent. switches and associated relays, a relay by-pass switch, and manually operated blocking structure associated with each coin slot (5.cent. and 10.cent. slot). Change in vending price is accomplished by setting the cam path of the second cam to one of two different settings, operating the by-pass switch to either an open or closed position, and selectively energizing one of the blocking structure for some prices. All operations for changing price are done in accordance with a predetermined scheme to permit dispensing only after the proper coin or coins have been deposited in the machine.
