Abstract: A coin operated device and method of using such a device which requires a threshold number of coins to activate its operation. Once operation is stopped, however, there is provided a time window, during which the deposit of fewer than the threshold number of coins may restart the device.

Abstract: Apparatus for affixing a coin drop mechanism to the front panel of a vending machine in situations where internal tactile and visual access to the rear surface of the machine panel is limited. An external plate assembly includes guide rods extending from threaded studs which are used to align an internal plate assembly supporting the end drive mechanism. Internally threaded tubular locking fixtures applied over the guide rods to engage the studs for clamping the first and second plate assemblies around the panel. When proper assembly has been achieved the tip to the guide rods extends to the locking members to provide a tactical indication that proper installation has been achieved.
