ABSTRACT:
A coin slide actuated timer mechanism is provided for a commercial apparatus such as an automatic fabric drying machine. The timer mechanism includes an indexing mechanism by which preselected angles of timer drive shaft rotation corresponding to desired periods of machine operating time can be manually preset. A movable peg member can be placed in various angularly spaced locations on an index wheel which correspond to the desired periods of operating time and when the timer drive motor is energized the index wheel will be rotated with the timer drive shaft to move the movable peg member into engagement with a switch actuator for initiating the termination of the time period. The index wheel is rotatably biased upon the timer drive shaft for resetting to a start posture upon actuation of a coin slide actuator.
