Countdown and start mechanism for an electrostatic copier

摘要

A countdown and start mechanism for a cyclically operable machine wherein an escapement mechanism is adapted for the countdown control. An escape wheel is provided to concentrically carry a cycle counter knob for indicating the number of cycles to be performed. An anchor is actuated once during each cycle of the machine to incrementally step the escape wheel down toward a null position whereupon the machine is stopped. A start mechanism is provided to actuate the machine after the counter knob is set for a given number of operations or for a single cycle when no setting is made.
