ABSTRACT:
A drive mechanism for a timer includes a drive pawl having a pin which is trapped between two camming surfaces of a continuously driven drive cam. The drive pawl is slidably mounted in the timer frame so that it is linearly reciprocated when the drive cam is rotated. A spring biases the drive pawl against the ratchet track.
