Abstract
A timer for a dryer includes an axially movable shaft operated by a face cam and carrying a movable gear which provides different gear ratios in a gear train between the timer motor and a camstack. The driving arrangement reduces the drive speed of the camstack so that only a small portion of the timer dial is utilized during the time in which the face cam shifts the gear train into the low speed mode of operation. Another cam mounted for mutual rotation with a gear which is ahead of the movable gear and thereby unaffected by the gear shifting operation includes a lobe which operates a contact in series with the dryer drive motor to provide intermittent operation of the motor and thus intermittent tumbling of the clothes in the rotatable drum driven by the drive motor.
