Abstract
Timer suitable for the automatic control of appliances. The timer includes a contact structure which is activated by a rocking lever and two adjustment shafts which move the rocking lever when the shafts are manipulated to set the starting and stopping times of the timer. The rocking lever is maintained in the necessary position for manual operation of the applicance by the cooperation of a locking lever, an ear extending from the rocking lever, and an opening in the plate which supports the rocking lever. The locking lever covers the opening and prevents the penetration of the ear therein when the timer is set for manual operation. With this arrangement, the shafts are free to rotate according to the correct time.
