Abstract

328,923. Saunders, P. Feb. 5, 1929. Dials.-A time switch adapted to close a circuit after a predetermined time comprises a contact or contact actuating member J fixed on a member A fixed to the hour wheel B of a clock movement, the member A being rotated through any desired angle by means of a handle L which detachably engages the cannon pinion P and then returning under the drive of the clockwork till the member J, for example, bridges contact Q. The member A may be a cup enclosing the clock movement and carries an indicating member such as a dial which may be observed through a window K in the surrounding casing. The usual winder S for the clockwork is provided.
