Abstract

846,484. Retractive switches; switches held set and freed mechanically. HOLZER, W. May 29, 1957 [June 5, 1956], No. 17000/57. Class 38 (5). A time switch controlling the motor of an electric washing-machine is controlled by a knob 1 which winds up a spring, which switches the motor off after a predetermined time. As the spring is being wound up, a cam 9 on the switch shaft 5 disengages a pawl 11 from a ratchet wheel 8, so that if a heating switch, controlled by a knob 2 on a shaft 6 carrying the wheel 8, is on, a spring 7a returns the switch to the off position. Subsequently, the heating switch may be moved to the on position and is then moved off by spring 7a when pawl 11 is again disengaged from wheel 8 when spring 7 runs down. The pawl 11 may be released electromagnetically by the time switch.
