Abstract

295,310. Fairweather, H. G. C., (Wilcolator Co.). Feb. 7, 1927. Divided on 292,192, [Class 38 (v), Electric switches &c.]. Controlling consuming devices. - An electric heater 69 is supplied from mains 67, 68. through a main switch 70 closed by a solenoid 71. When the heater is not energized, the thermal switch lies against the contact. 61 whereby the circuit is completed through 72, resistance 73, contacts 61, 37, line 74, solenoid 71 and line 75. This energizes the solenoid 71 and closes the main switch 70. When the element 37 leaves the contact 71 due to increase of temperature, the solenoid still remains energized through circuit 72, 77, resistance 79, solenoid 71, and line 75. When the element 37 reaches the contact 53, the solenoid 71 is short circuited through line 74 and contacts 37, 53 and the main switch 70 is opened.
