Abstract

201,733. British Thomson - Houston Co., Ltd., (International Electric Co., Inc.). July 8, 1922. Thermal switches.-A thermostat for controlling the heating circuit of an electric oven or the like, comprises a bimetallic strip 35 fixed at one end to a shaft 38 and provided at the other end with a slotted member 39 engaging a pin 40 adjustably secured to the support 36. A switch operating arm 41, adjustably mounted on the shaft 38 is provided with a sector 42 adapted to engage a pivoted lever 43 for operating a switch mounted on an adjustable arm 44. A quadrant 46 serves as a support for the shaft 38 and arms 41, 44, the latter being provided with pointers 48, 49 which co-operate with a scale 47 on the quadrant. When the sector 42 engages the roller 54 on the arm 43 the screw 55 forces the spring 58 away from the contact screw 59, and opens the circuit of the operating coil of the switch, the circuit being re-established as soon as the sector 42 and roller 43 become disengaged.
