Abstract

873,956. Thermal switches. DRAYTON REGULATOR & INSTRUMENT CO. Ltd., and FORSTER, R. R. Nov. 7, 1957 [Nov. 8, 1956], No. 34209/56. Class 38 (5). [Also in Group XIII] A thermostat controlling a spaceheater has an accelerating heater 3 which is carried by a clip 7 formed by the crosspiece of a U-shaped bimetal element 4. When cold, the heater 3 is in contact with the thermal element 5 of the thermostat, but when heated, the element 4 deflects and moves the heater away from the element 5 and reduces its effect thereon.
