Abstract

733,403. Automatic temperature control systems. COLE, Ltd., E. K., and BIGGINS, H. W. Dec. 21, 1953 [Oct. 20, 1953], No. 28887/53. Class 38 (4). In Fig. 1 the supply to an electric oven heater M1 is controlled by contacts D of a relay B which is operated intermittently by virtue of contacts C of a bimetallic switch, the bimetallic strip A of which is associated with a heater AH connected in parallel with relay winding B. The on/off time ratio is controlled by the position, of a stop El against which strip A bears. Bending of strip A due to heating causes a strip F to pivot about P1 and open contacts C. Strip F is also bimetallic to provide ambient temperature compensation. The position of stop E 1 is automatically varied through a bell-crank lever L by a bellows Y communicating with a fluid-expansion bulb M2 in the oven so that the on/off ratio is reduced as the oven temperature rises. A modified form of lever operating stop E1 is described with reference to Fig. 3 (not shown).
