Abstract

710,259. Thermal switches. DAVIS, N. R., WETHERILT, J. N., and SUNVIC CONTROLS, Ltd. Nov. 7, 1951 [Nov. 16, 1950], No. 28067/50. Class 38(5) A switch for controlling the energy supplied to a hot plate or other heating device comprises a bimetal strip 6 or other element responsive to the current and a bimetal strip 7 or the like responsive to ambient temperature, the strips 6, 7 bearing at 8, 9 on a triangular or T-shaped member the centre limb of which bears at 14 on an adjustable face cam 4 and at 16a on a snap-action switch of the trifurcated blade kind such as disclosed in Specifications 419,917 and 585,972. With changes of ambient temperature the strips 6, 7 move in opposite directions so that the position of the centre limb remains substantially unaltered. The head of the T consists of two rods 10, 11 engaging in the sockets 8, 9. The cam 4 is rotated by the rod 3 and has an off position (Fig. 1) in which notches in its periphery co-operate with abutments 43, 44 on contact blades 38, 39 to open the circuit at two points. Specification 517,538 also is referred to. Reference has been directed by the Comptroller to Specification 574,372.
