Abstract: 1,020,925. Thermal switches; cam-operated switches. GENERAL ELECTRIC CO. Nov. 13, 1962 [Nov. 28, 1961], No. 42882/62. Heading H2B. A thermostat for a radiant heating system has a capsule 17 brazed to the underside of a pivoted lever 7 of heat conductive material which provides mechanical protection and means for adjusting the operating temperature whilst allowing the capsule to be affected by both ambient air temperature and radiant heat. The lever 7 is carried on a base-plate 2 by means of a pin 34 passing through triangular apertures 37 and 38 in tabs 35 and 36 provided respectively on the plate 2 and lever 7. A spring 25 acting against the .diaphragm 17a (Fig. 3, not shown) of capsule 17 urges a projection 31 on the lever 7 against the cam surface 30 of an adjusting knob 8. The triangular apertures 37 and 38 are mutually inverted as shown so that under action of spring 25 the pin 24 accurately locates the pivot axis but permits considerable relative movement between lever 7 and baseplate 2 to. absorb mechanical shocks without detriment to the capsule 17 or calibration of the thermostat. Slots 18 in lever 7 permit air flow around capsule 17 and a decorative cover 14 has an aperture 15 for the adjusting knob 8 and a further aperture 16 opposite the part of lever 7 carrying capsule 17 to allow radiant heat to be conducted via lever 7 to the capsule. A switch housing comprising two parts 43, 44 is held to plate 2 by screws 41 and 42 which also secure an insulating spacer 45 with: side flaps 46, 47 and bottom tabs 48, 49 which separate the switch from the mounting box for the whole device (Fig. 2, not shown). Two contacts 54, 55 on a moving arm 51 co-operate with fixed contacts 56, 57 and are connected to terminals 64, 65 in the housing by flexible straps 71, 72. The arm 51 is pivoted on the tip 52 of a screw 53 (used to set the calibration of knob 8 during manufacture) and is urged by two springs 58, 59 against the action of capsule 17 via rod 22. Owing to the pointed end 60 of rod 22 and rounded tip 52 of screw 53, one of the moving contacts will usually operate before the other. Adjustable abutments 80 and 81 are provided on plate 2 for co-operation with a projection 86 to limit the range of adjustment of knob 80 if desired. Knob 8 may be turned to an "OFF" position wherein an arm 77 depresses a rod 76 to hold the switch arm 51 in the open position, and abutment 80 may be adjusted to lock the knob in this condition, during the summer for example.
