Abstract

967, 394. Temperature-responsive actuating-elements. MECHANICAL PRODUCTS Inc. Jan. 23, 1962 [Jan. 23, 1961], No. 2519/62. Heading G1D. [Also in Division H2] A high temperature switch comprises a thermally responsive probe section 10 of the rod and tube type and a snap-acting switch section 12 operated by movement of a rod 124 with change of temperature, the switch being mounted in the wall 13 of, for example, an exhaust gas purifying muffler such that the. switch section 12 is relatively unaffected by temperature changes. The substantially non-expansible rod 124 of quartz is biased into continuous engagement with the expansible metal tube 144 by a lock-up spring 20 acting through a snap-acting disc 30, on expansion of the tube 144 results in corresponding movement of the rod 124 as it follows the expansion movement of the free end 146 of the tube, and the disc 30 moves such that contacts 50, 54 snap open. A screw 82 sets the fixed contact 54 to adjust contact opening, while a screw 92 sets the disc 30 to adjust contact closing. Rod 124 is supported radially of the tube 144 by a plurality of radially compressible spring clips 160.
