Abstract

467,203. Electrically-tripped switches. CRABTREE, G. E., ELLIOTT, W. T., BADHAM, E., and THORNTON, R. W., [Representatives of CRABTREE, J. A.]. Nov. 29, 1935, No. 33085. [Class 38 (v)] In automatic circuit-breakers of the kind described in Specifications 439,242 and 439,363, in which bimetallic release devices are employed with an additional bimetallic element to compensate for changes in ambient temperature, the compensating strip is made of greater thickness, or is less sensitive to changes of temperature, than the release strips. Reference has been directed by the Comptroller to Specification 383,299.
