Abstract
365,000. Automatic circuit-breakers. PATE, G. and LAIRD, J. R., of Carron Co., Carron, Stirlingshire. May 29, 1931, No. 15723. [Class 38 (v).] A thermally-released circuit-breaker which opens the circuit of an electric kettle &c. when the latter is overheated comprises a bimetallic strip 5 which engages an adjustable screw 12 on a lever 4, thereby rotating the lever about its pivot 9 against the action of a spring 13 till the nose 10 of the lever moves clear of a notch 11 in a push-bar 2 whereupon the bar 2 moves to the left under the action of a spring 3 and carries the operating lever 6 of a tumblertype switch into the "off " position. The circuit is reclosed by pressing in the bar 2 but this cannot be done until the kettle has cooled sufficiently for a second bimetallic strip 8, which has moved across the end of the bar 2 during the opening movement of the bar, to move back out of the path of the bar.
