Abstract
241,812. Brompton & Kensington Accessories Co., Ltd., and Logan, A. April 29, 1925. Thermal cut-outs. - In an electrically heated vessel C the operation of the heating circuit is controlled by a contact G actuated directly by a sliding rod E under tha action of a stressed spring F normally held by a fusible plug D disposed so as to melt and release the spring when the level of the water in the vessel is unduly low. The spring F, rod E and plug D are enclosed in a tube A in contact with the bottom of the vessel or the top of an immersion heater B. The spring is anchored in tension or compression by the rod E one end of which rests on a bearing A<1>, the other end being fitted with a collar E<2> and being fixed on the fusible plug D. The contact G may be normally in the open position and when the plug melts may close a relay circuit controlling the heater circuits.
