Abstract

298,897. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Oct. 15, 1927, [Convention date]. Thermostats.-The heat-sensitive member of a thermal switch is embedded in a mass m which when cold or of normal room temperature is solid, but when heated is yielding, that is to say, soft or liquid. A suitable substance is a mixture of bitumen and mineral oils. The Figure shows a bimetallic coil b the outer end of which is connected to the vessel g and the inner end of which is connected to an axle a carrying a contact arm k. Current flowing through the coil b heats it and the mass m, which when sufficiently soft allows the coil to turn the axle a and bring the arm k into engagement with a stationary contact.
