Abstract
198,367. Soc. Anon. Calor. May 29, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches partly electromagnetic; thermal switches; springs, arrangement of.-A switch, operated by changes in temperature, comprises a permanent or electromagnet acting in opposite directions on a soft iron lever e, articulated at one end f and carrying at its free end a contact k which engages a fixed contact l. The lever e is acted on by a rod d actuated by a membrane b through springs h, h<1> and adjustable nuts i. Excess temperature acts on the membrane b to raise the rod d and stress the lower spring h<1>, and at a given temperature the lever e is forced away from the pole j<11> into the field of the pole j<1> which attracts it, thereby opening the switch. When the membrane retracts, assisted by its spring r, the spring h acts to re-close the switch in a similar way. With suitable modification, the device may be adapted for use as a fire alarm.
