v My invention relates to switches and vparticularly to thermal-responsive quick-acting switches.
One object of m invention is to provide a device of the aiiove indicated character that shall have means fonquickly making and breaking a'crcuit inresponse to predetermined conditions of temperature.
Another object of my invention is to provide a device of the above indicatedcharacter that shall have its contact members electromagnetically actuated in accordance `with predetermined conditions.
A further object of myinvention is to provide a device of the abovelindicated character that shall be simple to construct yet effective anl'eliicien't in` its operation.;
In the carrying-olii: of fr iiyfiinventionf I provide stationary contact able bridging contact member normally biased into enga ementtherewith and having a magnetizabe portion at one side there-` of. An electromagnet is adapted to attract the magnctizable portion of thebrid 'ng member for the purpose of quickly disengaging the same from the stationary contact members, and a. bimetallic thermalresponsive device is provided for'controlling the energization of the electromagnet. Thus, when the temperature to which the device is subjected reaches a' predetermined value, the contact members may he quickly und positively actuated.

The bridging contact member 8 is adapted to be' held in en gement with ,the stationarygcontact mem mal conditions. The bridging contact member Sis provided with a magnetizable portion 10 that isa'dapted to be' loosely'surrounded by a bimetallicmember 11 which is secured, at its lower end, to the insulating member 3. An electromagnet 12 is secured to a supporting member 4 that is mounted on the insulatih lian v2, and one terminal 13 of the winding o the electroma et is operatively connected to an" adjustab e contact member 14 which is also mounted on the. supporting member 4. he position of `the contact member 14 is adapted to be adjusted by s. screw member 15.` A contact member 16 is mounted at the upper end of the bimetallic member 11 and is adapted to engage the contact member 14, 'under predetermined conditions. The contact members 14 and 16 constitute separable terminals of a circuit comprising'the AWinding; of the electromagnet' and a source 17 of electromotive force.
.lVhen the member 1 is inserted in a hot water heater, a furnace, an oven or other device, the temperature of which is to be controlled, the bimetallie member 11 is adapted to bend under the unequal expansion' of its two unlike portions, and its contact member 16 will engage the stationary Contact member 14 when the temperature reaches a. predetermined vaille, as determined by the position of the member 14. This will coruplete a circuit' through the winding,Y of the elcctromag'net l2 for the purpose of euergizing the saine. lVheu the electrnmagiiet 12 is energized, the iuagnetizablc portion 10 of the movable bridging member H will be attracted und the member 8 will be quickly disengaged from the. stationary contact members 5 and (i. The, stationary contact members 5 and f iuuv be. adapted to control any suitable device in ueeorilunco with the application to which the theruull-responsivc switch is appl-ind.
