Abstract
213,621. Demole, E., and M³ller, M. March 31, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches partly electromagnetic and thermal; contacts.-In order to prevent sparking between the contacts of a. thermostat controlling the temperature of an electrically-heated oven or similar apparatus by ensuring their rapid approach or separation when the heating-circuit is being established or broken, the contacts 3, 6 are arranged to be separated under the action of the thermostat 8 against the force of attraction between an electromagnet 5 and its armature 1, which is magnetized either permanently or by means of an electromagnetic field, the magnetic force decreasing rapidly when the contacts are only slightly separated owing to the interposition of an air gap in the magnetic circuit. In the construction shown, a bimetallic strip thermostat is employed operating in conjunction with a rod 7 and an adjustable abutting screw 2 on the armature 1, but a capsule or other form of thermostat may be employed. The contact 6 is mounted directly on the magnet 5, while the armature 1 is hinged to the magnet at the point 4.
