Abstract

23,917. Railing, M. J., Strachan, J., and Hoadley, E. E. Oct. 19. Electro-magnetic interrupters of the automatic current - limiter type are constructed with a comparatively light iron armature g pivoted between a stationary pole-piece b and an adjustable pole-piece d energized by a winding c mounted on a limb a, which together with the pole-piece b forms an L-shaped core, When a sufficient current flows, the armature swings about its pivot h away from a stop k on which it normally rests, and strikes a pivoted contact lever o, thus breaking the circuit at the contacts q, s. Carbon, metal, or mercury-cup contacts are used according to the strength of current. The contacts may be joined by a resistance so that the circuit is never completely broken. The parts return after the break, and the make and break is continually repeated as long as the limit is exceeded. The preliminary setting of the adjustable pole-piece d is shown on a scale of amperes m. A window in the casing of the instrument and an outside milled handle may be provided. Specification 10,654/10 is referred to.
