Abstract

195,824. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. Feb. 13, 1922. Electromagnets.-A relay has an armature A on which is pivoted a polarized armature A<1> which normally rests on the pole-pieces P, P<1> of the electromagnet EM and which, upon excitation of the latter, is acted on to make one of two contacts CS, the armature A being attracted to permit the turning movement. A nonmagnetic frame MB supports the electromagnet EM and the permanent magnet PM, the effective strength of which is adjustable by means of a soft-iron bolt IB. The terminals T are secured to L-shaped parts LS attached to the pole-pieces, and carry the adjustable contact screws CS, which are engaged by springs on the armature A<1> in operative position.
