Abstract

215,679. Tyer & Co., Ltd., and Leake, F. W. Dec. 10, 1923. Electromagnets.-A tubular casing A is closed at one end a and diametrically opposite poles are formed at the open end to co-operate with an armature G carried by a core B which is rotatably mounted on a pivot E at the closed end' of the casing and in a non-magnetic bar F at the open end. The armature is shaped as shown to maintain an approximately constant attractive force throughout its range of movement, which may be limited by stops l, m. The core may carry an index H, or a railway signal, or a locking-dise &c.
