Abstract

556,654. Electromagnetic switches. GRAHAM & CO., Ltd., A., and VAUGHAN, C. H. May 6, 1942, No. 6093. [Class 38 (v)] For setting the air-gap between the armature 12 and the poles of the electromagnet 11, the knife-edge fulcrum 14 for the armature is made adjustable. The knife-edge 14 may form part of a member which is U-shape in section for most of its length and which slides on the R.H. wing of a frame 1, being finally fixed in its adjusted position by screw 21.
