Abstract

782,405. Electromagnetic relays ; contactmembers for switches. WESTINGHOUSE AIR BRAKE CO. Dec. 14, 1955 [Dec. 14, 1954], No. 35861/55. Class 38 (5). In a relay including the features disclosed in Specifications 773,852 and 775,421 in which an armature 6 is attracted towards L-shaped polepieces 3, 4 to operate contact springs 44 through a member 15, the moving contact blade supports 54 and the fixed contact blades 43 are mounted in pairs in rectangular apertures 42 in an insulating block 16. Each aperture receives a pair of insulating channel-section blocks 82 having projections 81 engaging an opening 80 in a blade 43 or 54 and the faces 86 of the blocks are inclined to receive a wedge 83, so that when the blocks and blades are inserted into an aperture 42 until the blocks engage a bridge 87 extending thereacross and a bolt 85 is then threaded into the wedge, the blades are clamped between the blocks 82 and opposite walls of the aperture 42. Indexing pins 73 which may be positioned at selected locations co-operate with corresponding holes in the plug-in base (Figs. 1a, 2, not shown) and ensure that only the correct relay may be plugged into the base.
