Abstract
151,446. Automatic Telephone Manufacturing Co., and Hudd, A. E. Aug. 22, 1919. Electro-magnetic switches designed as " track circuit " relays for railway signalling systems are constructed with an horizontal electro-magnet 1 and an horizontally pivoted armature 8 attracted by iron cheeks 2 at the ends of the electro-magnet and retracted by gravity. The armature carries a number of spring contacts 9 connected by flexible wires to terminals 11, and there are corresponding stationary contacts attached to terminals 13. The armature pivots about screws 6 carried on brackets 5. The electro-magnet, armature brackets, and terminals are attached to a suitably shaped cover-plate 3 which fits with rubber packing upon the edges of a rectangular glasssided box 20, and is held tightly in place by screwing into corner pillars 19.
