Abstract

536,355. Switchboards; two-part couplings. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. March 11, 1940, No. 4526. Convention date, Aug. 24, 1939. [Class 38 (v)] [Also in Group XXXVI] Relates to the mounting of relays such as described in Specifications 498,855 and 500,964 and several hundred of which may be used in a traffic controlling system such as described in Specification 473,310, [Group XXXVIII]. To ensure the. right relay always being plugged into the right connector, each type of relay such as A or B has projections 21 arranged at a special position and adapted to engage recesses 20 on the supports C1, C2. In addition specially-placed recesses 30 in the back plate of the relay engage specially-placed pins 29 in a base plate 26. The recesses 30 may be formed by removing selected numbered portions from a strip of back plate formed as in Fig. 7 and the pins 29 may be inserted into selected holes in the plate 26. The relays A, B are inserted from the front, Fig. 1, their outwardly projecting contacts 1 entering slots in the side supports C1, C2, C3, C4 and there engaging terminal contacts. A cover plate 31 which pivots about a V-spring 35, Fig. 5, which is inserted into slots 36 in adjacent supports C1, C4 is then swung into position, its upper end hooking over the top of the supports C1, C4.
