Abstract
772,040. Two-part couplings. GENERAL RAILWAY SIGNAL CO. May 13, 1955 [May 13, 1954], No. 13921/55. Class 38 (1). [Also in Group XXXVII] The contacts 42, 43 of a switch (see Group XXXVII) are moulded in two-part blocks 40, 41, with a further contact 44 mounted between the two parts of each block. The projecting ends of the contacts are engaged by split socket contacts 81 having enlargements 86 trapped between insulating blocks 82, 83 which are secured together by rivets 93. The latter also clamp contacts 89 for indicating lamps 36. Conductors 92 are soldered to the projecting ends of the contacts 81 and rivets 93. Screws 90 engage captive nuts 91 in blocks 40, 41 to hold the couplings engaged.
