Abstract

288,001. Sterling Telephone & Electric Co., Ltd., Blades, N., and Beard, J. R. Feb, 15, 1927. Couplings.-The ends of the windings of telephone exchange components such as relays, retardation and resistance coils are attached to tags mounted in a removable insulating block secured in the mounting plate of the relay. As shown in Fig. 4 the relay winding tags 19 are mounted in a removable insulating block 16. The block is secured in position in an aperture of the mounting-piece 5 by a screw 18 as shown in Fig. 3 and has lateral projections 17 engaging in recesses in the mounting-piece and an upward projection separating sets of contact springs also accommodated in the mounting piece 5.
