Abstract
781,642. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd. Oct. 20, 1955 [Nov. 3, 1954], No. 31834/54. Class 38 (5). An adjustable armature mounting shown applied to the pollarized relay disclosed in Specification 781,641 comprises a resilient strip 14 clamped between the upper and lower halves of a plate armature 10, the two ends 22 of the strip being apertured and receiving bushes 23 resting on the conical ends of screws 24 threaded in side arms 2 of the relay frame 1. Arms 25 of a plate 26, to which the bushes 23 are riveted, press on the strip ends 22 and are engaged by bearers 29 to hold the bushes against the screws 24. The plate 26 is further retained by the head of a screw 27 passing through an aperture 28 therein and threaded into the relay frame. On energization of the coil 9, the armature rocks about the strip 14 and a ball 16 on a cranked armature extension 15 operates contact springs 17. By adjusting the screws 24 unequally and by slight adjustment of the screw 27, the armature is tilted about its longitudinal axis, by adjusting the screw 27 the armature is tilted about its rocking axis, and by adjusting screws 24 equally and with slight adjustment of the screw 27 the armature may be moved bodily up or down.
