Abstract

195,424. Western Electric Co., Ltd., (Western Electric Co., Inc.). Nov. 24, 1921. Relays.-A quick-acting relay useful in automatic exchange systems has a U-shaped core 3 the legs of which have rectangular pole-faces in a plane parallel to one containing the axis of the energizing coil 1. The armature 5 co-operates with both pole-pieces and is adjustably carried by a support member 6 held between the bent polepiece 4 and a non-magnetic bridge piece 7. The armature carries a flat spring 12, the tension of which is adjustable by a screw 17 passing through a hole 13 in the armature. Adjusting screws 19 for the contact member 16 are held by rigid current-carrying members 20. In an alternative form, Fig. 2, the armature is carried by a flat spring 21 preferably of thin sheet phosphor-bronze. The spring 21 is held adjustably on the pole-piece 4 similarly to the member 6, Fig. 1.
