Abstract

708,985. Electromagnetic relays. WESTING- HOUSE AIR BRAKE CO. April 2, 1952 [April 19, 1951], No. 8376/52. Class 38(5) A light weight relay that may be hermetically sealed comprises a magnetic shell 1, a core 5 surrounded by a winding 17 and supporting in a bearing 9 a spindle 33 carrying a multi-armed armature 29, Fig. 4, adapted to be attracted to a corresponding number of fixed pole pieces 27. The armature 29 supports a cup 35 the rim 41 of which has slots 42, Fig. 3, engaged by movable contact springs 51 mounted on terminal posts 43 extending through glass or ceramic beads 45 in a cover 39 which similarly supports the terminal posts 43 carrying the fixed contact sleeves 47 of silver-platinum. The posts 43 and the cover 39 may be of " Kovar " (R.T.M.) and the bias of the springs 51 is such as to bias the armature away from the poles 27. The relay may be exhausted of air and filled with a suitable gas through a hole 7 which may later serve for mounting the relay. The contacts 43 may also plug into a socket device. The two leads from the winding 17 extend through tubes passing upwards through the cover 39.
