Abstract

770,308. Electromagnetic relays; contactmembers for switches. TELEPHONE MANUFACTURING CO., Ltd. May 3,1955 '[May 13, 1954], No. 14087/54. Class 38(5) The fixed contact a of a polarized relay is finely adjustable relatively to the movable contact t by being mounted on the end of a screw f threaded in the bore of a member d, rotation of the screw being prevented by a strip g having a square opening receiving a squared portion of the screw. The member d has an external thread of a pitch differing slightly from the thread of the screw f so that when the member d is rotated in the fixed mounting arm b, the contact a is moved axially a distance related to the difference between the two thread pitches. The member d has a head m provided with teeth n engaged by a pinion o journalled in the arm b, the pinion spindle being engaged by a spanner p to effect rotation of the member d. The upturned end r of the arm b has a width s equal to one and a half times the pitch of the teeth n to provide a gauge for facilitating a predetermined adjustment of the contact. The member d is held in its adjusted position by unscrewing a screw v having a collar u which presses against a plate w interposed between the collar and the head m. The strip g also serves as an electrical connection for the contact d.
