Abstract

786,959. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd. Sept. 6, 1955 [Sept. 7, 1954], No. 25911/54. Class 38 (5). A relay arrangement comprises an L-shaped yoke 21 having a number of coils 22 and armatures 23, each armature controlling one or more contact-operating combs 14. The contact spring pile-ups include the features disclosed in Specification 728,891 in which the fixed springs 10 are first clamped between the insulating spacers 12 and then the moving springs 11 are inserted in recesses provided in the spacers without disturbing the fixed springs. The fixed springs may be adjusted as described in Specifications 728,950 and 734,490, [both in Group XXII]. The armatures are retained on a common knife-edge by a resilient bridge 24 held by screws 25 and coil springs 26 and having pairs of teeth 27 engaging the armatures' sides. Each comb 14 is given an adjustable downward bias by a corresponding spring tongue 17 having a screw 18 threaded into the upper stack plate 15. The coils have different windings and the armatures different sizes, and the several pileups may have differently-functioning contact assemblies, to permit the relay arrangement to perform a number of different duties. Specification 774,539 also is referred to.
