Abstract
366,023. Counting-apparatus. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- (Schreiber, L. J. J. ; 46, Avenue de Breteuil, Paris.) Oct. 27, 1930, No. 32174. [Class 106 (i).] An electromagnetic counting mechanism of the type used in telephone systems is provided with a single controlling spring for the armature and actuating paw 1 and with a platespring or springs which serve as the pivotal mounting for the armature. The movement of the armature is utilized to actuate contact springs for the mechanism. As shown in Fig. 1, the electromagnet core 18 is mounted on a frame member 14 to which is secured the connecting tag pileup 20 and a thin plate spring 15 that carries the armature 16. To the free end of the armature is attached a non-magnetic plate 2, Fig. 4, formed with a curled outer end constituting a bearing for a member 3 provided with a pawl 5 and an adjustable extension 6 to which is attached an end of a spring 7 the other end of which is secured to a frame member 8 adjustable to vary the controlling force of the spring. The plate 2 has an extension 1 forming a stop pawl for the ratchet wheel 13 of the counter while a frame plate 9 carries a spring retaining pawl 11 therefor. The movement of the armature through a stud thereon effects the operation of local contact springs 19.
