Abstract

671,052. Substation equipment. KAELIN, P. June 13, 1949 [June 14, 1948], No. 15645/49. Class 40 (iv). [Also in Group XXXVII] A number - register comprises a cylinder 1 carrying groups of cams 3 pivotally mounted in grooves 2 and movable into their operative position, as shown by cam 3<SP>2</SP>, Fig. 2, by armatures 7 of relays 6 selectively operated by means of a keyboard 22, Fig. 1. Each operation of a key also steps the cylinder 1 by ratchet means, Figs. 3 and 4 (not shown), to bring the next groove 2 into position opposite the armatures 7, so that one cam in each groove is moved into the operative position and is held there by one of the latches 8 secured to spring-urged bars 9. On completion of registration, the cylinder is set in rotation and those cams 3 that are in the operative position close contacts 21 in a sequence corresponding to the registered number. The latches 8 may be caused to release the cams 3 by pressing a ring 13 or 14, Fig. 2, along the shaft 15 of the cylinder to engage a lever 10a or 10b. The device may be used as a numbersender in the telephone substation described in Specification 672,983.
