Abstract

348,544. Telegraph transmitters. CREED & CO., Ltd., CREED, F. G., and SALMON, R. D., Telegraph Works, Croydon. Feb. 12, 1930, No. 4738. [Class 40 (iii).] A telegraph transmitter has two peckers, 4, 5, alternately co-operating with two corresponding rows of perforations in a tape, the peckers being each adapted to actuate a corresponding independent detent 10, 11 controlling the clutch 19 of a mechanical relay at opposite points of its revolution, for actuating the transmitting contacts 17, 18. The peckers 4, 5 actuate the detents 10, 11 through bell levers 12, 13 and are alternately pressed against the tape and withdrawn by cams 2, 3 on the rotating shaft 1. The clutch 19 is preferably that described in Specification 344,929, [Group XXXVII].
