Abstract

333,522. Fulton, O. Feb. 13, 1929. Copying-telegraphs. -A copying-telegraph. receiver comprises a picture-tracing device 22 and a record-cutting device 21 and means for operating either from the received signals at will. Two rotating drums 10 co-operate respectively with the devices 21, 22 and a switch 25 connects the signals to either or both devices. By connecting the devices in parallel by the switch a picture may be produced on the lower drum corresponding to the recorded signals on the upper drum. According to a modification, a single drum is used, and the devices 21, 22 are mounted on a carrier so arranged that either device can be brought into operation (Fig. 1, not. shown).
