Abstract

6217. Agner, C. M. June 8, 1914, [Convention date]. Automatic telegraphs.-In an automatic transmitter for continuously repeating a wireless distress message, set up, letter by letter, by means of code blocks having conducting and insulating parts, the edge of a power-driven disk 1 is formed with a peripheral groove 28 having inturned marginal flanges 29 adapted to engage grooves 32 in the code blocks 3. The disk has an open part 30 through which the code blocks are inserted in the groove. A conducting-roller 7 is pressed by a spring against the peripheral edges of the code blocks.
