Abstract

491,044. Type-printing telegraphy. GUNDLFINGER, K. June 19, 1937, No. 17161. Drawings to Specification. [Class 40 (iii)] [Also in Group XVI] In a transmitter-receiver using a standard keyboard having separate keys for numerals and letters, local printing of a transmitted message is effected by providing type bars for all the keys, those for numerals being operated mechanically only. All keys transmit their appropriate codes, numeral codes being identical with some letter codes, but received codes operate only the type bars corresponding to letter keys, numerals being printed on receipt of the shift signal. The numeral types appear on type bars of the numeral keys and also on bars of letter keys which transmit the same code.
