Abstract

748,139. Printing-telegraph transmitters. KLEINSCHMIDT LABORATORIES, Inc. July 6, 1951, No. 12271/53. Divided out of 748,121. Drawings to Specification. Class 40(3). The subject-matter is wholly included in Specification 748,121, but the claims relate to a keyboard transmitter mechanism in which a set of permutation bars selectively positioned by the key levers operate a set of pivoted blocking members to one or the other of two positions in which a corresponding number of contactoperating levers are selectively blocked or not blocked and pivot about one or the other of two axes under control of a rotatable cam member so that a pair of transmitting contacts common to the contact-operating levers are sequentially operated in accordance with the signals to be transmitted.
