IPC: H04L17/22
Filed: 1928-09-06
Abstract: 297,825. Ateliers J. Carpentier. Sept. 30, 1927, [Convention date]. Electric type-lever machines; platen-shift mechanism; letter-spacing mechanism.-In a telegraphic printing-apparatus comprising a plurality of selector bars 17 - - 21 which select one of a plurality of type bars 25 for operation, an electromagnet 27 controls the striking mechanism and also restores the selector bars to their normal position immediately after striking. Electromagnets 1 - - 5 are energized by signals or combinations of the Baudot or similar system, and each electromagnet allows a corresponding selector bar to be displaced by a spring 22 through the disengagement of an oscillating lever 11 - - 15 from a projection on the under face of the corresponding selector bar. Notches and projections are so arranged on the upper faces of the selector bars that the displacement of one or several of the bars causes only one single row of notches to appear in line with the bars. A drawbar 23 corresponding to the row of notches is operated through a frame 31 by the electromagnet 27, which is energized by the signal distributor through a relay (not shown), the armature of which remains in its attracted position until released by a push rod displaced by the frame 31 at the end of its stroke. After the letter has. been printed the selector bars are restored to their normal position by a lever 40 controlled by the movement of the frame 31. The type bars are arranged in a semi-circle to permit the use of levers 24 and other mechanism usual in such typewriters. Shift to obtain an alternative character on the type bar is effected by displacing a paper-strip guide 26 under the striking point by links 41 actuated by two push rods 42 each con. nected to a drawbar. The paper strip is advanced by a roller 44 which is operated by the movement of the frame 31. The primary circuit of the relay which energizes the electromagnet 27 passes through contacts 43, 44, which are only closed when one or more of the selector bars are disengaged, so that no movement is produced when the apparatus is not receiving signals.
