Abstract

20,111. Carpentier, J. Nov. 5, 1909, [Convention date]. S e l e c t i v e punching- machines. - In an apparatus of the keyboard type for punching strip for signals on the Baudot system, each key spindle B has a combination of notches corresponding to its letter, and operates the rods d through the arms G, H, A. These rods d are then driven forward by the lever a to actuate the punches X. The belt - driven drum I is mounted loosely on the spindle 6 which is driven from the drum by the steel band 7. This band is attached at one end to the loosely-mounted arm M and at the other to the arm N, which is fixed on the spindle. When the stop Q on the lever R engages with the stop P on the arm N, the band 7 is unbent and loosened and the spindle is not driven. The depression of a key releases the stops P, Q, and the spindle rotates until the stop P strikes the second stop V on the lever R. When the key returns to its normal position, the stops P, V are released and the spindle 6 completes its revolution. During the first part of the revolution the arm a operates the punches, and afterwards the lever arm 13 moves forward the strip feed-wheel k through the arm 12 and pawl l.
