Abstract: 322,870. Jardine, Ltd., J., and Ball, H. J. Nov. 16, 1928. Platen rotation for condensed billing &c.-The platen is rotated backwards and forwards to deliver a typed bill and feed in a new bill by means of two pawls pivoted on a hand-level and cooperating with oppositely toothed ratchet-wheels on the platen shaft, a stationary cam at the side of the ratchet-wheels causing the advancing-pawl to impart a greater movement than the returning-pawl for the purpose of line-spacing the record sheet. The mechanism shown in Figs. 2 and 3 is mounted as a unit on a sleeve A secured to the platen shaft, and comprises oppositely toothed ratchet-wheels D, E secured to the sleeve and co-operating with pawls S, T pivoted on a hand-lever J revoluble on a loose sleeve G to which are secured a disc H and a cam F. The hand-lever is provided with a stop J<1> for engaging a stop M on the disc H, and an adjustable arm K provided with a pin K<1> for engaging holes H<1> in the disc, engagement being maintained by a spring L. The disc is coupled to the carriage by means of a stud 0 having a flat engaging a flat on a stud P on the carriage, a collar V being arranged over, the flats, and the stud P having a spring pin engaging a recess in the stud 0. The cam is formed with two steps F<1>, F<2> for engaging a roller S<1> on the pawl S, and the pawl T has a finger T<1> extending over the pawl S. When the hand-lever is moved forwards, the pawls S, T drop in succession into engagement with the ratchet-wheels D, E and the pawl S turns the platen backwards through an arc determined by the arm K. On return of the hand-lever, the pawl T turns the platen forwards and, since the pawl is not released until the roller S<1> engages the step F<2>, the forward arc is greater than the backward arc, the difference being equal to two line-spaces. To permit of the platen being moved nearly two revolutions, the collar V is moved to release the stud 0. To permit of the platen being moved nearly three revolutions a second disc is interposed between disc H and the carriage and is coupled releasably to the carriage and the disc H in the above-described manner.
