Abstract
727,190. Typewriters. RHEINMETALLAKT.-GES. Jan. 26, 1953 [May 16, 1952], No. 2263/53. Class 100 (4). Letter-spacing mechanism; carriage-releasing arrangements.-An escapement mechanism for a typewriter, accounting or like machine com. prises a rocker 9 carrying a pawl 10 which is moved into and out of engagement with an escapement wheel 2 alternately with a pawl 13 on an auxiliary rocker 15 pivoted at 14, 141 to the rocker 9. Both rockers 9, 15 are rocked upon the operation of a type key or space key and the auxiliary rocker alone is movable by a release key to disengage the pawl 13. The rocker 9 is mounted on pivots 8 screwed into a support 7 attached to the typewriter frame and the rocker 15 is urged by a spring so that the pawl 13 is adjacent to the pawl 10 and engaging a tooth of the ratchet wheel 2. Upon operation of a type or space key, the rockers are moved, and pawl 13 disengages from the ratchet wheel and the pawl 10 engages with the next. For tabulating, a depending lug 17 of the rocker 15 is actuated to disengage the pawl 13 while the pawl 10 remains in-operative. To effect carriage release, an upward extension 16 of the rocker 15 is actuated from a manual control. During carriage return, the pawl 13 is separated from the ratchet wheel 2 by a wedge 26 frictionally attached to the wheel 2 by a coiled spring.
