Abstract

942,146. Carbon paper mechanisms. ALACRA Ltd. Dec. 21, 1961 [Sept. 26, 1960], No. 33013/60. Heading B6F. In a carbon web releasing mechanism which is operated by the carriage-return movement as described in Specification 920,533, two pawls 20 mounted or forming a vertical sliding C-shaped member 19 are arranged for alternate holding engagement with the teeth 18 of a ratchet wheel on the carbon roll shaft. The teeth of the ratchet wheel are at positions which are out of phase in relation to the pawls so the wheel may rotate half a pitch at a time. The member 19 is biased by a spring 23 to an actuating member 25 which is operated by a bell-crank lever 29, 28 when the end 30 thereof engages a stop 31 at the end of a carriage-return movement. The teeth 20 and the ratchet wheel are designed so that the wheel is actually rotated by the interengaging of the two teeth. To effect complete release of the ratchet a crank 35 is operated and both pawls 20 are clear of the ratchet wheel teeth.
