Abstract

303,046. Linotype & Machinery, Ltd., and Dowson, R. Sept. 27, 1927. Sheet-carriers.-In a rotary printing-machine of the kind in which one of the printing-cylinders, e.g. the offset cylinder of an offset press, is tripped by mechanism operated by a cam 3 on the impression cylinder 4, and the impression cylinder can be tripped by rotating its eccentric bearings by hand- or pedal-operated mechanism. the cylinder 4 co-operates with feed grippers on an arm oscillated by a cam on the shaft of the cylinder, and to prevent the tripping of cylinder- 4 from affecting the feed adversely, the grippers are mounted as described in Specification 287,688 to make their backward and forward movement at different levels., A catch or detent 31 is connected by a link 36 to an arm 33 on the eccentric bearing 15 and is arranged to hold an arm 32 on a shaft 32<a> connected to the means for raising and lowering the grippers, which are held and kept in raised position so long as the cylinder 4 is tripped. The catch can only come into operation when the grippers are in their raised position away from the cylinder 4.
