Abstract

311,360. Linotype & Machinery, Ltd., and Jakeman, J. W. Feb. 10, 1928. Cutting-apparatus ; delivery apparatus. - In a sheet-slitting device for a printing-machine in which the sheets are delivered by grippers on a shaft 27 co-operating with a gripper pad shaft 28 carried by chains 25 traversed by sprockets 26, the sheets are cut while the grippers pass over the sprocket wheels by means of a slitting-disc 2 co-operating with a grooved disc 1 mounted on the sprocket shaft 3. To permit of the passage of the shafts 27, 28 around the sprockets, the disc 1 is cut away to form a gap 1<a>, and this gap is adapted to be closed when it comes opposite to the cutting disc, by a plate 5 formed with a groove continuous with the groove of the 1. The plate 5 is mounted on a pivoted member 5<a> carried by a sleeve 7, which is oscillated by sector gears 15, 16 and a lever 17 oscillated by a fixed cam 22 engaging a roller 20 on the lever. As the pivoted member 5a moves circumferentially in a clockwise direction, it is also moved axially against the action of a spring 10 by an inclined cam 14, so that the gap is opened for the shafts 27, 28 to enter. The plate 5 is returned prior to the grippers reaching the slitting-disc 2.
