Abstract

17,088. Panter, W. Aug. 23. Ruling-machines -Fig. 1 shows a combined printing and ruling machine, in which the sheets are fed from a table A to movable front stops B, and are taken by grippers on the first impression cylinder G, on which they are printed on one side by a forme cylinder Hand are then taken by grippers on the cylinder I and printed on the other side by the forme cylinder K. The sheets are smoothed on the cylinders H, I by brushes J, J<1>. Printed sheets are then taken off by a gripper cylinder and passed to tapes by which they are carried successively round the cylinders O, P and to delivery rollers U, V, which deliver the sheets as described in Specification No. 15,224, A.D. 1889. While on the cylinders 0, P, the sheets are ruled on both sides by sets of ruling-disks Q, R, S, T, each inked by a roller X in a duct X<1>, driven by a wheel Y from a wheel on the cylinder O or P. The ruling-disks are lifted from the cylinders as required by the parts of the sheets not to be ruled. The forme cylinders may be provided with wood plugs for attaching the printing plates as described in Specification No. 5420, A.D. 1892. The cylinders O, P and parts connected with them are mounted on a sliding frame which may be run out by means of racks engaged by pinions on a shaft 17 to permit of access to the cylinders H, I, &c. The inking- apparatus for each of the cylinders H, K comprises inking-rollers 1, 2 supplied by a drum 3, reciprocated endways by a lever 4. A roller 5 distributes the ink on the drum 3, which is supplied by a roller 6 from a smaller drum 7 supplied by a vibrator 8 from a ductor roll 9. The vibrator 8 is operated by a cam 14, and the ductor roll 9 by a crank-pin on the cam 14, a rod 13, and ratchet gear 12. An additional inking-roller 15 may be provided. The inking-apparatus of the cylinder K may be on a movable frame for permitting of easy access to the cylinder K.
