Abstract
345,619. Printing - machines. HOE & CO., Ltd., R., 109, Borough Road, London. -(Hoe & Co., Inc., R. ; 138th Street, New York, U.S.A.) Dec. 19, 1929, No. 38958. [Class 100 (ii).] Inking-apparatus.-In order to improve the distribution of ink, one or more distributing rollers in engagement with a distributing drum, are provided with one or more helical or equivalent peripheral grooves and are driven at a different surface speed from that of the drum. In one form, Fig. 2, two distributing rollers 26, 27 having helical grooves 26<1>, 27<1> of opposite hand, and a smooth distributing roller 28 are driven by pinions 25, 24, 23 from a gear 22 on the shaft of the distributing drum 18 so that their peripheral speed is higher or lower than that of the drum. The grooves 26<1>, 27<1> cause the ink to move longitudinally of the drum 18 but in opposite directions. In a modification, the grooves 26<1>, 27<1> are of the same hand but the rollers are driven by different gears on the shaft of the drum 18 so that one roller is driven at a higher and the other at a lower surface speed than that of the drum. Fig. 5 shows a modified form of roller having short grooves of gradually decreasing depth.
