Abstract
308,070. Marks. E. C. R., (Peck Engraving Co.). March 6, 1928. Inking-apparatus.-Ink is removed from the wiping-strips of an intaglio printing-machine by means of a pad of absorbent material held in contact with the strip as it passes over a roller. The pad 32, Fig. 3, supplied with an ink-solvent from a container 55, is carried by a pair of arms 34 loose upon a sleeve 35 and is pressed against the wiping strip as it passes round the feed drum 27, by a spring 38 anchored to the sleeve and engaging a cross rod 40 between the arms 34. The sleeve 35 is reciprocated upon a shaft 36 by a crank and connecting rod receiving motion from a suitable part of the press. A roller 59 provided with ink-solvent from the container 55 may engage the strip in advance of the pad to effect a preliminary softening of the ink. Solvent and ink particles remaining on the strip as it leaves the pad 32 may be removed by a scraper 65 provided with a trough 6 leading by a pipe 67 to a container. This scraper is carried by pivoted arms 77 and normally pressed against the strip by a spring 78. To facilitate threading of a wiping-strip through the machine, a pair of bell crank levers 75 are provided on a shaft 70 provided with an operating handle 72. The forward ends of the levers 75 lie above a rod 76 connecting the arms 77 and a rod 73 connecting the rear ends of the levers lies adjacent the arms 34 carrying the pad 32. By turning the shaft 70, the scraper 65 and pad 32 can be moved clear of the drum 27. Adjustable side guides 88 guide the strip to the drum 27 and prevent lateral movement of the strip as the pad 32 reciprocates.
