Abstract

194,294. American Type Founders Co., (Assignees of Kelly, W. M.). Aug. 6, 1921, [Convention date]. Inking-apparatus.-The forme of a reciprocating bed of a cylinder machine is inked by a series of rollers 92, Fig. 4, mounted in adjustable bearings and ink is applied and distributed to the rollers 92 from a ductor roller 100 by a messenger roller 101 on a vibrating arm operated by cam-and-lever mechanism. The roller 100 is intermittently rotated by cam-operated ratchet-and-pawl mechanism. The messenger roller delivers the ink to a tubular roller 99 between which and the rollers 92 are two lower rollers 97, Fig. 5, and two upper rollers 96 in contact with these, all mounted in a pivoted frame and all driven directly by gearing from the gear 54 which reciprocates the bed by means as described in Specification 184,175. The frame is normally held in operative position with its free ends resting on lugs on the cylinder housings'of the press by arms 104, which can be rotated to hold the frame, in a tripped position. The distributing-rollers 97 are reciprocated longitudinally by the engagement of screwed threads 135, Fig. 5, on their shafts with nuts 136 secured by bolts 137 to the frame 94. By loosening bolts 137 the nuts may be permitted an axial movement which reduces the extent of reciprocation of the corresponding roller 97. The two rollers may thus 'be reciprocated to a different extent, and the distribution and cutting-up of the ink is thus improved.
