Abstract: 435,030. Printing - machines. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S.; 645, North Lombard Avenue, Oak Park, Illinois, U.S.A.) Feb. 8, 1934, No. 4229. Convention date, Sept. 15, 1933. [Class 100 (ii)] Rotary machines ; inking - apparatus.-A rotary newspaper press of the kind comprising a number of perfecting units consisting of a pair of printing-units with inking drums and rollers mounted in side frames is constructed so as to facilitate transport by making provision whereby extensive disassembly in the factory and reassembly in the printing room is unnecessary. The press is formed of a number of printing-units 1, Fig. 1, and a folding-unit 2 all driven from one main longitudinal shaft 50 supported in bearings 53 and formed with clutches 52 which permit some of the units to be cut out if desired. The printing - rollers 6 and impression rollers 5 are mounted in side frames 8, Fig. 19, in such a manner that these rollers may be readily removed for transport together with their roller bearings and impression adjustments. In use the frames 8 are connected together by tie-bars screwed to them, and they are mounted on base supports 40, Figs. 11, 19, to which are secured by means of screws 132, 136 ink troughs 129 fitted with depending legs 133. The ink fountain roller 140 and two of the ink-supplying rollers 210, 215, are formed at their ends with recesses by means of which they are detachably connected to their driving - gears 220, 221, 224, 230, which are driven from the printing - couples and remain mounted in the frames 8 during transportation, the rollers 140, 210, 215 being dismantled for transportation. The drive to the printing- couples from the shaft 50 is effected by means of vertical drive-shafts 110, Fig. 8, which are coupled to shaft 87 driven by bevel gearing units 55 from the shaft 50. A gear unit 55 is shown in Fig. 17, and comprises a driving-sleeve 70 fitted with a bevel wheel 95 and a driving flange 71 by means of which it is driven from a flange 77 keyed to the shaft 50 and connected to the flange 71 by a shear pin 79. The sleeve 70 is mounted in a casing 60 in such a manner that it can rotate on roller bearings and it can be withdrawn from the casing 60 together with its roller bearings, one set of which is mounted in a detachable cover 73. The bevel gear 95 drives a gear 96 on the lower end of the shaft 87 which is mounted in ball bearings in a detachable housing 84. The shaft 87 drives by worm gearing 86, 100 a shaft 101 which drives the fountain roller shaft by bevel gearing and also operates bell-crank lever mechanism to vibrate the inking-drums 210, 215 in opposite directions. Each shaft 110 at its upper end is fitted with a bevel gear 117 gearing with a bevel gear 118 mounted in a housing 343 fitted with a detachable outer part 115 and an upper-part 342. The gear 118 is connected to a gear 130 mounted by means of ball bearings on a sleeve 125 carried by a stud 120 mounted in the frame 8 and the inner wall of the housing 115. The gear 130 is directly geared to one of the printing-members of each couple 5, 6, which can be arranged so that adjacent pairs of couples will perfect a web in two colours or print one side in three colours and the other in one colour. Gears on the printing-cylinders drive the gears 220, 221, 224, 230, Fig. 17, of the inking-rollers 210, 215 with which coact other distributing rollers 260, 261, Fig. 1. The cylinders 5, 6 are formed with reduced ends which are mounted in the frames 8 by means of roller bearings and detachable sleeves which permit the rollers to be withdrawn with their bearings for transport. The drum 210, Fig. 17 is screwed to flanges 212 on shafts 211, and the drum 215 is similarly connected to its shafts 216. The drum 140 at each end is screwed to flanges on shafts 141 mounted in ball bearings in the frames 8 and driven by the worm gearing 86, 100. Between the drum 140 and the rollers 210, 215 is arranged a messenger roller 180, Fig. 15, carried in arms 183 on an oscillating shaft 184 oscillated from a cam 186 formed integrally with a gear 187 driven from the shaft of the drum 140. The cam 186 reciprocates a spring-urged yoke 194 which is guided by parallel guideways 195 engaged by a guide 196 freely mounted on the shaft of the cam 186. The yoke 194 oscillates a lever 198 freely mounted on the shaft 184, and to adapt the mechanism to rollers 180 of different diameters the lever 198 has an adjustable screw connection with an arm 185 fixed to the shaft 184. Means for lubricating the yoke 194 are provided. The mechanism shown in Fig. 15 is also described in Specification 433,269. Specifications 434,863, 434,864, and 435,082 also are referred to.
