The present invention has for its object the provision of a novel and improved printing press particularly adapted for use in the printing of newspapers at high speeds. A further object is the provision of a newspaper printing press having an improved lubrication system which insures constant and thorough lubrication of all bearing surfaces and driving gears. Still another object is the provision of a printing press which can be shipped in a partially assembled state, and can be completely assembled by relatively unskilled workmen.

The invention further provides a novel and improved driving means for the individual printing units, improved bearing adjustment for varying the pressure between the plate and impression cylinders. The invention also provides novel and improved means for reversing one of the printing couples of a unit so that the web to be printed may be perfected or printed in multi-color.

In accordance with the present invention, the printing press comprises a plurality of printing units and one or more folding units preferably arranged in line, each printing unit comprising a pair of printing couplesadapted to perfect a web, andwhich may, if desired, bereversed to print the web invmulti-color. As embodied, suitable driving means are provided for each of said units, and a drive shaft connecting said units extends alongside said line of units. Between each printing unit is provided a clutch in the drive shaft whereby the line of units may be divided at any one or more desired points, and

means are provided for driving the individual units by means of individual drive shafts driven from the main shaft through a coupling which can be silenced at will.

As embodied. each of the units comprises a pair of printing couples, each provided with inking mechanism comprising ink drums arranged in substantially verticahalinement with the plate cylinder of the'couple and driven from the plate cylinder together with the usual inking rollers.

Mean drivenby the vertical drive shaft, are provided for driving the fountain roller and vibrating the inking drums, and other means; driven by the fountain roller, are provided for operating the ductor roll to transfer ink from the fountain roll to the inking rollersand drums and thence to the plate cylinder. k

In the embodied form of the invention, the gearing for driving the vertical drive shaft from the main drive shaft is formed'as a removable unit to facilitate assembly at the printing plant.

The cylindrical body portions of the inking" drums and fountain roller are'preferably provided with detachable flanges and shafts at their ends whereby the drums and roller can be removed without removing their shafts and gears from the side frames in which theyare journalleri... .After removing theserelatively heavy bodies, the cylinders and the gearing units,-the side frames may be shipped with certain of the shafts,.bearings and gears in place, thereby avoiding the extensive disassembly and reassembly hich has heretofore been necessary for shippi newspaper printing presses.

The inking rollers for transferring ink from one inking drum to another and to the plate cylinder are preferablymounted in hangers which receive the anti-friction bearing at the ends of the rollers, and these hangers are preferably 'adapted to pivot abouteither or both of two spaced pivots soas to permit accurate positioning of the inking rollers with respect to both inking drums oran inking drum and the plate cylinder.

Improved means are also provided for varying the pressure between the plate and impression cylinders as may be required for printing.

As embodied, ineans are provided for continuously circulating a relatively large amount of lubricant and for supplying it to the various bearings and gears of theunit, and these means preferably comprise a pump driven by the press and supplying oil under pressure to the various meshes of gears near the top of the unit and to the heavy bearings, as well as other means for receiving the excess oil from the gears and bearings and leading it to the other lighter bearings and operating under relatively Referring now in detail to the illustrative embodiment of the invention as shown in the accompanying drawings} the printing press comprises a plurality of printing units l which may be of identical construction and are arranged in line with each other to supply the webs printed by them to a folding unit 2, also in line with the, printing unit. Any suitable number of printing 7 units I and folding units 2 may be employed, with the-folding units preferably interposed between the printing units.

The folding units 2 may be ofconventional construction comprising the usual former 3 and O transverse folding cylinders 9, adapted to associate, longitudinally fold, cut, transversely fold and printed by the printing units i.

deliver as separate products the various webs The printing units I each comprise a pair of v Bearings 9 are held withintheir sleeves It) by means of flanges H and I2 which are bolted to the opposite sides of sleeves 10, while sleeves J0 are held against angular or axial movement by means of screws I3 passing through the flange l4,"

integral with sleeve l0, and threaded into the frame 8.

Cylinder 5, cooperating with the st or second impression cylinder 6 to form the rear couple of the unit, is likewise mounted in the frames 8 by means of its projecting shaft ends l5 on which are mounted roller bearings I6 seated in eccentric annular sleeves l l, and. retained, therein by means of flange I8, at the right, or by a capping plate 19 at the left end.

The

cylinders

5 and 6 of the forward printing couple are mounted in a manner generally similar to those of the rear couple, except that in the illustrativeembodiment one end of cylinder shaft l is'covered by means of a plate 19 which also serves to hold the end bearing 9 in place, whereas in the rear couple the cap I9 is applied to the left shaft end 15.

At one end of the cylinders, the bearings 9 and iii are held apart by means of a spacer ring 20 positioned between the outer races of the bearings and. are a sliding fit in their supporting sleeves,

whereas at the other end of the cylinders the bearings are held apart by spacing ring 2| positioned between the inner races of the bearings and are a press fit on the cylinder shaft. At the ends, the inner bearings abut against the ring 22 fitted to a shoulder of the shaft 1 or IS. The inner race of the outer bearings 9 or I6 is pressed inwardly by means of a spacer ring 23 fitted closely to the shaft and extending between the inner race and an abutting gear or capping plate.

Means are provided for varying the pressure exerted during-printing between the'plate cylinder '6 and impression cylinder 5,"anH' for this purpose eccentric sleeves I! may be minutely sition. 'As embodied, each sleeve i7 is provided. with a pair of diametrically opposed radially extending ears 2% which project into a corresponclin ly enlarged portion 25 of the frame re-' angularly moved to and held in any desired pog
