With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in form, proportion, and minor' details of construction may be made within the scope of the claims without departing from the spirit or sacrificing any advantages of the invention. I g I For a complete disclosure of the invention, a detail description of a printing machine embodying the invention in a preferred form will now be given in connection with the accompanying drawings forming a part of this specification, wherein:--

Figure 1 is a diagrammatic side elevational View of a multi-color printing press, depicting applicants invention applied thereto;

Figure 2 is a fragmental elevational View showing the multiple printing couples, common drive instrumentalities, and novel web lead; and

Figure 3 is a fragmental horizontal sectional view taken on the line 33 of Fig. 2, depicting the means for simultaneously adjusting both terminals of a compensator roller.

Referring tothe drawings, in which similar reference characters designate corresponding parts, I and 2 indicate the usual side frame members of a multi-color printing machine, and these members are supported by the usual base or bed plate 3. This bed plate 3, in conformity with the usual practice, may be extended at the right, as viewed in Figure 1, to accommodate a folder or a rewinding device, but, inasmuch as these members form no part of applicants invention, they are not here illustrated; A feed 'roll 5 is operably mounted at the'left end of the frame, as illustrated in Figure 1, and the web W from this rollis led' around suitable guide rollers 6, through tension controlling device I, feed rollers 8, and through a plurality of printing couples P.

Each printing couple includes an impression cylinder I2, having a shaft or trunnions I3 suitably journalled in the side frames I and 2 of the machine. A plate or form cylinder I4 has a similar shaft or trunnions I6 suitably journalled in the side frames I and 2, and the plate cylinder coacts with an impression cylinder 52 of each printing couple P. Each plate cylinder, in conformity with the usual practice, is arranged to operably support suitable printing plates, not shown, to which ink is supplied through the in strumentality of the usual inking mechanism, indicated generally at I 8, which distributes the supply of ink from the conventional ink fountain 28 through the intermediation of the usual doctor roller 22. The impression cylinder I2 and plate cylinder I4 of each printing couple may be suitably geared together so that both cylinders operate with the same peripheral speed, but inasmuch as such gearing is in conformity with the usual practice and iswell understood by those skilled in the art, it is not here illustrated.

The printing couples P are preferably positionedabove each other, as shown in Figures 1 and 2, and arrange-d so that their axes actually or approximately coincide with lines or planes radiating from a point located at one side of the machine, for reasons to be hereinafter disclosed. The machine may be driven from any suitable source of power, usually an electric motor, not shown, which drives the horizontally disposed shaft 26 having a bevel gear 27, meshing with a similar gear 28, supported by a vertically disposed shaft 3Il, journalled in suitable bearings 32, carried by the side member I of the machine frame. The impression cylinder I2 of each printing couple P has a suitable gear 34 secured to rotate therewith, and this gear in the present instance is a spiral bevel gear meshing with a similar gear 36, the gears 34 and 35 forming the mating members of a hypoid gear couple.

The radial disposition of the axis of each impression cylinder I2 with relation to the axis of its coacting plate cylinder I4 permits the printing couples P to be arranged so that the impression cylinders of certain of the couples are placed at one side of the vertical shaft 30, and the impression cylinders of other couples positioned at the opposed side of this shaft. In the present arrangement, the upper and lower printing couples P are disposed so that their impression cylinders I2 and driven gears 34 are positioned at the right of the shaft 30, as viewed in Figures 1; and 2, and the intermediate printing couples are disposed so that their impression cylinders I2 and driven gears 34 are positioned at the opposed, or left side, of the shaft 30, as viewed in Figures 1 and 2. By this arrangement, the hypoid gear couples drive the printing couples P in synchronism, and inasmuch as this arrangement permits the plate and impression cylinders of the printing couples to be arranged in radial relationship, an advantageous web lead is made possible. Although any preferred web lead may be employed in the arrangement illustrated, the feed rolls 8 and guide roll 6, positioned thereabove, lead the web W between the plate and impression cylinders. of the lower printing couple, then through the intermediate couples and finally between the plate and impression cylinders of the upper printing couples. From this point, the web may be led to a folder, if the product is to be produced in final form, or, if desired, it may be rewound into a roll for subsequent use. Inasmuch as the disposition of the web after passing through the final printing coupleof applicants device is not a part of applicants invention, the means for rewinding or folding the web has not been illustrated. Although the web W, in the present illustration, is depicted as being led from the supply roll 5, over guide roll 6, through tension controlling devices 'I,to the feeding device 8, it is to be understood that this arrangement may be varied, and, if desired, the web may be led, first, to one or more printing couples to print on one side thereof and then led to the printing components of applicants multi-color arrangement here disclosed.

In order to insure that the impression on the web in passing through each successive printing couple P will register with the previous impression or impressions, a compensator roller 40 is positioned between adjacent printing couples P, as shown in Figures 1 and 2, and inasmuch as four printing couples are here illustrated, three compensator rollers are consequently shown. It is to be understood, of course, that any preferred number of printing couples may be employed in conformity with applicants arrangement, and, in each instance, one or more compensator rollers are operably positioned intermediate adjacent printing couples, and in the relationship herein disclosed. Each compensator roller is provided with a suitable shaft or trunnions 42, joursameness 'tnalle'dr inibearingtzblocksiafl zslidablyvmounted -z in ..:guide.waysa4fisproyidedzin hezzsideimembers-iliand itiof-cthe :machinecframe; :Each'abearing; blockx'fl tisrproyidedtzwith :a ilateral iboss. :aor :lugyfl, :for; the *threadedzifeceptionzoiVia:.threaded:shat s Each shaft 50 is journalled in bearingsifiz iformedtin the sideiframes {I hand-2 iandzimbearingssfiLiforined -inrbracketimembers 5.6:: illhe fbrackets 156: are-:se
