The present invention relates to" web" printing presses and has for an object to pro de a novel arrangement of single impression andrnultiple impression printing-unit's.- p i A particular object'of the invention is top'rovide means for manufacturing a partly colored and partly black and white newspaper.

Another obje'ctof the invention is to provide an arrangement of plates in the printing units such that in a collect product) one section may be printed in" black" and another in black and other colors.

In carrying outthe'presentinvention; I Inay employ an arrangement of printingyunits' sinnlar-to that described in my c operiding'application Serial No. 512,029, filed January 29, 1931; wherein a single color perfectingpress unit is surmounted bya multi-color printingunit; the latter havingone'irnpression cylinder and'ai'plu rajlity of plate cylinders cooperating therewith; so that a Web passing successively through the two units will receiveblack irripr'essions on both faces thereof with color impression onone of said faces.

The present invenuan -reviaes a; mariner or plating twosuch combined units was to produce noveland attractive results.

Other objects and advantages of the present invention will appear in the following' description'of a preferred embodiment and thereafter the novelty and scope of the invention will be pointed out in the claims. I V

The accompanying drawing is a largely diagrammatic side elevation'o'f an embodiment of my invention" illustrating a' typical" plate at: ra'ngement; I

Mounted'on a bed plate"is"aj set'of priming units A and B occupying a 10%? level, wh'fl'e at an upper level "directly above these units are twoprinting un'its'C andD; Thei'unitsAarid B are substantially alikeQ each being a perfecting unit comprising'tw'o p airs of printihg' couple's; The' first'prihting couple is" composed of afiir'n pression cylinder 11 and plate cylinder 12, While the second'couple is composed of animpressi'oir cylinder 13, and plate cylinder" 14'? Each'plate' cylinder isprovided with a novel inking system indicated generally by'th'e reference numeral 15'. A motor 16 is 'mounted'one'ach ofthese' unit's driving the same through a belt 17 running from aspro'cket 18 oh the'motor shaft to a sprocket 19 on the shaft of the impression cyl inder 11;

The units C'and D mounted respectively above the'unitsAand B, are alike, ea'clr'beingadapt ed to print 'aj'plur'ality of colors: Thus, eachof thymus-canen 'ccmprises an impression cylinder 20 cooperating with which are four plate cylinders 21, 22, 23 and 24 respectively. Each of these plate cylinders is provided with its own inkihg 'systefii" 25. of the units C and D is uriyen by the motor 18 directly thereunder through a belt 26' running to sprocket' wh'eel 2'1. The'latter reconnected through a reversing clutch, not shown,"tolthe' impression-wande er:

The webw is] turned'under' the wet 'w by meansofjturning bars 55" and then after passing about "compensating'rol1s56"is e under the ran 57 to" the drag" w and are reds-s aumt to roman; Variatiirisin the 'ai 'nge nt'off multi-color and single-color pages a entrained by'va'rious"arran'gernents of the plate" cylinders of the In thehdrawing; we have shown, "inthe unit A,,printing-plates P on both diametric halves oi theplate cylinder12, while therejis aplate P nj n rpne d ame ric ha idjoi the plate: cylinder. 14. Hence, one face of the web W will receive impressions on successive sections from the plate cylinder 12, While the cylinder 14 will print sections of the other face of the web alternating with intervening blank sections. It will be observed that the web W receives impressions from the multi-color unit on the face which is printed by the couple 13-14. The plate'cylinders 21, 22, 23 and 24 of unit C are each provided with plates on only half of the cylinder and the position of these plates is such as to print only on the blank sections between the parts printed by the plate of cylinder 14. By this arrangement, it is possible to print the web in a single color, say black on one face thereof and on the other face alternately in black and in four colors. Ac-

cording to the plating of the cylinder 14 and the" cylinders 21, 22, 23 and 24 black or color impressions may be placed either on the odd or the even section, as desired. This permits of producing a very attractive product. For instance, four colors may be printed on the first or outside sheet of a newspaper, while the remainder of the paper is printed in black.

The plating of the units Band D is somewhat different from that of units A and C, as illustrated in the drawing. In the unit B the cylinder 12 is provided with two plates P, while the cylinder 14 is left unplated. The cylinder 21 of unit D carries two plates, while the rest of the plate cylinders of unit D carry plates on only half of each cylinder. ,By this arrangement, the web w is printed on one face by the couple 11-12 and then is printed on the opposite face by the couple 21, after which alternate sections, on the face printed by the cylinder 21, will receive multi-color impressions from the cylinders 22, 23 and 24. Thus, the web 1.0 may be printed in black on one face while on the other face sections printed in black alone. will alternate with sections printed in black and three colors. In other Words, the cylinder 21 may beused for printing in black. The usefulness of this arrangement is quite apparent. Should any damage occur to one printing couple of the units A or B, one of the cylinders in the multi-color unit can be used for perfecting in black.

The drawing shows four color cylinders being used for color printing in theunit C and three for color printing and one for black in the unit D, but it is within the scope of my invention to use any number of cylinders up to the limit of the color members as desired. Instead of using all four colors of the color unit, either one, two or three colors may be employed simply by the proper arrangement of plates.

' Having thus described my invention, what I claim as new and desire to protect by Letters Patent is, as followsi V 1. A web printing press comprising, a plurality of plate cylinders adapted to impress the same face of a web, an individual inking system for each cylinder, a printing plate on one half of each cylinder, the plates being relatively positioned whereby one cylinder will print spaced sections of the web and the rest of the cylinders will print in multiple colors in the intervening spaces between said sections. r

2. A web printing press comprising, a plate cylinder adapted to print on one face of a web, and a plurality of plate cylinders adapted to print on the. other face of the web, an individual inking system for each cylinder, a printing plate on each diametric half of the'first-named cylinder, and a printing plate on one diametric half of each of each of the other plate cylinders, the latter printing plates being so relatively positioned that one of them will printo'n alternate .sections of the web andthe rest will print in multiple colors in the spaces between said sections.

3. In a web printing press, a. perfecting press unit, a multiple impression unit comprising a plurality of plate cylinders, means for passing a web through said units, certain of said cylinders having printing plates on only one diametric half thereof, said printing plates being so relatively disposed as to make multiple impressions on alternate sections of the web.

4. A web printing press comprising a single color printing unit and a multiple color printing unit, the single color printing unit comprising a pair of plate cylinders adapted to print'on opposite faces of a web, one of the cylinders having a printingplate on each diametrical half thereof and the other cylinder having a plate on only one dianietrical half thereof to leave blank sec"- tions on one face of the web, the multi-color printing unit having a plurality of printing cylinders each having a printing plate on only one diametrical half thereof, the latter printing plates being adapted to print on said blank sections.

5. A multi-color web printing press comprising an impression cylinder and a plurality of plate cylinders associated therewith, a printing plate on only one-half of each ofsaid cylinders for printing alternate sections of a web, said plates being so relatively disposed that they will make multiple impressions on said alternate sections of the web, and means for making single impressions in the sections intermediate said alternate sections.

6. A web printing press comprising, a pair'of primary plate cylinders, printing plates on both circumferential halves of each cylinder and adapted to print on both sides of a web, a plurality of secondary plate cylinders, printing plates on the latter cylinders adapted to print on one side of the web only, the latter plates covering only a circumferential half of the respective cylinders they are mounted on and adapted to make impressions on alternate spaced sections of the web, said impressions being superposed upon and in register with impressions made by plates on one of the circumferential halves of one of the primary cylinders, and a separate inking mean for each cylinder.

7. A multi-color web printing press comprising, a single impression cylinder and a plurality of printing cylinders associated therewith, print-.- ing plates on said cylinders, and a separate inking means for each cylinder, said plates being so disposed as to print in multiple colors on certain spaced sections of a web and in a single color on intervening sections. 1

8: A multi-color web printing press comprising, a single impression cylinder and a plurality of printing cylinders associated therewith, printing plates on both halves of one of the cylinders and a printing plate on only one half of :each of the other cylinders, the plates on the cylinders being so related that they will make multiple impressions on alternate spaced sections of a web and single impressions on the intervening sections, and a separate inking means for each cylinder.
