Application filed April 22 1907 Serial No. 369.550.

State of Michigan, have invented certain new and useful Improvements in 'Traveling-Cyb inder WebPrinting Presses; and I hereby declare that the following is afu'll, clear, and exact description. thereof, reference being had to the accompanying drawings, which form part of this specification. Y

This invention is an improvement in traveling cylinder web printing presses of the wellknown duplex type, although applicable to other kinds of presses. to enable two webs to be fed through the printing mechanisms at different speeds, so that both webs may be printed from different forms by the same printing couples, different lengths of each web being printed at each operation of the press, and each web being fed through the press at a predetermined speed and thereafter the products of the two webs can be assembled together. As applied to' presses. of the duplex type, for example, if the cylinders have a travel suflicient to cover two forms arranged one after the other upon the bed, impressions can be taken from both forms on one web and impression can be taken on the other web from a single form placed on the same bed. Thus eight or twelve pages could be printed simultaneously on one web by using a, double set of forms on each bed, and at the same timeaccording to the rapidity of its feed. In carrying out this feature of the invention I preferably make the web-feeding and'deivering cylinders in two sections and provide gearing whereby the .shorter sections of the cylinders which. handle the narrow webs can be run at lower s eedthan the longer sections thereof Whic handle the wide web, so that the narrow web can be fed at the desired slow speed relative to the wide web. I also provide novel loo ing mechanisms whereby each web will e looped at the proper times, in accordance with its rate of its object is.

adapted the narrow web for exfeed and delivery, am le beinglooped only half as fast and to half the extent of the wide webyand preferably both said looping mechanisms are controlled by a single cam in'this invention.

-By-lengthening the throw or travel of the cylinders of anordinary 8-page duplex press I amenabled to print 2, 4, '6, 8, 12 or 16 pa es thereon on a single web, using a-full wi th web and double set of forms on each bed when printing-16 pages, and a narrower web and double arrangement of forms when printing 8 or 12 pages; and when it is desired to print 10 or 14 pages I use a wide web and double set of forms to print 8 or 12 pages,

and a second narrow web and single forms on each bed,

and assemble the resultant product of the narrowweb with the product of the wider web of the folder.

I will now describe the invention with reference to the machine illustrated in the accompanying drawing, in which- Figure 1 represents diagrammatically a duplex press equipped with my novel feeding and delivering mechanisms, whereby two websmay be fed through the press at different speeds. Fig. 2 is a detail sectional view illustrating the construction andmode of gearing the sectional feedin and delivering cylinders, whereby two' we s may be fed through the press at different speeds. Fig. 3 is a detail View of the Web looping devices. Figs. a and 5 are detail-views illustrating the arrangement of forms for printing a ten-page and fourteen-page paper.

in the drawings 1 and to carrytwo rows of type forms, as

indicated in Figs. 4 and 5. 1 and 2 are the cylinders, co-acting withthe forms on said beds, which may be mounted in sliding carriers 3 and reciprocated back and forth of the bed by means of connecting rods 3 operated by crank wheels 3*, as in the duplex? press. The beds and cylinders are preferably arranged "as in the ordinary duplex press and require no detailed description herein as the construction is'well understood. I

Thefeeding-in devices 4 and delivery devices 5 are arranged substantiall as in the duplex press, and the guides and .ooping devices tor handlin the main web are ar ranged; substantial as in the duplex press and need no detailed description; but will bereadily v, understood by following the 2 are type beds bed 2 thence over guide 63 to guide 6 then .down under looping roller 6", then up over guide 6 to the delivery rolls 5. The guides 6 6, 6 6*, aremounted on the cylinder carriers and travel with the cylinders. The looping rollers 6 and 6 are mounted in a reciprocating frame 8, which is operated by means of a link 8 connected to a lever 8 which is vibrated by means of cam 8, as in the duplex press; the parts being operated in such manner that during thetaking of an impression, while the cylinders 1 2 are rolling over the type forms, the web fed in by the feeding rollers is taken up by the ascent of looping roller 6 while a like amount of web is given out by the ascent of the looping roller 6", so that the in-feed and out-feed of the web is continuous, as in the duplex press, and between impressions the looping rollers are lowered so that the loop of web formed over 6 looping roller 6" and enough of the web is shifted forward between the beds and cylinders to bring unprinted portions of the web into position to be printed at the next movement of the clyinders over the fornr The web to, which I will call the slow web,

, is guided similarly through the press but is operated at say half the speed bf web N.

In order to feed and deliver this web w at half speed 1 preferably make the feed and delivery rollers 4: and 5 in sections, as indicated in Fig 2 the fast section 4" of roll a is fixed to the shafts which is driven by a suitable train of gears 4 from the drive shaft at the proper speed to feed the web VJ into the press at the desired speed.

The slow section 4 of the feed roll 4- is rotatably mounted on shaft 4 and is driven, at

say half the speed of section 4", by means of the pinion al on section. 4 meshing witha pinion 41 on the stub shaft 4 journaled in the frame and-carrying a 4S meshing with a gear 4 keyed on the shaft 4*, so that the slow section 4- is driven from shaft 4* at a. much slower rate than section. a The delivery roll 5 is similarly constructed with fast and slow sections 5, 5 which are driven at the same s eed as the sections 4*, l", of the iii-feed ro by means of trains of gears 4 and 4", as indicated in Fig.

By properly proportioning diameters of gears 4 i any desired diifen ence between theperipheral speeds of sections 4*, 4-, can be obtained;

is transferred to the web. This will be readily unde reference to Figs. 1 and 5.

or the draw-- or varying the and where a l narrow web w.

full width web is to be printed, the sections may be driven at the same s eedby substi tuting suitably proportioned gears P, 4

Assuming'that t'wo webs are to be printed, and that the slow sections 4, 5- are geared at half the speed of the fast sections 4, 5*, so

as to feed the narrow slow web 11) one-half as fast as the wide fast web W, it is necessary to provide means for looping the web w in accordance with its slower iii-feed and dc livery. A very simple and effective way-of looping this web is indicated inthe drawin s. As shown, the Web w passes fronra roll uncl er suitable guides over the slow in-feed'section 4 and thence under a iixed guide 7 over a looping roller 7", down under guide 7, and thence over the guide 6 beside and along with the wide web W between the beds and cylinders and as far as guide 6 then the narrow web to passes over a guide 7, down under a looping roller 7', up over a guide 7 to the slow feed section 5 of the delivery mechanism. The looping rollers 7 and 7' are mounted ina frame 9, which is pivotally gears for the I connected at 9 d to ,a lever 9, which is pivoted at 9 to a fixed point of the frame and its forward free end is pivoted to the frame 8, as shown. The ivot 9 is midwaybetween the pivots 9. an '9 and therefore the frame 9 will be moved by and with the frame 8 but will only move half the distance traveled by frame 8, consequently the loo ing rollers 7 7 will only move half the distance of the looping rollers 6", 6 and at half the s eed of the latter, and thus the web w will be coped exactly in accordance with its feed and'delivery, and the one set of looping cams 8 Willi care for both sets of loopers.

From the foregoing it' will be obvious that 'each web will be fed through the press and looped and delivered at the desired speed and in the desired time, and that both webs are practically guided through the press between the beds and cylinders from the guide (5? to y the guide 6 in exactly the same path and by the same means, so that the cylinders will. present both Webs to the forms simultaneously and take impressions upon bothwcbs simultaneously. But, as the narrow web w is fed'more slowly than the fast web W, the forms must be differently arranged and therefore the forms from which the impressions are to be taken on the narrow web must be only half the length. of the forms on whicn the impressions are tobe taken on the wide cod by in g. i the forms 1,3, 5,7, are arranged in tYii 'ows upon the bed i and similarly forms 3 4, 6, 8, are

arranged in two rows upon the l) 1,22, so that itepages will be printed upon t wide web /V while sin le forms and placed upon the beds l and 2 to be p on the This arrangement will give scribed herein.

tions 4 5 will be driven at a 10-page paper with 5 forms on each bed. To printa 14 page paper the forms can be arranged. as in Fig. 5, which shows two rows of forms on beds 1, 2, to be impressed upon the wide web giving '12 pages; while single forms 13, 14, on the beds 1, 2,.will be impressed ,upon the narrow Web.

The arrangement of forms for printing any is led through the press like .web Wabove described, and the looping rollers 7", 7

' will not be used.

- rollers 6 6, will --slow or fast spee By the means claim as new and If it be desired to :handle a wide web through the press at slow speed, it will only be necessary to alter the gearing so as to drive both sections at-the slow speed. Or if desired in order to drive sections 4, 5, at slow speed, like sections 4 5, the sections 4*, 5, can-be unlocked from its shaft 4 by.

withdrawing the keys 4, and'locked to seetions'fA; and 5 in any desired manner, as for instance by a screw 4 engaging a shoulder 4 on section 4 as' indicated in. dotted lines in Fig. 2. larly constructed. This being merely'a matter of mechanical selection and skill I do-not wish to be restricted to any particular construction whereby the two sections of roll 4 and 5 may bedriven alike, at either fast or slow speed. When the sections are driven alike at slow speed, a wide web can be led through'the presslike web w and looping not be used. Thus I can run through this ress a single wide web at or two narrow webs at different speeds.

described I am enabled to print any number of pages desired up to 16 by means of a two bed and cylinder press with a very slight addition members in the ordinary S-page du press, and without any material comp tions in the mechanism thereof. I
