To all w iz/m, it may concern:

' Be it known that 1, PAUL FLEMMING Cox, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Printingiresses; and I hereby declare that the follow ring is a full, clear, and exact description tl'iereof, reference being had to the accompanying (iYi-LWJHgS, which form part of this specification.

This invention is an improvement in web printing presses in which erfected impresone are produced upon t e web from fiat forms. of type by moving impression-cylind s and its princi al object is to shorten the travel of the cylin ers approximately half or ess. 1 In other words, where stationary beds are used andtwo sets of forms are arranged on each bed the cylinder will have to travel but the length or Width of one form instead core, and this is accomplished by providing two cylinders to operate upon each bed and separating the forms. on such beds into spon only one part or half of the forms on such bed, the cylinders operating, preferably, simultaneously upon the formsone cylinder nd. its half-form printing parts of the web rnt The two cylindiirs and" their forms, lowever, make their impressionsupon the ch in close juxtaposition, so that theefl'ect the same as if both forms were printed by ne cylinder traveling over both forms. By ins shortening the travel of the cylinders re speed of the press is proportionately in- .ased.

Further jobjects oi" the invention are to ake the press very low down, so that the .ds and allparts will be within easy reach of e o orator and the forms can be readily mace on or removed from the beds.

The presentinvention also enables such a crass to produce papers of large size from a ogil. ab and dispenses with the necessity sing formers at the i' older, the web can '3 slitted longitudinally into page lengths 1 .(l assembled before reaching the folder or 1 "a ittii ig-cylinders.

The invention is illustrated in the accomanying drawings, which show one practical Torin of web-perfecting printing-pross emidying the invention and is summarized in .laims following the description of such .he length or width of both forms here-' no parts and having each cylinder operate pped by the other cvlinder and its half In said drawings, Figure 1. is a side elevation of the complete press. Fig. 2 is a longitudinal section through such press. Figs. 3, 4, 5, and 6 are diagrammatical views illus' trating the method of printing the web. Fig. 7 is a detail view showing the arrangement of forms on the bed. Fig. 8 is a detail section on line 8 8, Fig. i. Fig. 9 is a detail plan view illustrating the meth od of splitting and assembling the webs.

In the drawings, A B represent two horizontal typebeds, arranged preferably in the same plane and securely bolted in the ordinary manner to the main frames of the press.

Above the bed A and adapted to cooperate with. the forms thereon are impressioncylinders a and a, which are respectively adapted to cooperate with the forms 1 and 2 lying upon the bed A. Similarly above bed B, are journaled impression-0ylindcrs b 1),

adapted to respectively cooperate with forms 3, as shown.

The several impressioncylinders are pref during their.non-printing strokes, and, as shown, the cylinders in each pair are journaled in eccentric-boxes C, which are provided with arms (7, connected by a rod or bar C extending alongside of the press, and each box also has an arm 0, carrying a roller adapted to engage cams c on the main frames, as imlicatcd, those parts being so constructed that the cylinders ill be thrown o lf impression during their one stroke or travel of the cylinders and will be thrown on impression during the forward or printing stroke of the same. The cams may be disccmnectiblo or adjustable, so that the cylinders can be thrown off impression and the web-feeding devices put out of. action, and then the cylinders run to ink up the forms without any printing taking lace.

As indicator-l in Fig. 1, t 1e cylinder-carriers 3 3 are operated by pitman-rods. J,

pivotally connected at one end to studs on the cylinrlcr-carriers and at the other end to i crank-pins J on mam crank-gears J which intermesh, and one of these gears J meshes with a small driving-gear J on the shaft 1", to which power is applied in any known manner. Each bed A and B is adapted to carry forms for four or more pages. These forms are preferably placed on each bed in two rows, as shown at 1 and 2 on bed A and at 1' 2 on bed B. The cylinder (1 operates on the forms in row 1 and the cylinder a operates on the forms in row 2 at each outward or printing stroke of the cylinders a a. Thus two impressions are simultaneously made on the web. On the return stroke of cylinders a, a no impressions are made, as the impression is thrown ofi. The cylinders over each bed are spaced sufiiciently far apart to enable the inking mechanism to be inserted therebetween'. The forms on each bed are preferably inked from a common fountain and inking system arranged between and traveling with the impressioncylinders. Thus the forms on bed A may be supplied with ink from a fountain E by means of the ductor-roller e, drum 6, distributing-rollers e e ,-and form-rollers e c, all mounted on carriers 3. The form-rollers 0 lie near the cylinders a a, respectively, and each respectively supplies ink to one of the forms on bed A. The left-hand form-roller e supplies ink to the left-hand form 1 and the righthand roller 6 supplies ink to the righthand form 2. A similar inking mechanism is mounted on carriers 3' between cylinders b b to supply ink to the forms 1 2 on bed B.

In order to prevent the form-rollers reversing while upon the forms, the cylinders and form-rollers c are sufficiently far apart to'all'ow the rollers to clear their related forms the point-of reverse, as indicated in Fig. 2 of the drawings, where the form-rollers are shown as clear of both forms 2 and 1*, and at the completion of the innermost strokes of the pitmen the form-rollers would be in the same position between the forms 1 and 2 that the forms 2 and 1 are shown as occupying. The forms on each bed are also separated.

sufficiently to .enable the forms to clear the inking-rollers and the cylinders at the time of reverse. I

In order to shorten the stroke of the cylinder-carriers, the type-forms are preferably arranged transversely of the beds in two rows, as indicated in Fig. 7. .[f printing a twelve-page paper, each row of forms 1 2 and l 2 -would contain three pages of matter arranged transversely of the press, and preferably, for reasons hereinafter explained, instead of arranging these forms with the columns running longitudinally of the press we arrange them with the columns running transversely of the press, so that instead of the column-forms being side by side they are end to end, as indicated in Fig. 7, and this enables us to materially shorten the travel of the reciprocating impression-cylinders, as the forms are of course narrower than they are long. This arrangement of forms enables the web after being perfected to be slit longitiulinally and the papers assembled at the folder with a simple qm'irterturn of the split web, as indicated in Fig. 9. In this way the webs can be slit and the pages assembled at the folder without necessarily passing them over any former, which arrangement greatly simplifies the construction of the press and facilitates the assembling of the web.

The web is supplied from a roll W, which maybe conveniently supported at one end of the press, as shown in the drawings. The web is led in under an idler 5. then between the continuously running feedingin mcchan ism, comprising a roll G, mounted upon and around the shaft J of one set of gears J, and

a series of tapes G, coacting with roll G in the usual manner, the tapes being guided over idlers and provided with suitable tensioning devices. The roll G is of such diame ter that it will-feed the desired length of web say thirty-five inches-for each reciprocation of the cylimler-carriage. The web then passes over a guide-roller g", then around a fixed guide-roller then is looped around a looping-roller 6 and passed around a fixed guide 16",.and thence passes to and over a guide 9 and down under cylinder (1., then over guide 9 and above the inking mechanism to a guide-roller 9 down under cylinder (1/, up over guide g, then under and over a guiding andcoaxing roller g. The guides g g g g are mounted on the carriers 3 and travel with cylinders a a, and guides b h 71 h are mounted on carriers 3. The guides 16 r) may be rotated by any suitable means (not shown) to coax the web forward. Guide g is shown as mounted in the upper ends of pivoted levers 7, which can be adjusted to move the roller '9 in or out. From guide 9 the web passes back to and over a guide it" on carrier 3*, then down under cylinder 1), then up over guide if, back above the second inking mechanism to a guide It, down under cylinder 1),

up over a guide It, thence around a second rolls.

The rollers g or g may be mounted in adjustable supports on the carriers to'msure proper registration or sequence between the impressions produced on the web from the lever 6 pivoted at 6 on the frame and havby roll .l. 'lhewebmay be slit longitiulin'ally forms 1 2 by cylinders a a, and the rollers h or it may be mounted in adjustable supports for a like purpose.

l The looping-rollers 6* 6 ma be, as shown, mounted on opposite ends 0 reciprocatory bars 6, which are operated by means of a ing rollers on their lower ends engaging racecams 6 on the shaft of one of the crank-gears J thecam and levers being so 'proportioned as to move the rollers in one direction during impressions and in the opposite direction between impressions, so that the roller 6" takes up the web fed in by the feed mechanism during impressions, while roller 6 gives up a like amount of web to the delivery mechanism. After impressions the reverse movements of the looping-rollers shifts part of the web through the pressroller 6" taking up in its loop the web given out of its loop by rollers 6", the coaction of the looping-rollers with the delivery mechanism after impressions suiiicing to shift the desired length of web. through the press after impressions. Any-other desired means for feedin and shifting the web-may be employei I After the web has been perfected it is divided longitudinally by slitters L, which. may be conveniently located adjacent to the roller t the web being slitted longitudinally,- as indicated in Fig. 9, and then the slitted portions of the web may be ledto and over angle-bars L located above the second printing mechanism and given a quarter-turn thereby and then assembled and led toa folder, (not shown,) which may be located at the side of the press. By this arrangement of angle-bars'difi erei'it sized papers can be printed on one web a'nd'the pages slit and assembled before passing to the cuttingcylinders and folded without the'employment of formers.

Operation: The operation may be summarized as follows: The web is led in continually by the inleed-cylinder G- and alter being loo ied aronndroller 6" is passed be tween cy inders a u"and bed A, then is led over suital'ile guidesto and between cylinders I) b and bed B, and then led over suitable guides to and looped around a second looping-roller 6", and is continually delivered and theslit portions given a quarter-turn over the tltil(i-2LFS and assembled before reaching the folder. At each printing-stroke oi' the sets. of cylinders two impressions are produced on the web by the eoaction ol' cylindersd a. with the forms 1 and 2 on bed A and a similar number of impressions are printed on the opposite side of the web in register with the first impressions by ylinders I; htcoacting with forms I 2 on bed B.

' curing two cylinders with each bed I am able to and bed, as above explained, the web being 1 ed as hereinafter described. The first cylin-' .der ((0 or 1)) in each pair, however, skips every other page-width of Web; but these skipped portions are printed by the second cylinder in each pair, which skips the previouslyglprinted portions, the ski ping oc-.

uring the return stroke 0' the cylinders and while the impression is thrown ofi". The press, as shownin Fig. 1, has just cornpleted a printing-stroke and the impressioncylinders have ust been thrown off of impression and will at once commence their return nonprinting stroke to their inner or central position, the sets of cylinders are preferably arranged to move oppositely. While the cylinder-carriages are returning "ofi' impression, the looping-roller 6 will travel to the left, its loop being exhausted by the action of the other looping-roller 6*, which travels in unison therewith, (both rollers being moved simultaneously in the same direction by bars 6,) and the required amount of web will be transferred or spaced forward to bring the desired spaces of the web into proper position to be printed on the next printing-stroltc of the impressioiH-ylin- (icis. Just as the cylinders.impinge the. web against the forms the looping-roller 6" commences its travel to the right, taking up the amount of web fed in by roll (it wliilethe impressiorncyliriders are in impression, while the other spacing-roller ti" recedes to the right at the same speed,supplying the demands ol' the delivery-roll if during the printing operation, thus preserving the tension of the paper and having all the time of the return or non-printingstroke of the cylinders to readjustthe. web in readiness for a repeated operation, the spacing-rollers transi'erring the regular amount; of paper while the traveling cylinders are-oil impression and returning out of contact over the typeforms. 'lhis enables a very easy acting cam 6* to be employed and insures a high speed witlisafet-y and without undue jerking of the web.

l igs. 3, -l, 5, and 6 are diagrams illustrating the method of printing the web by means of two cylinders owrating on .one bed.

Fig. 2% shows the cylinders just ready to begin the printing-stroke, no impressions having been made on the web, which is now stationary.
