To' a/l/ whom it may cmtccrwf i Be it knownthat I., PAUL FLEMMNG Cox,

bed and cylinder web-perfecting presses; and its Object is to produce apress of sim le construction and high speed, capable o `f `printing newspapers of varioussizes 4up to twelve pages, and which can be constructed to print even larger papers, if desired. y

One subsidiary object of the invention is to shorten the travel of the press-beds by providing two cylinders to coperate'with eachv bed, thereby greatly shortening the travel of the bed, say, one-half, as impressions from one-half of the forms on the bed can be printed by one cylinder, and impressions from the remainder of the formscan be printed by the other cylinder. l

Another object of theinve'ntion'is to kee the parts low down, so that the beds and all parts of the press willbe easily accessible from the Hoor, and the pres'sman canl easily place and make up the forms on the beds, and this low-down construction enables the weight to be kept very close to the base of the press, thereby lessening shock and vibration of parts. 3 f Another obiect is to enable both" sets of forms upon the beds to be inked from one inking mechanism, the complete press requiring but two-ink-fountains instead of four or six. In the complete press one 'inking mechanism is arranged above each bed and between the cylinders coacting therewith, so

that although the press has four impressioncylinders only two sets of inking mechanism are required,

' is the peculiar mode of leading, the .web

or'liis on one bed by one cylinder, I employl through the press, so that impressions willbe.`

State of Michigan, haveinvented certain new This invention is an improvement in {iatu- One of the main features of the invention begun by the first cylinder.' In

two cylinders cooperating with each bed, and lead the web successively between these cylinders andthe bed, and so feedthe web that each cylinder prints from half of the forms on the bed during'the` printing stroke thereof, but during the return stroke a length of web .equal to an impression is fed past the cylinders without being printed, so that the irst cylinder skips alternate spaces of the web, Abut at the succeeding operation of. thepress the secondv cylinder prints inthe blank spaces of the web which are left between the ,impressions produced thereon by the first c linder. i For instance, if the total lengt of forms on the bedbe, say,-thirtyve inches the first cylinder will printA seventeen and one-half inches, and then betweenthe' impressions seventeen and one-half/more inches.

past the first cylin'- printing periods of the second ,cylinder thel seventeen and one-half inches previously printed by the iirstcylinder on the web are fed therepast. Thus for each reciprocation of the bed thirty-live inches of web will be printed and fed between the bed and cylinders, although the bed has only, say, seven# teen and one-half inches of travel during the impression. By this means and-method I am .enabled to print as much web by seventeen and one-half inches travel ofthe bed as could be printed heretofore in an Ordinar single bed and cylinder-press by a thirty-fiveinch travel of the bed. In othgr words, in ,my press the web is printed onone side by one bed and two cylinders cooperating theres,

inder.

Another object of the invention is to keep the web in continual forward motion in the same direction through the press at all times `withbut any reversing or stopping of the web IOO blank spaces left untouched by the iirst cylat any time, although reciprocating beds are used, and this is accomplished by reason of IIO the hit and miss or skip method` of printing upon theweb-above described andusing two vof the web-delivery device.

cylinders with each bed and the fact that the cylinders print only upon one stroke of the bed, and during ,the return stroke of the bed the web is fed forward sufficiently to bringl the unprinted or skipped portions of the web passing the first cylinder of each pair into position te be printed by the second cylinder of each pair at the next succeeding operation of the press.

By reason of the fact that the web is continuously in motion at all times, both during and after printing,- and is always moving in the same direction I am enabled to travel it through the press at high speed, and by reason of the shortness of the travel of the beds`say but seventeen and one--half inches forthirty-five inches of impression or feed of the web-I am enabled to reciprocate the beds .at unusually high speed with safety, and thus I produce a high-speed singlesacting printing-press- Furthermore, in this press the web is so led that no portion of it is carried beneath'the beds or under inking mechanisms. All the web-guides are accessible from the fioor, so the press can be readily threaded, and all parts thereof are open to inspection at all times during the running of the press.

Another feature whereby speed is enhanced is the peculiar arrangement of the type-forms on the beds. Instead of arranging them with the columns extending longitudinally of the bed I preferably arrange them with the columns running transversely of the bed and the pages end to end thereon.A This not only shortene the travel of the bed, but enables me four, eight, or twelve pages from one web and also to split the web ,D and assemble the slit portions of the web before reaching the folder by simply giving each part of the web a quarter-turn over an angle-bar, thus dispensing with the necessity of running webs over a cow-catcher or former before entering the folder. i

I will now describe the invention with lreference to the accompanying drawings, which illustrate a perfecting-pressiadapted to operate upon and embodying the principles of the invention.

Figure 1 is a side elevation of the complete press. Fig. 2 is a diagrammatical longitudinal vertical section of the press. Figs. 3, 4,

' 5, and 6 are diagrams illustrating the method of printing with one bed and two cylinders. Fig. 7 is a diagrammatical view illustrating the arrangement of six-page forms upon the bed. Fig. 8 is a diagrammatical plan view I illustrating how twelve printed pages may be assembled Figs. 9 and l() are detail views Fig. 11 is a` detail view of another crank drive for the beds. Figs. 12, 13, and 14 are diagrams showing the drum-cylinders used with que of the beds.

In the drawings, A B 'represent two hori-- zontal type-beds arranged end to end, preferably in the sanie plane, and suitably mount ed in the ordinary manner upon ways in the main frames of'the press. rl`hese beds may be reciprocated by any suitable iiiechanisin` preferably oppositely to earh other, for the purpose of obtaining a. better balance of the press and as hereinafter deseribed.

Above the bed A and adapted lo eoperale with the forms ,thereon are inun'ession-eyllnders (L and af, which are respectively adapt.- ed to"coperate with the forins l and 2 lying upon the bed A. Similarly, above Il bed are journaled iinpressioircylinders l) adapted to respectively cooperate with forms I:l 2'" ou bed B. The in'ipression-eylinders can be ro tated in any suitable manner, as by being geared to bed-racks, so as to oseillate iu unison with the bed, or they niay be geared lo t ie main shaft and rotated in unison iril h the ed during the printing stroke iu any desired manner. Cylinderdriving gears are so coinmon and well understood that a detailed il lustration and explanation thereof is unnecessary.

The several im)ressioircylinders are provided 'with suitable throw-off mechanism, so that they can be lifted clear of the type dhring the non-printing stroke of the -bed As shown,`they are journaled in eccentric boxes C, which are provided with arms C, connected to a rod or bar C, extending alongside ol' the press and attached at one end to a lever c, pivoted at c on the frame and having a roller c? engaging a cam-groove c" in a cani et. fixed on a shaft c, which is driven by lgears c6 from a transverse shaft e7, driven by bevelgears es from the shaft d2, which extends over and is driven by evel-gears d from the driven shaft D', driven by gears D:x f roui the driving-shaft D, these parts being,r so tiined that the cylinders will be thrown olf impression during the non-printing or return sti-oh es of the bed and will be thrown on impression during the forward or printing stroke of the beds. The bar CE may be disconneetible from the lever c, so that after the cylinders are thrown off impression the bar may be disconnected from the lever and the web-fradin;r devices put out of action, and then the beds can be run to ink up the forms without any printing taking place.

Each bed is adapted to carry forms for four or more pages. rI`hese forms are placed un each bed in two rows, as shown at l and 2 on bed A and at 1fl 2- on bed B. The cylinder n operates on the forms in row 1, a nd the eylinder a operates on the forms in ronat each outward or printing stroke of th'e bed il. Thus two impressions are siniultanecnslA made on the web. On the return stroke no impressions are made, as the inun'ession 4thrown off.

g each bed are inked from a common fountain and inlriug system ais ranged between the miipressnni-eylnuiers.

The forms on Jil IOC

right-hand roller e4 the cylinders c c', respectively, and each respectively supplies ink to one of the forms on bed A. Thus the left-hand form-roller e4 supplies ink to the left-hand form 1. The

supplies ink tothe righthand form 2. A similar inking mechanism is arranged between cylinders b bto supply ink to the forms 122:11 on bed B.

In order to prevent the form-rollers reversing while up he forms, the inking system is constructed so that the form-rollers e4 are suiiiciertly far apart to allow them both .to clear the `forms of type just as the bed comes to the point of reverse', as indicated in Fig. 2 of the dnawings, Where the forms 2 and 1a are shown' clear of' both form-rollers, and. at the dsmpletion of the outermost strokes of beds A and B the forms. 1 and 2a would be in the same position between the lform-rollers e4 that the forms 2 and 1a are shown as occupying. For `these reasonsthe cylinders over each bed are spaced suiiicientlyfar apart to enable the inking mechanism to be inserted therebetween. The forms on each bed are also V'se a'atedsufiiciently to enable the forms tofclear the inking-rollers and the cylinders at the time of reverse.

In order to shorten the stroke of the beds, the type-forms are arranged transversely of the beds in two rows. Thus th forms 1 and 2 may be arranged as in Fig. 7. If printing a twelve-page paper, each row of forms 1 2 and 1a 2a would contain threepages of matter arranged transverselyof the press, and preferably and for further reasons hereinafter eX- plained instead of arranging these forms with the columns running longitudinally of the press I arrange themwith 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 me to materially shorten the travel of the bed, as the forms are of course narrower-than they are long. By this arrangement o'f forms, furthermore, I am enabled after the web is perfected to lslit the web longitudinally and then assemble the papers all together at the folder with a simple quarter-turn of the web, as indicated in Fig.

8. Thus the webs can be slit and pages assembled at the folder without passing them over any former, whereas when the forms are arrangedwith the columns longitudinally of the press, as is ordinarily done, it is necessaryv to pass the web overa former before reaching the folder in order to enable them to be properly cut and collected in the folder. rangement greatly simplifies the construction of the press and facilitates the assembling .of the web.

The web is led in from a roll W, which may This ar-` be conveniently supported above the beds intermediate the two printin mechanisms, as shown in the drawings. T e web is led iirst between the continuously-running'feeding-in rolls G, whichare driven by suitable gearing from the main shaft and at a s eed suflicient to feed the desired length of we say thirtys.

five inches-for each reciprocation of the be The web then passes over a guide-roller g, down under cylinder a, then over guide g above the inking ,mechanism to a guideroller g2., down under cylinder a', up over4 guide g3, then down over guide g4, up over i coaXing-roller H, which may be driven by an suitable means in a direction to coax the `we forwardly or assist its forward travel,

then passed back to and over a second coaxing-roller I-I above the inner end of bed B,

then passed under. a uide h4, up over a guide h3, down under cylin er b, then up over guide h2, back above the second inking mechanism y to a uide k7, down under cylinder /,up over a gulde h, and then to a continuously-running delivery mechanism, which preferably consists of upper and lower web-guiding rollers i t and coacting tapes I, runnin over guide-rollers I I2, and I3, the upper ro lers t" and I3 being intergeared and the upper roller I3 being driven by bevel-gears I4 from a shaft I5, which is driven by gearing from the shaft c7. The delivery devices are adapted to feed the web out of the ress as fast as it is delivered thereinto by t e feed-rolls, and the web is at no time stopped between the feed-rolls G r and the delivery, but runs continuously and in the same ydirection at all times.

If the beds Aand B are driven by a crank mechanism, as indicated in Fig. 1, they have an. accelerated and retarded movement during the printingstrokes, and the web during this time can be compensated for this'irregular movement of the bed by making the rollers g g3 h h3 movable, and, as shown, I mount eac-h of these rollers on supporting-bars 7c, the lower ends of which are connected t0 one arm of bell-crank levers k. The other arms of said levers c are connected to an oscillatory bar k2, -which bar is controlled by means of a bell-crank K', which is pi voted on a fixed support at K, one arm of said bellcrank engaging bar le? and the other arm being controlled by a cam K, which may be located at any desired point; but for convenience I place the same upon one of the beddriving crank-gears J2, hereinafter referred to, the cam being so timed that the rollers g gah 7L willbe slightly raised and lowered during the taking of impressions so as to com-l .pensatethe web for the irregular movement of the type-form during the printing operations without stopping the forward movement of the web. A very slight movement IIS of the rollers g g3 h 7b3 is sul'li cientto compensate the web for the irregular movement' of the forms during the printing operatlon. and

after the printing operation and during the j return stroke of the bed the web can run at i a uniform speed over all of the rollers g but, as stated, at no time, either during or after the printing operation, is the web stopped or reversed, and it is therefore not subjected at t any time to any jerkin@ strains liable to l rupture it.

As indicated in Fig; 2, the beds A and B are operated by pitmen-rods J, pivotally connected at one end to depending studs on the beds and at the other end to crank-pins J on horizontally-disposed crank-gears J2, which intermesh, and to ene of these gears J2 may be secured a bevel-gear J3, which meshes with asmall bevel-gear J4 on a driven shaft D.

The rollers g g2 may be mounted in adj ustable supports to insure proper registration or sequence between the impressions produced on the web from the forms 1 2 by cyl# inders a c', and the rollers 7i h2 may be l mounted in adjustable supports for a like purpose. The coaxing-rollers H `and H may be mounted in adjustable supports for the purpose of insuring registration of impressions between the forms on the beds A and B.

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-.8, and then the slitted portions of the web are led to and over the angle-bars L2, located above the second printingr mechanism, and thus the split sections of the web will be given'a quarter-turn and are assembled and led to a folder, (not shown,) which may be conveniently located i the side of the press. By this arrangement of angle-bars four, eight, or twelve page papers can be printed on one web and the page slit and assembled before passing to the cutting-cylinders and Without the employment of any other formers. Figs. 3, 4, 5, and 6 are diagrams illustrating the method of printing the web by means of two cylinders and one bed. As illustrated in Fig. 3, the bed has just started to the right, several impressions having been made thereon, those marked .fr having been produced by cylinder a and forms 1, and those marked a5 aviog been'produced by cylinder a and forms 2. The blank spaces y between the impressions :t and .r are due to the fact that the web hasbeen fed forward the length of an impression during the return non-printing strokes of' the bed.- During this forward stink-scf the bed (see Fig. 11) another impression :c is being printed by cylinder a and form 1 and another impression is being produced by cylinder c and form 2. At the end ofthe printing stroke (see Fig. 5) the cylnder c has just completed an impression a. on the web from form l, the cylinder a has j just completed an impression from form 2, and there are other impressions in adif'ance able if a very low stroke of the brd iwo ini of and following impro sion :c which as prcviously produced on the web by cylinder a and form 1. As indicated in Fig. (l. during the return stroke of the bed the web is fed so as to bring a blank 'space vy of paper to cylinder a and carry the impressions r a1 away from cylinder a., At the end of the return stroke the Vweb is again in the position indicated in Fig. 3 with a blank space -g/ in front of the cylinder o and ready to be printed thereon at the next operation. lt will bo seen, however, that the cylinders a, a do not print upon the same part of the web, but upon altern ate sections thereof, and the in'ipression from forms 1 and 2 are thus produced upon the web close together and in proper continuity, the impression from form 1 alternating with the impressions from forni 2. The impressions from forms 1 and 2 on the web will be backed up and the web perfected by impressions from the forms lu 2, produced by the cylinders I) in the saine manner. ".lhus, as before stated, the web is fed continuously between the beds and cylinders and thirty-five inches of web are printed at each forward stroke of the beds, although they only vmove seventeen and one-half inches during the taking of impressions on each forward stroke.

While the horizontal arrangement of the crank gears shown in Figs.- 1 and 2 is preferdown press is desired, other arrangements could be used. For ex ample, as shown in Fig. 11, the beds might be driven by means of pit-men M2, connected to crankears M, attached to stub-shafts jonrnalcd in iXed bearings M', arranged in the frame intermediate the beds. Any other preferred form of bed-reciprocating mechanism can be used.

The cylinders shown in Figs. 1 and 2 be oscillatin cylinders, or two or three revolution cylin ers, or stop-cylinders, or drumcylinders, as obviously the particular kind of cylinders employed does not effect the main characteristic of the invention. For exa-1nple, in Figs. 12, 13, and 14 we show a drumcylinder. The periphery of such cylinder would move in the same direction and at substantially the same speed as the web at all times, both during and after impression and upon both strokes ofthe bed.

Gperation: The operation may be summarized as follows: The web is fed in continually by the feed-rolls operated by suitable gearing from the feed-shaft and passes continually between cylinders c a andy bed A, then is led over suitable guides to and between cylinders b and bed B, and is continually delivered, being slit longitudinally and the slit portions given a quarter-turn over the angle-bars and assembled before reaching the folder.
