To all whom it may concern.-
Be it known that I, JOSEPH L. COX, of Bat tle Creek, in the county of Calhoun and State of Michigan, have invented certain new and usefullmprovementsin Printing-Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and
to the letters of reference marked thereon, which form part of this specification, in which- Figures 1 and 1 representasideelevation of my improved printingpress. Fig. 2 is a detail sectional view through one end of the carrier-frame cylinders,-&c. Fig. Sfis a detail face view of the cam devices for operating the looping-frame. Fig. 4: is a diagram-section through the press, illustrating the course of the paper-web. Fig-5 is a sectional detail of the inking devices. Fig. (3 is a detail.
The present invention is an improvement in printing-presses, and relates especially to web-printing presses wherein the printing is effected on a continuous webprevious to severence thereof into sheets; and the present press is a combined type-bed and cylinder press of simple and economical construction, capable of being run ata high rate of speed, and which can be employed with equally good effect either as an ordinary single-bed press or as a perfecting press for books, newspapers, &c., and wherein the register of the impressions on opposite sides of the sheets can be quickly and accurately effected without any necessary alteration or adjustment of the impression-cylinders or type beds or forms.
Another object is to avoid the use of guide and supporting tapes for directing the web through the press.
The invention consists, essentially, in a press having two type-beds arranged one above the other, whereon ordinary forms of type can be placed and used in printing, and on both beds the type rest face uppermost and point in the same direction and coacting with revolving impression-cylinders mounted in reciprocating bearings, whereby the cylinders are moved back and forth over the beds, producing a fresh impression during each stroke or movement either forward or backward.
The invention further consists in novel mechanism for conducting the web from the paper-roll above the forms on the type-beds and'beneath and partly around the impression cylinder or cylinders for feeding the web continuously into and delivering it continuously from the press, yet. stopping that portion of the web which is being imprintedduring the time the cylinder is traveling over the form in making an impression without stopping either the-feed or the delivery of the web, and for immediately feeding it forward upon the completion of the impression sufficiently to bring a fresh portion of the web into position for beingimprinted by the return stroke of the impression-cylinder without lessening the tension of the web at any time.
The invention further consists in novel means for inking the forms previous to tak- 7o ing an impression; means for looping the web between the feed-rolls and type-bed and between the type-bed and delivery-rolls and for properly maintaining its tension, and also to permit different lengths of sheets to be 7 printed without altering the speed or stroke of the cylinders.
The invention consists, finally, in novel supporting and operating mechanism for the impression-cylinders and form-rollers, and in So certain other novel details of construction and combination of parts, as will be hereinafter more clearly described and claimed.
Referring to the drawings by letters, Adesignates the frame of the press, and B a shaft journaled in proper hearings in the frame near one end thereof and carrying on its outer ends crank-wheels B. On one end of shaft B is keyed a large gear, or the periphery of wheel B may be toothed, as at B 0 meshing with a small pinion I), mounted on a stub shaft 1), journaled in the side of the main frame, and a bracket attached thereto and having a pulley b on its extremity by which it can be driven by belting from any 5 suitable source of power. At the opposite end of the machine and in the same plane as shaft B are guides or grooves A A, formed in the sides of the main frame, and in these guidesrest guide-lugs c c of carrier-castings 0C, which support the impression-cylinderof the press, hereinafter referred to. TE
carriers 0 are connected by transverse rods 0 as indicated, to constitute a kind of carriage and retain them in the guides A. Each carrier 0 has an outwardly-projecting gudgeon c, to which is connected one end of a pitman E, the other end of which is secured to a wrist-pin e of the wheel B at thesame side of the machine, so that when said wheels are rotated carriers 0 Care reciprocated horizontally back and forth in guides A. The carriers have depending portions 0 in which are formed journal-bearings for the shaft of an impression cylinder H, which travels over the surface of a type-bed h, fixed in the frame below guides A, as indicated, and on which an ordinary type-form can be placed and secured. From each side of portions 0 project in opposite directionslateral arms 0 in which are formed bearings for webguide rollers F F, lying parallel with the cylinder,
and the extremities of these arms are slotted, as at 0 and in these slots are retained and journaled the gudgeons g g of inking-rollers G G, which are thus allowed a slightamount of vertical play, for a purpose hereinafter 'shown. Above arms 0 are short arms C in the extremities of which are formed bearings for the journals of web-guide rollers ff. As shown, a second type-bed h is mounted in frame A directly over bed It and above guides A, so as not to interfere with the reciprocation of the carriers, and from the carriers rise upstanding portions 0 having laterally-projecting arms 0 0 (corresponding to the portion C and its arms C 0 and in portions 0 is journaled the shaft of an impression-cylinder 11, similar to cylinder H and traveling over bed h, and in arms (3 are journaled web-rollers F, and their extremities are vertically slotted to receive the journals of inking-rollers G G, similar to rollers G.
I In arms C are journaled web-guide rollers f. The arrangement of cylinders and rollers on the upper and lower portions of the carriers is identical.
Onone end of each impression-cylinder is mounted a gear H which intermeshes with a rack Hiattached to the main frame beside the type-beds, respectively, by which a positive rotary motion is given to the cylinders as they are reciprocated back and forth over the type-beds. At the outer or rear ends of each type-bed h h is an ink-cylinder or distributing-roll I, mounted in proper bearings formed in or attached to the main frame, and I I are inkfountains of ordinary construction mounted on the end of the main frame exterior to said rolls.
I I are ductor-rollers mounted in swinging arms l fixed on shafts W, journaled in the main frame near the rear end of each type-bed, and W are crank-arms attached to. the ends of shaft- W and connected by alinkrod W so that the shafts W will rock synchronously.
main frame.
I designate upstanding fingers fixed on the outer end of thelower shaftW and adapted to be contacted by studs w on the lower rear arms of carriers 0 and rocked outward,there by oscillating shafts W and throwing the ductor-rollers into contact with the fountains, and as the carriers move inward the ductors drop inward by gravity, aided by springs, if desired, and deliver ink to rolls I.
If desired to reciprocate the ductor-rollers between the fountains and ink-rolls when the carriers are at the inner end of their stroke, I propose to use fingers I pivoted to the main frame below the carrier when at theinner end of their stroke and which project into the path of and are forced backward by the studs 10. rods 1 with crank-arms w on shafts WV and impart an oscillatory movement to said shafts and arms 1 and thus oscillate the ductor on both the forward and return stroke of the impression-cylinders, or carriers.
I designate distributing-rollers coacting with and against rells I I to disseminate the' ink thereon.
Mare ink-rolls similar to rolls I, but mounted in the main frame in proper bearings at the inner ends of beds h h and in same horizontal planes as rolls I I and t are ink-disseminating rollers coa-cting therewith.
i 2' designate,-.rollers smaller than rolls I i and lying parallel therewith, but depending slightly below the same and at the sides thereof opposite the bed-plates, and t i designate endless belts running over the rollers i at the opposite ends of the respective type-beds andcontacting by their upper sides with the ink rolls I a, respectively, and transmitting or carrying ink from rolls I to rolls i, th usenabling me to ink both rolls from a single fountain. On the ends of the inner rollers i or their shafts are pinions 2' which intermesh directly with gears J on the end of a transverse, shaft J, journaled in the main frame between rollers 2' and shaft B, or are driven from said gears J through intermittent traips of gears mounted on stub-shafts fixed to the sides of the main frame. Gears J in turn are driven either by directly intermeshing with or by trains of gearing from gear B? on shaft B. I
Above shaft J and almost in the same plane as guides A are arranged three calender-rolls K K K mounted in properly-adjustablejournal-boxes secured in slots in the side of the On the shafts of these calenders are intermeshing similar pinions, by which the calenders are equally and properly speeded, and motion is imparted thereto by means of a gear K mounted on the shaft of one of the calenders and meshing with one of the gears J, as shown. v

Above the looping-frame and at the side thereof adjoining carriers 0 is. a web-guide roller M, mounted in brackets attached to vertically-upstanding nearly-central portions A of the main frame, and vertically below roller M and below the loopingrollers is another web-guide roller M, and atthe outer end of the press in the same horizontal plane and parallel with roller M is a guideroller m, and vertically above roller m is a guide-roller m. Rollers M m are in the same plane with each other and with the guide-rollers f f of carriers 0', and rollers M m are in the same plane as the guide-rollers f f of the carriers and are preferably mounted in adjustable bearings. Above thelooping-frame and journaled in the upperportion of part A of the main frame is a delivery-roll 0 and other rollers and tapes, which coact therewith to draw the web and deliver it afterimpression out of the machine, o'r,as I prefer to arrange it, to a folding apparatus combined with the press and mounted in portion A and above shaft B,'but whichI do not herein claim nor consider description thereof necessary. The roll 0 is driven at proper speed by a train of gearing 0 0 from the gear K V PP designate levers connected to the inkfonntains and each other and suitable mechanism by means of which they can be shifted to cut off the supply of ink when desired, and the rollers 2' can be adjusted toward or from rolls I 2'; but these latter mechanisms do not form indispensable elements of present case and can be of any convenient construction.
'-, .It will be noticed that the type-beds are arranged parallel and one over or directly opposite the other, but that the type forms or plates thereon face in the same directiont'. e.., the type 011 one bed is opposite the back or bottom of the opposite bed; also, that one impression-cylinder reciprocates between the type-beds and the other reciprocates outside of the upper bed or one cylinder lies between the type-beds and one type-bed lies between the cylinders, so that I can use ordinary type with perfect safety in my perfecting-press, thongh'it is equally well adapted to printing from plates. The course of the web isas follows: The web of paper is taken from the roll to the calenders, and fed up between the first and center calender and over thelatter down between it'and the third, then up over the lower compensating loop-roller Z, thence down under roller M and to and over the'roller f on the adjoining side of the carriers 0, thence down under the roller F at the same side of the carrier, then forward beneath impressioncylinder H to andunder roller F at the opposite side of the carrier, thence up over the other roller f, and then outward to the roller m, under which it passes and is led up over the roller m and then back to and over the upper roller f on the upper portion of carriers 0, down under the roller F at the same side of the carrier, inward under impression-cylinder H and opposite roller F. and up over the other roller f to and over roller M, and then down under the upper compensatingloop rollerl and up to the delivery-rolls, as shown. The web thus makes a complete return in the press, passing under both cylinders H H and looping around the same, and the upper and lower portions of the main loop of the web lying, respectively, above the type-beds h h. A roller P may be arranged at the rear end of the press, between rollers M m, to regulate the tension of the web, if desired.
The parts should be speeded, for instance, about as follows: The calender-rolls should have a peripheral speed sufficient to draw from the paper-roll and pay out enough web for an impression or one sheet for each one-half revolution of shaft B, and shaft J should be so speeded by the gearing that it will make two revolutions for each revolution of shaft B or one for each length of paper fed in by the calender-rolls, and the delivery-rolls should be so speeded'that they will feed out and draw through the press exactly the amount of paper-web fed therein during a given time by the calenders, so that the amount of web fed into and paid out of the press in a given time will be identical. Say, for instance, that the length of form to be printed is twenty-four inches, and the amount of paper to be fed in for each impression, allowing for margin, is twenty-six inches, for each half-revolution of shaft B twenty-six inches of web must be fed in by the calenders andtwenty-sixinches paid out by the delivery mechanism. The
type-bed and type, as before stated, are sta tionary, and for each revolution of shaft B the impression-cylinders H H on carriers 0 are moved once forward and once backward over the type on beds h h, making an impression at each movement or two impressions on each side of the web for each revolution of shaft B. The portion of the web between rollers M m and M m must be at a standstill during the taking of an impression.
To more easily explain the operation of taking an impression, consider this portion of the web stopped entirely, and yet shaft B moving. The carriers 0 are moved in one IOC IIO
of an impression.
direction over 'thetype on the bed, and this pression-cylinder travels with the cylinder,
the guide-rollers at one side of the cylinder directing the loop of web down between the type and cylinder and the guide-rollers at the opposite side of the cylinder immediately lifting the web from the type, so that when the cylinder has passed over the type the web has been imprinted and lifted clear from the type. Yet its position is unchanged, and it is then necessary to move the web forward the proper distance before the return stroke of the carriers in order to make a new impression on a fresh portion of the web during such return stroke. It will be noticed that the web is being all the time fed into the press by the calenders even during the taking Hence arises the use and necessity for the looping-rollers. The cams are so constructed and mounted on shaft J that at the proper time during the movement of the carrier the looping-frame begins to rise, and the extent of stroke of such frame is calculated to be one-quarter the length of the sheet of paper paid in by the calenders. This being, as supposed, twenty-six. inches, the
stroke of the looping-frame would be about at the inner end of its'stroke, the parts are so timed that the instant the.impression-cyli der reaches the type the looping-frame begins to rise with such speed that all the web fed in by the calenders while the impressioncylinder is on the type is taken up in forming the lower loop over roller I, so that no web is fed forward past roller M, and at the same time the upper loop formed by roller Z is paid out with equal speed, so that the upper and lower loops containing an equal quantity of extra web. WVhile the lower loop is taking up thirteen inches of web fed in by the calender-rolls the upper loop is paying off thirteen inches of web to the delivery mechanism, so that no web is drawn over roller M during the passage of the impression-cylinder over the type on the bed. The moment the carrier passes the end of the bed and .while it is momentarily stopped or almost stopped while the wrist-pins and pitmen are passing the dead-centers the looping-frame drops and the lower loop gives 0E thirteen inches of web, while the calenders pay in thirteen inches, making twenty-six inches of web which will pass over roller M, while simultaneously the upper roller Z forms a loop requiring thirteen inches of web, and at the same time an additional thirteen inches of web is drawn out by the delivery mechanism while the cylinder is off the type. It will thus be seen that at one time while the main loop of the web is stationary one looping-roller takes up thirteen inches of web paid in and the other looping-roller gives out thirteen inches of web previously looped on it, and that when the cylinders reach the end of their stroke and are temporarily quiescent, so to speak, twenty-six inches of the web is drawn over the type-beds between rollers M and M.
In other words, the simultaneous taking up and giving out of the web by the looping-rollers before and after it passes the type-beds enables the web to be fed in and delivered continuously and kept at an even tension and yet a portion of it be stopped during the taking of impressions thereon. In other words,
the first thirteen inches of web fed in by the.
calenders is'taken up in forming the lower loop and is then permitted to slip off during the feeding in of the thirteen additional inches of web, and thirteen plus thirteen equals twenty-six, the length of sheet, and at the same time while the thirteen inches of web first paid in is being collected by the lower loop the upper roller is paying out to the delivery mechanism the thirteen inches previously collected by it, and when the twentysiX inches of web are permitted to pass from the calenders and lower loop the delivery mechanism pays out thirteen inches of web and the formation of the upper loop takes up another thirteen inches, thus preventing any accumulation of web between the lower and upper loops and preserving an equal tension on the web, though necessarily moving it twice as rapidly between the upper and lower loops when it is moving at all, because the twenty-six inches of web between the loops must pass a given point in the same time that thirteen inches of web is paid in or out of the press by continuous feed and delivery.
It will benoticed that the inking-form rollers G G impinge against rollers I i, respectively, at the opposite limits of the stroke of the carriers, and owing to their loose mounting on the carriers they ride up and partly over and on the upper peripheries of said inking-rollers, increasing the time of contact therewith.
In order to raise rollers G G into proper position for inking the type,I prefer to mount small carrying-wheels G G on the gudgeons of the rollers, and at each end of the typebed I attach to the frame short guides or tracks G G, up which wheels G3 will run as the carriers are reciprocated toward the typebed and thus lift form-rollers G G sufficiently to cause them to correctly strike and distribute the ink to the type on the beds. It
will be seen that the type are inked previous to each impression and that the paper is drawn from the type immediately after impression,
unprinted surface of the paper is presented to the guide-rollers m, m, and f between the taking of the'first and final impressions, and as there is no combing or drawing of the web while impressions are being taken the resultant Work will be clean and clear cut. I As the same amount of paper is moved forward from the lower to and over the upper type-bed at each reciprocation of the impression-cylin ders, all that is necessary to make a perfect register is to adjust the position of the rollers M" m without requiring any adjustment of the paper-feeding or deli-very rolls or the impression-cylinders.
The amount or length of paper fed into the press could be varied by making the drivinggeai's'for the shafts J, and calender-rolls, and the actuating cams for the looping-frame in interchangeable set-s, calculated for dilferent lengths of sheets in accordance with the principles before mentioned relating to the relative movements of the parts.
The ink-distributing rolls I propose to drive by belting or gearing from either of the shafts B or J, and I also propose to drive the guiderollers, especially M m, by belting or otherwise at such speed that their peripheries will travel equally with the feed and delivery of the web or slightly faster, so as to comb or coax the web from the lower press to the upper.
