Application filed November 27, 1908, Serial No. 464,771. Renewed August 26, 1913. Serial No. 786,799.

To all who/m it may concern:

Be it known that l, l `niconarcn M'. Tinten, a citizen of the United States. and resident of Rosebank. in the county oiI Richmond and State of New York. have invented certain new and useful lmprovements in lVeb- Printing Presses, of which the following,T is a specification.

The invention relates to improvements in web-printing machines in which the web is printed upon both surfaces, laterally sev ered. and delivered either as fiat sheets or to a folder as may be desired, the invention being particularly adapted for. multi-color work, such as the printing of labels and magazine-covers. and for similar products requiring variable sizes of sheets. The object of the invention is to provide means for printing and cutting such variable oi' sheets upon the same mechanism with comparatively slight change or adjustment of the parts thereof; and the invention further consists. in the construction, arrangement and combination ot' the several parts hereinafter shown. described and claimed.

In describing the invention in detail, retercnce is had to the accompanying' drawings, forming' a part ot this specification, and wherein like characters of reference are used to designate corresponding parts throughout the several views. and in which;

` tixedly secured the front and rear main' 'Figure 1 is a sectional side elevation of the improved printing' and cutting machine eirliodvinfir my invention; and Fig., :2 is a ground plan .of theI same.

ln the drawings, numeral 1 indicates the base ot the machine, upon which are frames or standards, respectivelyY numbered 2 and 3, and upon the base are also mounted the movable front and rear frames, indicated respectivelyY by i and 5, the latter frames being provided with rollers (i. adapt ed to engage tracks or grooves 7 in the base tor maintaining alinement with the main frames. A third set 'ot' front and rear trames S and 9. respectively, slide upon the movable 'frames i and 5i, and are arranged for alined longitudinal adjustment therewith bypsuital'ile `adjusting screws 1G, rhe several setsof iframes are provided with appropriate cross-braces, and Within the frames are rotatably mounted the impression-cylinders 11, 13. 15 and 17, and the correspondingr form- cyliinlerg 12, 14, 16 and 18, the latter cylinders carrying detachable forms or printing-plates adapted to be changed to suit the required lengths of printed surfaces or sheets and which coact with suitable inkingr mechanism, indicated by the distributing-cylinders 19 and the form rollers 20. The main frames 2 and 3 are further provided with bearings in which is mounted a shaft 21, loosely supporting a. frame, comprising the suitably-braced side arms Q2, having bearings corresponding with oppositely-disposed boxes on the main trames in which are coactively mounted for rotation the cutting-cylinders 23 and 24, the Feed-rollers 25 and Q6. and the perforatorshafts 27 and QS. The side arms are provided at their outer ends with pivotallymounted adjustable connectionslinks Q9, the lower ends of which engage the eccentric ends of a cross-shaft 30, which lat-ter is mounted to make a partial revolution inthe main frames and is provided at one end with a hand-lever 31, by which the mechanisin carried by the side arms may be raised to permit the threading of the web. Also for the introduction of the web through the press the lower impression-cylinder of each printing-couple is journaled in vertically movable boxes, supported upon slidable bars 3Q, shown in dotted lines, and preferably mounted in perforat-ions or cores formed cen r: lly in the several frames. The bars enga eccentric portions formed on the cross-shafts 33, all of which shafts are adapted for partial revolution in the frames for raising and lowering, said lower cylinders. the actuating mechanism for the shafts beingroic common construction, not shown.

-Mounted in the frames of the press for coaction with the form-cylinders 14, 1G and 1S, is a web-compensating;` device or frame comprising the two rock-shafts Si, upon which are fixedlv mounted the doublea1'mcd levers 35 and 3 6, having; bearings upon their upper ends in which are journaled the rollers 37 for supporting and guiding the web. a belt-rolle:l 3S being similarly mounted in the ends of the lower arms ot levers 3G.

P, Connecting these latter arms with pivotal connection-straps 39, Iare a pair of similarly Adjacent the fornrcylinder 12 is com-,

pensating-frame composed of a pair of side bars 46, having cross-braces 47, vadapted for pivotal support upon the oscillatory arms 48 and 49, the arms being fiXedly supported upon the rock-shafts 50, journaled in' the main frames of the press. In the compensating-frame are journaled the rollers 51, adapted to support and guide the web in substantially horizontal printing relation with the adjacent printing-couple, which manner of web support corresponds with that of rollers 37 in relation to their printingscouples. The arms 48 and 36 are connected together by the links 52 and the crossconneetion levers 5B, the latter being supported upon extensions 54 of the frames and pivotally arranged therewith and with the links and arms to permit of the latters oscillation in opposite directions. Connectionlinks 55, provided at one end with bifurcated jaws 56, serve to detachably connect arms 35 and 40. These links are further provided with suitable longitudinally-adjlisting means, not shown, for the accommodation of the adjustment of the movable frames 4 and 5.

Journaled in the main frames and adapted for frictional engagement with'belts 44, is a feeding-cylinder 57, having a diameter and speed similar to that of the several form and impression cylinders. Below the feeding-cylinder and coacting therewith is .a compensating-cylinder 58, provided with a detachablek peripheral contact-surface 59, which. engages the web during its travel through the press and exerts a pressure thereon to urge the belts in contact with the feeding-cylinder 57, and with which it is drivenin unison and at a constant speed of rotation by suitably disposed gearing ar-Y ranged exteriorly of the rear main frame 3. In the` rear mainy frame is also journaled a main driving-shaft 60, provided with an ex terioi` bearing 6l, and ha ving a belt-pulley 62 and a piniongear 68, thelatter, shown as a dotted circle url" ig. 1,-intermeshes with the intermediate gear 64, from o'pposite sides of which are driven in unison the several printing-cylinders and` their respective inlting mechanism, the gearing -for form- cylinders 12 and 14 being arranged in a straight line inders 14, 16 and 18, are secured bevel-gears 67, which engage correspondin bevel-gears 68 and 69, secured to way-shaft 0, the latterl `being rotatably mounted in bearings 71,

fixedly secured to the rear movable frames. This shaft is longitudinally fixed, relativel with the movable frames 4 and 5, by the co lar 72 and the hub of theixedly-seoured bevel-gear 68, the bevelgears 69 being adjustably fixed upon the shaft to permit the adjustment of the movable frames. posed below the bevel-gear on the shaft' of form-cylinder 14 and engaging therewith, is a bevel-gear 7 3, secured to the vertical shaft 74, which latter is rotatably mounted in suitable bearings securedto the rear main frame and is provided at its lower end with a bevel-gear 75, which engages a correspondmg bevel-gear 7 6, secured to the shaft of the feeding-cylinder 57.and shown by dotted circles in Fig.- 1. Engaging bevel-gean 76, is 'a corres onding gear 77, secured to the wayshaft 8, the latter being rotatably mounted in bearings 79, secured to the rear main frame of the press. Upon the opposite end` of the way-shaft is secured a bevel-gearf80,

engaging the `corresponding bevel-gear 81, the latter being fixed to the intermediate gear 82, which is loosely mounted upon 'a short stub-shaft 83, secured to the rear main frame of the press. Also mounted upon the stub-shaft 83 is an adjustable arm 84, carrying an intermediate gear 85, which intermeshes with the intermediate 82 and also engages the gear 86, secured to the lower cutting-cylinder 24, for constantly driving the latter at a uniform rate of speed a number of .revolutions corresponding to that of the several printing-cylinders, Vin order that a sheet may be cut at each revolution-of the latter.

-Verticallyndjustable bearings are provided for the` cutting-cylinders to permit of the suitable engagement of their cutting mem- Disbers, which members are radiallycadjustable in their respective cylinders for cutting variable lengths of sheets,vv it being evident that a radial change in the'cutting members 1 'will producel a proportionalV change in the length of the sheet cut'at each revolutonof the cutting-cylinders. 'Removably secured upon the rear ends of the shafts of said c'uttingoylin-ders are a pair of change-'gears corresponding in radius to the radial change in the cutting members and adapted to positively drive the cylinders together, the gear for the upper cylinder being indicated by numeral 87 and more clearly shown in Fig.

2, the gear for the lower cylinder being in 130- dicated by 87, and, as herein shown, it corresponds in diameter with the iixed gear 86 and is laterally disposed therewith. f

Upon the vertical adjustment of the lower cutting-cylinder 24, the arm 81 is likewise adjusted to aiiord the necessary engagement between the intermediate gear S5 and the fixed gear 86, secured to the lower cuttingcylinder. It will be seen that the changegears are arranged in a second train. the lower gear 87a engaging the intermediate 88, rotatably mounted upon the bracket 89, the latter being adjustably supported upon the frame for the accommodation of the variable sizes of change-gears. The intermediate 88 engages gear 90 for driving the lower feed-roll 26, which gear in turn, through the intermediate 91, drives a gear on the lower perforator-shaft 28, which latter engages the corresponding gear 92, secured to the upper perforator-shaft 27. This train of gears is further extended from ..the lower perforator-sha't't by the intermediate 93, which is loosely mounted upon a stud 94, fixed in the frame. Laterally secured upon the intermediate is a bevel-gear 95, which 'engages a corresponding bevelgear 96, xed upon one end of the way-shaft 97, which latter is rotatably mounted in bearingsv98 and provided vat its opposite end with a bevel-gear 99, which engages and drives a corresponding bevel-gear 100, .lixed upon the i end of the shaft carrying the auxiliary feeding-roller 45.

The several gea rs leading from the changegears on the cutting-cylinders are so proportioned as to maintain a common peripheral speed of the cutting-cylinders 23 and 24, the lower feed-roll 26', the disks on perforator shafts 27 and 28, and the auxiliary lfeeding-roller 45. The upper feed-roll 25 is preferably driven by frictional contact with the lower positively driven roll 26. and in place of an upper roll, a series of independently-adjustable 4pulleys may be substituted and arranged to vary the amount of feeding tension onv the web. The disks upon the perforator-shafts 27 and 28 are adapted to coperate to longitudinally perforate or sever the web for certain classes .of work only. and do not form an essential feature of this invention. The intermediate gears used for driving the several cylinders and rollers are indicated in dotted circles in Fig. 1, and are arranged to run loose up n studs or shafts in the usual manner.

etween the movable't'ralnes 4 and 5 is From the feeding-roller l5 the web is led over ay registering device (adapted for usel when the web is provided with previously imposed characters), comprising a` shaft 104.-, mounted for rotative adjustment in the arms 36, and carrying a guiding-roller 105, loosely mounted for rotation thereon. Fixedly secured to the shaft at opposite ends of the roller are a pair of arms 106, in which is journaled a roller 107, adapted for oscillatory adjustment with the shaft to 'ary the length of the web between the guiding-roller 105 and the superposed roller 37, journaled in the upper ends of arms 36. From this latter roller the web passes, in a substantially horizontal plane, below the form-cylinders le, 16 and 18, and oyer the opposite roller 37, journaled in the upper ends of arms 35, to the guiding- rollers 108, 109 and 110 and thence to the registering-roll 111 and the guiding roller 112. The guidingroller 108 is loosely mounted for rotation upon the shaft 34, and the similar rollers 109, 110 and 112 are rotatively mounted in the frames. Registering-roll 111 is rota.- tively mounted in a pair ot' arms 113, which are secured to a shaft 114, the latter being mounted in the frames for the oscillatory adjustment of roll 111 to permit of varying the length of the web between rollers 110 and 112 for suitably registering with the printing-couple 11 and 12. The web passes from the guiding-roller 112 to the rollers 51, which support it in printing relation with form-cylinder 12, and from which it is led to the guiding-roller 115, and thence. between the perforator-shafts 27 and 28, feeding-rolls-25 and 26, and the cutting-cylinders 23 and 24, from which it may be delivered by suitable devices either as flat sheets or conveyed to a folding-machine.

In order to facilitate the introduction of l the web through the machine, the compensating-cylinder 58 is journaled in verticallymovable boxes, supported in like manner as described for the impression-cylinders of` the printing couples, upon slidable bars 116,\t which engage eccentric portions',.formcd on the cross-shaft 117 which latter .is mounted in the main frames and adapted to make a partial revolution by the niovenient of handlever 118 for raising and lowering said cylinder. l

ln the travel of the web through the mac-.ine its normal speed is controlled ,by the feeding-rolls 25 and 26, in conjunction with the auxiliary feeding-roller 15 and the endless belts 47, these parts being positively driven from the lower rutting-cylinder by the change-gear Si correspondingto the gear S7 on the upper cutting-cylinder, it

will follow that a change in the diameter 1 muni length of sheets. For this length of sheet the compensating-cylinder 58 ma be lowered for disengagement'with the eediug-cvlinder 57 or it may be provided with a full peripheral contact-surface 59 and retained in its upper position Ywhere it will act as an additional feeder for the web. This uniformity of web speed while printing the maximum length of sheets will produce no action upon the compensating devices, which include the several arms 35, 36, 118' and 49,

all of which will be held as shown, at one extreme of movement by the contractile spring 119, secured at one end to lever 35 and at its opposite cnd to a bracket 120, fixed upon the frame. lf, however, shorter lengths of .sheets are required, the cutting members of the cutting-cylinders are adjusted accordingly and the corresponding gears provided therefor', also, the peripheral -length of the contact-surface 59 for the compensating-c yilinfler 5S is made to Conforni with the length of the desired sheet to be cut, and the same is securely adjusted upon the cylinder, and acts in unison with the several likewise-reduced forms or plates upon the printing-cylinders, indicated thereon in solid lines. The contact-surface 59 is preferably composed ofa flexible sheet of fibrous material, of a suitable thickness to `afford a clearance for the independent return movement of the web over the uncovered peripheral portion of thevcylinder.

The several sets of printing-cylinders are.

adjusted in relation to their forms to jointly make their impressionsupon the web in the same period of time, and itwillbeevident that during the periodin which the impressions 'are taken the impressed portion of the web must travel at a.4 speed corresponding withthat of the printing-surfaces, and as the peripheral length of 4these surfaces is-reduced in accordance with the required reduction in the length of sheet to be cut, the printing periods of time will likewise be reduced, and the intervals between the impressions will be correspondingly increased.

For sheets of reduced length, the consequent normal reduced speed of the web must be accelerated at the printing-cylinders during the period of impression, and for this purpose the arms 35, 36, 48 and 49 are rcciprocated bythe action of the feeding-cylthe conipcnsating-cylinder being clear, the

arms 35, 36, 48 and 49 are retained in their backward extreme of movement, and the" web is free to travel at its normal relativelyreduced speed. By the continued rotation of the several cylinders the peripheral contactsurface on cylinder 58 engages and accelerates the portion of the web carried between the rollers 38 and '12 to an amount equaling its own peripheral'speed. This acceleration is induced by the tension between the two coacting cylinders 57 and 58, causing a gradually increasing tension, due to the increase of speed, upon this portion of the web and its Contactin belts which produces a relatively slow -torward movement of the several connected arms in opposition to vthe spring 119,' the forward movement continuing during the action ofthe peripheral contact-surfaces and causing a correspondingly accelerated speed on the portion of the web engaged by the printing-cylinders which` conforms with the printing speed.

As the several printing-couples make their impressions at one time, and the couples includiiig form- cylinders 11, 16 and 18 make their impressions successively'upon the same printing-surface, it is to be noted that the latter couples are centrally spaced apart to conformV with the required length of sheet to be cut, the necessary spacing therefor being effected by the longitudinal adjustment of the movable frames. For frames 4 and 5 this adjustment is accomplished by the screw-threaded connections 121, which are pivotally mounted at one end to the movable frames and are provided at their opposite ends with bifurcated jaws 122, adapted for detachable connection to pins 123, fixed upon the main frames, and fromwliich the movable frames may thereby be readily disconnected and sufficiently separated to a'fi'ord access to the center of the machine. Vith the adjustment of these frames a corresponding variation is made in the length of the connection-links 55.

Asshown, the'forin- cylinders 14, 16 and 18 are adapted to print in separate cliaiacters or colors on one side of the web, and for perfecting or printing the opposite side thereof, form-cylinder 12 is employed, per-l fect register of the latter printing-surface being effected by the registering-roll 111. lt will thus be seen that the described mechj anisin is adapted for a wide range of work both as regards the length of sheet and the colors or characters printed.

I am aware that heretofore web-printing Amachines have been designed having conmovement of the web causes an excessive Strain thereon, which is augmented by the variation in the rotative action of its supporting-rollers, and produces an irregularity which .impairs the register for high-class work.

The present invention is distinguished from such machines in prfcividing means for maintaining a constant travel of the web at the same rate ot speed with respect'to its supporting-rollers, and for accelerating the portion` of the web engaged by the printingcylinders without affecting the rotative actior of the supporti11g-rollers; the acceleration being soigradual as to be practically unnoticeable as regards the momentum ot' the web.

It is to be4 understood that the arrangement of the several parts of the machine may be modified to include a' greater or less number of printing-couples, so disposed as to make a greater or less number of' impressions on one or both sides oi the web. lt is also evident that the invention is susceptible oi. various changes as regards its form, proportions and detail construction without de- .i parting` from the essential spirit and scope or sacrificing'any of the advantages thereof.
