SPECIFICATION forming part Of Letters Patent NO. 607,131, dated July 12, 1898. Application filed September 30, 1896- Serial No, 607,{i29. (No model.)

To LLZZ whom it may concern.-

Be it known that I, ALBERT H. RAY, of Ashland, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Printing-Presses, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention has for its object the provision of a compact machine of the rotary class for printing or otherwise operating upon a web of cardboard or like material, and preferably comprising mechanism for thereafter severing the printed strip into portions of predetermined length. 7

The various features of my'invention, will be fully illustrated and described in the drawings and specification and set forth in the claims.

In the accompanying drawings, Figure lis a view in rear elevation of my invention, Fig. 1 being a detail of construction, to which reference will be had later. Fig. 2 is a side elevation looking from right to left on Fig. 1. Fig. 3 is a side elevation looking from left to right on Fig. 1; and Fig. 4 is a sectionalview on the line a: 00, Fig. 1, looking from right to left.

In the preferred embodiment of my invention, illustratedin the drawings and to which reference is had herein, in a frame A of suitable construction and contour is mounted between the uprights (L a an impression-cylinder B, fast upon a shaft a extended beyond the frame to receive the studded drivingsheave B, the cylinder and sheave being of the same radius.

Parallel with the shaft a is mounted the main drivingshaft 0, provided with suitable driving means, herein shown as a crank-handle c and having near one end outside and adjacent the upright a a driving arm orsector 0, arranged upon continuous rotation of the shaft G to be brought into position to successively engage the studs b on the drivingsheave B, immediately adjacent their region of union with the sheave, to impart at each of such engagements an impetus to the sheave and to maintain, respectively, the successive movements then initiated during and by subsequent frictional engagements with the said sheave, preferably through a friction-block c fastened to the sector by a screw-plate 0 Fast on the shaft O, between the uprights and preferably, as shown, integral with a sleeve'D, is a sector or radial projection cl, recessed to receive a chase d, held therein in adjusted position by means of the set-screw (Z and in turn adapted to receive a form of type, the individual rows d of which are respectively secured in adjusted position by means of set-screws (F in such manner as to insure upon operation of the machine their contact with the strip E (see Fig. 4:) as it is fed over the impression-cylinder by suitable controlling means comprising, in the instance illustrated, teeth 12 with which the periphery of the said cylinder is provided and which are adapted toj'enter perforations previously formed ,in the web to insure proper positioning of the web during the operation of printing and severance.

As one convenient, form of means to ink the form an inking-cylinder F is provided, from which the ink is taken by an inking-roller F,

so positioned as to come into peripheral con-' tact with the type substantially at the uppermost position of their arc of rotation.

This ink-roll is driven bya disk a, mounted on the driving-shaft O, and in turn drives the inking-cylinder, which is reciprocated longitudinally on its spindle Q to insure proper distribution of the ink by means of a cam f, engaged by a notched finger a fast upon an arm a of the frame. The spindle a which carries the ink-cylinder F, is adjustable in a slot a in the said arm a, being secured in adjusted position by the nut a, and the spindle c0 which carries the ink-roll F, is likewise adjustable in the slot a, being secured in position by the nut a The shaft (6 is normally held stationary with one of the studs 1) on the driving-sheave B in position to be engaged by the drivingsurface of the sector 0, the holding means consisting, in the instance illustrated, of a spring-actuated stop H, (best seen in Fig. l,) mounted in the upright a and normally held by the spring h with its inner end 72, against the edge of the iinpression-cylinder, which latter is pierced with a series of holesb", Figs. 2 and 1, adapted to receive the end of the stop, and so positioned that when the stop enters anyone of the holes the driving-sheave B will be heldwith one of its studs, as above described, in position to be engaged by the driving-surface of the arm or sector 0. To disengage this stop in order to permit feed of the web, I provide the driving-shaft with a collar 0 having a cam-surface adapted to engage one end of a lever K, pivoted at It on the frame, the other end of the lever being in position to engage a shoulder 7L2 on the stop II and to force it outward when actuated by the cam so to do against the action of the spring h to withdraw the inner end of the stop from the impression-cylinder. This cam is so positioned as to disengage the stop and free the impressioireylinder just as the typecarrying sector is approaching its printing position, and immediately after the imprint has been made the cam-surface 0 passes the lever K the stop is released and comes into contact with the edge of the impressiorrcylinder, automatically entering the next hole as it is brought around.

Having thus fully described the printing means, which, it will be understood, has been selected for illustration as constituting a typical instance of a rotary couple to which my novel actuating means may be applied with advantage in this class of machinery, I will now describe the apparatus with which the machine illustrated has been shown as provided for severing the web after it has received the imprint from the type and which constitutes one form of mechanism which may I be employed.

At the rear of the impression-cylinder is mounted a shearing device, the lower member of which consists of a knife or preferably two knives M M, held slightly separated by setscrews m in a frame m, which in turn is adj ustably mounted on a bed e on the frame A by means of set-screws m This frame m is provided at the rear of the upright a with an upwardly-extending lug m which carries, by lneans of a pivot m the lever N, and on the arm n of the latter is carried the other member or knife M of the shears, it being removable and arranged to enter the slot 10 between the lower knives M M and exercise a shearing action in connection with the latter on the web E as it is fed across the knives M M from the impression-cylinder. Normally the knife is held in its uppermost inoperat-ive posit-ion by the force of a spring P, attached at its lower end to the upright a and atits other end to the arm 'n' of the lever N and exerting a tendency to draw the latter downward.

As one means for depressing the knife M and operating the shears against the action of the spring I have illustrated a lever R, fulcrumed at its end 9' upon a horizontal post a carried by an arm (1, of the upright a and having its free end connected to the arm n by a link R. The middle portion of this lever B is carried past the extended end 0 of the driving-shaft and is adapted to enter a slot in and be engaged and operated by a cam o carried by the said driving-shaft. The operatingsurface 0 of this cam is brought into contact with the lever B after the type has passed the printing position, and while the stop II holds the impression-cylinder l3 and the web E thereon immovable for severance by the shears. After the surface c is carried beyond its uppermost or operative position the spring 1 draws the end 91 of the lever down again, raises the knife M, and the web E is again free to be fed forward during the operation of prin tin As a means for guiding the said web into position for engagement of the perforations by the teeth I) and also to guide it from the impression-cylinder to the shears I have provided in this instance a frame-like device, herein shown as formed in two parts, separated to allow passage of the cylinder-teeth between them. These parts are exactly similar in every respect, but are oppositely faced, one for each side of the strip to be operated upon,and each consists of a bodypiece S, mounted intermediate the l11l1)l0SSlO11-Gylil1(101 B and shears M M on a transverse rod T, the ends of which are supported in suitable bearings 15 L in or attached to the frame A, while set-screws '1' i permit the rod and body-piece to be fixed in adjusted position relative to each other and to the bearings if t.

From the respective body-pieces S S are extended forward-curved arms 3 s, at the ends of which are transverse fingers s s, between which the web E passes to the feedingteeth b and after the printing operation the web passes beyond the impression-cylindcr through slots 5 5 in the relatively broad bodypieces S S, the latter serving a function similar to that of the fingers s s in guiding the strip onto the lower shears M M.

IVit-h an impression-cylinder very large in periphery relatively to the type area it is possible to secure a large number of impressions upon the web during a single revolution of the impression-eylinder, with consequent advantages of smooth operation and freedom from wear; but to do this it is necessary to rotate the members of the printing-couple out of phaset'. 8., having different periods of complete rotation-and so far as I am aware I am the,first to provide actuating means for the cylinder of sufficiently accurate operation to insure the degree of nicety requisite in producing a series of closely-spaced impressions individually small in area upon a continuous web, where the members of the printing-couple differ so eonsiderablyin area.

The feeding mechanism in the machine illustrated is so adjusted that the imprints are made on the web E between the perforations, and by providing a broad knife M, co operating with two knives M M, I am enabled to out each time from the web a narrow portion, in the middle of which is one of the perforations, whieh'latter would be unsightly if left upon the leaves after severance.

Having thus fully described my invention, I do not limit myself to the exact construction shown, for it is obvious that many portions of the structure may be varied considerably without departing from the spirit of my invention, the division of parts by the frame-uprights, &c., in the preferred embodiment illustrated being to a considerable extent merely arbitrary or for convenience as, forexample,in the separation of the sheave from the impression member and the radial projection or rotary printing member from the actuating-arm or interrupted driving-surface.

I have used the term sheave not, of course, to convey the idea of a grooved pulley, but merely asaconvenient term by which to designate the structure provided with a stud bearing friction-surface, whether a separate member or not, which cooperates with the interrupted driving-surface.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A machine for operating upon a continuous web of flexible material, comprising websevering mechanism; a rotary printing member or the like; a rotary impression member of large diameter, relatively to the effective area of the printing member, and capable of operation out of phase therewith; and means upon said impression-cylinder to engage the work and automatically position the same for alarge number of printing and cutting operations during a single rotation of said impression member, substantially as described.
