Specification of Letters Patent.

Patented Manse, 1918.

continuation in part of application Serial No. 714,432, filed August 10, 1912. 1 This application filed August 11, 1913. Serial No. 784,078.

To all whom it may concern:

Be it known that I, WILLIAM F. Mnnnns- FORD, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Perforating Mechanism, of which the following is a full, clear, and exact specification.

This invention relates to perforating and cutting mechanism, and has particular reference to the-manufacture of cutout wall paper, such as borders, friezes, crowns, binders, rosettes, corners, etc., which are applied to walls in conjunction with the body finish for the purpose of increased decoration. These cutouts the present. time for decorating purposes, and as heretofore made and sold to the trade, have been printed, dried, out and then wound in rolls with a filling paper ready for use. When used by the paper hanger the filling paper is thrown away.

The object of the present invention is to provide a Web perforating and cutting mechanism especially intended for use in connection with a multi-color web printing machine, the perforating and cutting mechanism of this invention being preferably arranged so as to perforate and cut the web in advance of printing.

are largely used at.

A particular feature of this invention rev sides in the specific construction and arrangement of perforating and cutting mechanism which is applicable for general use, wherein it is capable of adjustment for different patterns, and mounted so that it can be easily thrown out of operation without disarrangement when not desired for use and without interfering with the ordinary feed of the web. As shown herein, the perforating mechanism comprises an attachment adapted to the standard forms of multicolor printing presses.

he invention,-with reference to its details and advantages, will be more fully understood in connection with the accompanying drawings, wherein- Figure 1 is an elevation of a portion of a' multi-col-or printing machine having the perforating apparatus of this invention combined therewith;

Fig. 2 is an elevation of the perforating roller provided with a design;

.Fig. 3 is an end view;

Figs. 5 and 6 are details on an enlarged scale of one of the perforating knives;

Figs. 7 to 17 show various modifications in the form of cutters;

Figs. 18, 19 and 20 are views showing modifications of the perforating mechanism shown in Fig. 1; and

Figs. 21 to 26 illustrate various designs of cutouts which canbe made with the apparatus of this invention. 7

Referring to Fig. 1, 1 represents a. portion of the frame of a multicolor web printing machine having the printing roller 2, and color rolls 3, 3, all of which are con structed in a well understood manner so that each roll 3 prints a different color and all are driven in synchronism with the roll 2 by means of a large gear 4 meshing with driving gears on the shafts of rolls 3, and with driving gear 5. 6, 6, 6 are idler rolls over which the web 7 runs and 8, 8 are tension rolls or bars. 9 represents an auxiliary frame for the perforating mechanism which is herein shown as attached to an extension of the main frame 1, but which may be otherwise supported, if desired. 10 is a counter or platen roller provided with a resilient surface 11 between which and the perforating roller 12 the web 7 runs, and

.is at the same time fed thereby. In order to properly effect the perforation of the web, it will be seen in all forms of platen devices herein illustrated, that the web is bent around the platen, so that it is under tension and at the same time flattened and firmly held on the yielding platen surface while in contact with the perforators or knife pins.

The counter or platen roll 10 and the perforating roll 12 are provided with intermeshing' gears 13, 14, the latter meshing with gear 15 which gears with gear 5 above described, so that the perforating roller 12 and the counter roller 10 will be positively driven in exact synchronism with the printing rolls 3, and each other, so that the web is simultaneously fed and erforated exactly in synchronism with the printing design rolls 3. The perforating roller 12 is rovided with a peripheral adjustment not shown) with relation to its gear 14 and axial adjustment (not shown) for the purpose of accurately positioning the pattern on the perforating roller 12 with relation to the pattern on the printing roller or rollers 3.

The platen or counter roller 10 is provided with a shaft 16 which is carried by levers 17 journaled at one end 18 in the auxiliary frame 9 and having at the opposite end 19 a link 20 pivoted at 21 to a lever 22 journaled at 23 on the frame 9. By pressing down on lever 22 the counter roller 10 will be lifted from engagement with the perforating roller 12. To control the contact between the resilient surface 11 of counter roller 10 and the perforating roller 12, a set screw stop 24 is provided which can be adjusted up or down to support the short end of lever 22. When it is desired to remove the perforating mechanism, a hook 25 on chain 26 is engaged with a transverse bar 27 connecting the lower ends of side frames 9, thereby holding the counter platen clear of the perforating means. The platen roller 10 is preferably made wider than the web, so that it can be shifted axially on the shaft to change the cutting surface, and it is also driven by an uneven gear, so that it will not coincide with the design, thereby prolonging the life of the resilient covering.

The movable frame 28 consists of two side frames connected by a tie rod 34 and each mounted at 29 on the shaft of the gear 5,.

thus permitting the perforating roller 12 to be swung toward and from the platen roller 10 without changing the meshing of gears 5, 14, 15. The bearings of, roller 12 are thus adjustable toward and from the platen, to allow for various sizes of perforating or platen rollers. The intermediate idler gear 15 is carried on a shaft 30 which is adjust able ina slot 31 of the swinging side frame 28, so that when perforating roll 12 is changed in diameter, gear 14 will be like wise changed to correspond, and still be driven synchronously with the printing rollers 3.

Inasmuch as color printing machines are arranged so that various diameters of print ing rolls are to be used according to the pat.- terns to be printed, it is desirable in the operation of this machine that the perforating roll be of the same circumference as the printing rolls, which is provided for by first adjusting the frames 28 relatively to frame 9 by pins 32 passed through holes 33, the holes 33 being spaced in accordance with standard circumferences of perforating rolls, which latter will be made in circum ferences corresponding to the standard diameters' of printing rolls 3, or multiples thereof if a pattern is repeated. The perforating roller 12 is preferably mounted in lopen bearings so that upon lifting the counsheet metal.

being seen that the side frames 9 and 28 are curved to facilitate this operation.

Figs. 2 to 6 show the details of the perforating roll 12. It comprises a body or center of suitable material with a periphery 35 of wood or similar material into which the .knife pins 36 can be driven. These cutters 36, as shown in Figs. 5 and 6, and also in Figs. 7 to 17, are provided with knife edged heads 37 with sharpened cutting edges 38 which readily sever the fiber of the paper without tearing. It will be seen in Figs. 5, 6, 7 and 8 that the flattened blade portion 37 is of less thickness than the shank portion 36, thus providing driving and depth gaging shoulders 37*, and the designs 39, 40 are formed on the surface of roller 12 in Fig. 2 by driving into the surface the requisite number of knives to form the outline to be cut or perforated in the paper. A practical requirement of this perforating roller is that the cutting edges must all be on practically the same diameter or exactly the length when developed, of the pattern which will be printed on the wall paper, as otherwise the perforations would not register with the printing, which result is facilitated by suitable pin setting mechanism. In order to make sharp curves in the line of perforations so as to form angles, etc., the shanks 36 are preferably made round in cross-section so that they can be readily turned or angularly adjusted after having been driven into the body of the roller 12, and the sides 37 a of the flat portions 37 taper to-' ward the base so that the knife pins can be subsequently to be driven farther in without displacement, as may be necessary when the printing rolle s are resurfaced.

Cutters of other forms are shown in Figs. 9 to 15, such as may be made from fiat or Fig. 9 shows an opening 65 in the blade portion 36 serving as a driving shoulder. In the cutter shown in Figs. 11 and 12, the projecting or bent metal portions 66 serve as driving shoulders. The cutter illustrated in Fig. 13 is trapezoidal in shape, and is provided with the beveled sides 67 adjacent the cutting edge 68, the sides 67 serving as driving shoulders. Figs. 14 and 15 show cutters each provided with a plurality of shanks 64 attached to'the body portion 70. In Figs. 14 and 15 the beveled sides 67 serve as the driving shoulders. The modified form of cutter as shown in Figs. 16 and 17 comprises a main body portion 72 having an opening 73 whereby it may be held in position on the roller 12 (Fig. 1) by means of a screw or the like; the short shanks 74 project transversely to the main body portion 72, and are adapted for inserduplicate cutouts, it being seen that the bor-" ders are symmetrical so that duplicates can be made. In Fig. 22 two cutouts of diflerent outlines can be made atonce with'a small waste portion which the paperhanger can.

separate and throw away. In Fig. 23 a somewhat difi'erent form is shown wherein two borders would be made at once of the same outline with waste pieces perforated ready for separation. In Fig. 24 two borders of different outlines would be made at once by proper rows of knife pins witha continuous waste strip between. In Fig. 25 is represented two borders with a binder strip formed in between without extra expense save in the setting of the knife pins, and with minimum waste of paper. In Fig. 26 is shown a method by which independent cutout ornaments can be made on a web. In all of these figures it is to be observed that the perforated designs on the web will bear a predetermined relation to'the printed designs, which will work out in practice, because there is no opportunity for stretchin of the web between the time it is perforated and the time it is printed, it being well known that evenslight dampening of a web causes it to stretch and warp and renders it necessary that the perforating and printing devices be very closely disposed relatively to each other and that they operate as nearly simultaneously as possible. It is therefore more advantageous to perforate the web before it is printed than after, because after the web is printed, especially where a number of colors are printedfi't becomes damp and liable to stretch, and the amount of stretch varies with the particular web in many instances so that exact registering is more easily obtained by the specific arrangement of the parts herein shown. When dampened by paste, the design is readily separated along the perforations by tearing, and the paper cuts more smoothly when dry. Moreover, it will be observed that the perforating devices acton the face of the web, so that an rou hened edges will appear on the back, there y not affecting the lay of the color.

In Fig. 18 a somewhat modified arrange ment is shown for mounting the knife pins, wherein 52 represents a chain rotating o ver sprockets 5.3, one of the sprockets 53 belng geared to the printing machine as through a gear similar to 5 before described, so that the chain will rotate in, synchronism therewith. p 54 represents wooden blocks carried on the chain links in which the pins are driven by the same mechanism as before described, or any suitable modification thereof by driven platen rollers 56, 57 carrying a rubber or other yielding belt 58 which runs under a fixed table 59, the chain 52 carrying the blocks 54 running over a table or support 60, and the web being perforated as it is carried along between the belt 58 and the knife pins carried by the blocks-54, which will be geared to move at the same linear speed and also in predetermined relation to the printing devices before described.

In Fig. 20 the chain 52 and blocks 54 are replaced byv the roller 12 before described, the platen devices being otherwise unchanged.

In addition to cutouts for wall paper, shelf papers and ornamental papers of various kinds can be cheaply produced, especially wherein it is desired to associate perforations with printed or applied surface designs or ornamentations.

This application is a continuation of my application Serial No. 714,432, filed August 10, 1912, as to all matters common to the two applications.
