Nov. 26, 1935. E. C. HARTLEY PRINTING MACHINE Patented Nov. 26, 1935 2,022,198 PRINTING MACHINE Emmett C. Hartley, Cleveland, Ohio, assignor to v Addressograph Company, Wilmington, Del., a corporation of Delaware Application November 16, 1933, Serial No. 698,257

s claims.. (o1. 164-49) This application is a continuation in part of my co-pending application, Serial No. 404,123, filed November 1, 1929, issued as Patent No. 1,955,806, April 24 1934. .Y

This invention relates to machines for printing and addressing sheets forming bills, statements, notices and the like of the kind used by public service, insurance and similar companies. These sheets are usually long and narrow and comprise body portions and one o-r more stubs separated from each other and from the body` portions on scored lines. One of the objects of my invention is to sever such sheets from a continuous web so that the severed sheets may be successively passed through a machine to have printing or other operations performed thereon. These sheets usually have certain constant information printed on the back thereof and other constant information printed on the face thereof and variable information, such as the names and addresses of customers or clients, is also printed on the face of the sheets. Machines of this kind are shown in my co-pending applications, Serial No. 404,123, filed November 1, 1929, issued as Patent No. 1,955,806, April 24, 1934 of which this application is a continuation in part, and Serial No. 459,599, filed June 6, 1930.

Sheets of the kind referred to above are usually of a greater length than width. I, therefore, provide a wide web of a width equal to the desired length of the sheets so that the sheets may be successively severed from the web at spaced intervals on the web equal to the desired width of the sheets. A far greater number of sheets may be severed from the web in this manner than when the sheets are Ysevered from a web of a width equal to the desired width of the sheets and therefore by providing a widey web, as described, frequent replacement of the web is avoided. Therefore, another object of my invention is to sever sheets from a wide web at intervals spaced equally to the desired width of the sheets.

Still another object is to sever the sheets from the web without tearing, creasing or otherwise mutilating the web and an ancillary object is to sever the sheets from the web by cooperating cutter members coacting with a shear action.

A further object is to so mount the cutter members that they will co-act to be self-sharpening, that is to say, so that relative movement of the cutter members will effect sharpening of the shearing edges. Y

A still further object is to yieldingly support at least one of the cutter members to avoid the likelihood of damage tothe cutter members in event an obstruction is placed between the cutn ting edges of the'members'.

It is sometimes desirable toprovide' a web of A a width greater than the desired width of the 5 sheets as, for example, a web of twice the width of the sheets may be provided and this web may be ldividedl medially to provide two sheets of equal width, and a still further object of rmy invention is to sever the sheets from a divided. web 10 in such a manner that one 'sheet will be freed from the web prior to the other so that the sheets may be successively fed to a printing position or the like. in the machine with an interval therebetween to thereby facilitate printing or like 15 operations thereon. l

Other and further objects will be apparent from the following description wherein reference is made to the accompanying drawing illustrating a selected embodiment "of the invention and in 20 which Fig. 1 is a fragmentary plan view of a machine including my novel sheet severing device;

My invention may be used advantageously in connection with machines of the kind disclosed 40 in my previously referred to co-pending applications to which reference may be made for a detailed description of the machines. The illustrated machine which is of the kind shown in `my referred to co-pending applications includes 45 a drive shaft 'l having a bevel gear 8 fast thereon and meshed with a bevel gear 9 fast on the shaft I0 journaled in the frame VF of the machine and extended transversely across the frame below the web W which is passed longitudinally through 50 the frame. The web may be directed through a printing couple C so that impressions may be made thereon at spaced intervals or it may be -directly passed-to Va ledge l l and then below a looper roller I2 rotatably mounted on a rocker 5.5-

I3 suitably supported in the frame F and adapted to be reciprocated to alternately form and release a loop in the web W. From the looper roller I2 the web is directed between a pair of cooperating feed rollers I4 and I5, journaled in the frame F, and thence through the slot I6 defined between the horizontal ledge I1 and the plate I8 disposed thereabove. The plate I8 is carried by a bar I9 extending transversely of and secured to the frame F above the web W. Sheets S are severed from the web at spaced intervals therealong by my novel severing device, which will be described more fully hereinafter, and the. severed sheets are deposited in the sheet guideway G having feed tapes T therein which carry the sheets S to a printing or other operative position in the machine. The machine as thus far described is merely exemplary of the kind with which my in- Vention may be used for the invention is not limited to use with the details of construction thus far described.

A pocket 20 is provided in the ledge I1 below the top surface thereof and this pocket extends y into the ledge at an acute angle. A stationary knife or cutter member 2I is mounted in this pocket and has a cutting edge 22 at the uppermost end thereof and the forwardmost surface of this knife is relieved ina substantially vertical plane away from the cutting edge. A vertically reciprocal knife 23 is mounted to cooperate with the knife 2|. The cutting edge E of this knife is inclined upwardly fromv the outer ends thereof and in the form of the invention shown in Fig. 6 the apex 25 is located medially of the ends while in the form of the invention shown in Fig. 3 lthe apex 25 is located at one side of the medial part of the longitudinal extent of the knife 23.

The knife 23 is mounted in a supporting frame 24 having depending arms 24' at opposite ends thereof. Links 26 are pivotally connected to the lower ends of the arms 251 and to the outer ends of arms 21 of the bell cranks 23 pivotally mounted at 29 on the frame F. Rollers 33 are rotatably mounted at the outer ends of the arms 3l of the bell cranks 28 and are held against peripheral cams 32 fast on the shaft IB by springs 33. Springs 34 have corresponding ends thereof connected to spring anchors 35 on the bar I9 and spring anchors 3S on the frame 24, and these springs 34 act on the frame 24 to hold the knife 23 in engagement with the forward end of the knife 2I as illustrated in Figs. 2, 4 and 5.

The feed rollers I4 and I5 are driven from the shaft I0 and may therefore be operated in timed relation with the movable knife 23 which is operated by the cams 3?. on the shaft I0. Therefore, when the feed rollers I4 andv I5 have rotated to feed a predetermined length of the web W past the cutting edge 22 of the stationary knife 2i, the rises on the cams 32 engage the rollers 35 on the arms 3l and pivot the arms 21 of the bell cranks 23 downwardly to thereby move the frame 24 downwardly from the positionshown in Fig. 4 into the position shown in Fig. 5. At the time the frame 24 starts to move downwardly and when the knife 23 engages the web W rotation of the feed rollers I4 and I5 is interrupted so that the feeding movement of the web past the knife edge 22 is interrupted and the feed rollers are rmly held against rotation toclamp the web. At this same time the frame V I3 moves downwardly so that the roller I2 acts to Yform a loop in the web W as illustrated in Fig. 2.

The cutting edge 22 is straight but the cutting edge E is inclined as has been described and therefore as the frame 24 and consequently the knife 23 move downwardly the outer ends of the cutting edge E first move into cooperating relation'with the cutting edge 22 and as the knife 23 continues to move downwardly the cutting edge E cooperates with the edge 22 to sever the web progressively inwardly from the side edges thereof and such severance of the web progresses inwardly to the apex in the cutting edge E. By reason of the progressive cutting inwardly from the edges, the cutting action is like that of a shear which serves to effectively sever the web without crumpling or tearing it.

Subsequent to the time the apex 25 finally severs the sheet, the rollers 30 on the arms 3| move onto the drops of the cams 32 and therefore the springs 33 may act on the arms 3| to effect raising of the arms 21. The springs 34 are stretched when the frame 24 moves downwardly and when the arms 21 start to move upwardly these springs serve to return the frame 24 to its upper position illustrated in Fig. 4.

The forward surface of the knife 2I is disposed in a substantially vertical plane and the rear surface of the knife 23 also lies in a substantially vertical plane and after the cutting edge E moves past the cutting edge 22, the sliding of these vflat surfaces on each other effects constant sharpening of the knife edges whereby the cutting edges are maintained sharp and this insures a good cutting action.

When the apex is located as shown in Fig. 6 the nal severance of the sheet from the web occurs medially in the transverse extent of the web, and as soon as the sheet is severed from the web the rollers 31 in the frame 24 move into clamping relation with the roller 33 mounted in the frame F immediately forward of the ledge I6 and the rollers 31 remain in clamping relation with the roller 38 for a sufficient time to move vthe severed sheet out onto the feed tapes T in the sheet guideway G. Thus the rollers 30 do not move onto the drops of the cams 32 until after an elapse of a sufcient time to permit the roller 38 which is driven from the shaft ID to dispose the severed sheet on the tapes T.

A rod 39 is mounted in the frame F and extends transversely thereacross. Arms. such as the arm 43, may be mounted thereon at spaced intervals and these arms carry discs 4I. The discs 4I bear against that part of the web passing over the roller I 5 from the roller I2 and the peripheries of some of these discs are notched to score the web to thereby divide a sheet severed from the web into a main body portion and one or more stubs.

YThel disc 4I illustrated in Fig. 2 is mounted medially of the width of the web and the periphery thereof is sharpened to provide a cutting edge and this cutting edge cooperates with the roller i5 to divide the web medially. If, however, the disc is located'in a position'other than medially of the web, it is obvious that it will divide the web longitudinally into unequal sections.

In the present instance wherein the sharpened disc 4I is located medially of the web to divide it longitudinally into equal sections, the apex 25 in the cutting edge E, as illustrated in Fig. 3, is located to the right of the medial part of the web for in the arrangement illustrated the feed tapes T are driven to move through the guideway G to the left in the machine, as viewed in Fig. 3. Therefore, when the apex in the cutting edge 24 is located as shown in Fig. 3 the sheet to be cut from the left hand half of the' web is completely severed from the web prior Yto the time the sheet Vaoeaioe 'is'severed'from the right hand half of the web.

-control of the sheets to permit printing or other operations to be performed thereon. It will be understood from the foregoing that when the web is divided longitudinally the apex inthe cutting edge of the movable knife will be so located that the sheet first severed from the web will be that which will be picked up and carried away by the conveyor mechanism, which in the present instance is the feed tapes T, prior to the time the sheet last severed is picked up and this insures an interval betweensheets Yso severed from the web.

The severing device or cutting mechanism of this invention operates so that the cutting mem- ,bers coactV wth a shear action and consequently the web is cleanly severed without tearing, crumpling or the like. Moreover, the reciprocation of the knives of the severing device relative to each other effects self-sharpening of the edges Vand maintains a clean cut edge and this avoids replacement of the knives from time to time. Furthermore, the severing device may be operated in timed relation with the feeding means for ,advancing the web and therefore sheets of a predetermined and uniform width may be severed from the web. Since the knives of the severing device coact with a shear action it is possible to sever a web of relatively. widewidth and therefore the web may be furnished in the Width desired for the length of the sheet which is particularly advantageous in the case of utility bills and the like.
