My invention relates to improvements in paper-cutting machines;. and it has for its object to provide means whereby strips of paper of different widths and lengths may be cut from a web or from a number of superposed webs; and it has for its further object to provide means whereby the strips or hands of paper out longitudinally from a web or webs may be cut into sections at right angles or on lines oblique to v the lateral edges of such strips or hands.

The invention has for its further object to provide means for readily adjusting the cutters or the cutter-shafts to adapt the machine to cut strips of different widths from webs fed thereto, either from a storing-drum or direct from a' paper-making machine, all as hereinafter more fully described, and as shown in the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2, a top plan view of the upper cutter-frame; Fig. 3,

' a sectional plan view on line mm m 00' of Fig.

1, and Fig. 4 a vertical longitudinal central section, of a paper-cutting machine embodying my improvements. Fig. 4 shows, by an isometric view, a web of paper partially cut into strips. Figs. 5 and 6 are detached top plan views of'the cuttenframe, showing the same in different positions. Fig. 7 is a side elevation of one-half of one of the disks or y Wheels that carry the revolving cutter blade or blades, the blade being shown in section;

and Fig. 8 shows one of the two-part gearwheels in elevation.

The several parts of the machine are mounted and arranged to operate upon a suitable frame, F, constructed of any appropriate material.

B R R" RF R are web rollers, upon one or vmore or all of which is or may be Wound a web of paper of any desired length and of such width as will conveniently pass through the machine, said rolls being mounted on the feed end of the machine and rotate in suitable bearings secured to armsf, extending rearwardry from the main frame. These rolls R R 810., are so arranged relatively to one another that the web of paper wound upon each of them will be delivered in superposed layers to a guide-roll, T, which guides the superposed webs of paper to a pair of drawing-rolls, R R. The upper roll, It, has, preferably, a portion thereof extending from its longitudinal center toward its extremities of slightly greater diameter than said extremities, as shown at r, Fig. 3, to prevent the wrinkling or puckering of the superposed webs of paper, and said portion, as well as the remaining portion of' the roll, may be covered with felt, rubber, or other suitable flexible or elastic material, if desired, in which case the lower roll, R, will have a like covering. The upper roll, B, is

' mounted in bearing'blocks that are adjustable vertically toward and from the bearings of roll R, by means of set-screws s, in the well-known manner, to adapt said roll for adjustment relatively to roll B, according to the number of superposed webs of paper passing between them.

0 and O are disk-cutters or knives mounted upon shafts 0 c, the relative arrangement of said cutters being such as to produce a shearcut when operating together on the paper webs, one from above and one from below the superposed webs, and the shaft 0, that carries the upper cutter, O, is adjustable vertically toward or fro m the lower cutter-shaft,e, by means of sliding bearings and setserews s, as shown in Figs. 1, 3, and 4, the same as the upper drawing-roll, It, to adapt said cutters to cut varying numbers of superposed webs ofpaper. The cutters G O are adjustable longitudinally of their shafts by means of set-screws pass ing through their hubs, as shown in Fig. 3.

In practice I prefer to graduate one or both shafts to inches and any desired fractious thereof, so that the cutters may be set to cut any desired width of strip within the limits of the machine from a full width (thelateral rough edges being trimmed off) to a strip or band an inch or more in width, or to cut strips of different widths, as required or desired.

From the cutters (land 0 the trimmed coir tinuous web or superposed webs, or the continuous strips or bands, or superposed layers of such, pass between guide-rolls r 1", and thence to a guide-bar, T Figs. 4, 7, 8, and 9, secured to the main frame F at opposite ends and lying within a rabbct of an adjust-able cutteri'raine, T; or one or more of said webs or strips maybe carried upward as they issue from between the guide-rolls 1' 1 to a cutter above, as presently explained. The bearings of the upper roll, 1- are also adjustable vertically by means of screws 8', so as to admit of the passage of a greater or less number of webs or strips of paper, as will be readily understood. The web or webs or strips of paper, as they pass from the guide-rolls i 1' over the guidebar or feed-table T are cut transversely by revolving cutters mounted in an adjustable cutter-frame, T, which I will now describe.

The cutter-frame T is of rectangular form, and is pivoted at one corner on a screw, t, on which it is adapted to swing, and may be adjusted to adjust the cutter-blades mounted thereon to any desired angle within certain limits relatively to the webs or strips of paper fed thereto to cause the cutters to cut a straight or oblique out. Any suitable means may be employed to lock the frame into position when adjusted.

In suitable hearings in the side bars, t t, is mounted a cutter-shaft, S, that carries at each end within the frame a spur-wheel, O and 0, respectively, and a suitable number of disks, D, upon which are secured one or more euttor-blades, B, (one only being shown in the drawings,) the number of such cutter-blades depending on the length of sheets to be cut from the web or strips. The cutter-blade is so arranged relatively to theinner edge of the rear transverse bar, t, of the frame T that the said edge of the bar serves as the stationary cutter, between which and the revolving eutter 13 the paper is cut. In suitable bearings in said frame T and in rear of the cutter-shaft S ismounted a shaft, Q, from which the cutter-shaft is driven, as hereinafter described.

'The said shaft Q carries at its outer end, outside of the frame T, a belt-pulley, q, and, according to the adjustment of the table T, a spur-wheel, 0 or 0. Both these spur-wheels are constructed in two sections, Fig. 14, so that either one or the other may bereadily applied to or removed from theshaft Q, as may be neeessary. To this end the adjacent radial arms of the two halves of the wheels are provided with flanges, in which are formed bolt-holes for the reception of bolts, by means of which the two sect-ions of the wheel are bolted together, and they are rigidly secured to their shaft in any well-known manner, such as by means of a key or pin or other wellluiown means.

\Vhen the frame T is adjusted by means of the set-screw t, so that the cutter will cut a square cut or one at right angles to the straight edge of the web or webs or the strips, as in Fig. 7, the spur-wheel 0 is employed to transmit the rotation of the shaft Q, to the cutter-shaft S. \Vhen, 011 the other hand, the frame is ad justed to cut an oblique out, then the wheel 0 I is removed and that 0' applied, whose teeth are slightly oblique, and the bearing q of the shaft Q, on the side of the driving-pulley g i. 0., on the sidebar, t'of the frame, is shifted to bring said shaft on a proper line or parallel with the shafts of the driving-gear, shown in Fig. 8.

By means of the described arrangement of cutters O O B and the adjustable cutter frame T it will be seen that a web or a number of webs of paper may not only be entlengthwise into as many strips as is possible within the capacity of the cutter-shafts c 0, but the said web or webs or strips may be cut erosswise,'

either at right angles to their straight edges or at oblique angles to said edges, according to the use made of the cuttings.

In the manufacture of envclopestheoblique cross cut is of great advantage, inasmuch as a material saving of paper is effected, a rhomboid-shaped sheet being thereby obtained, from which the blanks for the envelopes may be more economically cut or stamped.

As the web or webs or strips are cross-cut they fall upon an endless belt, A, that delivers them to an inclined table, M, on which they are stacked according to size and then removed.

In order to give the machineagreaterscope as to the sizes, either in width or length of the sheets to be cut, the frame F is extended vertically or carries a superposed frame, f. At the rear end of the upper frame-section, and 011 opposite sides thereof, are secured standards E, in which is mounted a fuleruurshaft, G. Upon opposite ends of this shaft are rigidly secured angle-levers L, the upper arms, Z, of which carry adjustable weights 10, while the lower arms, Z, of said levers are provided with or form bearings for the shaft h of a guide or tension drum, H, which is thus free to oscillate on the standards E under the varying tension of the paper. In front of the drum H are mounted two drawing-rolls, I 1, similar the arrangement being the same as that previously described, and said cutter-shaft, like the cutter-shaft S, is or may also be mounted upon an adjustable frame, T, in order to cut the continuous strips into rectangular sheets, or, if desired, into sheets or rhomboidal'form. On the right of the cutter-shaft Kis arranged a guide-bar, T of double T-iron, the righthand beveled edge, i of the upper horizontal portion of which projects between the draw-- ing-rolls I l to receive the strips of paper,

Whiletheleft-hand edge, t, of said uppervhorizontal portion constitutes the stationary cutter, and, together with the cutter K, cuts the strips transversely. Itis evidentthat by means of this arrangement any number of continuous webs of paper fed from rolls RR to cutters O C, and by them cut into given widths, may, after leaving the said cutters and the guiderolls 'r N, be taken up and carried overdrum H to drawing-rolls I I, and thence to cutter or cutters K, and cut into sheets of different lengths from those out by the knives below, so that the same machine will cut agreater varietyof sizes of sheets, and will cut them.

either rectangular or in rhomboidal form, or said machine may be made to cut rectangular and rhomboidal sheets at the same time, or any number of sheets may be taken to the upper mechanism after leaving the feed-rolls It R.

It is obvious thatinstead of delivering the paper from roll-s upon which such is wound, either by thepaper-makihg mechanism or otherwise, the continuous sheets may be fed to the machine directly from the paper-making ma chine.

If desired, the upper cutting mechanism may be provided with aset of cutters similar I to those 0 G and mounted on the right of the feed-rolls I I,to still further extend the scope of the machine, and I have deemed it unnecessary to show such an arrangement, as it is within the province of any skilled mechanic to apply the same from the description of the construction and function of the cutters G O. The cut sheets fall upon an endless apron, A, that delivers the same upon a table, N, in a manner and for purposes similar to those described with reference to the apron or belt A and table M;

The operating mechanism of the machine is driven from the shaftS of the drawing feedroll R of the lower set of drawing feed-rolls, said shaft carrying a loose and fast pulley, I P, the latter being belted to and driven from any suitable prime motor. The shaft S also carries a cone-pulley, P, a gear-wheeLWV, and belt-pulleys PI. The cone-pulley l? is belted to a like pulley, 2", on the shaft of the drawing-roll I, through which the upper portion of the mechanism is driven, whilethe gearwheel W meshes with a pinion, p, on the journal of the cutter-shaft c. The pinion p meshes with anidler, p and the latter with a pinion p on the upper. cutter-shaft. The pinion p on the upper cutter-shaft meshes with a second idler, 1), and the latter with a pinion p on thejournal of the lower guide-roll, 1*. .The 'knife-shaft S carries a gear-wheel, O and O, at its opposite ends within the cutter-frame T, that mesh with one of the wheels, 0 or 0, detachably secured to a counter-shaft, Q, that is mounted in bearings formed on the adjustable cutter-frame T, one of said bearings, q, being adjustable, as hereinabove fully described. In this manner, when the table is turned to cause the knives to cut obliquely to the straight edges of the continuous strips, there is no derangement in the driving=gearing, as plainly shown in Fig. 8.

The shaft Q carries a grooved or flanged pulley, q, that is driven by a belt, I), from beltpulley l on shaft S, above referredto, the belt I), Fig. 1, passing under and around ten sionpulleys m m m the latter being adjustable in its bearings by means of a set-screw, 8, as shown in Fig. 1, for obvious purposes. The endless apron or belt A travels over rollers a a and over tension-rollers a a a and under a tensionroll a, the roll a being adjustable horizontally toward or from the roll 'a, to give the apron or belt the proper tension. The shaft of the latter roll carries a beltpulley, d, that is belted, with the pulley P on shaft S, above referred to, and as shown in Fig. 3, through which pulley P the apron or belt A is operated.

As previously stated, the shaft of the roll I of the upper pair of drawing-rolls carries a conical pulley, i, that is belted with a like pulley, P mounted on the main drivingshaft S. The upper cutter-shaft, K, like cutter-shaft K, carries also two gear-wheels, g g, that mesh with either the gear-wheel v or the gear-wheel '0 on a counter-shaft, V, according to the ad- I justment of the cutter-frame, to cause the cutter to cut straight or obliquely. When cutting straight, the gcar-wheels 'l) g mesh with each other, and when the cutter cuts obliquely the wheels 1) g mesh with each other, the shaft V being first properly adjusted by adjusting its bearings on the adjustable frame. The countershaft V carries a grooved or flanged driving-pulley, V, that is belted to alike pulley, N, on shaft of drawingroll I, the belt I) passing under, around, and over tension-pulleys n a of, respectively, the pulley n being adj ustable vertically by means of a set-screw, 8*, as shown in Fig. 1. Finally, the feed apron o1 belt A passes over rollers e e and under and over tension-rolls e e, the latter of which is adjustable horizontally toward or from roller e by means of set-screws s to maintain the apron or belt at proper tension. The shaft of roller e carries a pulley, O"; belted to a pulley, 0 on shaft of drawing roll I.

It will thus be seen that all the operative parts of the machine are driven from the same shaft.

Having thus particularly described my said invention, What I claim, and desire to secure by Letters Patent, 1's- 1. A paper-cutting machine comprising a set of circular cutters for cutting the webs of paper longitudinally, a cross-cutter to which a portion ofthe longitudinally-cut Webs ofpaper are fed and by which they are cut transversely, a second cross-cutter for cutting transversely the remaining webs of paper, and a delivery apron and table for each of said cross-cutters.
