PAPER-CUTTING MACHINE.

SPECFFICATION forming part of Letters Patent N01307,372, dated October 28, 1884- I Application filed May 18, 1883. (X modehl is so constructed that the paper will be cut as rapidly as it is rolled up, and thus the danger of tearing the paper bands or strips is avoided.

My invention consists in the peculiar construction and arrangement of the parts, as-

; hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved paper-cutting machine. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 8 is a plan view of the same, parts being broken out. Fig. etisacross sectional elevation through the cutter-shafts. Fig. 5 is an edge view of the cutters.

The paper, A, to be cut is wound on a drum or shaft, B, journaled in arms at one end of frame C, and from the drum or shaft 13 the paper is passed over a tension-roller, D, from there partly around a drum, E, then partly around a drum, F, above and between the drum E and the rollerD. Itthenpassesunderatension-roller, G, j ournaled in vertically-slotted standards G, containing rods G surrounded by springs G for pressing the said roller G downward. The paper then passes over a roller, H, and over a platform, I, in front of which the shafts J J are arranged, on which shafts the circular cutters or disks K K are loosely mounted. The strips A, into which the paper web A has been cut, pass between two rollers, L, in front of the cutting-disks, and are secured to two separate rollers, M M, on which they are wound. Thelower cutter-shaft, J, isfixed; but the upper one, J, is journaled in a series of arms, N, hanging downward from slides N, to which they are pivoted, which slides slide on standards 0, and are provided with racks O,

with which cog-wheels P engage, mounted 011 a shaft, 1?, journaled in jaws of the standards, and provided with a lover or handle, P The standardsO are provided with binding-screws Q, for locking the slides in place. The cutterdisks K are mounted to slide longitudinally on the shaft J, and .toturn with the same, and are held between an arm, R, of a block, R, sliding on the bar S in front of and below the shaft J, and a spring-finger, '1, held to a rod, T, adapted to slide transverselythat is, at right angles to the bar S in the blocks R. The blocks R can be locked in place on the bar S by means of binding-screws R and rods T can be locked in place in the blocks R by means of binding-screws T The rollers L are journaled in frames or plates U, pivoted to the sides (if the frameO in such a manner that the rollers L can be swung upward and from the cutter-shafts, and which plates U are provided with segmental slots U, through which a binding screw or pin passes into the frame 0, for locking the said frames U in the desired position. The cutter-disks K on the upper cuttershaft, J, are provided with binding'screws V, for locking them in place on the shaft. The driving-shaft XV is provided with belt-pulleys a and a pinion, I), engaging with a cog-wheel, c, which engages with a cog-wheel, d, on the end of the lower drum or shaft M. An intermediate cog-wheel, e, engages with the cogwheel (1 on the end of the lower drum or shaft M, and with acog-wheel, f, on the upper drum or shaft M. A cog-wheel, g, is mounted on the end of the drum E, and engages with a cog-wheel, h, on the end of the roller F, and a cog-wheel, j, journaled on the frame 0, and engaging with a cog-wheel, It, made integral with a larger cog-wheel, Z, engaging with a pinion, m, mounted on the lower cutter-shaft, J. Pinions a and a are mounted on the lower and upper cutter-shafts, respectively, and engage with each other. A brake-shoe, 0, is secured to the upper end of a lever, 10, pivoted to the side of the frame 0, and having its lower end pivoted toarod, q, havingathreaded part passing through a nut, r, on the frame 0, which rod is provided with a hand-wheel, s. A pulley, t, against which the brake-shoe can be pressed, is rigidly mounted on the shaft B. 100

20 is driven by the paper.

The shoe is pressed against the pulley t by turning the shaft q by means of the hand-wheel s, and the brake-shoe is released from the wheel t by turning the shaft q in the reverse direction by means of the hand-wheel s.

The operation is as follows: The drums or shafts M M are revolved in the direction of their arrows by the cog-wheels above described from the driving-shaft W, and consero quently draw the paper in the direction of the arrow to through the machine. The paper in passing over the drum E revolves the same, and the roller F assists. The motion of the drum E is transmitted by the above-described I 5 gearing to the cutter-shafts, which are revolved 2 5 moves slowly, the knives cut slowly. By means of tension-roller G the desired tension can be given to the paper to enable it to revolve the drum E, the roller I and the other above-mentioned parts. By pressing the brake-shoe 0 0 against the pulley t the too rapid uncoiling of the paper can be prevented. The cutter-disks K K can easily and rapidly be adjusted laterally on the shafts J J, according to the width.

of the strips or bands desired. As the lower 3 5 cutter-disks, K, are held at one side by a springfinger, they can givelaterally, if necessary, and are always pressed against the corresponding upper disks. The upper cutter-shaft, J, can

be adjusted vertically, so that the upper cut- 40 fer-disks overlap the lower disks more or less, and the upper blades can be held raised while introducing the uncut paper into the machine. The rollers L L can be adjusted so that they will always be about midway between the horizontal planes of the rollers H M.

mounted to turn and slide longitudinally 011 W their shaft, combined with an adjustable block havingan arm and a spring-finger, between which a cutter or disk is held, substantially as herein shown and described, and for the purpose set forth.

In a paper-cutting machine, the combination, with the shafts J' J, of the disks K on the shaft J, the disks K,'held to turn and fitted to slide on the shaft J, the sliding block It, having an arm, It, the rod T, passing through the block 1%, and of the spring-finger T on the end of the rod R, substantially as herein shown and described, and for the purpose set forth. 4. In apaper-cutting machine, the-eombination, with the cutting-disks, of the receivingrollers, rollers L L, and the pivoted frames U, in which the rollers L are j ournaled, substan tially as herein shown and described, and for the purpose set forth.

5. In a papercutting machine, the combination, with the cutting and pulling devices, of the drum E, around or over which the paper is passed, and of devices, substantially as described, for transmitting the motion imparted to the drum by the paper to the cutting de vices, substantially as herein shown and described, and for the purpose set forth.
