DEVICE FOR MAKING BARBE D STRIPS FOR FENCES.

EPESIPICAIION forming part of Letters Patent No. 310,394, dated. January 6, 1835.

Application filed August 15, i594.

all whom it may concern:

Be it known that I, J osmn W. Ems, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pen 11- sylvania, have invented a new and improved barbed metallic strip or thin flexible rail for fences, and also a means for rapidly and cheaply making the same, of which the following is a specification.

My invention relates to that class of thin flexible metallic strips or rails which are provided along one or both edges with barbs or points integral therewitlnand used to deter animals from breaking or pushing down fences constructed of the same; and the improvement I have made consists of a thin metallic strip, of the form hereinafter described, divided 1ongitudinally by means of a rotating zigzagshaped sharpedged outting-disk, operatingin conjunction with a plain roll in such a manner as to slit the iron and form suitable barbs or angular points on each half of the strip along its line of cut and separation, all of which will be readily understood from the following description, taken in connection with the accompanying drawings, wherein- Figure 1 represents a front elevation of a stout frame containing a pair of rolls, one of which is plain, and the other provided with a sharp zigzag-edged cutting-disk of the character hereinbefore mentioned; Fig. 2, a trans verse vertical section of the same, including the guide-box in front of the rolls and receiving-plate behind them; Fig. 3, a vertical sec tion of the cutterroll with a portion of its shaft therein; Fig. 4, a portion of a plain thin strip of metal; Fig. 5, a similar strip of metal upon which is delineated the proposed zigzag out or line of separation. Fig. 6 represents one half of said strip, which is divided from the other half in such a manner as to form a series of sharp angular points along one edge thereof; Fig. 7, a portion of a ribbon or strip of metal, having along each side thereof a single l1alfround raised bead or rib so arranged upon the strip as that the reverse side, or that por tion of the strip directly opposite each rib or half-round bead, shall present a flat and plain surface; Fig. 8, a twisted longitudinal half of said metallic strip, having a half-round rib or raised bead along and upon one side only, and

with closely-connected angular points or barbs along one edge, whereby it is made suitable for fencing purposes.

To put my invention into practice, and thereby make barbed metallic flexible rails or fencin g-strips of the character hereinafterset forth, I provide a suitable frame, A, and place therein a pair of strong rolls, a a, each consisting of a shaft, 1), upon which is arranged and affixed a steel disk, 0, supported sidewise by stiff circular flanges. The face of the under roll, a, is plain and cylindrical, or parallel with its axis, or nearly so, being varied in that respect by its central disk, 0, which is a little larger than its side supports. The disk 0 of the upper roll, a, also projects outward beyond the immediate face of its side flanges, (Z, a distance equal to the thickness of such metallic strips it is intended to operate on, and is provided with a connected and solid series of V-shaped chisels, f, integral there: with, that together form a continuous sharp cutting-edgeextending completely around its periphery on a zigzag line, which is arranged directly over and as close to the plain face of the lower roll, 0, as may be without actual contact therewith, being adjustable in that relation by means of vertical screws g in the top of the frame A, whereby any passing strip may be divided or split longitudinally and not injure or spoil the cutters. The side flanges, d, of the upper roll, a, by a sudden increase of diameter at a proper distance from the cut tingdisk, form collars ii, that overlap the edges of the lower roll in such a manner as to prevent independent end-play or shifting of 4 relative positions.

Attached to the front of the frame A is a suitable guide-box, B, as a means for the proper introduction of metallic ribbons or strips to the joint action of the rolls; and at the rear of the frame A and opposite side of the rolls is a small table, D, for temporarily supporting the strip after being acted on. This construction of machine is very simple and substantial, and calculated to do the work required of it in a very rapid and satisfactory manner; and as the disks, with their side flanges, are readily detachable from the shafts, they can be removed for the purpose of sharpening, rehardening, or the substitution of new i I i verse] y to its length until its angular barbs I;

ones when and as the case may require. After the rolls have been properly adjusted and set in motion a strip of metal of suitable length. breadth, and thickness maybe intrqduced end foremost through the guide-box B to the rolls, whereupon it will be seized by them, carried along, and divided longitudinally in such a manner as to produce and form along its line of cut a connected series of angular teeth or sharp-pointed barbs.

Although I have shown in the drawings, Figs. 4-, 5, and 6, a plain strip of metal and the effect produced thereon by the rolls, yet I prefer to use a special strip, E, having one single'half-round rib or raised bead, 1', along each side thereof, not opposite one another, but so located as to be widely separate, so that the portion of the strip directly under each rib i shall present a perfectly plain sznooth surface, having nearly tlnee-t'ourths of its entire width on one side of the rib and onefourth on the other side, which shape is easier formed, is lighter, and much more flexible than when the ribs join. It also possesses that quality admitting of uniform and symmetrical twist without undue contortion or strain. This ribbed st rip E, when of proper size, and preferably cold, is to be entered end foremost through the guidebox B to the revolving rolls, which will split, divide, and separate it longitudinally in such a manner as to leave each part with a'peri'eetly plain side, and its opposite with a central rib, i, thereon, and one edge of the strip with a series of closely-studded triangular-shaped points, serrations, or barbs, 7;, after which each section or rail so produced and formed is to be twisted trans are disposed and arranged spirally all around it, and the rib is caused to appear first on one side and then on the other at regular intervals, by which a novel effect is created.

Having thus described my improved metallic barbed fence-rail, I clain1- 1. In a machine for forming barbed metallic rails or flexible strips for fencing, a circular disk provided with a connected. series of integral zigzag-shaped sharp cutting-edges, in combination with a plain-faced roll.

2. In a machine for forming barbed metallic rails or flexible strips for fencing, a detachable circular disk provided with a series of zigzag sharp cutting-edges integral therewith, and a flange on each side of the disk, in combination with a plain-faced roll.

3. In a machine for forming barbed metallic rails or flexible strips for fencing, a circular disk provided with a connected series of zigzagshapcd cutting-edges, made adjustable up or down in a frame, in combination with its side supportingflanges and a plain-faced roll.

In a machine for forming barbed metallic rails or flexible strips for fencing, a circular disk provided with a series of zigzag cutting-edges, in combination with a plain-faced roll and a guide-box leading to the space between them.

In a machine for forming barbed metallic rails or flexible strips for fencing, acircular disk provided with a continuous zigzag cutting-edge that is supported on each side by a flange, in combination with a roll contain ing a detachable plain faced disk arranged in close proximity to the cutting-disk, and operating jointly in such a manner as to sever strips of metal entered between them.

6. In a machine for forming barbed metallic rails or flexible strips for fencing, a circular disk provided with a sharp zigzag cuttingedge, in combination with a plain-laced roll, working in conjunction with the cutting-disk to sever strips of metal in such a manner as to leave sharp angular points on each along the line of cut and separation, a guide-box for properly directing such strips of metal to the cutting action of the sharp-edged disk, a table for receiving the strips after being cut, and a means for adjusting the cutting-disk toward and from the plain-faced roll.
