SANDY M. KANE, OF DES MOINES, IOWA, ASSIGNOR TO WVILLIAM L. OAR- PENTER, OF SAME PLACE.

BARB-WERE MACHINE.

SPECIFICATION forming part of Letters Patent No. 301,127, dated July 1, 1884:.

Application filed March 24, 1884. (Model.)

To all whom, it may concern Be it known that I, SANDY M. KANE, a citizen of the United States, residing in Des Moines, in the county of Polk and State of Iowa,have invented a new and useful Improve-- ment in Barb-Wire Machines, of which the following is a specification.

The object of this invention is to provide a device for turning or arranging the barbs as Io the two strands of the cable are twisted together, so that the prong side of the barb will always lie between the strands, and the prongs thus project centrally from the cable. \Vhen the barbs are thus arranged, the other strand I 5 of the cable effectually prevents their rotating or turning on the strand upon which they are placed, and the barbs being arranged unii'ormly, a better, more uniform, and more efficient barb-wire is produced.

The invention consists in a device having an oblong vertical slot, through which the barbwire passes, and an eye-hole for the plain wire. The walls of this oblong vertical slot are beveled, and the one adjacent to the plain wire is provided with a deep V-shaped notcli facing the barbing-inachine, the edges of which notch are beveled off, so as to turn the barb into a vertical position as it passes through the slot.

The opposite wall or edge of the slot is provided with a shallow curved notch the edges of which are also beveled off, so as to aid in turning and arranging the barbs. This device is located between the barbing mechanism and the twister, and in such relation to the twister that the twist of the cable will grasp the barbs at the proper distance from the device to cause the points of the barb to project from between the cables. The peculiar form of the two walls of the slot, together with their bevel edges, operate as a screw in twisting or turning the barb into the right position to be laid between the cable-wires.

In the accompanying drawing, which forms a part of this specification, I have shown a device embodying my invention as applied to a barb-wire machine.

In said drawing, A represents a portion of the frame of the machine, located between the coiling-head B and the mouth of the twister through.

, edge d", so that the barb will be gently turned 0, to which portion of the frame my barb turning and arranging device D is adjustably secured by means of the set-screw D, so that it may be adjusted to or from the twister, as may be desired, to cause the barbs to be properly laid between the strands of the cable. The device D is provided with an oblong slot, cl, which should be somewhat longer than the barbs and a little wider than the transverse thickness of the barbs. The face of the wall or slide D of this slotis provided with a deep V.-shaped notch, d, and also with a projection, d having a hole, (1, for the plain wire to pass The apex of this V-shaped notch (1 should project considerably below the eye d for the plain wire. The lower edge, (1", of 65 this V-shaped notch is rounded off both outwardly and inwardly, so that there may be no point for the barb to catch against. The upper edge of this Vshaped notch is beveled off inwardly at its lower portion, (1, and outwardly at its upper portion, d so as to present a screw-shaped edge. The opposite wall or side, D is provided with a bevel edge, d facing the coiling mechanism, and also with a V-shape or curved notch, d", the edges of which notch are also beveled inwardly. The edge of the top part, d, facing the coiler, should also be beveled inwardly. The notch d is made much shallower than the notch d, and its apex is above the former and about on the line with the wires as they pass through the device. As

the barb-strand a passes through the slotted device one of the prongs of the barb will first strike against the inwardly-beveled edge cl of the side D, and is thereby turned upward and onward by said bevel edge (1". This prong of the barb will ordinarily first strike against the lower portion of the inwardly-beveled notch d, which constitutes the middle portion of the o upward as the strand a is drawn through the slot. The opposite prong of the barb will then, as it is carried forward, strike against the inwardly-beveledlower portion, (1, of the side D", and the barb is then further turned by the screw edge of the side D until it is brought to a vertical position, when it passes through the slot and issues therefromin a vertical position.

by the twist and laid with their points pro- IO jeeting between the two strands of the cable.

I have described the device as being placed in a vertical position; but it, of course, may be set in other positions on the machine.

I claim 1. The barb-arranging device D, provided with an oblong slot for the barb-wire and an eye for the plainwire, the walls of said slot having notched bevel edges facing the barbcoiling device, substantially as specified.

2. The barb arranging and guiding device having an oblong slot for the barb-wire, and a wall or side adjacent to the plain wire, pro

vided with a beveled-edge notch for turning the barbs, substantially as specified.

3. The device D, having slots for the barbwire, eye (1 for the plain wire, side D having deep V-shaped notch d, provided with bevel edges, and the side D", provided with shallow beveled-edge notch d, substantially as specified.

4. The barb-arranging guide or device D,

provided with slot (1, and bevel-edged walls D D, said wall D having an eye, d", for the' plain wire and V-shape notch d, having lower rounded edge, d and upper edge beveled inwardly at its lower portion and outwardly at its upper portion, and said wall D having a bevel-edged notch, al the apex of which is located above the apex of the notch d, on the opposite edge, substantially as specified.
