EDWARD I. BRADDOCK, OF WINCHESTER, MASSACHUSETTS, ASSIGNOR T0 BRADDOCK NAIL & MANUFACTURING 00., OF CLEVELAND, OHIO, A CORPORATION OF DELA- WARE.

BARBED WIRE.

Patented Oct. 28, 1919.

Application filed Novemher 1, 1918. Serial No. 260,662.

To all whom it may concern .Be it known that I, EDWARD I. BRADDooK, a citizen of the United States, residing in "Winchestenin the county of Middlesex and State of Massachusetts, have invented an Improvement in Barbed Wire, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to barbed wire and has for its object to provide a superior barbed wire at a minimum expense.

To this end, I employ a single wire, strand or rod upon which are mounted a plurality of wires which are interconnected to form a barbed unit having a plurality of barbs extended at an angle to one another and having a fixed or permanent relation to one another.

The barbed unit is composed of two substantially short wires which are passed about the continuous or longitudinal wire so that their arms formed by bending the short wires about the continuous wire extend at an angle to each other and preferably substantially at right angles to each other, and an arm of one wire is bent about an arm of the other wire to interlock them and form a unit, in which the arms constituting the barbs are maintained in fixed or permanent relation to one another irrespective of the relation of the unit to the continuous or longitudinal wire and have the unbent arms substantially parallel and extended in opposite directions on opposite sides of a plane through the axial center of the longitudinal wire, and have the bent arms substantially parallel to each other and extended in opposite directions on opposite sides of a plane through the axial center of the longitudinal wire and substantially at right angles to the first-mentioned plane.

The continuous wire may be provided with collars or other means for limiting movement of the barbed units lengthwise of the continuous wire.

. The particular features of the invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of a portion of a barbed wire embodying this invention.

that their adjacent arms ex Fig. 2, a section on the line 2-2, Fig. 1.

Figs. 3, 4 and 5, details to illustrate the relation of the barbed wires before they are 'tudinal wire, rod or strand, and b, c, the

cross wires which are mounted on the wire a and are interconnected to form therewith the barbed wire unit shown in Figs. 1 and 2.

The cross wire I) is bent around the longitudinal wire a. to encircle the same and form arms 10, 12, (see Fig. 3) extended preferably at right angles to each other, and the cross wire 0 is bent about the longitudinal wire a to encircle the same and form arms 13, 14, (see Fig. 4) which extend preferably at right angles to each other, and the cross wires 6, 0 are preferabl arranged so i end substantially' at right angles to each other as shown in Fig. 5. After the cross wires 7), 0 have been arranged as represented in Fig. 5, they are interconnected or interlocked so as to form a unit, which is eflected by bending an arm of each cross wire around an arm of the other cross wire.

As represented in Figs. 1 and 2, the arm 13 of the cross wire 0 is bent around the arm 10 of cross wire I) and has its free end extended substantially at right angles to the arm 10, while the arm 12 of cross wire I) is bent around the arm 14. of cross wire 0 and has its free end extended substantially at right angles to the arm let, and in the opposite direction to the arm 13.

In this manner the cross wires are interlocked so as to form a barbed unit in which i the barbs have a fixed or permanent relation to one another even though the unit be free to turn on the continuous wire a and that the unit is provided with two pairs of substantially parallel barbs with the barbs of one pair arranged substantially at right angles to the barbs of the other pair.

Provision is made for preventing or limiting movement of the barbed units lengthwise on the continuous wire or rod a which may be accomplished in various ways and in the present instance, this is accomplished by providing the Wire a with a collar 20 for each unit on the opposite sides of which the cross Wires are located.

Claims.

1. A barbed ire comprising a longitu dinal Wire or rod, cross Wires coiled about the said Wire or rod to encircle the same and form arms, with an arm of one cross Wire bent about an arm of the othercross Wire to interlock them and form a unit in Which the unbent arms are substantially parallel and extended in opposite directions on opposite sides of a plane through the axial center of the longitudinal Wire and the bent arms are substantially parallel and are extended in opposite directions on 013- posite sides of a plane through the axial center of the longitudinal Wire or rodand substantially at right angles to the first-mentioned plane.

2. A barbed Wire comprising a longitudinal Wire or rod and cross wires looped name I to this specification.

directions across the longitudinal axis of said Wire or rod from opposite sides of the latter and substantially at right angles to said parallel arms and substantially parallel Witheach other.

3. Abarbed ire comprising a longitudinal Wire or rod having a collar, cross Wires passed about the longitudinal Wire on opposite sides of said collarto form arms and having an armof one cross Wire bent about an arm of the other cross Wire to interlock said cross ires and form a unit Whose armshavea fixed relation to one another.

In testimony whereof I have slgned "my EDWAR- I. BRADDOGK.
