METHOD OF SPOOLING BARBED WIRE l A 4 I 2 )n M Patented Aug. 10, 1937 UNi'iED srsras METHOD SPOOLING BARBED WIRE George Lawson Brown, Preston, England Application May 4, 1935, Serial No. 19,884' In Great Britain May 4, 1934 4 Claims. (01. -422) This invention relates to barbed wire and to a method of spooling it.

Generally, barbed wire is sold in spools wound upon a core or former and it is inconvenient to handle owing to the fact that a large number of barbs project out from the surface of the spool.

The present invention has for its object to provide a method of spooling barbed wire in a manner which will avoid outwardly projecting barbs. .Moreover, the invention is concerned with forming the barbs in such a way as to render it possible to spool barbed wire so that none of the barbs project outwardly.

It will be appreciated that in the following description the word spooled does not necessarily imply Wound on a spool or core, for obviously a material like barbed wire is suificiently stiff for a central core to be dispensed with.

According to the present invention, barbed wire is spooled so that its exposed convolutions present their barbs inwardly. Preferably, all the convolutions present unbarbed surfaces outwardly, and in order to achieve this the barbs are provided in units along the wire, and in accordance with the usual practice each barb unit may comprise one or a plurality of barbs, but where a plurality of barbs are provided, it is essential, according to the present invention, that they are arranged in fan form and confined within an angle of subtended about the strand, although it will of course be obvious that the barbs are not necessarily in the same plane longitudinally of the strands. It is convenient in the manufacture of barbed wire according to the invention to arrange the barbs in fan form and contained within an angle of approximately 90 subtended about the strand, and to spool the wire by flat coiling the strands into a long helical coil, with all the barbs inside, whereafter the long helical coil may be wound into a spool the axis of which is at right-angles to the axis of the long helical coil and substantially parallel with the major axis of the flat coils.

In order that the invention may be clearly understood and more readily carried into effect, it is hereinafter described with reference to the accompanying diagrammatic drawing, in which:

Figure 1 illustrates a short piece of barbed Wire formed according to the present invention; while Figure 2 shows barbed wire spooled in a manner also according to the present invention.

It will be seen by reference to Figure 1 that the barbs 3 comprise a short length of wire, which is wound about a strand 4 and has two projecting prongs. For the sake of convenience, it may be said that the prongs are arranged in fan form, the fan being confined within an angle of approximately 90 subtended about the strand 4, and it will be seen that the fan extends from the wire in substantially the same direction radially of the wire.

Dealing now with Figure 2, it may be said that the barbed wire as described with reference to Figure l is fiat coiled, as indicated at 5, into a long helical coil with the barbs all directed inwardly, as indicated at 3, that part of the long helical coil which has been drawn away from the remainder of the spool being indicated in the drawing by the reference numeral 6. The long helical coil 6 is then spooled by winding in the manner shown, the axis of spooling being substantially at right-angles to the long axis of the helical coil 6 and substantially parallel with the major axes of the flat coils 5. Although in the arrangement shown all the barbs are directed inwardly, with the result that a smooth outer surface is presented which is free from outwardly projecting barbs, and although the wire preparatory to spooling in the manner above described had all the barb fans pointing in substantially the same direction radially of the strand, it will be observed that as the strand is pulled substantially axially of the flat coils 5, the action is first to turn the helices of each fiat coil through an angle of 90 in opposite direction so that they lie substantially in the same plane and substantially at right-angles to their original plane; during this operation, however, no twisting moment is imparted, with the result that the barbs 3 will point in opposite directions, and in consequence when the wire is pulled taut adjacent fans of the barbs will be disposed more or less at right-angles to one another, as indicated in the stretched out end piece of wire by those barbs indicated with the reference numerals 3a and 3b.

It is convenient to spool the wire upon a core l, and for carrying purposes there is provided a stirrup or carrying frame 8, the cross piece 9 between the two arms serving as a handle. Intermediate the handle and the periphery of the spool there may also be provided the sliding member Ill, which may be pressed down to bear tightly against the periphery of the spool and prevent unwinding.

It will be appreciated that the invention so far as it concerns the method of coiling the barbed wire may be applied to all forms of wire, but where the wire is of such form that it is not naturally adapted to have the barbs directed infaces, which consists in flat coiling the strands.

into a long helical coil with its barbs presented inwardly and winding the long helical coil into a spool the axis of which is at right-angles to theaxis of the long helical coil.

2. The method of spooling barbed wire wound upon a core so that its exposed convolutions present unbarbed surfaces by flat coiling the strands into a long helical coil with the barbs presented inwardly, and winding the long helical coil into a spool the axis of which is at right-angles to the axis of the long helical coil, and fitting a carrying frame to the spool.

3. The method of spooling barbed wire which consists in flat coiling the strands into a long helical coil with its barbs presented inwardly by forming each barb unit as a single barb, adjacent barbs subtending an angle of less than one hundred and eighty degrees on the same side of the strand, and winding the long helical coil into a spool.

4. The method of spooling barbed wire so that itsv exposed convolutions present unbarbed surfaces which consists in flat coiling the strands into a long helical coil with its barbs presented inwardly, forming each barb unit of a plurality of barbs arranged in fan form and confined within an angle of one hundred and eighty degrees subtended about the strands, and winding the long helical coil'into a spool.
