This invention relates to barbed wire and to
a method of spooling it.‘
“
‘
'
Generally, barbed wire is sold in spools wound
projecting prongs. , For the sake of convenience,
it may be said that the‘ prongs are arranged in
fan form, the fan being con?ned within an an
upon a core or former and it is inconvenient to
gle of approximately 90° subtended about the
5 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
strand 4, and it will be seen that the fan extends
from the wire in substantially the same direction
provide a method of spooling barbed wire in a
manner which will avoid outwardly projecting
10 barbs. .Moreover, the invention is concerned
with forming the barbs in such a way as to ren
der it possible to spool barbed wire so that none
of the barbs project outwardly.
It will be appreciated that in the following
15 description the word “spooled” does not neces
sarily imply Wound on a spool or core, for ob
viously a material like barbed wire is sui?ciently
stiff for a central core to be dispensed with.
According to the present invention, barbed
20 wire is spooled so that its exposed convolutions
present their barbs inwardly. Preferably, all the
convolutions present unbarbed surfaces outward
ly, and in order to achieve this the barbs are pro
vided in units along the wire, and in accordance
with the usual practice each barb unit may com
prise one or a plurality of barbs, but where a
plurality of barbs are provided, it is essential, ac
cording to the present invention, that they are
arranged in fan form and con?ned within an
30 angle of 180° subtended about the strand, al
though it will of course be obvious that the barbs
are not necessarily in the same plane longitu
dinally of the strands. It is convenient in the
manufacture of barbed wire according to the in
35 vention 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 hel
40 ical 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 un
45 derstood and more readily carried into effect, it is
hereinafter described with reference to the ac
companying diagrammatic drawing, in which:
Figure 1 illustrates a short piece of barbed
Wire formed according to the present invention;
50 while
Figure 2 shows barbed wire spooled in a man
ner 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,
55 which is wound about a strand 4 and has two
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 ?at coiled, as indicated at 5, into 10
a long helical coil with the barbs all directed in- .
wardly, 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 15
helical coil 6 is then spooled by winding in the
manner shown, the axis of spooling being sub
stantially 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 0
arrangement shown all the barbs are directed in
wardly, with the result that a smooth outer sur
face is presented which is free from outwardly
projecting barbs, and although the wire prepara
tory to spooling in the manner above described
had all the barb fans pointing in substantially
the same direction radially of the strand, it will
5
be observed that as the strand is pulled sub
stantially axially of the flat coils 5, the action
is ?rst to turn the helices of each ?at coil through
an angle of 90° in opposite direction so that they
lie substantially in the same plane and substan
0
tially at right-angles to their original plane; dur
ing 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-an
gles 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.
Inter
mediate the handle
and the periphery of the
spool there may also be provided the sliding mem
ber 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 in 55

wardly, it will be necessary to twist the wire or
to bend the barbs so that an unbarbed exterior
surface may be presented after spooling has been
completed. Similarly, instead of the long heli
cal coil presenting throughout its length an un
barbed exterior, it need only present an unbarbed
surface at its exposed convolution so that pro
tection is afforded only so long as a spool of
barbed wire is in transit or store prior to actual
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 ?tting a carrying
frame to the spool.
