Improvements in Barbed Wire Fencing.
1 JAMES BERESFORD of 4 Keppel Road Chorlton-cum-Hardy near Manchester
in the County of Lancaster Manager do hereby declare the nature of this invention
to be as follows :-
My said invention relates to wire fencing haring projecting wire or other barbs
as is well understood. These barbs are generally speaking formed from short
lengths of wire, pointed at each end and mounted upon or intertwisted with a
double twisted strand composed of two round wires the double strand being
necessary to prevent the barbs from turning round as they would do if mounted
upon a single round wire. The object of my invention is to enable a double strand
of wire to be dispensed with the barbs being mounted upon a single wire and yet
prevented from turning or being moved or slid along the wire.
For the purposes of my invention I utilise the triangular section of wire which
forms the subject matter of an invention for which I have made application for Her
Majesty's Royal Letters Patent No. 18779 of 1889.
The said triangular wire is specially suited to receive and maintain in position
the said wire or other barbs as the triangular section of the wire prevents the barbs
from turning just as effectively as if a double strand of round wire were used as
at present.
To maintain the barbs in their proper position or pitch on the said triangular
wire, twist the wire into a spiral form as illustrated in the Specification attached
to my said former application after the barbs have been applied to or mounted
thercon. I might however in some cases dispense with this spiral twisting of the
wire. My invention may be used either in conjunction with the ordinary or usual
form of barb or with any other suitable form of barb either of wire or formed from
sheet metal. It will be evident that square, oblong or polygonal wire might be
used instead of my improved triangular wire as any of these sections would prevent
the rotation of the mounted barbs but triangular wire is preferable as it is lighter,
stronger in proportion to its appearance more economical and possesses advantages
not so apparent in other sections.
In some instances I might with advantage use my improved triangular wire
in conjunction with a strand of round wire the barbs being mounted upon the
round wire while the twisted strand of triangular wire would have the effect of
locking and holding the barbs in their proper and normal position.

Improvements in Barbed Wire Fencing.
I JAMES BERESFORD of 4 Keppel Road Chorlton-cum-Hardy near Manchester
in the County of Lancaster Manager do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings —
My said invention relates to wire fencing having projecting wire or other barbs
as is well understood. These barbs are generally speaking formed from short
lengths of wire pointed at each end and mounted upon or intertwisted with a double
twisted or cabled strand composed of two round wires the double strand being
necessary to prevent the barbs from moving or turning round as they would do if
mounted upon a single round wire. The object of my invention is to enable a
double strand of wire to be dispensed with, the barbs being mounted upon a single
wire and yet prevented from turning or being moved or slid along the wire.
For
the purposes of my invention I utilise the preferably a triangular section of wire
which forms the subject matter of an invention for which I have made-uppliention
for Her Majesty's Royal Letters Patent No. 13770 of 1830. The said triangular
section of wire is specially suited to receive and maintain in position the said wire
or other barbs as the triangular section of the wire prevents the barbs from turning
just as effectively as if a double strand of round wire were used as at present. To
maintain the barbs in their proper position or pitch on the said triangular wire I
twist the wire into a spiral form us illustrated in the Specification attached to my
said-former application after the barbs have been applied to or mounted thereon.
My invention may be used either in conjunction with the ordinary or usual form of
barb or with any other suitable form of barb-either of wire or formed from-cheet
metu!. It will be evident that square, oblong, or polygonal wire or wire-of-n
regular or irregular-section-other than round wire might be used instead of my
improved triangular wire as any such section would prevent the rotation of the
mounted barbs but triangular wire is preferable as it is lighter, stronger in
proportion to its appearance, more economical and possesses advantages not so
apparent in other the square section. In some instances I might with advantage
use my improved triangular wire in conjunction with-a-strand of round wire the
burbs being mounted upon the round-wire while the twisted-strand of triangulur
wire-would have the effect of locking and holding the barbs in their proper and
normal position.
To render my invention perfectly clear I will now proceed to describe the same
particularly with reference to the annexed sheet of drawings which clearly illustrate
the chief features of my invention.
Fig. 1 is a perspective view of a portion of my the herein before referred to
triangular wire.
Fig. 2 is an enlarged cross section of the same.
Fig. 3 4, and illustrates examples of the chief modified square section of wire
which might be used instead of my the said improved triangular wire.
Fig. 64 is a perspective view of a portion of triangular wire carrying a barb and
twisted to prevent lateral movement of the barb as already described.
Fig. 5 is a similar view except that in this instance the wire is prismatie square
in section.
Fig. 6 shows a portion of fencing formed from material made in accordance with
my invention.
The mode of carrying my invention into effect is very simple and may be
described in a few words. take the triangular wire a preferably before it has
been twisted and pass it through the ordinary barbing machine which cuts Gif and
twists the barbs & upon the wire a in the manner and by the means at present used
in the manufacture of barbed wire. The barbing mechanism being identical with

page_text: that at present used and forming no part of my invention I do not consider it
necessary to describe or illustrate the same. It will be obvious that the triangular
form of the wire a effectually prevents the twisted on barbs from revolving upon
the wire a as they would do if the wire were round. Now to prevent sliding lateral
movement of the barbs & on the wire a 1 twist the wire a upon its own axis into the
form shown at Fig 64 which has the effect of preventing the barbs b from being slid
or moved along the wire a. Thus by the double expedient of using a wire of
triangular section and twisting the saine, the barbs are practically locked in position
and are maintained therein as permanently and securely as if the usual second
binding wire had been employed. By my invention the expense of the usual
double wire and the labour of forming it is obviated and I obtain a stronger, neater,
lighter, and more efficient barbed fence at less expense than heretofore.
Although I have described my invention as particularly applicable in conjunction
with my improved wire of triangular section it will be perfectly obvious that a
similar though probably not quite so advantageous result might be obtained by the
employment of a carrying wire of a square section other than triangular wire
and-not-being-round wire. In using such substitutes for the triangular wire the
escentials-to-be observed are First that the wire should by virtue-of-its-own-cross
section prevent the burbs from revolving thereon and Second that the said wire
should be capable of being twisted upon its own axis so as to present-what will be
equivalent to stops on each side of the barbs and so prevent lateral or sliding
movement. Keeping these principles in view, which-are-really the gist and subject
mutter of my invention I will now-refer briefly to the forms of wire which might be
used instead of the triangular section. Such ancillary forms-might be of a prismatic
section as at Fig. 3 or of a square section as at Fig. 1 or of un-oval-or-elliptical
section ns-nt Fig. 5 or of an oblong or polygonal or semicircular-section or in short
any section of wire appreciably differing from a round section, as shewn at Fig. 3.
have however chosen specially to refer to the use of triangular wire as it is in my
opinion the most suitable section. Fig. 5 is an example of the prismatic square
wire barbed and iwisted in the manner above described with reference to the
triangular section. The view at Fig. 6 need no particular description.
I
In some cases-burbs other than the barbs /, for example-burbs-forined-from-sheet
metal might be used in conjunction with the aforesaid twisted-wire.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
In the manufacture of material for making barbed wire fencing, the employment
of single spirally twisted wires of triangular, or square, prismatic-oblong, elliptient
or other regular or irregular section not being a round section to carry the coiled on
barbs, the section and twist of the wire locking the barbs in position substantially
as described and shown.
