WALDEMAR FRIEDLAENDER, of Fenchurch Street, in the City of London,
"IMPROVEMENTS IN WIRE FOR FENCES a communication to me from abroad by
Henry Honour and Max Friedlaender, both of Ashburton, Canterbury, New
Zealand,
This Invention relates to that class of wire for fences which is provided with
barbs at suitable distances apart, serving to prevent cattle and all kinds of stock
from passing between the wires, or rubbing themselves against the same.
The fences are formed by stretching the wires between supports or posts driven
at suitable intervals into the ground, a number of such wires being placed one
above the other a suitable distance apart (depending on the purpose for which the
fence is intended), so as to form a fence of the desired height.
The objects of this Invention are:-
1st To construct the fence so that it is impossible for the stock to seriously injure
themselves by coming in contact with the barbs or "spurs on the wires.
و"
2nd To increase the strength and neatness of appearance of the wires.
3rd To effect an economy in the construction of the wires.
4th To prevent the possibility of the barbs or "spurs" being broken off or
working loose along the wires.
This Invention consists in forming the barbs or "spurs" with two, three, or
more points projecting outwards from a central portion, which is formed with a
bole in the centre, of a shape and size to permit it to be threaded on the wire to
be employed. These barbs or "spurs" may be formed of any suitable metal or
Din 71

"
material, and may be produced by casting, stamping, forging, or any other suitable
process. The points may either project outwards in a straight line from the central
portion or body, or they may be twisted or turned in any desired direction.
The barbs or spurs" thus formed are threaded upon a single wire of any
desired section (the hole in the central portion or body of the barbs.or "spurs
being made to correspond therewith), and placed at the required distances apart.
The wire is then, by any suitable means, pressed or distorted on each side of the
barbs or "spurs," so as to cause the metal to project beyond the sides of the hole
in the body of the barbs or "spurs," and thereby prevent the latter from shifting
along the wire.
Any suitable means may be employed for pressing the wire out or distorting it
on each side of the barbs or "spurs," a convenient mode of effecting this consisting
in the use of revolving rollers, with projections arranged on their peripheries the
necessary distances apart (depending on the distances between the barbs or
spurs"), so that as the wire is fed through the rollers, the projections on the latter
will grip the wire on each side of the barbs or "spurs," and thus alter the shape of
the wire at such parts.
"
"
If desired the wire may be made of rectangular or other suitable section, and
when the barbs or spurs are in the correct positions thereon, it may have a
partial twist produced in it, by any suitable means, on each side of the barbs or
"spurs," whereby the latter will be prevented from moving along the wire.
When desired to allow the barbs or "spurs" to remain capable of revolving in
their places on the wire (but at the same time without allowing them to-move
along the same), it will be necessary to make the wire_of_circular section, and the
hole in the central portion or body of the barbs or "spurs" to correspond therewith,
but of slightly greater diameter, and then by pressing out or distorting the wire ou
each side of the barbs or "spurs," as described, the latter will be left free to revolve
on-the portion of the wire which remains unaltered in shape between the flattened
or widened parts on each side of the barbs or "spurs."

WALDEMAR FRIEDLAENDER, of Fenchurch Street, in the City of London,
"IMPROVEMENTS IN WIRE FOR FENCES," a communication to me from abroad by
Henry Honour and Max Friedlaender, both of Ashburton, Canterbury, New
Zealand,
This Invention relates to that class of wire for fences which, is provided with
barbs at suitable distances apart, serving to prevent cattle and all kinds of stock
from passing between the wires, or rubbing themselves against the same.
The fences are formed by stretching the wires between supports or posts driven
at suitable intervals into the ground, a number of such wires being placed one
above the other a suitable distance apart (depending on the purpose for which the
fence is intended), so as to form a fence of the desired height.
The objects of this Invention are:-
1st. To construct the fence so that it is impossible for the stock to seriously injure
themselves by coming in contact with the barbs or "spurs" on the wires.
2nd To increase the strength and neatness of appearance of the wires.
3rd To effect an economy in the construction of the wires. -
"
4th To prevent the possibility of the barbs or spurs" being broken off or
working loose along the wires.
"
"
This Invention consists in forming the barbs or "spurs" with two, three, or more
points projecting outwards from a central portion, which is formed with a hole in
the centre, of a shape and size to permit it to be threaded on the wire to be
employed. These barbs or spurs may be formed of any suitable metal or
material, and may be produced by casting, stamping, forging, or any other suitable
process. The points may either project outwards in a straight line from the central
portion or body, or they may be twisted or turned in any desired direction.
"
The barbs or "spurs" thus formed are threaded upon a single wire of any
desired section (the hole in the central portion or body of the barbs or "spurs
being made to correspond therewith), and placed at the required distances apart.
The wire is then, by any suitable means, pressed or distorted on each side of the
barbs or "spurs," so as to cause the metal to project beyond the sides of the hole in
the body of the barbs or "spurs," and thereby prevent the latter from shifting
along the wire.
Any suitable means may be employed for pressing the wire out or distorting it
on each side of the barbs or "spurs," a convenient mode of effecting this consisting
in the use of revolving rollers, with projections arranged on their peripheries the
necessary distances apart (depending on the distances between the barbs or
spurs "), so that as the wire is fed through the rollers, the projections on the latter
will grip the wire on each side of the barbs or "spurs," and thus alter the shape of
the wire at such parts
"
If desired the wire may be made of rectangular or other suitable section, and
when the barbs or "spurs are in the correct positions thereon, it may have a
partial twist produced in it, by any suitable means, on each side of the barbs or
"spurs," whereby the latter will be prevented from moving along the wire.
T
When desired to allow the barbs or "spurs" to remain capable of revolving in

page_text: their places on the wire (but at the same time without allowing them to move
along the same), it will be necessary to make the wire of circular section, and
the hole in the central portion or body of the barbs or "spurs" to correspond
therewith, but of slightly greater diameter, and then by pressing out or distorting
the wire on each side of the barbs or "spurs," as described, the latter will be left
free to revolve on the portion of the wire which remains unaltered in shape between
the flattened or widened parts on each side of the barbs or spurs."
"
But in order that this Invention may be fully understood I will proceed to
describe the same by the aid of the accompanying sheet of drawings.
Fig. 1 is a side elevation and Fig. 2 a plan view of a portion of a single circular
wire with two barbs or "spurs" secured thereon according to this invention. Fig. 3
is an end view of one of the barbs or "spurs," and Fig. 4 a similar view of the
other barb or "spur."
A is the single circular wire; B one of the barbs or "spurs" formed with four
points alternately twisted in opposite directions on both sides of the central portion
or body B'; and C is the other barb or "spur" also formed with four points which
project outwards in a straight line from the central portion or body C¹. In the
central portion or body of each of the barbs or "spurs" a circular hole D is formed
of slightly larger diameter than that of the wire A. The barbs or "spurs" are
threaded-upon the wire A, and placed at any required distances apart. The wire
is then pressed out or distorted on both sides of each barb or "spur"
as shown
at E, E', E, E, so as to cause the metal to project beyond-the-sides of the hole in
the body of the barbs or "spurs," and thereby prevent the latter shifting along the
wire, while at the same time they will be free to revolve on the part of the wire
which remains unaltered in shape between the distorted parts on each side of the
barbs or "spurs."
"
Fig. 5 is a side elevation, and Fig. 6-a-plan view of a portion of a single wire of
rectangular cross section, with two barbs or "spurs "secured thereon, according to
a slight modification of the method shown and described with reference to
Figures 1, 2, 3 and 4. Fig. 7 is an end view of one barb or "spur" with twisted
points, and Fig. 8 an end view of the other barb or "spur" the points of which are
in a straight line with the central portion or body.
Similar letters are employed to indicate corresponding parts in all the figures.
The hole D in the central portion or body of each barb or "epur" is of corre-
sponding form to the cross section of the wire, but of slightly larger dimensions.
When the barbs or "spurs" are threaded on the wire A, and placed at the required
distances apart, they are prevented from shifting along by twisting the wire on
each side of each barb or "spur" as shown at F, F, F, F³. This might also be
effected by pressing out or otherwise distorting the wire on each side of each barb
or "spur."
"
Any suitable means may be employed for pressing out, twisting, or otherwise
distorting the wire on each side of the barbs or "spurs."
Figs. 9, 10 and 11 show barbs or "spurs" formed with two, three, and five
points respectively, and it will be readily understood that such number may be
varied to any desired extent without departing from the principle of this invention.
And further, such barbs or "spurs," and also the wire on which they are secured
may be formed of any suitable material, and by any known method and any
suitable means.
Having thus described the nature of the said invention, and the manner of
carrying the same into effect, I wish it to be understood that what I claim is :-
The improved wire for fences consisting of barbs or "spurs" with any desired
number of points projecting outwards from a central portion or body, in which a
hole is formed so as to enable them to be threaded upon a single wire of a section
corresponding in form with, but slightly smaller than the hole in the central
portion or body of the barbs or "spurs," such barbs or "spurs" being placed at
suitable distances apart on the wire, and prevented from shifting along the same

page_text: by pressing out, twisting, or otherwise distorting the wire on each side of every
barb or "spur," by any suitable means, all substantially as and for the purposes
herein described and shown in the drawings.
In witness whereof, I, the said Waldemar Friedlaender have hereunto set my
hand and seal this twenty-first day of May, in the year of Our Lord, One
Thousand Eight Hundred and Eighty-three.
W FRIEDLAENDER (L.S.)
