PROVISIONAL SPECIFICATION.
New or Improved Barbed Wire Netting and Fencing.
I, ROBERT PERKS YATES of Lyndhurst, Gravelly Hill near Birmingham in the
County of Warwick, Edge Tool Manufacturer, do hereby declare the nature of this
invention to be as follows:-
Heretofore, wire netting or what is commonly known in commerce as wire lettucing,
is made or woven continuously in such a manner, that the wires are prongless, or have
no out- outwardly extending protruberances proceeding from them. Thus, the wires
when interwoven constituting the netting, are left naked, and thereby affords no pre-
ventative against animals, such as rabbits, from pushing through the meshes or
burrowing under it.
The object of my invention, is to remedy these said defects, by providing the said
netting, or the wires constituting it, with prongs, barbs, or other sharp pointed pro-
jections, thus rendering the said netting a perfect preventative against burrowing,
occursion or displacement, as is done with wire netting as ordinarily made.
Besides the said netting confining animals as aforesaid, within certain areas, it also
affords a means of preventing incursions as well as occursions.
In carrying out my invention, I will first describe it in connection with ordinary
wire lettuce, whose meshes are hexagonal in form.
At the angles, or at the junctions of the sides of the said meshes, short prickle
lengths of wire are twisted in a manner that their spur like points are presented
outwardly or inwardly in planes at right-angles to the direction of the netting; so
that on a rabbit coming in contact, or presenting itself, or parts of its body to the
said netting, it becomes punctured or pierced, which being hurtful, causes the animal
to retreat, or desist from proceeding further.
The prickles, barbs or wire ends inay be made or woven with the netting, or they

fixedly secured in position, by galvanizing or tinning.
1 wish it to be understood, that I do not confine myself to the the dispositions of the
prickling barbs, as the same may be varied and applied in a multiplicity of ways;
and further, although I have described that the prickles, barbs or spikes are made
from short lengths of wire twisted about their middles upon the wire of the netting,
yet the said prickles, barbs or spikes may be cut out from sheet metal, and threaded
upon the wires during the process or processes of formation.
In applying my invention to strand fencing, I make the prickles or barbs from
sheet metal, cut out at a press, or I make them from wire fashioned with loops, which
are strung upon the strand or strands, and affixed in position at intermediate distances
apart, by galvanizing or tinning.
The prickles or barbs may be made staple-like, three-cornered, cruciform, star-shaped
or other like figure, and that the said prickles or barb blanks may be pierced with
holes for threading upon one, two, or more strands.
The prickle barbs may if necessary be produced by the casting process.

COMPLETE SPECIFICATION.
New or Improved Barbed Wire Netting and Fencing.
I, ROBERT PERKS YATES of Lyndhurst, Gravelly Hill near Birmingham in the
County of Warwick, Edge Tool Manufacturer, do hereby declare the nature of this

page_text: invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Heretofore, wire netting, or.what is commonly known in commerce as wire lettucing,
is made or woven continuously in such a manner, that the wires are prongless, or have
no outwardly extending protuberances proceeding from them-Thus, the wires when
interwoven, constituting the netting, are left naked, and thereby affords no preventative
against animals such as rabbits, from pushing through the meshes, or burrowing
under it.
The object of my invention is to remedy these said defects, by providing the said
netting, or the wires constituting it, with prongs, barbs or other sharp pointed pro-
jections, thus rendering the said netting a perfect preventative against burrowing,
occursion or displacement, as is done with wire netting as ordinarily made.
Besides the said netting confining animals as aforesaid, within certain areas, it also
affords a means of preventing incursions as well as occursions.
In carrying out my invention, I will first describe it in connection with ordinary
wire lettuce, whose meshes are hexagonal in form.
At the angles, or at the junctions of the sides of the said meshes, short prickle
lengths of wire are twisted in a manner that their spur like points are presented
outwardly or inwardly in planes at right angles to the direction of the netting; so that
on a rabbit coming in contact or presenting itself, or parts of its body to the said
netting, it becomes punctured or pierced, which being hurtful, causes the animal to
retreat or desist from proceeding further.
The prickles, barbs or wire ends may be made or woven with the netting, or they
may be attached thereto after-being made-In this latter, case, the prickles are fixedly
secured in position, by galvanizing or tinning.
I wish it to be understood that I do not confine myself to the dispositions of the
prickling-barbs, as the same may be varied and applied in a multiplicity of ways; and
further, although I have described that the prickles, barbs or spikes are made from
short lengths of wire twisted about their middles upon the wire of the netting, yet the
said prickles, barbs or spikes may be cut out from sheet metal, and threaded upon the
wires during the process or processes of formation.
In applying my invention to strand fencing, I make the prickles or barbs from
sheet metal cut out at a press, or I make them from wire fashioned with loops, which
are strung upon the strand or strands, and affixed in position at intermediate distances
apart by galvanizing or tinning.
The prickles or barbs may be made staple like, three cornered, cruciform, star-shaped
or other like figure, and that the said prickles or barb blanks may be pierced with
holes for threading upon one, two or more strands.
The prickle barbs may if necessary be produced by the casting process.
Figure 1 of the accompanying drawings, reprosents barbed wire netting, made
according to my invention, and it will be seen, that the lower part of the netting or
wire lettuce, is only barbed, while the upper part, or the meshes of the upper part of
the said netting, is left naked, or without barbs.
Thus, it is primarily the lower part that requires to be barbed, inasmuch as
incursions and occursions of rabbits and like animals, take place from the bottom. The
said lower and barbed part is shown turned horizontally, or at right angles to the
perpendicular fence, so as to lie under the ground, and thereby prevent burrowings
approximate to the said netting.
Figure 2 shows the said barbed wire netting or wire lettuce upon an enlarged scale,
with some of the barbs fully formed or made, whilst others are in their initial
stages: .
Figure 3 is a transverse section on the dotted lines A B figure 2, and figure 4 is a
barbed length before being twisted.
Figure 5 shows a section of a barbed mesh, with parts presented outwardly on the
two opposite sides, instead of on one side only.
The same letters of reference. indicate corresponding parts in the several figures.
u are the meshes of the wire netting, or lettuce, bare the completed barbs, which

page_text: are formed from barbed lengths figure 4, threaded through the end loops of end
twists a³, of the twists a³, as represented. Thus, the barb length b', is passed through
the loops of end twists a³, and then twisted as 62, 63, and from 6 to that of the completed
barbs b.
Figure 6 represents a piece of barbed netting, with the barbs formed from the wire
composing it, and which barbs are preferably cut or formed prior to the weaving of
the netting.
Figure 7 represents a portion of barbed wire netting, made according to another
form of my invention. The barbs are threaded on the wire of the netting, during the
process of its formation.
Thus, a barb figures 8 or 9, is first formed, and then during the process of the
weaving of the netting, is threaded into position, as the formation of the meshes
proceeds.
Figures 10 and 11 represent, strung barbs, cut out from sheet metal, or made by
casting. It will be seen that the said barbs are of various shapes, and may be pierced
with one, two, three or more holes, according to the number of wires requiring to pass
through them. These said barbs figures 10 and 11 are particularly applicable for
strand fencing, either twisted or plain.
Figure 12 represents a length of strand wire fencing, provided with strung sheet
metal barbs, which may be affixed by cranking the fence wire at the junction of it
with the barb, or compressing and thereby spreading out the said fence wire, and so
affixing the barb in its allotted position-Thus, a sheet metal barb c is threaded upon
a fence wire d, (see figure 13), then by pressure, the barb and fence wire is flattened
as in figure 14.
Although I have described and represented that the barbs or prickles are formed
from twisted wire, cut out, or cast barbs, woven with, or attached to the said netting,
yet I do not confine myself to the exact formation, or the means of attaching the
barbs.
Having now particularly discribed 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 :-
First Barbed wire netting, or wire lettuce, as set forth.
Secondly; Providing wire netting, or the meshes of wire lettuce, with barbs,
formed from the twisting of wire, or the threading of barbs around or upon the wires
of the said netting, substantially as and for the purpose as set forth in figures 1, 2, 3,
4, 5 and 7.
Thirdly-Barbed wire netting, or wire lettuce, formed by cutting or sliceing barbs
from the wires of, or composing the said netting, substantially as set forth in
figure 6.
Lastly;-Making the threaded-on barbs of wire netting and fencing, by cutting out
the same from sheet metal, or forming the same by casting, substantially as described
and set forth in figures 10, 11, 12, 13 and 14.
