IMPROVEMENTS IN WIRE NEETING
Year: 1881

page_text: LETTERS PATENT to William Henry Johnson, of Manchester, in the County
of Lancaster, Merchant, for an Invention of "IMPROVEMENTS IN WIRE
NEETING"
PROVISIONAL SPECIFICATION left by the said William Henry Johnson at
the Office of the Commissioners of Patents on the 9th August 1881.
WILLIAM HENRY JOHNSON, of Manchester, in the County of Lancaster,
Merchant. "IMPROVEMENTS IN WIRE NETTING."
My improvements relate to wire netting, and consists in furnishing such netting
with spikes or spines, such spikes or spines tending to prevent persons or animals
pressing against or climbing over and thereby injuring such wire netting aforesaid..
The aforesaid spikes or spines I form of separate pieces of wire, attached to the
netting by being twisted around the meshes thereof, the ends of the aforesaid
pieces of wire being pointed and bent outward so as to constitute spikes or spines.
Or I incorporate into the netting an extra wire or wires during the manufacture of
the said netting, such extra wires I afterwards sever at intervals, and the ends of
wire produced by such severance I bend outwards so as to constitute spikes or
spines; or I form spikes or spines of separate pieces of metal and attach them in.
any convenient manner to the said wire netting.
I also propose in some cases to use, either separately or in combination with the
above, a band or bands of metal having teeth or spikes formed thereon, such band
or bands of metal aforesaid being interlaced with the netting either during its
manufacture or subsequent thereto, the aforesaid teeth being formed in the previously
mentioned band or bands of metal either before or after being interlaced with the.
netting; or I form spikes or spines of separate pieces of metal or wire, and attach
them in any suitable manner to the aforesaid band or bands of metal.

WILLIAM HENRY JOHNSON, of Manchester, in the County of Lancaster,
Merchant. "IMPROVEMENTS IN WIRE NETTING."
My improvements relate to wire netting, and consists in furnishing such netting
with spikes or spines, such spikes or spines tending to prevent persons or animals
pressing against or climbing over and thereby injury such wire netting aforesaid.
The aforesaid spikes or spines I form of separate pieces of wire, attached to the
netting by being twisted around the meshes thereof, the ends of the aforesaid pieces
of wire being pointed and bent outward so as to constitute spikes or spines. Or I
incorporate into the netting an extra wire or wires during the manufacture of the
said netting, such extra wires I afterwards sever at intervals, and the ends of wire
produced by such severance I bend outward so as to constitute spikes or spines; or
I form spikes or spines of separate pieces of metal and attach them in any con-
venient manner to the said wire netting. I'also propose in some cases to use, either.
separately or in combination with the above a band or bands of metal having
teeth or spikes formed thereon, such band or bands of metal aforesaid being
interlaced with the netting either during its manufacture, or subsequent thereto,
the aforesaid teeth being formed in the previously mentioned band or bands of
metal either before or after being interlaced with the netting; or I form spikes or
spines of separate pieces of metal or wire, and attach them in any suitable manner
to the aforesaid band or bands of metal. In order that my Invention may be more
readily understood and carried into effect, I will now proceed to describe the same,
reference being made to the accompanying Drawings, of which Figure 1 shews the
first part of my Invention. At 1. are the wires forming the wire netting, 2 being the
wires forming one of the selvage edges; I take pieces of wire 3, which I twist around
the selvage wires as at the points A; the ends of the wires 3 I allow to project and
constitute spikes or spines, as at 3*, 3**; or instead of attaching the wires forming the
spikes or spines to the selvage, I twist such wires around the wires forming the surface
of the netting, as at A*, A**. The points of the spikes or spines 3*, 3**, may be
bent so as to project in any direction as may be desired, or caused to project
alternately from either side of the netting, or may project from one surface of the
netting only; the next part of my Invention is shewn by Figure 2. At 4 are the
wires forming the netting, and during the process of manufacture. I incorporate.
therewith extra wires, as at 5, which I subsequently sever at or about the points B,.
and then the ends produced by such severance I bend in any desired direction, so
as to constitute spikes or spines, as at 6; or instead of incorporating one wire
only, as shewn at. 5, I incorporate two or more wires with the netting, which wires
upon being severed will form a compound spike or spine, as shewn at 7, which is
a spike or spine formed by two pieces of wire. The next part of my Invention is
shown by Figures 3, 4, and 5. In this instance I form the spikes or spines of.
separate pieces of metal which I attach to the netting. Figure 4 is a front view,
and Figure 5 a side view of a spike or spine formed either by casting, stamping,
or in any convenient manner, and formed in two portions, one constituting a clip
by which it is attached to the netting, the other portion forming the spikes or,
spines. At 8 are the spikes or spines, 9 being the portion by means of which they
are to be attached to the wire or wires forming the netting. The curved part of
the spike or spine 8 is placed upon the wire or wires forming the netting, and is
then bent or closed upon the wire or wires so as to tightly embrace it or them, as
shown by Figures 6 and 7, in which the part 9 is shown closed around the wire or

page_text: wires 10. Figure 3 shows a portion of wire netting with spikes or spines, as
illustrated by Figures 4 and 5, attached thereto, such spikes or spines may be
either applied to the selvàge of the netting, as at C, or to the surface thereof, as
at D, or to the selvage and surface, together or separately, as may be desired. The
next part of my Invention is shown by Figures 8 and 9; in this instance I
interlace a band or bands of metal 11 with the wire netting 12. Such interlacing
of the bands 11 with the netting 12 may take place during the process of its.
manufacture or subsequently thereto, as may be found most convenient. Upon
the band or bands 11 I form teeth or spikes 13, such teeth or spikes being bent so
as to project from the band or bands 11, as shown in the plan, Figure 9; or instead
of forming the teeth or spikes 13 by cutting or notching the band or bands 11,
I propose in some cases to form teeth or spikes of separate pieces of metal, as
shewn in Figures 10 and 11, of which Figure 11 is an elevation, and Figure 10 a
plan of such tooth or spike. The spike or tooth consists of two portions, a part 14
for embracing the band of metal interlaced with the netting, and the part 15
forming the teeth or spikes. These teeth or spikes may be formed by casting,
stamping, or in any convenient manner, after which they are attached to the band
or bands of metal interlaced with the netting 12, as shown at E in Figure 8. By
affixing spines, spikes, or teeth to the selvage or the body of the wire netting, such
spines, spikes, or teeth forming projecting points, tend to prevent persons or
animals pressing against or climbing over and thereby injuring such wire netting
aforesaid. In the foregoing description and accompanying Drawing I have only
indicated some of the methods of forming spikes, spines, or teeth upon wire netting,
but it will be readily understood that such spines, spikes, or teeth may be formed
of wires or bands of metal incorporated in the netting during or subsequent to the
manufacture of the wire netting, or formed separately and attached to the said
netting in a variety of ways.
Having now described the nature of my said Invention and the manner of
carrying the same into effect, I desire it to be understood that I claim as secured
to me under the above in part recited Letters Patent, the use of spines, spikes, or
teeth in combination with wire netting, substantially in the manner and for the
purposes above set forth and described.
In witness whereof, I, the said William Henry Johnson, have hereunto set
my hand and seal, this Tenth day of January, in the year of our Lord One
thousand eight hundred and eighty two.
