Improved Wire Netting and Method of Manufacturing same.
I, OLIVER IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, 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:-
This invention relates to the manufacture of wire netting and consists essentially
in making it by pressing one set. of wires (say for instance those which in weaving
are called the warp wires) on to another set of cross wires (say for instance those
which in weaving are called the weft wires) with sufficient force to make
an approximately U-shaped bend in each of the second set of wires where-
ever they are intersected by the first set and then in pinching the necks of the
bends together so as to almost entirely encircle each of said first set of wires, and
thus form a permanent connection between the two sets. In order to increase the
strength of the joints thus formed, the netting may be passed through a bath of
liquid metal such as zinc if preferred. Instead of making the U-shaped bends by
pressing one set of wires on to the other they may be made in the first instance, and
the other set be laid or placed within such bends, the necks of which must be
afterwards pinched together as before:
It is obvious that either the weft wires may be pressed or pinched on to the warp
wires or the warp on the weft or the two sets can be arranged diagonally. It is
preferable however to press or pinch the warp wire into the weft as by that means
the warp wires are left intact, and a netting is produced that can be stretched
without becoming baggy.
Referring to the accompanying drawings,―
Figures 1 to 5 are views illustrating the manufacture of wire netting according
to this invention whilst,
Figure 6 is a perspective view of a piece of such wire netting.
The same letters of reference indicate the same parts in all the figures.
A represents one of a set of wires (say for instance the warp wires) and B one
of another set (say for instance the weft wires) whilst represents one of the
approximately U-shaped bends formed within each of the second set when the
first set of wires are pressed on to them, the result being as illustrated in Figure 3,
that the wires A will rest within the lower parts of the bends b. The necks of
such bends are then pinched together so as to almost encircle the wires A, ns
illustrated in Figure 4, after which the netting may be passed through a bath of
molten metal, such as zinc, in order to strengthen the joint, and thus complete the
manufacture of the netting as illustrated in Figures 5 and 6.
The U-shaped bends above referred to can be made in one set of wires by means
of suitably arranged stamps or other contrivances, and the other set of wires can
then be pressed into them by hydraulic or mechanical pressure, as will be well
understood by all persons who are skilled in the art of wire working.
With this method of manufacture a square meshed netting is produced, which
is stronger and less expensive than the ordinary wire netting, aud which can be
manufactured with less complicated machinery.
Wire netting manufactured according to this invention can be used for any
purpose for which ordinary wire netting is adapted, and it can also be used for

page_text: fencing, as illustrated in Figure 7, which represents a short length of cattle fence
constructed with this improved wire netting.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is-
First. As a new article of manufacture wire netting in which one set of wires
has been forced or placed in approximately U-shaped bends in another set of
wires extending across the first set and in which the necks of such bends have
subsequently been pinched together, such joints being strengthened, if preferred,
by being passed through molten metal, such as zinc, substantially as aud for the
purposes herein described and explained, and as illustrated in the accompanying
drawings.
Second. The method of manufacturing wire netting, substantially as herein-
described and explained.
