Improvements in Wire Netting.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton. Buildings, in the County of Middlesex, 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 :-
Wire netting of this class as at present constructed is commonly woven with an
approximately diamond-shaped mesh running longitudinally of the fabric. The
twists connecting the wires in this form are parallel, with each other and parallel
with the selvage. This netting is commonly used for poultry fencing and when
attached to posts easily sags between them owing to the position of the mesh.
Meshes of this construction readily yield to the longitudinal strain between the
posts which contracts its width. Should one of the selvage wires become broken
which is frequently the case in mounting the netting on posts the twists act pivotally
and afford little or no resistance to the vertical strain, permitting the netting to
collapse..
The longitudinal strain, moreover, when such break occurs in the selvage causes
the mesh at the point of fracture to draw together rendering it practically useless
as fencing and requiring constant repairing which becomes an item of considerable
expense to large users.
Numerous methods have been employed to strengthen such netting against the
vertical strain, as for example, inserting vertical wires in the meshes, making the

numerous disadvantages in addition to greatly increasing the cost.
My improvement is designed particularly to provide a netting which may be
formed from fine gage-wire woven in such manner that it will support its own
weight and not collapse from the vertical strain should the selvage break.
The fabric as produced by my improved method of weaving will not sag or
become distorted and is practically as rigid as a sheet of perforated metal standing
as much strain without being galvanized as many of the usual forms of netting will
after they have been so treated.
My said invention consists of a wire netting having mesh forming wires twisted
together, the twisted portion of each succeeding mesh being arranged at an angle to
that of the preceding mesh, and such portions running diagonally of the fabric, as
hereinafter described.
The accompanying drawing shows how my said invention is carried into
practice.
A B, represent the selvage wires with which the meshes formed by weaving the
wires d are connected.
In the forms of netting above described the frames in the machines containing
the twisting-segments are moved after forming the twist from the wires d, f from
right to left or in the opposite direction to engage with the wires that form the
next row of twists, these twists always running longitudinally of the fabric.
In my improvement after the twisting of the two wires d,f has taken place, I
carry the frames and twisting-segments both together in one direction for a
determined distance as for example from the points marked in the drawing to the
point i which is diagonally of the selvage. I then reverse one frame causing it and
its wire and segment to move laterally at an angle to the twist to a given position
;

page_text: as to j. At the same time the other frame and its segment and wire has travelled
on in alignment with the twist to a given distance as at k.
At the points j, k of movement the wires of the next adjacent meshes on either
side are met and have come into position to form the next row of twists, which are
carried diagonally in the opposite direction or at an angle to the first described
twist, when the. wires forming such succeeding twists are again spread by the
reversing of the frame.
This forms an elongated rectangular mesh C which runs diagonally of the fabric.
Alternate rows run in opposite directions. For example, all the meshes on the
line in the drawings are in parallelism while the succeeding vertical row of
meshes as on the line y, y while in parallelism with each other are at an angle to
those of the first row. Longitudinally of the fabric each row of meshes have a zig-
zag form and stand in such position that they will receive the vertical strain without
becoming distorted.

The position of the twists arranged consecutively at an angle to each other resist
such vertical pressure and practically form a series of trusses between the selvage-
wires.
This also prevents the doubling up lengthwise of the netting and forms a rigid
fabric.
The length of the twist between the points, hi, may be as desired, that shown
having two turns, but more or less may be employed. Neither is it essential that
such twists shall be equal in length to the plain portion of each mesh' as is shown,
as I can vary them in numerous manners, the longer the twist, however, the more
rigid will the fabric become.

Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim is :-
1st. A wire-netting comprising, mesh-forming wires twisted together, the twisted
portion of each succeeding mesh being arranged at an angle to that of the
preceding mesh, and such portions running diagonally of the fabric, substantially
as described.
2nd. A wire-netting having the wires forming the same twisted to form parallelo-
gramic meshes running diagonally of the fabric adjacent meshes being arranged at
an angle to each other substantially as set forth.
