Improvements in the Manufacture of Wire Netting and the like.
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 to be as follows:-
My invention relates to Improvements in the Manufacture of Wire Netting and
the like.
woven with an
As at present constructed wire-netting of this class is
approximately hexagonal mesh the twisted portions of the wires forming said
meshes running parallel with the selvage and longitudinally of the fabric.
When employed for poultry fencing or similar uses where the fabric is
supported in suitable position from posts, this form of mesh causes said fabric to
readily yield or "draw in" and sag between the posts.
In the event of a broken selvage-wire the twisted portions of the mesh-forming
wires act pivotally and offer slight resistance to the vertical strain rendering the
fabric of little use and necessitating frequent props or supports to keep it at its
proper width. The meshes in the event of a broken selvage also draw together
from the longitudinal strain.
My improvement is designed especially to overcome these objections without
materially increasing the cost of manufacture of the fabric and without the
employment of vertical stiffening wires or other means ordinarily used. The
selvage wires are connected by the mesh forming wires.
The netting comprises vertical rows of hexagonal meshes, alternating with
vertical rows of rectangular meshes.
The frames containing the twisting segments are operated in the ordinary
manner to form the hexagonal meshes, and instead of being moved from right to
left or in the opposite direction to engage with wires forming the next succeeding
row of twists the frames and twisting segments are carried together in one direction
for a determined distance.
The twist is reversed at one point for a determined distance. The reversed twist
thus formed runs diagonally of the selvage and at an angle to the twist which forms
the hexagonal mesh.
One frame is then reversed causing it and its wire and segment to move laterally
to a given position, the other frame and its segments travelling on in alignment
with the reversed twist where it meets the companion wire of an adjacent segment
and forms the longitudinal twist of the next hexagonal mesh.
This forms a row of elongated rectangular meshes, said meshes being arranged
diagonally of the fabric. Alternate rows of rectangular meshes run in opposite
directions with an interposed series of hexagonal meshes between.
It will be seen that the smooth or untwisted portion of each approximately
rectangular mesh, forms a side of the adjacent approximately hexagonal-mesh while
the reverse-twists of the rectangular meshes are parallel and form a portion of the
sides of the adjacent rectangular mesh. Such combined forms of meshes enables
the fabric to withstand the vert strain, the diagonally arranged rows of rect-
angular meshes being alternately at an angle to each other and practically forming
a truss between the selvages.

page_text: This diagonal position of the reverse-twists prevents their being readily pulled
apart as the strain thereon comes in line with the twist instead of transversely
thereof.
The twists forming the hexagonal meshes running parallel with the fabric the
strain thereon is in line with said twisted portion.
I do not confine myself to alternating the series of hexagonal and rectangular or
parallelogrammic meshes as said series of rectangular meshes may be incorporated
in the fabric at any desired distance apart, said fabric between such series of
rectangular meshes being of the ordinary hexagonal form.
Only sufficient of the diagonally arranged rectangular meshes need be employed
to impart the desired rigidity to the fabric and enable it to resist being drawn in
when the selvage becomes accidentally broken.
Twists of any desired length may be employed and may be unequal, if desired
and the form or proportion of the meshes may be varied in numerous manners by
proper manipulation of the frames and segments. Nor is it essential that the
alternating rows of meshes be formed with the ordinary or plain twist and the
reversed twist, as they may be varied as desired.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Wire Netting and the like.
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 :-
with au
As at present constructed wire-netting of this class is
woven
approximately hexagonal mesh the twisted portions of the wires forming said
meshes running parallel with the selvage and longitudinally of the fabric.
When employed for poultry fencing or similar purposes where the fabric is
supported in suitable position from posts, this form of mesh causes the said fabric
to readily yield or "draw in" and sag between the posts.
In the event of a broken selvage-wire the twisted portions of the mesh-forming
wires act pivotally and offer slight resistance to the vertical strain rendering the
fabric of little use and necessitating frequent props or supports to keep it at its
proper width. The meshes in the event of a broken selvage also draw together
from the longitudinal strain.
My improvement is designed especially to overcome these objections without
materially increasing the cost of manufacture of the fabric and without employment
of vertical stiffening wires or other means ordinarily used.
My invention is illustrated in the accompanying drawing which shows a portion
of my improved wire netting in elevation.
A B represent the selvage wires which are connected by the mesh-forming
wires fg.
As shown, the netting comprises vertical rows of hexagonal meshes as
indicated by line x, x, alternating with vertical rows of rectangular meshes as
indicated by line y, y.
The frames containing the twisting segments are operated in the ordinary,
manner to form the hexagonal meshes, h, and instead of being moved from right to
left or in the opposite direction to engage with wires forming the next succeeding
row of twists the frames and twisting segments are carried together in one direction
for a determined distance as for example between the points marked i k.
At the point j. the twist is reversed for a determined distance as k. The"

page_text: reversed twist thus formed runs diagonally of the selvage and at an angle to the
twist m which forms the hexagonal mesh.
One frame is then reversed causing it and its wire and segment to move laterally
to a given position, as p, the other frame and its segment travelling on in alignment
with the reversed twist where it meets the companion wire of an adjacent segment
and forms the longitudinal twist of the next hexagonal mesh.
This forms a row of elongated rectangular meshes t, said meshes being arranged
diagonally of the fabric. Alternate rows of rectangular meshes t, run in opposite
directions as for example on lines y, y and z, z with an interposed series of
hexagonal meshes between.
It will be seen that the smooth or untwisted portion of each approximately
rectangular mesh t, forms a side of the adjacent approximately hexagonal-mesh h,
while the reverse-twists of the rectangular meshes are parallel and form a portion
of the sides of the adjacent rectangular mesh. Such combined forms of meshes
enables the fabric to withstand the vertical strain, the diagonally arranged rows of
rectangular meshes being alternately at an angle to each other and practically
forming a truss between the selvages.
This diagonal position of the reverse-twists as at j, prevents their being readily
pulled apart as the strain thereon comes in line with the twist instead of trans-
versely thereof.
The twists, m, forming the hexagonal meshes running parallel with the fabric
the strain thereon is in line with said twisted portion.
I do not confine myself to alternating the series x, y, of hexagonal and rect-
angular or parallelogrammic meshes as said series of rectangular meshes may be
incorporated in the fabric at any desired distance apart, said fabric between such
series of rectangular meshes being of the ordinary hexagonal form.
Only sufficient of the diagonally arranged rectangular meshes need be employed
to impart the desired rigidity to the fabric and enable it to resist being drawn in
when the selvage becomes accidentally broken.
Twists of any desired length may be employed and may be unequal, if desired,
and the form or proportion of the meshes may be varied in numerous manners
by proper manipulation of the frames and segments. Nor is it essential that the
alternating rows of meshes be formed with the ordinary or plain twist and the
reversed twist, as they may be varied as desired.
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 wires twisted together to form approximately
hexagonal meshes and parallelogrammic meshes running diagonally of the fabric,
substantially as described.
2nd. A wire-netting comprising approximately hexagonal meshes with an inter-
posed series of parallelogrammic meshes with reverse twists running diagonally
of the fabric.
3rd. A wire-netting comprising approximately hexagonal meshes with interposed
series of parallelogrammic meshes arranged diagonally of the fabric, the meshes of
-ncceeding series being at an angle to those of the preceding series.
4th. The herein described netting comprising the selvage wires and the mesh-
forming wires, f, g, twisted to form the approximately hexagonal meshes h, and
alternating approximately rectangular meshes t, arranged diagonally to Baid
selvage-wires.
