I JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention to be as follows:-
This Invention has for its object a new manufacture of wire work or wire netting
suitable for poultry houses enclosures or like purposes in which new manufacture of
wire-work the meshes although all of the same dimensions are for any desired portion of
the width so crossed that at this portion (say that which is in use to be next the
ground) the openings may be so small that the smaller birds or animals cannot pass
through.
Ordinary wire-work is usually made by machinery by passing the wires through.
half pinions capable when in proper relative position of revolving in plates which are
slidden in opposite directions whilst the wires are drawn along the necessary distance.
The half pinions then come together and are then rotated by a rack and the wifes are
thereby twisted together. Then the wires are drawn along again the motion of the
plates being reversed and then the pinions are again rotated to give the next twist
and so on.
This Invention has for its object to manufacture a new kind of wire work by the
means hereinafter described whereby there is produced a new product consisting of
wire work presenting at different parts of its width different sized openings. For
this purpose a wire is passed through all of the half pinions corresponding to that
part of the width of the wire work which is to have small openings whilst through
those half pinions which correspond to the part of the width of the wire work to
have large openings I only pass a wire through say every alternate half pinion on
each sliding plate. There is given to the sliding plates a displacement, whilst the
wires travel and afterwards the pinions are rotated so that the wires which meet are
twisted and the knots in one line are formed then the plates are moved in the

page_text: other direction and the wires are traversed and then the pinions are rotated so that
the twists in the next line are formed and so on but as at one part of the width
of the wire-work the wires are passed through all the half pinions whilst they are
passed through only every alternate half pinion at the other part of the width it
will be evident that at the part of the width where the wires pass through every
half pinion although the actual meshes are the same size as in the other part the
wires are crossed so are to present at this part of the width much smaller openings
than in the other part. Thus at one operation there is made wire work with
different size openings at different parts. It is evident that wire work may be thus
made to have any part or parts of its width with the aforesaid crossings of the
wires to make small openings and that by passing the wires through other than every
alternate half pinion at the part corresponding to the part of the wire-work to be
made with large openings any desired difference in the relative sizes of the openings
in different parts of the wire work can be obtained.
The wire work is finished by the ordinary process at the edges and at the parts
where the portions with different sized openings meet.

I, JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been com-
municated to me from Abroad by Auguste Belpêche of Paris in the Republic of
France and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This Invention has for its object a new manufacture of Wire-work or wire-netting
suitable for poultry-houses, enclosures or like purposes, in which new manufacture, of
wire-work, the meshes, although all of the same dimensions, are for any desired
portion of the width so crossed, that at this portion, (say, that which is in use, to
be next the ground,) the openings may be so small that the smaller birds or animals
cannot pass through.
Ordinary wire-work is usually made by machinery by passing the wires through
half pinions, capable, when in proper relative position, of revolving in plates which
are slidden in opposite directions whilst the wires are drawn along the necessary
distance. The half pinions then come together and are then rotated by a rack and the
wires are thereby twisted together. Then the wires are drawn along again, the motion
of the plates being reversed and then the pinions are again rotated to give the next
twist and so on.

page_text: This Invention has for its object to manufacture a new kind of wire-work by the
means hereinafter described, whereby there is produced from the existing machines a
new product, consisting of wire-work presenting at different parts of its width
different-sized openings. For this purpose, a wire is passed through all of the half-
pinions, corresponding to that part of the width of the wire-work which is to have
small openings, whilst through those half-pinions which correspond to the part of the
width of the wire-work, to have large openings, I only pass a wire through, say,
every alternate half-pinion on each sliding plate. There is given to the sliding plates
a displacement, whilst the wires travel, and afterwards the pinions are rotated so that
the wires which meet are twisted and the knots in one line are formed, then the plates
are moved in the other direction and the wires are traversed and then the pinions are
rotated so that the twists in the next line are formed and so on, but as at one part of the
width of the wire-work, the wires are passed through all the half pinions, whilst they
are passed through only every alternate half pinion at the other part of the width, it
will be evident that at the part of the width where the wires pass through every half
pinion, although the actual meshes are the same size as in the other part, the wires are
crossed so as to present at this part of the width much smaller openings than in the
other part. Thus, at one operation, there is made wire-work with different-sized
openings at different parts. It is evident that wire-work may be thus made to have
any part or parts of its width with the aforesaid crossings of the wires to make small
openings, and that by passing the wires through, other than every alternate half-pinion
at the part corresponding to the part of the wire-work to be made with large openings,
any desired difference in the relative sizes of the openings in different parts of the
wirework can be obtained.
The wire-work is finished by the ordinary process at the edges, and at the parts
where the portions, with different-sized openings meet.
And in order that the said Invention.may be fully understood, I shall now proceed
more particularly to describe the same, and for that purpose shall refer to the several
figures on the annexed Sheet of drawings, the same letters of reference indicating
corresponding parts in all the figures.
Figures 1 and 2 of the accompanying drawings are diagrams, illustrating the process
of manufacturing ordinary wire-net with uniform or equal meshes, as heretofore
practised.
Figures 3 and 4 illustrate the manufacture of wire-net, according to this Invention,
and Figure 5 is an enlarged detail, shewing the structure of the meshes, thus
produced.
Referring to Figures 1 and 2 the wires are passed through half pinions as shewn the
pinions being carried by sliding pinion plates (A and B) and operated by racks in the
usual manner. In the drawing the pinions in one plate are marked with even
numbers and the pinions in the other plate with odd numbers. When the plate A is
moved in the direction of the arrow for example the plate B is moved in the direction
of the arrow the extent of the relative movements of the plates being regulated
according to the work. For example assuming the distance between the pinions
from centre to centre to be say one inch and that a wire is passed through each
pinion the wires are drawn upwards by the motion of the peg roll which draws up
inch of wire whilst the sliding pinion plates are shifted relatively to one another to
such an extent as to bring together the half pinions 1 and 2, 3 and 4, 5 and 6 etc. as
indicated iu Figure 2. The plates being now stationary the racks cause the pinions
to describe two or more revolutions according to the twist. The wires being thus
twisted together in pairs the plates are again shifted so as to bring together the half
pinions 2 and 3, 4 and 5 &c. After the racks have turned the pinions so as to twist
together the wires as before the plates return to their original position and the same
operations are repeated.

With this arrangement or construction of apparatus it is possible to make netting
with meshes double the size on the same machine, by simply threading the wire
through every alternate half pinion (1. 5. 9 &c. and 4. 8. 12 etc.) and shifting the
pinion plates twice the distance required for making the small meshes so as to bring

page_text: together the pinions 1 and 4, 5 and 8, 9 and 12 etc. and proceeding with the twisting
in the same manner as before.
Figures 3 and 4 illustrate the novel combination of the actions herein before described
whereby it is rendered possible. to manufacture a new product namely a wire net
presenting meshes of different sizes at different parts of its width without altering the
construction of the machines ordinarily employed.
A piece of net thus manufactured is represented in Figure 3 the large meshes being
on the left and the small meshes on the right the latter being produced by crossing
the wires as hereinafter explained so as to reduce the area of the openings.
With this object a wire is threaded through every pinion on the right hand or that
part of the machine where the small meshes are to be produced but on the left hand
or part where the large meshes are to be formed the wires are threaded through
every alternate pinion only. In the drawing the half pinions 3, 7 and 2, 6, 10 carry
no wire whereas every pinion on the left of the line ab carries a wire. The pinion
plates A. B are first shifted in such a manner as to bring together the half pinions
1 and 4, 5 and 8 etc. the racks are then operated so as to form the knots or twists
at m, m for example then after turning the peg roll so as to take up a length of
netting corresponding to the distance n the pinion plates are again operated so as to
bring together the half pinions 5 and 4 on the vertical line 2, 9 and 8 on the line
and so on
All the pinions are then rotated by the racks and form the twists at un
This method of proceeding produces as shown in the drawing a series of meshes all of
the same size but in which the wires are crossed at the right of the line a b so that
this portion of the fabric practically possesses the advantage of having smaller meshes
The structure of these meshes is also shown in figure 5 draws to a larger scale.
y
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed I declare that what I claim is
First As a new product of manufacture a continuous web of wire work or wire
net wherein all the meshes produced are of the same size but the wires forming the
said meshes are crossed at or part of the width in such a manner as to cause the web
to present smaller openings at this part than at the other part substantially as herein-
before described and illustrated in the accompanying drawings.
Second-The new or improved method of conducting the process of manufacture
whereby a web of wire work or net with contracted openings at a portion of its width
is produced in one operation and without altering the construction of the existing
machines substantially as hereinbefore described with reference to the accompanying
drawings.
Third The particular arrangements and combinations hereinbefore set forth whereby
the new manufacture of wire work is enabled to be carried out in practice substantially
as herein before described and illustrated in the accompanying drawings.
