Improvements in Machinery for the Manufacture of Wire Netting.
I, JAMES GARTON BOWER, the Younger, of Earlham House, in the City and
County of Norwich, Managing Director of the Firm of Barnard Bishop and
Barnards, Limited, do hereby declare the nature of this invention to be as
follows:
.
This invention has reference to improvements in that kind of machinery for
the manufacture of wire netting, which forms the subject of my previous Patent
No. 4323 of the year 1892, wherein slides with half pinions spaced for different
sizes of mesh are adapted to assume relative positions; in which a half pinion
of a set of half-pinions spaced for producing one size of mesh will be opposite
to and will coincide with a half pinion of a set spaced for producing another size
of mesh so that upon then imparting a rotary movement to these two half pinions,
about their common axis for the time being, the wires of the different sets of
meshes will be united.
In such machines, according to my present invention, I adopt an arrangement
of slides with half pinions and rack for operating the pinions according to which
some of the slides which have motion imparted to them by any suitable mechanical
means, are able to be moved to some extent independently of another or ether
slides, but will be caused, during a part or parts of their travel, to actuate such
other slide or slides as I will proceed to explain more particularly with reference"
to the accompanying illustrative diagrammatic drawings which are given by
way of example and for the purpose of enabling the nature of my present inven-
tion to be more clearly understood.
Fig. 1 shows in plan an arrangement in which there are four slides A, B, C,
and D with half pinions adapted either to produce netting having the meshes a
the central portion of its width of smaller size than the meshes at the respective
sides (or top and bottom) or to produce simultaneously two separate equal or
unequal widths of wire netting each having for a part of its width (or height)
meshes of smaller size than the remainder.
Fig. 2 is a similar view to Fig. 1. but showing the slides and half pinions in
different relative positions to those shown in Fig. 1.
Fig. 3 is an end view.
In describing the arrangement I will assume that it is being for the moment
employed to produce one width of netting with three different sizes of meshes.
The slide A is provided with three sets of half pinions viz. M M M M³, and
TT TT, and M** M M M. The half pinions T in the central set are pitched
for producing the smaller meshes in the netting, whilst those M M* M** in the
two end sets are pitched at wider and corresponding centres for producing the
larger meshes in the netting.
The slides B and C are suitably connected with slide A so as to be operated
therefrom, as, for example, by a rocking lever E at each end, or the two slides B
and C may be firmly connected together as by a frame F (Figs. 2 and 3) and be

page_text: operated from the slide A by a rocking lever E at one end only. Each of the
slides B and C is provided with a set of half pinions m m m m³ and m** m m m
respectively having the same pitch as the set of half pinions M M* M** in the
slide A, which they are arranged to come opposite to. The slide D is movable
between the slides B and C and is not connected to them. It is mounted so as to
be able to slide freely in the frame F, which connects the slides B and C, when
these are firmly connected together, or on the supports on which slides B and C
are mounted to slide. The slide D is provided with a set of half pinions ttttt**
of the same pitch as the set of half pinions T in the slide A. G is a rack gearing
with the pinions; it is provided with means for reciprocating it in any suitable
manner, and is arranged to slide horizontally in the slide A.
Assuming the half pinions T t t ** to have a pitch of 1½ inches, and the
half pinions M M* M** M and m m³ m m a pitch of 24 inches; also that the
parts are in the relative positions shown in Fig. 1, and that the slide A is moving
to the right, then the action of the apparatus will be as follows:-
The half pinions M M* M** M in slide A will be moved 18 inches to the
right whilst the half pinions m m³ mm in slides B and C will be moved through
the rocking lever or levers E, 1½ inches to the left, thus bringing three of the
left hand half pinions M opposite to the half pinions m of the slide C, and the
fourth left hand pinion M opposite the half pinion m³ of slide C and the half
pinion M opposite the half pinion t*, as shown in Fig. 2; also the four half pinion T
of slide A opposite the four half pinions tttt** of slide D, and the right hand
half pinions M M M M of slide A opposite to the half pinions m m m m of
slide B.
XX
The half pinions pitched for the small mesh in slide A will have moved 1
inches to the right, but as these are pitched at 1½ inch centres, to enable them
to coincide with the half pinions in slide D, the slide D will have been moved
3 of an inch to the left. For this purpose the distance between the two end half
pinions and the adjacent ends of the slide D in which they are mounted,
the distance between each of the two inner end half pinions m³ m** and the
adjacent end of the slide B or C in which it is mounted, and the difference in
length between the slide D and the space H between the inner ends of the
slides B and C, are made such that in sliding to the left the slide B will have
moved up to D and will have pushed it the necessary distance whilst C will
have been moved away, slides B and D for the moment acting as one slide with
half pinions of different centres. In the position of the parts shown in Fig. 2
it will be seen that the half pinion M of the left hand set of half pinions will
have been brought over the half pinion and that the half pinion M of the
right hand set of half pinions will have been brought over the half pinion m
of the right hand set of half pinions in the slide B. The rack G is then caused
to rotate each pair of half pinions about its axis for the time being, the wires
passing through the pairs of juxtaposed half pinions M* * and M** m* being
twisted together to unite the larger meshes to the smaller meshes. When this
has been done, the slide A will be moved to the left and B and C to the right,
slide C moving up to slide D and pushing it the necessary distance to make the
half pinions TT TT again coincide with the half pinions t* ttt as shown in
Fig. 1, slides C and D at this time becoming practically one slide whilst slide B
will be moved away independently of 1). When the parts have thus again
assumed the relative positions shown in Fig. 1 a junction of the three sets of
meshes again made. The above described operations are repeated continuously,
the finished netting being drawn off in the usual manner.
When making two separate widths of netting each having two sizes of mesh
the operation will be similar, but the two sizes of mesh in the left hand width will
be joined in the position indicated in Fig. 1, and those in the right hand width
will be joined in the position indicated in Fig. 2.
As will be obvious slides with half pinions arranged and operating as described
can be variously modified. Thus the slide A instead of being made in one piece

page_text: as shown, may be made in two or more parts linked or otherwise connected together.
The slides B and C may be in two or more parts separately operated, or bolted
or otherwise connected together so as to act as one piece. The slide 1 may be
connected to slides B and C by links if desired, and it may be made in parts
linked together. Again, slide A may be provided with five or other number of
sets of half pinions, pitched at different centres and arranged to work
in connection with a similar number of correspondingly pitched half
pinions carried by five or other number of slides some of which
are Ol' may be connected together and be directly operated and able
to move to some extent independently of the others, but will be caused during
a part or parts of their travel to actuate such other slides in the manner herein-
before described for the single slide D. With such an arrangement I could
produce simultaneously two separate widths of netting each comprising three
different sizes of mesh at different parts of its width or height. Sometimes I
so arrange that one of two slides whose half pinious have to come opposite one
another are or may be caused to move through a greater distance than the other
of such slides.
Instead of moving each of the slides A B and C or equivalent slides to an
equal extent as herein before described with reference to the example illustrated
in the drawings, the slides may be so relatively moved that the motion say
of B relatively to A differs from that of C relatively to A and each set of half
pinions in the slide A and the corresponding oppositely arranged slide may
have a pitch different from each of the other sets so that netting having three
or more sizes of mesh can be produced.
It is to be noted that machines according to my present invention may be
variously constructed and arranged and that the number of slides employed will
depend upon circumstances.
Improvements in Machinery for the Manufacture of Wire Netting.
I, AMES GARTON BOWER, the Younger, of Earlham House, in the City and
County of Norwich, Managing Director. of the Firm of Barnard Bishop and
Barnards, Limited, 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 has reference to improvements in that kind of machinery for
the manufacture of wire netting, which forms the subject of my previous Patent
No. 4323 of the year 1892, wherein slides with half pinions spaced for different
sizes of mesh are adapted to assume relative positions, in which a half pinion
of a set of half-pinions spaced for producing one size of mesh will be opposite
to and will coincide with a half pinion of a set spaced for producing another size
of mesh so that upon then imparting a rotary movement to these two half pinions,
about their common axis for the time being, the wires of the different sets of
meshes will be united. .

page_text: In such machines, according to my present invention, I adopt an arrangement
of slides with half pinions and rack for operating the pinions according to which
some of the slides which have motion imparted to them by any suitable mechanical
means, are able to be moved to some extent independently of another or other
slides, but will be caused, during a part or parts of their travel, to actuate such
other slide or slides as I will proceed to explain more particularly with reference
to the illustrative diagrammatic drawings left with my Provisional Specification,
which are given by way of example, and for the purpose of enabling my present
invention to be clearly understood.
Fig. 1 of the said drawings shows in plan an arrangement in which there are
four slides A, B, C, and D), with half pinions adapted either to produce netting
having the meshes at the central portion of its width of smaller size than the
meshes at the respective sides (or top and bottom) or to produce simultaneously
two separate equal or unequal widths of wire netting, each having for a part of
its width (or height) meshes of smaller size than the remainder.
Fig. 2 is a similar view to Fig. 1, but showing the slides and half pinions in
different relative positions to those shown in Fig. 1.
Fig. 3 is an end view.
In describing the arrangement, I will assume that it is being for the moment
employed to produce one width of netting with three different sizes of meshes.
The slide A is provided with three sets of half pinions viz. M M M M³, and
TTTT, and ** M M M. The half pinions T in the central set are pitched
for producing the smaller meshes in the netting, whilst those M M* M** in the
two end sets are pitched at wider and corresponding centres for producing the
larger meshes in the netting.
The slides B and C are suitably connected with slide A, so as to be operated
therefrom, as, for example, by a rocking lever E at each end, or the two slides B
and C may be firmly connected together, as by a frame F (Figs. 2 and 3) and be
operated from the slide A by a rocking lever E at one end only. Each of the
slides B and C is provided with a set of half pinions m m m m² and m** m m m,
respectively, having the same pitch as the set of half pinions M M* M* in the
slide A, which they are arranged to come opposite to. The slide D is movable
between the slides B and C, and is not connected to them. It is mounted so as to
be able to slide freely in the frame F, which connects the slides B and C, when
these are firmly connected together, or on the supports on which slides B and C
are mounted to slide. The slide D) is provided with a set of half pinions t t t t **
of the same pitch as the set of half pinions T in the slide A. G is a rack gearing
with the pinions; it is provided with means for reciprocating it in any suitable
manner, and is arranged to slide horizontally in the slide A.
IX
Assuming the half pinions T to have a pitch of 12 inches, and the
half pinions M M* M** M and m m* m m a pitch of 24 inches; also that the
parts are in the relative positions shown in Fig. 1, and that the slide A is moving
to the right, then the action of the apparatus will be as follows:-
8
The half pinions M M M M in slide A will be moved 1½ inches to the
right whilst the half pinions m m* m** m in slides B and C will be moved through
the rocking lever or levers E, 1½ inches to the left, thus bringing three of the
left hand half pinions M opposite to the half pinions m of the slide C, and the
fourth left hand pinion M opposite the half pinion m³ of slide C and the half
pinion M opposite the half pinion t*, as shown in Fig. 2; also the four half pinions T
of slide A opposite the four half pinions t t t t of slide 1), and the right hand
half pinions M** M M M of slide A opposite to the half pinions m* m m m of
slide B.
The half pinions pitched for the small mesh in slide A will have moved 1
inches to the right, but as these are pitched at 12 inch centres, to enable them
to coincide with the half pinions in slide 1), the slide 1 will have been moved
3/8 of an inch to the left. For this purpose the distance between the two end half
pinions *** and the adjacent ends of the slide 1 in which they are mounted,

page_text: the distance between each of the two inner end half pinions m² m² and the
adjacent end of the slide B or C in which it is mounted, and the difference in
length between the slide 1) and the space H between the inner ends of the
slides B and C, are made such that in sliding to the left the slide B will have
moved up to 1), and will have pushed it the necessary distance, whilst C will
have been moved away, slides B and D for the moment acting as one slide, with
half pinions of different centres. In the position of the parts shown in Fig. 2,
it will be seen that the half pinion M of the left hand set of half pinions will
have been brought over the half pinion t*, and that the half pinion M of the
right hand set of half pinions will have been brought over, the half pinion m**
of the right hand set of half pinions in the slide B. The rack G is then caused
to rotate each pair of half pinions about its axis for the time being, the wires
passing through the pairs of juxtaposed half pinions M** and M** m** being
twisted together, to unite the larger meshes to the smaller meshes. When this
has been done, the slide A will be moved to the left, and B and C to the right,
slide C moving up to slide D, and pushing it the necessary distance to make the
half pinions TT TT again coincide with the half pinions t t t t, as shown in
Fig. 1, slides C and D at this time becoming practically one slide, whilst slide B
will be moved away independently of D. When the parts have thus again
assumed the relative positions shown in Fig. 1, a junction of the three sets of
meshes is again made. The above described operations are repeated continuously,
the finished netting being drawn off in the usual manner.
When making two separate widths of netting each having two sizes of mesh,
the operation will be similar, but the two sizes of mesh in the left hand width will
be joined in the position indicated in Fig. 1, and those in the right hand width
will be joined in the position indicated in Fig. 2.
.
As will be obvious, slides with half pinions arranged and operating as described
can be variously modified. Thus the slide A, instead of being made in one piece
as shown, may be made in two or more parts, linked or otherwise connected together.
The slides B and C may be in two or more parts, separately operated, or bolted
or otherwise connected together so as to act as one piece. The slide 1 may be
connected to slides B and C by links, if desired, and it may be made in parts
linked together. Again, slide A may be provided with five or other number of
sets of half pinions, pitched at different centres, and arranged to work
in connection with a similar number of correspondingly pitched half
pinions carried by five or other number of slides, some of which
are or may be connected together, and be directly operated and able
to move to some extent independently of the others, but will be caused during
a part or parts of their travel to actuate such other slides in the manner herein-
before described for the single slide D. With such an arrangement, I could
produce, simultaneously, two separate widths of netting, each comprising three
different sizes of mesh at different parts of its width or height. Sometimes I
so arrange that one of two slides whose half pinions have to come opposite one
another are or may be caused to move through a greater distance than the other
of such slides.
Instead of moving each of the slides A, B and C, or equivalent slides, to an
equal extent as hereinbefore described with reference to the example illustrated
in the drawings, the slides may be so relatively moved that the motion, say,
of B relatively to A, differs from that of C relatively to A, and each set of half
pinions in the slide A, and the corresponding oppositely arranged slide, may
have a pitch different from each of the other sets, so that netting having three
or more sizes of mesh can be produced.
It is to be noted that machines according to my present invention may be.
variously constructed and arranged and that the number of slides employed will
depend upon circumstances.
As will be evident, where it is required to produce netting having only two sizes of
mesh, with all the meshes of one size in one position of the width, and all the

page_text: meshes of the other size in one other portion of the width of the netting, one
slide may be dispensed with-it might be, slide B or slide C, the slides retained
being made of the necessary dimensions and suitably guided.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In a machine for the manufacture of wire netting an arrangement of slides
according to which a slide or slides is or are adapted to be moved through relatively
short distances by or from other slides adapted to be moved through relatively
long distances, the first named slide or slides remaining stationary for part of the
time during which the other slides are by mechanical means being moved as
set forth, so that netting may be produced having in different parts of its width
meshes of sizes differing from one another to the desired extent substantially as
described.
2. In a machine for the manufacture of wire netting the arrangement substan-
tially as hereinabove described with reference to the drawings accompanying my
Provisional Specification of slides for producing wire netting having meshes of
different sizes in different parts of its width
