PROVISIONAL SPECIFICATION.
Improved Apparatus for Making Wire Netting.
I, WILLIAM ALFRED PHILLIPS, of 85, Gracechurch Street, London, in the County
of Middlesex, Electrical Engineer do hereby declare the nature of this invention to be
as follows:-
The first part of this invention has reference to prior Letters Patent granted to
William Filmer No. 9188 of 1894. In the specification referred to a comb marked B
is employed for the purpose of forming a loop or eyelet in the wire. The teeth of said
comb were then made at right angles to the bar of the comb, but in practice I have
found that when the teeth of the comb are at right angles to the bar, that the
loop or eyelet is not made on the same plane as the netting, but at about right
angles to the mesh. The loop or eyelet thus formed is not desirable. According
to my invention I make the teeth of the comb, not at right angles with the bar,
but such teeth are bent or made at an angle, say, leaning towards the left or right,
by which means the loops are made on the same plane as the wire mesh.
In machinery for making wire mesh, there is employed a pinion with top and
bottom collars, and they are made in halves with vertical holes passing through
them to receive the wire. These pinions have a constant right- and lefthanded
motion imparted to them for giving the necessary twist to the mesh of the wire.
In constructing these pinions according to my invention, I place a collar at each
end of the pinion, such collars corresponding to each other in every respect so that
when the outlet ends of the holes become worn or elongated, the pinion may be
reversed so as to present undamaged holes for the outlet of the wire.

Improved Apparatus for Making Wire Netting.
I, WILLIAM ALFRED PHILLIPS, of 85, Gracechurch Street, London, in the County
of Middlesex, Electrical Engineer, 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 :-
The first part of this invention has reference to prior Letters Patent granted to
William Filmer, No. 9188 of 1894. In the specification referred to, a comb,
marked B, is employed for the purpose of forming a loop or eyelet in the wire.
The teeth of said comb were then made at right angles to the bar of the comb,
but in practice I have found that with the teeth at right angles to the bar, the
loops or eyelets are not made on the same plane as the netting, but at about right
angles thereto. The loops or eyelets thus formed are not desirable.

page_text: According to my invention I make the teeth of the comb, not at right angles
with the bar, but bent or at an angle-say, leaning towards the left or right, by
which means the loops are made on the same plane as the wire mesh.
The second part of my said invention relates to the pinions by which the wires
are twisted together to form the mesh, these pinions having top and botton collars
to support them in their bearings in two reciprocatory tables or bars and being made
in halves with vertical holes or eyelets passing through each half pinion to receive
the wires. The said pinions or half pinions are not reversible and when the outlet
ends of the guide holes become worn or elongated by the friction thereon of the
wires, they have to be discarded and new ones substituted.
My invention consists in forming at each end of the pinions or half pinions collars
or enlarged ends which correspond to each other in every respect, so that when the
outlet ends of the holes become worn, the pinions or half pinions can be reversed
and the undamaged ends of the holes presented, whereby the life of said pinions is
doubled.
In order that my said invention may be more fully understood reference is
hereafter had to the annexed drawings forming a part of this specification, in
which:-
Fig. 1 is plan view of a portion of the mesh and loop forming mechanism of a
wire netting machine having my improved comb or teeth applied.
Fig. 2 is elevation of the divided or split twisting pinion constructed according to
the second part of my invention; and
Fig. 3 is transverse section of said split twisting pinion.
Referring, firstly, to Fig. 1, letters a, a', represent the two ordinary reciprocatory
tables or bars, and b, b, the two sets of twisters or half pinions which are journalled
respectively in half circular bearings in the opposing or meeting sides of such tables
and are carried to right and left alternately by the latter to pair each half pinion
first with one neighbouring pinion and then with the other, the said parts being
arranged and operated in the ordinary manner for weaving wire netting.
Resting on the table a is a comb or bar e which is provided on the side nearest the
balf pinions or twisters b, 61 with bent fingers or teeth d which are passed through
transverse openings in the comb c and secured thereto by nuts e. In order to prevent
said teeth from turning round or moving out of a horizontal plane, I provide same
with square shoulders or flats adapted to engage with a rib or corresponding flat
surface c on the inner edge of the comb. The said teeth or fingers may be made
integral with the comb, or with a plate, which is adapted to be secured thereto, but in
such case the whole or a section of the teeth would have to be removed in the
event of a tooth getting damaged.
The ends or projecting portions of the teeth d are bent or formed at an angle to the
comb, or to the line of centres of the split pinions b, 61, either to the right hand, or to
the left, as shewn, the angle being such that when the said teeth are inserted between
the wires, and the second half of the twist is put on said wires, the loops formed
thereby will be in the same plane as the netting or meshes and, consequently, will not
necessitate the employment of labour for the purpose of flattening or straightening the
loops after the netting has left the machine, an advantage which is of considerable
importance. The teeth may be round or of other suitable shape to form round or
other shaped loops.
The comb c is actuated by a slide g arranged parallel with said comb and adapted to
be moved backwards and forwards longitudinally over the surface of table a by lever
and connecting rod from a cam on the driving end of the machine.. The said
slide carries a number of friction pulleys or bowls h (one only being shewn)
each of which, when the slide is forced endwise to the right bears against one end
of a lever i, pivotted on stud i fixed to table a and secured at the opposite end to the
comb c, and turns it about its centre to the extent denoted by dotted lines, thereby
carrying the bar or combo forwards and laterally, or in a diagonal or angular direction
towards the twisters or half pinions b, 61, that is to say, from the position shewn in
full line to that shewn in dotted line whereby the bent or angular teeth or fingers d

page_text: move slantwise over the centres of the half pinions and pass between the untwisted
wires & close up to the twisted portion, as is illustrated in Fig. 2, in which position
they remain while the pinions are rotated in the contrary direction to put the opposite
or left hand twist on the wires, as shewn at Fig. 3. When this has been accomplished
the slide is drawn back to the left to its normal position, whereupon the comb is
immediately drawn back to its normal position, clear of the pinions b, b¹, or wires
threaded therethrough, by means of the strong spiral springs attached at one end to
each lever and at the opposite ends to studs fixed to the table a.
The action of the parts for the right and left hand twisting together of the wires
to make the sides of the meshes, is well known and need not, therefore, be described.
My improvements in the twisters or half pinions for wire netting machines, consist
in constructing the lower half of the twister or pinion exactly like the upper half in
all respects, that is to say, with collars or heads 6 of equal depth at both ends thereof
and the necks b to fit either the upper or lower bearings in the tables a, a¹.
This construction of twisters or half pinions enables them to be reversed when one
end of the holes or guides becomes worn or elongated by the friction of the wires
thereon, whereby the life of each half pinion is doubled and considerable cost in
renewals saved.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In wire knitting machines, the application and employment of teeth, or a
comb, which, or the teeth of which, are bent, formed or arranged at an angle, or incline
towards the line of centres of the twisters or half pinions in the manner and for
the purposes substantially as herein shewn and described.
Secondly. In wire netting machines, the application and employment of reversible
twisters or half pinions constructed with one end the exact counterpart of the opposite
end, substantially as herein described and for the purpose specified.
