We, ISRAEL KINNEY, of 48 Brant Avenue, Brantford, in the Province of Ontario,
Canada, Machinist, and JOHN MAU of 93 Queen Street, Hamilton, same place,
Machinist, do hereby deciare 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 :-
Fabrics of wire have heretofore been made having a general appearance similar to
ours but the manner in which the fabric is made up and pressed is such that a
loose fabric is produced. The object of our invention is to so make up the fabric
that the wires thereof shall be tight, but at the same time permit more or less
flexibility of the fabric.
To this end our invention consists essentially in combining one coil of wire with
another one at a time, by first pressing or flattening down a single coil, and into
the series of small loops thus formed, we run another coil and press or flatten it
down and so on until the desired width of fabric is obtained. This makes a tight
fabric, and it cannot be made by flattening all the coils together. The loops are all
reversed from those where the coils are all flattened down together.
In order that our invention may be fully understood we will proceed to describe the
same with reference to the accompanying drawings, in which-
Fig. 1 represents the first coil of wire flattened down, and its contiguous coil in
place ready to be flattened down.
Fig. 2 represents the completed fabric.
Fig. 3 represents a fabric made after our invention, having each loop twisted.
Fig. 4 represents a fabric as in fig. 3, having a stiffening rail or strip.
Fig. 5 is a plan view of the stiffening strip.

In carrying out our invention, a coil of wire, such as a, is taken.
flattened down, producing elliptical loops b. Another coil of wire a is run through
the loops b as shown in fig. 1 and this is flattened down, also producing loops b.
This operation is repeated, until the desired width of fabric is obtained, as shown
in fig. 2. Following the course of a length of wire, all being alike, beginning at
the left hand end of the upper coil in fig. 2, it will be seen that the wire passes
under its own length, then over the connecting parts of the loops of the contiguous
flattened coil, then under the same, and then over its own length thus interlocking the
wires tightly together.
In fig. 3, we have shown a twist in the neck of each loop, made before the con-
tiguous coil is run through. In both the forms shown in figs. 2 and 3 it will be
observed, following the length of each strand or wire, that each joint or crossing made
by its own loops is the reverse of its predecessor, i.e., the wire that crossed under at
one joint, crosses over at the next joint.
In fig. 4 is shown a stiffening rail or strip of metal d, having longitudinal slots e,
as shown in fig. 5, into which the loops of one of the flattened coils are introduced
before another coil is run through said loops. This strip may also be used with the
form shown in fig. 2.
We find that many modifications can be made without departing from the spirit of
our invention. For instance, a number of coils may be pressed down in one direction,
and then a number in the reverse direction. Also, right and left hand coils may be
pressed down in the same or alternate directions.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The method of making wire fabric, which consists in flattening down a coil of
wire, and connecting another coil therewith, and then flattening it down, and so on
until the fabric is finished.
2. The method of making wire fabric, which consists in flattening down a coil of
wire, running another coil of wire through the loops produced by the flattening, and
then flattening it down, and so on until the desired width of fabric is built up as
explained.
3. A wire fabric consisting of an interlocking series of wires having loops, the
crossings of each wire at its own loop beginning from one end and in succession
being the reverse one of the other, substantially as set forth.
4. A wire fabric consisting of a series of interlocked wires having loops with
twisted necks, substantially as set forth.
5. A wire fabric consisting of a series of interlocked wires having loops, and a
stiffening strip having openings through which the loops of one of the wires are
introduced, substantially as set forth.
