PROVISIONAL SPECIFICATION.
Improvements in or appertaining to the Wire Fabric as Employed
in the Manufacture of Mattresses, Chairs, Chair and other
Seatings, Pillows, and such Articles as have a Wire Fabric
Surface.
We, EDWARD SAMUEL BOND, and GEORGE HENRY COOPER of The Crown
Works, Booth Street, Handsworth, Engineers, do hereby declare the nature of our
said invention to be as follows:-
Our invention for improvements in or relating to the wire fabric of the kind
as used in the manufacture of wire mattresses and articles as above enumerated
is intended to impart an increased amount of tension, strength and elasticity.
As at present employed after a short usage the wire fabric as applied to the
above purposes becomes elongated and of course loses its elasticity. To obviate
this is the object of our invention.
We will describe our invention as applied to one of its many purposes (viz.) 'a
woven or wire mattress, of any desired pattern or configuration formed of helical
wires.
We employ in combination with the wire fabric a coiled helical wire which may
be either closely or openly wound of a required diameter that would allow it to
pass through the interior of the helical coils forming the wire fabric at such points
as may be required for effecting our purpose either lengthwise or crosswise
or in any manner so that the coiled wire would combine or associate itself with the
fabric.
We do not confine the use of the invention to thread through the helical coils
forming the wire fabric, but it may also be employed either upon the top of or
underneath the wire fabric.

COMPLETE SPECIFICATION.
Improvements in or appertaining to the Wire Fabric as Employed
in the Manufacture of Mattresses, Chairs, Chair and other
Seatings, Pillows, and such Articles as have a Wire Fabric
Surface.
We, EDWARD SAMUEL. BOND, and GEORGE HENRY COOPER, of The Crown
Works, Booth Street, Handsworth, Engineers, do hereby declare the nature of
our said invention and in what manner the same is to be performed, to .be
particularly described and ascertained in and by the following statement:
. :
Our invention relating to wire fabric of the kind used in the manufacture of
wire mattresses, chairs, chair and other seatings, pillows, and such articles as have
a wire fabric surface. The object of our invention is to impart an increased
amount of tension strength and elasticity. And we effect this as follows:-
In combination with the wire fabric we employ a coiled helical wire either
ice

closely or openly wound, of such a diameter that it will pass through the interior
of the helical coils which form the wire fabric at such points or on such lines as
may be required, or in any manner so that the helical coils would combine or
associate itself with the fabric.
And in order that this our said invention may be better understood we will now
proceed to describe it with the aid of the accompanying sheet of drawings. The
same letters of reference denote the same parts in every figure in which they
.occur.
Fig. 1. is a plan of a piece of wire fabric made according to our invention.
Fig. 2. is a cross section of the same.
Fig. 3. is a plan of wire fabric.
Fig. 4. is a cross-section of Fig. 3.
Fig. 5. is a plan of the border of a wire fabric made according to our invention.
Fig. 6. is a cross section of the same.
Fig. 7. shows a part of a secondary helical wire or spring closely. wound..
Fig. 8. shows a similar helical wire or spring openly wound.
We will first describe that form of our invention which we prefer to use and
which we have illustrated in the drawing A. A. is the wire fabric as usually
employed in the manufacture of mattresses chairs chair seatings pillow and cushion
coverings and for similar purposes. This consists as is well known of helices of
wire so connected with each other by being turned together that they form a
species of net work as shewn in Figures 1, 3 and 5, each of these helices which
we call the primary helices is formed either of one wire, or of more wires than
one, lying closely together. In the drawing these primary helices are each formed
of two wires, each wire being denoted by a single line.
At a, a, in Figures 1, 3 and 5 this wire fabric is shewn as commonly made.
After some degree of usage, a wire fabric made thus becomes elongated and loses, in a
greater or less degree its elasticity. To prevent this loss of elasticity is the object
of our present invention.
On reference to Figures 4 and 6 which are sections of the wire fabric it will be
seen that in the interior a', a', of each primary helix is an open space extending
longitudinally through it.
Through these interior spaces we thread wire helical springs b, b, which we call
the secondary helices, these are of such external diameter that they easily pass
through the interior of the primary helices a', a¹.
In Figures 1 and 2 we show another method of applying the secondary helices.
In this method we do not thread them through the primary helices longitudinally
but we thread them through the interstices formed by the reticulations of the
primary helices as shewn at a³, a', in Figure 2. At a', a', we shew these interstices
before the secondary helices are inserted.
However the secondary helices b, b, are applied to the fabric. We seam them
to the frame, enclosing the wire fabric by any suitable and well known method.
By the means above described we give increased strength and endurance to the
wire fabric while maintaining its elasticity Figures 5 and 6 show the border of a
wire. fabric. made. according to our invention. Here more than two of the primary
helices forming the wire fabric are turned together thus forming a strong edge or
border analogous to the "selvage" of a woven fabric.
Through the interior of these primary. helices as a² we may thread the secondary
helices or we may thread a secondary helix.as 6' in the space between the primary
helices as shewn in Figure 6 the ends of these secondary helices being secured to
the frame in the same manner as the ends. of the other secondary helices b, b.
We do not confine ourselves to the application of the secondary helices in the
manner: shown in. the. drawing, that is by threading them through the primary
helices which form the wire fabric or through their, reticulations, or the spaces
between them. We may lay the secondary helices over, or under the wire fabric,
or one set of them over, and, another set of them under, and when we treat them
in this manner. we may place them either parallel with the primary helices, or at

page_text: any desired angle. The method of doing this being so obvious, we do not shew it
on our drawing.
Fig. 7 shows a piece of one of the secondary helices 6' wound as closely as
possible.
Fig. 8 shows a piece of one of the secondary helices 6 wound more openly.
By properly proportioning the diameter of the helices both primary and
secondary, and the number and diameters of the wires of which they are composed
and also the degree of closeness of the winding. We make wire fabrics according
to our invention with such a degree of strength and elasticity and endurance as
may be proper for the particular purpose intended.
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 :-
In "Improvements in or appertaining to the wire fabric as employed in the
manufacture of mattresses, chairs, chair and other seating, pillows and such
articles as have a wire fabric surface."
1st. The combination and arrangement of coiled helical wires (secondary helices)
with a wire fabric, (primary helices) for the purposes hereinbefore described and
illustrated by the drawings.
2nd. The combination and arrangement of coiled helical wires (secondary
helices) with a wire fabric (primary helices) formed from one or more wires,
and then twined together, for the purposes herein before described and illustrated
by the drawings.
3rd. The combination and arrangement of coiled helical wires (secondary
helices) with a wire fabric (primary helices) by passing through the space in the
interior, or through the reticulations, or over, or under, so as to combine, or
associate, and at any desired angle, for the purposes hereinbefore described and
illustrated.
4th. The general construction, combination and arrangement of the respective
parts forming our invention, substantially as herein before described in the fore-
going Specification and illustrated by the accompanying sheet of drawings.
