PROVISIONAL SPECIFICATION.
Improvements in Woven Wire Mattresses and other like Articles.
I, ANDREW RATHBONE, of the Firth Company, Friar's Green Mill, Warrington
in the County of Lancaster, Mattress Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to woven wire mattresses and other like articles manu-
factured from interlaced coiled wires, and its object is to give greater strength to
the articles particularly at the selvedges, and in the case of mattresses and other
broad fabrics, it may be between the selvedges also.
According to my improvements I form the selvedges or such part or parts as
require to be strengthened, of two or more layers of coiled wires so intermeshed
that each coil or spiral meshes with the spiral on each side and above and below it.
Each of the coils may be single, but I prefer to employ multiple coils.
By this means a very firm but flexible and strong part is secured which greatly
adds to the strength and durability of the mattress or other article.

COMPLETE SPECIFICATION.
Improvements in Woven Wire Mattresses and other like Articles.
I, ANDREW RATHBONE, of the Firth Company, Friar's Green Mills, Warrington
in the County of Lancaster, Mattress Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to performed, to be particularly
described and ascertained in and by the following statement :-—
This invention relates to woven wire mattresses and other like articles manu-
factured from intermeshed spiral wire strands, and its object is to give greater
strength to the articles, particularly at the selvedges, and in the case of mattresses
and other broad fabrics, it may be between the selvedges or edges also.
According to my improvements, I form the selvedges edges or such part or parts
as may require to be strengthened, of two or more layers of the spiral wire strands
so intermeshed that each turn of each spiral in the strengthened part, engages with
a turn of the spiral strand next to it above, below, and on either side.
The accompanying drawings illustrate in what manner my invention may be
carried into practical effect.
In this drawing, which represents a partial transverse section across a mattress,
only two layers are shewn in the strengthened parts, and this number will generally
be found to be sufficient, especially when each spiral strand is formed of two or more
wires, but I may use more than two layers including the layer which forms a local
part of the fabric. Also, I have shewn the added layer as consisting of five spiral
strands, but a larger or smaller number may be used according to the nature of the
fabric, five being selected as a suitable number for an ordinary mattress.
A Aare the strengthened edges and B a strengthened central part, this part
being parallel with the edges. In each case the strengthened part consists of an
added layer, making the part consist of two layers of the spiral wire strands which
are formed in the usual well understood manner. As shewn in the drawing, each
turn of each of the added spiral strands engages with a turn of each of the adjoining
spiral strands on either side, above or below. This intimate connection of all the

page_text: strands ensures their mutual support and compels each one to take its just share of
all the strains to which that part of the fabric is subjected.
Each of the spiral wire strands may consist of a single wire, but I generally
prefer to employ two or more wires in each strand, as is at present usual near the
edges of such fabrics.
By means of the added and closely connected layer or layers of spiral strands as
hereinbefore described, I secure great firmness flexibility and strength, and increased
durability for the whole fabric.
I am aware that the selvedges of woven wire mattresses have been attempted to
he strengthened by turning over the edges of the fabric and forming a kind of hem, and
that other parts of the fabrics have also been attempted to be strengthened by doubling
and folding the fabric locally, but in such cases no attempt has been made to connect
all the turns of the adjacent coils, and the strands consequently have not mutually
supported each other. I therefore desire it to be understood that I do not claim
the mere addition of a layer of spiral strands, or a local thickening of the fabric,
except when each turn of the added spiral strands engages with other turns in the
adjacent strands as herein described.
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 :-
In woven wire mattresses and other like articles, strengthened parts consisting of
an added layer or layers of spiral strands each of which has all its turns engaged
with turns of the neighbouring spiral strands, substantially as hereinbefore described
and as illustrated by the accompanying drawings.
