PROVISIONAL SPECIFICATION.
Improvements in Woven Wire Mattresses and similar Spring
Fabrics.
We, GEORGE WILLIAM FOX, of 53 Princess Street, Manchester in the County
of Lancaster, Solicitor, and JOHN LAROUX HULME, of. 2 and 4 London Road,
Manchester, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to woven wire mattresses and similar spring fabrics and
its object is to impart additional strength to the fabrics enabling them better to
resist the tendency to stretch in use without adding materially to their weight and
cost.
For the purpose of our invention we insert in the fabrics additional strands of
thick wire the spirals of which have a larger diameter than those of the ordinary
strands. These additional strands are inserted in the fabrics in such positions as
may be desirable and as may be determined by the use for which the fabric is
intended and by its dimensions, but in all cases we prefer to arrange at least one of
the additional strands at or near each selvedge.
Each of the additional strands may consist of a single wire or of two or more
wires coiled together as in the case of the ordinary strands, and their spirals may
be of any pitch which will mesh with the spirals of the ordinary strands. They
are constructed of tempered steel wire so that in effect they are strong spiral
springs which add to the strength and resiliency of the fabric, and are, as
herein before described, additional to and not in substitution for any of the ordinary
strands.

COMPLETE SPECIFICATION.
Improvements in Woven Wire Mattresses and similar Spring
Fabrics.
We, GEORGE WILLIAM FOX, of 53 Princess Street, Manchester in the County
of Lancaster, Solicitor, and JOHN LAROUX HULME, of 2 and 4 London Road,
Manchester, Manager, 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 relates to woven wire mattresses and similar spring fabrics, and
its object is to impart additional strength to the fabrics enabling them better to
resist the tendency to stretch in use without adding materially to their weight and
cost.
For the purpose of our invention, we insert in the fabric, additional strands of
thick wire the spirals of which have a larger diameter than those of the ordinary
strands. These additional strands are inserted in the fabrics in such positions as
may be desirable and as may be determined by the use for which the fabric is
intended and by its dimensions, but in all cases we prefer to arrange at least one of
the additional strands at or near each selvedge.
Each of the additional strands may consist of a single wire or of two or
more wires coiled together as in the case of the ordinary strands, and their
spirals may be of any pitch which will mesh with the spirals of the ordinary
ID 7

page_text: strands. They are constructed of tempered steel wire so that in effect they are
strong spiral springs which add to the strength and resiliency of the fabric, and are,
as hereinbefore described, additional to and not in substitution for any of the
ordinary strands.
We will more particularly describe our said invention with reference to the
accompanying drawings in which—
Figure is a partial plan of a mattress or piece of spring fabric constructed
according to our invention.
Figure 2 illustrates a modification of Figure 1.
Figure 3 is a partial section drawn on an enlarged scale through one of our
additional strands.
Figure 4 is a plan of Figure 3.
Figure 5 is a modification of the section shewn by Figure 3.
Figure 6 is a section also drawn to an enlarged scale of the selvedge of the
mattress or fabric, and
Figure 7 is a plan of Figure 6.
A represents the ordinary spiral strands of the fabric which may be single or
multiple as in the ordinary construction. B is the additional strand of larger
diameter and thick tempered steel wire, which may also be single as shewn by the
drawings or multiple.
The number and dimensions of these additional strands must in all cases be
governed by the circumstances in each case, but for ordinary narrow mattresses,
the relative dimensions of wire and diameter of spiral illustrated by Figures 3, 4, 5,
and 6, may be employed, and one be used at each selvedge. For wider mattresses,
there may be one at each selvedge and one at the middle as shewn by Figure 1.
For the widest mattresses six may be used as shewn by Figure 2, or even a greater
number.
In the case of the intermediate additional thick strands, that strand, or those
strands which are within the thick strand as shewn by Figure 3, may if desired, be
omitted, as shewn by Figure 5.
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 woven wire mattresses and similar spring fabrics, an additional strand or
additional strands of comparatively thick tempered steel wire of larger diameter
than the ordinary strands, arranged substantially as and for the purpose herein-
before described and as illustrated by the accompanying drawings.
