PROVISIONAL SPECIFICATION.
Improvements in Woven-wire Spring Mattresses.
I, JOHN PICKERING, of 25 Tetlow Lane, Cheetham Hill, near Manchester,
Commission Agent, do hereby declare the nature of my said invention to be as
follows:-
This invention has for its object to so construct this class of spring mattress that
the woven wire shall accommodate itself to the body and so support every part
thereof instead of the heavier parts only and consists in arranging or mounting the
woven wire in the direction of its length cross-wise upon the wooden frame or bed-
stead instead of lengthwise as heretofore whereby the woven wire instead of being
entirely depressed by the weightier parts of the body will naturally come in contact
with every part of the body and so support and sustain the same as aforesaid, the
effect of this improved mattress being precisely similar to that of a water bed.
To further improve this class of mattress I employ a supporting device consisting
of a wire or series of wires passing centrally beneath the woven wire from head to
foot of the bedstead and secured to adjustable brackets on the wooden framework.
This wire support serves to raise or lower the centre of the mattress and keep
it taut.
Dated this 12th day of November 1891.

COMPLETE SPECIFICATION.
Improvements in Woven-wire Spring Mattresses.
I, JOHN PICKERING, of 25 Tetlow Lane, Cheetham Hill, near Manchester,
Commission Agent, do hereby declare the nature of my said 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 has for its object to so construct a woven wire spring mattress that
the woven wire shall accommodate itself to the body and so support every part
thereof instead of the heavier parts only as heretofore and consists in arranging or
mounting the woven wire in the direction of its length crosswise upon the wooden
frame or bedstead instead of lengthwise or from head to foot of the bedstead as
heretofore. In the case of what is known as a double mattress, that is a mattress
for two persons to lie upon, I employ a supporting device consisting of a wire or
series of wires passing centrally beneath the woven wire from head to foot of the
bedstead and secured to adjustable brackets on the wooden frame work which wire
or wires can be tightened up or slackened for raising or lowering the centre of the
mattress.
On the accompanying drawing
Fig. 1 is a plan view and Fig. 2 an end elevation and Fig. 3 a transverse sectional
view of a woven wire mattress constructed and arranged in accordance with my
invention.
Figs. 4 and 5 are detail views shewing the method of regulating the tension of
the supporting wires beneath the mattress.
As illustrated in Fig. 1 by the short spaced lines the longitudinal webbing of the
mattress is placed upon the wooden frame from side to side instead of from head to
foot as heretofore.
The wooden framework is constructed more or less as heretofore and may be fitted

page_text: with any suitable device such as a roller and ratchet wheel and pawl for maintaining
the tension of the woven wire.
A. A represent the supporting wires passing centrally beneath the mattress and
secured to the holder B. for supporting the centre of the mattress when used by
more than one person, the tension of which may be regulated by turning the nut C
which works against the metal bracket D. In the case of single mattresses the
supporting device is not required.
The effect of lying upon a mattress so constructed is analogous to that of lying
upon a water bed the weightier parts of the body causing the mattress to fill up and
support the lighter parts also.
Having thus 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.
1st. A woven wire spring mattress constructed and arranged substantially as
herein before described and illustrated on the accompanying drawing.
