improvements in wire mattresses.
We, WILLIAM MCLAREN and HARVEY EZRA BROWN, both of Metropolitan
Works, Dockley Road, Bermondsey, London, S.E. Manufacturers, do hereby
declare the nature of this invention to be as follows:
Our invention relates to wire mattreses and our object is to produce effective
strengthening bands or strips for the purpose of supporting the edges of a wire
mattress and also the centre parts when required.
Our invention consists in a novel construction of strengthening band or strip.
We
In carrying our invention into effect according to one method we construct a
number of wire spirals formed by winding on a mandril, forcing through a spindle
containing a spiral groove, or other method. a number of parallel wires. In one
example we place twelve parallel wires together and produce a spiral spring of wide
pitch having the appearance of a spring formed from a broad band of metal.
place a number (say such as four) of spiral springs so formed alongside of each
other and unite them together by spiral wire springs screwed in or threaded between
them in such a manner as to unite the four broad springs to form one band or strip.
The four springs may be placed to form a square band or strip having two springs
to form each side, or nine springs may be fastened together to form a square band
having three springs or spring strands to form each side.
We do not limit ourselves to any particular number of wires laid together to
form one spiral spring or strand, nor yet any particular number of spiral springs or
strands so formed laid together to form a band or strip. Thus the band may
consist of three springs with two uniting springs or five springs with four uniting
springs when made in a flat strip, or five uniting springs when the general outline is
circular. Rectangular strips may also be made having six spring strands, eight,
ten or other number showing at one edge ten spring strands and on the flat, three,
four, five or more spring strands.
A characteristic feature of the invention consists in the construction of a band
or strip from a number of spiral springs formed from a series of wires united
together by single spiral springs having a less number of wires than the main
springs.
These bands or strips may be attached to the fabric of the mattresses in different
ways, either through the connecting strand of spiral wire bereinbefore described or
through the heavy outer spiral forming part of the said band or strip, but we prefer
in most cases to so arrange that the upper surface of the mattress is preserved
uniform in level.
For cheaper mattresses we arrange these bands or strips in triangular form, that
is, constructed of three spirals suitably connected together and attached to the
fabric of the mattress at one corner so that when viewed from the side two rows of
spiral springs are seen giving it a suitably massive appearance.
We may attach these bands or strips to the centre of the mattress as well as to
the edges, and may lace them to the mattress or simply place under or along the
edges of it as we may desire.

page_text: We, WILLIAM MCLAREN and HARVEY EZRA BROWN, both of Metropolitan
Works, Dockley Road, Bermondsey, London S.E. Manufacturers, 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:-
Our invention relates to wire mattresses, and our object is to produce effective
strengthening bands or strips for the purpose of supporting the edges of a wire
mattress, and also the centre parts when required.
Our invention consists in a novel construction of strengthening band or strip.
Referring to the accompanying sheet of drawings-
Figure 1 shows a spiral spring coiled from parallel wire such as we use to build
up our own strengthening band or strip.
Figure 2 shows an end view of a flat strip so built up, and Figure 3 shows a plan
of such a flat strip.
Figure 4 shows an end view of a square band or strip;
Figure 5 is an end view of a square band or strip with nine spirals;
Figure 6 shows at a, a flat band of three spirals, at b, five spirals, and at c, a
circular band of five spirals.
Figure 7 shows an end view of a flat band or strip of eight spirals attached to the
web of the mattress.
Figure 8 shows a similar flat band arranged to finish flush above the web.
Figure 9 shows a triangular band or strip applied below the web, and
Figure 10 shows a square strip similarly applied.
In carrying our invention into effect according to one method, we construct a
number of wire spirals formed by winding on a mandril, forcing through a spindle
containing a spiral groove, or other method, a number of parallel wires.
The method of forming, however, does not constitute part of the invention.
In one example we place twelve parallel wires together and produce a spiral
spring of wide pitch, having the appearance of a spring formed from a broad band
of metal. Such a spring is shown in side elevation at Figure 1. We place a
number (say such as four) of spiral springs as A A, Figure 2, so formed alongside
of each other, and unite them together by spiral wire springs B, shown in dotted
lines screwed in or threaded between them in such a manner as to unite the four
broad springs A A, to form one band or strip.
In all the modifications hereinafter described, the main springs are marked A,
and the connecting springs B. The springs B are shown in dotted lines.
Figure 3 shows such a strip in plan, with its connecting wires B in dotted lines.
The tour springs may be placed to form a square band or strip, as at A, Figure 4,
having two springs to form each side, or nine springs, as at Figure 5, may be
fastened together to form a square band having three springs or spring strands to
form each side.
We do not limit ourselves to any particular number of wires laid together to form
one spiral spring or strand, nor yet to any particular number of spiral springs or
strands so formed, laid together to form a band or strip. Thus the band may
consist of three springs with two uniting springs, as at a, Figure 6, or five springs
with four uniting springs as at b, Figure 6, when made in a flat strip, or five uniting
springs when the general outline is circular, as at c, Figure 6. Rectangular strips
may also be made having six spring strands, eight, ten, or other number showing
at one edge ten spring strands, and on the flat three, four, five, or more spring
strands.

page_text: A characteristic feature of the invention consists in the construction of a band
or strip from a number of spiral springs, as A, formed from a series of wires united
together by single spiral springs B, having a less number of wires than the main
springs.
These bands or strips may be attached to the fabric of the mattresses in different
ways, either through the connecting strand B of spiral wire, herein before described,
or through the heavy outer spiral A, forming part of the said band or strip, but we
prefer in most cases to so arrange that the upper surface of the mattress is preserved
uniform in level.
At Figure 7 the web of the mattress is shown at C, connecting to the middle of
the strengthening band or strip A, but it is preferably arranged to form a flush
upper surface as at Figure 8, where the web C, and the band A, form a level upper
surface.
For cheaper mattresses we arrange these bands or strips in triangular form, as at
Figure 9, that is, constructed of three spirals suitably connected together, and
attached to the fabric of the mattress at one corner, so that when viewed from the
side, two rows of spiral springs are seen, giving it a suitably massive appearance.
Here the web is shown at C, and the triangular band at A.
At Figure 10 we show the band as square, consisting of four wires.
We may attach these bands or strips to the centre of the mattress as well as to
the edges, and may lace them to the mattress, or simply place under or along the
edges of it, as we may desire.
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 construction of strengthening bands or strips for wire mattresses from a
number of spiral springs, each spring consisting of a series of parallel wires forming
a ribbon spiral, and connecting such spirals together by spiral springs formed from
one wire, or a less number of wires than the main springs, substantially as herein-
before described.
2. The strengthening bands or strips for supporting wire mattresses as herein-
before described and illustrated in the accompanying drawings.
