Improvements in Elastic Metallic Mattresses, Couch and like Bottoms.
We, WILLIAM ROBBINS, Mattress Mechanic, of 54, Bolingbroke Street, Heaton,
and JOHN DUNCAN HODGSON, Hardware Factor, of 32, Dean Street, both in the
City and County of Newcastle on Tyne, do hereby declare the nature of this
invention to be as follows:-
This invention relates to elastic metallic fabrics, commonly known as spring
mattresses and bottoms, that are used to form the bases of beds, cots, couches,
chairs and so forth.
In the general construction, parallel or nearly parallel, chains, woven wire
strands or the like are employed in conjunction with springs wholly or in part
connecting the mattress or bottom to the framing and to stretch the fabric for
procuring the requisite tension, various devices are applied, such as bars and
screws, which, however, are very inconvenient and the object of our invention
is to effect this purpose in a simple but effectual manner.
To this end we unite the chains, wires or their equivalents at suitable points
by connectors or attaching pieces so that a series of polygonal or other shaped
figures result.
According to one way of carrying our improvements into practice, we connect
the adjacent chains or wires transversely at convenient points in reciprocal
succession by links or hooks whereby a series of polygonal shaped spaces are
formed, those of one row, alternating with those of the next, thus straining the
fabric to obtain the necessary tension in the mattress or bottom.
Our invention is applicable to mattresses and bottoms of any shape, rectangular
or circular, and the connectors or attaching pieces may be of various dimensions
or adapted to produce multiform figures in the fabric while they may also be
arranged to be readily displaced and replaced by others, or have their lengths
varied by a right and left hand screw, a wedge or wedges or otherwise, to provide
for relaxation during use, for example.
By the herein described method and means it will be seen that our object is
accomplished efficiently and simply without the aid of the screws, clamps and
like clumsy appliances hitherto used.

page_text: City and County of Newcastle on Tyne, 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 elastic metallic fabrics, commonly known as spring
mattresses and bottoms, that are used to form the bases of beds, cots, couches,
chairs and so forth.
In a general construction, parallel or near-parallel, chains, woven wire
strands or the like are employed in conjunction with springs wholly or in part
connecting the mattress or bottom to the framing and to stretch the fabric for
procuring the requisite tension, various devices are applied, such as bars and
screws, which, however are very inconvenient and the object of our invention
is to effect this purpose in a simple but effectual manner.
To this end we unite the chains, wires or their equivalents at suitable points
by connectors or attaching pieces so that a series of polygonal shaped figures
result.
In the accompanying drawings, to which we will refer in the following des-
cription, a portion of a mattress or bottom embodying our invention is repre-
sented, Figs. 1 and 2 being plans and Fig. 3 a transverse section on the line XX
in Fig. 2.
A are chains, wires, woven wire strands or the like arranged as usual to com-
pose the mattress or bottom in conjunction with springs and a frame.
The application of our improvements to chains is exemplified in Fig. 1 and
to single wires in Figs. 2 and 3 from which the applications to the equivalents
.thereof, whether used in conjunction with separate springs or not, will be readily
understood.
According to our invention we connect the adjacent wires, chains or strands A
transversely at convenient points in reciprocal succession by links or hooks B
as shown, whereby a series of polygonal shaped spaces C are formed, those of
one row alternating with those of the next, as illustrated in Figs. 1 and 2; thus
straining the fabric to obtain the necessary tension or tautness in the mattress
or bottom.
As will be obvious, the connectors or attaching pieces B may be displaced
and replaced by shorter ones so as to provide for relaxation in the mattress
during use.
By the herein described method and means it will be seen that our object is
. accomplished efficiently and simply without the aid of the screws, clamps and
like clumsy appliances hitherto used.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is :-
-
1-In elastic metallic mattresses, couch and like bottoms, uniting the chains,
wires or their equivalents at suitable points by connectors or attaching pieces,
substantially as and for the purpose described."
2-The improved construction and arrangement of elastic metallic mattresses,
couch and like bottoms, substantially as herein described in reference to, and
shown in the accompanying drawings.
