Improvements in Wire Mattresses or Fabrics, for Bedsteads, Cots,
and like Articles of Furniture.
I, ROBERT EVAN LLEWELLYN EVANS, of 53, Willows Road, in the City of
Birmingham, Book-keeper, do hereby declare the nature of this invention
to be as follows:-
This invention relates to wire mattresses for bedsteads, cots, and other articles
of furniture, and particularly to those composed of links or diamond shaped
connections with coiled springs arranged at each, or only one end of the
fabric.
According to my invention, I direct the coiled or other springs which are
connected to the end framing of the mattress by any suitable means, inwardly
towards the centre of the framing, thus a greater pressure is exerted on the
centre of the mattress than on any other portion. If desired I may use springs
of various lengths.

I, ROBERT EVAN LLEWELLYN EVANS, of 53, Willows Road, in the City of
Birmingham, Book-keeper, do hereby declare the nature of this invention
and in what manuer the same is to be performed, to be particularly described
and ascertained in and by the following statement ;-
This invention relates to wire mattresses or fabrics for bedsteads, cots, and
other articles of furniture, and particularly to those composed of links, or diamond
shaped connections with coiled springs arranged at each or only one end of the
fabric.
According to my invention, I direct (looking from the end frame-work towards
the centre of the fabric) the coiled or other tension springs which are connected
to the end framing by any suitable means, inwardly towards the centre
of the frame; or, looking at the surface from the centre of the wire
netting or link work towards the end framework, the springs are arranged
diagonally in opposite directions from the centre of each end, thus a greater

other portion.
Where a mattress is required with tension springs at one end only, this
arrangement will of course, apply to that end alone.
Figure 1 of the accompanying drawing, represents the two end parts of a
spring surface or fabric with springs arranged according to my invention, and
fitted to the framework of a bottom of a bedstead, cot, or like article. From this
it will be seen that, according to my invention, instead of the tension springs
being arranged parallel with the longitudinal members of the supporting frame
work they are (looking from the end frame-work towards the centre of the
fabric) directed inwardly towards the middle thereof. Or, looking at the surface
from the centre of the netting or linkwork towards the end frame-work, the
said tension springs are arranged diagonally in opposite directions from the
centre of each end. The effect of this arrangement, is to direct the tension from
all the springs on the middle portion of the wire netting or link work, thus
making the said middle portion, which receives the most strain in use, con-
siderably lighter and stronger, and, inasmuch that when a person is reclining on
the surface, the weight or strain is evenly distributed on, and borne by all the
tension springs, a highly elastic and comfortable surface is produced, and
moreover the durability of the fabric is greatly increased.
I wish it to be understood that the tension springs may be of any pattern or
sirength desired, also the supporting frame-work, so long that these parts
respectively permit of the springs being so arranged that a diagonally directed
strain is applied on the middle portion of the wire netting or link work. I do
not confine myself to any particular pattern or construction of link work or
netting, also, may if desired, use springs of various lengths and strengths.
The supporting framework may be of metal, wood, or other material.
The several letters of reference indicate corresponding parts in the drawing.
A are the side members of the supporting frame work, and A', the end members
thereof. B the tension springs, the wire netting or link-work, and 1 the
side wires thereof, which may be connected to the framework by any suitable
means, such as hooks (E).'
Figure 2, shows an arrangement which may be utilized when a large size
surface or mattress is required. It will be seen that in this form the tension
springs are arranged diagonally in series, and each of these series are directed
diagonally towards, and exert a tension upon any portion of the link work.
I find in practice that with spring surfaces constructed according to my
invention, the middle portion is so very strong and unsagging, that there is no
necessity whatever to raise the centre of the fabric by artificial means, such as
arching upwardly and outwardly the end supporting members of the frame-work.
As before observed, my invention applies equally to fabrics with tension springs
at one end only as to fabrics with springs at both ends.
Having now particularly described and ascertained the nature of my
invention and in what manner the same is to be performed, I declare that what
I claim is:―
1. The combination with the link work or netting of a mattress or fabric for
bedsteads, cots, and like articles of furniture, of tension springs arranged (looking
from the centre of the surface towards the end thereof) diagonally and in opposite
directions from the centre of each end, whereby a diagonally directed tension is
exerted on the middle portion of the surface, substantially described and set
forth in Figure 1.
2. The combination with one end of the link work or netting of a mattress
or fabric, for bedsteads, cots, and like articles of furniture, of tension springs
arranged (looking from the centre of the surface towards the end thereof)
diagonally in opposite directions from the middle portion of the said end, as
described.

page_text: 3. The combination with the link work or netting of a mattress or fabric for
bedsteads, cots, and like articles of furniture, of one or more series of tension
springs arranged at either one or both ends of the fabric, and directed in such a
manner as to exert a diagonal tension on one or more portions of the said
mattress or fabric, as described and set forth in Fig. 2.
