We, JOHN BENJAMIN RODEN, EDGAR SAMUEL LLEWELLYN, and JOHN BURTON
HARRIS (trading as Roden, Llewellyn & Co."), of 233, Barford Street, Birming-
ham, Manufacturers, do hereby declare the nature of this invention to be as
follows;-
Hitherto the main wires arranged in the edges of wire mattresses have had to
be held in position by additional wires bound transversely, over or through the
said main wires.
The object of our invention is to construct such edges without the aid of any
auxillary wires, and to also prevent any displacement of the edges when under
pressure.
By forming the desired number of wires into strands, and then each strand
into a spiral form, and by threading each spiral strand through the others, until
we form the complete edge (according to the size and shape required) we get a
thoroughly firm edge, not capable of being squashed out of shape in use.
In building up an edging or strengthening stripe constructed according to one
form of our invention, and adapted to be attached to or introduced into a woven
wire or other mattress, we first form a foundation or basis by taking a series, say
four, of compound helices or spirals, each made up of five single helical wires
intercoiled into one another, and then intercoiling these compound spirals
together, by first connecting two of them together. then intercoiling a
third spiral with the second one, and then uniting the first spiral and
third spiral together by intercoiling with both of them, the fourth coil,
thereby forming a basis or foundation having a series of projecting spiral
edges, with each of which a further compound spiral is intercoiled, and each pair
of these last named added spirals are then coupled up at each side by having inter-
wormed into them four other compound helices, preferably each made up of a less
number of component wires, so as to leave sufficient clearance for the ready intro-
duction of the said last named coils into the spirals previously added in cases
where one coil is required to pick up two others. In this manner a cable or edging
of any size can be built up by intercoiling further coils to the projecting helices
of the spirals already added or interwoven with the basis.
The basis may be made up of any number of spirals more than one, and where
an oval, square, flat or other edging or stripe is required to be formed. the spirals
or coils are added to such previously intercoiled spirals as will produce the desired
pattern, or the said foundation or basis may be made by weaving say four com-
pound coils together in a strip, which is then folded over and the two edges and
the centre coil or coils connected together collectively by a union coil.

We, JOHN BENJAMIN RODEN, EDGAR SAMUEL LLEWELLYN, and JOHN BURTON
HARRIS, (trading as Roden Llewellyn and Company), of 233, Barford Street, Bir-
mingham, 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:-
This invention has reference to the edgings, cables and strengthening stripes
usually employed for giving strength to, and preventing the over-distension by use
of coiled or woven-wire mattresses and bed-bottoms and other woven wire fabrics
for various purposes and has for its object, to construct or make up such edges
or stripes without the employment of auxiliary wires or other means for uniting
together the component spirals or coils thereof.
In building up an edging or strengthening stripe constructed according to one
form of our invention, and adapted to be attached to or introduced into a woven
wire or other mattress, we first form a foundation or basis by taking a series, say
four, of compound helices or spirals, each made up of a suitable number of single
helical wires intercoiled into one another, and then intercoiling or interweaving
these compound spirals together, by first connecting two of them together, then
intercoiling a third spiral with the second one, and then uniting the first spiral
and third spiral together by intercoiling with both of them, the fourth coil,
thereby forming a basis or foundation having a series of projecting spiral edges,
with each of which a further compound spiral is intercoiled, and each pair of
these last named added spirals is then coupled up at each side by having inter-
wormed into them, four other compound helices, preferably each made up of a less
number of component wires, so as to admit of them being easily introduced into,
or intercoiled with, the spirals previously added in cases where one coil is required
to pick up two others. In this manner a cable or edging of any size can be built
up by intercoiling further coils to the projecting helices of the spirals already
added or interwoven with the basis.
The basis or foundation upon which an edging or cable of any desired shape and
size is made up, may be composed of any number of compound coils more than two.
Figure 1 of the accompanying drawings represents an elevation and Figure 2
a cross section of one form of foundation upon which a cable edging is built up by
intercoiling into the outstanding component spirals, other compound coils in
succession. This said foundation is made up by making a strip of fabric, composed
of three compound coils a, a, a, each made up of 7 helices, arranged alternately
with two interwoven coils b, b, each comprising a smaller number of helices such
as four.
The two outermost coils of seven a, a, are then united together by
running into them a third smaller coil c, thus forming a foundation or basis, and
by now threading or interworming into the outstanding spirals further compound
coils d, d, d, d, and e, e, e, e, each consisting of such a number of single helices
as will admit of them readily intercoiling into the spirals of the foundation and,
where necessary into one another, a cable, edging or strengthening stripe is pro-
duced of which Figure 3 is an elevation and Figure 4 a cross section.
Figure 5 represents a cross section of another form of cable made up according
to another form of our invention. In this arrangement, a series of seven com-
pound coils a, each consisting of four single helices, is taken and bundled together
and then united by intercoiling a further compound coil b, around them. To
this foundation, a further series of compound coils e, each made up preterably of a
larger number of wires, are added by weaving or coiling them into the out-
standing or projecting external parts of the coils, of the foundation. Should

page_text: a larger cable be required, or a stripe of different shape, further coils made up of
a suitable number of wires may be interwoven into such of those last added
spirals c, as will produce the desired effect.
In cases where an oval, square, flat or other edging or stripe is required to be
formed, the spiral or coils are added to such previously intercoiled spirals as will
produce the desired pattern, or the said foundation or basis may be made by
weaving say four compound coils together in a strip, which is then folded over and
the two edges and the centre coil or coils connected together collectively by a
union coil.
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:-
Making up a cable, strengthening stripe or edging for woven-wire mattresses,
bed-bottoms and the like by first forming a foundation or basis from a number of
compound coils or helices and intercoiling, interweaving or otherwise uniting
them together and then adding to or intercoiling into the outstanding or pro-
jecting parts of the foundation coils, series of other compound coils or helices, to
which, or some of which, further coils may be added in like manner in order to
make an edging or stripe of the desired size and shape, substantially as described
and set forth.
