Improved Metallic Fabrics for Clothing, Upholstering and other
Purposes.
1, WILLIAM GEORGE ROTHWELL, of 18, Chatsworth Avenue, Walton, near Liver-
pool, in the County of Lancaster, Master Mariner, do hereby declare the nature of
this invention to be as follows:
Fabrics constructed according to this invention are formed of metallic con-
stituents, combined or fabricated as follows.
=
In constructing a fabric according to this invention, I spin a number of metallic
helices upon suitable cores: These helices and their cores may form either the
warp or the weft of the fabric, and are united together by wefts or warps formed
of similar halices, or plain motallic wire, or their equivalent.
In some cases the helices are fabricated together without their cores.
I prefer aluminium wire for the purposes of this invention, but other metal
may be employed.
Fabrics formed as above described are applicable to many uses.
Improved Metallic Fabrics for Clothing, Upholstering and other
Purposes.
I, WILLIAM GEORGE ROTHWELL, of 18, Chatsworth Avenue, Walton, near Liver-
pool, in the County of Lancaster, Master Mariner, 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 a warp and weft fabric, woven of metallic constituents.
In constructing a fabric according to this invention, I spin a number of
metallic spiral helices upon suitable cores. In preparing these helices I wind
wire of any suitable metal on any suitable core, which core may be used to wind
the helix upon only and may then be removed, or the core may remain within
the helix and in this case the core will be metallic. The said core and wire are
not twisted together or doubled, but the wire is wound upon its core in such a
manner that the core forms the axis of the helix, and between each turn or coil

page_text: of the helix there exists a space, that is to say, the coils of the helix are so
pitched that a space exists between each coil equal (or thereabouts) to the
diameter of the wire used to form the helix. The art of spinning such helices
being well known, a description of a mode of producing them may here be dis-
pensed with.
The novel fabric according to this invention is formed by a series of the above
described helices being woven either as the warp or the weft of the fabric, in
conjunction with any suitable metallic strand or wire as the weft or the warp,
respectively; that is to say, helical warps will be woven together by a metallic
strand or wire weft, and metallic strand or wire warps will be woven by a helical
weft.
Assuming it desirable to weave the fabric with the helix as the weft, the pitch
of the helix should correspond with the number of warp wires. For instance, if
the helix possesses eighteen turns or coils to the inch, then the number of warp
wires to the inch should be thirty-six, so that a warp wire will lie between each
turn or coil of the helix on both sides of the core. Unless the warp wires corre-
spond in number to the pitch of the helix, as above specified, a streaky or openly
woven fabric is produced, but such a fabric may in some cases be desirable.
The helical constituent of my novel fabrics, when used either as the warp or
as the weft of the fabric, may possess a core or be without one, but in the latter
case a fabric of correspondingly less strength will be produced, although it will
possess greater elasticity.
Another variety of fabrics according to this invention may be composed of a
helical warp and a helical weft, the helices of the weft being of less diameter and
in most cases of more slender wire than that of the warp helicos.
In another variety of fabrics according to this invention, helical warps are
woven with wefts composed of two or more metallic strands or wires twisted
together to produce a slender cord, and as an alternative, warps of such metallic
cord are woven with helical wefts. Such metallic cord may also form the cores of
helices.
The finer varieties of my novel fabrics may be woven upon existing looms,
with or without the Jacquard motion, whilst heavier fabrics may require the loom
and shuttle to be enlarged or adapted to their manufacture.
It will be seen that according to this invention is produced what may be
termed a helical fabric, inasmuch that one or both of the elements, .e., the warp
and weft, consist of spiral helices with or without cores forming the axes of such
helices.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A warp and weft fabric wherein the warp or the weft or both warp and weft
is or are metallic spiral helices with or without cores forming the axes of such
helices, combined or fabricated substantially in the manner herein described.
