Improvements in the Manufacture and Production of Flexible Metal
Bars, Cables, or the like, suitable for use as Electric Conductors or
for other Purposes.
I, HENRY EDMUNDS, of 39 Victoria Street, in the City of Westminster, Electrical
Engineer, do hereby declare the nature of this Invention to be as follows:-
My Invention relates principally to flexible metal bars, cables or the like, com-
posed of wires or strips of copper or other metal or metals made into the form
of a rope or cable and then compressed to any desired form, usually a rectangular
form in cross section. With such bars, cables or the like as hitherto made the
wires or strips are liable to bulge outwards and lose their shape when the bar,
cable or the like is bent and it is the object of my Invention to prevent this.
According to my Invention I make the wires or strips into a rope or cable
form and thereafter or during construction I cover the said rope or cable by
a covering or by coverings of interlaced braided. or woven wires or strips,
forming a tube or tubes or jacket or jackets closely encircling the rope or
cable. The rope or cable with the interlaced braided or woven tube or jacket
or tubes or jackets around it is then compressed into the required form and the
interlaced braided or woven wire tube or jacket is, or tubes or jackets are, com-
pressed with it and takes, or take, its form and prevents or prevent the bulging
of the component wires or strips of the flexible bar or cable or the like when it
is bent. The tube or jacket or tubes or jackets or wrapping or wrappings of
interlaced braided or woven wires or strips may be entirely outside the rope or
cable or it or they may be included in the body of the rope or cable, say inside
the outer layer of strands and another further iuwards if desired in addition to
or in substitution for the outside tube or jacket. Such wrapping or wrappings
of interlaced braided or woven wires or strips may also be applied to ropes or
cables of round or other form which are not compressed.

COMPLETE SPECIFICATION:
Improvements in the Manufacture and Production of Flexible Metal
Bars, Cables, or the like, suitable for use as Electric Conductors or
for other Purposes.
I, HENRY EDMUNDS, of 39 Victoria Street, in the City of Westminster, Electrical
Engineer, do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My Invention relates principally to flexible metal bars, cables, or the like, com-
posed of wires, or strips, of copper, or other metal, or metals, made into the form
of a rope or cable, and then compressed to any desired form, usually a rectangular
form in cross section. With such bars, cables, or the like, as hitherto made, the
wires, or strips, are liable to bulge outwards and lose their shape when the bar,
cable, or the like, is bent, and it is the object of my Invention to prevent this.
According to my Invention I make the wires, or strips, into
rope, or cable
form, and thereafter, or during construction, I cover the said rope, or cable, by
a covering, or by coverings, oft interlaced, braided, or woven wires, or strips,
forming a tube, or tubes, or jacket, or jackets, closely encircling the rope, or
cable. Figure 1 of the accompanying Drawing shews in, side view a portion
of a bar, conductor, or the like, made according to my Invention and Figure 2
is a cross section thereof. a are the wires, or strips, which are made into rope, or
cable form, and b indicates the covering, or jacket, encircling the said rope,
or cable, and made of interlaced, braided, or woven wires, or strips. The rope,
or cable, with the interlaced, braided, or woven tube, or jacket, or tubes, or
jackets, around it, is then compressed into the required form and the interlaced,
braided; or woven wire tube, or jacket, is, or tubes, or jackets; or tubes, are com
pressed with it and takes, or take, its form and prevents, or prevent, the bulging of
the component wires, or strips, of the flexible bar, or cable, or the like, when it is
bent. The tube, or jacket, or tubes, or jackets, or wrapping, or wrappings, of
interlaced, braided,, or woven wires, or strips, may be entirely outside the rope,
or cable, or it, or they, may be included in the body of the rope, or cable; say inside
the outer layer of strands, and another further inwards is desired; in addition
to, or in substitution for, the outside tube, or jacket. Figure 3 shews in cross
section a bar conductor, or the like, in which some of the wires, or strips, a, of
the rope, or cable, are covered by interlaced, braided, or woven wires b, then the
remainder of the wires, or strips, 3, of the rope, or cable, are placed over these,
and finally, the interlaced, braided, or woven, wires 62, are placed over these.
Figure 4 is a cross section shewing a bar, or conductor, made of three portions
of the wires, or strips, constituting the rope, or cable, as at a, a, a³, with inter-
vening layers 6 and 62, and an external layer 3, of interlaced, braided, or woven
wires. In these arrangements the outer layer of interlaced; braided, or woven;
wires, and 3, may be omitted if desired. Such wrapping, or wrappings, of
interlaced, braided, or woven, wires, or strips, may also be applied to ropes, or
cables, of round, or other form which are not compressed.
:
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:-
1. A flexible metal bar, conductor, or the like, consisting of wires, or strips,
combined in rope, or cable form and covered, or jacketted, with interlocked,
braided, or woven wires, or strips, closely encircling the rope, or cable; substan-
tially as herein before described.
2. A flexible metal bar, conductor, or the like, made by forming wires, or strips,
into rope, or cable form, and then covering, or jacketting, this rope, or cable,
with interlocked, braided, or woven wires, or strips, closely encircling the said
rope, or cable, and then compressing the rope,, or cable, so covered, 'or jacketted, so
as to bring it to the required cross sectional form; substantially as hereinbefore
described.
or
3. A flexible bar, conductor, or the like, made with interlaced, braided,
woven, wires, or strips, included in the body of the rope, or cable, with, or without,

page_text: a covering, or jacket, of such interlaced, braided, or woven wires, or strips,
outside the rope, or cable; substantially as hereinbefore described.
