page_text: 1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention and in what manner the same is to be porformed, to be particularly
described and ascertained in and by the following statement :—
It is very desirable that the class of electric conductors which require to be
insulated, or covered, be protected with a jacket that will be tightly applied to the
conductor, and which, will entirely cover it with a sufficient body of material to afford
protection, and not be easily abraded or unravel.
This invention relates to a jacketed electric conductor the jacket of which is provided
with these properties by being made of filling threads which are parallel with the
conductor, and two or more uniting threads which are woven in and out among the
filling threads, and caused to be wound about the conductor.
In the accompanying drawing
Figure 1 is a view of the jacketed conductor constructed according to this
invention.
Figure 2 is an enlarged view thereof.
Figure 3 is a view in horizontal section upon the line x, x, of Figure 2.
Figure 4 is a view in horizontal section illustrating the jacket as having an exterior
covering of waterproof material.
Referring to the drawings, a represents the conductor, the filling threads or
yarns, c. c the uniting woof threads or yarns, which are tightly wound around and
about the conductor, and interwoven with the longitudinal threads or yarns b, in
parallel courses or lines, the thread b, passing over the longitudinal threads b, while
the thread c passes under the same threads upon one complete circuit of the
jacket.
I am aware that electric conductors have been covered with a woven jacket having
longitudinal threads or yarns, and one connecting woof thread, but such jackets are
quite easily worn by abrasion, and, if the woof thread is severed, very easily unravels.

But with the present construction the severing of one or both the woof threads will
not permit or enable the jacket to be unravelled more than a course or two.
interweaving and interlocking of the top strands c, c¹ with the longitudinal strands, as
above specified, preventing the ravelling of either.
There may be interposed between the conductor and the jacket a film or layer of
insulating material d, as represented in Figure 3, and the jacket may be covered by
an exterior waterproof coating e (see Figure 4).
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent 1 declare that what I claim is :-
First. An electric conductor consisting of a wire covered with a single ply jacket
composed of a single set of longitudinal yarns or warps and two uniting woof or
weft throads or yarns e c' which are both tightly wound around the said wire and
interwoven with all of the said warps in parallel courses or lines, said weft threads
being alternated with the said warp threads so that in the same course the thread c is
beneath or inside of a warp thread when a thread c' is above or outside of the same
warp thread, and vice versa, substantially as set forth.
Second. An electric conductor consisting of a wire having an insulating layer or
coating and a single ply tightly woven jacket or covering composed of a single sot
of longitudinal yarns or warps 6 and two or more wefts interwoven with all the said
warps and extending around the conductor in parallel courses and passing alternately
over and under the said warps, substantially as set forth.
Third. An electric conductor consisting of a wire having a tightly woven single
ply jacket composed of a single set of longitudinal warps band two or more wofts
each of which is interwoven with all of the said warps and passing alternately over
and under the same, said jacket having a waterproof coating e, substantially as set
forth.
Fourth. An electric conductor consisting of a wire having an insulating layer or
coating d and a single ply, lightly woven jacket composed of a single set of warp
threads and two or more weft threads each of which is interwoven with all of the
said warp threads, and said jacket having a waterproof coating e, substantially as sot
forth.
