Improvements in the Manufacture of Cords, Ropes, and Twines.
I, WALTER H. Avis, of Horseheads, County of Chemung, State of New York,
United States of America, Manufacturer, 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:-
My invention relates to the manufacture of cords, ropes and twines.
The object of my invention is to produce a cord, rope or twine having wires
embedded therein, which shall have all the pliability of a fibrous cord, but not
its, elasticity, which shall be much stronger than a fibious cord or twine, and
cheaper in construction, in which the wire cores are not weakened and disrupted
by twisting and are practically insulated, and rust and deterioration of the same
prevented by their strong torsional covering of fibre, and which article when com-
pleted will have the appearance of a braided cord, rope or twine.
My invention consists of a cord, rope or twine made of single strands formed
of a number of threads or yarns of fibrous material compactly twisted together
on an untwisted wire, the completed cord having a core composed of several of
such single strands, twisted on each other, and finally an outer covering for said
core consisting of a number of doubled single strands cabled over said core, as
illustrated in the accompanying drawing, and as hereinafter described and
claimed
The accompanying drawing is a perspective view of a portion of a cord held
vertically and in which the upper part is unwound to show the separate strands,
central core of strands, and the wire core of each strand. A indicates that por-
tion of my invention in which the article as a whole, is complete, showing in
appearance the completed article as a braided cord
B is a single strand composed of a separate series of threads or yarns c, twisted
on each other and also twisted most compactly around a single straight, or un-
twisted wire core, e. Dis the core of the completed cord, composed of several
of said single strands, three being shown in the drawings, twisted together;
and around this core are cabled other strands F. The strands F are formed by
twisting two of the single strands B together in opposite directions. The number
of the yarns, core strands, and outer strands, may be varied without departing
from the principle of my invention.
Having now particularly described and ascertained the nature of this said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
-
A combined fibrous and wire-twisted and cabled cord. twine or rope, consist-
ing of single strands formed of threads or yarns of fibrous material, and a single
untwisted wire around which said threads are twisted, additional double strands
consisting of the former single wired strands twisted together, a core for the com-

and an outer covering for said core consisting of a number of said double strands
cabled on said core, substantially as described.
Dated this 6th day of February 1899.
