FRANCIS J'. BRIDGES,
OF NEW YORK, N. Y.
IMPROVED SUBMARINE--TELEGRAPH CABLE.
Specification forming part of Letters Patent No. 243,290, dated March 22, 1859.y
To all lwhom it 'may covwem:
Be it known that I, FRANCIS J. BRIDGES, of
New York, in the county of New York and State of New York, have invented an Improvement in Conductors, (lords, 'or Gables for Electric Telegraphs; and'I dov hereby declare that the following is a. full, clear, and exact description of the principle or character which (listin-- guishes it from all other things before known,
yand Fig. 2 a crosssection through the whole.
My invention consists in an improvement in l graphs, Setforth as follows:
' The conductor is covered with a suitable electric, guttapercha being preferred for this purpose, and this is overlaid with a braided or cords, cables, or conductors for electric telc- -plaited coat of henip, dax, cotton, or wire, it
necessary, after the manner-0f a whip or eur: tain cord. The couductor,whichirnay be of one or more strands of wire, is indicated by n e, and the Prior to my improvement it has been usual I to wrap insulated conductors with material laid on helicallyybut this has "proved to be objeo. tionable from the tendency of'vsu'eh conductors to kink and twist, and bynsing a ,braided wrapping I not only obviate the tendency to kink and twist, but I obtain a conductor which has a tendency to twist.
For ordinary purposes a hempen braid .saturated with waterproof varnish is preferable;
abrasion from any cause its exterior coat may be wire-braided.
My invention' is chieliy intended for to be laid under water, and I do not confine myself to the use of any particular metal or size or number of strands oi' wires for the core of the conductor, or for its conducting elements, nor to any particular insulator or electric','nor to anyspecial material or quality or thickness or number of layers of braid, my improvement consisting. in the use of braided coat or coats for the purposes above specified. Therefore ment isl The braided or plaited coat, covering, or 'layer for conductors, cords', or cables for electrictelegrephic purposes, as hereinabove set forth.
