HOSEA. XV. LIBBEY, OF BOSTON, llIASSOHUSETTS.
COMPOUND ELECTRIC'CABLE.
SPECIFICATION forming part of Letters Patent No. 342,523, dated .May 25, 1886.
Application liled June 22, 1885.
To all 107mm zit may concern-.-
i'e it known that I, Hosen XV. LIBBEY, a citizen ot' the United States, residing at Boston, in the county of Su tt'ollr and State of Massachusetts, have invented a new and useful lmprovementin OompoundElectric Cables, of which the following is a specification.
The object of my invention is to utilize any number oeleetric currents passing simultaneously th rough a wire for telegraphieand telephonie purposes.
section and outside view of the same.
A is a central iron core7 surrounding which is a covering or casing of some suitable noncondueting material, B. Surrounding thelatter is a covering or coating of copper, O, and
The above is to be surrounded or eovaround this another covering of non-conducting material, B. Surrounding all these are alternate coverings of copper and non-conducting material, as many may be desired. Over the outermost covering or easing is an outside covering` ot' Zinc, D.
By means of the above-described combination l am enabled to transmit au independent current through the iron core and through each separate metallic easingoreovering, thus producing or transmitting a multiplicity of currents through one wire.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
An iron core surrounded by a non-conducting material, and then a coating ot'eopper,and then a non-conducting material, and so on to any desired number of alternate copper coatings and non-conducting materials, the whole covered with a coating or" zinc to resist elementary action and act as an assistant in retaining the electric current.
In testimony whereofl have signed my name to this specification in the presence of two suhscribing witnesses.
HOSEA W'. LIBBEY.
