DAVID BROOKS, JR, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE ELECTRIC CABLE CONSTRUCTION AND MAINTENANCE COMPANY, OF

ANTI-INDUCTION COMPOSBTION FOR ELECTRlC CABLES.
EPECIFICA'lZ'ION forming part of Letters Patent No. 383,096, dated May 22, 1888.
Application filcdpcoembcr 4, 1986. Serial No. 123,6!5. (No specimens.)
To aZZ whom, it may concern:
Be it known that 1, DAVID BnooKs, Jr., a citizen oftheUnited States, residing in the city and county of Philadelphia, State of Pennsylvania,have i nvented a new and useful Improvementin Anti-Induction Composition for Electric Cables, which improvement is fully set forth in the following specification.
The object of my invention is to provide a wrapping or covering for the electrical wires of a cable of such a character as to be of low induction capacity, while acting at the same time as a conductor to convey the induced cur rents to the outside of the cable, from whence r5 they are conducted to the ground by proper wires.
In carrying out my invention I take any powdered conducting material such as plumbago, carbon, or metallic dustand mix it with a gun1-such as gum copal or shellac-mud a combining niaterial such as linseed-oil and turpentine, in about equal partsthus forming a paint or gum of a conductive character fol-inducedcurrentsofelectricity. Thefibrous tapes with which the electric wires of the cable are covered are saturated with the compound thus formed, and when dry some of them are inserted within a bunch of insulated electric wires, and other tapes are wrapped around the exterior of said bunch, forming a cable. The tapes form a conductor of low inductive capacity, as well as a conductor for induced currents of great cheapness. All currents absorbed by the tapes are conveyed to the outside of the cable or to the ground by metallic 5 wires or other conducting-paths in the usual way.
I am aware that it is not new to employ a water-proofwrapping for electric wires formed of woven material saturated with a bituminous 1,0 preparation; but such mixture is a non-conductor, and would not answer the purposes intended by the saturatingcomposition herein set forth, which is to convey induced currents from the cable, and therefore must be of a con- 5 ductive character.
Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, isi 1. A composition, for the purposeset forth, 53 consisting ofplumbago, gum-copal, linseedoil, and turpentine, substantially as described.
2. A composition, for the purpose set forth, consisting of a carbonaceous gum composed of a powdered electrical conducting material, 55 guincopal, linseed-oii, and turpentine, substantiall y as described.
