Description
UNITED STATES PATENT OFFICE.-
ASSIGNMENTS, TO THE WESTERN ELECTRIC MANUFACTURING COMPANY,-
OF CHICAGO, ILLINOIS.
, V IMPROVEMENT IN INSULATINGTELEGRAPH-WIRES.
Specification forming pint of Letters Patent No. 129,858, dated July 23, 1872; reissue Not 6,954, dated February 29, 1876 application filed J one 4, 1873.
DIvIsION A.
To all whom it may concern:
Be it known thatl, JOSEPH OLMSTED, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Insulating Telegraph- ,Wires, of which the following is a specification: 7
The method of insulating now in use consists in braiding over the wire a fibrous covering, after which it is dipped in wax for the purpose of filling and closing the pores, and after a subsequent scraping to remove the surplus wax it is ready for use. This method is, however, objectionable,inasmuch as it ering, and forces the para-fine or wax into the pores, and secures perfect insulation.
B so com )ressin the coverin Y the a-raf-' line or wax is forced into the pores, and the surface becomes and apnea-rs polished. 1
Wire insulated in this manner is entirely impervious to the atmosphere, of greater durability, and less cumbersome than any heretofore made.
Having thus describcdmyinvention,I claim as new and desire to secure by Letters Patent- The method of insulating telegraph-wire,
by first filling the pores of the covering, and
subsequently compressing this covering, and
thereby polishing its surface, substantially as described.
- JOSEPH OLMSTED.
