IMPROVEMENT IN \NSULATING TELEGRAPH-WIRES.
Specification forming part of Letters Patent No. 129,858, dated July 23, 1872; reissue No. 6,955, dated February 29, 1876; application filed December 22, 1875.
DIVISION B.
suitable machine, which compresses the covering, and forces the parafline or wax into the pores, and secures perfect insulation. By so compressing the covering the paraffine or wax is forced into the pores, and the surface becomes and appears polished.
Wire insulated in this manner is entirely To all whom it may concern:
Be it known that 1,;Iosarn OLMSTED, of the city and'county of-Irovidence, and State of Rhode Island, have invented a new and useful Improvement in Insulating Telegraph Wires, 0t which the following is a specification:
The method of insulating now in use consists in braiding over the wires a fibrous coverin g, after which it is dipped in wax, for the purpose of filling and closing its pores, and, after a subsequent scraping to remove the surplus wax, it is ready for use. [his method is, however, objectionable, inasmuch as it leaves the covering in a very rough and soft condi tion, and fails to secure pe 'ect insulation.
In my improved method, after the wire has received its coating I dip it in parai'fine or wax, after which, instead of scraping off vthe surplus coating, I pass the whole through a bility, and'less cumbersome than any heretofore made.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- An insulated telegraph-wire the covering of which has its pores' filled and its surface polished, substantially as described.
