UNITED STATES PATENT QFFICE.
JOSEPH OLMSTED, oE"1 EovI1)ENoE, RHODE ISLAND.
IMPROVEMENT IN INSULATING TELEGRAPH-WIRES.
Specification forming part of Letters Patent No. 129,858, dated July 23, 1872.
' To all whom it may concern:
Be it known that I, JOSEPH OLMsTED, of
y the city and county of Providence, in the State of Rhode Island, have made certain new and useful Improvements in the f Method of Insulating Telegraph-Wires and I do hereby declare that the following specification is a full, clear,-and exact description thereof.
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 thepores, and then, after a subsequent scraping to remove the surplus wax, is ready for use. This method is, however, objectionable, inasmuch as it leaves the covering in a very rough and soft condition, and fails to secure perfect insulation.
In my improved method, after the wire has received its covering I dip it in parafiine or wax, after which, instead of scraping ofi' the Witnesses:
