Description
UNITED STATES PATENT QFFICE.
ISAAC I. TATOM, OF WEST POINT, GEORGIA.
IMPROVEMENT IN INSULATORS FOR TELEGRAPH-LINES.
Specification forming part of Letters Patent No. 139,436, dated May 27, 1873; application filed December 7, 1872.
To all whom it may concern:
Be it known that I, ISAAC I. TATOM, of West Point, in the county of Troup and State of Georgia, have invented a new and valuable Improvement in Telegraph-Insulators and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings makinga part of this specification, and to the letters and fig ures of reference marked thereon.
Figure 1 of the drawings is a vertical longitudinal section of my insulator. Fig. 2 is a transverse section of same.
This invention has relation to telegraph-insulators; and it consists in the novel construc tion and arrangement of the parts constituting an insulator, as hereinafter described and claimed. 7
A in the drawings represents the glass insulator or spool, made in two semi-cylindrical sections, and having a central aperture through which the Wire it passes. B designates the peg or frame to which the insulator is applied. Said frame or peg has a threaded shank, D, to be used in attaching it to a telegraph-pole or other object. The upper part of the peg is constructed with a tenonor offset, a, to the shoulder b of which is hinged the block 0. The parts a c are corrrespondingly recessed to pro vide a cylindrical cavity for the reception of the insulator, which is therein retained by the end flanges d. A shouldered latch, c, which is hinged to the upper end of the block or cov er 0, iits a mortise or slot cut in the top of the part a, and serves thus to retain the parts a 0 together.
The insulator, it will be seen, may be easily inserted in or removed from its socket when desired.
Sometimes I construct the peg without the flanges d, but use an insulator or spool having end flanges, which flanges prevent end play.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
The insulator having the frame B provided at its lower end with the threaded shank D, and its upper end having the offset a and shoulder b, hinged block 0, with the shouldered latch c, all constructed and operating in the manner shown and described.
In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
I. I. TATOM.
