CODY LYON, OF EMMETT, IDAHO.
INSULATOB FOR ELECTRIC WIRES.
have invented certain new and useful Improvements in Insulators for Electric \Vires, of which the following is a specification,
reference being had to the accompanying drawings.
My invention relates to insulators for elecarticularly to insulators of that type wherein the head of the insulator is formed with a receiving kerf and wire engaging kerfs acting to lluld the wire in' place upon the insulator.
The general object of my invention is the revision of a simple, chea ly made, readily applied, and thoroughly e ective insulator or" this type, so constructed that the wire when turned at right angles to the entrance lrerf or when the insulator is turned at right angles with relation to the wire, the wire will be held securely in position upon the insulator without the necessity of binding wires.
Uther objects will appear inthe course of the following description.
My invention is illustrated in the accom-.
panying drawings, wherein:
f Figure l is a perspective view of my improved insulator attached to the cross arm or a telegraph pole;
Fig. 2 is an end elevation partly in section;
Fig. 3 is a side elevation partly in section;
Fig. i is a horizontal sectional view taken on the plane of the kerfs l0 and 11.
Referring to these figures, 2 designates an insulator made of any suitable material such as glass, porcelain, or other non-conductorhaving a base 3 formed with oppositely disposed downwardly extending flanges 4 Specification of Letters Patent.
Application fled Augult 11, 1915. Serial No. 44,935.
Intersecting this slot 8 are the lockin slots 9 and 10. Ihese slots are cut inwar from the corners of the head on opposite sides and have a staggered relation to each other. These slots 9 and 10 overlap each other at their inner ends and also intersect the slot 8. As a consequence a wire inserted in the slot 8 and then turned at right angles to the head so as to be disposed, within both of the slots 9 and 10 will be interlocked with the head and cannot be lifted up nor moved laterally with relation to the head.
It will be obvious, of course, that instead of turning" the wire designated 11 at right angles to the kerf 8 the insulator may be turned with relation to the wire so as to bring the slot 8 at right angles to the wire 11. It will thus be seen that there is no necessity of using binding wires for holding the wire 11 to the insulator, that the wire 11 will be securely engaged with the insulator under all circumstances and can: not be detached therefrom after the wire has been stretched, and that even if the wire is slack lb will not easilyv become detached extends downward to the middle of the head.
from the insulator inasmuch as it must be turned at right angles to the ends of the slots 9 and 10 in order that it shall pass out through the slot 8.
Having thus described my invention, what I claim is: 7
An insulator for electric wires comprising a base and a head, the head. having a vertically disposed transverse entrance slot and oppositely disposed horizontal slots in stag-- gered relation to each other, the horizontal slots overlapping each other and intersecting the vertical slot, the base having later- .ally disposed flanges adapted to embrace the cross arm of a telegraph pole, the side walls of the base between said flanges being formed with vertical grooves for engagement with fastening devices.
In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.
CODY LYON.
