ROBERT L. BOYTER, OF LAKEVIEW, TEXAS TIE-WIRE, ron INSULATORS.

T at whom it may concern.

Be it known that I, ROBERT L. BoYrER, a citizen of the United States, residing at Lakeview, in the county of Hall and State of Texas, have invented new and usefulImprove'ments in Tie-\Vires for Insulators, of which the following is a specification.

This invention'relates to improvements in attaching devices for connecting electric current carrying wires to insulators.

In carrying out the present invention, it is" my purpose to provide a device of the class described whereby the wire may be fastened to the insulator without the necessity of employing tie wires and the like, and which may be attached to the wire and to the insulator quickly and conveniently.

.It is also my purpose to providea' device of the type set forth which will embrace the desired features of simplicity, efficiency and durability, and which may be manufactured and marketed at small cost.

Another object of my invention is the provision of ana ttaching device for fastening electric current carrying wires to insulators which will be held on the insulator by the current carrying wire, the device being so constructed as to clamp the insulator under the action of the wire'to which it is connected.

VJith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts herenafter set forth in and falling within the cope of the claim.

In the accompanying drawing; Figure 1 1s a view in side elevation of an insulator and an electric current carrying ing device removed from theinsulator.

Referring now to the drawing in detail,

1 designates an insulator constructed of glass, porcelain or other suitable material and formed with a long tudinal bore 2 through which the securing bolt is adapted to pass, and with a circumferentialgroove 3. My improved attaching device is indicated at 4 and comprises complementary sections 5, 5 each stamped from a single piece Specificationof Letters Patent.

Application filed August 28, 1916. Serial No. 117L322.

of metal formed to provide a base (ihaving one edge curved to conform to the curvature of the insulator and formed on the curved edge of the base adjacent to one end thereof s an outwardly projecting lug 7 having the inner edge formed with an overlying hook 8, Formed on the base adjacent to the oppo site end thereof is an overlying hook 9 turned in a direction reverse to the hook 8. Formed integral with the base 6 at a point behind the hooks 8 and 9 is a strap 10 twisted to a position at right angles to the base so as to fit nicely into the groove 3. The outer ends of the strap 10 on the complementary sections are formed with an outwardly projecting lug 11 and opening 12 respectively, the opening being adapted to receive the lug llwhenthe sections are assembled.

In practice, the wire is trained through the oppositely disposed hooks 8 and 9 on the respective sections of the device and bent slightly around the insulator with the thumb and forefinger so that the strap with the opening 12 will overlie the strap with the lug 11. The wire is then pulled back to normal position and the lug 11 drops into the opening 12, thereby locking the device upon the insulator. As the wire is tightened, the portionthereof within the hooks 8 and 9 tends to straighten out, thereby causing the sections to bind upon the insulator.

While I have herein shown and described the preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine ,"myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claim and without departing from the spirit of the invention.

I claim:

The combination with a supporting insulator, and an electric current carrying conductor,'of an attaching devicefor holding the conductor to the insulator embodying complementary sections each formed from a single piece of metal formed to provide a base having one section curved to conform to the curvature of the insulator, an 'outthereof and turned in a direction reverse 11o the first mentionemi hook and overlying said to receive said conductor and cooperating base, straps integral With vsaid. base memwith the interlocking straps to hold the de-' bers respectively, and each twisted to a posivice on the insulator and secure the con? 10 tion at right angles to the'base and adapted ductor to the insulator.

to fit into a groove in the insulator, the In testimony whereof I affix my signature. outer ends of said straps being formed to interlock, and said insulators being adapted I I ROBERT L. BOYTER.
