UNITED STATES WILLIAM D. KYLE, OF MILWAUKEE, WISCONSIN.

STRAIN INSULA'IOR.

Application filed December 30, 1921.

To all whom it may concern:

Be it known that I, VILLIAM D. KYLE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of IVisconsin, have invented new and useful Improvements in Strain In sulators, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The invention relates to strain insulators.

The object of the invention is to improve upon the usual stiff metal clevis and its connection w'th the bolt running through the insulator, by providing a flexible cable forn1- ing the clevis and firmly anchoring this cable in a simple and effective manner for its connection with the bolt. By this arrangement a standard size clevis may be used for all sizes of strain insulators, whereas it has been necessary, with the stiff metal clevis, to keep different sizes on hand to fit different sizes of insulators.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. l is a front eleva tion view .of a device embodying the invention, parts being shown in section; I 2 is a side elevation view thereof; Figs. 3-? and l: are vertical sectional views showin slightly modified constructions.

In the drawings the numeral 4 designates a strain insulator usually made of porcelain and having a hole 5 therein for the guy cable and a groove 6 extending around one end to opposite ends of said hole and an opening 7 extending at right angles to said hole 5 receiving the clevis bolt 8.

.=.ccording to the present invention the clevis is formed by a flexible metal cable 9 and means for operatively connecting the ends thereof to the bolt 8.

For connecting the ends of the cable 9 with the bolt 8. I preferably provide eyes 10 to which the ends of the cable are secured in each instance by casting the metal forming the eye about the coiled end 11 of the cable. The metal forming the eye is preferably cast iron or lead. here lead is used hubs 12 may be formed integral with the main portion of the eye and project into the flared ends 13 of the opening 7, as shown in Fig. 3, or the hubs 12 extend into meeting engagement, as shown in Fig. 4. These Serial No. 525,843.

eyes are made long enough to form a good bearing connector with the bolt.

IVith this construction the ends of the cable are securely embedded in the eyes and these eyes are mounted on the bolt on either side of the insulator eland drawn into engagement therewith by tightening up the nut 14: of the bolt 8. The cable clevis readily adapts itself to strain insulators of different sizes and by making this cable loop of a size to take the largest size insulator it may be used on all other sizes so that neither the manufacturer nor the user has to keep a stock of clevises of different sizes on hand, as the one standard clevis is suitable for all sizes of insulators.

I desire it to be understood that this invention is not to be limited to any specific form or arrangen'ient of parts except in so far as such limitations are specified in the claims.

IVhat I claim as my invention is:

1. In a strain insulator, the combination with the insulator, and the bolt passing therethrough, of a loop of flexible cable adapted to take insulators of different sizes, and means for securing the ends of the cable to the bolt on opposite sides of said insulator.

2. In a strain insulator, the combination with the insulator, and the bolt passing therethrough, of metal eyes fitting onto the bolt on opposite sides of the insulator, and a loop of flexible cable having its ends secured to said eyes.

3. In a strain insulator, the combination with the insulator. and a bolt passing there through, of metal eyes fitting onto the bolt on opposite sides of the insulator, and a cable loop having its ends embedded in said eyes.

t. In a strain insulator, the combination with the insulator, and a bolt passing therethrough, of metal eyes fitting onto the bolt on opposite sides of the insulator, and a cable loop having coiled ends embedded in said eyes.

5. In astrain insulator, the combination with the insulator having a clevis bolt opcning with flared ends, and a bolt passing through said opening, of metal eyes fitting onto the bolt and having extensions seated in said flared ends, and a cable loop having its ends secured to said eyes.

In testimony whereof I afiix my signature.

IVILLIAM D. KYLE.
