JOHN C. KORTIOK, OF SAN FRANCISCO, CALIFORNIA.

TOOL FOR ATTACI-IING AERIAL CABLE-HANGERS TO THEIR SUPPORTING-WIRES.

Specification of Letters Patent.

Application led November 25, 1912.

Patented Sept. 9,1913.

Serial No. 733,364.

To all whom t may concern:

Be it known that I, JOHN C. KORTIOK, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Tools for Attaching Aerial Cable-Hangers to Their Supporting-Vires, of which the following is a specification.

The hereinafter described invention relates to an improvement in tools particularly adapted for attaching aerial cable hangers to their supporting wires.

My invention will first be described and then pointed out in the claim.

To more fully comprehend the invention reference should be had to the accompanying drawings, wherein- Figure 1 is a View in elevation of my invention with the clamping jaws in closed position. Fig. 2 is a view similar to Fig. 1, but disclosing the jaws in open position. Fig. 3 is a side elevation of Fig. 1. Fig. 4 is a top plan View of Fig. 1 disclosing the elongated clamping aws.

Referring more particularly to the drawings, t-he reference numeral 1 designates a pair of operating handles of any suitable length, provided at one end with the enlarged heads 2, formed on their inner edges with lugs 3 and 4, adapted to overlap and provided in their surface with alined openings through which extend suitable rivets 5, which constitute a pivotal point for said handles, and below said pivotal point the handles are provided with straight meeting edges or stop shoulders 6 which contact when the handles are in their innermost position. The heads 2 are each provided on their outer edges with suitable ears 7 formed with openings therein, and the centers of said openings are parallel with the alined openings through which the rivet 5 extends.

Pivotally connected to the ears 7 by the rivets 8 are the lower ends of clamping members, bifurcated as at 9, forming arms 10, and the arms being positioned one on each side of the ears 7. The arms 10 are connected adjacent to their upper ends by a bridge plate 11, seated in the upper portions of the bifurcations 9, and said plate is pivotally connected to each arm by a rivet 12.

The extreme upper ends of the arms 10 are provided wit-h laterally extending head portions 18, in the opposing faces 14 of which are formed semi-circular depressions 15 ingrcable, the bent end of the hanger which projects upwardly from the aerial cable is hooked by hand over the supporting cable. Then the operator holding the tool above the supporting cable, with the clamping jaws thereof open, adjusts the same over the hanger with the hanger seated in the semicircular depressions 15, and draws the handles thereof together, which action will i force the pivotal point formed by the rivet 5 upwardly, and will force the lower end of the arms 10 outwardly, this action through the medium of the bridge plate 11 will force the opposing faces 14 of the head portions 13 toward each other until such time as the stop shoulders 6 of the heads 2 Contact with each other, the contacting of the stop shoulders limits the movement of the heads 10 toward each other and in doing so provides an opening or space 14 between the faces 14 thereof and through said opening the end of the hanger is permitted to extend while the other portion thereof is tightly clamped about the supporting cable. Y

By employing a tool constructed as above described, having a compound lever joint, it will be apparent that the leverage on the head portions is increased over the single pivoted constructed devices now employed, upon equal pressures being exerted on the operating handles, and that the hangers will be more easily clamped around the supportmg cable than has heretofore been possible.

It is to be understood that various sized semi-circular depressions 15 may be provided in the heads to acconnnodate supporting cables of various sizes.

Having thus described my invention what is claimed as new and is desired to be protected by Letters Patent is-- In a tool of the class described, the combination with a pair of handles formed with enlarged pivotally connected heads and adment of the T-heads is checked by the contacting of the stop shoulders on the handles, to provide an opening between the opposing faces of the T-heads through which the end of the hanger may extend.

In testimony whereof have signed my name to this speciiication in the presence of i two subscribing Witnesses.

JOHN C. KORTICK. Witnesses:

HARRY A. TOTTEN, D. B. RICHARDS.
