PATENT oFFlcs.
WISCONSIN, ASSIGNOB TO LINE MATERIAL COH- WISCONSIN, A. GOBPORATION.OI' WISCONSIN.
CUSHION-HEAD INSULA'I'OR PIN.
Application filed November 15, 1922. Serial No. 001,067.
To all whom it may concern:
Be it known that I, WILLIAM D. KYLE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and usefullmprovements in Cushion-Head Insulator Pins, of whichthe following is a de-- scription, reference being had to the accompanying drawings, which are a part of this specification.
The invention relates to insulator pins. The object of this invention is to provide an insulator pin of simple, and economical construction 1n which a soft metal wire forms a thread to receive the insulator and acts as a cushion to prevent-cracking of the I insulator when screwing it onto the pin member or when the pin-member itself contracts and expands in service.-
The invention further-consists in the several features hereinafte'i'setiforth and more particularly defined'bycl-ai 'ms at the concluslon hereo I In the drawlngs: :Fig. 1 is an elevation view of an insulator pin embodying the invention; Fi' .2 is a vertical sectional view through the head of the pin; Fig. 3 is a top view of the pin,"and F i 4 is a detail view of a wire forming the t read.
In the 'drawin the numeral 5 designates r ha'v'n a shank portion 6 threaded atits outer. and 7, and a conical or tapered .head portion 8 provided with ank portion 6 is rovided with a bossor flange portion 10 avin a wrench-engaging'part 11. The shank be ow the portion 10 is adapted to be worked down through an opening 12in a cross-arm 13, or
metal, such .and
other suitable support, and the pin is then secured by a clamping engagement with said am y the portion 10 and a clamping nut A wire, suchas the wire 15, made of soft as lead, or the wire shown in Fig. 4, having a relatively hard metal wire 16 forming a core and a soft metal covering 17, is adapted to be wound around the,
threads 9 to sulator 18.
In each instance, and more particularly shown in Fig. 2 in connection with wire 15, the ends of the wire are anchored in the head by inserting them in transverse holes or reces'ses 19.
By the term soft metal wire as used in the claims, I mean either a wire consisting entirely of soft metal or one having a soft metal cover' What I claim as my invention is:
1. In an insulator pin, the combination, with a pin member provided with a tapered threaded head, of a soft metal wire seated in the grooves formed by said threaded head projecting therefrom to form threads for the insulator, said member having transversely extending recesses in the head receiving the ends of said wire.
:2. In an insulator pin, the combination, with a thread head, of a soft metal a'har'd metal core and mounted on said head to form threads for the insulator.
t In testimony whereof, I afiix my signauml v form'threads engaged by the inwire having WILLIAM B. KYLE.
