FRED M. LOCKE, OF VICTOR, NEW YORK.

lNSULATOR-PIN.

SPECIFICATION forming part of Letters Patent No. 701,063, dated May 27, 1902.

Application filed November 15, 1901. fierial No. 82,408. (No model.)

To all whom it may concern:

Be it known that I, FRED M. LOCKE, of Victor, in the county of Ontario, in the State of New York, have invented new and useful Improvements in Insulator-Pins, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in insulator-pins, having more particular reference to the thimble and means for holding the same upon the bolt or support which is secured to the cross-arm.

My object is to produce a pin having a detachable thimble in which the bolt or support may be easily andreadily inserted and when the thimble is so mounted it will be held against vertical displacement and rotary movement, and to that end my invention consists in the several new and novel features of construction and operation which are hereinafter described, and specifically set forth in the claims hereunto annexed. It is constructed as follows, reference being bad to the accompanying drawing, in which I show a pin or support suitably mounted upon a crossarm and provided with a thimble in section mounted upon the upper end thereof.

a is a pin, which is secured to the crossarm I), the pin a being of any form shown, but preferably the upper end 0 gradually increases in size as it approaches the cross-arm b, as shown at 0, so as to afford lateral support for the top of the pin. The upper end of the pin is provided with downwardly-extending barbs d, and e is a thimble having a recess 6', by which it is mounted onto the upper end of the pin d. The thimble e is preferably of wood, so that the barbs d will embed themselves into the inner recess of the thimble and prevent its being withdrawn, at the same time preventing rotation. The thimble is also provided with threads f or other means by which the insulator may be secured thereon.

I do notlimit myself to the form of the upper end of the pin, as it will be evident that it may be made either circular or angular, and when made angular it will prevent the rotation of the thimble thereon of itself irrespective of the barbs.

The recess 6 is made of a size just large enough to allow the thimble to be forced down over the pin, so that when once it is thus forced down it will be impossible to with draw the Thimble.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. An insulator-pin comprising a metallic support having its upper end provided with barbs and an insulatingthimble mounted thereon.

2. Apin comprisinga metallic supporthaving its central portion enlarged for the purpose of giving lateral support to the pin and having its upper end provided with barbs and an insulating-thimble mounted thereon.

3. An insulator-pin comprising a metallic support having its upper end constructed so as to prevent the rotation of the thimble thereon, said end being provided with barbs and an insulating-thimble mounted on said support.

In witness whereof I have hereunto set my hand this 12th day of November, 1901.

FRED M. LOOKE.
