GROUND-WIRE FASTENER.

Specification of Letters Patent.

Patented aug.y 22, i911.

Application led March `15, 1911. Serial No. 614,724.

To all whom it may concern:

Be it known that I, MILTON H. LAWRENCE,

' citizen of the United States, residing at Larned, in the county of Pawnee and State of Kansas, have invented certain new and useful-Improvements in Ground-Wire Fasteners, of which the following is a specific-ation.

This invention comprehends certain new and useful improvements in electrical conductors, and the invention has for its primary object a simple, durable and efficient construction of ground line conductor or fastener, which is composed of few parts that may be easily manufactured and assembled and which is so arranged that the wire to be grounded may be easily secured thereto or detached therefrom whenever delsired, the device being easily operated to placethe ground wire under thed'esired tension and to securely hold the same without l the use of soldering. And the invention also has for its object a simple device of this character which may be used again and again, the parts being so arranged that the Wire may be easily released whenever required.

` lVi h these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a sectional side elevation of my improved ground wire fastener; and, Fig. 2 is a detail perspective view of the thimble of the device. y

Corresponding and like parts are referred to in the following description and indi-V cated in all the views of the drawings by the samfe reference characters.

My improved ground rod or ground wire fastener, comprises a post or standard l intended to be driven into the ground, said post being formed near one end with a tapered portion 2, the larger end of which is disposed outermost in preferably slightly spaced relation to a rounded head 3 which is formed on one end of the rod or post and which is preferably of a diameter, to extend beyond, the margin of the outer or upper end of the tapered portion 2.

4 designates a tapered thimble which is designed to slide freely on the rod l and which is adapt-ed to be slipped upon the tapered portion 2 of the rod so as to securely hold the wire. Either the tapered portion 2 or the interior Wall of the thimble 4 may be formed with a longitudinally extending groove, the thimble being provided with the groove in the present instance, as indicated at 5. 1

From the foregoing description in connection with the accompanymg drawing, the operation of my ground wire fastener wl be apparent. When the device is to be used, the wire to be grounded is passed through the groove 5 between the rod and the thimble, and the lower end of the wire is bent up, as clearly illustrated in the drawing. rlhe rod is then driven into the ground until the wire is at the proper tension, thereby making a tight joint without the use of solder, it being, of course, understood thatthe thimble t is slipped upon the tapered portion 2 of the rod. When the parts are in operative position, the end of the wire will not only be held by having its end turned up around the lower edge of the thimble 4 and securely wedged in between the thimble and the tapered portion 2 of the rod, but the wire will be further maintained under proper tension, owing to the fact that above the thimble 4 the wire will be given an outward bend around the head 3, as clearly illustrated in the drawing.

,In order to prevent the thimble 4- from slipping entirely off the rod, :and.z'-'thereby precluding the possibility of the thimble being lost, the rod is provided with'a transversely extending pin 6, which projects therefrom as shown, so as to limit the movement of the thimble in one direction.

v Having thus described the invention, what is claimed as new is:

l. A ground wire fastener, comprising a rod provided near one end with a tapered portion tapering toward the driving end of the rod, and a rounded head in spaced relation to said tapered portion, and of a diameter greater than said larger end and a thimble mounted to slide on the rod and adapted to be wedged upon the tapered portion thereof.

2. A ground wire fastener, comprising a rod, and means movable upon the rod for clamping a wire to the rod, the rod being formed contiguous to said means with means for forming a crimp in the wire independent of the clamping means, whereby the wire will not only be clamped to the rod, but will be crimped or kinked in close proximity to its clamped portion.

3. A ground Wire fastener, comprising a rod formed near one end with a tapered .portion and at such end with a head spaced from the larger end of the tapered portion and of a diameter greater than such end, a tapered thimble adapted to slide on the rod and to Wedge upon the tapered portion thereof, the thimble being formed in its interior wall with a longitudinal groove extending therethrough, and means on the rod to limit the movement of the thimble away from the tapered portion of the rod.

In testimony whereof, I ailix my signature in presence of two Witnesses.
