GRQUND-ANCHOR.

Specification of Letters Patent.

- Application filed June 2, 1910. Serial No. 564,649.

To all whom it may concern:

Be it known that I, JACOB W1Loox, a citizen of the United States, residing in Washington township, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Ground- Anchors, of which the following is a specification.

This invention relates more particularly to the sort of anchor that can be driven into the ground without preparing a hole for its passage.

The object of the invention is to provide an anchor of improved form adapted to provide a more extended surface to the earth against which it'may be pulled in propor tion to the ease with wluch it may be inserted than those heretofore proposed.

The invention is embodied in the instance of it herein shown and described, the features of novelty being pointed out by the claims appended to the description.

In the accompanying drawingFigure l is a View in elevation of thatside of the anchor containing the wire attaching lug showing also the wire and driving rod applied thereto with portions broken out; Fig. 2 is an edge view of the anchor also showing the wire and driving rod as before mentioned; Fig. 3 is an edge view of the anchor with a piece of wire attached showing the position to which the anchor is turned in the ground with reference to the wire when the latter is drawn up with suflicient force to effect the changeof position of the anchor; Fig. 4. is a view of the driving rod designed to be used in connection with the anchor.

In the views the character 5 designates the anchor or blade which is made of a thin piece of steel or other suitable metal hav- 1ng pointed or spear shaped end portions 5 and 5 of equal dimensions and like form at the ends. Thewpoint 5 is slightly curved to the side opposite that containing the wire receiving lug. The character 6' designates the said wire-receiving lug saidlug being erected on one side of the anchor body and provided with an eye 6 through which one .end of the Wire, designated 7, is passed and then twisted about itself. The eye 6 is best located directly opposite the middle of the side of the anchor and therefore at a point equidistant from the two ends of the anchor so that when the latter assumes in the ground a position at right angles to the pulled wire the resistance 'to the pull shall be approximately equal at each side.

The point 5* is the penetrating end of the anchor and the wire receiving lug is extended toward the point of said end in semicone or taper form as seen at 6 so as toprovide shoulders G and 6 at each side of the lug. The wire receiving lug is also provided with a short upward extension 6 off,- set from the face of the anchor.

8 designates the rod for driving the anchor into the ground. This rod should be sufliciently stout to withstand a hard endwise blow without flexing. The lower end of the rod is bifurcate, as seen at 8, to straddle the rod; hence as the anchor is, driven into the ground the earth is pushed aside from said tangs and does not tend to interfere with the contact of the rod with the anchor in that, operation. Indeed the lower tapered portion of the lug as shown prepares and clears a passage for the driving tool and the wire and its loop connection with the lug. The upward extension 6' holds the penetrating end portion of the anchor parallel to the driving rod.

To drive the anchor into the ground the parts are associated as seen in Figs. 1 and 2 and proper blows of a hammer or mallet applied to the upper end of the driving rod. When the anchor has been driven to a depth desired the driving rod is withdrawn and the Wire drawn upon upward thus causing the anchor to assume a position at right angles to the wire as seen in Fig. 3. In this operation the curved upper pointed end of the anchor controls the direction of movement of the anchor into the position desired and after this has been accomplished the Portions of my invention may be used without others, and variations may be resorted to within the scope of my claims.

IVhat I claim is: 1. An anchor of the kind described consisting of a blade each end of which is formed as a sin 1e spear point, each end being symmetrica in form with and of substantially the same area in plan view as that of the other, and the lower or penetrating end being substantially straight and the sisting of a blade having at one side a wire receiving lug and a tapered extension below said lug provided with laterally extending shoulders, said lug ada ted to receive a driving tool and said shou ders adapted to confront the end of said driving tool, substantially as described.

3. An anchor of the kind described consisting of a blade having at one side a wire receiving lug, a tapered extension below said lug provided with laterally extending shoulders and an upwardly extendin portion above said lug ofiset from the lade, said lu adapted to receive a bifurcate driving too straddling said lug, substantially as described.

4. An anchor of the kind described consisting of a blade having at one side a wire receivmg'lug provided with an upwardly extending portion above said lug offset from the blade, said lug adapted to receive a bifurcate drivin tool straddling sald lug between the bla e and the said ofi'set upward extension of the lug, substantially as described.
