, The present invention relatesto new and useful improvements in means for bracing upright structures, particularly fences, tele- 5 like. y 7

The invention includes a novel anchor element provided with means for retaining the,

same embedded within the earth. Theprincipal object of the invention is to provide an I 10 anchoring element for brace members which I will efficiently withstand a tremendous stress. Another object of importance is to provide a brace of this character which will not only be efficient in use, but because of its brief construction is capable of being manufactured at a very low cost.

These and other'objects of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter;

In the drawings 1.. 1 Figure 1 is a side elevation of the improved anchor element engaged by a suitable tool in the proper position. for immediate insertion within abore made in the earth. l

Figure 2 is a side elevation of the engaging end of the tool for inserting the anchoring element into the earth.

Figure 3 is aside elevation. of -a slightly modified form of the anchoring element.

Figure 4 is a top plan View of the'anchoring element shown in Figure 1.

Figure 5 is a side edge elevation of themodified form of the invention.

a Figure 6 is a sideelevation ofthe cutting end of a bore forming tool. I

Figure 7 is aside edge elevation of the bore forming tool at the lower end portion thereof the plate 8 and in opposite directions.

The plate 3 is formed with an opening 6 adjacent its edge 7 and substantially opposite the intermediate portion of one of the fins I n A guy element? is provided with'aloop 8,

graph and telephone poles, towers and the Referring'to the drawings, wherein like anchor.

.at its lower end, theuloop. being 7 disposed through the opening 6 in the manner shown. I InFigureB of the drawings, there is shown a slightly modified form of the invention, wherein the plate 3' although of polygonal shape is preferably elongated, substantially in the manner shown. The plate 3' is struck out at opposite sides of the intermediate and longitudinally extending portions 4: topro vide a pair of right angularly disposed fins 5".5, and a connector 9 connecting the in-' termediate portion 4' tothe edge portion of" the plate 3". The-plate is thus provided also with a relatively elongated fin 10, disposed in the opposite direction respective to the fins 55. I An opening 6 is formed in the edge portion of the plate 3 on the longitudinal axis of the connector 9 for receiving the loop 8' of a guy element'7.

As is shown i Figures 6 and 7, a tool is provided for forming a bore in the earth,'to receive the novel 'anchoring element. This tool comprises a shank 11 of suitable length, and an enlarged substantially circular head 12'on the lower end of the shank provided with a cutting edge 13. In Figures 1 and 2, a'tool is shown for in- I serting the anchoring element into the bore formed by the tool described above. This in- J serting'tool consists in construction of a rod 14 of sufiicient length. The rod is bifurcated at itsv lower end to provide a pair of legs 15-15, I between which the anchoring ele-' ments may be engaged prior to the forcing of f the same downwardly within the bore formed 8 in the earth.

As is shown in Fig. 1, the plate 3is inserted 7 into the ground bore in'the position whereby after the tool 14 has been removed, a pull on the strand 7 will twist the plate so that A the fins 55, are disposed at right angles to the direction of the earth bore, and by sulficiently pulling on the strand 7, the fins will bite into the earth and provide a positive It may also be desirable to first pour water intothe bore so that after the plate has been swung bya pull on the strand 7, the fins 55 I will bank against the soft earth within the bore, thus compressing the earth immediately 10b above the fins to increase the efliciency of the anchor.

Obviously, changes may be made in the specific shape, size, and materials in the manufacture of this brace Without departing from the spirit or scope of the appended claim.

Having described the invention, What is claimed as new is:

An anchor of the character described comprising a plate having an opening therein, a guy member secured to said plate, through said opening, said plate having its intermediate portion struck out to provide a pair of oppositely disposed fins spaced in such a manner as to provide a guide for a driving tool.

In testimony whereof I affix my signature.

OTTO O. HAHN.
