-June 15, 1937. B BRADFORD l 2,084,239

S-TAKE Filed April 3, 1936 ATTORNEYS,

Patented June 15, 1937 STAKE 'Bennie H. Bradford, Qxford, N. C. Appuationapnl 3, 193s, serial No. '12,604 rolaim. (C l. iss- 30) 'I'he invention relates to a ground anchoring` device and more especially to stakes.

'I'he primary object of the invention is the pro;

vision of a stake of this character, wherein the ground engaging end portion thereof is formed with a spiral and between the convolutions of such spiral the said end portion is composed of a pluralityof conical formations, the upper end of each of such formations being greater in diameter than the lower end of the next higher formation while the spiral thread is provided at opposite sides with wings, these being sharp' or narrow at their lower edges and graduallyA increase in thickness in the direction of their upper edges and the upper edges of which arenarrower than the spiral thread so that a'rm and positive anchorage can be had in the ground for supports such as posts,

eyes for tie wires, cables or the like and fixation.

of the stake is assured with dispatch and ease as well as being readily removable when the occasion requires.'

Another object of the invention is the provision of a stake of this character, wherein the construction thereof is novel in form and will assure 25 secure and rm xation in a foundation, such stake being readily anchored and removed at will! A further object of the invention is the Vprovision of a stake of this character, which is of the winged auger type and is simple in construction, 3 thoroughly reliable and effective in its operation, strong, durable, and inexpensive'to manufacture and install. v

With these and other objects in view, the invention consists in the features of construction,

as combination and arrangement of parts as will be 'hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention andpointed out in the claim hereunto appended.

IIn the accompanying drawing: Figure 1 is a side elevation of a stake constructedin accordance with the invention. Figure 2 is a vertical sectional view thereof. Figure 3 is a horizontal sectional view through thestake.v .Figurefi is a fragmentary side elevation of a slight modication.

Figure 5 is a fragmentary side, elevation of a 50 further 'modication .f

-Figure 6 is a fragmentary vertical sectional view through a foundation showing a further modied form of stake anchored therein.

Figure 7 is a view similar to Figure 6 showing 55 a still further modication.

`Similar Areference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, particularlyv Figures 1 and 2, the stake comprises a body A which has formed exteriorly thereon a spiral 'l thread I0 while the portions of thesaid body A between the thread are of conical formation as at H, the upper end of each of such formations being greater in diameter than the lower end of the next higher formation.

'I'he spiral thread is provided at opposite sides of the body A withwvings I2 which have sharpv or narrow lower edges I3 and gradually increase in thickness in the direction of the upper edges Il and each upper edge of which is narrower than the spiral thread I0. The formations with the threads I0 about the body A eiect a tapered characteristic to the said body witha pointed tip l5 at one end while at the other end is a cup shaped head I6 for the socketing therein of a post or other support which is riveted or otherwise secured in place, the holes I1 being provided for this purpose.

In Figure 4 of the drawing there ls shown a slight modication wherein the head I8 con- -stitutes an eye land linked with this eye I8 is a turning key I9 which enables the screwing of the stake into a foundation and also such key may be utilized as a terminal fastener for a tie brace or other wire or cable.

Inv Figure 5 of the drawing there is shown another modification of the invention wherein a post or other support 24. The stake is anchored in the ground or foundation through the instrumentalityv of Aa cement easement 25 which is `poured into a bore or opening as created by the stake in the anchoring thereof.

In Figure 7 of the drawingthere is shown a still further modication wherein the stake is in the form of a wire fence post 26.

From the foregoing it should be seen that the spiral thread onthe stake will permit the screw'- ing thereof into a foundation or ground and a firm and secure anchorage will be had while such stake can be readily removed from the foundation or ground as the occasion may require. i

What is claimed is:

A stake ofthe kind described, comprising a body of rounded formation and tapering in one direction, a spiral thread exteriorly of said body, invertedlconical formations between the spirals of said thread, the upper end of each of such `formations being greater in diameter than the lower end, the thread following and being located at the greater diameters of said formations, a

10 pointed tip formed at the smaller end of said body and extended beyond the terminal of che thread next to said tip and a. short spiral built on and protruding from the thread at a point close to the tip to provide a wing gradually thickened from the lowermost point to the highest point thereof, and a beveled sharp edge provided at the lowermost end of said wing, the wing being extremities of the same.
