To (bl/Z whom, it may concern.-

Be it known that we, CHARLES HANDEL and GEORGE E. NELSON, citizens of the United States, residing at Redfield, in the county of Dallas and State of Iowa, have invented a new and useful Earth-Anchor, of which the following is a specification.

Our object is, first, to save the labor and expense incident to digging holes in the ground for the purpose of fixing anchors therein to be connected with posts for supporting telephone and telegraph posts; second, to provide an anchor with self-adjusting spiral cutters that can be folded against the anchor to be therewith driven into the ground or to enter'a hole made by means of a stake or otherwise and folded outward when the anchor is rotated, as required to sink and fix the anchor in the ground by rotating the anchor; third, to provide an anchor that can be readily forced in the ground by means of a wrench, as required to securely fasten it with: out first digging a hole or filling and tamping in loose ground or concrete.

Our invention consists in the anchor hereinafter set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- Figure 1 shows the spiral cutters folded against the body portion of the anchor, as required to be forced into the ground without lifting any ground. Fig. 2 shows the adjustable spiral cutters extended as required to fasten the anchor in the ground therewith in the manner an earth-auger is sunk and fastened in the ground by rotating it. Fig. 3 is a top view of Fig. 2. Fig. 4 is a side view of the anchor that shows the end of one of the spiral Fig. 5 shows the anchor embedded in the ground and the cutters extended at right angles from the anchor, as required in'practical use for fastening the anchor in the earth.

The numeral 10 designates the body portion of the anchor, that is a straight metal bar I provided with an angular extension 12 at ltstop of smaller diameter and adapted for applying a wrench thereto. A handle 13 is fixed in the top by placing its lower end in a mold and casting the anchor 10 in the mold or in any suitable way. It is obvious the body portion of the anchor 10 may vary in size, as required for supporting posts of different size and for difli'erent purposes. The lower end of the body portion 10 terminates in a coneshaped extension 14., that is larger in diameter at its top than the body portion 10 and produces an annular shoulder adapted to be readily forced into the ground by striking on the top end of the handle'13 or by rotating it by means of a wrench applied to the angular top 12.

In an open slot in the lower end of the body 10 is a transverse open-ended slot, in which are pivoted spiral-shaped cutters-15 in such a manner that they can be turned up, as shown in Fig. 1, or extended at right angles, as shown in Figs. 2 and 3, to extend at right angles and supported upon the annular shoulder at the bottom of the slotted body portion 10.

In the practical use of our invention it may be inserted in a small hole when the cutters are in a vertical position or driven some distance into the ground by pounding on its top and then sunk deeper by applying a wrench to the angular part 12, and as it sinks deeperthe spiral cutters will be drawn downward and spread to be securely fastened in removing any ground.

To lift the anchor from the ground, it must be rotated in a reverse way, as required to fold the cutters 15 upward and against the body portion 10, so it can be pulled out by manual force or otherwise.

Having thus set forth the purpose of our invention and its construction and manner of use, its practical operation and utility will be readily understood by persons familiar with the art to which it pertains.

W hat we claim, and desire to secure by Letters Patent, is

1. In an earth-anchor, a body portion having an angular top end adapted for applying a wrench thereto, a pointed extension at its lower end, an annular shoulder at the top of said extension and an open slot extending upward from said shoulder and spiral cutters pivoted in the lower end of the slot to fold upward.

. 2. In an earth-anchor, a body portion having an angular top end adapted for applying a wrench thereto, spiral cutters pivotall y connected with the lower end of the body portion adapted to fold upward and pointed extensions below the cutters and means to limit the cutters in turning downward, for the purposes stated.

3. In an earth-anchor. a body portion havthe ground without apart, as shown in Fig. 5, as requiregh BEST AVAlLABLE COP combined to operate in the manner set forth for the purposes stated.

CHARLES HANDF-L. G. B. NELSON.-

ing an angular top end adapted for applying a wrench thereto, spiral cutters pivotally connected with the lower end of the body portion to fold upward and apointed extension below the cutters and larger in diameter at its top itnesses:
