Between these flanges a shoulprovided, which is adaptedto imbladesare opened, they assume little below ninety degrees from the shaft to allow fora-slight set in the metal under a heavy strain. The ends of the pivot 4 are ,lipset so that the blades will not become de tached:

In use the-shaft is driven into the ground by pounding with-asledge orother implemerit upon its ft into the position shown in Figsx2xand awhile itis entering. A lever 12 is then-passed throughthe opening 21 and the shaft turned two or as many times asare 1 e l 'e." 'a i i h .ear hki h i h 'sha t. s; e-M

The coneshaped point ts the shaft clears a pasageway for the supports on the blades, thus removing any obstruction, so that the blades will beprotected when entering the ground and free to open when the shaft'is turned. By distancing the hinge joints of the blades above the base of the cone there is no danger of ,earthor stones lodging on the base and preventing the blades fully extending.

While I have shown a pair of blades on the shaft, it is obvious that any number de-. sired may be used without departing from the' spirit of this invention, and I do not confine myself to the exact details of construction which have been described.

- the earth when the It is obvious that the length of the shaft can be easily modified and the form of means for twisting the shaft changed within the spirit of my invention. In one form of modification when the shaft is made extremely short the entire shaft can be embedded in the ground the vanchor being turned by a tool equivalent to the part 12 applied to the twisting means on the shaft. The claims following this specification are intended to include such modifications.

Having described my invention, what I claim as new and desire to protect by Letters Patent, is

1. A device of the class set forth, comprising a rotatable shaft, to be driven into the ground, provided with a V-shaped opening in its upper end, the apex of which is directed toward the body of the shaft, and a conical point on its lower end, the base of which is larger in diameter than the diameter of said shaft, and a screw blade provided with a double support, the arms of which are diametrically opposite each other on said shaft and above said conical point, said blade being pitched to unfold by the resistance of shaft is turned in one direction and-to rest upon said shaft when reversed, and provided with a stop shoulder for limiting its unfolding movement at less than ninety degrees from said shaft.

2. A device of the class set forth, comprising a. rotatable shaft, to be driven into the ground, provided with a V-shaped opening in its upper end, the apex of which is directed toward the body of said shaft, and a conical point on its lower end, the base of which is larger in diameter than the diameter of said shaft, and a screw blade provided with a double support, a curved cuttin edge, and a stop shoulder to limit its un olding movement.

3. A device of the class set forth, comprising a substantially round, rotatable shaft, to be inserted into the ground, provided with a V-shaped opening in its upper end, the apex of which is directed toward the body of said shaft, and a conical point on its lower end, the base of which is sli htly larger in diameter than the diameter 0 said shaft, and screw blades pivoted to, and adapted to unfold when, the shaft is turned,

each of said blades being provided with a stop which limits its unfolding movement, a cutting edge, and a double support, the arms of which are diametrically opposite each other on said shaft.

4. A rotatable shaft to be first driven into the ground and then twisted and havinga cone on its lower end, the base of said cone being larger in diameter than the diameter of said shaft, and an unfolding screw blade hinged upon said shaft and having a forward cutting edge adapted to reduce the force necessary to unfold said blade by the turnin of said shaft and a stop to limit the unfoldlng movement, said hinge attachment placed to distance said blade above and out of contact with saidbase when unfolded.

5. A rotatable shaft to be first driven into the ground and then twisted and an unfolding screw blade having a pair of flanges astraddle said shaft, and a shoulder between said flanges and a transverse pivot through said shaft and said flanges, said flanges and shaft forming a hinge jointfor said blade on said shaft and distancing said blade out of contact with the base of said cone when extended and said shoulder forming a stop for said blade against said shaft to limit the unfolding moveifibpt of said blade.

6. An earth anchor, ble shaft to be inserted vided with turning means end and a conical point on its lower end, the base of which is larger in diameter than the diameter of said shaft and a screw blade provided with a double support, the parts of which are adapted to straddle said shaft and are pivoted thereto whereby said blade is adapted to unfold when said shaft is turned in the ground, said blade having an edge becomprising -a into the ground protween said supports adapted to impinge against the side of said shaft to limit the unfolding movementof said blade.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

said pivot with upon its upper It is hereby certified that the ass'ignee in Letters Patent No. 1,04%870, grented November 19,- 1912, upon the'application of Cleude D. Enochs, of La Crosse, Wisconsin, for an improvement in Guy-Wire Anchors, was erroneously described and specified as a corporation of West Virginia. whereas said assignee shoiild have been described and siiecified as a corporation of Wisconsin; and that the said Letters Patent should be read with this correction therein thait the same may conform to the record of the casein the Patent Ofiice.
