ABSTRACT:
A ground or earth anchor adapted to be driven lengthwise into the ground or placed lengthwise in a pre-dug hole in the ground and then is tilted or rotated into transverse or horizontal anchoring position by tension on a cable, rope, guy wire, rod or the like attached to the anchor. The anchor has an elongated rigid T-shaped body providing a web and two lateral flanges with a pointed leading end and down-turned sloping fins at the rear ends of the flanges causing the rear portion of the body to bite into the ground and tilt as the body is retracted. The outer or top edge of the web portion is provided with a hole to receive the cable or the like and this hole is positioned back of the longitudinal midpoint of the body so that the major area portions of the web and flanges will be ahead of the hole on the pointed end section of the body. The body is inserted lengthwise with its pointed end downwardly in the ground and has a length substantially greater than the diameter of a pre-dug hole receiving the body so that when tension is applied to the cable attached to the body, the sloping fins on the rear end will tilt or rotate the body into substantially horizontal position, while the pointed end of the body burrows or ploughs into the ground. The anchor is especially useful to secure guy wires and rods.
