Abstract
An expanding earth anchor assembly is disclosed for attaching cable means or the like conveniently employed in supporting utility, communication, or other above ground structures. Jaws attached to an anchor rod are expandable outwardly by rotation of the rod from above the surface of the ground when the jaws are inserted to a proper depth and at an appropriate angle in the soil. An important aspect of the invention resides in protection of the anchor rod assembly located below ground level, inasmuch as anchor rods buried in the ground are ordinarily subject to an accelerated rate of electrolytic corrosion, which is avoided through practice of the invention.
