Abstract
Abstract An anchor drive coupler for use in interconnecting an earth anchor with the drive mechanism used for embedding the anchor deeply into the ground, the coupler includes a sleeve, having upper and lower closure plates rigidly secured therewith, and an adapter connects with the upper plate for securement of the coupler with the drive mechanism, while the upper portion of the earth anchor is pinned to the said sleeve or a lower adapter secured therewith, for furnishing interconnection between the drive mechanism and the earth anchor so that driving torque will be transmitted for effecting a deep penetration of the anchor into the ground during its installation.
