Abstract
Various sheet-like materials require fastening to the ground. Included in such materials is a blanket comprised of netting and excelsior. A device for driving U-shaped anchors downwardly so as to secure the blanket to the ground at selected locations comprises a shoe having a sole plate that is adapted to engage the netting or other upper surface of whatever sheet-like material is to be anchored. The sole plate has a transverse slot through which a plunger is moved downwardly when a U-shaped anchor has been advanced into alignment beneath the plunger. The plunger is carried at the lower end of a reciprocable piston rod which has a piston at its upper end. By means of a foot-operable valve, compressed air is introduced into the upper end of the cylinder, thereby forcing the piston, the piston rod and the plunger downwardly so as to force an anchor into the ground. The downward movement of the plunger is limited by means of a stop that is struck by a collar attached to the lower end of the piston rod. The device is portable and can be readily transported from site to site in the anchoring of sheet-like material which can include sod and various flexible plastic sheets.
