  • Log splitting apparatus and method of use of the same
    Patent number: 6705364
    Abstract: A method and an apparatus for splitting logs which includes a combination of an impact wrench and a conical screw-form wedge. A first step involves providing an impact wrench and a conical screw-form wedge. A second step involves coupling the conical screw-form wedge to the output coupling of the impact wrench. A third step involves placing the apex of the conical screw-form wedge against a log and activating the rotary and reciprocating movement of the impact wrench. The combined rotary and reciprocating movement of the impact wrench drives the conical screw-form wedge into the log. The described combination is a compact, portable and comparatively inexpensive log splitting apparatus.
