ABSTRACT:
A log splitter comprising: a base; a lever having one end portion hingably attached to the base; a wedge slidably attached to a hinged end portion of the lever, to slidably reciprocate along the lever when the lever is swung; a log support for a cut log; and, an upper end log restraint slidably positioned on the lever, said log restraint having a pawl, and the lever having teeth therealong, so that the log restraint can only slide towards the cut log. When the lever is swung down the wedge is forced into the cut log, and when the lever is lifted the wedge is slidably pulled back along the lever thereby pulling the now partially split log so that the upper end log restraint freely slides along the lever. When the lever is again pushed downwardly the cycle is repeated. The lever may be pushed with a foot pedal.
