ABSTRACT:
An adjustable log-splitting apparatus of the type wherein a wedge-shaped cutter is slidably received on a vertical column for splitting logs placed therebeneath includes the improvement of a base platform having a top plate member and a supporting frame member wherein the top plate member is able to be raised by a foot treadle and once raised, is able to be manually rotated about a central pivot axis relative to the supporting frame member. Pivotal movement of the top plane member relative to the supporting frame member is achieved by means of a cylindrical post which is both slidably and pivotally received within a closely sized aperture. In a static condition, the top plate member rests on the outer periphery edge of the supporting frame member. However, when the foot treadle is depressed, four rollers are pivoted into a raised orientation thereby drawing these rollers into direct contact with the underside of the top plate member and actually raising the top plate member up off of the supporting frame member. The action which brings these rollers into contact with the underside of the top plate member also orients the axis of rotation of these rollers into the same horizontal plane and each axis line intersects the axis of rotation of the top plate member relative to the supporting frame member.
