ABSTRACT:
Apparatus for splitting logs adapted for use with a power head of a chain saw comprising a screw jack mounted for rotation on the interior of a support channel, the input end of the screw jack being connected through a plurality of reduction gears to a drive sprocket. The screw jack itself is in turn threadably engaged to a travelling axe head conformed for sliding translation within the support channel. A part of the axe head is shaped as a wedge projecting beyond the confines of the channel to advance therealong towards a V-shaped stop bracket. An eliptical cam is mounted for rotation in the thick end of the wedge to be articulated from its narrow alignment to a broad alignment by an articulating lever disposed to advance against one of the legs of the V-shaped stop bracket. As the eliptical cam is thus rotated, expanding the lateral dimension of the axe, separation of the split is achieved.
