ABSTRACT:
Apparatus for splitting logs including a base, a platform for supporting on end a log to be split, and a post mounted on the base. An axe head with a downwardly directed cutting edge is slideably received on the post which, in turn, is provided with a plurality of recesses facing in the direction of the cutting edge. A link extends between a handle and the axe head and is pivotally connected at its ends to the handle and the axe head. A fulcrum pin at one end of the handle is receivable in one of the recesses when the cutting edge is rested upon an upper end of the log. When a transverse force is applied to the end of the handle distant from the fulcrum pin, the handle is caused to rotate about the fulcrum pin from a raised position toward a lowered position forcing the cutting edge to enter the upper end of the log. With continued rotation of the handle, the cutting edge advances into the log toward its lower end at an ever faster rate, but with ever decreasing force. The location of the fulcrum pin can be readily changed to obtain greater speed or force of the cutting edge through the log. The handle and the axe head may be maintained in a rest position adjacent to the operating position in preparation for placement of another log into position to be split, and a second handle may be provided for an even greater mechanical advantage.
