Description:
Wilhelm & Bonner - patent attorneys

This invention relates to a wood-splitting machine, which is especially desirable for cutting blocks of wood into small pieces of the proper size to be fed to a grinding-mill for making wood pulp or other purposes. My invention has for its object to produce a simple and powerful machine whereby blocks of wood may be easily and rapidly split, and which can be operated with a comparatively small expenditure of power.

I claim as my invention—

1. The combination, with the stationary frame and the crank-shaft, of a guide or cross-head, a pitman operated by the crank-shaft and pivotally connected to the cross-head, and an ax or cutter attached to the pitman and receiving a vertical and lateral movement therefrom, substantially as set forth.

2. The combination, with the stationary frame and the crank-shaft, of a guide or cross-head, a pitman operated by the crank-shaft and pivotally connected at its lower portion to the cross-head, and an ax or cutter rigidly connected to the pitman, substantially as set forth.

3. The combination, with the stationary frame of the machine and the cross-head guided upon said frame, of a pitman pivoted at its lower portion to said cross-head and carrying a cutter, and a crank-shaft operating aid pitman and arranged out of center, whereby the cutter receives a nearly vertical movement in entering and a lateral or prying movement in finishing the cut and beginning the upstroke, substantially as set forth.
