Description:

"This engine is designed to reduce blocks of wood to pulp for the manufacture of paper mainly, the method by which I reduce the wood to a fine granular condition consisting in the employment of two circular stones, disposed one of the other within a suitable curb, one of such stones, preferably the lower, being rotary, and the other stationary, while the resulting grinding action effects the requisite disintegration of the wood."
