Description: |
| Parker, Prochnow & Farmer - patent attorneys"This invention relates to improvements in machines for grinding wood to produce pulp, and more particularly to grinders of the type shown in my Patent No. 2,282,887 of May 12, 1942, in which wood is fed to the grindstone by means of a feed ring arranged eccentrically about the grindstone. In machines of this type, the feed ring is of considerably larger diameter than the grindstone, thus forming a converging space in which the logs are pressed against the grindstone by the feed ring. At the end of this space, the grindstone and feed ring are spaced apart by a slight gap and the parts of the logs adjacent to the inner surface of the feed ring, consequently, pass through this gap without being ground. One of the objects of this invention is to provide means of improved construction for disposing of the shims or remnants of wood or logs after they have passed through the space between the feed ring and the grindstone. Another object is to provide a grinding machine of this kind with means of improved construction for conveying the shims or thin remnants of wood, after they have passed the grindstone away from the discharge side of the grindstone. Another object of this invention is to provide a shim conveyor which automatically carries the shims from the discharge side of the grindstone to the feed side thereof for grinding..." |
