Description:
This invention uses a slightly conical Bramah-style disk cutterhead with two different types of knives: one type, at the disk periphery undergoes a slight "dishing" motion to sever the wood fibers and roughly plane the board flat. The other type of knife, arranged radially on the cutter disk, contacts the stock only when the grain of the stock is roughly perpendicular to the movement of the knives, producing a clean finish cut. All very nice, but the owners of the Woodworth patent had already used litigation to expand the scope of their patent to include any type of cylindrical or conical cutterhead, and this patent would not have withstood a challenge. See also patent 6,185 for another unsuccessful attempt by Barnum and Wells to avoid the Woodworth cartel.
