Patent number: 5329978Abstract: The invention provides an improved planar which effectively prevents undesirable torn grain. The planer of the invention includes at least one planer knife or blade and at least one pressing member, both attached to and supported on a cutterhead. The pressing member includes a head element which is located to have a predetermined angle with respect to the blade and is resiliently movable in a predetermined direction to press an edge of the head element against a certain position of a wood surface immediately before a cutting edge of the blade moving in a fixed direction for cutting or against a boundary between the wood surface and a chip being currently cut from the wood surface. The direct pressing of the pressing member against the wood surface prevents rise of wood fibers and thereby effectively reduces or eliminates undesirable torn or chipped grain.Type: GrantFiled: April 23, 1993Date of Patent: July 19, 1994Assignee: Meinan Machinery Works, Inc.Inventor: Katsuji Hasegawa

Patent number: 4749014Abstract: A cutterhead for a power planer has an elongated core with threaded holes for releasably mounting a pressure plate with a cutting blade being clamped between the pressure plate and the core. The core has a support surface contacted by the cover portion, a contact surface contacted by the pressure plate, and a transition surface therebetween. The support surface is inclined to the contact surface at a angle of more than 180 degrees and less than 270 degrees. This arrangement helps compensate for tolerances associated with the securing screws, and reduces any tendency for imbalance in the cutterhead when rotating. A pair of cover portions may support opposite sides of the cutting blade adjacent its cutting edge. The cutting blade may be a profile blade.Type: GrantFiled: June 15, 1987Date of Patent: June 7, 1988Assignee: Black & Decker Inc.Inventor: Gerald Schlund

Patent number: 4347882Abstract: The invention is directed to a rotary cutterhead for a portable power planer tool, as well as a method of making the cutterhead. The cutterhead includes an elongated core and a pressure plate mounted on the core and which cooperates therewith to define a slot-like opening for receiving a cutting blade and locating the cutting edge thereof relative to the cutting circle of the cutterhead. The pressure plate is positioned and fixed in a permanent location relative to the core so that the cutting edge of any standard cutting blade of predetermined dimensions will extend from the opening beyond the cutting circle of the cutterhead a preferred optimum distance for performing a planing operation. The cutterhead includes a cover portion having a clamping edge which biases the pressure plate toward the core when the cover portion is tightened so that the two cooperate to clampingly retain the cutting blade within the opening.Type: GrantFiled: October 7, 1980Date of Patent: September 7, 1982Assignee: Black & Decker Inc.Inventor: Rainer Bachmann
