Patent number: 6330895Abstract: A log flaking and loading method and apparatus. First and second pairs of cutting heads have cutting heads spaced apart to receive a log passed therebetween and thereby to cut two substantially parallel sides. The log is first cut by the first pair of cutting heads, rotated about its elongate axis, and cut by the second pair of cutting heads to produce a four-sided cant. The logs are preferably stored ahead of the first pair of cutting heads in corresponding carriers, which are preferably held in a magazine for dispensing the loaded carriers.Type: GrantFiled: May 18, 2000Date of Patent: December 18, 2001Assignee: Key Knife, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly, Bradley R. Stager

Patent number: 5333659Abstract: A chipping cutter head including a double-edged knife and support structure mounting the knife in a pocket provided at the periphery of a cutter head body. The support structure includes a block member fastened by screws to the floor of the pocket. Adjustment structure is provided for adjusting the position of the block member, with this being effective to shift the position of the cutting edge of a knife supported on the block member. A replaceable insert member with a wear surface is positioned by a pin on the block member, and this insert member supports the knife and the knife is locked from shifting axially on the insert member.Type: GrantFiled: July 21, 1993Date of Patent: August 2, 1994Assignee: Key Knife, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly

Patent number: 5271442Abstract: A log slabbing chipper with multiple knife structures distributed about the periphery of a power-driven rotor head. Each knife structure includes a holder, and a pair of knife mounting assemblies secured to the holder. Each knife mounting assembly mounts a double-edged replaceable knife.Type: GrantFiled: February 19, 1993Date of Patent: December 21, 1993Assignee: Commercial Knife, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly

Patent number: 5209278Abstract: A drum chipper having a rotatable, power-driven drum supporting a knife. With rotation of the drum, a cutting edge in the knife is moved past a cutter bar. A knife mounting keyed to the knife is adjustably positioned along a path in the drum to position the knife. The knife is a double-edged knife, with one edge replacing the other with dulling of the latter edge.Type: GrantFiled: February 27, 1992Date of Patent: May 11, 1993Assignee: Commerical Knife,Inc.Inventors: Charles T.

Patent number: 5146963Abstract: A chipping cutter head having multiple spindle segments disposed side-by-side and forming a body in the cutter head. Circumferentially distributed pockets in each spindle segment have knife holders detachably mounted therein and held in place by clamps. Double-edged knife elements, that are replaceable, are detachably clamped in position on each knife holder.Type: GrantFiled: November 4, 1991Date of Patent: September 15, 1992Assignee: Commercial Knife, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly

Patent number: 4850408Abstract: Chipper apparatus including a rotating disc with one or more knives mounted on the disc operable to produce wood chips under the cutting action of the knives. Each knife comprises an elongate knife body bounded by opposed cutting edges. The knife includes a back side formed back knife surfaces extending inwardly on the knife from its cutting edges and the back knife surfaces meeting with a bearing surface. The front side of the knife includes front knife surfaces extending inwardly on the knife from its cutting edges joining with an elongated key-receiving channel indented inwardly into the knife body. A knife is mounted on a rotatable chipper disc through a clamp member which bears against the bearing surface of a knife and a counter-knife which supports the front side of the knife and which includes an elongate key portion fitting within the key-receiving channel of the knife.Type: GrantFiled: June 24, 1988Date of Patent: July 25, 1989Assignee: Commercial Knife, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly

Patent number: 4669516Abstract: A chipper knife includes a pair of elongate blade portions integrally joined at a midplane which longitudinally bisects the blade. The blade portions are symmetrical and have inner and outer surfaces. The outer surface intersects the midplane at an acute angle and the inner surface intersects the midplane at a lesser acute angle. The inner and outer surfaces therefore diverge from each other as they extend outward from the midplane. The outer surface of each blade portion terminates in a cutting edge. A mounting for the knife is carried on a chipper disc and includes a base for supporting the inner surfaces of the blade portion with a cutting edge thereof disposed outwardly from the disc surface and a hold down plate engaging an outer surface of the blade to secure the knife to the mounting.Type: GrantFiled: November 18, 1985Date of Patent: June 2, 1987Assignee: Duratech, Inc.Inventors: Charles T. Carpenter, Robert M. Bayly
