Abstract: A chipper for cutting uniform chips from a log having a rotating disc containing a plurality of radially disposed cutting stations, each having a knife assembly positioned adjacent a chip slot. Each knife assembly has an elongated cassette having a knife receiving recess formed in the top front surface thereof. A reversible knife is located in the recess by means of a key and is held in place by a retaining bar so that one cutting edge of the knife is accurately positioned at the entrance to the chip slot. Reversing the knife in the cassette after the first edge becomes dulled similarly positions the second cutting edge. Preferably, a plurality of knives are mounted end to end in the cassette.

Abstract: A chipper for cutting uniform chips from a log has a sliver ring mounted on the rotary disc radially outside the cutting blade assemblies, and also has cooperating arcuate wrapper member and special sliver bedknife mounted on the front plate of the chipper housing. The wrapper member is concentric with the sliver ring and extends circumferentially around it for a distance, and also extends axially towards the disc and beyond the proximal face of the sliver ring to define a radial gap between the ring and the wrapper. The sliver bedknife extends across the face of the disc from one end of the arcuate wrapper. The sliver bedknife, the wrapper, and the sliver ring cooperate with one another to limit progression of slivers that are formed from wooden logs at the position of the stationary bedknife.

Abstract: A disk chipper includes a bedknife, the bedknife having opposing first and second surfaces, and a chipper frame, the chipper frame having an opening for receiving the bedknife, the opening being defined by opposing first and second surfaces for facing the first and second surfaces of the bedknife, respectively. The disk chipper further includes a wedge, the wedge being movable in a first direction between the second surface of the bedknife and the second surface of the chipper frame to move the first surface of the bedknife in a second direction substantially perpendicular to the first direction toward the first surface of the chipper frame. A method for fastening a bedknife to a disk chipper is also disclosed.

Abstract: A chipper employs a rotary cutting disk with a plurality of radial knife assemblies. Each knife assembly has a reversible blade of generally trapezoidal cross section. The assembly has a knife holder and a knife clamp that sandwich the blade between them. An elongated load bar is seated in a recess in the clamp and supports a sloping surface at a concealed edge of the blade.

Abstract: A knife holder for a rotary type wood chipper is in the form of a segment occupying a segmental portion of the proximal side of the cutting disk and extending to a chip slot of an adjacent knife from its associated knife assembly. The knife holder has a hardened helicoid proximal wear surface that faces the logs that are fed into the chipper. Each knife holder is formed of a base plate which removably mounts onto the disk and a wear plate that is replaceably attached onto the proximal side of the base plate. The wear plate is mechanically attached to the base plate by set screws and is also attached by a weld that runs along a peripheral chamfer. When the hardfacing surface on the wear plate becomes eroded, the wear plate can be removed and replaced.
