Abstract: The present disclosure is directed towards an Improved Circular Saw Blade for simultaneous and combination cutting and chamfering a workpiece comprising a modified circular saw blade configured as a primary cutter to be mounted to one end of an arbor shaft rotatable on an axis. The modified circular saw blade comprises a plurality of substantially identical slots spaced circumferentially and extending radially inward towards the center. A modified chamfer tool is then configured as a secondary cutter to be aligned and mounted coaxially behind the primary cutter on the arbor shaft. The modified chamfer tool comprises angularly disposed peripheral chamfer blades mounted in the slots of the primary cutter so as to be displaceable transversely to the longitudinal axis of the modified circular saw blade.

Abstract: A method and apparatus for planing an article of wood. Specifically disclosed is a cutting head adapted for rotation about an axis, and at least one elongate knife including a linear cutting edge for cutting the wood. The cutting edge terminates at opposite ends of the knife in respective tips. The knife is held by the cutting head so that each tip is rotated about the axis of rotation at the same fixed radius. However, the cutting edge is misaligned by a predetermined bias angle with respect to the axis of rotation. Where a plurality of the cutting heads are stacked or ganged together, preferably, the angle of misalignment for the knives of some of the cutting heads is reversed from the angle of misalignment for the knives of others of the cutting heads.

Abstract: An apparatus having adjustable saws for wood cutting. A cutting head has at least two spaced apart disk-saws for producing respective slicing cuts in an article of wood, the saws defining respective distinct outer cutting diameters. Preferably, the disk-saws are bolted to the cutting head and spaced apart therefrom adjustable amounts by interdisposed control plates of predetermined thicknesses. Preferably, a first one of the disk-saws defines an annular ring having an inner diameter, and the outer cutting diameter for the first disk-saw is greater than the outer cutting diameter of a second one of the disk-saws. The outer cutting diameter of the second disk-saw is then less than the inner diameter of the first disk-saw, so that the second disk-saw is nested inside the first disk-saw while remaining axially displaceable therefrom.

Abstract: A stump-grinding apparatus includes a block having an inner surface and an outer surface. The inner surface is adjacent to a side -of the wheel between the center of wheel and the peripheral edge. The outer surface defines both a groove and a first aperture in the groove. A tooth is received into the groove. The tooth has a first end and a second end spaced from the first end. The second end defines a second aperture that can align with the first aperture. A fastener extends through the first and second aperture to fasten the tooth to the block.

Abstract: A wing knife holder for a chipping head includes a plinth for releasable mounting of the knife holder to the chipping head hub, a cantilevered member mounted on the plinth, the cantilevered wing inclined rearwardly and radially outwardly, from an inner end of the member support on the plinth to a cantilevered outer end of the member opposite the inner end. The leading edge of the member is forwardly swept in the direction of rotation of the chipping head from the inner end to the outer end so as to advance the outer end ahead of the inner end. A chip flow passage is formed in the plinth, radially inwardly of the leading edge between the hub and the leading edge. The chip flow passage slopes from an inner opening adjacent the peripheral edge of the hub rearwardly and radially inwardly toward the axis of rotation of the chipping head.

Abstract: An interchangeable cast metal block for mounting on a rotor shaft, the shaft having a polygonal cross-section. The block includes a substantially circular body having a central bore complementary to the polygonal cross-section of the rotor shaft such that the rotation of the shaft will turn the block. There are at least two opposed cutting blade mounting bosses for attachment of cutting blades on the external surface of the block. The mounting bosses are positioned on the block in a predetermined geometric arrangement relative to a facet of the polygonal center bore such that the block can be reversed and re-mounted on the rotor shaft to effectively double the available number of cutting blade positions. The number of available cutting blade positions is two times the number of facets on the polygonal center bore. A plurality of the blocks may be stacked on the rotor in an array to provide a plurality of cutting blade patterns along the length of the rotor shaft.

Abstract: A method and apparatus for profiling a log. In a profiler having first and second knives disposed on a rotating disc, a mounting member is adapted to mountably receive both the first and second knives so that each blade has a point on its cutting edge that is proximate a point that is on the cutting edge of the other knives. Preferably, the points are end most points and abut one another.

Abstract: The disclosure herein describes a knife holder forming part of a timber shaping and chip cutting head; the holder defines a flat shaped body bent in an open V-shape to form two integrally joined portions, one of which provides a surface for mounting upon a rotatable core and the other serves to secure the chip cutting knife. The head is formed of a plurality of adjacently disposed knife holders radially mounted on the face of said rotatable core, said face being perpendicular to the axis of rotation. The knife is removably mounted upon the knife holder in a manner that the knife can be rotated so that more than one cutting edge may be used.

The reversible disk may be removed from the generally noncircular shaft and subsequently reversed and replaced on the shaft, wherein the trailing cutting edge is transposed with the leading cutting edge.

Abstract: Shims are selectively added to, in one form of the invention, or removed from, in another form of the invention, the space between a cutter body and a circular saw blade in a cutter tool assembly for cutting a round on wood products, to compensate for the change in cutting radius that occurs when the tool is sharpened.

The holders facilitate rapid replacement of dulled or damaged cutting elements.

Abstract: Apparatus for shaping a flat surface on a workpiece includes a rotary chipper head having a plurality of radially oriented chipper knives having facing edges and chipping edges, and a circular saw blade having a diameter greater than that of the end of the chipper head closest to the workpiece. The circular saw blade is attached to the hub of the chipper head and apertures are defined in the circular saw blade to receive the ends of the knives of the chipper head, so that the chipper knives extend into the apertures in the circular saw blade. The surface formed on the workpiece is that cut by the teeth of the circular saw, and material cut from the workpiece by the saw blade is cut into chips by the chipper knives. The saw blade is thus allowed some freedom of movement relative to each chipper blade, and the facing edges of the chipper blades rotate within the kerf of the circular saw blade.

Abstract: A cone hogger unit has axially juxtaposed cutting elements resembling circular saw blades that stepwise increase in diameter from one axial end of the unit. A cutting element intermediate the axial ends of the unit is integral with a body member that has opposite axially projecting hub-like portions, each extending through cutting elements at its axial side of said one cutting element. Circumferentially spaced screws, parallel to the unit axis and at one distance therefrom, pass through the smaller diameter cutting elements and are threaded into said one cutting element. The larger diameter elements are similarly secured by other screws at a greater distance from the unit axis.
