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 log processor and log processing method scans a log (L) at a first station (18) so that the longitudinal centerline (32) and a sawing scheme for the log can be automatically determined by a controller (4). The log is oriented at a second station (24) so that the longitudinal centerline is oriented with respect to a vertical plane passing through the feed line. The position of the log is automatically adjusted at third and fourth stations (36, 42) so that the saw blade path (56) through the log is generally parallel to the feed line as the log passes a log exit (12) and through a saw (14). The sawing scheme can include variable tapering sawing from split taper sawing to full taper sawing. Differential steering chain assemblies (37) may be used at the fourth station and may each include continuous loop, log-engaging chains (106) which engage the log above and below the log. Log chipping, profiling heads (62) may be used on either side of the feed line, such as at a fifth station.
Abstract: A method and an apparatus for splitting logs which includes a combination of an impact wrench and a conical screw-form wedge. A first step involves providing an impact wrench and a conical screw-form wedge. A second step involves coupling the conical screw-form wedge to the output coupling of the impact wrench. A third step involves placing the apex of the conical screw-form wedge against a log and activating the rotary and reciprocating movement of the impact wrench. The combined rotary and reciprocating movement of the impact wrench drives the conical screw-form wedge into the log. The described combination is a compact, portable and comparatively inexpensive log splitting apparatus.
Abstract: The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.
Abstract: A peripherally driven veneer lathe employs a knife with an improved shape which increases the deflection resistance of the cutting edge and improves its cutting ability. A cutting edge (7c) is positioned on the flank side a predetermined distance (H) away from a point (X) of intersection of an extended plane of a cutting face (7a) and that of a flank (7b) of a knife (7) toward the downstream of the rotation of a log. The cutting face immediately following the cutting edge (7c) is formed as a connecting curved surface (7d) coinciding with a concentric arc distanced from the trajectory (G) of rotation of piercing projections (4a) of a peripheral-drive member (4) with a predetermined gap (S). Preferably, the angle (&agr;) formed by a line (D) tangent to the connecting curved surface (7d) at the cutting edge and the flank (7b) is roughly equal to the sharpness angle (&bgr;: 18° to 25°) of the conventional knife.

Abstract: A mobile silvicultural apparatus for use in a land of trees comprising mature trees and immature trees. The apparatus includes a steerable wheeled support frame, an articulated boom, a motor system, and a control system. The steerable wheeled support frame has a horizontally extending ground-clearing section, and first and second opposite vertical side sections. The ground-clearing and side sections define a tunnel-shaped passage through which the immature trees are allowed to pass as the support frame travels thereover. The articulated boom is mounted to the support frame for selectively manipulating the mature trees. The motor system is used for imparting motion to the support frame and the control system is used for controlling the steerable support frame, the motor system, and the articulated boom.
Abstract: An apparatus includes a structure supporting a circular blade, a carriage on the structure for linear movement relative to the blade, and a lathe mounted on the carriage, the lathe rotatably supporting a workpiece in proximity to the blade. In one aspect, the support structure is pivotally connected to the carriage to allow pivoting of the lathe between an orientation for engagement of the workpiece with the blade and an orientation in which the workpiece is supported remote from the blade to facilitate operations on the workpiece with a tool implement other than the blade. In another aspect, the support plate is moveable with respect to the carriage in a direction orthogonal to a line parallel with the direction of allowed movement of the carriage relative to the frame, and a pattern plate is mounted to the support plate to control workpiece depth of cut.
Abstract: A log catcher for catching and holding logs which fall from a log splitter which is supported upon an I-beam. The log catcher comprises five parallel cylindrical rods each having two ends, a horizontal first cross-beam attached to the rods at one end, and a horizontal second cross-beam attached to the rods at the other end. The log catcher further comprises an angular cross-beam having evenly spaced holes through which the rods extend at a point which is substantially closer to the second cross-beam than to the first cross-beam. All five rods are evenly spaced throughout. Each rod has a right angle bend, thereby forming a curved portion, wherein the falling logs may be effectively contained. In use, the log catcher is positioned below the I-beam, and the second cross-beam and the angular cross-beam effectively bracket the lower surface of the I-beam, thereby imparting additional stability to the log catcher.
Abstract: This invention relates to a two-piece grommet adapted for holding a cable in an aperture, such as in a desk or work surface so as to absorb any strain imposed on the cable and to provide an attractive covering for the hole drilled to pass the cable. The grommet consists of two portions. The first portion comprises a cylindrical sleeve having a circular lip. The second portion comprises a cap having an extended flange and adapted to frictionally fit into the cylindrical sleeve and against the lip. The cap has an aperture cut into it through which the cable passes. A pivotal tab is connected under the cap to close the aperture when no cable passes therethrough.

Abstract: The two boom members and hydraulic cylinders of a knuckle boom tree harvesting machine are so arranged and proportioned that with a single control movement during reaching and retracting actions the working tool head is made to travel in an approximately horizontal path. The cylinders and control valve are so connected that during horizontal reaching action load-supporting pressurized oil from a collapsing cylinder is not required to be dumped to the reservoir in the conventional heat generating manner, but is rather shunted directly to an extending cylinder where it continues to do useful load support work. Energy waste to hydraulic oil heat and fuel consumption is significantly reduced. Although these advances have been particularly developed for disc saw felling and stroke delimbing of trees they can also be applied to other knuckle boom applications where horizontal reaching is a major function.
