Abstract: A chipper machine for simultaneously preparing a flat surface on a workpiece and comminuting material removed from the workpiece to produce the flat surface, in which several individually removable chipper knives are mounted on a hub mounted detachably on a rotatable arbor. A workpiece-supporting anvil includes a drop front section to permit removal of the chipper head from the arbor. The hub and arbor are steeply tapered to allow the chipper head to be easily removable from the arbor, and the chipper machine is provided with sharpened chipper knives by replacement of the entire chipper head. The several chipper knives are removed, sharpened, replaced, adjusted and again ground to cut uniformly with the chipper head removed from the chipper machine.

Abstract: A wood chipper embodying a pair of adjacent discs mounted in face-to-fact relation on a drive shaft for rotation therewith. The discs are secured to each other and have angularly spaced aligned passageways therethrough. A recess is provided in one disc at the trailing side of each angularly spaced passageway, as viewed in the direction of rotation. A knife holder mounted within each recess carries a knife which is retained by a knife clamp. Interlocking means between the clamp and the knife holder limits relative movement therebetween both axially and radially to maintain accurate location of the knives. The end of the knife holder removed from the aligned passageways is spaced from its disc to define a cavity which receives babbit. Also, the edge of the knife opposite its cutting edge is spaced from the knife holder and may have slots which extend at an angle relative to the cutting edge to define cavities which receive babbit. The inner surface of the knife clamp flares outwardly at an angle away from the cutting edge of the knife to press the clamp against the knife near the cutting edge thereof.

Abstract: A comminuter for metal turnings and the like has a rotor rotatable on a support about a fixed axis and carrying at least one outer rotor element and at least one inner rotor element which define a cylindrical orbit on rotation of the rotor. A housing surrounds this rotor and is formed by a U-shaped upwardly open portion of non-tapering cross-sectional shape and a flat cover part engageable over the open upper side and openable in order to clear a jam in the machine. Stator elements carried on this housing are spaced slightly from the rotor element so that as the rotor turns turnings and the like fed to the machine will be comminuted and passed from an inlet to an outlet end.

Abstract: An arrangement for adjusting the compressive force of drive rolls used for advancing a tree along a feed line for lopping. Drive rolls are arranged on opposite sides of the tree trunk and driven by hydraulic motors. Each drive wheel is pivotably mounted on its own arm and a cylinder-piston is connected between the arms and is used to adjust the distance between the drive rolls and to produce a compression force between them. A hydraulic circuit is provided which includes a drive motor, a pressure reducing valve and the cylinder-piston. The tank connection of the control pressure of the pressure-reduction valve is connected to the working pressure of the hydraulic motor so that when the rolls require a low rotating force the compression pressure created by the cylinder-piston is low and when the rolls require a high rotating force the working pressure required by the hydraulic motor increases and this working pressure increases the compression forces exerted by the cylinder-piston.

Abstract: A cutter shaft for a wood machining apparatus is provided with at least one pocket in which a cutting knife is arranged between a pressure plate and a wear part with the cutting edge of the knife projecting beyond the peripheral surface of the shaft. A wedge located in a cutout of the shaft, intersecting the pocket, is guided in the cutout movable substantially in radial direction of the shaft and engaging with a wedge face, inclined at a predetermined angle with respect to the radial direction, a corresponding face of the pressure plate to press the latter against one side face of the knife and therewith the other side face against said wear part. The aforementioned angle between the two engaging faces is outside the self-locking range and at least 35.degree. and preferably about 42.degree.. The wedge is biased by a spring in radial outward direction and, during rotation of the shaft, also by centrifugal force.
