Abstract: The invention is a waste processor which incorporates the advantages of the chipper knife holder 100, swing hammers 50 and hog 120. A swing hammer 54 is used, providing for the use of all the kinetic energy stored in the swing hammers 54 together with good material contact. The swing hammer 54 profile is designed to spread the impact force over a large area, thus increasing the life of the swing hammer 54. If necessary, the swing hammers 50 can be locked to the rotating disc assembly 18, preventing their contacting any material. Hog hammers 120 are placed immediately behind the swing hammers 50. The position of the hog hammers 120 is such that they provide room for the swing hammers 50 to recoil, but are close enough to impact the material in approximately the same place as the swing hammers 50. The hog hammers 120 use the much larger amount of kinetic energy that is stored in the rotating disc assembly 18.

Abstract: The invention is a tool support for a waste processor comprising a plurality of rotating discs on which can be mounted a combination of chipper knives, swing hammers, and hog hammers. The tool support has an incline surface on which the chipper knives and hog hammers are removably mounted in a position so that a portion of the chipper knives and the hog hammers extend beyond the periphery of the discs. During rotation of the discs, if the chipper knives or hog hammers encounter an object that cannot be chipped or broken, the chipper knife and hog hammer, respectively, are forced down the mounting surface of the tool holder to a position below the periphery of the discs so that the chipper knives and hog hammers are protected from further damage by the circumference of the disc.

Abstract: The specification describes a stump chipping disintegrator wherein stumps are received in a trough having a rotatable chipping disc at one end and a powered ram plate at the other, the ram plate having diagonally extending penetrators. A stump stabilizer anvil adjacent the disc projects radially inwardly of the trough. The disc has steel, wood slicing blades at the radially inner portion thereof, mounted at a small acute angle to the face of the disc toward the direction of rotation, and carbide chopping blades at the radially outer portion thereof, mounted at a large acute angle to the face of the disc toward the direction of rotation. At least the carbide blades are mounted in special holders removable from the disc. The carbide blades have backup wedge elements that extend substantially the width of the blade at its outer end and extend substantilly to the radial outer edge of the blade.

Abstract: A whole tree feeding and chipping assembly for longitudinally feeding whole trees with attached limbs and branches to a chipper wherein the chipper disc is arranged crosswisely at an acute angle to the longitudinal pathway of feed, and a feed works is provided for feeding the tree butt first to the chipper knives. The feed works includes a generally vertically disposed, fixed axis side feed roll on one side of the pathway, a generally vertically disposed swing side feed roll on the opposite side of the pathway; and a bottom feed roll disposed crosswisely to the pathway and defining the lower boundary of the pathway. A partly conical convergent chute minimizes frictional impedance and a plow is provided for moving debris from the vicinity of the feed works. The rolls are driven at coordinated speeds of rotation in a direction to feed the tree into the chipper mouth.
