Improved insert teeth and holder assemblies are provided for a material breaker machine intended for use in reducing chunks or pieces of wood, metal and other materials to small size. The present invention includes an insert tooth member having a pair of edges, either of which may serve as a cutting edge. An insert tooth holder is provided for mounting of the insert tooth. The insert tooth and insert holder interengage through a raised portion on the one and a recessed portion on the other which mate to form a positive mechanical lock. The insert tooth is reversibly mounted on the insert holder to allow either of the pair of edges to assume the position of the cutting edge. The location of the interengaged components allows them to be fully protected from the material being cut, thus minimizing wear and damage. In one embodiment, the insert tooth is inclined at an angle with respect to the insert holder, thus providing relief against back-up of material being processed and allowing the material to feed more quickly.

A rotor assembly for a shavings making machine having a plurality of knife and wedge assemblies is disclosed. The knife and wedge assemblies are removably mounted in channels or pockets extending parallel to the rotor axis along the length of the circumference of the rotor. In mounting each knife and wedge assembly to the rotor, the knife insert is first mounted on the respective wedge insert and the wedge insert is then mounted on the rotor. The bolts or other means for mounting each knife insert on the wedge insert are located below the periphery of the rotor and adjacent one side wall of the respective channel such that the bolts cannot back out or become loosened due to vibrational forces. Each knife insert has two reversible blades which are symmetrical. A flattened surface on the rotor adjacent each knife insert assists in providing an effective cutting operation.

An improved pivot pin which allows individual pin connection of each hammer in the rotor of a shredder is disclosed. The pivot pin includes male and female pin members which interengage in a tight fit so as to function as a single pin when fitted together. A bore extends through both of the male and female pin members, with the bore through the female pin member being threaded. A securing device such as a socket head capscrew passes through the male pin member from the outer to the inner end portion thereof and is threadedly received in the female pin member.
