Abstract
Apparatus for processing logs to manufacture wood chips. The apparatus includes a circular disc for passing a series of blades through a chipping station and a chute and spout assembly for feeding logs from a conveyor into the chipping station. A lifting mechanism is mounted for rotation upon a shaft which is situated adjacent to but outside of the chute and spout assembly. A drive unit is arranged to turn the shaft so that the lifting mechanism is rotated between a retracted position outside of the flow described by the chute and spout assembly and an extended position inside the chute and spout assembly whereby the lifting mechanism can contact logs within the assembly and move the logs contra to the direction of flow.
