Anti-kickback device for a wood processing machine

Abstract From the Canadian patent

The disclosure herein describes an antikickback device for use in a wood processing machine. The invention is concerned with mounting upstream of, an arrangement of circular saws a series of fingers, pivotably mounted on a shaft mounted transversely of the frame. Each finger is characterized by a curved edge, facing the lumber passing by, on which is mounted a series of peripherally spaced lumber-engaging pointed elements, each element defining a different angle with respect to the pivot axis of its shaft. Each lumber-engaging element consists of a support which is removably mounted to the curved edge and a blade preferably made of carbide material, fixed to this support.
