US 6,662,837 B2 · Replaceable blades for wood chippers

Abstract

Single-edged wood chipper blades which can be repeatedly removed from a wood chipper and sharpened, as needed, to prevent the need for disposing of multiple conventional blades over a prolonged period of repeated use. Each of the replaceable blades typically includes a blade mount base for engaging a rotary chipping head of the chipper, a clamp plate for engaging the blade mount base, and a blade body interposed between the blade mount base and the clamp plate. A blade edge is shaped in the front end of the blade body, and extends from between the blade mount base and the clamp plate. A blade babbitt is provided in the rear end of the blade body. Accordingly, the blade body can easily and repeatedly be removed from between the blade mount base and the clamp plate and sharpened, and again secured in place between the blade mount base and the clamp plate, as needed for optimum and economical operation of the chipper over a prolonged period.
