Abstract:
1. A clamping assembly for clamping one or more knife elements onto a woodworking machine, said clamping assembly including: a clamping component comprising a body having two ends and opposed sides, said body being sized and shaped to have three discrete contact positions distributed on said body, said three discrete contact positions comprising a surface defining a fulcrum located generally at one end of the body, a surface defining a knife abutting portion located generally at the other end of the body for abutting said one or more knife elements, and a bearing surface located on said body separate from said fulcrum and between the fulcrum and the knife abutting portion; said surfaces defining said fulcrum and said knife abutting portion being located on the same side of said body and an actuator for applying a clamping force to said body along a clamping axis located intermediate of said knife abutting portion and said fulcrum; said fulcrum being formed as a substantially planar surface wherein a line normal to said fulcrum is at an acute angle ⊖ to said clamping axis; said bearing surface being formed as a substantially planar surface positioned on said body such that a line normal to said bearing surface intersects said line normal to said fulcrum at a position outside of said clamping component at a location farther askew of said clamping axis than said fulcrum, whereby the fulcrum and bearing surface support the clamping component against the clamping force applied by the actuator and the reaction forces at the fulcrum and bearing surface oppose the clamping force.
