  • Patent number: 10245751
    Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.

  • Patent number: 7681609
    Abstract: A wood working knife for use in a wood working machine, comprising a knife body having a first cutting edge and an opposed second cutting edge, the knife body having a first clamping surface and a second clamping surface. The first clamping surface has opposed clamping features separated by a middle section, the opposed clamping features and the middle section being sized and shaped such that, upon the knife body being inserted into a clamping assembly, the clamping forces are localized towards the opposed cutting edges and away from the middle section.

  • Patent number: 6058989
    Abstract: A self aligning knife clamping assembly and machine incorporating the same are disclosed. In one embodiment there is provided a knife clamping assembly having an upper clamping component, a lower clamping component and a fastening device, such as a bolt, therebetween, to permit the clamping components to be releasably clamped together onto a knife element having a knife edge. Positioned between the knife element and the clamping assembly is a biasing element, which urges the knife element to enter, or remain in, a preferred position prior to the knife element being immovably clamped into place. In the preferred embodiment the biasing element is in the form of an elastomeric strip.
