  • Patent number: 6615701
    Abstract: A cutting device, such as a beveling miter saw, includes a base, a work table supported on the base, and a cutting unit operably connected to the base. The work table includes a workpiece support surface and a stop portion. The cutting unit is selectively rotatable about a first axis between leftward and rightward bevel positions relative to the workpiece support surface. A rotatable stop member is coupled to the cutting unit and is selectively rotatable relative to the cutting unit to selectively contact the stop portion to thereby prevent rotation of the cutting unit in one direction about the first axis. The rotatable stop member and the stop portion may be positioned so that those elements contact when the cutting unit is at a predetermined bevel position, such as a vertical (0°) bevel position, relative to the workpiece support surface.

  • Patent number: 6510772
    Abstract: Apparatus includes a first member and a second member. The first member includes a first surface and the second member includes a driven member. The second member is movable relative to said first member between a first position and a second position, wherein the driven member is closer to the first surface in the second position than in the first position. The second member includes an inlet, an outlet, and an enclosed pathway between the inlet and the outlet. A collector is movably coupled to the second member at the inlet and communicates with the inlet.
