  • Patent number: 7757592
    Abstract: Operating a power saw between a pair of parallel guide rails, which engage opposing sides of saw base plate to constrain the motion of the saw to a straight path, allows for precise cuts. A set of two or more fences allows for multiple cutting options. In some embodiments, non-parallel fences coupled to the guide rails allow for precise cuts at more than just a single angle. In some embodiments, two fences may engage opposing sides of the object to be cut simultaneously, holding the object more securely with respect to the guide rails than would a single fence. A possible clamping force holding the two fences against the object allows the miter guide to remain fixed relative to the object so that the user's hand may be freed for another task, such as holding the saw with both hands.

    Abstract: Cutter suitable for artificial flower stems. Typically, plastic coated wire stems are cut with hand cutters to various lengths in preparing artificial floral arrangements. The invention requires far less physical effort by the operator than is required when using conventional wire cutters. In the preferred use of the preferred embodiment of the invention, an uncut stem is inserted crosswise through two elongated holes in the guard housing. When the cutter jaws open, the stem is pushed into the open jaws and is cut to a desired length from the flower end when the jaws close. In the preferred embodiment of the invention a gear reduction motor drives an arm and cam roller assembly. That cam roller forces the top handle of the cutter downward causing the jaws to close. As the cycle continues, the cam roller raises and a spring causes the jaws to open.

  • Patent number: 6991009
    Abstract: A work surface guide for portable hand-operated power tools allows their adaptation to a fixed-bed form (for example, a circular saw may be used as a radial arm saw or sliding miter saw). A pair of parallel rails are spaced laterally outwardly and above a table or other work surface so that the power tool may slide along these rails to cut matter located in a cutting area situated below and beneath the rails (and protruding from the edge of the work surface beneath the rails). A board fence is pivotally attached to one of the rails to extend onto the work surface, thereby allowing the board fence to be adjusted to some desired angle, a board to be situated against the board fence to protrude beneath the rails and into the cutting area, and the power tool to be run along the rails to cut the board.

  • Patent number: 6829830
    Abstract: A cut guide for a portable hand-held saw that has a blade with a cutting portion that is disposed along a generally vertical axis. The cut guide includes a mounting portion, which is configured to be coupled to the saw, a guide block portion, a guide portion and an adjustment mechanism. The guide block portion, which defines a generally vertical cutting stroke axis, is pivotally coupled to the mounting portion such that the cutting stroke axis can be pivoted relative to the cutting portion of the blade. The guide portion is movably coupled to the guide block portion along the cutting stroke axis. The guide portion includes an abutment structure with at least one feature for establishing an orientation of the cutting stroke axis relative to a longitudinal axis of a workpiece. The adjustment mechanism pivots the guide block portion relative to the mounting portion to thereby adjust an angular relationship of the cutting stroke axis relative to the longitudinal axis of the workpiece.

  • Publication number: 20040216574
    Abstract: The present invention relates to a device for keeping in place rolled media, while pulling the leading edge of the media, then holding the unrolled or flat media, (herein referred to as “media”) in place. The media could be made from, but is not limited to, materials such as paper, plastic, metal, or fabric. This is done while measuring a desired length from the leading edge and cutting the measured portion of the media. The invention provides a portable, safe, easy, and convenient device for handling, uncurling, sizing and cutting a desired portion of the media.
