  • Patent number: 7189152
    Abstract: A height adjustment mechanism for varying the positioning of a rotating tool on a haft of a machine tool, such as a portable power tool, is in the form of a coupler between the blade and tool arbor. A head of the coupler accepts the tool and connects with a tool drive, the depth of the connection defining the working height or position of the tool. A pair of inter-engaged flanges are mounted upon the shaft of the coupler head, and apply forces to the coupler head and tool drive to maintain the connection depth therebetween and to retain the tool in position. A jam nut further maintains the relative orientation of the flanges.

  • Patent number: 6802765
    Abstract: A tool for resurfacing the area surrounding a protruding stud, without removing the stud from the member to which it is attached, includes a quick connect/disconnect coupler at one end thereof for attachment to and removal from a conventional rotary power tool. A central longitudinal aperture in the tool opens to a distal end thereof, and an abrasive surface preparation disc having a corresponding central aperture is adapted for removable attachment to the distal end of the tool. The tool is positioned over the stud such that the stud extends into the central aperture of the tool and the surface preparation disc is in contact with the surface area surrounding the stud. Controlled rotation of the tool in place over the stud results in a desired degree of uniform abrasion of the surface area surrounding the stud.

  • Patent number: 6659852
    Abstract: An improved sanding block for sanding high and extended surfaces configured for use in combination with an attached pole. The sanding block is round in shape and is rotationally mounted on a pole mount that interfaces between the sanding block and the pole which attaches to a rotatable hub of the pole mount. This allows the sanding block to rotate during use and the pole to be rotated to different angles in relation to the flat working surface of the sanding block. Adjacent surface marring is prevented by the rotation of the sanding block upon contact of a side edge with such an adjacent surface. Optionally the pole mount can be locked to prevent rotation if desired and a barrel can provide an interface between the pole and the pole mount. This barrel can be straight, angled, or adjustable for angle, in the different preferred embodiments.
