  • In-line sander
    Patent number: 6257969
    Abstract: An in-line sander comprising a sander body which houses a motor coupled to an in-line oscillating mechanism. The in-line oscillating mechanism is adapted and configured to move a sanding pad in a linear oscillating motion. A corner or detail pad has a substantially flat lower surface and a substantially pointed front portion bounded laterally by two substantially-linear corner-sanding edges having an included angle of less than 90 degrees. A forward end of this substantially pointed front portion of the preferred corner or detail pad protrudes ahead of a front end of the sander body throughout the linear oscillating motion of the pad. The front portion of the preferred corner or detail pad has particular application for sanding into corners of a carcass.

  • Motorized rotary tool having a head mounted by a pivotal joint
    Patent number: 5690545
    Abstract: A motorized rotary tool having a drive motor mounted on a distal end of a tubular wand is provided. A drive shaft is operatively coupled to the drive motor and extends along the length of the tubular wand. A head is mounted by a pivotal joint to a proximal end of the tubular wand. The head includes a rotary pad operatively coupled to the flexible drive shaft such that the rotary pad can be driven rotably by the drive shaft. The pivotal joint has a first and a second flexible joint. The first joint is configured to pivot about a first axis which is different from a second axis about which the second joint pivots.
