Patent number: 6805622Abstract: A ski sharpening arrangement includes a portable powered grinder adapted to be manipulated by one hand of a user. The arrangement includes a motor assembly spaced from a ski having a top surface, a base, a side edge and a bottom edge coplanar with the base. The motor assembly drives an endless belt having an abrasive surface about an axis of rotation transverse to a plane of the base. The endless belt is entrained about a mounting framework extending from the motor assembly, and engaged against the side edge of the ski to provide sharpening thereof. A support structure is suspended from the mounting framework of the belt and is adapted to be manipulated by another hand of the user for guiding, stabilizing and changing the angle of the abrasive surface relative to the side edge of the ski.Type: GrantFiled: March 11, 2003Date of Patent: October 19, 2004Inventor: Wolfgang C.

Patent number: 6769974Abstract: A sand-belt finishing machine having a sand-belt replacement mechanism includes a support rack, a first roller, a second roller, an upright rod, an elastic member, a sand belt, and a pull lever. When the upright rod is moved by the pull lever to compress the elastic member, the distance between the first roller and the second roller is shortened. When the upright rod is released by the pull lever, the upright rod is returned to its original position by the elastic member, so that the distance between the first roller and the second roller is increased. Thus, the sand belt can be mounted on and detached from the first roller and the second roller rapidly, easily and conveniently, thereby facilitating the user replacing the sand belt.Type: GrantFiled: November 1, 2002Date of Patent: August 3, 2004Inventor: Wang Tien Wang

Patent number: 6503128Abstract: A grinding attachment for use in conjunction with hand-held grinding or drilling power tools such as are commonly found around the house, and method for using this attachment. The purpose of the invention is to allow the homeowner and the like to have greater facility in performing surface sanding, grinding, or finish work on pieces of wood and the like. In particular, the goal is to provide proficiency in working with surfaces that are not planar or otherwise simple. By providing an appropriate compound support against which an abrasive belt or the like is to run as it works the surface, it is possible to have a variety of backing shapes ranging from a strictly planar backing to one that allows the abrasive material to take the shape of whatever piece is being pressed against it. The invention derives its motive power from a coupling to a power tool, typically by the insertion of a drive axle of the attachment into the chuck of a hand drill.Type: GrantFiled: June 7, 2000Date of Patent: January 7, 2003Inventors: William R. Deware, William L. Andrews

Patent number: 5545077Abstract: A band sander has a motor housing (2) and a band running case (17) located below the latter, the abrasive band revolving therein. The abrasive band is driven via a belt (17) and belt wheels (14, 16).
