  • Publication number: 20100197212
    Abstract: A device for chamfering and sanding is disclosed. The device comprises a cylindrical body containing a hollow cone lined with sandpaper attached to the surface of the cone with adhesive. Two corners of the sandpaper are inserted respectively into two slots contained in the sidewall of the cone to further hold the sandpaper in place. The device comprises a shaft attached to the bottom of the device for clutching by a drill press or a three jaw chuck. As the device rotates, objects that require bevelling or sanding are inserted into the cone and pressed against the sandpaper. A sandpaper sleeve is attached to the outer surface of the cylindrical body that may be used for sanding and smoothing.

  • Patent number: 7223160
    Abstract: A system for rapid replacement of abrasive in machinery which uses the abrasive to finish the surfaces of workpieces that pass through the machinery on a belt, such as so-called widebelt sanders. One preferred embodiment of the system employs an abrasive material that is frictionally held on each edge to mounts. The position of the mounts may be varied to increase or decrease the tension of abrasive material against the working surface of the platen, that the assembly may be removed from the apparatus. In another embodiment, the abrasive material is formed with integral, permanent mounts on the edges of the abrasive material, so that the entire combination may be supplied or replaced as a unit. A variety of configurations of mounts may be used.

  • Patent number: 6626747
    Abstract: The invention is directed to an improved abrasive pad (15). In the preferred embodiment, the abrasive pad is comprised of an inner core (16) having an outer surface (19), a strip of abrasive material (18), the strip of abrasive material wrapped around the outer surface of the inner core, and a central throughbore (20) extending through the material and the inner core and adapted for engagement with a torque-producing device. The outer surface of the abrasive pad may comprise a top surface (21), a bottom surface (22), a front surface (23), a rear surface (24), a right surface (25), and a left surface (26), and the abrasive strip may be wrapped over the right surface, the bottom surface, the left surface, and the top surface to form a first layer (28) of abrasive material. The abrasive strip may be wrapped around the inner core at least twice to form at least a second layer (29) of abrasive material. The abrasive material may be sandpaper and the throughbore may be threaded (35) for engagement with a mandrel.

  • Patent number: 6500060
    Abstract: A rotary polishing disc for dental grinding and polishing includes a disc-shaped piece of sheet of abrasive material fixed to a hub. In one embodiment, the hub is a hollow cylinder which is received onto a rotatable arbor. In another embodiment, the hub has a first end fixed to the sheet material, and has a second end that is received by a socketed end of the arbor. To fix the disc-shaped piece of sheet material more securely to the hub, a retainer plug may pass through a central aperture in the sheet material and enter into the hub. The retainer plug has a flat cap which becomes juxtaposed with the sheet material furthest from the hub. In another aspect, an improved arbor for the first type of hub includes protruding barbs which spear the hub when its hollow interior is disposed on the arbor.

  • Patent number: 5643063
    Abstract: A carrier is connected to the plunger for reciprocating therewith; the carrier is of inverted U-shape defining a recess open at its bottom. A holder is pivotally mounted to the carrier for swinging movement back and forth between a first position wherein the holder is substantially nested within the recess in the carrier and a second position wherein a substantial portion of the holder extends out of and away from the carrier recess. The holder is also of inverted U-shape defining a cavity for receiving a portion of a contour sanding member. Detent elements on the carrier compress the holder when the latter is in its first position thereby to impart a clamping force to a contour sanding member received within the cavity of the holder. A manually operated ejection member mounted on the tool housing engages the holder for moving the same from its first position to its second position.
