- B. Prior Art
- The Brandli et al. Patent (U.S. Pat. No. 3,895,463) discloses an apparatus for buffing and polishing the entire outer surface of cylindrical tubing. However, this patent is not portable, and does not utilize a sanding belt that is draped over the exterior surface of a cylindrical object. This patent also uses pneumatic circuits and hydraulic motors to transmit power to the moving parts.
- The Gardner Patent (U.S. Pat. No. 5,038,525) discloses a pipe and polishing apparatus and method which comprises a cradle having an open section and a pair of pivotable doors covering the open sections and adapted to move between an open, pipe receiving position and a closed, pipe polishing position, the doors biased to remain in an open, pipe receiving position. This patent does not utilize a sanding belt that is draped over the exterior surface of a cylindrical object with a housing that contains an electrical motor, as opposed to a device that attaches to the chuck of a standard drill.
- The Kadinger Patent (U.S. Pat. No. 6,813,797) discloses an adjustable wire brush tool for cleaning either the inside or the outside end of a copper pipe. This device attaches to the chuck of a standard drill, and is not expandable to accommodate the various diameters of cylindrical objects.

- The Burrell Patent (U.S. Pat. No. 4,869,026) discloses a belt sander which is powered by an electric motor and polishes metal or wood work pieces to a cylindrical or curved shape. However, this patent requires an exterior motor to provide the mechanical means to rotate the sanding belt.
- The Helbig Patent (U.S. Pat. No. 2,759,305) discloses a portable polishing and abrading machine that is not designed to drape a sanding belt over the exterior surface of a cylindrical object.
- The Tomo et al. Patent (U.S. Pat. No. Des. 228,616) illustrates a design for a portable polishing device that is not directed to sanding and does not drape a sanding belt over the exterior surface of a cylindrical object.
- The present invention relates to a hand-held motorized device that is designed for sanding cylindrical objects. The invention comprises a left side and right side within which are a plurality of rollers, a motor, an on/off button, power supply, and sanding belt. A plurality of diameter knobs located on the exterior side of the housing enable a range of adjustment for various diameters. The sides can be disassembled to enable sanding-belt replacement.
- The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention:
- In the drawings:
-
FIG. 1 illustrates an isometric view of the invention; -
FIG. 2 illustrates a cross-sectional view of the invention along line 2-2; -
FIG. 3 illustrates a cross-sectional view of the invention along line 3-3; and -
FIG. 4 illustrates an isometric view of the invention in use. - Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in
FIGS. 1-4 . Theinvention 10 comprises ahousing 15, which is comprised of aleft side 16 and aright side 17. The housing has the shape of a half oval. Theleft side 16 andright side 17 are connected by a plurality offasteners 18, which comprise screws, rivets, and bolts. Container within thehousing 15 is amotor 20, which is held in place by theleft side 16 andright side 17. A plurality ofguide rollers 21 are strategically located within thehousing 15, and are held in place by theleft side 16 andright side 17. - Connected to the
motor 20 by awire 22 is an on/offbutton 23, which in turn is connected by awire 24 to abattery pack 25. It shall be noted that an alternative power source for the invention may be in the form of a transformer and power cord, which are not depicted in the Figures. - Located near the top interior of the
housing 15 is a plurality ofrollers 21 that are adjustable by adiameter adjustment knob 26. Asanding belt 30 is placed within the housing and travels around therollers 21 andmotor 20, and exits thehousing 15. Thesanding belt 30 has its sanding side located on the interior of the belt so that when placed around apipe 40 it sands the exterior of thepipe 40. Thediameter adjustment knob 26 has an end that protrudes through thehousing 15, and enables the end user to adjust the diameter of thesanding belt 30. - The
invention 10 is placed over an end of thepipe 40 and the on/offbutton 23 is depressed powering theinvention 10. The end user then pulls on theinvention 10, which forces thesanding belt 30 to engage thepipe 40. The end user continues operation until the material is sanded or polished to the desired level. Thereafter, the end user disengages the sanding belt from the pipe and turns theinvention 10 off. - To replace the
sanding belt 30, thefasteners 18 have to be removed and theleft side 16 andright side 17 disconnected so as to expose the interior of thehousing 15. Once the interior of thehousing 15 is exposed, the sandingbelt 30 can be removed and replaced. After the sandingbelt 30 is replaced, the left side 16-andright side 17 are aligned and connected by attaching thefasteners 18. - The
invention 10 can accommodate a wide range of sandingbelts 30 that come in various grits. The housing can be scaled to a larger or smaller size so as to accommodate different ranges of pipes.
