Abstract: The claimed carpet cleaning apparatus incorporates recesses in a rigid surface of a roller, a hand-operated cleaning device, or a rigid disk. The rigid surface compresses the fibers of the soft surface as the device and the recesses decompress the fibers. The repeated compression and decompression, preferably in combination with a cleaning compound, provide the mechanical action necessary for removal of foreign material.

Abstract: The claimed carpet cleaning apparatus incorporates recesses in a rigid surface of a roller or in a rigid disk. As the roller or disk rotates or is moved across the soft surface to be cleaned, the roller or disk presses downward on the soft surface and compresses it. The soft surface decompresses to the original position when the soft surface is in contact with a surface of a recess and recompresses when the roller or disk presses downward again. The compression, decompression, and recompression, preferably in combination with a cleaning compound, provide the mechanical action necessary for removal of foreign material.

Abstract: The push brush carpet or hard surface cleaner of the present invention is preferably comprised of a cleaning brush with a round surface area to which cleaning bristles of any conventional size and shape are attached. In practice the brush is preferably pushed over the carpet or hard surface to agitate and/or expel a debris-laden cleaning solution that has been previously applied to the carpet or hard surface to accomplish cleaning. The cleaning solution can be any conventional chemical solution suitable for the purpose of carpet or hard surface cleaning, but the brush of the present invention is preferably used in conjunction with a dry powder or substantially neutral pH dry crystalline formula cleaning solution for carpets. Finally, the optional axle, bearing and wheel configuration permits easy disassembly of the brush to allow easy replacement of the brush and to permit accommodation of various brush sizes and bristle varieties.

Abstract: The push brush carpet or hard surface cleaner of the present invention is preferably comprised of a cleaning brush with a round surface area to which cleaning bristles of any conventional size and shape are attached. The brush is preferably attached to a frame by use of an axle, wheel and bearing configuration which permits locking of the axle in place at a given rotary position of the brush and also unlocking of the axle to permit rotation of the brush to a different position. In use, the rotary brush is locked in place in a given rotary position by the user, and a portion of the brush surface will come in contact with the carpet or hard surface as the user pushes the brush in a preferably reciprocating motion. In so doing, debris on the carpet or hard surface is agitated and/or expelled by the contacted area of the brush surface.

Abstract: A dispenser for powder or granular material which has a hopper for containing the material to be dispensed. The hopper includes an arcuate bottom member having a plurality of discharge openings. A wiper is positioned along the length of the bottom member and mounted to a rotatable shaft. The wiper includes a plurality of wiper elements mounted to the shaft each having at least one radially extending blade. The radial extent of each blade is sufficient to contact the openings during rotation of the shaft. Adjacent blades are mounted so as to be offset from each other. A drive is provided to rotate the shaft.
