Patent number: 7814613Abstract: 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.Type: GrantFiled: November 6, 2009Date of Patent: October 19, 2010Assignee: R.E.

Patent number: 7159276Abstract: Catching grooves (34) extending in the axial direction are formed in the cylindrical outer surface of a brush base (35) that has a slender, substantially cylindrical shape and made of a twistable material. Brush attaching portions (43) of brush members (41) and blade attaching portions (47) of scraping members (42) are respectively secured in the catching grooves (34) so that axially aligned bristles (44) of each brush member (41) and an axially extending blade (46) of each scraping member (42) project from the cylindrical outer surface of the brush base (35). Receiving members (53) are respectively fitted to both ends of a shaft (51) inserted through a shaft insertion hole (39) of the brush base (35). By rotating the receiving members (53) in opposite directions, the brush base (35) is twisted in a spiral and secured. By eliminating the necessity of forming the brush base (35) in a twisted shape beforehand by means of twist extrusion molding, the invention facilitates production of the brush base (35).Type: GrantFiled: May 18, 2005Date of Patent: January 9, 2007Assignee: Toshiba Tec Kabushiki KaishaInventors: Shuhei Omoto, Yasuhiro Ohtsu

Patent number: 6244947Abstract: Accessories for an angle grinder include a rotary disk tool having a working zone around the periphery of the disk comprising a plurality of wire bristles and a rest means for supporting the grinder on a surface to be shaped. The rest means may be a non-rotating nose beneath the grinder, a rubbing contact mounted on a flat tool or simply the central part of a convex tool Tilting the grinder about the rest means gives effective control of the tool. Steeper tilts cause the cutting surface to bite more deeply into the work. The grinder is stroked toward the user with the cutting zone 2206 trailing. Most disks are perforated. Work to be shaped can be seen through the spinning disk during use. A tool base onto which a variety of cutting surfaces can be affixed is also provided, and a type of wire brush attachment incorporating a rubbing contact is provided.Type: GrantFiled: May 20, 1998Date of Patent: June 12, 2001Assignee: Norton CompanyInventor: Anthony Alfred Van Osenbruggen
