Abstract: A riding apparatus for treating a floor surface has a main steering and drive wheels and a forwardly located seat for an operator and at least one foot rest for feet of the operator. The vehicle has a polishing and cleaning deck mounted in front of the vehicle and is operably connected to the main vehicle. A clearance gap is formed between the vehicle and the polishing and cleaning deck. The at least one foot rest has a gap therebetween for providing a line of sight for the operator through the gap to view the floor surface directly behind the deck.

Abstract: An edger machine for treating a floor and other surfaces has a housing with a motor and a deck. The motor has a drive shaft extending into an upper deck section of the deck. A pulley is positioned forward of the drive shaft, and a drive belt connects the drive shaft to the pulley. The pulley is constructed to mount a resurfacing disc in a lower deck section of the deck. A pair of guide wheels is mounted on an upper surface of the lower deck section adjacent the upper deck section. The guide wheels are rotatable about a vertical axis and positioned such that the wheels can roll against a vertical surface.

Abstract: A floor finishing machine includes a base frame, a movable frame movably mounted to the base frame, and a plurality of floor finishing units carried by the movable frame, and being pivotable about a generally longitudinal pivot axis and a generally transverse pivot axis. The machine may also include a jack operatively coupled between the base frame and the movable frame, and a vacuum tank carried on the movable frame and straddling the jack.

Abstract: A floor finishing apparatus includes a chassis, a housing pivotably mounted to the chassis and having a mounting surface and at least partially defining a chamber, and a plurality of floor finishing units mounted to the mounting surface of the housing. The apparatus may include a rolling device carried by the housing and adapted to contact the ground to assist the housing in being pivoted with respect to the chassis.

Abstract: A swing arm for managing a power cord to an electric vehicle has a proximate arm member with a pivotable connection about a vertical axis for connection to the vehicle in proximity to a longitudinal center line of the vehicle. A distal arm member is pivotably connected about a pivot vertical axis to the proximate arm member and resiliently biased to extend straight out with respect to the proximate arm member. The swing arm is dimensioned to extend the distal arm member beyond a side of the vehicle when the swing arm extends laterally with respect to the vehicle. A spring member is connected to the distal arm member for resiliently biasing the distal arm member to extend straight out with respect to the proximate arm member against a side force below a predetermined amount and yieldable to bending of the distal arm member upon exertion of a side force above the predetermined amount.

Abstract: A floor edger and grinding device 10 has a deck 20 pivotably mounted to a rear frame 18 with a handle 16. The deck has a motor 22 mounted thereon that drives two grinder discs 24 in opposite rotational directions. The deck has a skirt 26 and a notch 28 extending along the front edge 27 of the skirt. The discs 24 protrude into the notch 28. A case 50 surrounds the drive gears 38 for protection against dust created by the discs 24.

Abstract: A power sanding machine (10) has three circumferentially spaced cogged belts (40) to drive three discs (52) rotatably mounted to an inner bowl (30) which is rotatably mounted to a housing (12), which in turn is connected to an operating handle (14). Mechanical lock can rotationally affix the inner bowl (30) to the housing to circumferentially position a pulley at the left or right edge (326, 322) of the sanding machine or at the front end (330) of the sanding machine. Power cleaning and sanding machines (412, 500, 600) incorporate the three disc (52) arrangement or a direct-drive one disc arrangement (572, 672). The machines (412, 500, 600) include multiple floor finishing units (420, 514, 614) ganged together in unique arrangements.

Abstract: An abrasive sandpaper system having a backing plate (16) with a canted outer periphery (28) and an off-centered aperture (26) for interlocking with lugs (18) of a power driver (12). The sandpaper (30) has a canted outer periphery (38) for riding over raised edges (45) of an uneven wood deck. The backing plate may have a pocket (50) with a side wall (60) to receive the substrate layer (58) of sandpaper (54).
