Abstract: A carpet cleaning machine comprising a rotary, plastic, static accumulator, drive means for rotating the accumulator, and a pile fabric cleaning pad driven by the accumulator. Preferably the accumulator is directly connected to a nipple pad making driving connection with the rear of the cleaning pad. A bleed connection including an adjustable spark gap limits the charge which the accumulator may carry, and a safety switch discharges the accumulator when the cleaning machine is tilted to expose the accumulator or parts electrically connected thereto.

Abstract: The floor buffer includes an aluminum chassis to which the various operative elements of the floor buffer are affixed. More particularly, a buffer pad driver is journaled to the front end of the chassis and a propane tank is carried from the aft end of the chassis to which end the steering handle is affixed. An air cooled internal combustion engine is mounted to the chassis intermediate the pad driver and the fuel tank. The air cooled engine is mounted in heat exchanging relation with the chassis so that the chassis serves as a substantial heat sink for conduction cooling of the engine, in use.

Abstract: A floor finish applicator comprises a frame mounted on wheels for movement in any selected direction, a liquid finish storage tank mounted on the frame, a finish applying mechanism adapted to deliver finish from the outlet of the storage tank to the floor, and a finish spreader adapted to spread the finish out into a smooth even finish after it has been applied to the floor. The finish spreader is mounted behind the frame and is movable in a transverse direction with respect to the direction of movement of the frame. The finish spreader is resiliently biased to remain in a predetermined position but is mechanically movable in either transverse direction. A roller is provided at one or both ends of the spreader in order to provide a rolling contact between the finish spreader and the wall of a room being finished. The applicator may be used to apply any type of liquid to a floor, including waxes, varnishes, cleaners or the like.

Abstract: Buffing machine comprising rotary buffing element, internal combustion engine motor for driving the buffing element and fuel tank for liquefied gas with suitable connections to supply fuel to motor.

Abstract: An electric floor scrubber and buffer having its scrubber or buffer pad attached to the underside of an oscillating plate. A motor drive is provided for oscillating the plate which is disposed between flexible spacers extending between the plate and a stationary plate. The spacers serve to enhance the action of the oscillator plate and its underpad in performing their buffing or scrubbing functions.

Abstract: This invention relates to a roller for moving water on and simultaneously drying very large, flat hard surfaces such as tennis courts. The roller has an outer sleeve which is made from a foam whose compression load density and porosity values fall within critical ranges. The roller moves the water in the rolling direction as it simultaneously establishes a moving seal with the portion of the hard surface over which the roller rides.

Abstract: A portable wiping machine for removing water from a wet surface which may be manually moved over the surface and it includes a large drum whose cylindrical surface is perforated and covered with water absorbing material, such as a sponge. The sponge is compressed by its rolling contact over the surface and the expansion of the sponge portion as it leaves the surface will absorb the water therefrom. A sponge compressing roller is yieldingly held in contact with the top of the drum and a water receiving tray is fixedly mounted within the drum interior in a position to catch water squeezed from the sponge. A water retaining tank is supported by the machine and receives water from the tray. The tank can be emptied of water as desired.

Abstract: A floor treatment machine including a squeegee assembly having a squeegee blade adjustable for a desired angle of incidience between the blade and the floor. The squeegee assembly is pivotally mounted to a bracket for limited rotation about the longitudinal axis of the machine for tracking variations of the floor surface. The bracket to which the squeegee assembly is pivotally coupled in turn is swivel-coupled to a lifting platform by a pair of spaced support arms, each pivotally coupled between the lifting platform and the bracket to permit the squeegee assembly to follow behind the floor treatment machine as it changes direction. The lifting bracket is pivotally coupled to the machine frame and is coupled to squeegee elevating and lowering means including a compressible linkage for holding the squeegee in an operating position with a predetermined adjustable pressure of the squeegee blade against the floor surface while permitting rearward tilting of the machine with the squeegee in the operating position.
