摘要： A final filter is provided for cleaning the cooling air drawn into the motor driven pump of a vacuum cleaner featuring a centrifugal separator. The final filter comprises a large area foam block filter and a sheet filter element received in a filter tray which is slideably received in a filter plenum disposed between the centrifugal separator and the motor/pump combination of the vacuum cleaner. The filter tray is supported horizontally within the filter plenum to define an inlet manifold and an outlet manifold having optimum flow characteristics and a detent is provided for snap locking the slideable filter tray within the filter plenum.

摘要： An extractor having a cleaning solution line which extends from the solution tank to a non-self-priming pump and to the normally closed valve which controls the flow of liquid on to the cleaning head. The extractor uses a manually operated priming pump to draw cleaning solution from the solution tank through the cleaning solution line to the non-self-priming pump. Following activation of the manually operated priming pump, a check valve directs the cleaning solution to the operating non-self-priming pump to effect priming of said pump. Solution is then controlably pumped past the fluid flow control valve to the cleaning head. The check valve remains open while the pump is in operation.

摘要： A vacuum cleaner is provided with a suction nozzle and a cylindrical rotary brush. The brush includes a plurality of generally longitudinally extending rows of uniform bristle tufts. Alternate tufts in alternate rows are spaced at about twice the distance as the remaining more closely spaced tufts and prepare the carpet for sweeping by the latter.PRIOR ART OF INTERESTU.S. Pat. Nos. 1,044,488, Case, 11/19/12; 1,970,355, Bennet, 8/14/34; 2,281,798, Prince, 5/5/42; 2,459,007, Taylor, 1/11/49; 2,659,921, Osborn, 11/24/53; 3,716,889, Goldstein, 2/20/73; 3,815,170, Brooks et al, 6/11/74.BACKGROUND OF THE INVENTIONVacuum cleaners have long been considered one of the most effecient devices for removing debris from carpets and the like. Many modern cleaners, when of the upright type, often comprise a power head portion having a vacuum nozzle, a rotary brush in the nozzle for engaging the carpet, and a brush drive motor; as well as an upright handle or stick pivoted to the head and including a suction motor and a storage chamber for receiving the material removed from the carpet.The rotary brush has usually comprised a cylindrical core having rows of brush bristle tufts. In many prior constructions, the tufts were arranged longitudinally along the core surface in straight or spiral rows, with adjacent tufts being close together and equally spaced.Various attempts have been made over the years to improve the ability of the rotary brush to loosen debris on the surface and deep within the carpet so that the material may be readily sucked through the nozzle into the storage means. For example, in the above-mentioned Prince U.S. Pat. No. 2,281,798, a rigid beater bar is used in conjunction with the brush row. In Taylor U.S. Pat. No. 2,459,007, it is suggested to provide alternate rows of short stiff tufts and long flexible tufts. In Osborn U.S. Pat. No. 2,659,921, it is suggested to use three rows of brush bristle tufts, each of a different stiffness. In Goldstein U.S. Pat. No. 3,716,889 it is suggested to provide alternate "agitator elements" in each row, with alternate rigid and resilient elements.It is readily apparent that all of these "improved" brushes are subject to the disadvantage of increased cost of manufacture, as compared with the aforementioned rotary brush wherein all the rows comprise identical equally spaced tufts of the same length. It is expensive to provide multiple types of tufts or other agitator elements in the same brush and has required special tufting machinery and/or multiple passes through a single machine. Furthermore, rigid agitator elements or beater bars subject the carpet to undesirable wear.SUMMARY OF THE INVENTIONThe present invention solves the aforementioned problems, and is based on the very surprising discovery that complete removal of alternate tufts from alternate tuft rows in a brush wherein the tufts are otherwise all uniform provides a substantially increased cleaning efficiency in a vacuum cleaner of the type indicated. Such a result was wholly unexpected since the normal expectation was the opposite, that is, if bristle tufts were removed from a brush, the brush would not perform as well.While the present inventors' solution to the aforementioned problems may seem simple in retrospect, it nevertheless has created an improved cleaning concept using a low cost brush which subjects the carpet to less wear.

摘要： A wet vacuum/extractor having a first cleaning solution line which extends from a cleaning solution tank to a non-self-priming pump and a second cleaning solution line which extends from the pump to a normally closed fluid flow control valve which controls the flow of liquid on to the cleaning head. The vacuum priming system of the present invention opens the second cleaning solution line to the vacuum generated between the cleaning head and the vacuum fan. This vacuum beyond the output of the pump draws solution from the solution tank into the operating pump. Once the pump is thus primed, the second cleaning solution line is closed to the vacuum and the pump now pumps the solution past the closed fluid flow control valve to the cleaning head.

摘要： The present invention is a surface cleaning liquid extractor for vacuum cleaning a surface. The extractor has an open top recovery tank, a housing which seats upon the recovery tank and a convenient carrying handle which latches the housing and the recovery tank together. The extractor also has a floating splash damper positioned within the recovery tank for floating upon the surface of liquid collected in the tank to minimize splashing of the liquid. The top surface of the floating splash damper includes a domed portion for engaging the suction opening of the extractor and sealing off the suction from the recovery tank when the recovery tank has filled with liquid.

摘要： A dry rotary shaver having a floating shear plate which is supported beneath its periphery by resilient spring means. The spring support is fixed within the shaver head, prevents shear plate rotation, and acts as a means to retain the shear plate and rotary cutting element in place when the shaver head is removed from the shaver housing. Furthermore, the spring support may incorporate stop means to prevent hang up of the shear plate on the shaver opening in the event the shear plate is forceably pressed inwardly, as by a finger.

摘要： A floor sweeper having, in addition to its main brush roller, one or more auxiliary brushes for sweeping debris into the path of the main brush. Each auxiliary brush includes a brush body having an annular array of outwardly downwardly inclined brush bristles. A flexible drive ring is mounted concentric to said bristles and adjacent the roots thereof on the underside of the brush body. Both the ring and bristle tips are disposed in fixed parallel planes and the assembly is mounted on an axis which is fixed and inclined from the vertical in a manner so that the rearward brush edge will, upon forward sweeper movement, rotate transversely inwardly beneath the sweeper housing with a debris disturbing and flicking action. Downward force on the sweeper causes the drive ring to deform upwardly and to deflect the adjacent bristles in a direction away from the carpet to keep the brush-carpet friction forces generally equalized.

摘要： A vacuum extractor has a tank assembly including an outer tank and a coaxial inner tank. The inner tank has an open top which is reversibly closed by a cover assembly which includes a vacuum source and a liquid pump. The cover assembly also includes a hose connection in communication with said inner tank and said vacuum source enabling said inner tank to receive either wet or dry materials. The outer tank is substantially closed having an input port closed by a closure member configured in the form of a measuring cup. The outer tank is used for containing a cleaning material which can be accessed through a hose which passes through an aperture in the outer wall of the tank. The hose has an external connector for supplying cleaning material to the liquid pump in the cover assembly which, in turn, supplies the cleaning material to a cleaning tool. The unit is supported by casters which are recessed into the bottom of the tank assembly. A pair of opposed caster recesses are shaped to provide handholds to assist in emptying the separate tanks. The inner tank can be emptied by pouring in a first direction while both inner and outer tanks can be emptied simultaneously by pouring in a second direction opposite to the first direction.
