  • This invention relates to a shampooer with foamgenerating means. More particulary, the invention is directed to a shampooer for the nap surfaces of carpets and the like and wherein a liquid detergent shampoo material is applied to the nap surface in the form of foam.
  • the present invention is directed to an improvement over the device of said US. Pat. No. 3,602,933, wherein the crank mechanism and vibratory forces due to the crank and reciprocating brush are eliminated.
  • the device is less costly to manufacture and yet provides excellent high speed generation of a relatively dry foam, due to improved distribution of shampoo liquid before it is transformed to foam.
  • a freely rotatable open cell sponge-like roller is disposed below the usual distributor for receiving shampoo in liquid form.
  • a driven rotary brush is disposed adjacent the roller, with the brush bristles impinging upon and squeezing the roller to transform the shampoo from liquid to foam.
  • the foam is carried by the brush to the nap surface and is worked into the nap by the brush.
  • FIG. 1 is a perspective view of a device constructed in accordance with the invention
  • FIG. 2 is a front end elevation of the device, with parts removed, broken away and in section;
  • FIG. 3 is a longitudinal section through the device taken on line 3-3 of FIG. 2.
  • the invention is embodied in a device for shampooing carpets and the like, which generally includes a manually operable handle 1, a liquid shampoo tank 2 secured to handle 1 and a framelike lower housing 3. Housing 3 includes an upper cover 4 and a lower platform-like portion 5.
  • the shampooer is supported for reciprocating movement over the floor surface 6 by means which in this embodiment comprise a pair of rotatable rollers 7, which also may assist in working shampoo into the nap.
  • Rollers 7 may be of any suitable construction, such as relatively rigid grooved plastic, and are suitably journaled beneath housing portion 5.
  • the device includes a shampoo liquid supply means which includes tank 2 which connects through a conduit 8 to an elongated liquid distributor 9 secured to housing portion 5.
  • Distributor 9 is provided with the usual series of openings 10 for liquid to pass downwardly through. Suitable well-known means, now shown, may be utilized for controlling flow of liquid shampoo from tank 2 to distributor 9.
  • Liquid passing through openings 10 is first converted to foam above surface 6 and then applied to said surface.
  • an elongated roller 11 of polyurethane or other suitable compressible sponge-like open-cell material is disposed below distributor 9 and is parallel thereto and generally co-extensive therewith.
  • Roller 11 is mounted for free rotation on housing portion 5, as by end bearings 12, for purposes to be described; and is adapted to receive shampoo in liquid form which drips down through openings 10.
  • an elongated rotatable brush member 13 is disposed adjacent and in par allelism with roller 11 and with its axis disposed slightly downwardly and to one side of the roller axis.
  • Member 13 is generally co-extensive with roller 11 and comprises a core 14 mounted on housing 5, as by end bearings l5, and a plurality of rows of brushes 16 secured to the core. As shown, the tufts of brushes 16 are mounted generally tangential to the surface of core 14, and are in helical rows.
  • the length of brushes 16 is such that they compressibly overlap the peripheral portion of roller 11. In other words, the combined radii of roller 11 and element 13 is greater than the distance between their axes.
  • Member 13 is rotatably driven by a motor 17 via a connecting belt 18.
  • Motor 17 is mounted on housing portion 5 and is preferably designed to drive member 13 at about 600-700 r.p.m.
  • the shampoo liquid dropping down onto roller 11 through openings 10 might tend to spread unevenly through the roller, if it was fixed. Therefore, as brushes 16 rotationally impinge on roller 11, they will cause the latter to spin in response thereto. The centrifugal force caused thereby will create a more even distribution of liquid in the roller and the liquid will be concentrated in the peripheral area contacted by brushes 16. This prevents roller 11 from becoming overloaded with unusable shampoo. In addition, the cooperative spinning of brush member 13 and roller 11 reduces friction therebetween to a minimum, thus substantially reducing wear.
  • Brush member 13 may rotate in either direction with equally good results.
  • a liquid distributor b. means to supply liquid shampoo to said distributor,
  • a device for applying liquid shampoo in the form of foam to a nap surface comprising:
  • a liquid distributor b. means to supply liquid shampoo to said distributor,
  • a rotatable brush disposed adjacent said roller and with said brush having rows of bristles compressibly overlapping the peripheral portion of said roller
  • liquid concentrating means comprises: means mounting said roller for free rotation thereof in response to rotation of said brush so that centrifugal force will cause said liquid shampoo to be concentrated in said peripheral portion of said roller.
