Definitions

  • This invention relates to a sharnpooer with foam-generating means. More particularly, 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 provides an improvement over the devices mentioned above and contemplates utilization of a fixed sponge and reciprocating brush which beats against the sponge to form the desired foam.
  • the brush carries the foam thus formed to the nap surface for cleaning.
  • the construction is such that a relatively dry foam is produced.
  • 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
  • FIG. 4 is an enlarged section through the foam-generating and applying apparatus and showing the brush action.
  • 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 platformlike 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 joumaled 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 along the transverse front edge thereof.
  • Distributor 9 is provided with the usual series of openings 10 for liquid to pass downwardly through. Suitable well-known means, not shown, may be utilized for controlling flow of liquid shampoo from tank 2 to distributor 9.
  • a fixed liquid-receiving assembly .11 is disposed beneath distributor 9 and comprises an elongated resilient sponge 12 of polyurethane or other material which is secured, as by an adhesive, to an elongated relatively rigid noncellular backing strip 13 of Nylon, Teflon or the like. As shown, strip 13 is secured beneath housing portion 5, as by screws 14. In addition, strip 13 is disposed directly beneath distributor openings 10 and its upper surface 15 inclines downwardly toward a top edge of sponge 12 to form a line engagement 16 therewith, for purposes to be described.
  • a brush 17 is anchored along a backing rod 18, which in turn is suitably pivotally joumaled beneath housing portion 5 in parallelism with assembly 11.
  • Brush 17 is shown as having two rows of relatively flexible bristle tufts 19, which extend downwardly below housing portion 5 and assembly 11 for engagement with surface 6.
  • Rod 18 is shown as being disposed very closely adjacent the upper portion of the exposed front face 20 of sponge l2 and is shaped to provide an edge 21 for purposes to be described.
  • Means are provided to oscillate rod 18 to thereby reciprocate brush 17 so that it alternately engages and disengages from the sponge.
  • rod 18 is connected through a suitable arm 22, shaft 23 and crank mechanism 24 to the rotary output 25 of a motive means, such as an electric motor 26 mounted on the housing.
  • the squeezing-beating action turns shampoo liquid in the sponge into foam 27, which is carried away from sponge 12 by the brush and deposited on the nap surface thereby where the brush then proceeds to work the foam thereinto.
  • the innermost row of tufts 19 serves primarily as an additional means for working the foam into the surface, and does not participate to any major extent in foam generation.
  • the frequency of oscillation and reciprocation should be relatively high, such as 1,800 per minute.
  • Sponge 12 thus is not only squeezingly confined between the beating members and the rigid backing during engagement of tufts l9 therewith, but is provided with shampoo in such a form that the nap surface is not overwetted.
  • the shampooer provides a unique system for foam generation, and is relatively inexpensive to manufacture and maintain.
  • a device for applying liquid shampoo in the form of foam to a nap surface comprising:
  • said last-named means also serving as means to work the generated foam into the nap surface.
  • beating means (d) also comprises means for carrying generated foam from said sponge to the nap surface.
  • beating means (d) comprises:
  • beating means (d) comprises:
  • said backing having an upper surface disposed directly beneath said distributor for receiving liquid shampoo therefrom
  • a fixed sponge assembly disposed below said distributor for receiving liquid therefrom, said assembly including:
  • beating means (d) comprises:
  • said sponge backing has an upper surface disposed directly beneath said distributor for receiving liquid therefrom
  • said sponge backing surface being inclined downwardly toward said sponge to spread liquid thereover.
  • a device for applying liquid shampoo in the form of foam to a nap surface comprising:
