Definitions

  • the present invention concerns an appliance for shampooing carpets or the like of the type (hereinafter referred to as of the type set forth) wherein a foam-forming :liquid detergent or like cleaning liquid is applied to the carpet.
  • this inven-tion provides that the detergent or the like is directed vof bristles substantially uniformly over the length of the brush and it is also preferred that the detergent is introduced to the bristles near the roots thereof where they are attached to a bristle-carrying member or brush stock.
  • FIG. 1 is a side view of the appliance
  • FIG. 2 is a sectional View of the lower part of the appliance of FIG. l and to a larger size
  • FIG. 3 is a part sectional View on the line III-III of FIG. 2, v
  • FIG. 4 is a section on the line yIV---IV of FIG. 2,
  • FIG. 5 is a section on the line V-V of FIG. 2, and
  • FIG. 6 is a section of the handle fitted to the appliance of FIG. 1 and to a larger size.
  • the appliance comprises a tank 1) for liquid detergent, a detergent-applying unit 11 and a tubular handle 12 secured to the. tank as later described.
  • Th/unit 11 comprises a roller 13, a pair of brushes 14 (each of which extends alongside the roller 13) a liquid guide means the form of a cover plate member 15 to overlie the roller and a duct 16 which extends along the I roller 13 and which receives the detergent delivered from the tank.
  • the appliance is moved to and fro across the surface of a carpet to be cleaned, the housewife or operator pushing and pulling on handle 12 to this end.
  • the unit 11 comprises a hollow body member 17 of such flexible material that the ends 1S thereof may be deformed and separated slightly.
  • the roller 13 and brushes 14 extend substantially between the ends 18 (see FIG. 3).
  • the roller is rotatably mounted in a chassis frame 19 as later more fully explained.
  • Each of the brushes 14 comprises a row of bristles carried by a brush stock or rib 2) which constitutes a long member of frame 19.
  • the ends of ribs 20 are secured to cross members 21 and constitute therewith the yframe 19.
  • the cover plate 15 is of inverted U-outline in crossseotion (FIG. 2) and overlies roller 13, the plate 15 extending between the ends 18 of unit 11 and being centrally beneath duct 16.
  • Plate 15 has integral end walls 22 which are removably attached to the cross members 21 (as later described in detail) so that the plate is carried by chassis frame 19.
  • the plate 15 has an upwardly-directed, central rib 63 which extends lengthwise of the plate and is immediately beneath duct 16.
  • the long edges of plate 15 are outwardly ilared (at 23, FIG. 2) and are presented to the bristles substantially at right angles to the bristles.
  • the ared edges 23 touch tbe bristles in the region of the bristle roots immediately beneath ribs 2li.
  • Tank 1l has a bottom 24 the underface of which carries duct 16.
  • Bottom 24 has an integral tubular socket 25 which passes through bottom 24.
  • Socket 25 receives the lower end of tubular handle 12, the handle being secured therein by as crew 26.
  • the socket 25 has a diaphragm which is formed with a valve seat 2S to receive a valve 2i?.
  • the latter is mounted on a wire 30 which extends through the handle, the lower end of wire 3l) having a head 31 to engage a washer 32 which abuts valve y 21.
  • a cup member 33 abuts the -upper end of valve 29.
  • a spring 34 is received within member 33 toextend between the cup and a disc 35 that is held axially in prosition by a bead 36 formed on handle 12.
  • valve 29 urges valve 29 to close upon seat 28.
  • wire 30 is pulled upwardly along handle 12 the valve 29 is opened to permit detergent to ilow into duct 16.
  • the socket 25 is supported on bottom 24 by a pair of spaced lugs 3'7 (only one of which is shown) the socket wall between the lugs being cut away to place the interior of the socket in communication with the tank .immediately above bottom 24.
  • the detergent flows from the tank 10 into duct 16 as shown by the Iarrows in FIG. 2.
  • duct 16 has a T branch 3S. This receives the detergent from tank 10.
  • the duct 15 has two spaced rows of holes v39 .whichfextend lengthwise of the duct. Each row of holes lies on opposite sides of rib 63, the arrangement being that a stream of detergent is directed down each side of plate 15 towards the flared edges 23 which discharge the detergent as liquid into the upper parts or root region of the bristles.
  • the wire 30 is connected to a linger piece'or trigger 40 (FIG. 6) which is immediately beneath a handle grip 41.
  • trigger 40 When trigger 40 is pulled upwardly against the action of spring 34 the valve 29 is opened and detergent is discharged into duct 16 and thence on to plate 15 and into the bristles of brushes 14.
  • the cover plate is so constructed and arranged as to direct the detergent away from roller 13 (so that the detergent can not come into contact therewith) and into the brushes 1.4. Consequently the roller 13 serves no function in agitating the detergent received from the tank thereby totproduce foam which is to be distributed on to the carpet. Instead the liquid detergent is delivered to the brushes and is agitated by the bristles to produce foam and the foam is spread on to and-replaceable e.g.;for cleaningl andrmaintenance.
