  • a tap may be positioned along the length of the pipe.
  • each said jet overlaps with its neighbouring jet or jets to present a continuous liquid front along substantially the entire length of the roller.
  • the support means may be separable from the housing and may include spindles capable of protruding into the open ends of a roller shaft, these support means being shaped and dimensioned to preclude rotation relative to the housing during use and the spindles being dimensioned to allow for rotation of the roller relative to the housing.
  • the manifold may be circular in cross section; the manifold ends may be retained within collars extending inwardly into the housing from end caps of the housing.
  • the present invention provides paint roller cleaning apparatus comprising a housing, means for supporting a roller to be cleaned within the housing whilst enabling the roller to spin freely about its longitudinal axis, means for conveying water to a manifold positioned within the housing through a port positioned generally midway between the manifold ends, the manifold including a plurality of orifices through which water is discharged as discrete jets onto the surface of the roller, the orifices to one side of the point at which water is admitted to the manifold being positioned at substantially the same distances from this point of admission as the orifices to the other side of the point of admission, and the orifices being so aligned that jets of water issuing therefrom make contact with the roller surface at positions offset from the longitudinal axis of the roller.

  • Figures 4 and 5 are plan and side views of roller supports for use with the apparatus of Figure 1.
  • the roller cleaning apparatus illustrated in the drawings comprises a generally cylindrical hollow housing 1 provided with a cover 2 which is removable to enable a paint roller 3 (shown in broken line in Figure 1) to be positioned within the housing interior between removable supports 4,5 (see Figures 4 and 5).
  • the base of the housing is closed by an end-cap 6.
  • the cover, end cap, housing and supports may be produced from a plastics material.
  • the roller is of conventional configuration and comprises an outer paint absorbing tubular layer carried by an inner hollow shaft 7.
  • a manifold 8 Positioned within the interior of the housing 1 is a manifold 8 formed with a series of discrete orifices 9. These orifices are preferably rectangular or fan shaped in section.
  • a pipe 10 communicates with the manifold 8 through an inlet port 11.
  • a tap 12 is positioned within the pipe 10. The end of pipe 10 is ribbed to receive one end of a hose connected to a source of mains water.
  • the port 11 is positioned substantially halfway along the length of the manifold 8 with the orifices 9 above the port 11 being substantially the same distances from the port as the respective orifices below the port 11.
  • a conical flow diverter 14 which operates to direct water equally towards the upper and lower ends of the manifold.
  • each orifices 9 The positioning of the orifices 9 with respect to the inlet port 11 and the diverter 14 ensure that the volume and pressure of water supplied to, and therefore leaving, each orifice is substantially the same. Thus, each orifice contributes substantially equally to the cleaning operation.
  • the manifold ends are located within collars 15 projecting inwardly into the housing from the cover 2 and end cap 6.
  • the lower end if the manifold 8 extends to a position below the lowermost orifice 9 to avoid the formation of vortices created by the water present in the manifold.
  • One or more drain holes are formed in the end-cap 16 for the outflow of polluted water.
  • Each support has a plurality of radially extending arms 17 and an upwardly or downwardly protruding spindle 18.
  • the supports are generally round but with one side 19 describing a straight line.
  • the spindles 18 locate within the open ends of the shaft 7 of the roller 3 and the assembly of the supports 4,5 and the roller 3 is lowered into the housing. The roller 3 rotates about the spindles 18 when the roller is acted upon by the water jets.
  • the longitudinal axis of the roller 3 mounted between the supports 4,5 is offset from the centre line of the housing.
  • the longitudinal axis of the roller is also generally parallel to the longitudinal axis of the manifold 8.
  • the discharge orifices 9 of the manifold 8 are therefore directed towards points on the roller surface which are offset from the longitudinal axis of the roller.
  • a roller to be cleaned is positioned within the housing with the lower ⁇ most support 5 seated within the end-cap 6 and the roller 3 held on and between the spindles 18 of the supports 4,5.
  • the pressure applied by the spindles is insufficient to inhibit free rotation of the roller.
  • a hose connected to a mains water supply is then connected to the pipe 10.
  • Water entering the manifold is directed substantially equally to the respective manifold ends by the conical diverter and the positioning of the orifice pairs substantially equidistant from the port 11 ensures that the pressure and volume of water leaving each orifice is substantially the same. Because of their alignment, the jets emitted make contact with the roller surface at positions offset from the rollers longitudinal axis thereby imparting rotational movement to the roller. This rotational movement assists speedy and efficient cleaning of the roller.
  • a paint roller can be cleaned thoroughly within 6 to 10 minutes.
  • the manifold 8 has six discharge orifices 9 in each of which is positioned a nozzle. There may, however, be a greater or lesser number of orifices if desired.
  • Each nozzle has a generally hemispherical front face in which is set a slotted discharge orifice.
  • the construction of the nozzles is such that a fan-shaped jet of water or other cleaning fluid is produced, and the distance between the nozzles is set such that the fan-shaped jets overlap before coming into contact with the roller. Thanks to the positioning of the inlet port 11 and the orifices 9, the pressure of liquid emerging from the nozzles is substantially constant along the line of nozzles. Consequently, the liquid pressure is substantially even along the entire liquid front.
