This invention is described and defined with reference to the dispensing apparatus in its normal use position, wet cleaning an upper horizontally orientated surface, hence terms such as "upper", "lower", and l'depending" should be construed in the light of this orientation. However, it is to be appreciated that other orientations are equally possible and that corresponding changes in terms such as those above may be necessary in the light of those other orientations to fully understand this invention.
The housing of the wet cleaning device preferably includes a head portion which is disc-shaped, with the skirt portion depending continuously from the peripheral edge thereof.
The housing preferably also includes a handle portion to hold and manipulate the apparatus during use. That handle portion is preferably elongated, having opposed connection ends, one of which is pre~erably connected to the h~ad and skirt portions, through a neck portion o~ the housin~.
3~ Preferably, the handle portion is movably connected to ' .
-3a-f'~ '' ,, ~ ~ v v the neck pDrtion. That connection is preferably adjustable and may be arranged so as to pennit universal movem~nt between the nec~ and handle portions, althoucJh it has h~en found sufficient to provide pivotal movement in a single plane. That plane may lie parallel to the longitudinal extent of the handle portion and perpendicular to the general plane of the head portion.
The adjustable connection is preferably provided by a connection device which includes a connection element on each of the neck and handle portions arranged to slide relative to each other, and a fastening member pivotably interconnecting the elements. The pivot member is preferably operable to loosen and tighten the interconnection between the pair of connection elements and thereby control relative movement between the neck and handle portions.
Preferably, the dispensing reservoir is located in and defined by the neck portion. Further, the housing preferably completely encloses the mainstream passage~ay. In that regard the mainstream passageway preferably extends through the dispensing reservoir in the neck portion.- Preferably the passageway also extends within the handle portion of the housing so that the inlet end thereof is positioned at the connection end OI the handle portion remote from the neck portion. In this way, a source of pressurized water mainstream is prefera~ly connectable to the inlet end of the mainstream passageway, coaxially wi~h the handle portion of the apparatus.
A suitable sealing element is preferably interposed between the lug element5 to seal the mainstream passa~eway extending therethrough. The mainstream passageway preferably also protrudes through the neck portion into the brush chamber to the outlet end. That outlet end is preferably constricted tO
form water mainstream passing therethrough into a jet stream.
The control means of the dispensing apparatus is preferably a control device which includes tap valve movably mounted in a control passageway in the housing~ The tap valve is preferably located over the outlet passageway, and is movable exteriorly of the housing to extend lnto that outlet passageway to control communication of liquid between 3:~ the reservoir and mainstream passageway to be entrained in the ~ -4-~: !

passing water mainstream.
Preferably the tap valve is removable from the control passageway to permit filling of the dispensing reservoir.
The impeller members are preferably shaped to facili-tate liquid impingement and subsequent removal from the path of the members. As will be appreciated by those skilled in the art those members preferably have a suitable concaved impinge-ment face.
The skirt portion preferably contains the water main-stream and entrained liquid within the region of the brushbristles for wet cleaning once the mainstream and liquid has been used to drive the impeller members. In that regard the skirt portion preferably deflects water mainstream and entrained liquid issuing substantially tangentially from the impeller members toward the brush bristles and surface being cleaned.
The skirt portion preferably diverges radially from the head portion to facilitate orderly deflection.
In addi-tion the housing preferably includes a ~eflector portion mounted on the peripheral edge of the s~irt portion and extending radially inwardly thereof along an extent at least adjacent the outlet end of the mainstream passageway.
This deflector portion preferably deflects water mainstream and entrained liquid, issuing substantially axially between the lmpeller members from the outlet end of the mainstream pas-sageway, radially inwardly toward the brush bristles.
Preferably, the wet cleaning device further includes a ring of brush bristles mounted in and depending from the peri-pheral edge of the skirt portion. Those bristles preferably extend continuously about that peripheral edge and diverge slightly therefrom.

FIG. a is a cross-section view throuyh IV-IV o~ FIG. l; and FIG. 5 is a cross-sec~ion~l ~)lan ~ of a portion of FIG. 1 The drawings illustrate a pre~erred dispensing apparatus, generally designated 1. Appara-tus 1 includes housing 2, having head portion 3, of generally disc-like shape, and skirt portion 4 depending from a peripheral edge of head portion 3 to terminate in peripheral edge 5. Deflec-tor portion 6, is mounted on peripheral edge 5, and projects radially inwardly thereof along at least a short peripheral extent. Skirt portion 4, diverges radially from head portion 3 and with head portion 3 and deflector portion 6, defines chamber 7. As.will become more apparent hereinafter, deflector portion 6 and recess 7, facilitate control of water mainstream during use of apparatus 1.
Head portion 3, and skirt portion 4, merge at the peripheral edge of head portion 3, into neck portion 8.
In that regard the mergence is such that housing 2 generally tapers diametrically across head portion 3, from neck portion 8, so that a relatively streamlined shaped housing 2, results.
' This shape facilitates wet cleaning hetween closely spaced apart surfaces.
Housing 2, also includes elongated handle portion 9 for manipulation of apparatus 1. Handle por-tion 9, has opposed connection ends 10,11, end 10, being connected to neck portion 8, through adjustable connection device 12. Connection device 12, permits movement o handle portion 9,,relative to the remainder of housing 2, thereby allowing an adequate clearance between the surEace being cleared and handle portion 9, to allow clear yripping of handle portion 9, and .
avoidance of accidental contact between handle portion 9, and the surface.
Connection device 12, includes connection elements in the form of lugs 13,14, each provided on a respective one of neck portion 8, and handle portion 9. Those luys 13~14, are aligned along apertures extending therethrough and have opposed sliding surfaces 15,16, respectively which rota~ably slide relative to one another during ad~ustment of handle portion 9.
,~ 1ugs 13,14 and thus neck portion 8, and h~ndle portion 39 9, are secured together with fastening member 17. In that . AJ -7-.

regard fastening member 17 includes ~asteniny head 18 and pivot shaft 19, extencling there~rorn throuyh -the apertures in aligned lugs 13,14 to be screw threadedly mounted in-to lug 13. The arrangement is such that faste~ing head 18 co-acts with lug 14, and pivot shaft 19,-co-acts with luy 13, to axially locate surfaces 15,16 relative to each, manual gripping and turning o~ fastening head 18, rotating pivot shaft 19, in screw-~hreaded mounting to axially move lugs 13,14 toward and away from each other, dependin~ on direction of turning, thereby adjusting contact pressure between surEaces 15,16 to prevent or permit respectively, relative sliding therebetween.
A mainstream passageway 20 is provided in housing 2, and extends from inlet end 21, at connection end 11, of handle portion 9 along handle portion 9, through connection 12, and along neck portion 8 to outlet end 22, projecting into chamber 7, of housing 2. Inlet end 21, is suitably adapted for releasable connection to a pressurized cleaning water mainstream sourc~, such as a water hose or pipe. :Lugs 13,1 are provided with aligned openings 23,24 in thier sliding surfaces 15,16 respectively to allow free communication of water mainstream aIong passageway 20, between handle portion 9r and neck portion 8~ and an annular gasket seal 25 is mounted between surfaces 15,16 to seal openings 23,Z4 against water mainstream leakage fro~ between surfaces 15,16~
Outlet end 22, o~ mainstream passageway 20, is adapted to form water mainstream issui.ng there~rom into a jetst~eam projecting into chamber 7, above deElector portion 6. To that end outlet end 2Z, is formed into jetstream nozzle 26, contiguous with outlet end 22. The construction and arrange- I
ment o~ nozzle 26, will be more fully described hereinafter.
A dispensing reservoir 27, from which liquid, such as a soap or detergent solution, is entrained in the wa,er mainstream passir.5 through passaseway 20, is provided in, and defined by, neck portion 8, oE housing 2. Reservoir 27, surrounds mainstream passageway 20, and communicates therewith throug~ inlet passageway 28, and outlet passageway 29, to allow com~.unication of water mains~ream from mains-tream 3~ passageway 2n, through inlet passageway 28, into reservoir .

To encouraye that communication mainstream passageway 20, tape~s from each of the inlet passageway 28 and outlet passageway 2q, causing constriction and thus drop in water mainstream pressure there-between. A small degree of taper has been found sufficient since a small pressure drop in water mainstream assists flow of that mainstream into reservoir 27.
Control d~ice 30, is provided to regulate water main-stream co~munication with reservoir 27, and thus degree of mixing of liquid therein with that mainstream. .Control device 30, includes control passageway 31, in housing 2 communicating reservoir ~7, with the e~terior of housing 2, and a tap valve 32, movably mounted in control passageway 31.
Tap valve 32 includes control knob 33, loca.ted exteriorly of housing 2, with control shaft 34, connected thereto and arranged to extend into control passageway 31. Control shaft 34, is removably screwthreaded into control passageway- 36, so that rotation of control knob 33, causes tap valve 32, to move axially into and out of control passageway 31, depending on the direction of rotation oE control knob 33.
Tap valve 32 al50 includes a needle closure member 35, connected to control shaE~ 34, and arranged to extend in~o dispensing reservoir 27 and co-operate w.i-th outlet passageway 29, to control communication between mainstream passageway . 20 and dispensing reservoir 27, through outlet passageway 2~, on rotation of control knob 33. In that regard closure member . 35, is arranged to seat in, and be spaced from, outlet passageway 29 to block and unblock that co~munication respect~
ively. To facilitate seating closure member 35, and outlet passageway 29, are compatibly shaped, such as by tapering closure member 35, and countersinking outlet passayeway 29.
An annular seal 36, is mounted on control shaft 34, to s~al shaft 34, to control passageway 31, to resist leakage of liquid from reservoir 27 through control passageway 31.
Tap valve 32 is removable from control passageway 31, to allow access to dispensing reservoir 27, for filliny with ~. J

Brush m~ans 37, is mounted on housing 2, and includes brush member 38, rotatably mounted on head portion 3, thereof.
Brush member 38, includes disc shaped brush support 3~, positioned in recess 7, and having opposed faces 40,41 interconnected by peripheral edge 42, and central aperture 43, extending between faces 40,41. Axle 44 is connected to head portion 3, and protrudes into chamber 7, for rotatable mounting of brush support 39 thereto~ Boss 45, formed on face 40 of brush support 39, maintains face 40, spaced from head portion 3, and nozzle 26, for clear rotation, and fastening clip 46 located on axle 44, securely maintains brush supp~rt .
39, mounted on axle 44.
Brush member 38, also includes a plurality of impeller members 47, in the form of reac-tion-type impeller blades mounted spacecl apart about peripheral edge 42, of brush support 39. Noz~le 26, is arranged immediately above and facing the concave surface o~ blades 47, and deflector portion 6, the arrangement being such that water mainstream and entrained liquid passing through nozzle 26, in a jet stream impinges on successive blades 47, causing ~rush member 38 to rotate.
Brush mem~er 38, furt~er include5 a set o~ brush br.istles 48, mounted in and depending from face 41, of brush support 39, for rotation therewi~h.
Brush means 37, also include5 a ring of brush bristles 4g, mounted in the peripheral edge 5, of skirt portion 4, and depending therefrom ~eyond the set of brush bristles 48, o~
brush member 38. Those brush bristles 49, extend continuously about skirt portion 4, and diverge outwardly therefrom.
Dispensing apparatus 1, may be manufactured in any suitable manner and from any suitable materi~ls. In this preferred embodiment it has been found suitable to mould various components of apparatus 1, and then fabricate those components into apparatus 1. In that regard head portion 3, 39 skirt portion 4, neck portion 8, and connection lug 13, may bo 1 ~ 5 526 0 moulded in one pi.ece. Apparatus 1, may be composed prln~ip-ally o:E plastics material.
In use o~ dispensing apparatus 1, dispensing liquid such as a liquid soap or detergen-t solu-tion, is initially placed in the dispensing reservoir 27, through control passageway 31, until reservoir 27 is ~ull. Tap valve 32, is then firmly placed in control passageway 31.
A source o~ pressurized cleaning water mainstream is connected to inlet end 21, of mair.stream passageway 20, such as by way of a hose or pipe. The water mainstream passes through mainstream passageway 20, exiting through jet nozzle 26 to impinge on impeller blades 47 causing brush member 38, to rotate. Following impingement the water mainstream falls under the action of gravity and its residual pressure to co-act with brush bristles 48, and 49, to wet clean a surface upon which those hristles 48, and 49, are placed.
In view of ~he pressure drop in mainstream passageway 20, between inle~ passageway 28, and outlet passageway 29, a small portion oE water mainstream is diverted from mainstream passageway 20 through inlet passageway 28, to reservoir 27, .and a similar small proportion of the dispensing liquid passes through out~et passageway 29, ko mainstream passayeway 20, to be entrained in passing water ma.instream and be dispensed with it through jet nozzle 2G. The qu~ntity oE
dispensiny liquid and the proportion of it entrained in the water mainstream is controlled by rotation oE control knob 33, to adjust tap val.ve 32, relative to.outle~ passageway 29. If tap valve 32, is moved to block outlet passageway 29, no dispensing li~uid will be entrained in the water mainstream whilst on unblocking outle-t passageway 29S the proportion of dispensing li~uid entrainea may be varied with-out interrupting the passage of water mainstream along mainstream passaseway 20.
It will be appreciated that the dispensing liquid within reservoir 27, will progressively be diluted with water main~
stream so that at intervals it will ~e necessary to remove tap valve 32, empty reservoi.r 27, and recharge it with dispensing 3 liquid.
.
~- ~ 155260 The apparatus of the presert invention in-tegrally incorporates brush means therein for wet cleaning. As such the overall size of the apparatus when compared -to similar prior arrangements can be reduced thereby facilitating-handling during use. Moreover because of tha-t integration, inadvertent loss of a component of that dispensing apparatus may be minimized. Costs of manufacture rnay also be minimized.
Finally, it is to be understood that various other modifications and/or alterations may be made without d~parting from the scope of the present invention as herein defined by the appended claims.

FIG. a is a cross-section view throuyh IV-IV o~ FIG. l; and FIG. 5 is a cross-sec~ion~l ~)lan ~ of a portion of FIG. 1 The drawings illustrate a pre~erred dispensing apparatus, generally designated 1. Appara-tus 1 includes housing 2, having head portion 3, of generally disc-like shape, and skirt portion 4 depending from a peripheral edge of head portion 3 to terminate in peripheral edge 5. Deflec-tor portion 6, is mounted on peripheral edge 5, and projects radially inwardly thereof along at least a short peripheral extent. Skirt portion 4, diverges radially from head portion 3 and with head portion 3 and deflector portion 6, defines chamber 7. As.will become more apparent hereinafter, deflector portion 6 and recess 7, facilitate control of water mainstream during use of apparatus 1.
Head portion 3, and skirt portion 4, merge at the peripheral edge of head portion 3, into neck portion 8.
In that regard the mergence is such that housing 2 generally tapers diametrically across head portion 3, from neck portion 8, so that a relatively streamlined shaped housing 2, results.
' This shape facilitates wet cleaning hetween closely spaced apart surfaces.
Housing 2, also includes elongated handle portion 9 for manipulation of apparatus 1. Handle por-tion 9, has opposed connection ends 10,11, end 10, being connected to neck portion 8, through adjustable connection device 12. Connection device 12, permits movement o handle portion 9,,relative to the remainder of housing 2, thereby allowing an adequate clearance between the surEace being cleared and handle portion 9, to allow clear yripping of handle portion 9, and .
avoidance of accidental contact between handle portion 9, and the surface.
Connection device 12, includes connection elements in the form of lugs 13,14, each provided on a respective one of neck portion 8, and handle portion 9. Those luys 13~14, are aligned along apertures extending therethrough and have opposed sliding surfaces 15,16, respectively which rota~ably slide relative to one another during ad~ustment of handle portion 9.
,~ 1ugs 13,14 and thus neck portion 8, and h~ndle portion 39 9, are secured together with fastening member 17. In that . AJ -7-.
, . : . , ,, ' . ', S5~
regard fastening member 17 includes ~asteniny head 18 and pivot shaft 19, extencling there~rorn throuyh -the apertures in aligned lugs 13,14 to be screw threadedly mounted in-to lug 13. The arrangement is such that faste~ing head 18 co-acts with lug 14, and pivot shaft 19,-co-acts with luy 13, to axially locate surfaces 15,16 relative to each, manual gripping and turning o~ fastening head 18, rotating pivot shaft 19, in screw-~hreaded mounting to axially move lugs 13,14 toward and away from each other, dependin~ on direction of turning, thereby adjusting contact pressure between surEaces 15,16 to prevent or permit respectively, relative sliding therebetween.
A mainstream passageway 20 is provided in housing 2, and extends from inlet end 21, at connection end 11, of handle portion 9 along handle portion 9, through connection 12, and along neck portion 8 to outlet end 22, projecting into chamber 7, of housing 2. Inlet end 21, is suitably adapted for releasable connection to a pressurized cleaning water mainstream sourc~, such as a water hose or pipe. :Lugs 13,1 are provided with aligned openings 23,24 in thier sliding surfaces 15,16 respectively to allow free communication of water mainstream aIong passageway 20, between handle portion 9r and neck portion 8~ and an annular gasket seal 25 is mounted between surfaces 15,16 to seal openings 23,Z4 against water mainstream leakage fro~ between surfaces 15,16~
Outlet end 22, o~ mainstream passageway 20, is adapted to form water mainstream issui.ng there~rom into a jetst~eam projecting into chamber 7, above deElector portion 6. To that end outlet end 2Z, is formed into jetstream nozzle 26, contiguous with outlet end 22. The construction and arrange- I
ment o~ nozzle 26, will be more fully described hereinafter.
A dispensing reservoir 27, from which liquid, such as a soap or detergent solution, is entrained in the wa,er mainstream passir.5 through passaseway 20, is provided in, and defined by, neck portion 8, oE housing 2. Reservoir 27, surrounds mainstream passageway 20, and communicates therewith throug~ inlet passageway 28, and outlet passageway 29, to allow com~.unication of water mains~ream from mains-tream 3~ passageway 2n, through inlet passageway 28, into reservoir .

~ ., i ~ ~15,~60 27 and communic~tion of dispensing liq~licl through ou~let passageway 29 to mainstream passageway 20 for entrainment into passing water mainstream. To encouraye that communication mainstream passageway 20, tape~s from each of the inlet passageway 28 and outlet passageway 2q, causing constriction and thus drop in water mainstream pressure there-between. A small degree of taper has been found sufficient since a small pressure drop in water mainstream assists flow of that mainstream into reservoir 27.
Control d~ice 30, is provided to regulate water main-stream co~munication with reservoir 27, and thus degree of mixing of liquid therein with that mainstream. .Control device 30, includes control passageway 31, in housing 2 communicating reservoir ~7, with the e~terior of housing 2, and a tap valve 32, movably mounted in control passageway 31.
Tap valve 32 includes control knob 33, loca.ted exteriorly of housing 2, with control shaft 34, connected thereto and arranged to extend into control passageway 31. Control shaft 34, is removably screwthreaded into control passageway- 36, so that rotation of control knob 33, causes tap valve 32, to move axially into and out of control passageway 31, depending on the direction of rotation oE control knob 33.
Tap valve 32 al50 includes a needle closure member 35, connected to control shaE~ 34, and arranged to extend in~o dispensing reservoir 27 and co-operate w.i-th outlet passageway 29, to control communication between mainstream passageway . 20 and dispensing reservoir 27, through outlet passageway 2~, on rotation of control knob 33. In that regard closure member . 35, is arranged to seat in, and be spaced from, outlet passageway 29 to block and unblock that co~munication respect~
ively. To facilitate seating closure member 35, and outlet passageway 29, are compatibly shaped, such as by tapering closure member 35, and countersinking outlet passayeway 29.
An annular seal 36, is mounted on control shaft 34, to s~al shaft 34, to control passageway 31, to resist leakage of liquid from reservoir 27 through control passageway 31.
Tap valve 32 is removable from control passageway 31, to allow access to dispensing reservoir 27, for filliny with ~. J
39~ liquid. In that regard, housing 2, may be recessed about AJ _g_ _ ... .. , . . , : .

115,~&0 control pa~s~geway 31, to form a liquid drain ~not shown) into control passageway 31. In this ~tay li~uid spilt abou-t control passageway 31 during filling of reservoir 27, drains in-to passageway 31, and thereafter reservoir 23 to minimize liquid loss.
Brush m~ans 37, is mounted on housing 2, and includes brush member 38, rotatably mounted on head portion 3, thereof.
Brush member 38, includes disc shaped brush support 3~, positioned in recess 7, and having opposed faces 40,41 interconnected by peripheral edge 42, and central aperture 43, extending between faces 40,41. Axle 44 is connected to head portion 3, and protrudes into chamber 7, for rotatable mounting of brush support 39 thereto~ Boss 45, formed on face 40 of brush support 39, maintains face 40, spaced from head portion 3, and nozzle 26, for clear rotation, and fastening clip 46 located on axle 44, securely maintains brush supp~rt .
39, mounted on axle 44.
Brush member 38, also includes a plurality of impeller members 47, in the form of reac-tion-type impeller blades mounted spacecl apart about peripheral edge 42, of brush support 39. Noz~le 26, is arranged immediately above and facing the concave surface o~ blades 47, and deflector portion 6, the arrangement being such that water mainstream and entrained liquid passing through nozzle 26, in a jet stream impinges on successive blades 47, causing ~rush member 38 to rotate.
Brush mem~er 38, furt~er include5 a set o~ brush br.istles 48, mounted in and depending from face 41, of brush support 39, for rotation therewi~h.
Brush means 37, also include5 a ring of brush bristles 4g, mounted in the peripheral edge 5, of skirt portion 4, and depending therefrom ~eyond the set of brush bristles 48, o~
brush member 38. Those brush bristles 49, extend continuously about skirt portion 4, and diverge outwardly therefrom.
Dispensing apparatus 1, may be manufactured in any suitable manner and from any suitable materi~ls. In this preferred embodiment it has been found suitable to mould various components of apparatus 1, and then fabricate those components into apparatus 1. In that regard head portion 3, 39 skirt portion 4, neck portion 8, and connection lug 13, may bo 1 ~ 5 526 0 moulded in one pi.ece. Apparatus 1, may be composed prln~ip-ally o:E plastics material.
In use o~ dispensing apparatus 1, dispensing liquid such as a liquid soap or detergen-t solu-tion, is initially placed in the dispensing reservoir 27, through control passageway 31, until reservoir 27 is ~ull. Tap valve 32, is then firmly placed in control passageway 31.
A source o~ pressurized cleaning water mainstream is connected to inlet end 21, of mair.stream passageway 20, such as by way of a hose or pipe. The water mainstream passes through mainstream passageway 20, exiting through jet nozzle 26 to impinge on impeller blades 47 causing brush member 38, to rotate. Following impingement the water mainstream falls under the action of gravity and its residual pressure to co-act with brush bristles 48, and 49, to wet clean a surface upon which those hristles 48, and 49, are placed.
In view of ~he pressure drop in mainstream passageway 20, between inle~ passageway 28, and outlet passageway 29, a small portion oE water mainstream is diverted from mainstream passageway 20 through inlet passageway 28, to reservoir 27, .and a similar small proportion of the dispensing liquid passes through out~et passageway 29, ko mainstream passayeway 20, to be entrained in passing water ma.instream and be dispensed with it through jet nozzle 2G. The qu~ntity oE
dispensiny liquid and the proportion of it entrained in the water mainstream is controlled by rotation oE control knob 33, to adjust tap val.ve 32, relative to.outle~ passageway 29. If tap valve 32, is moved to block outlet passageway 29, no dispensing li~uid will be entrained in the water mainstream whilst on unblocking outle-t passageway 29S the proportion of dispensing li~uid entrainea may be varied with-out interrupting the passage of water mainstream along mainstream passaseway 20.
It will be appreciated that the dispensing liquid within reservoir 27, will progressively be diluted with water main~
stream so that at intervals it will ~e necessary to remove tap valve 32, empty reservoi.r 27, and recharge it with dispensing 3 liquid.
.
~- ~ 155260 The apparatus of the presert invention in-tegrally incorporates brush means therein for wet cleaning. As such the overall size of the apparatus when compared -to similar prior arrangements can be reduced thereby facilitating-handling during use. Moreover because of tha-t integration, inadvertent loss of a component of that dispensing apparatus may be minimized. Costs of manufacture rnay also be minimized.
Finally, it is to be understood that various other modifications and/or alterations may be made without d~parting from the scope of the present invention as herein defined by the appended claims.
