FIG. 4 is a sectional view somewhat similar to FIG. 3 but showing the valve in position to effect the supply of soapy water to the spray shower nozzle; and

FIG. 5 is a top plan view of the valve shown in FIGS. 2, 3 and 4.

DESCRIPTION OF PREFERRED EMBODIMENT OF INVENTION In FIG. 1 of the drawings, I have shown an inlet pipe for a shower, for supplying water to the shower under the control of a valve 11 on a spout 12 for a conventional bathtub (not shown). The usual hot and cold water valves generally indicated by reference numeral 13 control the supply of hot, cold or mixed water through the spout l2 and through thesupply pipe 10, when the valve 11 is in position to block the supply of water through said spout. Thepipe 10 is connected with anelbow 15 having apipe 16 leading therefrom into the shower bath and having a conventional form ofuniversal coupling 17 on the end thereof. Apipe 18 leads from said universal coupling, and is connected with a soap mixing and dispensingshower head 19 constructed in accordance with the principles of the present invention. Theshower head 19 andpipe 18 may be moved relative to thepipe 18 about the universal coupling, to control the direction of spray from the shower head in a conventional manner.

The soap mixing anddispensing shower head 19 includes avalve block 20 having aninlet 21 leading thereinto and adapted to be threaded on the end of thepipe 18. Thevalve block 20 has an axially alignedoutlet 22 leading therefrom having a spray-shower nozzle orhead 23 threaded therein. The spray-shower nozzle orhead 23 may be a conventional form of spray nozzle and is herein shown as being formed from a plastic material threaded into theoutlet 22, although it need not necessarily be made from plastic.

Thevalve block 20 is shown as being generally rectangular in cross section and has a flattop face 25 forming a mounting for acontainer 26. As shown in the drawings, thecontainer 26 is generally cylindrical in form and may be made from a transparent plastic material to contain a cake of soap (FIG. I) to be sprayed with water by aspray nozzle 27. A detachable cover, 28 serves to close said soap container.'Thespray nozzle 27 is spaced to one side of said container and extends above abottom plate 29 of said soap container. Thebottom plate 29 is shown as abutting the flattop face 25 of thevalve block 20 and may be adhesively secured thereto.

As shown in FIGS. 3, 4 and 5, thenozzle 27 is in the form of an inverted generally cup-shaped member having a cylindrical interior wall and having a portion of the outer wall formed to conform to the interior cylindrical wall of thecontainer 21. Aspray slit 31 leads through the cylindrical wall of said spray nozzle and is spaced above the bottom of thebottom plate 29, in position to spray water on a cake of soap contained within said container.

Thenozzle 27 is supplied with water through apassageway 32 leading through thebottom wall 29 thereof and having communication with achannel 33 in the top surface of thevalve block 20 and leading inwardly of thepassageway 32 in a direction extending radially of the soap container. A drilled hole orpassageway 34 leads inwardly along the valve block from thechannel 32 to a generallycylindrical valve chamber 35, extending along thevalve block 20 at right angles to theinlet 21 andoutlet 22 and opening to opposite ends of said valve block. Aslide valve 36 is slidably mounted in said valve chamber, and projects beyond opposite ends thereof, to be engaged at either end of a finger of the hand to move thevalve 36 into its selected operative positions.

A soap channel 37 for soapy water, leads through thebottom wall 29 of thecontainer 26 and is disposed on the opposite side of said container from thespray nozzle 27. The soap channel 37 has communication with an upwardlyopening channel 39 extending along the top face of thevalve block 20 and closed by thebottom wall 29 of thecontainer 26. Apassageway 40 leads from thechannel 39 inwardly along the valve block and opens to thevalve chamber 35 and, is shown in FIG. 2 as being in alignment with theclear water channel 33.

Thevalve 36 is shown as being a generally cylindrical slide valve having first andsecond passageways 41 and 43 recesses therein and shown in transverse section as being in the fonn of sectors of a circle and opening to the wall of thevalve chamber 35. Thefirst passageway 41 has communication with theinlet 21 and thepassageway 35 to supply water to thechannel 33 and spray 27. Thesecond passageway 43 has communication with theoutlet 22 and the soap channel 37 through thechannel 39 andpassageway 40 to accommodate the fiow of soapy water through theoutlet 22 andspray nozzle 23. Apassageway 44 of a relatively small cross-sectional area affords communication with theinlet 21 and connects thefirst passageway 41 to thesecond passageway 43, to create a Venturi effect by the pressure drop of water flowing through the valve, to thereby aspirate soapy water from the soap channel 37,channel 39 andpassageway 40 into thespray nozzle 23, to

be discharged from said spray nozzle onto the body of the bather. When thevalve 36 is in the position shown in FIG. 2, clear water will be supplied to thespray nozzle 27 to be sprayed over a bar of soap in thecontainer 26, through theslit 31. At the same time water under pressure, flowing through thepassageway 44 and opening to thepassageway 43 will positively draw soapy water from the soap channel 37 to be discharged in the form of a spray through thespray shower nozzle 23.

Thevalve 36 is also shown as having aclear water passageway 45 leading diametrically therethrough in direct alignment with theinlet 21 andoutlet 22, as thevalve 36 is moved into position to close thepassageways 34 and 40, and to efiect the discharge of clear water through thespray nozzle 23. O-rings 46, 46 are shown as recessed in the valve body on opposite sides of thepassageways 41, 43 and 45 to retain the water to a selected of said passageways and to prevent the leakage of water from thevalve block 20. The O-rings 46, 46 are of a conventional form so need not herein be shown or described in detail.

A slot 47 is recessed in thevalve 36 and extends axially therealong between the O-rings 46, 46 and is engaged by astop pin 48 extending inwardly along the valve block from the bottom thereof, into thevalve chamber 35 and slot 47. The slot 47 forms a stop slot and opposite ends thereof terminate in such relation relative to the first andsecond passageways 41 and 43 and theclear water passageway 45 that as thevalve 36 is moved in one direction to engage an end of theslot 47 with thepin 48, thepassageway 45 will be in axial alignment with theinlet 21 andoutlet 22, to discharge clear water through thespray nozzle 23. As thevalve 36 is moved in an opposite direction to the opposite extreme end of the slot 47, thefirst passageway 41 will be in registry with theinlet 21, to supply clear water to thespray 27 while thesecond passageway 43 will he in registry with theoutlet 22, to effect the aspiration of soapy water from the soap channel 37 to be discharged through thespray nozzle 23.

Thestop pin 48 has an enlargedhead 49 on its outer end, forming a knob enabling thestop pin 48 to be moved out of registry with the stop slot 47 when it is desired to remove thevalve 36 from thevalve block 20.

In the drawings, thevalve block 20,valve 36,soap container 26 andspray nozzle 23 are shown as made from a plastic material which preferably may be a suitable form of transparent plastic such as a transparent nylon plastic material. It should be understood, however, that the device need not be made from a transparent plastic but may be made from any other suitable plastic material, and may be made from metal, if desired.
