Description
SUMMARY AND OBJECTS OF THE INVENTION
In carrying out my invention I connect a valve block to a water
inlet pipe extending into the shower for universal movement with
respect to the inlet pipe and connect a spray-shower nozzle or head
to the valve block to extend from the valve block. I mount a
container for bar soap on top of the valve block and provide a
spray in the soap container for spraying water over the bar soap
and draw soapy water from the container to be discharged through
the spray nozzle, under the control of a slide valve movable into
position to supply either clear or soapy water to the shower-spray
nozzle.
A principal object of the present invention, therefore, is to
provide a simplified form of shower head so arranged as to
selectively supply clear or soapy water to a shower nozzle.
Another object of the invention is to provide an efficient and
economical form of soap-mixing-and-dispensing shower head, which
may be detachably mounted on the supply pipe for the shower and
includes a selectively operable valve, enabling the bather to
select clear or soapy water.
A still further object of the invention is to provide an improved
form of soap-mixing-and-dispensing valve for shower heads which may
be attachable to a conventional inlet water connection for a shower
to enable the bather to select clear or soapy water by the simple
operation of moving a valve into one or another limited
position.
Still another object of the invention is to provide an attachment
to replace the conventional shower head for a shower bath and the
like, arranged to enable the bather to select either clear or soapy
water by a simple manual operation.
A still further object of the invention is to provide a soap mixer
and dispenser forming an attachment for a shower head in which
clear water may be sprayed over a cake of soap and aspirated
through the spray nozzle of the shower head, or clear water free
from soap may be selectively discharged through the shower
head.
A still further object of the invention is to provide a
soap-mixing-and-dispensing shower head selectively operable to
dispense soapy or clear water and arranged with a view toward
utmost simplicity in construction and economical use of cake
soap.
Other objects, features and advantages of the invention will be
readily apparent from the following description of preferred
embodiments thereof, taken in conjunction with the accompanying
drawings, although variations and modifications may be effected
without departing from the spirit and scope of the novel concepts
of the disclosure.

DESCRIPTION OF PREFERRED EMBODIMENT OF INVENTION
In FIG. 1 of the drawings, I have shown an inlet pipe 10 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 12 and through the supply pipe 10, when the valve 11 is
in position to block the supply of water through said spout. The
pipe 10 is connected with an elbow 15 having a pipe 16 leading
therefrom into the shower bath and having a conventional form of
universal coupling 17 on the end thereof. A pipe 18 leads from said
universal coupling, and is connected with a soap mixing and
dispensing shower head 19 constructed in accordance with the
principles of the present invention. The shower head 19 and pipe 18
may be moved relative to the pipe 18 about the universal coupling,
to control the direction of spray from the shower head in a
conventional manner.
The soap mixing and dispensing shower head 19 includes a valve
block 20 having an inlet 21 leading thereinto and adapted to be
threaded on the end of the pipe 18. The valve block 20 has an
axially aligned outlet 22 leading therefrom having a spray-shower
nozzle or head 23 threaded therein. The spray-shower nozzle or head
23 may be a conventional form of spray nozzle and is herein shown
as being formed from a plastic material threaded into the outlet
22, although it need not necessarily be made from plastic.
The valve block 20 is shown as being generally rectangular in cross
section and has a flat top face 25 forming a mounting for a
container 26. As shown in the drawings, the container 26 is
generally cylindrical in form and may be made from a transparent
plastic material to contain a cake of soap (FIG. 1) to be sprayed
with water by a spray nozzle 27. A detachable cover, 28 serves to
close said soap container. The spray nozzle 27 is spaced to one
side of said container and extends above a bottom plate 29 of said
soap container. The bottom plate 29 is shown as abutting the flat
top face 25 of the valve block 20 and may be adhesively secured
thereto.
As shown in FIGS. 3, 4 and 5, the nozzle 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 the container 21. A spray slit 31
leads through the cylindrical wall of said spray nozzle and is
spaced above the bottom of the bottom plate 29, in position to
spray water on a cake of soap contained within said container.
The nozzle 27 is supplied with water through a passageway 32
leading through the bottom wall 29 thereof and having communication
with a channel 33 in the top surface of the valve block 20 and
leading inwardly of the passageway 32 in a direction extending
radially of the soap container. A drilled hole or passageway 34
leads inwardly along the valve block from the channel 32 to a
generally cylindrical valve chamber 35, extending along the valve
block 20 at right angles to the inlet 21 and outlet 22 and opening
to opposite ends of said valve block. A slide 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 the valve 36 into its selected operative positions.
A soap channel 37 for soapy water, leads through the bottom wall 29
of the container 26 and is disposed on the opposite side of said
container from the spray nozzle 27. The soap channel 37 has
communication with an upwardly opening channel 39 extending along
the top face of the valve block 20 and closed by the bottom wall 29
of the container 26. A passageway 40 leads from the channel 39
inwardly along the valve block and opens to the valve chamber 35
and is shown in FIG. 2 as being in alignment with the clear water
channel 33.
The valve 36 is shown as being a generally cylindrical slide valve
having first and second passageways 41 and 43 recesses therein and
shown in transverse section as being in the form of sectors of a
circle and opening to the wall of the valve chamber 35. The first
passageway 41 has communication with the inlet 21 and the
passageway 35 to supply water to the channel 33 and spray 27. The
second passageway 43 has communication with the outlet 22 and the
soap channel 37 through the channel 39 and passageway 40 to
accommodate the flow of soapy water through the outlet 22 and spray
nozzle 23. A passageway 44 of a relatively small cross-sectional
area affords communication with the inlet 21 and connects the first
passageway 41 to the second 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
and passageway 40 into the spray nozzle 23, to be discharged from
said spray nozzle onto the body of the bather. When the valve 36 is
in the position shown in FIG. 2, clear water will be supplied to
the spray nozzle 27 to be sprayed over a bar of soap in the
container 26, through the slit 31. At the same time water under
pressure, flowing through the passageway 44 and opening to the
passageway 43 will positively draw soapy water from the soap
channel 37 to be discharged in the form of a spray through the
spray shower nozzle 23.
The valve 36 is also shown as having a clear water passageway 45
leading diametrically therethrough in direct alignment with the
inlet 21 and outlet 22, as the valve 36 is moved into position to
close the passageways 34 and 40, and to effect the discharge of
clear water through the spray nozzle 23. O-rings 46, 46 are shown
as recessed in the valve body on opposite sides of the passageways
41, 43 and 45 to retain the water to a selected of said passageways
and to prevent the leakage of water from the valve 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 the valve 36 and extends axially
therealong between the O-rings 46, 46 and is engaged by a stop pin
48 extending inwardly along the valve block from the bottom
thereof, into the valve chamber 35 and slot 47. The slot 47 forms a
stop slot and opposite ends thereof terminate in such relation
relative to the first and second passageways 41 and 43 and the
clear water passageway 45 that as the valve 36 is moved in one
direction to engage an end of the slot 47 with the pin 48, the
passageway 45 will be in axial alignment with the inlet 21 and
outlet 22, to discharge clear water through the spray nozzle 23. As
the valve 36 is moved in an opposite direction to the opposite
extreme end of the slot 47, the first passageway 41 will be in
registry with the inlet 21, to supply clear water to the spray 27
while the second passageway 43 will be in registry with the outlet
22, to effect the aspiration of soapy water from the soap channel
37 to be discharged through the spray nozzle 23.
The stop pin 48 has an enlarged head 49 on its outer end, forming a
knob enabling the stop pin 48 to be moved out of registry with the
stop slot 47 when it is desired to remove the valve 36 from the
valve block 20.
In the drawings, the valve block 20, valve 36, soap container 26
and spray 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.
