SHOWER BATHING DEVI CE Filed June 4, 1964 INVENTOR5' FRA B. COUR 7" MIL].

Arron/Eva United States Patent 3,207,445 SHOWER BATHING DEVICE Frank B. Court and Herbert J. Miller, Phoenix, Ariz., assignors to Dynamics Research, Inc., a corporation of Arizona Filed June 4, 1964, Ser. No. 372,582 '13 Claims. (Cl. 239-318) This invention relates to improvements in shower bathing devices. More particularly, the invention concerns novel devices for dispensing an aerated soap-water mixture for shower bathing purposes.

Devices for simultaneously dispensing soap and water for shower bathing purposes are known in the art. Generally, the prior art devices comprise either a device providing for concurrently discharging separate streams of soap and water or provide for mixing a quantity of liquid soap with the water stream and discharging a soap-water mixture therefrom. The devices of the prior art do not, however, generally provide for the production of a suds stream, rather, providing only a soap-water mixture which must be worked into a lather by the bather.

It would be advantageous to provide a device for dispensing a suds mixture comprising an aerated soapwater mixture.

Accordingly, it is an object of the present invention to provide a device for dispensing an aerated soap-water mixture as a suds.

Another object of the invention is to provide for the dispensation of such aerated mixture intermittently at the pleasure of the bather.

Another object of the invention is to provide a device for alternately dispensing an aerated water stream and, at the pleasure of the bather, an aerated soap-water stream.

Other objects of the invention will become apparent to those skilled in the art from the following detailed description of the invention and from the drawings of the embodiment of the invention chosen for illustration in which:

FIG. 1 is an exterior perspective view of the embodiment chosen for illustration showing the device attached to a water supply and a soap reservoir;

FIG. 2 is an exploded partial sectional view of the device of FIG. 1 showing the assembly relationship of the various parts of the device;

FIG. 3 is a detailed sectional view of the device of FIGS. 1 and 2 showing the assembled relationship of the component parts;

FIG. 4 is a detailed sectional view of the valve portion of the device shown in FIG. 3.

The above stated objectives are accomplished in accordance with the invention by the provision in a soap dispensing shower head device comprising a conduit attachable at its upper end to a source of water under pressure and terminating at its lower end in a head adapted to discharge a shower bathing spray and means for introducing a liquid soap into said conduit at a point intermediate the ends thereof, the improvements in combination with said device comprising an air inlet port communicating between the outside and the inside of said conduit; the first diaphragm member transversely disposed within said conduit below the air inlet port and the point where the liquid soap is introduced into said conduit, said first diaphragm member having an orifice in the central area thereof; and a second diaphragm member transversely disposed within said conduit above said air inlet port and said point of soap introduction, said second diaphragm member having an opening in the central portion thereof communicating with a nipple depending downwardly therefrom. The space between the dia- 3 ,207,445 Patented Sept. 21, 1965 phragm members defines a soap-air mixing chamber and the stream of water injected from the nipple through the orifice in the lower diaphragm member provides an aspirating effect which draws the soap and air into the mixing chamber, induces mixing therebetween and withdraws the aerated soap from the mixing chamber forming a suds for discharge as a shower bathing spray from the lower end of the device.

A better understanding of the invention will be facilitated by reference to the drawings.

FIG. 1 is an external view of the embodiment chosen for illustration shown attached at its upper end 1 to a source of water under pressure, in this instance a supply pipe 2 which is threaded at its lower end 3 to receive the internally threaded female adapter 4 on the upper portion of the device. Air enters the mixing chamber through the inlet port 5 and is mixed therein with soap aspirated from the soap receptacle 6 when the soap valve 7 is in the open position as shown. The aerated soap-water mixture or suds is discharged through the shower head 8 on the lower end of the device.

In FIG. 2 the device of FIG. 1 is shown in exploded sectional view to facilitate an understanding of the assembly of the components of the device. The components comprise a body portion 11 which comprises a barrel portion 12 flared at its lower end 13 which is provided with internal discharge slots 14, an integral valve body 15, an air inlet port 16, and external upper threads 17. The barrel portion is provided with an internal annular ring 18, a lower positioning lug 21 and an upper positioning slot 22 which cooperate to position the various internal components of the device when they are inserted into the barrel portion. In assembling the components shown in FIGURE 2 the first component to be inserted into the barrel portion is the spray deflector positioning member 23 which is inserted into the barrel portion so that the recessed portion thereof 24 registers with the lower positioning lug 21 allowing the upper shoulder 25 of the member to seat against the lower annular shoulder of the barrel portion 18. The lower portion 26 of the spray deflector positioning member is internally threaded to receive the threaded stud 27 of the spray deflector 28 when it is inserted into the flared portion of the body. The next component to be inserted into the barrel portion during assembly of the device is the spacer member 31 which seats on the upper shoulder 25 of the spray deflector positioning member. The spacer member comprises a hollow cylinder having outside dimensions equal to the internal diameter of the barrel portion and has a diaphragm 32 with an orifice in the central portion thereof 33 and a positioning ring 34.

The next component to be inserted when assembling the device is the nozzle insert 35 which comprises a hollow cylinder having an upper outwardly extending shoulder 36 and a lower diaphragm 37 which has an opening communicating with a downwardly depending nipple 38 which forms a nozzle. Below the diaphragm is a lower inwardly extending shoulder 41 which seats on the upper ring 34 of the spacer member, the side of the cylinder and the lower inwardly extending ring being provided with a soap inlet slot 42 and an air inlet slot 43. An

outwardly projecting positioning stud 44 (shown by dashed lines) registers with the upper positioning slot 22 of the body portion to position the air inlet slot 43 opposite the air inlet port 16 of the body portion and the soap inlet slot 42 opposite the soap inlet port 45 of the body portion.

When these components are inserted within the barrel portion of the body and the internally threaded cap 46 is screwed onto the upper threaded end of the body portion 17 the ball joint 47 seats in the socket portion 48 of the nozzle member 35 to form a water-tight ball and socket joint for adjusting the position of the device relative to the water supply pipe 50. The valve plug 51 is provided with a slot 52 which, when the valve is turned to the open position, communicates between the soap inlet port 45 and the interior of the soap reservoir. An

. internally threaded cap 53 is provided which is adapted shown) and terminating at its lower end in a head 54 and means generally indicated by the reference character S for introducing a liquid soap into said conduit at a point intermediate the ends thereof, and includes the improvements in combination with such a device comprising an air inlet port 55 communicating between the outside and the inside of the conduit, a first diaphragm member 56 transversely disposed within the conduit below the air inlet port 55 and the point 57where the liquid soap is introduced into the conduit, the first diaphragm member having an orifice 58 in the central area thereof, a second diaphragm member 61 transversely disposed within the conduit above the air inlet port and the point of soap introduction and spaced above the first diaphragm member to form there-between a soap-air mixing chamber 62, the second diaphrgam member having an opening 63 in the central portion thereof communicating with a nipple 64 depending downwardly therefrom to form a nozzle for injecting water through the orifice 58 and the lower diaphragm member 56, the lower tip of the nipple being spaced above the plane of the upper surface of the lower. diaphragm member to entrain a soap-air mixture from the soap-air mixing chamber, means for releasably attaching a liquid soap reservoir to said device comprising a cap member 61 integral with said device having a threaded recess 62 therein adapted to receive a threaded male spout of the soap reservoir, a soap supply port 63 communicating between the interior of the conduit and the threaded recess of the cap member, and valve means 65 (shown with the valve plug removed) disposed in the soap supply port for interrupting and adjusting the flow of liquid soap from the soap supply reservoir into the soap-air mixing chamber, and a liquid soap supply reservoir 66 comprising a receptacle having a threaded male spout 67 adapted to'connect into the recess of the cap member, the spout having a hole 71 communicating with a dip tube 72 depending downwardly therefrom into the interior of the soap reservoir, the hole sealably registering with the soap supply port when the male spout is seated in the recess of the cap member. To provide for air to enter the soap receptacle to replace soap as it is withdrawn, the threaded male spout is notched as shown by the dashed lines to permit air to enter under the cap member and flow into the interior of the soap receptacle. FIG. 4 shows in greater detail the cross section of the portion of the soap supply conduit containing the valve means. The valve means comprise the valve body 73 with soap inlet port 74 and soap exit port 75 and the valve plug 76 (shown with handle removed) shown in the open position with the slot in the valve plug communicating between the inlet and outlet ports.

The device herein described is conveniently made from a molded plastic or can be machined from any suitable metal. It will be understood to those skilled in the art that minor modifications of the shape of and the number of parts can be made without departing from the spirit of the invention which is defined in the appended claims.
