This invention relates to a liquid dispenser and more particularly to a dispenser of the spray type such as a shower head.
An important object of the invention is to provide means for selectively delivering either plain water or a mixture of water and liquid soap from a device which may be readily attached to a water supply pipe.
Another object of the invention is to provide a contro1 for regulating the amount of soap supplied to the water and to provide means for causing the water pressure to supply the soap through the control means to the water.
A further object of the invention is to provide a single control means for simultaneously regulating the flow of plain water through the device and regulating the flow of mixed water and soap through the device.
Another object of the invention is the provision of such a dispenser which is simple and inexpensive to manufacture and easy to install and service.
Other objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings, in which:
Fig. 1 is a view illustrating an adaptation of the improved device to a shower fixture;
Fig. 2 is an enlarged sectional view of the dispensing unit shown in elevation in Fig. 1;
Fig. 3 is a fragmentary sectional View taken on line 3-3 of Fig. 2; and
Fig. 4 is a fragmentary sectional view of the valve, shown in Fig. 2 in its normal closed position.
Referring to the drawings, the improved shower head comprises an outer casing I and an inner casing 24. The inner casing 24 is detachably received on the open end of a Water supply pipe I2, by a threaded coupling 14 which surrounds the neck portion IS the latter having an annular flange i8 fitted Within the coupling [4. The coupling i4 is threaded on the end of the pipe l2 drawing the flange [8 into sealing engagement with a gasket 20 which bears against the end of the pipe l2.
The body casing ID is formed such that it surrounds the casing 24 thus providing a compartment 22 surrounding the bell-shaped casing member 24 the latter forming the inner wall of the compartment. The bell-shaped member constitutes a liquid discharge passage, the open end of which is covered by a convex plate 26 perforated for discharging the water or water mixed with soap in the form of a shower spray. The compartment 22 is provided with a filling opening 28 which is shown screw threaded to receive a threaded plug 30. A Vent 3| is provided in the plug 36 to admit air to the compartment 22 when the liquid soap is drawn out of the compartment.
The bell-shaping casing member 24 is preferably formed from sheet metal by stamping or spinning and is shown as an integral part with the neck Hi. The casing H] has an outer wall 32 and an upper surface 34 also formed from sheet metal by stamping or spinning. The upper surface 34 is provided with an opening 36 of a diameter great enough to slip over the flange l8 and its peripherial edge is secured to a shoulder 38 between the upper portion of the bell 24 and the neck IS. The lower edge of the outer wall 32 is secured to the lower edge of the bell 24.
A tubular conduit 46, coaxial with the bell 24, has its lower open end flared, as at 42, and may be secured to the plate 26. The opposite end of the tubular conduit 46 terminates within the neck I6 of the bell 24 and is open to the water passage through pipe l2 so that water may flow through the tube 46 discharging through openings 44 in the plate 26. When the valve i6 is open water may flow through the bell 24 discharging through openings 46 in the plate 26.
oppositely disposed cylindrical bearings 48 are secured to the wall of the tube 46 adjacent to but spaced from the upper open end of the tube 40. The wall of the tube 46 has openings 50 which register with the inner periphery of the bearings 48. A cylindrical valve member 52 is rotatably journaled in the bearings 48 and has earns 54 and 56 at its opposite ends. The cam 54 may be integral with the cylinder 52 and the cam 56 is detachably received on the end of the cylinder by a screw 58. The earns 54 and 56 serve to position the cylinder 52 axially within the bearings 48 by engagement with the ends of the bearings 48. A control rod 6!! is secured to the end of the cylinder 52, opposite to the removable cam 56, and projects through the wall of the bell 24 and the outer wall 32, the latter being sealed to prevent the escapement of fluid. The outer end of the rod 60 is provided with an arm 62 for turning the cylinder 52 within its bearings. A coil tension spring 63 has its opposite ends secured to the tube 46 and cylinder 52 respectively to normally hold the cylinder 52 in a closed position, illustrated in Fig. 4.
The cylinder 52 is provided with a Venturi passage 64 extending transversely of the cylinder forming a conduit between the opposite ends of the tube 40 when in the open position, shown in Fig. 2. Fig 4 illustrates the cylinder 52 in its closed ment 22. A transverse passage 68 in the cylindrical valve 52 having its axis extending at right angles to the axis of the venturi 64 forms a com munication between the upper end of the tube 66 and the venturi 84 when the cylinder 52 is in the position shown in Fig. 2.
A sliding valve 70 is mounted-on the upperend of the tube M] and rests on the surfaces of cams 5t and 56. Its upper surface, when in closed.psi tion as shown in Fig. 2, seats against theperipherial edge of the shoulder 38 closing the passage through the bell 24. When the cams 54 and 56 and the cylinder 52 are turned to the position shown in Fig. 4 the valve 70 falls away from its seat and permits Water to flow through the bell 24.
Referring to Fig. 2, the arm 62 is in a position for closing the valve F0, aligning the axis of the venturi coaxial with the axis of the passage in the tube stand positioning the axis of the'passage B3 in alignment with the opening in the upper end of the tube 6t. This shuts off the flow of water through the bell 213 and permits a flow of water through the tube 49 and venturi 64. The flow of water through the venturi produces a suction in the passage 58 and tube '66 thereby'drawing liquid soap from the compartment 22 into the Water stream, The discharge'of water mixed with soap is through the perforations 4 L When the required amount of soapy water is discharged, the arm 52 is released and the spring 83 moves the cams 5d and 58, valve 19, and cylinder 52 t0 the position shown in Fig. 4. The water passage through the tube 40 is then closed and 'waterflows through the bell 24 discharging through'the'perforationsfi.
The device is operable by a single means for controlling at will the discharge of plain water or the discharge of water mixed with soap. The construction and simplicity'of parts'pe'rmits easy assembly and the cost of manufacture is inexpensive.
It will be understood that various changes includin the shape and arrangement/of parts may be made without departing from the 'spirit'of our invention and it is not our intention to limit its scope other than by the terms of the appended claims.

A shower head comprising inner and outer casing portions disposed in spaced concentric a'ssembled relation to thereby provide a water compartment and a soap compartment, means for filling the soap compartment, means for attaching the assembly to a water pipe, a water discharge tube disposed within the water compartment and communicating with the water pipe, means providing communication bt'ween'the soap compartment and the discharge tube including venturi means for inducing flow of soap, and valve means operable to cause water from the water pipe to flow through said discharge tube or through said water compartment.
