3 Claims.

invention relates to improvements in'soap ejecting spray heads. v

1` Heretofore, beauty parlor operators and barbers", whenshampooing a patrons hair, have been sil forced tofutilize soap from a separate bottle or cake; and it hasl been necessary to rst apply the soap, then to replace the bottle or cake of the latter, and` then to pick up the water spray head; This inconvenient change must be made m several times before the shampoo is completed.

Furthermore, with present day methods, the liquid soap is relatively cold while the water being used is warm.` Thus the patron is subjected to to the discomfort of temperature changes Aeach T515' time the soap is applied. It is one of the objects of the present invention to provide an improved spray head having means embodied therein for ejecting soap when desired, thereby eliminating the usual inconveniences referred to above.

A further object of the invention is to provide a soap ejecting spray head wherein the soap chamber is so positioned relative to the water inlet as to provide for warming'of the soap as the water passes thru said inlet.

A further object of the invention is to provide a device as above described which maintains the soap in a sanitary condition and which is economical in that it provides for discharge in controlled amounts as needed.

A further object of the invention is to provide a soap ejecting spray head which is simple in construction, inexpensive to manufacture, durable, and well adapted for the purpose described. With the above and' other objects in View, the invention consists of the improved soap ejecting spray head and all its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing illustrating one complete embodiment of the preferred form of the invention in which the same reference numerals designate the same parts in all of the views:

Fig.' 1 is an elevational view of the improved v spray head, showing a fragment of tubing conis preferably substantially bell-shaped; its lower end being normally closed by a dished plate" 9 formed with aV plurality of apertures IIIJ andi with a larger central aperture I-I". The apertures IU are for the discharge of water inshower form, and the aperture II is a soap ejecting' outlet, as will be hereinafter explained more-inA detail. The peripheral edge of the plate Bf is flanged around the flared lower'edge I2- ofl the housing as at i3, and the parts are then pressed together to maintain the plate 9 rmlyin-y position.

At an intermediate point within the housirigfis a horizontal partition I4 having a central apenture I5. A water inlet pipe IBhas its lower endl extending thru the partition I4 and held in place in any suitable manner, such as by a nut I6. The upper end of the pipe I6 extends thru the upper end of the bell-shaped housing 8 and is formed with a nipple I'I for the reception of one end of rubber tubing or the like I8.

The housing 8 is also formed near its upper end with an opening I9, there being a tubular boss 20 projecting from said opening. A cap 2| may be hinged as at 22 and may be normally maintained by suitable yielding means in closed position. By lifting up the cap, the chamber 23 above the partition I4 and surrounding the pipe I6 may be filled with suitable liquid soap.

A valve rod 24 within the chamber 23 is slidable thru an aperture 25 in a guiding lug 26 and has its upper end slidable thru an opening 21 in the upper end of the housing 8, said end being formed with an exteriorly accessible knob or button 28. Above the bracket 26 is a coiled spring 29 surrounding the valve stem 24, and a collar 30, fixed to the upper portion of the valve stem, is adapted to engage the upper end of the spring 29 when downward pressure is exerted on the button 28.

The lower end of the valve rod 24 extends thru an opening 3| in the partition I4 and carries a valve member 32 below said partition. Said valve normally closes a plurality of apertures 33 to normally prevent the flow of soap from the chamber 23. When the valve stem is depressed, however, soap can flow by gravity thru the apertures 33 into a valve chamber 34 and from said chamber thru a conduit 35 leading to the soap discharging aperture II of the plate 9.

In use, after the chamber 23 has been filled with liquid soap, the device is held over the patrons head in the usual manner. When the water is turned on, it will ow thru the tube I8 into the pipe I 6 and 'between the partition I4 and the plate 9. The water will then emerge in the form of a spray from the small apertures in the plate 9. After the patrons head has been suciently moistened, the water may be turned oi'l and the plunger 28 pressed downwardly to cause soap to ow from the discharge opening Il, or the soap may be ejected while the water is flowing, if more convenient. Thus, soap in any quantity may be discharged merely by pressure on the knob 28, and the relationship between the soap and water may be readily controlled thru the usual water control. Due to the fact that warm water is usually employed, this water iiowing thru the pipe I6 will tend to keep the soap in the chamber 23` in a warm condition or at substantially the temperature of the water; so that the patron will not be subjected to sudden temperature changes. This warming of the soap is also Very important, as it makes it flow more freely by gravity and facilitates lathering.

It may readily be seen that the device is simple toY operate, sanitary, and otherwise well adapted for the purposes described.

Altho only one form of the invention has been shown and described, it is obvious that various changes and modiiications may be made therein without departing from the spirit of the invention; and it is to be understood that all of such changes are contemplated as may come within Vthe scope of the claims.

What I claim is:

1. A soap ejecting spray head comprising a casing having an apertured lower end, a partition Within the casing spaced from said end and forming a chamber for liquid soap thereabove, means for admitting water to the space between said partition and the. apertured end for discharge in the form of a spray, a conduit extending from the soap chamber to the apertu-red end of the casing and communicating with the exterior, and means independent of the iiow of water for controlling the fiow of soap thru said conduit.

2. A soap ejecting spray head comprising a casing having an aperturedlower end, a partition within the casing spaced from said end and forming a chamber for liquid soap thereabove, means for admitting water to the space between said partition and the apertured end for discharge in the form of a spray, a conduit extending from the soap chamber to a central portion of the apertured end of the casing and communicating with the exterior, and means independent of the flow of water for controlling the iiow of soap thru said conduit.

3. A soap ejecting spray head comprising a casing having an apertured lower end, a partition within said casing spaced from' said end and forming a chamber for liquid soap there-
