` E. A. CLAUDER SHAMPOO APPARATUS Filed oct'. 25, 1957 Patented Nov. 28, 1939 amr-Eo STATES SHAMPOO APPARATUS .Earle.A..Clauder, Madison, Wis., assigner to Ever- Flo Manufacturing Company, Inc., a ,corporation of Wisconsin `Application,October. 25, 1937, ScrialNo. 170,925 l 3 claims. (ci. 299-144) This invention relates to improvements in 4shampoo apparatus, Yand moreespeeially inappa- Aratus designed '-to supply both water and liquid .soap vto the head.

The :present application is a continuation-in- :part of my application, `Serial No. 146,687, -ed June 5, 1937.

One feature of this invention is lthe Aprovision of a deviceaadapted to be held with one hand and designedforquick dispensing' of either water or soap, orbOth, the control oi' such dispensing being by the thumb of said hand withoutthe'necessity-oi shifting the hand; another feature of this invention is the Iprovision of means vfor heat eX- change between warmwater and the liquid soap so that saidlsoapmay beapplied -to the head in a warmed condition; yet another feature of this invention is the provision'ofV an annular nozzle'for the -wate-r supply, with -the soap `nozzle yso -arranged as to discharge soap within the area 'bounde'd'by said annular nozzle; a 'further feature of this invention is the provision of an improvedcontrol valve; other features and advan-V tages Vof this invention will be apparent from the following speciiication and the drawing, 4in which: l

. lg. (l is a side elevation,A partly broken away, cf lshampoo .apparatus embodying this invention; Fig. 2 isa vertical sectional AView of the handle and associatednozzles land valves; Fig. 3 vis .atop plan view of the handle of Fig. 2 and Fig. 4 is a bottom vkplan View of -the -nozzles and a portion of the handle.

In connection with the shampooing of. hair, and particularly -womens hair, it is desirable to have a convenient supply -of both warm water and soapso arranged that they may be used individnally, intermittently orsimultaneously. It is also oi considerable advantage if the dispensing apparatus vfor the soap andwater can-be operated byone hand, leaving the other .free to` adjust a towel, work the soapor waterginto the hair, and otherwise care'for the-needs ofthe :person whose head is being shampooed.

The application oi cold liquid soap (and soap atfroomftemperature,may be thus considered in comparison with the warm water used) to a head after preliminary rinsing with warm water is uncomfortable to the patron. Moreover, relatively cold soap does not lather as well as warmed liquid soap. My shampoo apparatus, therefore, provides means whereby the soap supply can be warmed substantially to the temperature of the water so that its application to the scalp causes no unpleasantness, andthe conversion of the soap into va'lather is facilitated. y. It has yalso been found that the use of vanannular nozzle is .of `considerable advantage, ysince it provides good distribution of va plurality of 4small .jets ofvwater. flthas alsobeen found kan advantage toy-.supply the liquid soap .to the hair within the area or space bounded by the annular nozzle, or the jets of water issuing therefrom, Yso that more soap canlbe placed -on the hairpeven when Hthe water is flowing `full force from `an annular nozzle, without Sits being immediately washed away and-lost. l

In'thefparticular.embodiment of my invention illustrated 'herewith `a vsubstantially cylindrical handle VIt! is shown provided wtih an annular nozzle I-I adapted to discharge'water,and-aseo# ond nozzle l2 adapted to discharge-soap. Convenientime'ans for supplying both-soap and water to the handle, land'thus to the nozzle, is here vshown as eomprisinga main Yhose I3 adaptedto be coupled'to a conventional faucet M by any convenient means, and a second smaller hose 'l5 adapted to @have liquid-soap gravity fed there" through from ian elevated soap container i6, which may, for example, be mounted'on a wall as by the bracket I1.

The handle Il] has formed therein two distinct chambers, :l-iland i9, here vshown as concentrically arranged. The chambers are not in communication with each-other, but are in heat transfer relation so that the liquid flowing through the chamber iE, namely warm water, can transfer heat tothe liquid in the chamber i8, such as soap.

The chamber I9 receives water fromlthe large hose i3 y,and passes-it into the end chamber 42i?, which `is adapted to communicate with the annular nozzle!! through thefopening 2l controlled by the valve member l22. The lchamber receivesl-iquid soap from the smaller hose l5, and is in communication-with the-nozzle l2 through the `opening orfpassage 23 controlled-by the valve member 26. The size ofthe soap chamber ll-ii'is ifo t suiiicient'that only'a portion of the soap'therein will-bev dischargedthrough the nozzle i2 at any givenftime;Y thus insuringsuiiicient 'length V'of stay of "the soap inthe chamber l8'that'itapproaches the temperature of the warmwater flowing through the chamber or passage i9.

The valve controlling the communication of the chamber I8 with the nozzle l2, and thus the flow of liquid soap therethrough, is of the normally closed type adapted to be held in open position only by manual pressure on the button 25. That is, the spring 26 urges the valve 24 into closed position, and as soon as pressure is removed by release of the thumb from the operating button 25 the valve at once returns to this closed position.

The valve member 22, on the other hand, although provided with a spring 21 urging it into closed position, is provided with mechanism whereby it may be manually operated and locked in open position if desired. This mechanism comprises a lever 28 cooperating with a stud or member 29. The lever 28 is provided with a straight portion 30 connected to the stem 3l carrying the valve member 22 a portion 32 inclined or angularly disposed with respect to the direction of the motion of the valve member 22; and a portion 33 adapted to be contacted by the thumb of the user. The stem 3l and valve member 22 are rotatable about an aXs coinciding with the stem 3|, and thus with the direction of movement of the valve member 22. Since the lever 28 is carried by the stem, it is similarly rotatable, and downward pressure upon the portion 33 of the lever (speaking with respect to the apparatus as shown in Fig. l) efects movement of the angular portion 32 with respect to the member 29 in contact therewith, which movement results in displacement of the member 22 from its seat to open the valve. The angularly disposed portion 32 is provided with a depression 34 adap-ted to receive the member 29 when the valve is fully open in order tolock it in that position, so that the thumb may be removed. Thus, even when the water is owing from the annular nozzle, soap may be supplied to the head of the person being shampooed by manipulation o-f the button 25. On the other hand, when it is desired to stop the ow of water, the lever may be ilicked upwardly with the thumb,'causing a change in relationship between the angular portion 32 and the member 29 such that the valve member 22 may return to closed position under the urging of the spring 21. It will be noted, as may be particularly seen in Fig. 3, that the operating portion of the lever and the button 25 are so arranged that they may be selectively operated by the thumb of the hand holding the handle IB without any necessity for shifting the position of the hand, or using the other hand.

In operation, thek valves controlling the flow of water through the faucet Ill would be adjusted to provide water of the desired temperature. The lever 28 would then be moved to a position permitting flow of water from the openings 36 in the annular nozzle 3B, and the hair would be given a preliminary rinse to warm and wet it. The flow of water may then be discontinued, if desired, and sucient soap dischargedV from the nozzle I2, by operation of the button 25, to enable a lather to be worked up in the hair. A ow of rinsing water could then be again used from the nozzle ll, under control of the lever 28. Moreover, water and small amounts of soap may be simultaneously applied to the hair, if desired, to insure a moist lather. It will be noted that the discharge of both soap and water is fully under the control of the hand holding the shampoo apparatus, with no necessity for manipulaprior art.
