Our invention relates to improvements in apparatus of the character set forth in our application 87,222, filed Februaryl0,1926,

'which has now eventuated, into Patent 5 1,717,417 dated June" 18, 1929. The main obj ect of' the invention is to simplify theconstructionhre'nder it more'durable and reliable and to facilitate the construction,adjustment and repair. Another object is to provide 10 means for regulating thewa'ter pressure.

reservoir for liquid soap .or other chemical 25 which it may be desired to mix with the water or. other liquid. For convenience we will hereinafter refer to the'liquidxas water and to the solution as liquid soap, or soap solution.

The outlet member at the bottom of the so casing is also connected with the interior of the soap bag'and providedzwith-a valveby which the passage of the soap solution to the outlet may be controlled. The 'soapbag is spaced apartfrom the bottom of the casing by a perforated raised platform, and a'control or throttle member is provided for regulating the flow of water from thecasing and hence regulating the pressure on the reservoir. The soap bag is detachably secured in th'ecasin'g between the platform at the bottom and the removable cover at the top. A tubular extension from the outlet member provides a convenient meansfo'r securing the cover in place. I 7

Fig. 5 is a'horizontal'sectional view of the outlet member onthe plane of the line 55 of Fig. 3.

Fig. 6 is a detail View of the regulating member.

The casing 10 may .be of any'suitable form andis ada'ptedto be'supported in any suitable manner, as forinstance, from the faucets 11 and12 for the hot and coldwate'r.

The nozzle or dischargemember 13'is preferably secured in'a suitable manner within a couplingmember l l'in sucha-mariner that thenozzle may beiswu'ng fromside to'side.

This coupling collar is preferably screwed on to the lower endrof an outlet member 15 whichin turn is secured in any suitable man ner in the bottomof thecasinglO." This outletmember has oneor more channels 16;extending vertically through itythrough which water may pass from the bottom of the cas- .ing. to the discharge nozzle.

The effective size'of the passages 16 may be controlled by the rotation of a regulating plate 17 whichis'mounte'd on the outletmember 15 within the casing and adapted to be set to provide any'desired: area of outlet. This plate 17 may be clamped'in' place by a screw 17 a in a slot 176'.

A perforated platform 18 is mounted on the outlet member 15 for supporting the lowerwall oflthe soapbag l9 and holding it spaced apart from the bottom of the casing so that water can pass around-the sides-ofthe casing to the outlet passageslG. The upper end of the I soap bag is preferably provided with a C'OllZII'QO adapted tobe seated around the mouth of the opening 21in the top of the casing. i

The upper end of the outlet member 15" preferably has" a" screw tl'irea'dedportion-22 which passes through an opening in the" bottom of the bag 19. The bag may be reinforced'by a washer 19a. The outlet. member its=upper endto its lower end' but is inter- 100 cepted by a passage for the valve 24 which has a transverse passage 25 through which the soap can pass when the passage 25 is in alignment with the passage 23. A small tube 26 is seated in the upper end of the outlet member 15 and provided with openings 27. A tube 28 is screw threaded interiorly at both ends and the lower end is adapted to be screwed on to the tip 22 of the outlet member 15 so as to clamp the bottom of the bag 19 against the platform 18 and hold the bag in place. This tube 28 is provided with openings 29 through which soap solution may pass from the interior of the bag through the openings 27 to the passage 23 in the outlet member.

The cover 30 of the casing rests on the collar 20 of the bag and is clamped in place by a knob 31 which has a threaded stem 32 which screws into the upper end of the tubular extension 28. Vhen it is desired to fill the bag theknob 31 is unscrewed and the cover 30 removed whereupon the bag may be filled by simply pouring the soap solution through the opening in the top. In case the bag is to be removed for repair or replacement the tube 28 is unscrewed using for this purpose the thumb pieces33, thus releasing the bottom of the bag which may be pulled out from the opening at the top of the casing. lVhen a new bag is to be inserted the hole in its bottom is registered with the inner tube 26 which serves as a guide while the bag isbeing inserted. The outer tube 28 is then placed over the tube 26 and screwed into place on the upper end 22 of the outlet member 15.

YVhen the apparatus is in use hot or cold water ora tempered warm water may be drawn from the nozzle 13 by proper adjust ment of the faucets 11 and 12. hen a soapy solution is desired the valve 24 is opened so that the soap solution can pass from the interior of the bag 19 through the openings 29 and 27 and the passages 23 and 25. The pressure of the water, hot or cold as the case may be, against the outside of the bag 19 serves to force the soap solution out at a rate which is substantially proportionate to the pressure. Vhen a soap solution is no longer desired the valve 24 is simply close-d so that "no more soap is admitted to the nozzle 13.
