LIQUID SOAP DISPENSER. APPLICATION FILED OCT. 19. 192 0.

Patented 0m 4, 1921 f, tr tium-soar msriinsnn To all whom z' t mci'j concemi 7 Be it known that WitmmrfigRosna citizen of the United statesand residing at Jersey City, Hudson county, State of New Jersey, have invented certain new and useful Improvements in Liquid-Soap Dispens- 1 ers, ofywhichrthe following is aspecifieation; V i r The present inventionjr elates to fluiddis-' pensers; particularly *to devices for dispens ingliquid soap, such as are .commonlyuse'd in hotelspoflice building's publi'cwash rooms and f en in private dwellings.

" Thesedispensers usually"on1prise'a container' or receptacle for holding "acQ'n idQ erable quantity of soap, in liquidform and a T manually "operable pumping device. by. means j'of which small measured quantities of liquid soap are withdrawn from the; container: and discharged into the out-stretched hand of the operator. [A common-defect of dispensers of'this'class heretofore designed or suggested is that an objectionable leakage of the-soap often occurs, this leakage being due in part to the nature ofjthe soap itself which will escape through minuteopenings and'cracks which are not large enough to allow the escape of water. When such leak- 1 age is detected itis, of course; necessaryto replace the defective parts or'the parts which do not fitptogether properly, and

where'jpistons .spr ngs, and other metallic parts are utilized such replacement may be.

difiicultand may involve. a considerableex ejecting action; which will not easily break" pense, as compared with the entire costof the dispenser. Leakage of soap in this 'manner renders the deviceunsightly.

g It is an object of the present invention to providea liquid soap dispenser having a pum ing devicewhich' is positive in'its 'down in use; and in which the component the container is' practically: eliminated; ren

V in anumber ofdifl'erent formsfa'nd several parts are of the simplest design,- enabling it to be made at a minimum cost thereby cut ting the expense of original installation and reducing the cost of; maintenance. The pumping device is. "so designed. and C011- structed' alsojthat leakage of the soapffrom dering it necessary to replacethe parts only when they are worn out through long continued use. The invention may be'embodied modifications. thereofgwill be described in penser and bracketbeing broken away to specification of Letters Patent. t nt 0 134, 1921, v Applicatio ni file'd October-1 19, -i920. serial 1w .'417,9e5'." 7

"Referringparticularly to Fig; 1 asupport 111g" bracket is indicated at 10- andfa glassor. metal receptacle or container at i ll, this a container "having an externally threaded tubular neck portion 12 at its bottom which screws into' the v correspondingly threaded upper 'end of a passageway 13 which extends vertically; through the outer end of the bracket. Immediately below the lower end i I i of neck 12th e passage, 13 is provided: with an upwardly facing annular shoulder- 14:

and am e tween the neck l2 and'this annular s oulder aretwosoft rubber members 15 and "16. The lower member 15.is

disk-shaped with a central 1 aperture 15" which opens into a contractile rubber .tube 15" extending verticall downward,lthe wall thickness of this tube being greater on one side than on the other, for a purpose here inafter torbe fully explained.

The upper 'member. 16 has an annular peripheral portion and cup or dome-shaped central portion having a central aperture and one orfmore inlet ports 7. ,A spindle 18 of -wood hard rubber, or other like material'extends downwardlythrough the container, "through thelcentral apertures in the rubber members 15 and 16, and through the contractile tube 15". A block'or diskli),

which mayfbe of cork or other, material is secured to this spindle immediately above the V the member 16, this spindle having handle or knob 20 at its upperend by means i of which it maybe conveniently grasped and vertically reciprocated. The upward move-a ment of the spindle is limited by a restrain ing member 21 which may have different forms, .but is preferably a .cord or tape the 1 ends of which are clamped between the neck 12 of the container and the diskmember 16 a the intermediate portion passing over block 19, and being wrapped around the spindle shaped rubber member beneath it.and, when' this has been partially Iflattenedserves as a valve, closing the ports 17. Further downward movement of the block creates pres-- sure within thepump chamber, the walls 1 of which" are formed by the two rubberv members, and thevsoap' therein" is forced out between the wall of the contractile tube 15" and the spindle 18, the tube 15 immediately contracting after the pressure is re-- lieved, preventing any flow of fluid dueto gravity alone. When the knob or handle is released, the member 16isprings back to its formeri shape "and returns the spindle to its initial position and the ports 17 are againjuncovered by the block, to permit the entrance of soap into "the mn chamber.-

Upon the return movement of the spindle and before ports 17 are uncovered by disk 19,

a suction may be created in the chamber which would tend to draw tube 15', up-

a rubber member 16' may be used if desired whichhas an elongated slot v17 in its. top. This member operates exactly as does the "member 16, the slot 17 taking the place of the small openings 17 of that member.

In the modification illustrated in Fig. 3,

the disk member 15 is ofhard rubber or fiber, and the cup shaped soft rubber mem ber 16 extends downwardly and'fit s closely within a similarly shaped shell or casing 30 which forms part of the bracket '10. A non-return valve 19 controls the flow through an inlet port in thedisk, this valve having a short "stem 18 attached thereto which extends through the outlettube at the bottom of the rubber memberlfi, Pressure is applied to the flexible wall of the pump'chamber by means of a horizontal manually operable plunger 31- and the'liquid is ejected between the stem '18 and theinner;
