INVENTOR. mal;

A TTORNE Yf Patented Feb. 9, 1932 UNITED STATES ARTHUR L. BOIBRICK, OF LOS ANGELES, CALIFORNIA SOAP DISPENSER Application led April 9, 1930. Serial No. 442,804.

This invention comprehends the provision of an improved type of soap dispenser, preferably adapted for dispensing liquid soap, and including improved means for irremovably supporting a dispenser on a wall or supporting surface, and a valve mechanism for dispensing the soap therefrom which is bodily removable from the receptacle.

Another object is to provide in a soap dispenser, a receptacle, a dispensing valve mounted on the receptacle, means for attaching the dispenser in position for use, and means rendered edcctive by the assembly of the valve on the receptacle for irremovably locking the receptacle in position, except by authorized persons.

Another object includes the provision of a suitable key adapted for use for authorizedly removing the receptacle when desired.

Another object is to provide a specially formed attachment plate held on the rear of the receptacle and arranged to irremovably hold the receptacle in position for use on a supporting member, together with an improved type of filling cap and means for attaching the same to the receptacle.

Other objects may appear as the description progresses.

In the accompanying drawings I have shown a preferred form of my invention subject to modification within the scope of the claims, withoutdeparting from the spirit thereof.

In said drawings,

Fig. 1 is a perspective view of a dispenser embodying my improvements, as seen from the rear side thereof.

Fig. 2 is an enlarged sectional elevation of the same on line Q--Q of Fig. 1.

Fig. 3 is a transverse section of the dispensing valve on line 3 3 of Fig. 2.

Fig. 4.- is a perspective view of the key suitable for attaching and removing the valve from operative position.

Fig. 5 is a transverse section of the attaching means for the dispenser as seen on line 5--5 of Fig. 1.

Fig. 6 is a section of the filling cap on line t-G of Fig. 2.

In its preferred form my dispenser includes a sheet metal receptacle 1 of suitable form and provided with an enlarged encompassing base portion 2 and a front vportion 3 within which is a single compartment 4 adapted to contain a quantity of soap. The compartment 4 is closed by a pan like bottom 5 which is welded or otherwise suitably attached to the flat portion 6 of the base, and has an encompassing flange 7 which is similarly secured to the flange 2 of the base. The bottom thus nests snugly in and is irremovably secured to the base 2 and provides a shallow compartment 8 inwardly of the bottom which is closed on its rear side by the surface of a wall or supporting surface 9, to which the receptacle is adapted to be attached for use.

Centrally of the back or bottom 5, I provide a vertical attaching plate 10 which has a foot 11 on its upper end adapted to be welded or otherwise permanently secured to the back, while the portion of the strip below the foot is bent outwardly and is spaced slightly from the back 5. The lower end of the strip 10 is right-angularly bent outwardly at 12, and intermediate the portions 11 and 12 a pair of bayonet slots 13, 13 are formed in the strip 10. Said slots have enlarged circular extremities 14 at their bottoms and elongated portions 15 at their tops. The portions 14 are of suliicient size that the heads 16 of screws 17 may be inserted therethru into the space between the back 5 and the plate 10. A pair of longitudinal ribs 11', 11', are formed in the plate 10 so as to render the plate rigid, as hereinafter explained.

When the receptacle is forced downwardly over the heads of the screws 17 the bodies of the screws will seat in the upper extremities of the portions 15 of the slots while the heads will seat in conical depressions 18, as seen in Fig. 5, which are formed at the upper ends of said slots.

The ribs 11 on the attaching plate 10 serve to strengthen the plate longitudinally so as to prevent the buckling of the plate intern mediate its ends and to uniformly engage and support the receptacles on the screw heads 16. 1Were said ribs omitted the plate would bend in the middle to such an extent that it would be possible to detach the receptacle from the screw heads and the ribs are safeguards against such an act. l

Near the bottom of the receptacle 1 I provide a dispenser valve which is mounted partly within and partly without the compara` ment 4 on the front19 of the receptacle. Said valve includes an internal barrel like body which is closed at its inner end bymeans Vof a screw 21 which is tightly threaded into the rear end 20 thereof. Said Vscrew extends thru apertures in the back 5V and plate 10 and is preferably provided with a square or"heX agonal head 22 positioned adjacent the portion 12 of plate 10 so that one of the flats on lthe head wil-l tightly fit against the portion -12ofthe plate. rlhus thescrew 21 is prevented from turning inthe members 5 and Y .apart,wherebythe soap fromcompartment 4 may enter the cylinder 23.` The rear end 2O ofthe barrel 2O has an outer end portion 2G which projects thru and substantially outwardly from the .front wal-l 19 of the receptacle and is externally threaded, as shown in Fig. 2. The valve further includes a cup shaped cap27 which has a cylindrical body 28 with Va bore 29 therein. kSaid bore is vclosed at the outer end of the cap by means of a wall 30, and a conical iiange 31 is provided at the inner end ofthe cap which rests against the front wall 19 of the receptacle. The'invner portion of bore 29 is internally threaded at v532 to receive the externally threaded portion 26 .of the barrel 20. The flange 31 en- 'closes and compresses a washer 31 against the front 19 of the receptacle and also radially aroundthe'portion 26 of the valve bar-V rel, and thus prevents leakage.

Vlvhenthe valveis being assembled, the barrel 20 is'tightly screwed into the cap 27 with -a cage 33 and washers 34 and 34 interposed between the outer end of the barrel andthe wall .as shown. Cylinder 23, however, has a lpiston 35 reciprocally'mountedtherein and urged outwardly to the end of the cylinder' .by means of acompression spring 35 which is held in compression between thepiston and tthe portion 20 of the barrel. Said piston ihas astem 36 riveted or otherwise permanent- .ly attached. thereto, which extends r thru a -bore37of cage 33 and a corresponding bore in theendBO ofthe cap. Y

A suitable knob orfiiange-SSS is formed von or attached to the stem 36and serves as an operatingA member for the piston. Thus, when the piston is forced inwardly against 'the 'tension of spring 35 until it reaches a Jposit-ion intermediate the orifices 24 and'25 of 'the cylinder', the liquid from compartment 4V offthe receptacle Vwill enter that portion of "the cylinder outwardly of the piston, and the tension of spring 35 when pressure on the member 38 is released will restore the piston to its normal position, as shown in Fig. 2.

The stem 36 just forwardly of piston 35 is provided with a wide annular groove 39 which forms an annular compartment in the boreV *37y of member 33 when the piston is in normally outward position. The cage 33 -also .has an annular groove formed therein to provide a chamber within the cap 27, and said 4chamberhas a single outlet 41 on thelower side of the cap. The chambers 39 and 41 are permanently in communication by means o'fvone or more orifices 42 formed in the cage 33, as shown in Fig. 2. Thus when vthe Apiston is forcedinwardly -to va maximum extent the forward end "of thecylinder 23 is charged with a quantity of liquid from the compartment 4, and the ensuing outward -movement of the piston forces said chargev of liquid into the'bore 37 of the cage and thence outwardly thru orifices 42 into chamber 40, and finally outwardly thru the single orifices f41 inthe cap. When the piston is forced inwardly against Ythe-tension of spring 35 any liquid which is present in the cylinder A23isevacuated thru orifices 24and 25.

In assembling Vthe dispenser, when the dispenser l isloosely mounted on the heads 16 of screws 1'?, as hereinbefore described, theV piston, piston stem, and cage are then mount- ;ed in the cap 27, whereupon the barrel 20 is tightly screwed into the cap so that it will be incapable of removal therefrom except Vby authorized persons orby persons who are :familiar with the manner of assembly. The assembled dispenser valve is then bodily insertedthru'the aperture in the receptacle 1 and turnedin a given direction so asy to screw 4the barrel20tightly upo'ntthe screw 21. Y

When this is done the tightening of the screw 21on the barrel 2O will draw the plate 10 tightly against the back-5 or awasher 43, which may be interposed between the back Vand the plate, so that itwill be impossible to move the receptacle over the heads of screws '17 Aand therefore impossible to remove the receptacle from the supporting surface 9 without unscrewing the cap 27. Neither .the

members 20 or27 are provided with flats or means for attachment of ordinary'wrenches or implements thereto, whereby said members may be unscrewed. The washer 43 prevents leakage of the soap aroundthe bolt 21. j

The outlet/41 ofthe cap, however, protrudes substantially from the periphery of 'the cap and provides a means of attachment for a special type of wrench 44, which'may be applied to the cap for removing it. V,Said

nwrench is lshown in Fig. 4, and in brokenlines l in Fig. 3, and includes ahandle 45'w1th a hook 46 formed at one end thereof adjacent a recess47. y

Vhen the wrench is applied to the cap 27 for attaching or removing the same from operative position the hook Li6 is inserted in the outlet l1 while the recessed portion 47 rests against the periphery ot the cap. As seen in F ig. 3, when the wrench is turned in a clockwise direction it will tightly screw the cap 27 into operative position on the receptacle. Uien the wrench is placed in a reverse position on the cap it may be employed ttor unscrewing the cap.

The vibrations 4G and 46 of the wrench l5 may also be employed as a gage for setting the screws 1G so that the heads of the screws will be positioned at equal distances from the .tace of the supporting member 9. In such case the recess 1li" between said vibrations engage the bodies oil the screws 1G and the screws are then screwed into the member 9 so that the heads will engage the outer surface ot the wrench.

The receptacle l may be filled with liquid thru a sleeve 48 which is irremovably held in the top i9 ci' the receptacle. Said sleeve .has a spring held cap 50 enclosing the upper end thereof, which is mounted on a hinge pin 50. rihe sleeve has an annular reduced portion. l which engages the opening in the top i9, and also embraces a flange 52 overlying the top oit the receptacle.

'.lhe sleeve below the portion 5l is normally straight so that it may be readily inserted in the opening' in the top and is then rolled annularly and expanded at 53 so as to underlie the top of the receptacle to prevent the removal et the iilling cap. rI'he top L i9 of the receptacle may be provided with a plurality oi recesses i9 around the opening therein so Athat when the portion is expanded the recesses 4:9 will be partially iilled with the metal forming the annular portion 5B so as to in'event the turning of the cap in the top.

llrom the foregoing description of my imprfrvements it will be observed that I have provided a simple, e'llective, and economical dis'iensing mechanism tor liquid soap or for other materials which is ordinarily incapable oiE removal for extracting the contents thereoit' witlmut linowledge of its manner of assembly and possession of the special type of wrench tl-fi necessary for suoli purpose. In any event, one seeking to remove the receptacle in an unauthorized manner must know the secret oi the combination between the several elements which combine to hold the case in position on the surface 9 and to remove the .ip Q7 from the receptacle.

While I have shown a suitable form of valve for use in connection with my receptacle, it will be understood that any other suitable torni oi' valve may be employed. The essential characteristics oiE the valve are such that the valve may be bodily assembled, inserted in and removed 'from the receptacle, and that the valve may not be removed by the application oit an ordinary wrench or tool, 'for the reason that a special type ot' wrench is required. The opening il which received p0rtion 46 of the wrench is so formed that a nail or other straight tool will not be eilective for turning the valve cap :28. rlhe washers 3l and 43 prevent leakage of the contents thru the openings for the valve barrel and the bolt 21.
