SOAP DISZENSER Clecphas Mcvicker, Cincinnati, Ohio Appiication November 4, 1931.

3 Giaims.

This invention relates to a dispenser for powdered soap and like materials and has for its principal object the dispensing of powdered soap in uniform quantities and in such manner as to preclude wasting of the soap and to assure constant and unvarying dispensing thereof. Another object is to provide such a dispenser which operates by revoluble means rather than by means of a push rod or the like heretofore commonly in use.

Another object is to provide a dispenser.

equipped with means for agitating the contents of the container upon each operation of thedispensing mechanism.

Another object is to provide a device of the kind described which may be readily adapted for dispensing lesser or greater quantities of the dispensed material.

Another object is to provide an efficient dispenser of the kind described and adapted for simple operation and low cost manufacture.

These and other objects, are attainedby themeains described herein and illustrated in the accompanying drawing, in which:

The commonest forms of soap dispensers heretofore in use have utilized push rods or similar means for effecting dispensing of the soap. Disadvantages of this type of mechanism lie inthe fact that the dispensing is frequently retarded or stopped due to the fact that the powdered material becomes caked within the container or within the closed parts associated with the dispensing mechanism. In instances of this kind, the push rod is ineffective for re-establishing operating of the device since said rod would merely pass slidingly through the caked material without moving it orbreaking its caked formation. Hence it is necessary to disassemble the dispensing means in order to render it operative. Another difficulty encountered has been the use of such dispensing means with powdered soaps of the lighter flaky kind. This kind of soap, though in itself desirable as a dispensable soap, yet due to its of gravitational force was difficult of use due to the restricted passages forming parts of the dispensing mechanisms heretofore used.

The present invention overcomes these diffi- Serial No. 572,986

(Cl. 221--lil8) culties by providing a dispenser which effects direct gravitational feedof the dispensed unit quantities of soap and witha minimum of contact with the dispensing mechanism. In addition the entire mass of soap both within the container and within the dispensing portions thereof, isagitated and moved upon each operation of the device so that there is no possibility of caking or of portions of the soap becoming-lodged in parts of the dispensing mechanism and of the container where no means is provided for releasing such portions. Moreover, due to the direct gravitation feed of the soap in the present dispenser, the lighter kinds of soap are as easily and efficiently utilized as the heavier types of powdered soap.

With reference to the drawing: the device comprises a container 1 which terminates at the bottom with an open neck 2 and which at the top may be provided with a refill opening and cap 3. The neck 2 may be exteriorly threaded in order to receive a cover member l which has fixed thereto a support arm and bracket 27 adapted to be secured to a wall surface for supporting the dispenser. The surface portion 5 of the cover is provided with a central aperture 6 and off-center segmental aperture 7. It is desirable that this aperture 7 be positioned at the front of the container and slightly to the right as indicated in Figs. .2, 3, and 6. Upon the upper face of the cover 4 an inverted cup member 3 is positioned. This member has its side walls in close relationship with the inner surface of the neck 2 of the container and may be provided with an edge flange 9 which is adapted to be clamped down upon the surface 5 by the edge of the neck 2 which is threadedly tightened upon said flange. Such positioning of the cup member is ordinarily suflicient for retaining it immovably in proper operative position. However, the flange 9 may be secured to the surface 5 by soldering at one or two places or by other suitable means. The surface portion, side wall, and flange of the cup 8 are cut to" provide the inlet aperture 10. In addition the cup is provided with a central aperture 11 adapted for vertical alignment with the aperture 6 of the cover 4. The cup is so positioned, upon the surface 5 of the cover that the aperture 10 is disposed at the opposite side of surface 5 relative to the aperture '7.

Within the cup 8 a star wheel 12 is revolubly positioned. Said star wheel is carried by a pair of screw bolts 13 which pass through the hub 14 of the star wheel and which pass upwardly through the aperture 11 of the cup in non-contacting relation therewith. The washer 15 separately receives each of the bolts 13 and is adapted to rotate upon the surface of the cup member, small nuts 16 serving to lock the bolts in place. These nuts may likewise hold in place theends .one .shown in Fig. 2.

of a wire agitator 17 which preferably is formed to stir the remoter or outermost contents of the container where caking is most liable to occur. Below the star wheel 12 the bolts 13 pass through a washer 18 of greater thickness than the surface portion 5 of the cover member and the heads of said bolts are countersunk in the hub portion 19 of the operating wheel 20. The edges of isaid wheel project outwardly beyond the cover -4 so that the wheel may be readily rotated for effecting dispensing of the soap. The spokes 21 of the wheel are adapted to be positioned immediately beneath the arms 22 (Fig. 3) of the star wheel. This relationship is maintained by virtue of the pair of bolts 13 which render the wheel 20, washer 18, star wheel 12, washer 15,. andagitator 17, 1'0- tatable as a unit. It will be seen in Fig. 2 that the opposite surfaces of the washer 18 serve as .a bearing for the hubs of the star wheel and the operating wheel respectively.

.By reference toFigs. 2, 3, and iit will'beseen carried in limited successive quantities .by the arms. 22 of thestar wheel and-movedaround uponthe surface 5 until it is dispensed by said arms through 'the aperture 7 of the cover. :I-Ience the arms 22 intermittently receive and dispense a limitedquantity of thepowdered soap. It is obvious that the star wheel of the carrier mem- .ber/maybemade-of differentthicknesses in or- -'derto carrya greater-or lesser amountof soap, it being clear thatthecarrier of lesserzthickness .will receiveand deposit. a smalleramount of soap thanthecarrier of greater thickness such as:the Furthermore this carrier -member may be modified .in form such as .illus- =trated-inlFigu7 in which aplatemember=23 is -shown, said member being provided with a plurality of perforations 24 each adapted toreceive andcarry a small amount. of powdered material. A regular andlcalculated.rotationof the operating wheel may beeffectediby the .use of a springstrip 25 secured=upontheside of .the cover members-as shownin Fig. 1 and :havinga free end adaptedtoride upon theouterportionofthe upper surface of wheel 20. The latter surface portion is=formed with depressions 26 so disposed relative :to the .arms 22 of :the carrier that when each of said arms is in the depositingposition, the endof the spring strip 25 issnappedinto one of the depressions 26.

It ,will1be seen that thedeviceof 1thisinvention ;is.readilyassembledand disassembled. The dis- ,pensinaunitimay'b epar ly pu to ther and :thecontainer screwed down into ,place within the .cover 4 until it [rests uponthe-flange 9 of the cup member asshown. The powdered material may .now be placed inthe containenthe mass thereof ,resting-uponthe uppersurfaceof the cup 8 and constantly feeding downwardly through the'aperture 10 therein whereby the spaces-between the arms-ofthecarrier are filled with uniformquantitles of soap. It will likewise be seen in 'Fig. 2 ;that th 8 portions of the-agitator '7 adjacent the finds thereof may be formed ;-into parallel adjacent relationship with the surface of the cup member so that-the powdered soap resting thereon is constantly moved about. The operating wheel 20 may be rotated in either direction with out varying the dispensing operation. Another efficient feature-of this deviceis that the operating wheel is adapted to be rotated and a unit quantity of soap dispensed by one operation and with one hand of the person using the dispenser. This is an advantage over the dispensers commonlyseen which are provided with levers operated by one hand while the other hand is held beneath the dispensing aperture. The device of '.this invention is adapted to be positioned so that .the natural position of the hand grasping the operating wheel is such that the palm of the handisdisposed directly beneath the dispensing aperture.
