, 8 Claims. (Cl. 222-130) M T R A .assignorto United L An el This invention has to do with dispensersfor delivering a metered, quantity of powderedpsoap-and the; like in response to manual actuation. The invention concerns espcciallythose dispensers in which the metering valve comprises a valve clementvertically reciprocable in a .valve opening at the bottom of the container for the powdered material.

A primary object of the invention is the provision of improved means for varying the amount of powdered material that is delivered oneach cycle of operation-of such dispensers. It is well recognized in thegart that it is desirable to providesuch variation of thedispenser action, since the requirements of diilerenpusers maybe quite distinct. However, previously available means for accomplishing such variationare otl -fully satisfactory.

- ;They tend,.-forexample, tobe inconvenient to; operate, subject to clogging with the powdered material, and difficult to set with assurance for. the desired-result: ,The present invention-provides a very simple and-straightforward mechanism that is readily adjustable, to give a selectedv delivery action with complete definiteness and i assurance.

= A further object of the invention is to provide an imdescribed type in a cabinet adapted to be set inthe .wall. One of the (iii- 1 ficultieswith such installation of .ahsoap dispenser, for

example, has-been that the soap that isspilled tendsto collect on the floor of the cabinet. A removable tray may be provided, to facilitate catching and removing such 7 l spilled soap, but the presence of spilled soap on the bottom of such atrayltends to beunsightly and objection- .able.

The present invention provides a special tray cover of novel construction, which hides suchspilled soap from the .view of the operator without obstructinglthe.freefalling of spilled soap to the bottom of the tray.

1 Certain. aspects of, the presentinventlon .are related to the structure describedand claimed inmy copendingpatent application, Serial No. 598,803, filed July 19 1956, 7 ,now Patent 2,906,578.

Valve mechanism 14 comprises a valve opening 16 in the bottom of container 12; a' valve chamber housing 15, at-

'tached to the bottom of the-container and forming a nite; states PareneQ Fiatented Nov. 14, 1961 "ice - valve chamber- 18 having delivery, opening 19 in its lower surface in alignment with valve, opening16 on axis 17;

which is guided for vertical movement by guide means each of which has an axiallaperture which fits slidably over the spindle shank. .Three such elements areshown illustratively, but a different nur'nber'may beprovided if preferredA collar-like rfiange,.26 is formed, near the lowerendi-of spindle 22, providingan upwardly facing should21whichsupports the valve elements and defines their-axial position on the spindle. A releasable retaining device is provided to hold the valve elements against the spindle. As illustrated, that retainer comprises a ,sp-ring clip 25- which isreceived in a circumferential channel in the spindle shankland shoulder 27 and prevent their upward movement along may be removed laterally to release thevalve elements. At least the lowermost of the Valve elementsfitl is limited, .by any suitable mechanism, to ,apredeterrnined angular position on the spindle.

, In the present embodiment a defining formation is pro- ,vided on the lower axial face of each valve element; and a formation of complementary form is provided on the jshoulder 27., Each of thefirst mentioned formations j typically comp rises a short pin or lug 31, and the com-' .upper face of each valve element and also on the face of plementaryforrnation .comprisesahole 32 adapted to re- 31. A particular advantage of that type of demechanism is that, in addition to defining the rotational position ofeach valve element, it insures that the .av e

I lements are assembled rightside up on the spindle. At the lower end of spindle 22 a handle 28 is fixedly .,mounted for manuallyreciprocating the entire valve asfrom valve axis 17 by means of the radial support, so

assembly) Handle: Z8 is preferably otlset 'rearwardly that a hand operating the valve will lie directly below delivery opening inposition to receive the released r soap.

G uide mechanism 40 pre-ferab-ly conforms the threefold function of guiding the upper end of spindle 22 in its vertical reciprocation, limiting the travel of that movelnientg and defining the rotary position of the entire valve assembly, 20. QThe'channel member 41 is fixedly mounted transversely. ofcontain'er 12, as by spot-welding, and is I provided with a shaped apertured 42 on the valve axis 17. spihdle iscutb'acl lfover a limited portion of its length t6 produce a non-circular sectionwhich terminates at opposed axiallyj facing 'shoulders. As shown in FIGS.

" 1. FIGS. .5 andfi --fQr l -a w of. the spindle, as by welding. Q paraxialfaee show modifications in the upper portion of,,the'spindle.l InFIG. 5 three paraxial faces 44a are retaining lug 46a is attached to the fiat end In FIG. 6 only a single 44b is present, and the downwardly facing ,surface directly opposes upwardly facing surface The upper end of the spindle is retained in aperture 42, and its reciprocating movement is limited in a downward direction, by a latch mechanism. In the present embodiment, that latch comprises the single latch member 50. Member 50 has a flat portion 52, which overlies thesweb of channel 40; .a downwardly extending flange 54, Iadapted'to flatly engage one of the flanges of that '7 ilf thatflug extends beyond the cylin- 'drical surfac of the spindle, aperture 42 has a correspondchannel and limit transverse movement of the latch in one direction; and a handle portion 56, which normally projects beyond the opposite side flange of channel 40 and preferably includes a depending flange portion 57 adapted to engage that flange and limit transverse movement of the latch in the other direction. Latch member 51} is spring-mounted by means of a resilient extension 55 of its flange 54, the end of which is bent and secured at 58 to the side wall of container 12. Extension 55 is so formed as to yieldingly urge the main body of member 50 toward the right as seen in FIG. 3 into firm engagement of flange 54 with channel 4%. In that normal latch position, an edge 60 of latch 50 extends below spindle lug 46, acting as a fixed abutment for lower face 47 of the lug. Downward movement of valve assembly 20 is thereby normally limited at a definite lower limit.

Manual pressure upon latch handle 56, as indicated by the arrow 59, overcomes the force of spring 55 and deflects member 5t to the valve-releasing position indicated in dot-dash lines in FIG. 3. In that position of the latch, lug 46 is free to move downward through aperture 42, and the entire valve assembly can be removed downward through the bottom of container 12.

The peripheral surface of each valve element 30 is recessed, as indicated at 34, the degree of recessing differing among the respective valve elements. A plurality of distinct recesses is preferably provided, distributed circumferentially of the valve element. However, whether the recesses are distinct or run together to form a single groove, the recessing is confined to a sector that excludes the angular portion of the valve element directly above radial support 29 on which offset handle 28 is mounted.

The axial position of recesses, 34 on each valve element 30, as shown clearly in FIG. 2, is such that in normal position of the valve assembly the recesses of the lowermost valve element lie within valve chamber ls between valve opening 16 and delivery opening 19. Up ward movement of the valve assembly carries those re cesses up through valve opening 16 into the interior of container 12, where they become filled with the powdered material stored therein. On release of the valve assembly, it falls back to the position of FIG. 2, carrying into valve chamber 18 the material contained in the recesses. That material is then deposited at the bottom of chamber 18, as indicated at 37, where it is trapped by flange 26 and retained until the next actuation of the valve. When the valve assembly is again reciprocated upwards, the lower edge of flange 26 rises above delivery opening 19, causing the material stored on the previous cycle to be delivered downward to the hand of the operator.

With the described limitation of recesses 34 to a sector of each valve element that excludes the sector directly above handle 28, little or no powdered material is delivered by the valve onto handle support 29. The tendency for material to collect on that support is thereby eliminated or reduced to negligible proportions, improving the appearance and facilitating proper maintenance of the equipment.

The described structure provides rugged, simple and reliable means for varying the quantity of soap, or other finely divided material, delivered on each stroke of the dispenser. To adjust the delivery, valve assembly 20 is removed from the dispenser by releasing latch 50 as already described. Retainer 25 is then removed, and the valve elements are removed from spindle 22. The selected valve element is then replaced on the spindle, and the remaining valve elements are assembled above it, with formations 31, 32 in register at each mating surface. Retainer 25 is then replaced and the adjusted valve assembly is returned to operating position and secured by latch 50.

A particular advantage of the described structure is that it may provide adjustment for other variables than the delivery per cycle. For example, the several valve 4. elements may differ in diameter, providing different clearance between their periphery and the edge of valve opening 16. An appropriate unit may then be selected conveniently for each of several particle sizes of material to be dispensed.

The drawings further illustrate an improved cabinet for a dispenser of the described type, which cabinet may be installed in a wall with its front flush with the wall surface. Such a cabinet is indicated generally at 7%, with a hinged door 72. Door 72 is hinged at 74 at one side of the open front of the cabinet, and closes only the upper portion thereof. A sill 76 is fixedly mounted on the cabinet, and extends across the extreme lower part of the front of the cabinet. The lower edge 78 of the door and the upper edge 79 of sill 76 are vertically spaced from each other, forming an access opening into the interior of the cabinet. The dispenser i0 is shown mounted on the rear face of cabinet door 72, as by welding, for example, with the operating handle 28 depending below the lower edge of the door, where it is readily accessible through access opening 77.

The door is normally closed, and is provided with a lock 75, which may be released with a key for servicing the dispenser.

A tray 80 is provided to catch any soap that might otherwise be spilled onto the cabinet floor. Tray 80 is of generally rectangular shape, to fit over the floor area of the cabinet behind sill 76. The rear side wall of tray 80 preferably extends upward, as indicated at 82, and its upper edge 84 is arranged to engage the rear of dispenser 10 when the cabinet door ,is closed. The tray is thereby effectively locked in place whenever the cabinet door is locked, but may readily be lifted out of the cabinet when the door is opened for servicing. The tray side walls 85 extend obliquely from the front wall 83 to the top of rear Wall 82.

In accordance with a further aspect of the present invention, a grid-like tray cover 99 is provided, which greatly improves the appearance of the installation by hiding from the operator any spilled soap that may be lying in the bottom of the tray. Such a cover is indicated at 90, comprising a plurality of horizontally spaced vertical slats 94 which extend the entire Width of cover between supports 96. The entire cover is pivoted at the back of tray 80, as at 98, and can be lifted to the position indicated at 91 to provide convenient inspection of the tray bottom, and also to facilitate cleaning of the tray after the latter has been removed from the cabinet. In normal position of cover 99, the bottom of tray 80 is hidden from the operator, as indicated at 106); yet the thin slats 94 present no appreciable obstruction to the free deposit of spilled material in the tray.

The forward edge of cover 90 comprises an angle member 97, the depending flange of which abuts the top edge 79 of the sill. The horizontal flange of angle 97 extends rearwardly across the top of the front tray wall 83. That wall preferably extends upwardly above the top edge of sill 76, and directly supports angle member 97, thereby defining the normally horizontal position of tray cover 90. That structural arrangement is rugged and economical, prevents spilled soap from falling between the tray and sill 7 6, and prevents an attractive appearance.
