Coulter, Jr., Deerfield, Ill., assigner to The Dole Valve Company, Morton Grove, lll., a corporation of Illinois Fited Jan. 15, 1964, Ser. No. 337,919 8 Claims. (Cl. 222-442) The present invention relates to liquid dispensers and more partiularly relates to a dispenser having means for dispensing a measured slug of liquid and having independent means for dispensing any selected volume of liquid from a storage container.

The illustrated embodiment of the instant invention comprises a liquid dispenser of a type which is suitable for placement in a refrigerator to provide a means `for dispensing a measured slug of water to an Iice tray to fill the tray with cold water when necessary. The dispenser could be mounted within the refrigerating compartment and arranged so that manual operation of an actuator would be effective to dispense a measured volume of water to an ice tray. In addition, separate discharge means are provided so that operation of a separator will unseat a valve member and discharge any given desired amount of cold iwater. A cold water supply and ice cube tray filler is thus provided in a single simple and inexpensive unit.

It is therefore a principal object of the present invention to provide an improved liquid dispenser having annually actuable means for dispensing a measured slug of liquid.

Another object of the invention resides in the provision of .a liquid dispenser having means for dispensing a measured slug of liquid and having independent manually actuable `means for discharging a selected volume of liquid.

These and other objects, advantages and features of the present invention Will bc-c-ome apparent lfrom time to time as the following specication proceeds and with reference to the .accompanying drawings, wherein:

FIGURE 1 is a vertical sectional View through a liquid dispenser constructed in accordance with the principles of the present invention;

FIGURE 2 is a partially sectioned, partially elevational View taken transversely through the dispenser unit shown in FIGURE l; and

FIGURE 3 is a fragmentary vertical sectional view taken in the same plane as that of FIGURE l but showing a modiiied version of the valving assembly.

The liquid dispenser x1t) illustrated in FIGURE l comprises generally a housing 1-1 having la base wall 12, a stepped shoulder 13 extending entirely around the interior thereof and dividing the interior of the housing 11 into radially reduced and radially enlarged portions 14 and 15, respectively, and has another stepped shoulder 16 which is form-ed entirely around the inter-ior of the housing 11 adjacent the upper lip 17 thereof.

A horizontally extending partition 13 has its periphery seated on the shoulder 13 and serves to divide the interior of the housing 11 into upper and lower chambers 19 and 20. An air tube 21 is iitted with an aperture 22 formed in the partition 18 so that the interior of the tube is communicable -with the chamber 2l) and this tube extends outwardly to a point just below the plane of the lip 1-7.

A removable cover 23 having an outturne-d ilange 24 is tted over the upper open end of the housing 11 with the iange 24 resting on the lip 17 and with the wall of the cover positioned somewhat above the upper end of the tube Z1.

A boss 25 is formed integrally wit-h and depends from the base wall y12 of the housing 11 and has an 4outlet passageway 26 formed therein which opens through a ice beveled throat 27 to the lower chamber .20. The throat 27 converges from the chamber 20 toward the outlet passageway 26.

A smaller boss 28 is formed integrally with and depends yfrom the partition 18 and serves to defiine an outlet port 29 which communicates the chambers 19 and 20 with one another. `It will be observed from an observation of FIGURES 1 and 2 that the ports 27 and 29 are formed coaaxially with one another. It will also be observed that the lip of the boss 2S is rounded as at 30.

A valve member, generally designated by the numeral 31, is positioned within the lower chamber 26 and is movable between the ports 29 and 27 to close one or the other of those ports as desired. The valve member comprises generally a resilient valve head 32 having a chamfered valve seating surface 33 and, at the opposite and upper end thereof, an annular seating surface 34.

The seating surface 33 is cooperable with the edge of the housing base lwall 12 defi-ning the port 27 to control the ow of fluid therebetween. The seating surface 34 is coopera-ble with the rounded lip 3l) `of the boss 28 to control the flow of liquid through the passageway 29. It -will be observed that the seating surfaces .34 and 33 are spaced .apart a distance somewhat less than the distance between the rounded lip 3i? and the edge of the housing base wall'l2 dening the port 27 so that when the valve member 31 is seated in port closing relation to one of the ports, the other port will be open.

In order to lend some rigidity to the main body of the valve member 31 and for other reasons which will hereafter become apparent, a stepped metallic support 35 is molded within the valve member 31 in the manner clearly illustrated in the drawings and has -an -outturned annular flange 36 protruding from the main body of the valve head 32. The youtturned annular flange 36 serves as a seat for one end of a -coiled compression spring 37 which has its opposite end seated against the under surface of the partition `18 surrounding the depending boss 28. The spring 37 serves then to bias the valve member 31 into seated relation with respect t-o the port 27.

VThe stepped supporting structure l38 extends upwardly within the valve head 32 to a point just below the annular seating surface V34 and the-n is stepped inwardly as at 38 and terminates then in a center section 39,. An ear 49 is bent upwardly from center section 39 andi has .an aperture 41 `form-ed therein which receives an eccentric portion 42 of a valve actuator 43 as is best viewed in FIGURE 2.

The valve actuator 43 comprises generally a straight rod 44 which is journaled within an aperture 45 in the side wall of the housing 11 land within a pair of upstanding ears 46 which are spaced apart on opposite sides of the port 29 and which are formed integrally with the partition 18. The eccentric portion 42 of the actuator `43 is bent away somewhat from the axis of the rod 44 between the ears 46 so that rotation of the rod 44 will act through the eccentric 42 and the cooperating tab 40 of the valve member 31 to unseat the Valve member 31 from the position shown in FIGURE l and raise it to a point where the annular surfa-ce '34 is seated on the lip '30 to shut 01T liquid flow through the port 2,9. The outer end of the rod 44 is bent at right angles to the main axis of the rod as at 47 and serves `as -a means by which the rod can be gripped and rotated to effect movement of the valve member 31.

Thus, when the assembly is in the position shown in FIGURE l, water contained within the upper chamber 19 will now into and till the lowerchamber 20 and any air previously contained therein will be vented through the vent sack or tube 21. The lower chamber 2@ is preferably designed to have a capacity equal to or somewhat less than an ice tray so that when the operator desires to lill such a tray the tray can be placed beneath the outlet 26 and the bent portion 47 of the rodA-l can then be gripped and turned to rotate the rod 43. Upon rotation of the actuator rodthe valve member 31 will be moved into engagement with the annular lip 30 and if the actuator is held in this position all of the water contained within the lower chamber 2@ will be expelled through the outlet passageway 26. When the actuator rod 43 is released the bias of spring 37 will serve to return the valve member 3l to the position shown in FIGURE l wherein the chamfered surface thereof is positioned in engagement with the edge of the basewalll of housing 11 defining the outlet port 27.

Independent liquid discharge means are also provided so that the operator can, by actuation of a separate member, draw otf any-desired amount of cold water from the lower chamber 20.

To. this-end, independent discharge means Sil are provided at one end of the housing 11. An outwardly protruding boss-51 is formed integrally with the housing 11 adjacent the lower chamber 20 and this boss has a bore 52 formed therein which opens from the bottom thereof. Radially enlarged and radially reduced apertures S3 and 54 are formed within the housing wall on opposite sides of the bore 52; the aperture S3 serving as a discharge port, and the aperture 54 serving as a guide for valve shaft $5. Valve shaft 55 extends through the aperture 54 and has a flange 56 adjacent the inner free end thereof upon which is seated the outwardly converging truste-conical resilient valve member 58. An outer washer 59 and the bulbous outer end portion 60 of shaft 55 serves to maintain the valve member 5S in its proper position on the shaft 55.

The opopsite end of the shaft 55 has a button 61 mounted thereon in the usual manner and this button is slidable within a guide wall d2. A washer 63 extends around the shaft 5S and is seated on a shoulder 64 of the boss 51 and maintains a sealing ring 65 in position about the shaft 55. Coiled compression spring 66 encircles the shaft 55 and has one end seated against the under surface of the button 61 and its opposite end seated on the Washer 63 and thereby serves to bias the shaft 55 toward the right as viewed in FIGURE l to thereby seat the frusto-conical surface 57' of the valve member 58 against the wall of the housing lll defining the port 53. Upon depression of the button 6i the poppet valve 58 will be unseated from the port 53 and water will be discharged through the bore 52.

FIGURE 3 illustrates a different embodiment of each of the valving asemblies. The valve member 7i) illustrated therein is similar in nature to the valve mem- 'ber 31, is somewhat differently congurated. A stirruplike strap 71 extends upwardly through the resilient valve head 73 and is carried on a horizontally extending portion '74 of a carrier 75 which carrier is in turn carried by the eccentric portion 7o of an eccentric actuator which might be just like that illustrated in FIGURE 2. In this arrangement the area around the eccentric actuator is somewhat easier to clean and it may be desirable from a sanitation standpoint.

The independent liquid discharge assembly shown in FIGURE 3 and identied by the numeral Si? is very similar in nature to FIGURE l but differs therefrom in that the main body thereof is not integral with the housing wall and in that the valve member carrying shaft is vertically rather than horizontally oriented In all other respects the valving arrangement is substantially videntical to that shown in FIGURE l.

It will be understood that these embodiments of the instant invention were made for illustrative purposes only and that various modications and variations may be effected without departing from the spirit and scope of the novel concepts thereof.
