Application August 4, 1952, Serial No. 302,560

11 Claims. Cl. 222-153) The present invention relates to dispensing means for use in the merchandising of bottled beverages, and is an improvement upon the invention disclosed in our copending application Serial No. 81,944, filed March 17, 1949, entitled Beverage Control System and Dispensing Means, now Patent No. 2,605,931, issued August 5, 1952.

An object of the invention is to provide an improved dispensing means attachable to a bottle to receive and subsequently to discharge a predetermined, measured quantity of the bottle contents.

Another object is to provide, in a dispensing means of the character indicated, means operative automatically to render the dispensing means totally inoperative unless and until a bottle to which the dispensing means is attached is in a dispensing position and the dispensing means is, at that time, conditioned to deliver only a predetermined, measured quantity of the bottle contents.

A further object is to provide, in a dispensing means of the character indicated, a novel valve mechanism controlling the outlet delivery.

Still another object is to provide, in a dispensing means of the character indicated, means operative automatically, upon attachment of the dispensing means in service relation on a bottle, to lock the dispensing means against detachment from the bottle until the bottle is rendered incapable of refilling.

Other and incidental objects will be apparent from the following description, taken in conjunction with the following detailed description and accompanying drawings, in which:

Viewed externally, as in Figure 1, the dispensing device appears as an irregular spheriod shell casing formed of two half-sections 10 and 10a. The edges of the halves meet in face contact over theirfull extent in a plane which intersects the longitudinal axis of the assembly. Securing means bind the halves tightly together in detachably connected engagement. The outer end of the shell is pear shaped and closed to encompass a trap chamber 12 for receiving a charge of liquid to be dispensed. A discharge spout 13 in the form of a tube open at both ends is integral with one of the shell sections and extends through the section wall in supported engagement therewith. The tube is inclined relative to the longitudinal axis of the shell and has an internal tube section 13a press fitted therein and extending well into the trap chamber.

The inner end of the shell is circular and open and is provided with an internal annular bead 14 which seats in a complemental receiving groove formed in the peripheral face of an annular mounting flange 15 integral with a bottle closure cap 16; thus securely locking the cap and shell against relative axial movement. The cap has a depending portion 17 adapted for detachable connection with a bottle neck 18 in the usual manner of closure caps.

A center section 19 is mounted within the shell between the trap chamber 12 and bottle cap 16. This section is here shown as a block rectangular in cross section axially of the shell and rigidly secured at its base to the cap 16. The cross sectional area of the block is appreciably less than that of the portion of the shell in which it is located, and three side faces of the block occupy planes parallel to itslongitiudinal axis. The fourth side. face, on the right in Figures 2 and 3, is inclined outwardly toward the shell wall from the base of the block to its outer end, thereby providing a longitudinal progression in the cross sectional area of the block. At its outer end, the body of the block 19 is laterally enlarged to provide an integral head 22 of oval form and dimension corresponding to the internal configuration of the shell at that point. The peripheral face of the head tightly engages the wall of the shell and is formed with an axially directed flange 23 that is externally grooved to seat over a complemental annular bead 24 on the interior of the shell, whereby the head and shell are locked against relative axial movement. The head constitutes a partition between the liquid trap chamber 12 and a register mounting portion of the assembly, and the oval configuration of the shell and partition prevents relative twisting of the parts.

Both the cap closure 16 and center section block 19 are bored to establish liquid flow and air passage communication between the bottle interior and the trap chamber 12. A bore 25 through the body of the block 19 substantially parallel to its inclined face opens to a registering aperture in the cap 16 and provides for flow of liquid from the bottle into the chamber 12 when the bottle is inverted. Air passage between the interior of the bottle and the chamber 12 is accomplished through an air tube 27 passed through the body of the cap and ment with the air tube, and mounts in the aperture a smashes tubular conduit 30 which projects a short distance into the chamber 12.

Normally the valve 29 is seated in retracted open position as shown in Figures 4, and 6. In this position its rear edge abuts the shell casing Wall and its forward edge is retracted clear of the liquid flow bore 25. Also,

in this position, a port 31 in the valve body registers with the air tube 27 and the conduit 30 to establish communication therebetween. When the valve is projected forwardly to closed position, as shown in Figure 2, the port 31 is shifted laterally to cut ofi communication between the air tube and conduit, and the valve body moves entirely across the bore 25 to cut off the flow of liquid from the bottle to the trap chamber and vice versa.

Operating movement of the valve 29 is effected by means of a lever 32 fulcrumed intermediate its ends on a pivot stud 33 on the center block 19 and extending laterally therefrom. The lever is formed with an outwardly directed portion coaxial with its pivot axis and which projects laterally through an aperture in the wall of the shell. At the outer end of the portion the lever is directed laterally to extend in spaced relation alongside the bottle 13 as a handle 36 offset with respect to the inner end portion of the lever housed within the shell. The terminal of this inner end portion has pivotal connection with one end of a retractile spring link 37 that is pivotally connected at its other end to a stud 38 carried by and extending laterally from the rear end portion of the valve 29. The stud 38 also is pivotally connected with one end of a forwardly directed link, not shown, operative by the slide valve 29 to register the number of drinks dispensed from the bottle.

The discharge spout 13a is controlled by a valve comprising a sleeve 59 telescoped over the inner end of the discharge spout. The sleeve has an internal diameter greater than the external diameter of the discharge spout whereby to provide a clearance space between the two. It is actuated from the slide valve 29 by means of an S-shaped lever 61 fulcrumed intermediate its ends on a pin 62 mounted transversely between two spaced parallel lugs 63 integral with the partition head 22, which projects through the partition head well into the liquid flow bore 25 in the path of movement of the forward edge of the slide valve 29. In the normal position of the parts, with the slide valve in retracted open position, the lever 61 is held by a spring 65 so that its cam end portion 64 is disposed in the path of movement of the slide valve 29 and its other end holds the discharge valve 60 closed against its seat in the end of the discharge tube. The spring 65 is mounted on the lever fulcrum pin between one of the lugs 63 and a head on the pin, and bears at its ends against the partition head and the lever.

In service, the dispensing register is attached to a bottle as described, with the air tube 27 extending well down into the bottle. With the bottle in upright position the slide valve 29 is held in open retracted position, as seen in Figures 4, 5 and 6 by the bias of a retracting spring 67 connected between the arm of the lever 32 within the shell and an attaching lug on the closure cap flange 15, as in Figure 3. In this position of the lever, its handle portion 36 is angled outwardly away from the bottle neck. When a drink is to be dispensed the bottle is inverted or tilted as shown in Figure 2, with the spout 13 in pouring position, whereupon liquid flows by gravity through the flow bore 25 into the trap chamber 12 displacing air which passes through the conduit 30, slide valve port 31, and tube 27 to the interior of the bottle. During this operation the slide valve 29 remains open and the discharge valve 60 remains closed. Also, the register actuating means is inoperative.

Liquid from the bottle continues to fill the chamber 12 until the level rises sufficiently to close oil the air conduit 30, at which point the liquid ceases to flow as no more air can enter the bottle from the chamber. The liquid also rises above the inner end of the tube 13a and.

r in the space between the discharge spout and the sleeve 59.

forward edge of the slide valve engages the cam end 64 of the S-shapcd lever 61 and rocks the lever on its fulcrum to pull the valve 60 from its seat and open the discharge spout. The sleeve 59 sets up a siphon action which empties the trap chamber contents through the discharge spout to dispense one measured drink from the bottle. Air for the siphon action is supplied above the liquid in the trap chamber through a shallow air channel 68 in the partition abutting face of the slide valve 29. This air channel opens at one end to the rear edge of the slide valve and extends longitudinally of the valve a sufficient distance to dispose its other end in registry with the partition air conduit 30 when the slide valve is in projected closed position, as seen in Figure 2. Air supplied through the channel 68 enters the shell through the handle lever aperture, and through the sight apertures 49 unless they are covered by transparent window panels.

As the slide valve moves forward under actuation from the handle lever it carries with it and operates the register actuating means. It is an important feature of our invention that the register cannot be actuated by operation of the slide valve unless and until the proper measured quantity of liquid is present in the trap chamber 12.

At the conclusion of a dispensing operation the bottle is restored to upright position and the handle is released, whereupon the handle lever spring 67 acts through the mechanism as described to return the parts to their original position. The upper face of the partition 22 is dished to a low point at the bore 25 so that complete drainage of the trap chamber is effected when the bottle is upright. If drinks are to be poured in quick succession from the same bottle, the bottle may be continued in its pouring position while the handle is released to permit reopening of the slide valve and refilling of the trap chamber.

In the normal upright position of a bottle with the dispensing register attached, the discharge control valve 60 is held firmly in closed position against its seat comprising the inner end of the tube This prevents the entry of fruit flies and other insects; it also prevents evaporation of the bottle contents and refilling or adulteration. Another feature of the invention is the high degree of accuracy obtainable with regard to the exact quantity of liquid to be delivered to the trap chamber at each filling. This is determined by the location of the air conduit 30; a deeper extension into the chamber makes the quantity delivered smaller, and a shorter extension makes the quantity larger.

Figures 4, 5 and 6 illustrate means for preventing operation of the register in the absence of a full charge of liquid in the trap chamber. In this embodiment, the register actuating means is biased into driving connection with the register in a conventional manner, so that the register is operated each time the slide valve 2? is moved into closed position. We employ a positive lock which holds the slide valve against closing at all times and in all positions of the assembly, except when the trap chamber is fully charged with a predetermined proper fixed on the lever extends laterally therefrom into the mouth of the liquid flow bore 25 in the path of closing movement of the slide valve 29, where it functions as a stop member that prevents closing of the slide valve. The lever 69 extends substantially midway across the face of the partition parallel to its major axis and is provided with a pin 72 directed laterally toward the casing wall. This pin 72 extends toward a substantially rectangular float 73 that is pivotally connected to a stud 74 carried by the partition and which rests normally in the position shown in Fig. 4 when the bottle is upright. The float has a lateral extension 73a which projects over the lever 69 and holds the lever against the face of the partition when the bottle is first tilted to dispensing position. The axis on which the float pivots is oif center so that the major area of the float falls in the direction of the pivoted end of the lever 69 when the bottle is first tilted to dispensing position and biases the float in bolding engagement against the lever in the absence of a full measure of liquid in the trap chamber.

When the assembly is tilted to dispensing position liquid is delivered to the trap chamber through the flow bore 25. As the level rises within the chamber the float 73 is buoyed to swing on its pivot against the bias of its weight, which is overcome. This movement continues until the rising liquid closes off the air conduit 30, at which point the chamber is filled with the proper amount and no more liquid can flow from the bottle. Also at this point, the float will have swung sufiiciently to permit the lever 69 to drop away from the partition far enough to remove the stop 71 from the path of travel of the slide valve 29. As soon as the stop 71 clears the slide valve it may be closed to cut off the flow bore, actuate the register, and open the dispensing outlet valve in the manner previously. described herein.

As shown in Figures 4-6, the support 74 for the float has also a pivotal connection 74:: with a hold down lever 75 of the form shown. This lever is planar and has a substantially circular hub 76 provided with a radial notch 77 to accommodate the pin 72 of the lever 69 when the latter is tilted away from the partition 22 in pouring position of the bottle. Normally, when the bot tle is in upright position, an arcuate extension 78 on the lever 75 provides a biasing weight which inclines the lever towards the partition 22 in a position to overlie the pin 72. Also, when the bottle is in upright position, the biasing weight of the free end of the lever 69 holds this lever against the partition 22 with the portion 71 projected into the mouth of the flow bore 25 in the path of travel of the slide valve 29, so that the valve cannot be moved to closed position.

When the bottle is tilted for pouring, as in the position shown in Figure 2, the lever 69 tends to fall away from the partition 22 but is restrained from such movement by the holding action of the float extension 73a which overrides the adjacent portion of the lever as best shown in Figure 4. At the same time the weight portions 78 of the lever 75 bias this lever to a position shown in dotted line in Fig. 6 in which the notch 77 is adapted to receive the pin 72 on the lever 69. Also in this position of the bottle, the float 73 swings over on its pivot so that its extension 73a is held against the lever 69. As previously stated, the slide valve 29 is normally held in open position, so that liquid from the bottle flows through the bore 25 into the trap chamber 12.

As liquid rises within the trap chamber it buoys up the float 73 which swings upwardly on its pivot to a position in which the extension 73a is moved out of holding engagement with the lever 69 and to such extent that the lever 69 is permitted to fall away from the partition 22. In this action the pin 72 on the lever 69 enters the notch 77 of the hold down lever 75, so that the lever 69 swings sufficiently away from the partition 22 to carry the stop member 71 entirely out of the path of travel of the slide valve 29.

, As previously described the level of liquid in the trap chamber 12 cannot rise above a predetermined point, and this point is not reached until the stop 71 on the lever 69 has cleared the path of travel of the slide valve 29. If the handle 36 is actuated before the stop member 71 clears the path of travel of the valve 29, the valve cannot be closed and the contents of the trap chamber 12 cannot be dispensed. When the stop member 71 is removed from the path of travel of the slide valve, the handle 36 can be fully actuated to move the lever 32 against a biasing pull of the spring 67. This movement of the lever, acting through the spring link 37, pulls the slide valve 29 entirely across the mouth of the flow bore 25 into closed position so that no more liquid can flow from the bottle into the trap chamber. When the slide valve 29 moves across the mouth of the flow bore 25 its leading edge engages against and cams upwardly the terminal portion 64 of the S-shaped lever 61. This camming action rocks the lever 61 on its pivot and opens the valve 60 so that the contents of the trap chamber 12 are dispensed through the discharge sprout 13. When the contents of the trap chamber are dispensed, the handle 36 is released whereupon the biasing action of spring 67 returns the lever to its normal position and at the same time returns the slide valve 29 to fully opened position. When the valve 29 is fully opened, spring 65 returns the terminal portion 64 of the lever 61 into its original position ,for camming engagement with the slide valve when it is again closed.

As shown in Figures 7 and 8, the spring link 37 is a coiled spring which houses axially therein in loose engagement a rigid pin 79. The pin extends over the full axial dimension of the spring 37 and bears at one end against the stud 38 on slide valve 29 and at its other end against the terminal portion of the lever 32. By this arrangement it will be apparent that when the slide valve 29 is locked against movement to closed position, by which movement the register means, not shown, is actuated, movement of handle 36 may be accomplished without damage to the mechanism as the spring 37 permits movement of the lever portion 32 to a suificient extent to prevent breakage of the parts. Of course when the lock means for the slide valve 29 is removed from the path of travel of the valve, the handle 36 may then be actuated. The spring 37 has suflicient tensile strength to serve in effect as a solid link which transmits the necessary actuating movement to the slide valve. When the handle 36 is released following delivery of the contents of the trap chamber 12, spring 67 returns the lever 32 to its normal position as shown in Figure 3, and the movement of the lever is transmitted through the pin 79 to the stud 38 whereby the slide valve is returned to its normal open position.

As shown in Figures 2 and 3 the outlet valve 60 com prises substantially a ball valve which sits upon and closes the inner end of the discharge spout tube 13a. The sleeve 59 is fixed within the trap chamber casing by means of a transverse pin 89 which extends diametrically through the tube 13a in sealed engagement therewith and which at its outer ends is rigidly secured, as by spot welding or other suitable means, to the adjacent surface of the trap chamber wall at the outer end of the sleeve. By this means the outer end of the sleeve 59 is spaced from the wall of the trap chamber and is held from the floor of the trap chamber a distance that will insure that the area is equal to the area of the space between the sleeve and the tube 13a, so that liquid may flow freely into the space between the sleeve and the tube 13a so that the trap chamber may be emptied by a siphoning action set up when the ball valve moves off its seat on the end of the tube 13a and closes against an annular seat 81 on the inner end of the sleeve 59. In the direction of the seat 81, the ball valve 60 is apertured to receive in force fitted engagement a cylindrical plug 82 having a fixed washer 83 on its inner end which provides a guide for a plunger 84 that extends axially through the valve seat 31 upon the inner end of the sleeve 59 and which has pivotal connection with the outer terminal of the S-shaped lever 61. The inner end of the plunger 84 has a fixed head 85 as an annular enlargement thereof and which provides a bearing for one end of a coiled expansion spring 86 that surrounds the plunger and which bears at its other end against the inner face of the washer 33. This arrangement provides a lost motion connection between the valve 60 and its actuator lever 61 so that damage to the mechanism is prevented and which insures adequate closing of the valve against its seat. The valve is centered by means of an annular flange 87 integral therewith and of sufficient extent to overlie the inner end of the tube 13a and also to contact the seat 81 when the valve is moved against that seat.

Our invention also includes a means for securing the dispensing register against removal from its position of attachment in the neck of the bottle after it is once installed. This means is shown in Figures 9 through 12 and comprises a threaded bolt stem 88 provided at its upper end with a head 89 suitably anchored in and through a stopper 9! that is secured to the bottom face of the base 16 of the dispensing register. The stem 88 is of sufficient length to extend axially within and through the bottle neck in spaced parallel relation with respect to the air vent tube 27, with the lower end of the stern extending well below the shoulder 91 of the bottle when the stopper 90 is fully seated. The lower threaded end of the stern carries a traveling nut 92, preferably of circular configuration, and which mounts diametrically opposed studs 93 upon which are pivoted a pair of latch members 94. Each latch member 94 is pivoted centrally between its ends on its respective pivot studs 93 and is of sufiicient length, when in horizontal position, as shown in Figure 9, to extend Well beyond the bottle neck beneath the shoulder 91. Each latch member is so balanced that it gravitates to a horizontal position following insertion through the bottle neck. In applying the lock mechanism, members 94 are tilted in substantially parallel relation with respect to the bolt stem 88 so that they pass freely through the bottle neck and fall into horizontal position after passing beneath the shoulder 91. The dispensing register is then rotated with the members 94 in contact with the bottle shoulder so that the stem 88 moves down relative to the nut 92 until the stopper 90 is securely wedged into fully seated engagement against the mouth of the bottle. The head 39 on the upper end of the stem 88 is so disposed that it prevents rotation of the stem 88 relative to the dispensing register on which it is mounted, so that the register and stem move as a unit.

Although we have illustrated and described certain details of structure and arrangement of parts which enter into this embodiment of our invention, it is to be understood that the structure disclosed is illustrative and not descriptive, and that Within the scope of the invention as claimed any modifications and changes may be made in the details and arrangement of parts herein shown.
