This invention relates to the dispensing of liquids charged with gas such as carbonated soft drinks.

-Heretofore difficulty has been experienced in dispensing heavily gas-charged liquids,

owing to the fact that when the charged liquid,'which is held under pressure in order to prevent the escape of the gas charge therefrom, is dispensed, it is necessarily agitated and subjected to a reduced pressure, causing it to foam excessively witha resulting loss ofa considerable portion ofthe gas charge. An object of this invention is to provide an improved 'method and apparatus for dispensing gas-charged liquids or transferring I the n-fromone container toanother at diflerentprcssures, and in accordance with .which foaming of the liquid during such dispensing or transfer may be prevented; during which loss of the gas charge may be practically entirely prevented; with which any desired degree of foaming'may be created in order to put a top on any quantity of the dispensed liquid; and which is relatively 3 simple.

A further object is to provide an improved apparatusfor dispensing gas-charged liquids which will be sufficiently simple to be manipulated by relatively unskilled attendants; with which a gas-charged liquid maybe rapidly dispensed without foaming; with which such liquid may be dispensed'with any desired degree of foaming; which has a minimum of controls; and which is durable, compact, practical, attractive in appearance, and relatively inexpensive.

Various other objects and advantages will be apparent from the following description of two embodiments of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims. I I

Fig. 15 is another sectional elcvatlon of the same, with the section taken approximatel along the line 15-15 of Fig. 11.

Re erring particularly to Figs. 1 to 9, a frame or standard 1 is supported upon a base or platform 2, and provided with upright posts 3 which support a dispensing head 4 at a distance above the base or platform 2. The dispensing head 4 is provided with c lindr'ical terminals 5 having threaded perlpheries to which the posts 3 are connected.

In the simple form of the invention shown in Figs. 1 and 2, a double dispensing device is shown, the two devices utilizing a post 3 in common instead of having separate posts for each device. The common post 3 at its upper end is provided with two lateral branches extending in opposite directions, and the side posts 3 at their upper ends are turned toward one another and toward the central post 3*. Each dispensing head 4 is mounted between the common post 3 and a side post 3. As a simple form of connection between the posts and the head 4, each post 3 and the common post 3 may have upon their branches a rotary sleeve 6 rotatably mounted and confined thereon and threaded over the cylindrical extensions 5 of the head.

The posts 3 and 3 are hollow, and at their ends are connected to the head and provided with internal sleeves 7 which may be threaded therein. Each sleeve 7 has a forwardly projecting end which may be received in a suitable recess 8 in the cylindrical extension 5, and is also provided with a peripheral annular flange 9 behind which an inwardly extending annular flange 10 of the sleeve 6 is confined. The flange 9 confines the flange 10 of the sleeve 6 against the end of the tubular shell of the post 3 in such a manner that the sleeve 6 will be freely rotatable upon the sleeve and at the same time will be limited in axial movement thereon. Thus when the sleeve 6 is threaded upon the cylindrical extension 5 of the head 4, the end of the sleeve 7 will be drawn tightly into the cylindrical extension 5 and form a tight contact therebetween. The common post 3 has two branches which are similarly connected to the heads 4 which they support in common.

Each side post 3 is provided with a conduit 11 which passes upwardly therethrough, its ends being received within and extending all the way through the sleeve and anchored therein in any suitable manner. Preferably the end of the pipe 11 passing through the sleeve 7 is upset over the projecting end of the sleeve 7 so that when the sleeve 7 is drawn tightly into the recess 8, the end of the pipe 11 will be drawn tightly against the inner end wall of the recess 8. n the common post 3 a pipe 11, similar to the pipe 11, is provided, the pipe 11 having branches 11 and 11 which pass through the two standard branches for connection to the adjacent cylindrical extensions 5 of the two heads 4.

Each head 4 is provided with a recess 12 in its under face, the recess having a flat end wall forming a seat in which one end of a shell or casing 13 is fitted preferably with an interposed gasket 14 to provide an airtight joint therebetween. Each head 4 is also provided with recesses 15 and 16 in opposite faces and upon opposite sides, the two recesses being aligned with one another and opening in opposite directions and away from one another. The inner bottom or end walls of the recesses are spaced from one another sufiiciently to permit of the provision of passage sections therein for a purpose which will be explained presently. Passages or passage sections 17 and 18 lead from the inner end or bottom wall of each recess 15, one, such as 17, passing to a recess 8 of one cylindrical extension 5 where it communicates with the branch 11 of the pipe 11, the

othersection 18 opening into the recess 12 within the area inclosed by the gasket 14. In a similar manner, passage sections 19 and 20, corresponding to 17 and 18, are provided in the head 4 leading to the inner end or bottom wall of the recess 16.

The ends of the passages 17, 18, 19 an 20 which terminate in the recesses 15 and 16 are spaced apart from one another in each recess, the'terminals of the passages 17 and 19 in such recesses being preferably arranged axially of the recesses, and the ends of the passages 18 and 20 being disposed at one side of the axis as shown in Figs. 3 and 5. The passage 20 terminates in the recess 12 at approximately its center as shown in Figs. 1 and 3, and into the open end of the passage 19, a pipe 21 is threaded. The pipe 21 extends downwardly in the casing 13 and at its lower end is provided with a mixing device, comprising a sleeve 22 which rotates freely upon the lower end of the pipe and having a plurality of paddle blades 23 which are inclined at an angle to the length of the pipe so as to resemble propeller blades.

The sleeve 22 may be rotatably confined on the lower end of the pipe 21 in any suitable manner, such as by a bolt 24 which is threaded into the lower end of the pipe, with the head of the bolt forming a shoulder against which the hub of the sleeve 22 abuts. The pipe 21 is hollow from the end that is threaded into the passage 20 to a point adjacent the mixing device. Branch outlets or orifices 25 are provided for the lower end of the conduit of the pipe 21, adjacent the mixing device, and such outlets are inclined toward the blades 23 so that when any fluid passes through the pipe 21, it will escape through the outlets and strike the blades 23. The outlets 25 are so disposed with respect to the number of blades 23 that a blade will always be within the path of a fluid jet from one of the orifices or outlets. Therefore, a fluid passing through the pipe 21 will emerge as ets and cause continuous rotation of the mixing device. The passage 19 communicates with the recess 8 in which the pipe 11 is connected.

Valve elements 26 and 27 are disposed in the recesses or sockets 15 and 16 respectively, said valve elements each having a cylindrical portion fitting against the inner or bottom end walls of the recesses and having upon the faces abutting the end wall a channel or passage for cooperation with the passage sections which open through the end wall of the recess against which it abuts. For example, the valve element 27 is provided with a channel 28 which extends from its center or axis of rotation to opposite sides of the axis, the branches thereof making an obtuse angle to one another of approximately 150, and with the apex of the. angle at the axis of rotation.

The valve element 26 similarly has a channel 29, substantially V-shaped as shown in Fig. 6, opening through the inner end face at the center of oscillation and at two spaced points therefrom, the channel sections thereof forming with one another an acute angle of approximately 45, and with the apex of the angle at the axis of rotation of the element. When either valve element is oscillated the channel in its inner end face will move into positions in which it connects the ports of the passage sections 17, 18, 19 and 20 of the head so as to establish or interrupt direct communication between the passage sections controlled by each valve element.

Referring particularly to Fig. 8, the recess 16 is closed by a cap 30 which is threaded into the recess, the cap 30 having a flange closing the outer end of the recess and provided in said flange with an aperture 31 which is coaxial with the axis of oscillation of the valve element. In such aperture 31 a shoulder portion 32 of a controlling element 33 is rotatably mounted, said controlling element extending into a recess 34 in the outer end face of the valve element 27.

The controlling element 33 and valve element 27 may be coupled for rotation in any suitable manner, but the valve element pref erably should be capable of a limited independent endWise movement. Such a coupling may be obtained, for example, by providing pins 35 upon the valve elements in such positions as to project from the bottom wall of the recess thereof and enter apertures 36 in the abutting inner or bottom end face of the controlling element 33. A screw 37 threaded through the controlling element abutsat its'in ner end against the bottom wall of the recess 34, so that'wheni ever the screw is threaded into the controlling element, it will force the valve element 27 against the bottom wall of the recess 16.

A shoulder of the controlling element 33 en-v gages with the end wall of the cap 30 so as to take up the endwise thrust created by the screw 37 In order to take up the wear 1 caused by the oscillation of the valve element in the recess, the head may have-a hardened plate 38 anchored in the recess 36 against its inner end wall and provided with ports or apertures aligned with those of the head. A similar operating and mountingmeans is provided for the other vvalve element 2G and the corresponding parts are over and embracing the non-circular peripheral portions 39, one arm being fitted over one controlling element and thus operating one valve element, such as 27, and the other arm fitting over the other controlling element and operating the other valve element. Both valve elements are,'therefore-, concomiroject tantly operated by a common controlling handle 40. p

The arms 41 may have upon their outer faces circular hubs or bosses 42 which are concentric with the axis of oscillation of the valve element when thehandle 40 is properly fitted to the controlling elements 33.

Nuts 43 (Figs. 1 and 3) threaded upon the I enter projecting ends of the controlling elements have flanges overlapping or embracing hub portions 42 of the arms 41, to prevent withdrawal of the operating handle and thus confine it to the controlling element. Thus by means of the single controlling handle 40, the valve elements may be operated toconnect the pipes 11 or 11 to the interior of the shell or casing 13, by placing the valve elements in such positions as to couple the passage sections controlled thereby. This control will be explained more in detail hereinafter.

The posts 3 and 3, at points below the lateral branches or extensions thereof which are connected to the head, are provided with lugs 44 which extend toward one another. These lugs have slots 45 vertically therethrough between their upper and lower faces and opening from the free ends thereof. An annular ring 46 is fitted against the open bottom of the shell 13, with a gasket 47 interposed between a seat of the ring and the end of the shell or casing 13 to form an airtight seal therebetween, and this ring 46 is provided'with o I ing ears 48 which fit the s ots 45 and move vertically therethrough when the ring is moved vertically, the ears being normally disposed within the slots 45 when the ring is in closed position against the bottom of the shell or casing 13.

Rods 49 are secured in the ears 48 so as to extend from the upper and lower faces thereof, the extending ends being screw threaded to receive nuts 50 which overlap with the upper faces of the ln s 44 and prevent vertical displacement o the annular ring 46. By adjusting the nuts 50, the ring 46 may be adjusted vertically and securel clamped against the bottom end of the she l 13, thus holding the shell or casing tightly against the end of the recess 12 in the under face of the head.

The annular ring 46 is provided with a depending annular flange 51 against which is fitted a bottom (:ap 52, the cap 52 having an annular channel 53 in which the flange 51 is received. A suitable gasket 54 is provided in the bottom of the channelv 53 and the flange 51 abuts against this gasket to provide an airtight seal between the cap and ring when the cap is moved into closed position at the bottom of the shell or casing. The cap 52 is provided with a depending tubular sleeve 55, rotatably received in a sleeve 56 which is fixed upon the upper end of a depending stem 57, to serve as a support and guide for the cap 52. The bottom wall of the cap abuts against the upper end of the sleeve 56 so as to be limited in its downward movement and provide a tight joint between them. A set screw 58, carried by the sleeve 56, engages in an annular groove 59 in and extending peripherally of the sleeve 55 so as to permit relative rotation of the cap and sleeve 56 and at the samev time prevent their separation from one another.

The stem 57 is tubular and extends down wardly and axially through a sleeve 60 which is carried by the bas or standard 1. The bore of the sleeve 60 is provided with bearing surfaces 61 and 62 which support the stem 57 for vertical sliding and rotary movement. The sleeve 60 is also provided with a slot 63 extending downwardly from the upper end to the bearing surface 60, and the stem 57 is provided with a projecting pin 64 which runs in the slot 63 to prevent turning of the stem until-it has been elevated approximately to a point which will carry the pin 64 above the upper end of the sleeve 60.

The upper endof the sleeve 60 is provided with an inclined cam surface 65 leading to the slot 63, and after the stem 57 has been elevated until the pin 64 reaches the lower end of the surface 65, the stem may be rotated to cause a travel of the pin 64 up the positely extend-' inclined cam surface 65. This travel of the pin 64 upon the cam surface 65 forces the stem upwardl slowly, and tightly closes the cap 52 agalnst thelower end of the shell or casing 13. The engagement of the pin 64 with the slightl inclined cam surface 65 serves also to loc the stem in its upper position until it is released by rotating 1t .to carry the pin 64 again into alignment with the slot 63.

The sleeve 56 which is fixed upon the upper end of the stem 57 has a laterall extending boss 66 which is provided with a passage 67 leading from its outer end to a vent passage 68 (Fig. 2). This passage 68 extends through the sleeve 56 and establishes communication between the interior of the stem 57 and the interior of the tubular sleeve or boss 55 of the cap 52. A handle 69 having a tongue portion 70 at one end is threaded into an enlarged outer end of the passage 67. The tongue portion 7 O has a reduced valve or pin portion 71 which extends along the passage 67 and across the passage 68. When the handle 69 is rotated in one direction to thread the tongue portion 70 further into the boss 66, the tip end portion 71 will move across the vent passage 68 and 7 close the same, and when the handle is rotated in the opposite direction about its own axis, the pin portion 71 will be withdrawn to a desired extent from the passage 68 and open it to establish communlcation between the interior of the shell 13 and the interior of the stem 57. i

The handle 69 has the double function of controlling the air vent to the casing 13 through thevent passage 68 and serving as a handle by which the stem 57 may be elevated and lowered. Thelower ends of the stem 57 and sleeve .60 are open, and a helical spring 72 supported in the lower endof the sleeve 60 extends into the stem 57 against an internal abutment thereof so as to serve as a cushion for the stem when lowered.

Referring nowoto Figs. 10 to 15, which illustrate another embodiment of the invention, the construction is generally as explained for the other figures, and correspondlng parts are designated by corresponding numerals. The head 4*, corresponding to the head 4, is provided with a bracket 73 which carries'at its upper end a small electric motor 74. The shaft 75 of the motor 7 4'extends downwardly through the head 4 and into the shell 13, and at its lower end carries paddle blades 76. The shaft terminates somewhat above the cap 52 and thus when a cup or other receptacle 77 (see Figs; 1' and 2) is disposed in the shell or casing 13, the shaft and paddle blades will enter the glass or receptacle, with the paddle blades positioned a short distance above the bottom of the cup or receptacle. Thus, when the motor is operated, the addle blades will thoroughiy' maintained airtight.

In this second emblalimcnt,fewer cont-rol-v ling positions for the handle 4-0, corre-. sponding to the handle 40 of Fig. 1, are provided for. The head 1 is constructed otherwise the same as the head 4 of the first described embodiment, except that the .passages 18 and 20", corresponding to the passages 18 and 20 of Fig. 1, discharge at one side of the center of the shell or casing 13 asshown in Figs. 11 and 15. The gas control valve 26 is constructed as in Fig. 1, but the liquid control valve element 27, corresponding gen-' erally to the element 27 of theembodiment' of Fig. 1, has only a simple channel 28? for reasons which will appear in connection with; the operation to be described. v g 7 Referring vnow'to the operation of the embodiment of. the inventionshown in Figs. 1 to 9, the device is assembled in the manner. illustrated and described. Thenone desires to draw a charged liquid, such as ginger ale,

-' to those shown in Figs. 2, 3, (Sand 7. In-

the pipe 11 is connected to a supply of the charged ginger ale under pressure and the pipe 11 is connected to a source of gas under pressure, such as compressed air or carbon dioxide. A receptacle 7 7, such as a drinking cup or glass, into which the liquid is to be drawn, is placed upon the upper face of the cap 52, it being understood that for this purpose, the stem 57 has first been lowered into the position shown at the left in Fig. 1.

The handle (39 is then grasped, the stem '57 elevated into the position shown at the right in Fig. 1 and also in the position shown in Fig. 2, until the cap 52 abuts against the lower. end of the ring 46. The handle 69 is then rotated to the left (Fig. l) to carry the pin 64 up the inclined cam surface 65, thereby wedging the cap 52 tightly against the ring 46 and effecting an airtight closure of the shell or casing 13. The handle 69 is then rotated about its own axis in a direction to close the vent passage 68 when the liquid is to be drawn without foaming or loss of any of its gas-charge. I v

The connnon valve controlling handle 4-0 is shown in normal or inactive position by the fulllines on the drawing and in the position marked A inFig. 2, and the valve elements are then in such positions that both charged liquid and gas are shut off from the shell or casing 13, and occupy the relative positions shown in Fig. 9 and designated A, these positions corresponding such normal positions of the . valve elements 26 and 27, the channels 28 and 29 in those 'valve elements will .be out of communication with both of the passagesections 18 and 20.

Where one desires to draw the charged.

liquid into the cup'or glass 77, with foammg of the, liquid, the'handle 40 is shifted rearwardly into. the position shown in dotted lines in Fig. 2 and designated B. In this sage s'ection-20, and thereupon the charged I liquid from the pipe 11 will be conducted through the passage section 19 to the-valve 6181118111327 thence through the channel 28 to the passage section 20, and thence tothe tube 21. which extends into the casing 13.

Y The liquid passing through'the' tube'21 is discharged in jets,- inclined downwardly and 1 radially, and striking the blades 23, with the result that the blades 23 will rotate and agi- 1 tate the liquid as it enters the glass or receptacle 77. When the desired amount of foaming liguid has been drawn,the handle 40 is back to the normal position (A) in shifte Fig. 2 which cuts off the entrance of the charged liquid. The handle 69 may then be rotated about its own axis to open the vent passage 68 which releases any pressure existing in the shell or casing 13. The vent pas-.

sage may, if desired, be left 0 en when foaming liquid is being drawn. T e stem 57 may be rotated to carry its pin 64 into alignment with the slot 63, and then lowered to permit \Vhen one desires to draw a quantity of the removal of the cup or receptacle 77.

charged liquid under pressure without foam-- ing, the cup or receptacle'77 is placed upon the cap 52 and inserted within the shell 13 as just explained, the vent passage 68 being closed. The valve handle 40 isv then'first shifted forwardly into the position shownin dotted lines and designated C in Fig. 2, at

which time the valve elements 26 and 27 will occupy the relative positions designated 0' in Fig. 9. During this movement of the valve ,elementswith the handle 40, they partake'iof .a counterclockwise movement as viewed in Figs. 2,-5, 6, 7 and 9.

At the end of suchv movement one arm of the channel 29 of the valve element 26'will. have communication with the passage section gas under pressure in the pipe 11 will be.

conducted through the passage section 17 to the channel 29, thence through the assagesection 18 to the interior of the s ell or casing .13. The valve handle 40 is held inthis'positi'on until the desired gaseous pressure has been created within the shell or casing 13 and within. and surrounding the cup or receptacle 77. This ressure will never exceed that of the gas wlthin the ipe 11, so that no harm will come to any 0 the parts if the handle 40 is left in this C position for too long an interval.

The handle 40 is then given a further forward and downward movement into the lowermost position shown in dotted lines in Fig. 2 and designated D. In this position of the handle 40, the valve elements 26 and 27 will occupy the relative positions shown in Fig. 9 and designated D. During such movement another arm of the channel 29 has moved into communication with the passage section 18 so that the gas under pressure is still connected to the interior of the casing 13. During the same last movement an arm of the channel 28 of the valve element 27 has moved into communication with the passage section 20, whereupon the charged liquid under pressure will flow through the pipe 11, the passage section 19, the channel 28 of valve element 27, the passage section 20 and the pipe 21 into the cup or receptacle 77.

Inasmuch as the interior of the shell or casing 13 is under pressure, even though a pressure somewhat less than the pressure upon the charged liquid entering through the pipe 11, the charged liquid will enter the receptacle or cup 77 without material loss of gas or foaming, and the gas in the cup or receptacle which is displaced by the incoming liquid will return to its source through the pipe 11", the passage section 18, the channel 29 of valve element 26, and passage section 17. Thus the pressure in the casing or shell 13 will remain constant while the charged li uid is being drawn therein. When the esired amount of the charged li uid has been drawn into the cup 77, the valve handle 40 will be moved upwardly to the normal position A, shown in full lines in Fig. 2, which effects a cutting off of both thegas and charged liquid, leaving the liquid in the receptacle or cup 77 under pressure. The handle 69 is next rotated to open the vent 68 and release the pressure in the casing 13.

Thus the charged liquid is brought to atmospheric pressure or as near thereto as desired, without agitation or foaming of the liquid and, therefore, there will be no material loss of gas. If now one desires to have some foam or top on the liquid drawn into the cup, the handle 40 may be shifted rearward'ly into the B position, at which time the charged liquid will be admitted to the cup or receptacle as before explained, and since the pressure in the cup is now that of atmos here, the entering liquid will foam and pro uce a creamy or foamy top for the liquid in the cup. The handle 40 may then be returned to the A position wherein both the compressed gas and the char ed liquid are cut off. The stem 57 may tien be lowered to carry the cup out of the casing 13, after which the cup may be withdrawn and the contents utilized.

It will be understood that if desired the liquid could be drawn into a casing corresponding to 13 directly, and then after being brought to atmospheric pressure allowed to flow into a cup or other receptacle by gravity, during which it would have little agitation tending to cause foaming and a loss of the charging gas. I

In connection with the embodiment shown in Figs. 10 to 15, the cup may be inserted in the casing 13 as described for Figs. 1 to 9. If one desires merely to mix the contents of the cup, the motor '74 may be operated, and if desired the charged liquid may be admitted by proper manipulation of the handle 40* as in the preceding embodiment. The paddle 76 will thoroughly mix and agitate the contents of the cup while the charged liquid is being admitted. Inasmuch as the shaft 75 of the mixer extends through the central part of the casing 13, the passage sections of the head are necessarily open into the casing at one side of its center.

In order to produce foam it is merely necessary to agitate the liquid, which may is unnecessary to have a separate position for the valve handle 40 in which the charged liquid is admitted without first causing gas pressure in the casing 13. Therefore, the channel 28 has a single arm, instead of' two as for the channel 29 in the embodiment of Fig. 1. A charged liquid may be drawn into a cup in the casing 13, as in the preceding embodiment. By merely shifting the handle 4L0 from the neutral position A successively to the positions C, D, the casing may be first placed under gaseous pressure, and the charged liquid then admitted while the handle is in the position D.

It will be obvious that various changes in the details, which have been herein described and illu'strated for the purpose of explaining the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
