VALVE FOR DISPENSING CARBONATED AND NON-CARBONATED BEVERAGES Frank Welty and Raymond Welty, Youngstown, Ohio, assignors to Carbonio Dispenser, Inc., Canfield, Ohio, a corporation of Ohio Application September 30, 1953, Serial No. 383,317
6 Claims. (Cl. 137-637) The present invention relates to iluid valves, and more particularly to an improved valve assembly for mixing and dispensing carbonated and non-carbonated beverages.
It is presently a common practice in taverns and soda fountains and the like to provide facilities for serving soft drinks which include valve mechanisms which are capable of properly mixing a plurality of soft drinks from components thereof and dispensing the beverages in a readyto-drink condition. Heretofore we have developed valve assemblies for this purpose which comprise a plurality of valves for dispensing a avoring syrup or extract and one or more valves for dispensing carbonated water, the valve assemblies including means to properly mix the individual components prior to the liquid being dispensed from the valve outlet. For full disclosure of such prior developments reference may be had to our co-pending applications Ser. No. 97,409, tiled June 6, 1949, now U. S. PatentvNo. 2,653,055; Ser. No. 215,205, led March 13, 1,951, now U. S. Patent No. 2,702,051; and Ser. No. 282,752, iiled April 17, 1952, now U. S. Patent No. 2,766,772.
While our prior apparatus has been concerned primarily with the mixing and dispensing from a single valve assembly of carbonated beverages of a plurality of avors, we have also found that there is a substantial commercial demand for mixing and dispensing valves of this same general nature which are adapted for dispensing both carbonated and non-carbonated beverages, the term noncarbonated, as used in this sense, being sufficiently generic to contemplate beverages having a comparatively low carbonation as well as beverages having no carbonationwhatsoever.
Accordingly, it is the primary object of our present invention to provide an improved valve assembly for mixing and dispensing a plurality of ilavored beverages wherein the valve is adapted for dispensing non-carbonated as well as carbonated beverages.
Another, and lmore specific object of this invention is the provision of a valve for mixing and dispensing carbonated and non-carbonated beverages alike which incorporates a substantial number of features of our prior valve mechanisms, and which, in fact, involves a novel modification of such prior valves, so that either type of valve may be manufactured with substantially the same machining and assembly procedures. Our prior mixing and dispensing valves, for carbonated beverages, conventionally include three valves for avoring syrup, a common valve for carbonated water, and three operating levers, each of which is arranged to operate one of the syrup valves and the carbonated water valve. The arrangement is such that when any of the levers is operated the carbonated water valve and a particular one of the syrup valves open, and a drink of the proper proportions ot' each component, properly mixed, is dispensed from the valve. By our present invention, however, we propose to modify this conventional valve so that one of the syrup valves controls the ow of a non-carbonated base liquid, and to provide a novel operating lever mechanism 2,855,958 Patented Oct. 14, 1958 ICC whereby one lever is operative to open syrup and carbonated water valves while another lever is operative to open two syrup valves, one of which syrup valves controls the ow of the non-carbonated base liquid. The arrangement is such that without substantial modication of the valve proper, exclusive of the operating lever mechanism, the assembly may be adapted for serving both carbonated and non-carbonated beverages, selectively.
A further object of the invention is the provision of a novel and effective yet highly simplified operating valve mechanism for adapting a conventional carbonated beverage mixing and dispensing valve for dispensing noncarbonated as well as carbonated beverages.
The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed specification and accompanying drawing wherein is shown a preferred embodiment of our invention.
In the drawing:

Figure 5 is, a front view of another operating lever of our valve; and
Figure 6 is a section view taken along line VI--VI of f Figure 5f non-corrosive material.
Referring now to the drawing, and initially to Figures 1 and 2 thereof, the reference numeral 10 designates a generally cylindrical body member of our valve, which may be constructed of stainless steel, for example, or other The body member 10 is provided centrally with a bore to receive a vertically movable valve plunger 11 having an enlarged head portion 12 and an enlarged lower end portion 13 which comprises the active valving element. Received in the lower end of the body 10, below the valve plunger 11 is a tapered sleeve and plug assembly 14 which communicates with the valve 11 and constitutes a restricted passageway leading therefrom. The assembly 14 is provided with a plurality of radially directed outlets 15 which discharge into an enlarged water entrapping chamber 16 formed by a, shell 17 and the lower axial end of the body 10. Communicating with the inlet of the valve 11 is a conduit 18 and passage 19, comprising an inlet source for carbonated water under high pressure. And, as is fully described in our co-pending applications, when rthe valve 11 is opened carbonated water passes through the restricted passage of the plug assembly 14, where the pressure of the water is reduced substantially to atmospheric pressure, after which the water is discharged into the enlarged entrapping chamber 16. A number of outlets 20 are provided in the shell 17, each surrounding the outlet of another valve, as will presently appear.
Slidably received in the body vmember 1,0, at the upper end thereof, is a thimble 21 which is in the form of an inverted cup and which overlies the head of the valve plunger 11. In accordance with the teachings of our prior inventions the thimble Z1 provides a large head area so that the valve 11 may be operated by any ofr a plurality of levers, as is desired in the conventional embodiment of the valve.
Positioned on lopposite sides of the valve 11 are vertically slidable valve members 22 and 23 which are emvalves. As indicated in Figure l, the valves 22 and 23 lie substantially in a common plane with the water valvef 3.. 11 `andrthis is desired kininthewconventional valve assembly so that either the valves 22 and 23, which normally control the flow of avoring syrup, may be operatedsubstantially` .simultaneously with the Wateryalve levers positionedin sidefby-side.l relation. adjacent the,

Referring now to Figure 2, it will be. observed that we provide .a third syrup. yvalve .A24 Awhich v,is positioned forwardly of the watervalve 11 in I.spacedtrelation toV the plane defined by the valves-22 Vand-23 .and waterv valvell." Valve -2:-. is similar..in substantially. all respects to valves 22 and 23.
yOver'laying the. .lastmentioned .valve 24 is a horizontally disposed bar 25, one end of which is loosely re-- ivefl infaomplementary recessv inthe thiribls.. 21-
The arrangement is such that upon-a downward moving forceA being appliedto-the bar .25'both-the thimble 21 and the bar are moved downwardly to simultaneously,y
openavalves 111 andj ,24. While .upon application of a downward force to the thimble alone, the bar 25 remains stationary, permitting valve 11 to be opened withoutgopening valve-24.
Securedto the bodyl member 10, at the upper endthreof,are spaced supporting blocks 26 which are bored vertically' to receive retaining bolts 27. The blocks -26 are-:also bored horizontally to receive-.a horizontally disposed -pivot rod 28 which is located generally directly abovethe hvalves 11, 22 and 23, as indicated in Figure 3, for example.
Itrshould be understood that the apparatus describedH in-the foregoingY ,is merelyour conventional mixing -and dispensing valve-fora plurality of car-bonated.beverages, substantially asllset forth in our heretofore mentioned co-ipendingjapplications To aid in a fullunderstanding ofgourpresent and prior inventions it should vbe noted that our conventional valve assembly we provide three operatingglevers, not shown, positioned in side-by-side relationtronv the pivot -rod 28. The center lever of the threethas a cam surface overlying the horizontally dise,
posed bar. 25 and the center portion of -the thimble 21 sol thatupon operation of the lever water-.valve 11 and syrup-valve 24 will be, openedto vdispenseV a carbonated bever age.ofa.`.desired avorf The outen-levers of the three ,eaeh have cam surfaces overlying -oneioffthe syrup valves. 22 :or 23 and an edge portionof the thimble 21 so,that upon Ioperation ofeither of these last mentioned levers carbonated-beverages. of other `desired flavors may aswell; as carbonated beverages,- the .objects Vcontemfk plating the incorporation in such modification of a body member 10, with its housed valving elements, which is substantially identical with that incorporated into our conventional valve whereby machining and assembly procedures may be standardized to a la'rge degree in the production of both types of valves.
In the mixing and dispensing of non-carbonated beverages it may be ydesired to use as a baseliquid. either fresh water or carbonated water having a veryflow carbonation in comparison with what is normally termed carbonated water. And we have found thatin eitherv instance it is unnecessary to provide for the restriction and trapping of such fresh or slightly carbonated water inasmuch as the pressures involved are substantially less and there is no problem of avoiding substantial loss of carbonation. Accordingly, we have found that such fresh or slightly carbonated water may be satisfactorily dispensed from one of the valves 22-24 which is conventionally utilized to control the flow-of avoring syrup.
Thus, in the preferred embodiment of oui-inventionA we may connect a source of fresher slightly carbonated water, not shown, to the inlet of valve 23, for example., And upon opening of such valve the watermay ow., directly into the mixing funnel 29 without first passing., through any substantial restriction or trapping chamber as is desired indispensingnregular carbonated Water.
Of course, itis contemplated that a proportionate quantity of avoring syrup. will be dispensed simultaneously withthe non-carbonated water; And for this purpose weprefer to utilize Avalve 22, which -may be connectedtova'source, not shown, of such syrup, and which,4
in accordance withf-the teachings of the invention, is
caused. toppen simultaneously or substantially simpl:- taneously with-the,` opening ofthe non-carbonated watervll valve 23.
To operate thefvalvesv 22 and 23 in thel Imannezide-l sired we have provided a novel valve voperating member;
30 which is provided with a pair of spaced butrigidly., connected operating cams 31 and 32 of the type sholxtvnv inV Figure 6. In accordance with the teachings of invention .the-,cams 31 ,and 32 Vare disposed over.tlil
exposed heads `of valves 23 and 22,'respectively,y`and arerrigidlyeonnected alongj their back edges by `an infn tegral bridging. member .33,there being formed warning- A tegral.;U -shaped assembly, `as shown in Figure. The; camsv31 and `32 are also, provided with aligned,,bores` 34y and 35 which are. arranged to receive the pivotrndr- 28 whereby the Y cams, mayjbe pivotallyl `mounted in op;t j
eratlve relation over the valves 22 and 23.
AsV shown in Figure- 3,.in the preferred embodiment of therinvention cami31 ,is Of somewhat greater thicknessthan the cam32. Andintegral with and extending. upwardly from the inner Vedge of the cam31- is4 an op? erating lever 36 which is provided with a threaded upper end portion to receive a knob'37. The. 'arrangement is such that an operator may grasp the knob 37 and draw the same forwardly so that the cams 31 and 32 depress valves `22 'andV 23. to release components for, a non-carbonated drink.` It will be understood, of course that such components are mixed in the funnel 29 `and fur-4 ther during ,gravity flow into a cup or glass heldbelow. the outlet of .the funnel .so thata uniformly mixed drink, is*l obtained.
Also4 mounted on. the. pivot rod. 28, .between .theninp tegrally connected cams 31 and 32.is a second valveopf, erating member. 38 havinga cam 39 which is similar, to the `earns 31` ankd.32,jl but which is disposed over the thimble21 and horizontallyu disposed bar` 25,V the,.ar; rangementV being such thatupon rotation of the cam 39,` thethimble 21 kand bar 25-are simultaneouslyl depressed. toppen valvesv 24vV and,11 And vin Iaccordance withthe teachings of. theinvention. the Avalve 24. controls thetlow.V of avoring syrupfwhilellthevalve 411 havingran outletf rasaseleadins; tcfthe. owvmtrictrf .14 and water trapping, chamber 16 controlsnthe flow of jcarbonated watten,M
that is, highly carbonated water, which formsa conventional component of carbonated beverages.
Integral with and extending upwardly from the cam 39, at the side thereof opposite the operating lever 31 is an operating lever 40 for the cam 39, whichlast mentioned lever is also provided with a threaded upper end portion for receiving a knob 41. As will be apparent inFigures l and 3 the operating levers 36 and40 are symmetrically disposed with respect to the valve assembly as a whole. And this is provided by making the cam 31 wider than cam 32 as will be understood.
In the embodiment of the invention herein illustrated the operating levers 36 and 40 are spaced rather widely, in order to obtain a more pleasing outward appearance, and therefore we have provided a recess 42 at 'the right hand side of the cam 39 so that the same clears the valve 22 at all times.
,Usually it is desirable to restrain the free movement of the valve operating members 30 and 38 somewhat. And for this purpose we prefer to provide an annular recess, as at 43 and 44, in each of the members 30 and 38. The recesses 43 and 44 are adapted to receive conventional O-rings, as shown at 45 in Figure 4, which frictionally grip the pivot rod 28 in the assembled apparatus to thus provide a predetermined restraining force to all movement of the operating members.
ln the illustrated embodiment of the invention we provide means to prevent or limit rearward movement of the levers 36 Vand 40 comprising lugs 47 and 48 which engage the upper surface of the body member to provide a positive stop, dening a normal or neutral position for the levers.
To enclose the mechanism at the upper end of the valve assembly we provide a cup-like cap 46 which is provided with. suitable slots 47 to receive the operating levers 36 and 40. Screws, not shown, or any other suitable means may be employed to retain the cap 46 in yassembled relation. The funnel 29 is generally secured in a like manner at the lower end of the assembly. And as will be readily observed, the cap 46 and funnel 29 serve to continue the general smooth contours of the valve assembly and to provide an overall pleasing outward appearance.
lt should now be apparent that we have 'accomplished the objects initially set forth. We have provided a novel and highly simplified modification of our conventional carbonated beverage mixing and dispensing valve whereby the same is adapted for the mixing and dispensing of a non-carbonated beverage as well as a carbonated beverage.
As has been fully explained in the foregoing specification we Ihave accomplished this modification without altering in any substantial regard the 'main body portion of the valve, including the body member proper and the active valving elements and other elements incorporated therein. Rather the modification is accomplishedv by means of a novel modification of the valve operating members whereby in place of the conventional mechanism, comprising three independent levers, eachoperative to actuate a separate syrup valve and a common carbonated water valve, we provide two levers one of which comprises spaced but rigidly interconnected cam operators which are arranged to operate two syrup valves simultaneously, and the other of which is arranged to operate a syrup and a carbonated water valve simultaneously in the conventional manner. Thus, in our present modification we may connect a source of fresh or slightly carbonated water to one of the syrup valves whereby upon actuation of one of the operating members a non-carbonated drink is mixed and dispensed.
Through our novel modification we may maintain substantially ystandardized manufacturing procedures in the commercial production of valve assemblies having widely divergent application in use, lall of which results in substantial economies as will be readily understood. And there, are further advantages accruing to the modified apparatus in that the many advantageous features of the conventional apparatus may be retained substantially throughout.
It should be understood, however, that the` embodiment herein illustrated and described in detailis intended to be illustrative only, and reference should be, h'ad to the following appended claims in determining the full scope of the invention.
