Appnmiqn october 19, 1944, semi No. 559,344

This invention relates to a novel construction of means for dispensing a beverage; and the invention has reference, more particularly, `to means adapted to mix and dispense a beverage comprising liquid ingredients simultaneously drawn from independent supply sources.

'I'he invention has for an object to provide a novel means for mixing and dispensing a beverage formed by a plurality of liquid ingredients said means comprising a faucet having a plurality of liquid intake means adapted to be respectively connected to independent sources of dierent liquid ingredients which, when mixed together, produce a beverage; said faucet having manipulat-I able control valve means common to said liquid intake means; the form and arrangement of the common control valve means relative to the faucet chamber and its discharge spout being such that the plurality of liquids are simultaneously drawn from their respective supply sources, are intermingled within the faucet chamber, and the resultant beverage composed thereof thereupon discharged through the faucet spout.

Another object of the invention is toY provide a faucet for dispensing a mixture of two liquid components, one of which is gas-charged or under pressure, such, e. g., as carbonated water, and the other ofv which is a ilavoring liquid or syrup required to be supplied in minor volume relative to a major volume of the first mentioned liquid, wherein the relation of the intake of the pressure liquid to that of the ilavoring liquid, and the form and relation of the common intake control valve means to the faucet chamber and faucetdischarge spout is such that the out-ow of the pressure liquid is utilized to facilitate induction and controlled simultaneous out-flow of flavoring liquid, thus avoiding necessity for prior bulk measurement of the latter liquid.

Another object of the invention is to provide a faucet adapted to mix and dispense'two liquids, one of which is gas-charged or under pressure, wherein means is provided for reducing and controlling thepressure of the latter liquid prior to flow thereof into the faucet' chamber, whereby the in-ow thereof is rendered sufciently uniform to prevent abrupt or excessive changes in velocity, and whereby this liquid is kept in substantially calm liquid condition with its activating gases retained therein, and so `that the ultimately formed beverage, containing the added t claims. (ci. zes-2s) fiavoring liquid, may be dispensed from the faucet vide a means for mixing and dispensing a beverage `comprising liquids received -by a faucet. from independent or different sources, said faucet having separate intakes for each liquid, auxiliary valve means being provided for modifying ythe inflow volume of at least one of said liquids.

l Other objects of the invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Fig. 1 is a vertical longitudinal sectional view through a mixing and dispensing faucet according to this invention, showing the same in closed condition; Fig. 2 is a fragmentary view thereof in part vertical longitudinal section and in part elevation, showing the same in open condition; and Fig. 3 is a fragmentary transverse vertical sectional view, taken on line 8-3 in Fig. 2.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

The illustrative embodiment of this invention as shown in the drawings includes a faucetbody 5 having an internal chamber 6 from which leads a discharge spout 'I with which the faucet body is provided. In` its inner end portion, said faucet body 5 is provided with an enlarged valve chamber 8 which communicates with the faucet chamber 6, said valve chamber being provided with a valve seat 9 at the juncture thereof with said faucet chamber 6; said valve chamber 8 providing the faucet intake for one liquid vdesired to be delivered into the faucet. In its outer end portion, said faucet body 5 is provided with an outwardly closed slideway I 0 which is inwardly open toward the faucet chamber 6. Mounted to slidably reciprocate in said slidewayI Il is a valve piece II, the inner end portion of which extends into the faucet chamber 6. Extending axially from the inner, end of said valve piece II and into the valve chamber 8 is a stem I2 of reduced diameter, to the free end portion of whichis suita- .bly ailixed a valve head I3 for cooperation with the valve seat 9. Provided in the wall of the faucet body 5 is an intake port Iliwhich constitutes the faucet intake `for a'second liquiddesired to be delivered into the faucet. Provided in the valve piece II is a diametrically disposed valve port I5 for cooperationwith said intake port I4.

The valve piece II, with its described associated parts, is adapted to be axially reciprocated by an external hand lever I8 which is pivotally mounted by suitable Ymeans on and in connection with the outer end portion of the faucet body. Said vhand leverfis provided at its inner` l end with an inner lev'erlarm VI1 which engages in i a slot I8'withl which tlleouter end portion of the valve piece II lis provided, whereby movements of the hand lever produce operative movements of the valve piece and its associated parts.

Additionally provided in the wall of the faucet body isan air inlet passage I9, andprovided in the valve piece II is a diametrically disposed vacuum breaker port 20 which cooperates-with said air inlet passage.

The underside of the inner end portion of the valvepiece II is transversely cut away to provide a substantially flat wall surface 2| which terminates in an inclined end portion 22 `which merges with the underside contour of thevalve 1 prevent agitation and sudden expansion of the piece. The passage of the faucet spout 1 inclines downwardly and outwardly from its point of com- 1 munication with the faucet chamber 6, and consequentlytheinternal surface of the spout bot-v tom' wall diverses fromjth'e flat wall surface 2i` i ofthe valve piece II, whereby a. Venturi-likef lintermediate passage 23 is formed between the valve chamber 8 and the spout passage outlet, I

s aid Venturi-like passage beingvdisposed to unport I4. The purpose and advantage of said Ven- 1 turi-like passage will be hereinafter more fully explained. f

When the valve piece II is retracted to normal I closed position (see Fig. l), to which position it` is moved by inward swinging of the hand lever I6, the valve head I3 yseats against the valve seat 9, thus elesingihe intake ef one liquid, while at the same time the valve port I5 is withdrawn out of alignment with the intake port I4 so that y the valve piece I I also closes the intake ofthe second liquid.' When the valve piece II is thus i positioned to "close the liquid intakes, itsrvacuum breaker port is disposed in alignment with the I air inlet passage I 9, thereby opening the inte- 1 rior of the faucet chamber to communication with, the atmosphere, whereby to assure prompt and complete evacuation of liquid from the faucet chamber andvspout, and thus avoiding tendency 1 of prolonged dripping of liquid from 'the;spout. When the valve piece II is advanced to open i position (see Fig. 2.) to which position it is moved by outward swinging of the hand lever I6, the valve head I3 is removed from the valve seat 9, thus openingthe intake of one liquid, while at the same time the valve port vI5 isy advanced to laligned relation to the intake port I4I thus openjing-the intake of the second liquid. When thus advanced, l--thevalve piece II carries its vacuum 1 breaker port 23 out ofalignment'with the air i inlet'pa'ssage-IS so that the valve piece II closes ,derlie' the 'valve port I5 when the latter is'moved to opened alignment with the second liquid intake l trolled that the ultimate beverage provided by the latter .when the faucet is open `to the flow I,

\ of the liquids therethrough.

Connected with the inner end of the faucet body 5, in axially aligned relation thereto, is an exteriorly screw-threaded shank 24l adapted to be inserted through and suitably ailixed to the j wall 25 of a cabinet or other support for the faucet. Saidshank 24 and faucet body 5 are l joined together as a unitary assembly by suitable 3 coupling union means 26,- and they Joint formed by their meeting ends is sealed by an'interposed gasket 21. Provided in the faucet opposed end I of said shank 24 is a chamber 28 which forms 1 f an extension of the valve chamber 3 of the faucet body 5. Extending axiallythrough the shank 24 liquid. As a further aid in reducing the pres-Y sure of the gas-charged or pressure liquid admitted to the faucet, while at the same time de-j 'l fleeting the entering liquid for passage aroundthe v open valve head I3,.whereby to prevent, head-on collision of thedelivered liquid stream with the latter, and thus to avoid undue turbulence :of

the liquid and consequent premature release oi'.y

any activating gases contained therein, additional combined pressure reducing and dei-lector means is arranged within the chamber 28, and connected in communication with the discharge end of the shank passage 29. This'jmeans, in one illustrative form thereof as shown, comprises a liquid discharge nozzle 30 of smaller diameter than that y I of the chamber 28, the same having at its inner end an axially extending screw-threaded stemr3i adapted to be screwed into the body of the shank 24. Entering the nozzle 30 throughV said stem 3i is a passage 32 which is aligned with the shank. l l passage 29 for communication therewith, and extending radially from the inner end of said passage 32 are a plurality of lateral discharge pasl sages 33 opening out from the periphery of thev nozzle 30. When the nozzle is affixed to the shank v 24, its inner end abuts the bottom of the chamber 28, and the periphery of the nozzle is spaced concentrically to the sides of said chamber 28. thus forming Van annular vpassage 34 through which the emitted liquid flows in such manner head I3, thus preventing undue agitation and turbulence of the liquid, so that in-flow of the liquid into the faucet chamber 6 is uniformly maintained without abrupt or excessive changes of velocity, and so that substantially calm condi- As' a consequence of this, flow of the gas charged or pressureliquid through the faucet. and. itsmixture with added fiavoring liquid is so conthe mixture will discharge smoothly and quietly from the faucet spout and into a'glass without undue gas releasing agitatiomspurting or splashv 1 ing.

Suitably coupled with the faucet body 5. for

communication with the intake port I4 thereof,`is.

a second liquid deliveryconduit 35, which leads from a source of second liquid supply, such, e. g., as a supply of ilavoring liquid-or syrup'. Provided in the line of said conduit 35, and preferably chamber 6 may be suitably'lmodiiled according 7 5 36 may'be of anydesired-knowntype, and, e. g..

to-a selected proportional ratio of volume of the second liquid desired to be mixed with a given volume of the first liquid' admitted tothe faucet chamber when thefaucet lis opened-1' This valve is s liquid delivery passage ze leadingv te ysaid chamber 28. In use, the liquid delivery passage as to be deflected for passage around the valve .f

age comprising a gas-charged or pressure liquid` such, e. g., as carbonated water, and an inert or flavoring liquid, when the faucet is opened the former liquid is delivered through the shank passage 29 and nozzle 30 to flow past the unseated valve head I3 into the faucet chamber 6. and thence through the Venturi-like passage 23 beneath the valve piece Il, while the latter liquid is admitted to said Venturi-like passage 23 through the aligned intake port I4 and valve port I5. As the pressure liquid flows through the Venturi-like passage 23, its velocity is somewhat increased at the point of restriction, and as a consequence a suction effect is exerted at the outlet end-of the valve port I5 which aids induction or emission of the flavoring liquid therefrom, so that a given volume of the latter is drawn and mingles with the outgoing stream of the pressure liquid. The volume of the flavoring liquid may be proportionally predetermined relative to the volume of pressure liquid by adjusting the regulating valve 36, taking into consideration the degree of pressure to which the pressure liquid is subject. Inthis way, a desirably proportioned mixture of the two liquids may be formed within and thereupon dispensed from the faucet.

While the faucet is well adapted to mix and dispense two liquids one of which is a gas-charged or pressure liquid, it may also be advantageously utilized to mix and dispense two liquids which are both inert. In the latter case, one liquid may be delivered to the faucet chamber through the shank passage and intake controlled by the valve head I3, in which case the diameter of the shank passage may be suitably sized and the nozzle 30 omitted, so that flow of said liquid in desired volume under head pressure or otherwise impressed pressure may be attained. The other liquid is delivered through the aligned intake port I4 and valve port I5, and its flow in desired volume under head pressure or otherwise impressed pressure may be controlled by adjusting the regulating valve 36.
