15 Claims.

This invention relates to new and useful improvements in mixing faucets and more particularly to mixing faucets for dispensing carbonated and like beverages composed, for example, of a mixture of a suitably flavored syrup and carbonated or charged water.

One object of the present invention is to provide a mixing faucet of the stated character which embodies novel features of construction and arrangement operable to effect the mixture of a syrup and charged water in suitable proportions.

Another object of the invention is to provide a mixing faucet of the type described wherein a small volume of charged water entering the faucet under high pressure is caused to be reduced in pressure in successive stages therein so that there is discharged from the faucet a large volume of charged water at a minimum pressure with a minimum loss of carbonation.

Another object of the invention is to provide a mixing faucet of the character set forth which is operable to discharge a predetermined quantity of syrup therefrom each'time that the faucet is actuated to the on position thereof. I

A further object of the invention is toprovide a novel and improved mixing faucet having the features and characteristics set forth which is of relatively simplified, compact construction and entirely foolproof and efiicient in'operation and use.

These and other objects of the invention and the various features and details of the construction and operation thereof are hereinafter fully set forth and described with reference to the accompanying drawing, in which:

Fig. 1 is an elevational view of a mixing faucet made according to the present invention.

Fig. 2 is a sectional view taken on line 22, Fig. 1.

Fig. 3 is a sectional view taken on line 3-3, Fig. 2.

Fig. 4 is a sectional View taken on line 4-4, Fig. 3.

Fig. 5 is a sectional view taken on line 5--5, Fig. 3; and

Fig. 6 is a perspective view of one element of the mixing faucet.

Referring now more particularly to the drawing a mixing faucet made according to the present invention comprises essentially a casing structure l and nozzle structure 2. The casing l includes a hollow cylindrical wall member 3 which is closed at its upper end by a top plate 4 and its lower end by a bottom plate 5, the said wall 2 member 3 and top and bottom plates 4 and 5 being secured together in any conventional manner to provide internally thereof 'a fluid-tight chamber 6.

As best shown in Figs. 2 and 3 of the drawing, the casing top plate 4 is provided, for example, with a plurality of equally spaced openings 1 therethrou'gh. On the other hand, the casing bottom plate 5 is provided with a port or passage 8 which extends vertically therethrough and has its axis eccentrically disposed laterally with respect to the axis of the casing I. A pipe 9 of selected height may be provided to extend upwardly within the chamber 6 from the passage 8 for the purpose hereinafter described. In addition to the port 8, the bottom plate 5 also is provided with a second port or passage [0 which extends laterally inward from the side of said plate and then extends vertically downward therethrough as shown. It is to be. noted that in the illustrated embodiment of the invention the flow area through the port or passage I0 is substantially smaller than the flow area through the port or pas-sage 8.

Extending coaxially through the casing l and rotatably journalled in the top and bottom plates 4 and 5 thereof, respectively, is a spindle l l which is provided in its upper end portion with a port or passage l2 that extends axially downward a predetermined distance from the upper end face of the spindle and then radially so that it opens into the casing chamber 6 adjacent the top thereof as shown, said passage l2serving as a vent for the chamber 6.

Keyed to the spindle l l, for example by means of a pin I3, and overlying the upper surface of the top plate'4, is a valve plate M which is constructed and arranged as hereinafter described to open and close the openings 1 in said top plate 4 depending'upon the rotational position of the spindle l l. The valve plate I4 is urged against the surface of the top plate 4 by means of a spring or the like l5 which is fixed to the spindle I l as indicated at [6.

As previously stated, in addition to the casing l, the mixing faucet of the present invention comprises a nozzle structure 2. This nozzle structure 2 is mounted upon and rotationally carried by the lower end of the spindle i I at the underside of the said casing l in bearing engagement therewith. The nozzle structure 2 comprises an annular upper platell composed, for example, of hard rubber or. the like, which provides an adequate bearing surface forrota- 3 tional movement of the nozzle 2 relative to the casing I.

Underlying the plate I! is an annular main nozzle body 18 and beneath this there is an annular base member IS. The bearing plate ll, body 5 I I8 and base plate I!) are secured in the described relation upo n thelower, end of thespindle II by means i'isaidb ea i w th; is hi ee i' onto the spindle lower end as indicated at 2B. The nozzle body I8 is locked against rotation with 10 respect to the spindle II by providing inter cooperating flat portions 2| on said meiiibr'sfi. respectively, for example as show n in Fig, 5 of the drawings. Secured, forlgigailriple, bi' neans of threads 22 to the lower hd 6f mana ement: "5"

I9, is a mixing and discharge tip which may be of transparent material s o that the mixture and flow of fluids therethrough may be-visually observed.

The bottom end of the tip portion is closed and fluid passing downwardly therethrough is discharged outwardly through openings tli in the tip side wall (see Fig. 6 having a combined areafigreater than theflow' area through the jet 3 and passage I0. In addition to performing its special function hereinafter described, the jet 38 together with the previously mentioned sleeve 21 provide an effective interlock between the nozzle body 18 and bearing plate'l lTthereby securing the latter against rotationrelative to the body I8 and the spindle I i.

I he nozzle structure 2 together with the spindle I I" is adapted to be rotated relative to the casing structure i between on and off positions by means of a suitable handle 42 secured, for example, to the nozzle body member i8, and suitable stops E3 and 44 preferably are provided and disposed in the'path' of movement of the handlei iz to positivelylimit travel thereof be' 'i tweens 'aid'positions. These stops 43 and lt'mayfj be'providedat'the underside of a plate or bracket 45secured to the underside of the casing bottom plate 5 as shown.

In this connection, it'is to be noted with ref arm d to Figs. 4 and;5 of the drawings, that the passages 8 and It provided in the casing'bottofn' plate 5, and the ports 24'a'nd'29 in the nozzle" bearing plate I? are positioned circumferenti'ally" with respect to'on'e'l another so that. when the nozzle Zis in theffo'n? positionshown, the said" bearin plate ports 2 4 and 29 register'with'the1 casing passages 8 and i0: respectively, and that when the nozzle 2 is in the ,ofi. position the said be aring plate ports 24 and 29 areout of registry with said casing. passages 8 and ii] thereby preventing the flow of fluids through the nozzle 2 and outwardly of its tip 23. In addition, it is to be noted that the relationship oi;

these passages 8 and It and ports 24 and 29 preferably is such that, when the nozzle 2 is actuated to fon position by, the hand1e 42, the port 29 will establish communication with the casing passage ID justprior to the establishment of communication between the casing passage 8; and nozzle-port 24,,flfhe Valve plate M which is carried by the spindle II and overlies the casing top plate 4 is constructed and arranged Withrespect'to said spindle and easing plate so that when the spindle H and nozzle structure- 2 are in the:ofi position ofthe nozzle, the open-.

ings T in the casingtop plate l'will be open, and

in therjon position of the nozzle will be closed.

In operation'of a device made according-tothe' present invention, andlassurning that it is tobe employed to mix and dispense a carbonated beverage comprising; for example, a mixture in suitable proportions of a flavored syrup and a'car' bonated or charged water, the device may have its casing portion i secured in the manner illus trated in the bottom portion 46 of a suitable vessel which contains a supply of the desired syrup;- a' suitable fluid-tight joint 4'! being provided to prevent leakage of the'syrup outwardly between the vesseland casing structure Land a supply of carbonated or charged water under high pressure may be supplied to the'pas'sage' illin tliecasing bottom plate 5'by means of a'suit timetube' er ipe 48;; Y

W h the, 'z e, i e; TQf positildh ime the valv' plate r4 will bopen with respect tot the top plate openings 'I so that syrup from the vessel'will flow through said openings 1 into the chamber 6 thereby filling the latter. If now the nozzle 2 is actuated to the on position thereof, thevalve plate I4 will close the openings 1 in the top plate 4, and the ports 24 and 29 will be moved into registry with the bottom plate passages 8 and It, respectively, the arrangement being such that the port 29 moves into communication with the passage IEI just in advance of movement of the port 24 into communication with the passage 8.

As the port 29 moves into registry with the orifice or passage IE) a small volume of charged water supplied under high pressure by the pipe 48 enters the jet element 38 wherein it is deflected and discharged through openings 4! which have a combined area greater than the flow area through the jet 38 and passage l0 and thereby effect a first reduction in pressure of the charged water. The resulting streams of charged water are further deflected downwardly into port 30 which is of still greater area and effects another reduction in pressure of the water. From the port Sii the water is directed against the diffuser plate or disk 36 which again changes the direction of flow and causes the water to flow downwardly over the peripheral edge of said plate 36 into the larger space afforded by the annular chamber 3| thereby effecting a further reduction in pressure of the water. From the chamber 3| the water discharges outwardly through the series of ports 32 resulting in still a further reduction in pressure of the water, and finally strikes the tapered side walls of the discharge tip 23 with a minimum of deflection causing the several streams of water to be blended or combined into one low pressure stream of large volume which is discharged therefrom. By reducing the pressure of the charged water in this manner by successive stages within the faucet where it is confined, loss of carbonation or carbon dioxide gas in the charged water is reduced to a minimum as compared with the loss of carbonation which occurs when the pressure of charged water is reduced in a single stage and simultaneously discharged into the open atmosphere.

While the foregoing is taking place, syrup from the casing chamber 6 flows downwardly through the pipe 9 and passage 8 through ports 24 and 25 to the chamber 25 and thence through the spindle passage 28 to the discharge tip 23. Since the openings l are closed to prevent the flow of additional syrup into the casing chamber 6, only that amount of syrup Within said chamber above the level of the top of the pipe 9 will flow from the chamber through the nozzle structure as described, and it will be apparent that by providing pipes 9 of different height the quantity of syrup discharged from the device each time that it is opened may be predeterminedly selected as desired or required.

As previously described, the charged water is caused to be discharged from the nozzle just slightly in advance of the syrup, and this arrangement is provided to prevent any syrup from being discharged into the bottom of a glass or other receptacle held beneath the nozzle and collecting there before mixing with the charged wa ter. When the glass or receptacle is filled the nozzle is actuated to the off position thereof whereupon the discharge of charged water and syrup is stopped and the openings 1 in the casingtop plate 4 are opened to cause the syrup in the vessel to flow into and fill the casing membert.

.From the foregoing description it will be apparent that the present invention provides a novel improved mixing faucet which is constructed and arranged to effect the mixture of two fluids in suitable proportions. The invention also provides a mixing faucet of the type described wherein a small volume of charged water entering the faucet under high pressure is caused to be reduced in pressure in successive stages within said faucet so that there is discharged therefrom a large volume of charged water at a minimum pressure with a minimum loss of carbonation. In addition, the invention provides a mixing faucet of the character set forth which is operable to discharge a predetermined quantity of a fluid each time that the device is actuated to the on position thereof. Furthermore, the invention provides a mixing faucet having the features and characteristics set forth which is of relatively simplified compact construction and entirely foolproofand efficient in operation and use.

It will be observed, of course, that the mixing faucet ofthe present invention is not limited to the particular uses herein specified but may be employed generally in all cases where it is desired to effect the mixture and discharge of a plurality of fluids, and while a particular embodimentof the invention has been illustrated and described herein, the invention is not to be limited to such disclosure and changes and modifications may be made therein and thereto within the scope of the claims.
