1 This invention relates in general to certain new and useful improvements in beverage dispensing equipment.

It is the primary object of the present in+ vention to provide a beverage dispensing valve which is capable of being adjusted while in op+ erative condition whereby the rates of flow of carbonated water and syrup may be independently predetermined.

It is a-rurth'er object of the present invention to provide a beverage dispensing valve which is provided with reliable and easily manipulated operating means. 7

It is an additional object or the present invention to provide a beverage dispensing valve which is provided with means to prevent flavoring syrup capable or optionally dispensing a properly proportioned flavored carbonatednrink orunflavored carbonated water, as desired.

It is an additional object of the present inven- .tion to provide a valve of the type stated which is. capable ordispen'sing carbonated water without appreciable loss ofga'seous carbon dioxide, there- :by supplying a carbonated drink having an un:- lusually high degree of retained carbonation.

I. It is also an objector the present invention to provide a valve .of the type stated which can be precisely adjusted to throttle the flow of car- ;bonated water at any'desired rate within substantially broad limits.

It is likewise an object of the present invention to provide a valve of the type stated which can be readily and quickly dismantled and reassembled for replacement of washer and any other similar parts.

With the above and other objects in view, my invention resides in the novel features of form, construction, and arrangement and combination of parts presently described and pointed out in the claims.

Referring now in more .detail and by reference characters to the drawing which illustrates a preferred embodiment of the present invention, A designates an .underebar dispenser having a syrup pan I suitably fixed to the underside of a bar counter v(not shown); In the bottom wall 2 .of said syrup path I there is provided a circular syrup discharge aperture .3 and,- preferably, though not necessarily, disposed upon the upper face of the bottom wall 2 around said aperture.3 is a disk4 having an aperture coincident with the aperture, 3 and being integrally provided at uni"- rormly spaced intervals around its periphery with upstanding resilient prongs :5 for releasably re,- taining a cylindrical foraminous cap or strainer 15 having a handle 6 soldered upon its upperend wall. The-b'ottom wall 2 and disk 4, respectively, are provided with three equally spaced registering apertures I hand 1- for receiving button=headed lscrewswhich extend therethrough. and through ,an elliptical gasket 9 upon the underfaoe .of the .to extend forwardly and downwardly from the forward end of the pan 1|, projecting at its lower jor dischargeend .beyondthe plane of the forward end of the pan ,1 .as best seen in Figure 2.

Extendi g l ngthwise upwardly into the valve body l0, is a bore 12 terminating in a lateral take-oft into whichis welded a nipple M, at its external or outwardly projectin end, for disengageable connection t'o a carbonated water line (not shown). Atits-l'ower end, therbore l2.opens ereiasing'crosssectional area. Upon its lower end face, the nozzler-quill i6 is provided with anon- ;centricdeep groove i9 which isrounded at its top ahdibottoinledges, as shown in Figure 6.

amass Slidably fitted upon, and projecting downwardly from, the nozzle-quill I6, is a tubular nozzle 20 externally provided at its upper end with a diametrically enlarged collar 2| and being at its lower end internally tapered, as at 22, to a somewhat reduced inside diameter in the provision of a constricted discharge opening 23.

Loosely and shiftably mounted within the nozzle-quill I6 is a valve stem 24 provided at its upper end with a fixed washer ring or poppet 25 and an annular downwardly presented washer 26 for seated engagement against the seating face |1. At its other end, the valve stem 24 is threadedly secured in an internally threaded longitudinal bore a formed in, and extending axially through, a downwardly pointed concentric cone 21 having greaterangularity than the converging internal side walls of the nozzle 20 and being provided at its upper end with upwardly extending concentric or annular recesses 28 and 29 for complemental disposition, respectively, within the groove I9 and tapered passage ll! of the quill l6, as best seen in Figure 6.

Threaded in the lower end of said bore a, of the concentric cone 21 is a set screw 32 provided with a downwardly opening recess 33 for accommodating the end of a conventional Allen wrench. The cone 21 is finally secured to the nozzle 20 by loose fitting diametrical pins 30 so that the nozzle 20, cone 21, stem l6, and washer 26, move up and down together, and the cone 21 may shift laterally on the pins 30 in a self-centering manner so that the flow through the discharge opening 23 will be even, round and concentric. The

'entire assembly is normally held in downwardly shifted or closed position by a compression spring 3|, disposed annularly'around the quill l6 and the upper end of the nozzle 20 in endwise abutment on one end against the upper face of the collar 2| and on its other end against the lower end of the face l of the valve body Ill. By threading the set screw 32 upwardly or downwardly, the amount of threading of the bore a available for co-operation with the threading of the valve stem 24 may be controlled. This adjustment may be effected when the dispenser is in operating condition, obviating the necessity of dismantling. Through these means, the opening between the valve seat l1 and the washer 26, when in open position, may be controlled to insure the desired rate of fiow of the carbonated water, as will be presently more fully understood.

Extending lengthwise in the valve body In in spaced parallel relation to the bore I2 is a second bore 34, opening at its upper end upon the upper end face I I in registration with the syrup-drainage aperture 3. bore 34 is reduced diametrally in the provision of About midway of its length, the

vided on its under face with shallow drill-holes d for accommodating a spanner wrench or similar tool. Disposed within the lower end of the bore '34 for lengthwise shiftable, but leak-proof, movement therein and through the washers 31 is a tubular syrup-discharging spout 39 which is closed at its upper end by a transverse wall 40 centrally bored and tapped for receiving a screw 4|. Held in place upon the upper end of the enlarged disk 42 and washer 43, the latter being" disposed within the enlarged upper end of the bore 34 for seated engagement against the valve seat 36. Just below its closed end, the spout 39 is provided with a plurality of radially drilled orifices 44 through which syrup may flow for ultimate discharge from the lower or open end of the spout 39 and at its lower or discharge end the spout 39 is provided with a pair of aligned shallow vertical recesses 45. In its midportion, the spout 39 is externally threaded for receiving an internally threaded set collar 46 having a looking screw 41. The spout 39 is normally held in downwardly shifted or closed position with its associated washer 43 in seated engagement against the valve seat 36 by a compression spring 43, disposed annularly therearound and abuttingly engaged at one end against the upper face of the set collar 36, and at its other end against the lower end face l5 of the valve body II]. It should be noted in this connection that the washers 31 prevent leakage of syrup around the external surfaces of the tubular spout 39 and thereby obviate the tendency of the latter to gum up and stick as the leaking syrup thickens and crystallizes, which diificulty is commonly encountered in conventional devices of this type.

Mounted by screws 49, and fitting annularly around the lower end of the valve body I0, is a sleeve 56 having a skirt 5| projecting beyond the end of the valve body l0 and being, in its lower portion, internally diametrally decreased in the provision of a narrow shoulder 52. Adjacent its lower end, the sleeve 50 is provided with two diametrically opposite circular apertures 53 for loosely accommodating therethrougha transverse bar 54. At one end of said bar 54 there is provided an upwardly and outwardly extending handle 55 having a conventional knob 56 threaded upon its outer or free end. Projecting from the lower end of the handle 55 parallel to, and adjacent, the bar 53 is a stop pin 51 extending into an aperture 58 located in the sleeve 50 eccentrically with reference to bar 54. Mounted on the transverse bar 54 within the sleeve 50 are a pair of eccentric cams 59 retained rigidly on the bar 54 and in peripheral alignment with each other by set screws 60. Loosely seated upon the shoulder 52 of the sleeve 50 is a circular plate 6| provided with an enlarged aperture 62 and a relatively smaller aperture 63 for permitting the extension therethrough of the nozzle 20 and the spout 39 respectively. Provided midway between the apertures 53 and located immediately above the shoulder 52, is an aperture 64 through which the set screw 41 may be released so that the tubular spout 39 may be turned for syrup-flow adjustment by inserting a screw driver or similar thin bladed tool in the slot 45.

In operation, the syrup pan i may be filled with a suitable flavoring syrup such as, for example, Coca Cola syrup. The handle 55 is swung downwardly causing the cams 59 to be raised upwardly against the underface of the plate 6| driving said plate 6| upwardly off the shoulder 52. In moving upwardly, said plate 6|, by abutting against the underfaces of the collars 46 and 2|, causes the spout. 39. and nozzle 29 to shift upwardly whereby the associated washers 43 and 26 will be moved from the closed position shown in Figure 2 to the open position shown in Figure 3.

-When the valve is in open position, syrup and carbonated water will flow simultaneously into a glass or other receptacle which is held thereto below and the uniformly mixed beverage Will be wall 40 by means of the screw 4|.is a diametrally 18 thus made.
