Geddes, Rochester. N. Y., minier to Richardson Corporation, Rochester, N. Y., a corporation of New York Application June 13, 1932,'Serial No. 616,919 1s claim. (ci. 22e-2s) This invention relates to improvements in beverage dispensers, and has for its principal object the provision of a dispensing faucet which is simple in construction, inexpensive to make, and

from which either a solid or foamy beverage may be obtained.

Another object of the invention is the provision of a faucet having a. discharge nozzle with two independently operable valve members, one of which is adapted to expand the charged liquid under pressure to reduce its pressure or ve'- locity before being mixed with the syrup so that a solid or non-creamy beverage is formed, and the other of which discharges the charged liquid into the syrup with full force to form a creamy or foamy beverage.

Still another object of the invention is the provision of a faucet for a beverage dispenser having a discharge nozzle and discharge openings for the syrup, with means for wetting or flushing the nozzle or discharge openings before the syrup flows into them and again after the flow of the syrup has been shut od.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims at the end of the speciflcation.

Fig. 17 is a similar view showing the valve member in an intermediate position, and

Fig. 18 is a detail sectional view taken substantially on line 18-18 of Fig. 16.

Referring particularly to the drawings, the invention is shown applied to a beverage dispenser of well known type, having a barrel-shaped casing 1 in the outer wall of which is mounted a faucet member 2 having passageways 3 and 4, the former of which is connected with a source of fluid under pressure in the casing, such as carbonated water, by means of a conductor 5. The passageway 4 is connected with a suitable source of syrup or other flavoring liquid in the casing 1 by means of the conductor 6.

At its front end, the faucet member has a transversely arranged portion projecting laterally therefrom in both directions so that it is substantially T-shaped in form having laterally projecting arms. Said arms are provided with openings at their outer ends in which valve members 'l and 8 are revolubly mounted. Projecting downwardly 85 from the faucet member at its front end and intermediate the ends of said arms is a nipple 9 of cylindrical form and internally threaded adjacent its lower end. Seated in this nipple is a plug or block 1l which is retained in position therein by 90 means of an internal annular flange 12 in a discharge nozzle 13 threaded in the lower end of the nipple and enlarged at its upper end to provide a mixing chamber 14 therein. The upper side of the plug may have a depression therein forming o5 a clearance for the valve member, and also to hold it in alinement while being mounted in the nipple. At its forward end, the passageway 3 is connected with a transversely arranged passageway 15 which connects it with the inner ends of 10o the valve openings at points adjacent their upper 'peripheries It also connects with a downwardly directed passageway 1,6 which, at its lower end,l connects it with a laterally directed passageway 17 to the valve openingfin the left side of the 19| faucet member. The passageway 4 at its forward end connects with a` transversely arranged passageway 18 which connects its forward end with the inner ends of the valve openings at points adjacent their lower peripheries.

The valve members 7 and 8 are operable independently of each other and the operation of the former will rst be described. The block 11 has a syrup discharge opening 21 therethrough leading from the valve opening to the discharge nozzle 13. The valve member 7 has a passageway 22 therethrough adapted to connect the passageway 18 with the discharge passageway 21 to conduct the syrup to the discharge nozzle when the valve member is in its open position, shown in Fig. 6 of the drawings. When the valve member is in the closed position, the passageway 22 occupies the position shown in Fig. 4, in which it is out of registration withthe

passageways

18 and 21. Mounted on the inner end of the valve member is a washer or gasket 23 which is fixed to the valve member to turn therewith. This washer is shown in detail in Figs. 9 and 10 and has two openings 24 and 25 therethrough, the former of which is arranged in alinement with the inner end of the passageway 22 and forms in effect a part of said passageway. The other opening 25 is arcuate in form and at one end registers with a passageway 26 in the valve member which connects it with an enlarged passageway 27 in the valve member, best shown in Figs. 7 and 8.

The flavoring syrups used in beverages usually contain more or less sweetening material which renders it more or less sticky or viscid, with the result that it has a tendency to adhere to the inner wall of its discharge opening 21 and make frequent removals of the plug 11 for cleaning necessary. It is therefore important to keep said discharge opening as free from adhering syrup as possible. To this end, means are provided for wetting or flushing said opening immediately before the syrup is discharged therein, which lessens the tendency of the syrup to adhere thereto, and again immediately after the syrup ceases to flow therethrough to wash out any adhering syrup. When the valve member 7 with its washer 23 is turned toward open position, the closed end of the opening 25 moves into registration with the passage 15 before the passageway 22 moves into registration with the discharge opening 21 in the plug 11. The carbonated water under pressure ows into the closed end of the arcuate opening 25 and out of its opposite end into the passageway 26 which conducts it to the enlarged passageway 27. The passageway 27 is zigzag in form, extending radially inwardly from the passageway 26 to the axial center of the valve and then radially at right angles thereto, to a point adjacent its periphery and then in a direction substantially parallel with the outlet branch 28 of the passageway 22. The force or forward velocity of the carbonated water or other fluid under pressure is spent or slowed up by battling in the opening 25 and expansion and further baffling in the passageway 27 until when it emerges from said passageway its forward velocity is relatively slow. When the valve member is moved toward open position, or in a counter-clockwise direction, as seen in Fig. 4, the open end of the passageway 27 passes over the discharge opening 21 and some of the carbonated water flows into said opening to flush it out, or wet its inner surface before the syrup ows through it. This position of the partsl is shown in Fig. 5 of the drawings. As the valve member is moved farther in the same direction, the arcuate opening 25 in the washer follows the open end of the passageway 15 and the open end of thev passageway 27 in the valve member moves past the discharge openingl 21 and into registration with a discharge opening or passageway 31 in the plug or block 11 for the carbonated water or Huid under pressure, which directs it downwardly through the plug into the discharge nozzle 13. At the same time, the open end of the passageway 22 moves into registration with the open upper end of the syrup discharge opening 21 to permit the syrup to ow therethrough to the discharge nozzle or its mixing chamber where it is diluted or mixed with the carbonated water from the opening 31 and discharged therefrom to a glass or other container in which it is to be served. Whenthe valve member is turned in the reverse direction to shut 01T the beverage, the reverse operation takes place, that is, the

passageways

22 and 27 move out of registration with their openings in the plug to shut oif the ow of syrup and carbonated water thereto, and the passageway 27 again moves over the open upper end of the discharge opening 21 to flush out any syrup adhering to its inner walls.

It will be noted that by the arrangement shown, the syrup discharge opening or passageway 21 is ushed or wetted before the syrup flows through it as the valve member is turned toward open position; when the valve member is turned in the reverse direction to shut oif the ow of the beverage, a stream of the carbonated water is again directed through the opening or passageway 21 to ush or rinse it out again after the ow of the syrup therethrough has been shut off. It will be noted that the carbonated water or fluid under pressure is permitted to expand when it enters the passageway 27 in the valve member to slow up its Velocity or spend its force. This is further accomplished by the baffling action resulting from the zigzag form of the passageway 27. The forward movement of the fluid is still further slowed up by the bent form of the discharge passageway 3l. By this arrangement, the forward movement of the uid may be slowed up to such an extent that it mixes with the syrup to form a solid beverage without the excessive formation of foam or cream. A finger-piece 33 may be secured in the valve member by any suitable means, such as a driving flt and projects outwardly therefrom through an elongated slot in the faucet member and provides a manually operated means for turning the valve member.

Referring now to the operation of the valve member 8 at the other side of the faucet member, this is adapted to control the discharge of the carbonated water or iluid from the same source into the syrup with full force to form a creamy or foamy beverage. The valve member 8 site the valve member 7 and in axial alinement therewith and adjacent the top of the plug ll. A passageway 35 in the valve member is arranged to connect the passageway 18 in the faucet member with a discharge opening or passageway 36 in the plug to direct the flow of the syrup when the valve is in open position from the passageway 18 to a discharge nipple 37 on the plug 1l and projecting therefrom into the chamber 14 at the upper end of the discharge nozzle 13.

By referring toFlg. 11, which shows the inner end of the valve member 8, it will be noted that it has three

openings

38 and 39 arranged in the same arc, and 40, each of which leads to a corresponding passageway in the valve member. The opening 38 leads to a passageway 41 extending laterally outward in the valve member and then downwardly at right angles where it is connected with a laterally inclined branch 42 which is restrcted or of reduced size and terminates at its end inthe periphery of the valve member. The opening 39 leads to a passageway 43 extending laterally inwardly therefrom, then downwardly at substantially right angles to itself to a point adjacent the periphery of the valve member, where it is branched, as at 44 in Fig. 11, one branch terminating in spaced

peripheral openings

45 and 46. The opening 40 leads to a passageway l47 which leads to a centrally arranged opening 48 in the rear end of the valve member in alinement with the open end of the passageway 17 in the valve member. Mounted on the inner end of the valve member is a washer or gasket 49 shown in detail in Figs. 13 and 14 and flxed thereto to turn therewith. The washer 49 has a plurality of openings 51, 52, 53, 54 and 55 respectively, corresponding to andI in alinement with the

openings

38, 39, 40, 48 and 35 in the rear end of the valve member. The openings 52 and 53 are arcuate in form for a purpose presently to appear.

Referring to Fig. 15, which shows the valve member in normal closed position, it will be noted that at this time the openings in the valve member or its washer 49, except the axially arranged opening 48, are out of alinement with corresponding openings in the faucet member at the bottom of the valve member. When the valve member is turned toward open position or in a counterclockwise direction, as seen in Figs. 15 to 17, the opening 52 in the washer moves into registration with the opening 15 in the faucet member and permits 'the carbonated water or fluid under pressure to ow into the passageway 43 in the valve member, the branched lower end of which opens into the enlarged upper end o f the funnelshaped discharge opening or passageway 36 in the block 11, into which it directs the fluid in two divergent streams to wet or flush out its inner surface. This operation continues until the elongated opening 52 moves out of registration with the opening 15, during which time the fluid is directed from side to side of the passageway 36, and is complete before the passageway 35 for the syrup registers with the opening 18 in the faucet member to permit its flow. When the opening 52 moves into registration with the opening 15, the

` elongated opening 53 in the washer moves into registration with the open upper end of a passageway 58 in the faucet member. This passageway extends downwardly through the faucet member and at its lower end is connected with the upper end of a passageway 59 in the plug 11, forming therewith a discharge passageway leading to the mixing chamber. The lower end of this passageway is branched, as shown in detail in Fig. 1.8, to form two lateral openings with a central opening between them which is threaded at its outer end for the reception of a nozzle 61 having a plurality of laterally directed openings for spraying the fluid against the inner walls of the chamber 14 and outer wall of the nipple 37 simultaneously with the downwardly andlaterally directed streams from the lateral openings to flush out the mixing chamber and discharge nozzle 13.V The fluid continues to flow through the passageway 58 while the arcuate opening in the washer registers with the opening in its upper end, and by reference to Fig. 16, which shows the valve member at the limit of its open movement, suc'n registration continues during part of the return stroke of the valve member until the Fig. 17 position is passed. Further movement of the valve member from the Fig. 17 position toward its open position shown in Fig. 16 moves the arcuate opening 52 in the washer out of registration with the opening 15 and stops the flow of thefluid through the passageway 43l until the opening 51 moves into registration with the opening 15 and directs the fluid through the passageway 41 to the passageway 36 at about the same time when the opening 55 moves into registration with the passageway 18 to permit the syrup also to flow into the passageway 36. Owing to its restricted discharge end 42, the fluid is discharged therefrom with considerable 'force into the syrup, forming therewith a creamy or foamy beverage.

When the valve member is turned from the open position of Fig. 16 toward the closed position of Fig. 15, the opening 51 moves out of registration with the opening 15 to shut off the flow of the fluid through the passageway 41, and the opening 52 again moves into registration with said openingto direct the fluid through the passageway 43 to ush out the passageway 36 after the syrup ceases to flow therethrough. Further movement of the valve member moves the opening 52 out of registration with the opening 15 to shut off the ow of fluid therefrom and simultaneously the opening 53 moves out of registration with the open upper end of the passage 58 and also shuts off the flow of fluid therethrough.

A finger-piece 62 is secured to the valve member,

8 and projects outwardly therefrom through an elongated slot in the faucet member whereby it may be operated. The open ends of the valve openings in the faucet member are closed by means of

caps

63 and 64 threaded therein and having centrally arranged threaded openings for the reception if

screws

65 and 66 having pointed inner ends for axial engagement with the outer ends of the valve members and serve to lock the caps against axial displacement and also to clamp the

washers

23 and 49 into engagement with the bottom of the valve openings.

It is desirable to regulate or adjust the relative proportions of syrup and diluent or carbonated water dispensed to produce the beverage and also to dispense them in the desiredlproportions so that a mixed colored beverage flows from the discharge nozzle as nearly as possible throughout the entire time required to flll the glass or other container in which the beverage is to be served. To this end, a screw 67 is adjustably threaded in an opening in the valve member and adjustable into the syrup passageway therethrough, to more or less restrict said passageway to vary the quantity ofv syrup delivered thereby in a given time interval.

Although only one embodiment of the invention is shown and described herein, it will be understood that this invention is intended to cover such changes or modifications as come within the spirit of the invention or scope of the following claims.
