DISPENSING APPARATUS FOR DISPENSING BEVERAGES OF MIXED LIQUIDS Rudolph Yuza, Chicago, 111., assignor to A. Dalkin Company, Chicago, 111., a corporation of Illinois Application September 21, 1945, Serial No. 617,707

the'invention is theprovision for moving the syrup ejecting piston by resilient pressure, resulting from and by reason of a spring connection between the driving piston and the driven piston, with the resulting structure affording a predetermined movement of the driving piston prior to the movement of the driven piston, against a body of syrup previously drawn into a measuring chamber.

' Yet another and equally important object of the invention is the provision of a dispensing apparatus of the character hereinafter'described, wherein there is obtained a high volume of gas in the carbonated water at the dispensing area, resulting in the dispensing of a highly carbonated drink, with the minimum amount of foam.

Still a further object of the invention is the provision of an apparatus of the character hereinafter described which, by its employment, assures a rapid dispensing of a mixed drink, usually consisting of a syrup and carbonated water. It is common knowledge that delay is encountered in preparing and serving a mixed drink by reason of the fact that in the dispensing of a drink consisting of a syrup and carbonated water, a large or deep foam head results, with the consequence that the operator must wait until the foam is substantially dissipated before adding to the drink additional carbonated water and syrup to provide a mixed drink of proper volume. this in mind, it is an object of the invention to dispense the syrup and carbonated water in the drinking glass in a manner such that a relatively small foam head is formed, during the mixing operation, thereby facilitating rapid succession in the dispensing of the mixed drink.

A still further object of the invention is the provision of an apparatus having a constructure serving to liberate excess gas in the carbonated water during the mixing operation resulting in higher carbonation of the drawn drink.

Another equally important feature of my invention is the advance and after flow of carbonated water in the drawing of a drink thereby With 9 Claims. (Cl. 225-21) 1 the preferred form of construction, and in which:

allowing a deposit of water in the glass prior to the flow of carbonated water and syrup in the glass and a wash of water around the nozzle after the syrup flow has ceased.

Other objects will appear hereinafter.

The invention consists in the novel combina tion and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing Fig. 1 is an elevational view of the dispensing apparatus embodying my invention;

Fig. 2 is a sectional detail view taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a rear view of the same;

Fig. 4 is a sectional detail view taken substantially on line 44 of Fig. 1;

Fig. 8 is a rear elevational view of the piston embodied in the invention; and

Fig. 9 is a sectional detail view taken substantially on line 99 of Fig. 2. 7

Referring to thedrawings illustrating the preferred form of construction by means of which I the several objects of the invention are accomplished, a refrigerator is indicated at H), and it is within this refrigerator that a container containin the syrup and a container containing the carbonated water are arranged, said containersnot being shown in the drawings as they may be of any conventional type of construction and do not constitute any part of this present invention.

'This refrigerator It may be of any approved construction having insulated walls I l for obvious purposes. In the front wall of the refrigerator is arranged a mounting block l2 having a central opening I3. Through this opening I3 is arranged the cylinder body [4 of my improved dispensing apparatus. This cylinder body [4 at its forward end portion is provided with a collar l6. Between the cylinder body [4 and the block 12 is an insulating sleeve 18 formed preferably of rubber or the like and having a flange l9 disposed between the collar l6 and the outside wall plate 20 of the wall I I. The inner end portion 2| of the cylinder body l4 projects inwardly beyond the inner wall plate 22 of the wall ll. Disposed over this end portion of the cylinder body It is a cap 23 having an annular seat 24 formed therein in which a sealing ring is positioned and bears against the Wall plate 22. In the end portion 26 of the cylinder body l4 are threaded a pair of bolts 21 which draw the cylinder body 14 in a direction to compress the collar l6 against the flange 19 and the annular seat 24 against the sealing ring 25, thus effecting a complete seal between the cy inder body [4 and the wall I I.

The collar i6 has an internal recess 28 into which seats the inner portion 29 of a head plate 30 formed as an integral part of a nozzle head 3|. This plate 30 provides an annular peripheral flange 32, which, when the plate is connected to the cylinder body [4 by means of screws 33, is tightly drawn up against the edge of the collar l6, as shown in Figs. 1 and 4.

The cylinder body 14 provides a substantially thick rear wall 34 having formed therein, as shown in Fig. 5; a bore 35, the inner end portion of which is reduced to provide an orifice 36 communicating with a measuring chamber 31, hereinafter more fully described. V

In this bore is threaded anipple 38. Carried by the inner ,endoi this nipple 38, as at 39, is a check valve 48 .of a well-known and approved construction. To this nipple is adapted to be connected a supply conduit (not shown) leading from a syrup container (not shown) for the admission of syrupthroughthe nipple and orifice into. the measuring. chamber .31. The arrangement is such that the syrup is permitted by the check valve ,to be drawn into the. measuring chamber 3], but when the syrup is ejected from the measuring chamber through an outlet bore, the ch'ecl valve will automatically close because of its resilient structure, andiprevent flow of the syrup from the measuring chamber 31 back into the container.

In this end wall 34, there is formed a bore 41, andjm'ounted in this bore 4l is a nipple 42 carrying, as in the case of the nipple 38, a check valve 43. This nipple 42 communicates with a vertical bore 44 formed preferably though not necessarily by a drilling into the wall 34, with a plug 45 closing the bore 44 at its upper end portion. This bore '44 communicates With a horizontal delivery passage '46 formed in the side wall of the cylinder. body 14, also preferably though n'ot'necessarily by a suitable drilling operation.

' The arrangemeneis such that the measured syrup may be forced into the bore 44 through check valve 43, but cannot be drawn back into the measuring chamber by reason of the closing of check valve 43 in a manner well kn'own in the art.

' The means for drawing the syrup into the measuring chamber 31 and for jcti'lig the measured syrup therefrom, will now be explained.

In the cylinder body I4 isarra'nge'd a piston assembly P consisting of outer piston 47. This piston 41 at its rear end portion and immensely adjacent its forward end portion, is provided with annular flanges 48 which have slidable engageinent with the inner walls of the cylinder body 14 and are provided with a number of openings 49 to permit the escape of "air so as toj all ow freedom of movement. of the piston assembly in the cylinder body I4. Embracing the outer-piston 41 "and having rolling engagement with the inner wa isnr the cylinder body it, is a resilient piston ring 51 or a construction and "form similar to hat showa nonitea" States Letters Patent No.

2311034, dated April '20, 11943, fdr providing an 4 effective seal between the outer piston 41 and the cylinder body 14.

In the lower end portion of the collar I6 is provided an opening 52 which communicates with the interior of the head 3i and with the space 58 between the cylinder body l4 and outer piston 41 for the dual purpose of permitting the exit of air from within the head 3! and the space to permit the freedom of movement of the piston 41 by means hereinafter described and for the additional purpose of allowing exit through the weep hole 52 of any condensation which might form in the head 3| or in the space 50.

The outer piston 41 has a cap 53' threaded thereon constituting the front wall of the piston 41, and this front wall is provided with an openiiig 53. Arranged within the outer piston 41 is an inner piston 54 having its side walls partially relieved as at 55 from the inner walls of the piston 4! to facilitate by reduction of friction the movement of the inner piston by means hereinafter set forth. This inne piston 54provides a mounting stud 56 in line with a mounting stud 5! formed on the rear wal1 58 of the piston 41. In the stud 56 is an escape opening 56' which allows for the escape of air from within the piston assembly the inner piston is movedrelatively to the outer piston.

Embracing the outer end portions of these mounting studs 56 and 5l', is an expansion spring 59 arranged within an expansion spring 68 having its end portions mounted upon the base portion of the mounting studs 56 and 51. The arrangement is such that the inner piston 54 will 57 against a body of syrup previously drawn into the measuring chamberBL The piston assembly P together with the walls or the cylinder body I4, provide the measuring chamber 31, Rear ward movement of this piston assembly is limited by a pilot stud '61, the length of which may be varied according to. the distance of movement of the piston assembly inthe cylinder body [4 in a direction toward the rear Wall 34.

Provided by the piston 5 and projecting through the opening 53, is a bifurcated lug 52 carrying a pintle 83 projecting through an elongated slot 84 of a connecting link 55.

This connecting link 65 has its end portion 68 pivotally connected by means of a pintle 61 to a bifurcated lug 68 formed as an integral part of a ball-shaped element 69 arranged for rotation in the slotted end portion 10 of th head 3] upon a pivot pin '12 carried by the head 3| as Shown in Figs. and 4. To this pivot pin 12 isalso connected th end portion 12 of an operating handle 74. The ball-shaped element 69 has a cam face adapted to engage the top edge 16 of a pair of spaced projections 11 formed as an integral part of a valve operating disc 18. In this head 31 there is provided a distributing chamber 19 in which is "seated a resilient "ring preferably formed of compressible material such as rubber or the like, and this valve operating disc 18 rests upon this ring 80 asshown in Fig. 4. The distributing chamber 19 has a connecting orifice '8! into which the stem 82 of the disc 18 projects. This orifice 8'l communicates with a valve chamber 83 provided at the base of an exterior bore 84 formed in the neck portion 85 of the head 3]. Threaded t me the lower end portion of this eitrior bore 84 is "a sleeve 86 formed as an integral partof a nozzle tip 81; This nozzle tip 8'1 is provided with a bore 89 into which there is slidably mounted the stud shaft 89 formed as an integral part of a valve cup 90 supporting a valve disc 9!, which, when in the position shown in Fig. 4, closes communication between the orifice 8| and the valve chamber 83.

This valve disc 9| is normally held in valveclosing position through the medium of an expansion spring 92 mounted in the nozzle tip as shown in Fig. 4; The nozzle tip 81 provides an enlarged portion 93 having slidably arranged thereon a valve sleeve 81' having a valve head 94 controlling outlet of syrup-from a syrup well 93 formed in the valve sleeve 81'. Communicating with this well 93 is an outlet 91 havin communication through a combined sealing ring and restricting duct 98, with the delivery passage 46. The ring 98 includes a rubber sleeve 99 embracing a short metal duct 99' and compressed against an adjacent wall of the body M to pre vent leakage of the syrup from the passage 46.

Threaded upon the reduced end portion of the valve head is a nozzle cap 96 providing together with the valve sleeve 81' an outlet orifice 95 for the mixed drink into the drinking glass (not shown).

7 At predetermined points radially with respect to each other, there are formed in the neck 85 vertical openings [90. Positioned in theseopenin'gs 190 are control pins NH the upper ends of which, as shown in Fig. 4 are disposed below and in slightly spaced relation with respect to the valve disc 18 and are adapted to be engaged 'by this disc 18 to bear thetapered end portions I02 against the valve sleeve 8'! to move the sleeve 8'! against the action of the spring I93 whereby to open the syrup outlet 91. While I have shown three of these controlpins NH, itismanifest that there may be less or more in number of the same.

Communicating with the bore i9 is a passage I94, and this passage in turn through a sealing ring I95, similar to the sealing ring 98,. has communication with a passage I96 formed in the cylinder body Hi and communicating with a nipple l! (Fig. to which is attached the conduit leading from the carbonated water tank.

As shown in Fig. 9, there is formed in the upper periphery of the cap 96 one or more openings I08, and communicating with these openings are vertical slots I99 to liberate for reasons hereinbefore set forth, excess gas in the carbonated water during drawing of the drink and its pase sage through the outlet orifice.

To expedite and facilitate locating the valve head 3| in its proper position with respect to the cylinder body l4 and with the handle 14 and the nozzle 38 in a substantially vertical plane, I provide, as shown in Figs. 2, 3 and i, on the cabinet 23 a locating finger 2!. This locating finger 21" for the purpose of locating the valve aforesaid, cooperates with a U-shaped projection 22 carried by the inside wall plate 22 of the wall structure H.

The flow of the syrup, under ejection from the measuring chamber, is through the nipple 42, the check valve 43, the port 44 and into the outlet passage 46, through the restricted duct 93 into the outlet ports 91, from whence it flows from the syrup well 93 with the carbonated water over the valve sleeve Bl" into the drinking cup or container.

- The flow of the carbonated water from a container (not shown)- is through the nipple I97, the

passage I96, the restricted duct I95, passage I04;

into the distributing chamber .19 for passage through the outlet 95, through which outlet the syrup and carbonated water will by capillary ac- 5 tionhug the valve sleeve 81 as the mixture flows into the drinking glass.

The diameter of the duct 98 in its comparison with the diameter of the restricted duct 195 is' such that the flow of syrup will be commensurate with the flow of the carbonated water to produce a drink of proper and desirable proportion of the mixture as is conducive to a well mixed drink;

In the dispensing of a mixed drink, it is desirable to draw into the drinking glass prior to the dispensing of the carbonated water and syrup a small amount of carbonated water only. This will prevent the syrup from sticking and con gealing upon the inside bottom of the drinking glass. v i

To accomplish this feature of my invention, the slot and pin connection 63 and 6%, respectively, between the handle 14 and the piston assembly 97, has been provided. The resulting structure, while opening communication between'the outlet port's i H! and the distributing chamber I9 for the discharge of carbonated water, imparts no pivotal movement to the piston assembly upon initial pivotal movement of the handle I4 about the pintle l2 toward its forwardmost position.

To condition the apparatus for the drawing of a'drink, it is necessary to draw a portion of the syrup into the measuring chamber 31. is accomplished by pivoting the handle "M about its pintle E2 to its extreme forward position, in which position of the handle 14, the piston assembly 41 will be disposed in its innermost position within the cylinder body Hi. Thehandle H3 is then pivoted about its pintle l2 to its innermost position or to the position shown in Fig. 4, and duringthis pivotal movement of the handle [9, the piston assembly 5! will be moved to its forwardmost position within the cylinder body M, at which time syrup will be drawn into the measuring chamber 3?, through the check valve :83. During this conditioning of the apparatus,

only carbonated water will be dispensed through the nozzle assembly. g

With the apparatus thus conditioned, a mixed drink may be drawn, and this is accomplished as follows: The initial movement of the handle 14 about its pintle 12 in a direction toward its forwardmost position, will open the valve disc 18 to allow the flow of carbonated water through the outlet 95 into the. drinking glass so as to screen the inside bottom of the drinking glass from the syrup when the syrup and additional carbonated water are dispensed into the glass. Further movement of the handle 14 about its pintle i2 in the above stated direction, will impart movement to the inner piston 54, and this movement will continue until the springs 59 and 60 are compressed to a degree such as will move the outer piston 58 in a direction against the body of syrup previously drawn in the measuring chamber 3'5. This movement of the piston assembly 4! will force the syrup from the measuring chamber 31 through the check valve 43, into the port 44, passage 45, and restricted'passage 98, into the ports 91, and thence through the outlet 95. During this dispensing of the syrup from the measuring chamber 31, the valve disc 18 isretained open, by engagement between the cam surface 15 and the lugs T1, so that carbonated water will flow through the diverging out This let passages H into the outlet 95 where it will comingle with the syrup and flow therewith into the drinking glass.

From a reading of the foregoing description, it will become apparent that in the dispensing of the mixed drink by the use of an apparatus constructed in accordance with the disclosure herein, there is a flow of carbonated. water before, as well as after, the dispensing of the syrup with the water. This feature of the invention accomplishes the dual function of, first, providing a sufficient amount of carbonated water in the drinking glass to screen the inside bottom thereof from the syrup, reducing to a minimum the formation of a film of syrup thereon, and, second, that of washing any remaining syrup from the nozzle to avoid the presence of a film of syrup thereon which would otherwise attract insects or the like.

As a result of the foregoing construction, a measured mixed drink is drawn by the use of my improved dispensing apparatus, in, which there is present high carbonation, with the minimum amount of foam and the maximum volume of water, and that the apparatus thus described reduces to a minimum the time required to draw and serve successive mixed drinks.

From the foregoing description, it is apparent that I have provided an apparatus which is capable of the performance of all of the hereinbefore stated objects and that the same is designed with the viewpoint of economy in manufacture and efficiency in use.

While I have illustrated and described the preferred form of construction 'for oarrying my invention into effect, this is capable of variation.

and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself. of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent isr" l.
