10 Claims. 1

This invention relates to fountain dispensers *such as for dispensing mixed drinks consisting 'of syrup and charged Water.

The principal object of this invention is to provide an improved fountain dispenser for dispensing syrup and charged water which simply and efiectively cools the syrup and charged water, which efi'ectively maintains the proper ratio of syrup and charged water in the dispensed mixed drink, which may be securely mounted on substantially any sized fountain bar and syrup rail, which is simpl in construction and inexpensively manufactured, and which may readily be disassembled for cleaning purposes.

In carrying out this object of the invention the fountain dispenser preferably includes a cooling unit having a cooling chest for removably receiving a syrup container and having charged water passages formed integrally in th bottom thereof. The cooling chest may also receive ice for cooling the syrup and charged water. The cooling chest is located in an insulated shell which is provided with adjustable mounting means for mounting the same on substantially any sized fountain bar and syrup rail.

The cooling unit is provided with a dispensing valve which is connected by readily releasable connections to the syrup container and charged water passage in the cooling chest for dispensing 'mixed drinks of syrup and charged water. The Construction of the dispensing valve and releasable connections are such that they may be readily completely disassembled and the syrup container readily removed for cleaning purposes.

A flow control valve 'is preferably provided in the charged water line at the dispensing valve so that the charged water may be dispensed at substantially constant velocity. In one form of the invention, the syrup container is provided .with a float control so 'that syrup is also dis- 'pensed at a substantially constant -ve1ocity.

Thusthe proper ratio of syrup and charged Water inthe dispensed mixed drink is assured regardless of the size of the drink dispensed. In another form of the invention the syrup container is provided with a measuring device operated by the dispensing valve so that upon each operation of the dispensing valve a measured quantity of syrup is dispensed. Thus when a given sized mixed drink is dispensed the proper ratio of syrup and charged water therein is provided.

Further objects of this invention r'eside in the details of construction of the fcuntain dispense' and the cooperative -el'ationship of the component parts-thereof. V a

Referring first to Figs. 1 to 12 the fountain a shut dispenser for dispensing mixed drinks of syrup and charged water is generally designated at n. It includes a cooling unit having an outer shell consisting of an outer side wall ll and a bottom wall l2 which are secured together by screws !3 and an angle strip M. A gasket !5 forms a support for the cooling unit when it is Secured to a fountain bar !48. The upper edge of the side wall ll is provided with a anged strip se for securing in place a scaling gasket ll. The outer shell is filled with suitable insulating material !8 which operates to insulate a cooling chest formed of a single unit. The cooling chest includes a side wall and a bottom wall having a thick portion 2! and a thin portion 22 with an internal shoulder IQ therebetweeni The cooling unit may be supported on the bottom wall 12 of the shell by means of suitable legs 23; A strip 24 and screws 25 secure the sealing gasket ll to the cooling chest so that the insulation a is sealed in place between the outer shell and the cooling chest.

The cooling chest is preferably integrally cast` from a metal which may be readily cleaned and which has high heat conductivity such as aluminum. During the casting of the cooling chest a charged water tube 21 is integrally cast into the thick portion 2! of the bottom of the cooling chest. Preferably, this charged water cooling tube is made of stainless steel or the like. The charged water cooling tube is shown in detail in Figs. BA and 9 and includes a double layer spiral arrangement wherein the two layers communicate With each other by the bent section 28 at the interior of the spirals. charged water ised into the cooling tube 2'! through an extension 29 and is discharged therefrom through an extension 3& and a fitting 3l. The extension 25 is imbedded in an elongated boss 32 and the extension is imbedded in an` elongated boss 33, both of the bosses being formed on the bottom of the cooling chest. The extension 29 projects downwardly from the boss 32. The extension st bends upwardly through a boss 34 within the cooling chest and the fitting 3! communicates with the exterior of the chest a'djacent the bottom of the side wall 28.

In casting the charged water cooling tube in the bottom wall of the cooling chest the spiral layers are preferably held in place by four spacer brackets 36 having holes 31 for holding and properly spacing the spiral tube 21'. To two of these brackets there is preferably Secured a rod 21 for properly locating the spiral .layers in position during the casting operation.. The wall of the tting 31 is preferably maintained thick during casting to prevent collapsing of the fitting which might be caused by shrinkage of the aluminum casting. After the casting is completed then the fitting 31 is counterbored to the correct dimension.

The bottom wall of the cooling chest is provided with an upwardly extending boss 3@ adapted to support the syrup container and is also provided with a hole do therethrough in which may be Secured a coupling M for draining ice water from the cooling chest. When ice is placed within the cooling chest it is evident that heat will be rapidly conducted from the charged water in the cooling tube 2 1 thereby cooling the same. The side wall of the cooling chest adacent the fitting si is provided with an opening 622 therethrough adapted to receive a fitting for the purpose of dispensing syrup.

The shell H adjacent the fitting ?ai and the opening 12 has secured thereto a plate i i having a pair of openings therein for receiving a pair of sleeves and :16 to form oommunicating passages between the cooling chest and shell. The

cooling unit may be provided with a suitable removable cover 48 having a handle 49 to provide access to the interior of the cooling chest.

A dispensing valve for dispensing syrup and charged water is Secured to the exterior of the cooling unit adjacent the fitting 3! and opening 42 in the cooling chest. This dispensing valve includes a valve housing 50 secured by screws 52 to a mounting flange `51. The mounting ange 51 is in turn Secured by screws 53 to the plate M whereby the valve housing is securely mounted on thecooling unit.

The valve housing is provided with a pair of parallel bores extending longitudinally therethrough; Oneof the bores for the purpose of dispensing charged water includes a valve bore 55, a valve guide 56 and a valve seat 51 therebetween. The valve bore adjacent the seat 51 communicates through a lateral passage 58 with a tortuous passage 59 extendingdownwardly from the valve housing 5& as is illustrated in Fig. 5. The tortuous passage is formed by screwing a plug having coarse threads into a screw threaded opening wherein the threads seat loosely to provide a helical passage. A valve stem si! is slidably mounted in the valve guide 58 and carries at its interior end a valve head 62 having a valve member 6! adapted to engage the seat 51. The out-er end of the valve stem is secured to an abutment 63 having a horizontal notch 64.. A spring &35' engaging 'the abutment 63 operates to hold in place a resilient O-ring 66 about the valve stern 68 for sealing the same against leakage.

A ported member 67 locatedwithin. the valve bore has an enlargedportion 68 provided with a groove for receiving a resilient O-ring 69. The enlarged portion 68 is slidably received in the valve bore 66 and the O-ring 69 operates to seal the same against leakage. The enlarged portion GB engages against an abutment 16 in the mounting fiange 51 for maintaining the ported member 5? within the valve housing. The ported member extends. through the' sleeve 45 and into the ftting 3l. The outer end of the ported mem- I ber El' is enlarged at 'H and is provided with a groove for receiving an O-ring 12- for scaling the ported member within the fitting.

The inner end of the ported member 61 is closed by a wall 13 and is provided with lateral v holes 14. A cup shaped member 15 overlies the inner end of the ported member 61 and is slidable thereover. The inner end of the cup shaped member is provided With a restricted opening 15. The cupshaped member has an internal valving edge for coacting with the holes 14 for regulating the flow of charged water therethrough. A spring 'll urges the valve member 6! against its seat 51 and urges the cup shaped member outwardly as is illustrated in Fig. 4.

With the parts in the position shown ,in Fig. 4 the pressure of the charged water on` opposite sides of the cup shaped member is equal and the spring 'H maintains the cup shaped member in the position shown in Fig. 4. When, however, the valve stern is depressed to move the valve element si away from the valve seat 'l the pressure on the outside of the cup shaped member decreases whereupon the spring 'Hi is compressed and the cup shaped member moves inwardly. This movement is provided by the restricted opening 76 which produces a pressure drop thereacross. The valving edge of the cup shaped member cooperates with the holes for controlling the flow of charged water from the ported member to maintain a substantially con:

st'ant 'pressure drop across the ported end of 'the cup shaped member In this way charged water is regulated to substantially constant rate of flow. When the valve stem '68 is released and `the valve element' 6! is moved into engagement 'with the valve seat 51, the pressure drop across the ported end of the cup shaped member 'becomes zero and the spring '!'l returns the cup shaped member to the position illustrated in Fig. 4. Thus, when chargedwater is dispensed 'upon opening of the valve, it is dispensed at a 'substantially constant velocity.

The other parallel bore in the valve housing '58 includes a valve bore 88 anda valve guide 8!. The valve bore 88 communicates with a passage I 82 in which is Secured a short tube 83 having a thin plate 84 at its lower-end secured in place by a collar 86. Thethin plate 84 is provided with an opening 85 through which syrup is dispensed. r v

Slidably received in the valve bore 58 'is a ported member 88 having a valve seat 89 on its inner end; The ported member 88 is pro- "vided with a groove for receiving a resilient O- ring 98 for sealing the ported 'member in the valve bore. The ported member is provided with a shoulder 9! 'fitting in a recess in the mounting fian'ge 5! forsecuring the ported member within the valve bore. The ported member is provided with an enlargement 92 which is provided with a groove for receiving a resilient O-ring 93 for scaling the same within the sleeve 45. The enlarged portion 92 at its outer end is also provided with 'an enlarged opening 94. i

A valve stem 96 is slidably received in the valve guide 8! and carries at its inner end a valve head 91 having a valve member 98 adapted to engage against the valve seat 89. A spring 99 urges the valve member 98 against the valve seat 89. The outer end of the valve stem 96 is provided with a head !85. The bifurcated end !ol 'of a lever !88 engages underneath the head !85. Intermediate its ends the lever !88 is provided with a recess !93 by means of which the lever !88 is pivotally mounted on a pin !84 carried by the outer end of the valve housing 58. 'The other end ofthe lever !08 is-provided with an extension !82 which is received in the horizontal groove 84 of the other'valve element. i

A handle housing !86 is pivoted by a transverse pin !91 to the outer end of the valve housing 58 and is provided with a'n Operating handle. !88. Located within the handle housing !88 is a pin !89 which is adapted to engage the extension !82 of the lever !88. When the handle !88 is pushed inwardly the pin !89 pushes inwardly against the extension !82 of the lever !88. This causes opening of the charged water valve as heretofore explained. This :alsocauses the 'lever !88 to pull the valve stem 98 outwardly against the action :of the spring 99' so that the valve member 98 is moved away from the valve seat 89. 'This permits syrup to pass through the valve seat into the tube 83 and hence through the opening 85 in the lower end thereof. 'When the handle !88 is returned to its original position the charged water-valve is closed as heret'ofore explained and the spring 99 moves the valve member 88 against 'the valve seat 89 to shut oif the flow of syrup.

The bottom side of the valve housing 58 is provided with a circular opening for receiving a spout' The spout I!! encompasses the syrup .tube 83'and is held in place by a bayonet con- I neotion !!2. 'A resilient o-ring !!3 seals the spout in the opening.,` -When the dispensing valve 'is opened syrup flows into the center of the spout through the syrup tube 83 and charged water flows into the spout through the tortuous passage 59. The syrup and charged water are mixed within the spout as the same is dispensed. Vanes !!4 formed in the spout I!! assist in the mixing of the syrup and charged water. Thus, the dispensing valve dispenses a mixture of syrup and charged water.

Remova-bly located within the cooling chest is a syrup container !28 having a fioat chamber !2! in the bottom thereof. The fioat chamber is provided with a depression !22 which communicates with a syrup tube !23 having a fittng !24 on its outer end. The fitting !24 is provided with a groove for receiving a resilient o-ring !25 whereby the fitting may be slidably received in and 'sealed in the enlarged opening 94 in the ported member 88. The depression !22 of the fioat chamber !2! is adapted to rest on the boss 33 on the bottom wall of the cooling chest so as to support the syrup container in the cooling chest with the syrup tube !23 in communication with the ported member 88. A spring latch !21 is secured to the bottom of the fioat chamber !2! and engages the shoulder !9 on the bottom wall of the cooling chest for the purpose of firmly holding the syrup tube !24 in communicating engagement with the ported member 88. A link &28 engages the spring latch !21 and is guided at its upper end by a bracket !29 secured to the syrup container !28. A handle !38 is located on the upper end of the link !28 so that when the handle !38 is pulled the spring latch !21 is released to permit removal of the syrup container from the cooling chest. The link !28 also operates firmly to latch the spring latch member !21 against the shoulder !!9 for holding the syrup container in place. Thus, the syrup container may be readily removed from the cooling chest and may be readily supported within the cooling chest in a leak proof manner. The top of the syrup container !28' may be closed by a suitable cover !32 having a handle !33.

e A removable Wall separates the fioat chamber !22 from the remainder of the syrup container. This removable wall includes a disc !35 covered with a resilient material !35 such as rubber. The resilient material seals the fioat chamber !2! from the syrup container !28 and thereby provides a removable partition therebetween. The wall or partition is provided with a central opening I 31 and also with an upwardly extending vent tube !38. e

Located within the fioat chamber l3! is a fioat !39 having a valve element !48 cooperating with the opening !31 for regulating the flow of syrup from the syrup container !28 into the fioat chamber' !25. The fioat is guided in the fioat chamber by means of guide members 14! depending from the removable wall or partition !35.

The valve element !48' of the fioat !39 when in the upper position as illustrated in Fig. 3 closes the opening !31 to maintain a predetermined level of syrup within the fioat chamber. When the dispensing valve is opened to dispense syrup and charged water, syrup is withdrawn from the fioat chamber. When this occurs the fioat !39 moves downwardly to permit additional syrup 'to enter the fioat chamber from the syrup container and this will continue until the level of the syrup in'the fioat chamber z restored to the original value. Thus, the fioat !39 operates'to maintain a substantially constant head or level of syrup within the fioat chamber. In this "way when syrup isodispense d through the dlspensing valve itis dispensed: at substantially a constant velocity since the head of the syrup remains substantially constant. Hence in accordance with this form of the invention both the syrup and the charged water are dispensed at constant velocity during the dispensing operation -so that a predetermined mixture of syrup and charged Water is assured regardless of the size of the mixed drink dispensed; The vent tube !38 maintains atmospheric pressure above the syrup in the fioat chamber !2!.

A clamping bracket is secured to the bottom: Wall 2or the cooling unit by means of screws !43. The clamping bracket :45 carries a screw clamp !41 for the purpose of securely mounting the cooling unit on a fountain bar !48 with a portion of the cooling unit overhanging the fountain bar. The gasket !5 seals the cooling-'unit to the fcuntain bar. A depending skirt !50 is suitably secured to the overhanging portionof the outer shell of the cooling unit and it is internally provided with a pair of guide brackets !5!. A hanger !52 is received within the skirt !50 and is provided with fianges !53 engaging the guide brackets !5l so that it may be vertically adjusted with respect to the skirt. Thehanger is provided with a ver ical slot i54 for receiving a screw and nut assembly !55 adjustably to position the hanger vertically with respect to the skirt. The hanger carries a hollow tray !56 provided with a reinforcing ange !51 and a spout !58. Any liquid which is spilled into the tray !56 is conveyed therefrom by the spout !58. A suitable disposal tube, not shown, may be secured to the spout !58.

The skirt !50 also carries a charged water shut off valve having a housing !60. The valve housing !60 is provided with an internal bore !6! and ashoulder !62. includes a valve seat !63 and a threaded exten sion !64, which extension is provided with longitudinal internal grooves !65. The threaded extension !64 is adapted to be coupled by a suitable coupling !61 to a charged water supply line !66. The side wall of the valve housing !60 is provided With a screw threaded opening !68 for receiving a nipple !69 to which is secured the cooling tube extension 29by means of a fitting !79.

Within the bore H! of the valve housing !60 there is slidably received a member m having a groove !12 for receiving a resilient O-ring !73 which operates to seal the member !H in the valve housing !60. The member H! is provided with a central valve guide !14. It is also provided with an internal shoulder !15 for the purpose of supporing a cylindrical screen !16 betweenit and the shoulder !52. Thus, charged water passing through the' shut off valve must pass through the cylindrical screen !16.

Slidably mounted within the screw threaded extension !64 is a valve head carrying a valve member Ils! adapted to engage the valve seat !63. A spring !82 located between 'the valve head !80 and a ported partition !83 secured in the threaded extension urges the valve member !8! against the seat !63. A valve stern !84 is slidably and rotatably received in the valve guide !14 and it is provided with a groove for receiving a resilient o-ring !85 for scaling the same. A spring ring !36 prevents removal of the valve stem. The inner end of the valve stern !84 engag es the valve head !83 and when the valve vetem is, pushed inwardly the valve member !Bl The valve housing also is moved, away from the valve seat !63, against the action of the spring !82. charged; water passes around the valve head !30 throu h, the longitudinal grooves !65 and then past the valve seat and through the screen !16. When the valve stem !84 is released the spring !82 moves thevalve member !8l against the valve seat !63 toshut off the flow of charged water. The outer end-of the valve stern !84.is provided with a han dle !Bl for manipulating the valve-Vetem.

The valve housing !60 is secured; to the skirt !50 by means of a pair of screws !90. A generally U-shaped plate s is secured in place by the same screws' !90, one screw passing through a hole in` the. plate; !9I and the other screw !90 passing through a slot in the plate 1 9!1 The plate IS! engages in a groove !973 in the member for looking the member-in position. The plate !9! is also provided with a hook !94 under which the handle !81 may be hooked To open the shut olT valve the valve stern !34 is pushed inwardly and the; handle rotated underneath the hoolr` !94 Whereby the valve stem 84 is held inwardly. To close the shut off valve the handle !81 is rotated from underneath the hook !94 and then the valve stern !34 is pushed outwardly by the spring !82. In order to disassemble thevalve for cleaning purposes, the plate IS! is rotated out of the position shown in Fig. 11, this being permitted by the slot !92. The plate !9-! is thus moved out of engagement with the groove !93 in the member E?! whereby the member !11, the valve stern !8 4 and the screen !76 may be removed from the valve housing.

The form of the invention' illustrated' in Figs. 1 3 to 19 is substantially thesame asthe form of the invention illustrated in Figs. 1 to 12 and like reference characters have been utilized for like parts. This form of the' invention difiers from the form of the invention previously described in two essential respects. One is in the manner of dispensing the syrup and the other is in the manner of mounting the cooling unit on thefountain bar.

Considering first therst difference, the syrup container is designated at 200 and is provided with a suitable cover 20!-. The bottom of the syrup container has an auxiliary chamber 292 in which is secured an extension 203, the upper edge of the extension 203 forming a seat 204. The extension 203- communicates with a syrup tube 205 provided at its end with a fitting 206 carrying a resilient O-ring 201. The fitting 206 is slidably received in the enlarged opening 94 of the ported member 42 so that the syrup tube may be removably received therein. The extension 203 rests upon the boss 39 for supporting the syrup container. A spring latch Zla is secured tothe bottom ,of the syrup container 2 3!) and engages the shoulder !9 of the cooling chest for securing the same in place. Here again the spring latch member 2!0 is manipulated by a link 2!! and handle 2 !3 guided by a bracket 2!2.

Movably located within the auxiliary chamber 202 is a measuring chamber 2!5 having a cover 2 6. The cover is secured in place by spring arms 2l'! and pins 2!8. The cover is provided with a vent tube 2l9 ex tending upwardly therefrom. The, measuring chamber 2 !5 is provided with an internal seat 220. The bottom of the measuring chamber 2 !5 is provided with a plate 22! for engaging the seat 204 formed by the upper edge of the extension 203. The plate 22! is provided with a central opening .22 2. The bottom of the plate ama-pos:

9\ 221" is provided withilateral projections223Zin' the form of a spider-for carrying a sleeve 22 4 having openings:225 therein. The lateralprojections 2 23 operateto guide the measuring chamber 2:! 51 with respect to the extension 2031 Located within the .measuring chamber 2 5 is a float' 226 which' in its downward. position engages the seat* 220' to seal off the'central opening 2'22 and.whi`ch in itsupper position engages stops 22'1'carried by the cover 2 I E of the measuring chamber.

Aa rod. 2'30 extends. inwardly l through the syrup tube205 and is adapted toengage the lower-end' oftthesleeve 22'4to tilt it to the positionshown in Fig.. 16 or to' allow itto' become vertically posi tioned as illustrated in Eig. 17. The outerrend'of the rod. 230: is Secured to the Valve stern 06'; bya pin23l. A valve head 232 is slidably mounted on the; rod 230 and carries a valve member' 233' adaptecl to engage theseat 39 of the' portedimem ber.: A" spring 234 urgcs the valve member 233 against'. the seat 89 and a. spring 235 urges the valvestem zinwardly, A resilient'oering 231is locatedtbetweenthe valve head 232: and: the valve stem 95 to limit the inward movementiof, the valve' stem 93; shoulder 23.8. ad'aptedto engage the valve head 23.2;formoving the Valve member 233 away from the va1veseat89 against the action of' thespring 23.4;

When the dspensing valve is closed, asilluszi.:

tratecl' in Figs. 16 and 19, the rod- 23.0 maintains the-measuring-chamber 2l5 in the tilted position, syruofillsthesyrup tube 205 and the extension 203 and; also entersthrough the central opening 222tofill the measuring chamber 2 [5 whereupon the; float- 226 is in theraised; position' as illustrated in Fig. 16. When the dispensingvalveis opened the valvestem 96 is movedoutwardly to pull the rocl 230; When this occurs the measuring-chamber 215 moves to thevertical positionas' illustrated in Fig; 17 and the plate 221; seats against the Valve seat 204'to' prevent syrup from being discharged from the syrup-container 203; When therod 230 is retracted the shoulder 23.3 engages the valve head: 232 to move the valve member 233:` away from the seat sesothatgsyrp may be dispensed. When this occurs, SYI'up fiows from` the measuring; chamber; 2|5- through: the: centralopening 22 2:unti1 the fioat zz engages the seat 220. When thisoccurs thefiow-of'syrup u is stopped even though the' Valve member 233- is: away from the-valve seat 39. Thus, a;measured quantity of syrup determined by ths-yrupcontained in' the measuring chamber- 2|5-` is: dispensed.
