- This application May 18, 1966, Ser. No. 550,889 14 Claims. (Cl. 222-58)
- This invention relates to beverage dispensers, and more particulary to a system for mixing and dispensing beverages, either carbonated or noncarbonated beverages.
- an improved system of the class described adapted to hold a supply of a beverage readymixed for dispensing, and to replenish this supply in response to dispensing of a quantity (a drink) of the beverage by automatically mixing water and syrup to replenish the quantity of beverage dispensed; the provision of such a system adapted for dispensing carbonated and noncarbonated beverages; the provision of such a system adapted for dispensing carbonated beverages of different degrees of carbonation; and the provision of such a system adapted for use either for manual dispensing of beverages or coinoperated vending of beverages.
- FIG. 1 is a diagrammatic representation of a system of this invention.
- FIG. 2 is a wiring diagram.
- Tap water is supplied to the inlet of the pump 5 via a line 13 which includes a filter 15.
- a line 17 which includes a solenoid valve 19 connects the outlet of the pump to the carbonator 3.
- the arrangement is such that on operation of the pump and with valve 19 open, tap water is pumped into the carbonator 3.
- Carbon dioxide gas (CO) is supplied to the carbonator from a tank 21 via a line 23 Which includes a pressure regulator 25 and a solenoid valve 27.
- the CO gas mixes with the water in the carbonator to provide carbonated water having a high carbonation factor, i.e., water having several times its volume of CO gas .therein (i.e., high carbonated water).
- a line 29 extends from the carbonator to a stabilizer tank 31.
- This tank 31 holds a supply of high carbonated water for feeding the system, the supply being replenished as required from time to time by operation of the unit 1.
- Tank 31 is a pressure tank, and pressure of CO gas in this tank is utilized to deliver high carbonated water therefrom through a main high carbonated water delivery line 33 as required.
- Line 33 which includes a pressure regulator 35, extends from the tank 31 to a high carbonated water manifold 37.
- two carbonated water delivery lines CL1 and CL2 branch off from the manifold 37 for delivery of carbonated water to pressure vessels or mixers M1 and M2.
- Each of these is adapted to hold a beverage under pressure, and defines a closed mixing chamber or zone in which admixture of the water and syrup may occur.
- each of mixers M1 and M2 is supplied with syrup for admixture with the carbonated water supplied thereto to form a mixed carbonated beverage.
- Each of lines CL1 and CL2 includes a check valve 39 and a flow control valve 41.
- a third beverage vessel or mixer is indicated at M3.
- a tap or plain water line PL including a solenoid valve 43 and a flow control valve 41, is interconnected between the outlet of pump 5 and mixer M3.
- a by-pass line 45 including a pressure relief valve 47 interconnects line PL downstream from valve 43 back to the pump inlet.
- syrup tanks 5T1, STZ and ST3, for three difierent flavors are provided, one for each of the respective mixers M1, M2, M3. These syrup tanks are pressurized from the CO tank 21 via a line 49 including a pressure regulator 51 and having branch connections 53 to the syrup tanks.
- Syrup supply lines SL1, SL2 and SL3 interconnect the syrup tanks and the respective mixers M1, M2, M3.
- Each of lines SL1, SL2 and SL3 includes a check valve 55 and a flow control valve 57.
- Each check valve 55 prevents back flow in its respective line, and each flow control valve 57 provides for a substantially constant rate of flow of syrup despite variations in the pressure differential across the flow control valve.
- the needle valve in bleeder B1 may be adjusted to bleed plain water into line CL1 at a relatively low rate such as to bring the carbonation factor of the carbonated water delivered to mixer M1 down to 3.5
- the needle valve in bleeder B2 may be adjusted to bleed plain water into line CL2 at a relatively high rate such as to bring the carbonation factor of water delivered to mixer M2 down to 2.0.
- Syrup of the first flavor is delivered from syrup tank ST1 into the mixer M1 via line SL1 to mix with the incoming carbonated water from line CL1 in themixing zone provided by the mixer M1, thereby to replenish the amount of beverage of the first flavor which is dispensed.
- the syrup is delivered from tank ST1 on account of the drop in pressure in syrup line SL1 which occurs on opening of dispensing valve D1., enabling CO pressure in tank ST1 to force syrup out of this tank.
- Flow control valve 57 in syrup line SL1 provides for flow of the syrup at the appropriate rate in order to deliver the amount of syrup needed in proportion to the amount of carbonated water.
- valve S1 Upon closing of dispenser valve D1 when the cup C has been filled, switch S1 closes back on itsupper contact, to reopen valve 19. Valve 43 is deenergized and recloses. If switch CS is closed on its upper contact, meaning that thereis no demand for water from carbonator 3, motor 7 is deenergized, and valve 27 is deenergized and closes. If, however, there is a demand for water from carbonator 3, switch CS will be closed on its lower contact. Under these circumstatnces motor 7 will remain energized to continue driving the pump 5, and valve 27 will remain energized and open.
- the pump 5 will then deliver water through line 17 (valve 19 being open) to the carbonator 3, and CO gas will be delivered to the carbonator from tank 21 via line 23 (valve 27 being open) until the carbonator 3 is full, whereupon switch CS closes on its upper contact to cut off the motor and close valve 27.
- switch S2 When dispensing valve D2 is opened for dispensing a carbonated drink of the second flavor into a cup at C, switch S2 is thrown onto its lower contact. As before, this results in deenergization of valve 19 to close it and energization of valve 43 to open it. Assuming switch CS is closed on its upper contact (carbonator 3 full), motor 7 is energized to drive the pump 5 and valve 27 is energized to open. Plain water in line PL is pressurized. Carbonated water is driven out of tank 31 and through line CL2 into the mixer M2 'and forces the ready-mixed beverage of the second flavor out through line BL2 and valve D2 into the cup until valve D2 is closed.
- Carbonated water in amount corresponding to that dispensed into the cup is supplied to mixer M2 to make up for the amount dispensed.
- Syrup of the second flavor is delivered from syrup tank ST2 into the mixer M2 via line SL2 to mix with incoming carbonated water from line CL2 in the mixing zone provided by the mixer M2, thereby to replenish the amount of beverage of the second flavor which is disclaimedd.
- the syrup is delivered from tank ST2 on account of the drop in pressure in syrup line SL2 which occurs on opening of dispensing valve D2, enabling CO pressure in tank ST2 to force syrup out of this tank.
- Flow control valve 57 in syrup line SL2 provides for flow of the syrup at the appropriate rate for delivering the amount of syrup needed in proportion to the amount of carbonated water.
- switch S2 Upon closing of dispenser valve D2, switch S2 closes back on its upper contact, thereby opening valve 19 and closing valve 43. If there is no demand for Water from carbonator 3, motor 7 stops and valve 27 closes. If there is a demand, motor 7 remains in operation and valve 27 remains open until the demand is satisfied, as above described.
- switch S3 When dispensing valve D3 is opened for dispensing a noncarbonated drink of the third flavor into a cup at C, switch S3 is thrown onto its lower contact. As before, this results in deenergization of valve 19 to close it and energization of valve 43 to open it. Assuming switch CS is closed on its upper contact (carbonator 3 full), motor 7 is energized to drive the pump 5 and valve 27 is energized to open. The pump 5 thereupon pumps plain water through line PL tothe mixer M3, and this forces the ready-mixed noncarbonated beverage of the third flavor out through line BL3 and valve D3 into the cup until valve D3 is closed.
- Plain water in amount corresponding to that dispensed into the cup is supplied to mixer M3 to make up for the amount dispensed.
- Syrup of the third flavor is delivered from syrup tank ST3 into the mixer M3 via line SL3 to mix with incoming plain water from line PL in the mixing zone provided by mixer M3, thereby to replenish the amount of noncarbonated beverage of the third flavor which is dispensed.
- the syrup is delivered from tank ST3 on account of the drop in pressure in syrup line SL3 which occurs on opening of dispensing valve D3, enabling CO pressure in tank ST3 to force syrup out of the tank.
- Flow control valve 57 in syrup line SL3 provides for flow of the syrup at the appropriate rate for delivering the amount of syrup needed in proportion to the amount of plain water.
- switch S3 Upon closing of dispenser valve D3, switch S3 closes back on its upper contact, thereby opening valve 19 and closing valve 43. There should be no demand at this time for water from carbonator 3, and hence motor 7 stops and valve 27 closes.
- the disclosure herein of the system with provision for dispensing of two carbonated beverage-s and one noncarbonated beverage is by way of example only. It may be adapted for dispensing any number of beverages (within practical limits). For example, it may be augmented to dispense more than two carbonated beverages by the addition of carbonated water lines extending from the manifold 37 to additional mix rs of the same type as used at M1, M2 and M3, and With beverage lines extending from the added mixers to additional dispensing valves, and additional syrup tanks.

Louis, Mo., a corporation of Delaware Continuation of application Ser. No. 402,229, Oct. 7, 1964.
This application May 18, 1966, Ser. No. 550,889 14 Claims. (Cl. 222-58) This invention relates to beverage dispensers, and more particulary to a system for mixing and dispensing beverages, either carbonated or noncarbonated beverages.
This application is a continuation of co-pending application, Ser. No. 402,229, filed Oct. 7, 1964, and now abandoned.
Among the several objects of this invention may be noted the provision of an improved system of the class described adapted to hold a supply of a beverage readymixed for dispensing, and to replenish this supply in response to dispensing of a quantity (a drink) of the beverage by automatically mixing water and syrup to replenish the quantity of beverage dispensed; the provision of such a system adapted for dispensing carbonated and noncarbonated beverages; the provision of such a system adapted for dispensing carbonated beverages of different degrees of carbonation; and the provision of such a system adapted for use either for manual dispensing of beverages or coinoperated vending of beverages. Other objects and features will be in part apparent and in part pointed out hereinafter.
7 The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.
In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,
FIG. 1 is a diagrammatic representation of a system of this invention; and
FIG. 2 is a wiring diagram.
Corresponding reference characters indicate corresponding parts throughout the several views of the draw- 1ngs.
Referring to the drawings, first to FIG. 1, there is generally indicated at 1 a water carbonating unit 1, comprising a carbonator 3, a water pump 5 and an electric motor 7 for driving the pump. The carbonator 3, pump 5 and motor 7 are mounted on a platform 9 which is pivoted at 11 in such manner that the weight of the carbonator (and water therein) is brought to bear on a double-throw control switch CS, with the arrangement such that when the carbonator is full of carbonated water, the switch actuator is pressed down to throw the switch on to its upper contact as shown in FIG. 2. When carbonated water in the carbonator drops below a predetermined level, the right end of the platform 9, as shown in FIG. 1, swings up to release the switch actuator, effecting closure of the switch on to its lower contact as viewed in FIG. 2. This results in operation to bring the level of carbonated water in the carbonator back up to a predetermined level to be main tained therein, as will appear.
Tap water is supplied to the inlet of the pump 5 via a line 13 which includes a filter 15. A line 17 which includes a solenoid valve 19 connects the outlet of the pump to the carbonator 3. The arrangement is such that on operation of the pump and with valve 19 open, tap water is pumped into the carbonator 3. Carbon dioxide gas (CO is supplied to the carbonator from a tank 21 via a line 23 Which includes a pressure regulator 25 and a solenoid valve 27. The CO gas mixes with the water in the carbonator to provide carbonated water having a high carbonation factor, i.e., water having several times its volume of CO gas .therein (i.e., high carbonated water). A line 29 extends from the carbonator to a stabilizer tank 31. This tank 31 holds a supply of high carbonated water for feeding the system, the supply being replenished as required from time to time by operation of the unit 1. Tank 31 is a pressure tank, and pressure of CO gas in this tank is utilized to deliver high carbonated water therefrom through a main high carbonated water delivery line 33 as required.
As shown in FIG. 1, three syrup tanks 5T1, STZ and ST3, for three difierent flavors, are provided, one for each of the respective mixers M1, M2, M3. These syrup tanks are pressurized from the CO tank 21 via a line 49 including a pressure regulator 51 and having branch connections 53 to the syrup tanks. Syrup supply lines SL1, SL2 and SL3 interconnect the syrup tanks and the respective mixers M1, M2, M3. Each of lines SL1, SL2 and SL3 includes a check valve 55 and a flow control valve 57. Each check valve 55 prevents back flow in its respective line, and each flow control valve 57 provides for a substantially constant rate of flow of syrup despite variations in the pressure differential across the flow control valve.
Means is provided for adjustably bleeding plain water into the carbonated water delivery lines CL1 and CL2 for adjusting the degree of carbonation of carbonated water delivered via these lines to mixers M1 and M2. In this regard, it will be understood that certain drinks, such as cola drinks, require relatively high carbonated water (e.g., water having from 3.5 to 4.0 times its volume of CO gas therein) and others, such as fruit-flavored drinks, require relatively low carbonated water (e.g., water having from 2.0 to 2.5 times its volume of CO gas therein). Various high carbonated drinks may also require high carbonated water having different high carbonation factors, and various low carbonated drinks may also require low carbonated water having different low carbonation factors. As shown in FIG. 1, this means comprises bleeder lines B1 and B2 interconnecting plain water line PL and lines CL1 and CL2, respectively, each of these bleeder lines including an adjustable needle valve 59 and a check valve 61. By suitable adjustment of the needle valves B1 and B2, plain water may be allowed to bleed into lines CL1 and CL2 between the check valve 39 and the flow control valve 41 in lines CL1 and CL2 at a rate such as to bring the carbonation factor of carbonated water delivered to mixers M1 and M2 down to a desired value. For example, if carbonated water in tank 31 and manifold .37 has a carbonation factor of 4.2, the needle valve in bleeder B1 may be adjusted to bleed plain water into line CL1 at a relatively low rate such as to bring the carbonation factor of the carbonated water delivered to mixer M1 down to 3.5, and the needle valve in bleeder B2 may be adjusted to bleed plain water into line CL2 at a relatively high rate such as to bring the carbonation factor of water delivered to mixer M2 down to 2.0.
Extending from the outlets of mixers M1, M2 and M3 are beverage delivery lines BLl, BL2 and BL3. As shown in FIG. 1, lines BL1, BL2 and BL3 terminate at dispensing valves D1, D2, D3, each having a nozzle 63 for delivering the beverage dispensed on opening thereof into a cup indicated at C. Valves D1, D2 andD3rnay be manually operated in the case of a manual beverage dispenser, or may be electrically operated in the case of a coin-operated beverage vendor. They are herein described as manually operated valves for purposes of illustration.
The beverage delivery lines BLl, BL2 and BL3 pass through a cooling tank 65 for cooling the beverages therein. This tank 65 may be a conventional sweet-water bath, containing a cooling coil which freezes water in the tank into a block of ice. Other suitable cooling means may be provided for cooling the beverages between the mixers and the dispensing valves.
Referring now to FIG. 2, dispensing valves D1, D2 and D3 are shown to control three double-throw switches S1, S2 and S3, each having a blade normally closed on an upper contact when the respective valve D1, D2 or D3 is closed, and moving on to a lower contact when the respective valve D1, D2 or D3 is opened for the dispensing of a beverage. These switches have their upper contacts interconnected in series across electric power supply lines L1 and L2 with thepump outlet solenoid valve 19 as indicated at 67, the arrangement being such that valve 19 is energized and open when all three switches are closed on their upper contacts. (i.e., when all of valves D1-D3 are closed). When any switch S1, S2 or S3 is thrown on its lower contact upon opening the respective dispensing valve D1, D2 or D3, valve 19 is deenergized and closes.
Switches S1, S2, S3 have their lower contacts interconnected in series across lines L1 and L2 as indicated at 69 with the plain water valve 43 so that, whenever any switch S1, S2 or S3 is thrown on its lower contact upon opening the respective dispensing valve D1, D2 or D3, valve 43 is energized to open. Motor 7 and the CO valve 27 are interconnected with the lower contacts of switches S1, S2 and S3 and the upper contact of switch CS as indicated at 71 in such manner that, wheneverany switch S1, S2 or S3 is thrown on its lower contact, and switch CS is closed on its upper contact, motor 7 is energized and valve 27 is energized to open. The lower contact of switch CS is connected to line L1 as indicated at 73 so that, whenever switch CS is closed on its lower contact, motor 7 and valve 27 are energized, but neither valve 19 nor valve 43 is energized.
Operation is as follows:
It will be understood that in normal operation of the dispensing system, there will be a ready-mixed supply of carbonated beverage of a first flavor standing under pressure in mixer M1 and in line BL1 from mixer M1 to dispensing valve D1. There will be a ready-mixed supply of carbonated beverage of a second flavor standing under pressure in mixer M2 and in line BL2 from mixer M2 to dispensing valve D2. There will be a ready-mixed supply of uncarbonated beverage standing in mixer M3 and in line BL3 from mixer M3 to dispensing valve D3.
When dispensing valve D1 is opened for dispensing a carbonated drink of the first flavor into a cup at C, switch S1 is thrown onto its lower contact. This results in deenergization of valve 19 to close it. It also results in energization of the plain water valve 43 to open it. Assuming that carbonator 3 is full of carbonated water and switch CS is closed on its upper contact, the stated actuation of switch S1 also results in energization of motor 7 to drive the pump and energization of CO valve 27 to open it. With valve 19 closed, valve ,43 open, and valve D3 closed, plain water in line PL is put under pressure and plain water delivered by the pump is recirculated through the pump via by-pass line 45, except for such small amount as may bleed through bleeder line B1. Pressure of CO in tank 31 drives carbonated water out of tank 31 through line 33, manifold 37 and through line CL1 into the mixer M1 and forces the ready-mixed beverage of the first flavor out through line BLl and valve D1 intothe cup until valve D1 is closed when the cup has been filled. Carbonated water in amount corresponding to that dispensed into the cup is supplied to mixer M1 to makeup for the amount dispensed. Syrup of the first flavor is delivered from syrup tank ST1 into the mixer M1 via line SL1 to mix with the incoming carbonated water from line CL1 in themixing zone provided by the mixer M1, thereby to replenish the amount of beverage of the first flavor which is dispensed. The syrup is delivered from tank ST1 on account of the drop in pressure in syrup line SL1 which occurs on opening of dispensing valve D1., enabling CO pressure in tank ST1 to force syrup out of this tank. Flow control valve 57 in syrup line SL1 provides for flow of the syrup at the appropriate rate in order to deliver the amount of syrup needed in proportion to the amount of carbonated water. As carbonated water flows through line CL1 to the mixer M1, plain water bleeds into line CL1 via the needle valve 59 in bleeder line B1 at a rate dependent on the setting of this needle valve, so that carbonated water with the desired carbonation factor is delivered to the mixer M1.
Upon closing of dispenser valve D1 when the cup C has been filled, switch S1 closes back on itsupper contact, to reopen valve 19. Valve 43 is deenergized and recloses. If switch CS is closed on its upper contact, meaning that thereis no demand for water from carbonator 3, motor 7 is deenergized, and valve 27 is deenergized and closes. If, however, there is a demand for water from carbonator 3, switch CS will be closed on its lower contact. Under these circumstatnces motor 7 will remain energized to continue driving the pump 5, and valve 27 will remain energized and open. The pump 5 will then deliver water through line 17 (valve 19 being open) to the carbonator 3, and CO gas will be delivered to the carbonator from tank 21 via line 23 (valve 27 being open) until the carbonator 3 is full, whereupon switch CS closes on its upper contact to cut off the motor and close valve 27.
When dispensing valve D2 is opened for dispensing a carbonated drink of the second flavor into a cup at C, switch S2 is thrown onto its lower contact. As before, this results in deenergization of valve 19 to close it and energization of valve 43 to open it. Assuming switch CS is closed on its upper contact (carbonator 3 full), motor 7 is energized to drive the pump 5 and valve 27 is energized to open. Plain water in line PL is pressurized. Carbonated water is driven out of tank 31 and through line CL2 into the mixer M2 'and forces the ready-mixed beverage of the second flavor out through line BL2 and valve D2 into the cup until valve D2 is closed. Carbonated water in amount corresponding to that dispensed into the cup is supplied to mixer M2 to make up for the amount dispensed. Syrup of the second flavor is delivered from syrup tank ST2 into the mixer M2 via line SL2 to mix with incoming carbonated water from line CL2 in the mixing zone provided by the mixer M2, thereby to replenish the amount of beverage of the second flavor which is dis pensed. The syrup is delivered from tank ST2 on account of the drop in pressure in syrup line SL2 which occurs on opening of dispensing valve D2, enabling CO pressure in tank ST2 to force syrup out of this tank. Flow control valve 57 in syrup line SL2 provides for flow of the syrup at the appropriate rate for delivering the amount of syrup needed in proportion to the amount of carbonated water. As carbonated water flows through line CL2 to the mixer M2, plain water bleeds into line CL2 via the needle valve 59 in bleeder line B2 at a rate dependent on the setting of the needle valve, so that carbonated water of the desired carbonation factor is delivered to the mixer M2.
Upon closing of dispenser valve D2, switch S2 closes back on its upper contact, thereby opening valve 19 and closing valve 43. If there is no demand for Water from carbonator 3, motor 7 stops and valve 27 closes. If there is a demand, motor 7 remains in operation and valve 27 remains open until the demand is satisfied, as above described.
When dispensing valve D3 is opened for dispensing a noncarbonated drink of the third flavor into a cup at C, switch S3 is thrown onto its lower contact. As before, this results in deenergization of valve 19 to close it and energization of valve 43 to open it. Assuming switch CS is closed on its upper contact (carbonator 3 full), motor 7 is energized to drive the pump 5 and valve 27 is energized to open. The pump 5 thereupon pumps plain water through line PL tothe mixer M3, and this forces the ready-mixed noncarbonated beverage of the third flavor out through line BL3 and valve D3 into the cup until valve D3 is closed. Plain water in amount corresponding to that dispensed into the cup is supplied to mixer M3 to make up for the amount dispensed. Syrup of the third flavor is delivered from syrup tank ST3 into the mixer M3 via line SL3 to mix with incoming plain water from line PL in the mixing zone provided by mixer M3, thereby to replenish the amount of noncarbonated beverage of the third flavor which is dispensed. The syrup is delivered from tank ST3 on account of the drop in pressure in syrup line SL3 which occurs on opening of dispensing valve D3, enabling CO pressure in tank ST3 to force syrup out of the tank. Flow control valve 57 in syrup line SL3 provides for flow of the syrup at the appropriate rate for delivering the amount of syrup needed in proportion to the amount of plain water.
Upon closing of dispenser valve D3, switch S3 closes back on its upper contact, thereby opening valve 19 and closing valve 43. There should be no demand at this time for water from carbonator 3, and hence motor 7 stops and valve 27 closes.
It will be understood that the disclosure herein of the system with provision for dispensing of two carbonated beverage-s and one noncarbonated beverage is by way of example only. It may be adapted for dispensing any number of beverages (within practical limits). For example, it may be augmented to dispense more than two carbonated beverages by the addition of carbonated water lines extending from the manifold 37 to additional mix rs of the same type as used at M1, M2 and M3, and With beverage lines extending from the added mixers to additional dispensing valves, and additional syrup tanks. It will also be understood that the system is adapted for use in the coin-operated vending of beverages by providing for electric actuation of the dispensing valves under coin control, and timing the interval of opening each dispensing valve to dispense a cup of the beverage.
In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
