s claims. (ci. 22a-17) This invention relates to a. method of and apparatus for handling, transporting, cooling, storing, and dispensing beverages, and has particular reference to a method and apparatus of this character for use especially in connection with gas charged beverages, such as beer, ale, and the like.

In order that brewed gas containing beverages such as beer and ale may be dispensed to the consumer in the state or condition intended by the producer or brewer, it is essential that from the time the beverage leaves the brewery and until it is served to the consumer, it be transported, stored, and otherwise handled under definite standards of temperature, pressure, and cleanliness or sanitation. Furthermore, it is considered by many to be important that for a considerable period prior to the actual dispensing of the beverage that the s ame be maintained in a quiescent state and not subjected to unnecessary turbulence or agitation.

'Under conventional arrangements for merchandising brewed beverages such as beer and ale the brewer substantially loses control over the handling and storing of his product after he has delivered kegs or barrels containing the beverage to his retailing customer or distributor. There is, accordingly, a definite need for a beverage handling method and equipment which will enable the brewer to supervise or control the treatment accorded his product until the same is dispensed or served to the consumer. In addition to the brewers lack of control and supervision over the product according to conventional beverage handling systems, he is required 'to make a substantial investment in shipping or transportation containers, such as barrels, kegs and similar cooperage. One reason for this large cooperagev outlay is because the tavern keeper or other retailer of draught beverages usually maintains on hand, in order to meet the demands of his trade, a number of kegs of beverage. Since it is inconvenient and impractical for the beverage distributor or brewer to make frequent calls at his customers places of business, the present practice usually results in a considerable number of kegs or barrels being placed with each retailer or dealer, many of such kegs remaining empty for long periods of time` between visits of the brewers representative. The care accorded the empty kegs or containers by the retailers is not always of the highest order and the brewer is accordingly required to make large expenditures on repairs and replacement of cooperage thus injured. Additionally, kegs of beverage delivered but not yet placed on tap are often subjected to adverse temperature conditions that frequently injure the beverage before the same is tapped for dispensing.

It is, therefore, one aim of the present invention to provide a novel method of handling, storing, cooling, and dispensing beverage and an apparatus for carrying out such method that will reduce the investment and upkeep costs oi! a brewer or producer of beverage and` also afford him a large measure of control over his product until the same is served to the ultimate consumer.

Another object of the invention is to provide improved apparatus or equipment for receiving and storing the beverage on the premises of the retailer or at the place of dispensing so as to keep such beverage under proper conditions of temperature, pressure, and general sanitation. More specically, the invention aims to provide beverage handling equipment which occupies a minimum of space and includes improved means for refrigerating the stored beverage and maintaining thereon an adequate pressure for retaining in the beverage the essential gases which contribute to the taste and palatability of the beverage.

Another object is to provide in a compact unit. beverage storing'and dispensing equipment which is neat in appearance and occupies a minimum of space.

Another object of the invention is to provide an improved method of and apparatus for handling, storing, and dispensing beverage which enables the producer or brewer to deliver his product to the retailer, transfer the same to containers or receptacles permanently installed at the place o dispensing, and immediately return the transportation container or containers to the brewery or other place of manufacture of the beverage.

Another and more specific object is to provide a method and apparatus of the above character which is adapted to quickly and efciently effect the transfer of beverage from the transportation container to the storage receptacle and which can be operated by attendants or other agents without requiring separate training or skill.

A still further object of the invention is to provide a generally improved beverage handling method and a generally improved apparatus for carrying out such method which is relatively simple in design and construction and inexpensive to manufacture. Other objects and advantages will!A become apparent from the following detailed escription of suitable embodiments of the inven ion made in connection with the accompanying drawings, in which like parts throughout the several views are indicated by like or corresponding letters and numerals of reference.

Pursuant to the broader aspects of the invention, beverage is placed by the brewer or producer in kegs, barrels, or other transportation.

containers indicated in the drawings at T. The brewers agent or delivery man takes the lled transportation containers to the establishment nf the retailer or other place of dispensing and there transfers the entire contents of one or more transportation containers T to storage or dispensing receptacles R (RI and R2 of Figs. 1 and 2). This transfer is eiected by evacuation of the gas from the receptacle R and an application of pressure to the transportation container T by means of a pump P driven by suitable means such as an electric motor M. A valve V is provided to control the evacuation of and the application of pressure to each of the storage or dispensing receptacles R. In Figs. l and 2 the valves V are indicated at VI and V2 for the receptacles RI and R2, respectively. 'I'he storage receptacles R are immersed in a bath of cooling liquid contained in an insulated cabinet C and beverage is withdrawn from the receptacles from time to time as desired for consumption through faucets F carried b-y a chambered upper cabinet or bar B.

In the embodiment of the invention shown in Figs. 1 and 2, the cabinet C may be formed of inner and outer sheet metal casings I and 2, respectively, which are maintained in spaced apart relation and the intervening space lled with suitable linsulating material 3. The upper bar B may also be formed of inner and outer sheet metal casings 4 and 5, respectively, which can be integrally connected to the casings i and 2 of the cabinet if desired so as to form a sturdy and fluid-tight unit assembly. Preferably, the casings for the cabinet and bar are formed of corrosion-resistant material such as stainless steel or galvanized sheet metal. Desirably, the outer casings are treated with paint or other surface decoration and preservative. As shown in Fig. 2, the insulation 3 extends upwardly between the casings 4 and 5 of the bar B so that coolant 6, forming the bath for the receptacles R, may be insulated from the atmosphere throughout its depth and up to the top of the bar. The bar B is surmounted by an insulated top I hinged at 8 which provides access to the chamber within the bar and cabinet for repairing or otherwise servicing the beverage handling equipment contained therein. The coolant 6 may be any suitable liquid such as water or brine. In most cases water will be suitable since the temperatures employed for beverages such as beer and ale do not fall below its normal freezing temperature.

The receptacles R may be formed of any of numerous strong heat conducting materials, such, for example, as stainless steel or other corrosion-resistant material. For example, ordinary sheet metal may be used, the inside being coated with porcelain enamel, lined with glass,

or otherwise treated to resist chemical action between the receptacle lining and the beverage and to present a smooth, slick surface adaptable to iiush cleansing in the manner to be hereinafter described. Although the shape of the receptacles R is not critical, it is preferable that they utilize to the maximum the available space within the cabinet C so as to reduce the relative iioor space required for the quantity of beverage stored. It is therefore intended to make the receptacles RI and R2 approximately square or rectangular in horizontal cross section so that side walls 9 thereof are substantially uniformly spaced from the inner casings I of the cabinet.

The bottoms I0 of each of the receptacles is concave or dished so as to provide for drainage toward an outlet II, preferably centrally located. This outlet communicates with a downwardly slanting drain conductor I2 embedded in the insulating material 3 and terminating in an outlet fitting I 4 which includes a valve I5 and is disposed at the bottom of the cabinet C on the bartenders side thereof. Suitable legs I6 are provided for the receptacles R to support the latter in spaced relation with respect to the bottom of the cabinet C, thus permitting the coolant 6 to circulate under the bottoms I0 of the receptacles.

In top Il of each receptacle is a relatively large opening or clean-out hole which is normally covered by a cap or closure member I8 suitably secured in place, such as by means of threads I9. Extending approximately vertically through the closure I8, preferably through the center thereof, is a conduit 20 which terminates at its lower end (normally within the receptacle) in a fluid distributing head or spray nozzle 2|. As shown in Fig. 2, the opening in the top of the receptacle is approximately centrally located so 'that the spray nozzle 2I is likewise centered in the receptacle and accordingly adapted to distribute cleaning liquid or detergent uniformly in radial directions upwardly against the top I1 so that thel liquid flows downwardly over all parts of the inside of the receptacle, as will later appear. An extension 22 of the conduit 20 extends upwardly through the cabinet and bar B and through the wall of the latter, terminating in a connection iitting 23 which includes a shut-oil valve 35.

The outlet conductor I2 has a branch 24 which extends upwardly through the cooling liquid chamber in the cabinet C and bar B, terminating in the faucet F which is mounted on the bartenders side of the bar B. Thus the conduit I2 through which beverage is drawn to be dispensed through the tap or faucet F is wholly immersed in the cooling liquid 6 so as to insure the proper temperature conditioning of the beverage as the same is withdrawn from the system for consumption. If desired, the conduit I2 may be formed with a coil portion 2l, also immersed in the coolant, which affords additional cooling capacity and prevents the dispensing of warm beverage even when the temperature of the beverage in the receptacle R is above that desired.

A conductor or coil 28 for carrying a suitable refrigerant is coiled around the upper portions of the receptacles RI and R2 and suitably supported in the coolant chamber of the cabinet. One or more turns of the refrigerant coil may be carried upwardly and across the chamber in the bar B, as indicated at 21. A suitable refrigerating unit comprising a compressor 28 and drive motor 29 is housed in a chamber 30 formed in an extension portion of the cabinet C at one end of the latter. This compressor unit is arranged to circulate refrigerating liquid through the conductors 2B and 21 so as to cool the liquid 6 in which the refrigerant conductors are immersed, in accordance with well known practice. The operation of the compressor or refrigerating unit is controlled by means of a thermal responsive bulb 3l immersed in the coolant 6 at the bottom of the chamber in the cabinet C and connected to an electric switch, that controls the electric motor 29, through a conductor 32. The refrigerating unit is set or adjusted so that the coolant t is maintained at a uniform temperature suitable ior dispensing of the particular beverage being handled. In the case of beer and ale this temperature is usually considered to be between :u

about 35 F. to about 37 F.

Suitably mounted in the compartment 30 above the refrigerating unit, as, for example, on a shelf or platform 33, is a pumping means for gas, which includes the pump P and the drive motor M conage is charged, and is also utilized for the purpose of evacuating one or both of the receptacles when the same are to be lled with beverage and for supplying gas under under pressure to the transportation containers T to force beverage from the latter into one or both of the storage receptacles.

Referring to Fig. 3, the arrangement of the conductors for connecting the several parts of the apparatus will now be described. In this ligure is shown the receptacle RI, together with its associated conductors and valves, it being understood that a similar arrangement of parts is provided for receptacle R2. Each of the two receptacles, and its associated control devices with the pump means and refrigerating apparatus, constitutes a complete dispenser, but they are connected in parallel with the pump means. Outlet 31 of the pump P is connected by a fluid or gas conductor 38 to a reservoir 39 which receives' and stores gas under pressure, a' check valve 40 being provided in the conductor 38 to prevent the reverse flow of gas from the reservoir 39 to the pump P. Electrical energy for running the motor M is received from a suitable source of supply through conductors LI and L2 which are connected to the motor M through electrical conductors 4I and 42, a pressure switch 43 being interposed in the conductor 42. The switch 43 is responsive to pressure in the reservoir 39 and is arranged to start the motor M to drive the compressor or pump P when the pressure in the reservoir 2l falls below a predetermined amount and to stop the motor M when the pressure in the reservoir exceeds a predetermined amount. Thus, for maintaining the gas pressure in the reservoir 39 between predetermined limits, the operation of the compressor or pump P is substantially automatic. The precise pressure limits are not critical, variations being permissible to suit the requirements of particular kinds of beverage and the capacity of the receptacles serviced by the pump means. For usual needs in dispensing a beverage such as beer, a pressure of from about 15 to about 2O pounds, more or less, has been found satisfactory. For a purpose to be later explained, a manual switch 44 is provided in parallel with the switch 43, so that the compressor P can be started and stopped at the will of the operator or attendant.

'I'he valve means VI includes a pair of movable valve bodies 45 and 46 mounted'in a suitable housing indicated at 41. These movable valves, which are preferably rotatable although valves of the slide type may be employed, are of the multiple position variety and are each adapted to effect a number of different connections or arrangements of the several fluid conductors with which they are associated.

Inlet 48 of the pump means P is connected by a tubular conduit 49 to a port in the valve housing 41 which communicates through a iirst passage 50 in the valve body 46 with a passage 5I formed in the housing 41. By means of a passage 52 in the valve body 45 the housing passage 5I is placed in communication with a port to which is connected a tubular conduit 53 connected into the extension 22 of the conduit 20. ln this manner when the movable valve bodies 45 and 46 are in the full line positions shown in Fig. 3, the inlet 48 of the pump means P is placed in communication with the interior of the storage and dispensing receptacle Rl, so that actuation of the pump withdraws air or gas from the beverage receptacle.

A tubular conduit 56 connected to the conduit 38 between the pump outlet 31 and the check valve 40 is connected to a port in the valve housing 41 which may be placed in communication with an atmospheric outlet passage 51 through a second passage 58 in the movable valve body 46. As shown in Fig. 3, the passages 50 and 58 in the valve body 46 are so arranged that they make their respective connections just described when the valve body is in the full line position illustrated. When thus connected and the pump mea-ns P is started by manually closing the control switch 44, or otherwise. air or gas is withdrawn from the receptacle RI, and, if the 'reservoir 39 is full, may be discharged to the atmosphere through the outlet 51 in the valve housing 41, as will later appear. During this withdrawal o f gas or air from the receptacle the faucet F, and the valve 35 are closed so that atmospheric air is not drawn into or admitted to the system, and the check valve 40 prevents reverse now of gas out of the reservoir 39, thus retain.- ing the pressure therein. A valve 82 is provided in the tubular conduit 58 so that gas or air drawn out of the receptacle R by the pump means P, instead of being released to the atmosphere through the control Valve and outlet 51, is forced through the check valve 40 into the reservoir 39 and thence into the transportation container T. In this manner the air or gas evacuated from the storage and dispensing receptacle is used to apin capacity to ll a number of receptacles.

ply a positive pressure on the beverage in the transportation container to force such beverage into the storage and dispensing receptacle. valve 82 can, of course, be opened, when necessary, to release excess gas or air from the system.

To introduce beverage into one of the receptacles R, a transportation container T containing the beer or other beverage to be transferred is connected to the fitting I4 by means of a flexible conduit 59. This conduit is connected to hand valve 6I at the top of a tap rod 6I) which extends to the bottom of the transportation container T,. as shown by the broken lines of Fig. 2.

As is well known, beer and other-carbonated beverages are normally maintained under considerable pressure in the transportation containers in which they are supplied to the retailer at the place of dispensing by the brewer or producer. Therefore, upon opening the valves I5 and 6| 'with the flexible conduit 59 connected as aforesaid, the gas pressure Within the transportation container T forces beverage through the tap rod 60, conduit 59, and upwardly through the outlet opening II, into the bottom of the receptacle R. A

The flow of the beverage from the transportation container T to the storage and dispensing receptacle R is hastened and assisted by introducing gas under pressure into the transportation container T from the storage and dispensing receptacle R or the reservoir 39, a tubular conductor 62 permanently installed in the dispensing. unit being provided for this purpose. This conductor terminates in a connector fitting B3 on the bartenders side of the bar or cabinet, to which is attached a flexible conduit 64 leading to a conventional tap rod and gas supply fitting or connector 65 attached to the top of the transportation container T and through which is inserted the tap rod 60. A shut-off valve 66 is provided for the conduit 62 adjacent the tting 63 so that the conduit may be closed to prevent the escape of gas from the reservoir 39 when the flexible conduit 64 is disconnected and the transportation container T removed. A valve 61 on the gas connector fitting 65 controls the flow of gas into and out of the transportation container in the usual manner.

The entire contents of the transportation con tainer T is transferred preferably to one of the receptacles R in a single transferring operation, although it is contemplated to provide larger transportation receptacles which will be sufncient completion of the transferring operation, the valves l5 and 6I are closed, permitting the ilexible beverage conductor 59 to be disconnected and removed from the fitting |4 and tap rod 60.

Valves 66 and 61 are also closed, permitting thev exible gas conduit 64 to be disconnected from the fittings 63 and 65 and removed. Thus the transportation container T can be immediately returned to the brewer and only remains at the place of dispensing a suflicient length of time to transfer its beverage content to one of the storage receptacles R. In most cases this time interval will be but a few minutes, so that arrangements can be made for the brewers representative or delivery yman to make the necessary connections of the conduits 59 and 64 and supervise the beverage transferring operation. Accordingly, the brewer maintains control over the beverage until it is placed in the refrigerated receptacles at the place of dispensing and his product is not subjected to the careless handling and The' Upon A neglect that might result if the transportation containers containing the beverage were left at the place of dispensing to be handled by the retailers representatives.

Immediately upon the completion of the beverage transferring operation and as soon as the valve I5 is closed, the valve bodies 45 and 46 are moved or rotated from the first or full line positions shown in Fig. 3 to approximately the dotted line position illustrated. When thus positioned, the passage 52 in the valve body 45 connects the conduit 53 to a port in the housing 41 which is connected by a tubular conduit 68 to the high pressure conduit 62 previously mentioned. In this manner high pressure air or gas from the reservoir 39 is immediately admitted to the receptacle R to place the transferred Abeverage therein under suilicient pressure to retain the u gas content with which the beverage is charged.

Movement of the valve body 46 to the dotted line position shown in Fig. 3 places the pump inlet conduit 49 in communication with the valve passage 51 (to the atmosphere) through the previously mentioned second valve passage 58. Accordingly, a demand for gas or air in the reservoir 39, which starts the pump P, is supplied from the atmosphere through the conduit 49. When the valve body 46 is rotated to the dotted line position shown, the rst passage 50 places the high pressure tubular conduit 56 in communication with the passage 5| in the valve housing 41. However, the previous or simultaneous movement or rotation of the valve body 45 to the dotted line position shown seals the port `to the passage 5| so that the escape or flow of high pressure gas through the conduit 56 is arrested. Accordingly, gas or air forced through the conduit 38 by the pump P flows through the check valve 40 into the reservoir 39. The valve means VI and also the valve means V2 must both be arranged to close or seal their respective conduits 56 in order that the pump may be effective to force gas or air into the reservoir 39. Hence when one of the receptacles is being lled or replenished in the manner previously described, the pump may force the air or gas withdrawn therefrom into the reservoir 39, or into one of the transportation containers being emptied.

When all of the beverage has been dispensed from one of the receptacles, the outlet valve I5 is opened and a suitable means provided for receiving drainage from the receptacle. A conduit 69, connected to a suitable source of fluid or liquid cleanser, such as a solution of any well known detergent and water, is aixed to the fiting 23 and the valve 35 is opened, allowing the liquid detergent under pressure tc flow through conduit 22 and into the receptacle R through the spray or liquid distributing head 2 I. The head 2| directs the inowing detergent mixture upwardly and outwardly against thetop ofthe receptacle. The liquid detergent then ilows downwardly and evenly over the side walls of the receptacle to the bottom I0 and out the central opening or outlet II. During this ow of the liquid detergent, the top, sides, and bottom of vthe receptacle are thoroughly cleansed and the residue left by the beverage is eiectively removed. Afted the completion of the Washing of the 1eceptacle by the liquid detergent, a suitable conduit (not shown) from a sourceof water is connected to the valve fitting 23 and the receptacle ilushed with fresh clear water which removes all traces of the detergent.

Prior to the cleansing and iiushing of the empty receptacles the valve bodies 45 and 46 are shifted from their second position, indicated by the dotted lines in Fig. 3, to their third or flushing position indicated by the broken lines of Fig. 3.

In this position the valve body 45 seals the port to the conduit 53, preventing the ow of liquid detergent and flushing or rinsingwater into the valve and also the flow of gas from the reservoir 38 through the tubular conduit 68. 'I'he valve body 46 seals the ports to the tubular conduits 49 and 56, preventing the flow of air or gas through these parts of the conduit system.

When the flushing of the receptacle is completed the valves I and 23 are closed and the valve bodies 45 and 46 are moved to their first position, indicated by the full lines' of Fig. 3. The apparatus is then ready to receive another supply of beverage from a transportation container or containers.

In the above description the valve bodies 45 and 46 have been -treated or described as separate elements of a valve system. It is, however, contemplated that they may be connected together for simultaneous actuation by a single control element. For example, the valve body 45 may be provided with a control arm and the valve body 46 provided with a control arm 1i. The control arms 10 and 1| may in turn be connected by a link 12 forsimultaneous actuation of the valve bodies 45 and 46.

If desired, the valve bodies 45 and 46 of each of the control valves V may be combined in an integral movable or rotatable valve body 15, Figs. 5, 6, and 7. 'Ihis valve body is of substantially cylindrical form and is rotatably mounted in la housing 16 which corresponds to the housing 41y previously mentioned. The housing is provided with a cylindrical bore 11 which rotatably receives the valve body and the latter is retained in place by a cover l18 threaded into the housing and provided with a central opening 19 in which is rotatably journaled an extension or shaft portion 80 of the valve body, on which is secured an actuating handle 8|, by means of which the valve body may be rotated to its three operative positions previously described.

The surface of the valve body is cut away, in the plane indicated by the line 6-6 of Fig. 5, to provide the passage 52 previously mentioned and is cut away, in the plane indicated by the line 1--1 of Fig. 5, to provide the rst and second passages 50 and 58 previously mentioned. The housing 16 is cored out or otherwiseprovided with passages to effect connection between the several conduits previously mentioned and to provide the ports which communicate with the passages 50, 52 and 58. The conduits or tubular conductors 49, 53, 56 and 68 are secured in sockets formed in the rear side of the housing 16, or in any other suitable manner customary in the art, and communicate with the valve body passages through openings or passages formed in the housing.

The unit multiple position valve illustrated in Figs. 5 through 'I is arranged, through 4actuation. of the single control handle or lever 8l, to connect the receptacle R. alternatively to the intake 48 and the outlet 31 of the pump P. Furthermore, this valve, in one position, connects the receptacle with the pump intake and the pump outlet with the atmosphere, while in a second position closes the pump outlet to the atmos phere, causing the pump to feed the gas reservoir, and connects the receptacle with the gas reservoir so that gas under pressure may flow into the lcool the liquid 6 which is maintained at ajsufdciently high level to keep the beverage dispensing conduits 24 wholly immersed. Preferably the liquid level extendsfabove the faucets FI and F2.

v The valves VI and V2, for the receptacles Rl and R2, respectively, and which are constructed as illustrated in` Figs. 5 through '1, are moved to the first position previously described so that the conductors 53 from the receptacles are connected to the inlet or intake openings 48 of the pump P. Motor M is then set in operation by manually closing the switches 44 so that the pump means is driven to withdraw air or gas from the receptacles.

Beverage is brought to the place of dispensing in one or more of the transportation containers T. One of these containers is connected to the receptacle RI as shown in Fig. 2 and in the manner previously described, and the valve I5 is opened to allow the beverage to flow into the receptacle Rl from the transportation container. This flow is uniform and even, being substantially without turbulence or undue agitation since it enters the receptacle from the bottom and the level thereof rises evenly in the receptacle until the transferring operation is completed. The valve 66 may be opened and the.valve 82 closed to apply a gas pressure to the beverage in the transportation container and assist the transfer. This feature is important since although the beverage in the transportation container may be under considerable pressure when received at the place of dispensing, the pressure therein decreases as the beverage is transferred to the receptacle. Therefore, the supplying of additional gas pressure to take the place of the beverage flowing out of the trasnportation container is desirable.

In a similar manner beverage is transferred from the same or a different transportation container or containers to the receptacle R2. In each case when the transferring operation has been completed, the valve l5 and 66 are closed and the multiple position valves Vi and V2 are shifted to their second position. in which the gas under pressure in the reservoir 38 is admitted to the receptacles to substantially immediately apply sufficient pressure on the transferred beverage to retain therein the gas with which the beverage is charged. The attendant then opens the manual switch 44 so that the control of the pump motor M is by means of the automatic switch 43, which insures a supply of air or gas in the reservoir 39 at the correct pressure.

As previously mentioned, the` transportation containers T may be disconnected from the dispensing apparatus as soon as the transferring operation is completed, which in most instances requires but a few minutes. It is to be noted that the controls and attaching connections for connecting the transportation containers to the several conduits of the system are all located on the cabinet C and bar B and readily accessible to the attendant. Thus the connecting of the trans=I portation containers for purposes of transferring beverage may be effected with expedition.

In some instances it may be desired to transfer in succession the contents of a plurality of transportation containers to one of the receptacles.

This willbe particularly true where the receptacles are located in a large retailing establishment where considerable quantities of beverage are sold. For example, it may be desirable to have storage and dispensing receptacles which receive and store the contents of from two to six or more .half barrels of beer or ale. Accordingly, when the contents of one keg or transportation container has been transferred to the receptacle, the valves I and 66 are closed, the empty transportation container T removed, and a full transportation container substituted in its place, after which the valves I5 and 66 are again opened to transfer the contents of the second transportation container to the storage and dispensing receptacle. This procedure can be repeated until the contents of as many transportation containers as desired have been transferred to the receptacle.

When one of the receptacles RI or R2 has been emptied of beverage, the corresponding control valve V is shifted to its third position, such as diagrammatically represented by the broken lines of Fig. 3. This position of the valve, as previously mentioned, closes the conduit 53 and prevents liquid detergent and ushing water introduced through the conduit 22 and valve 35 from flowing through the control valve V and into the remainder of the system. The empty receptacle is then cleaned and flushed. as previously -described, and is ready to receive a fresh supply of beverage.

The transportation container T may be connected to the system immediately ,after the receptable R has been emptied and cleansed.

After the removal of the transportation container the pressure of air or gas applied to the storage and dispensing receptacle R forces into the beverages gases that may have escaped during the transferring operation, thus restoring the beverage to substantially its original state as prepared by the brewer.

While one of the receptacles is empty and is being cleansed, beverage may be dispensed as usual from the other receptacle, there being suicient capacity in the reservoir. 39 to supply gas or air under pressure to the receptacle from which beverage is being dispensed.

Fig. 4 illustrates a modification of the invention in which bar BI is located a considerable distance above or removed from the cabinet CI'. For example, the bar may be located in the tap room on one iloor of a tavern or other similar establishment while the cabinet CI may be located in another room or on another floor of the building. A large tubular conductor 83, preferably insulated, extends upwardly from an apertured fluid-tight top 84 secured on the cabinet CI through a conduit 88 extending upwardly through the conduit 83 and having an inlet end 89 disposed near the top of the chamber in the bar BI just below surface 98 of the coolant 6. Outlet 9I of the circulator 86 discharges coolant through a conduit 92 into the body of coolant within the cabinet CI. When the circulator 86 is in operation, coolant from the cabinet CI flows upwardly through the conduit 83 around the beverage conduits 24 and into the chamber of the bar BI. The coolant at the top of the chamber in the bar is drawn into the inlet 89 of the conduit 88 and downwardly by the circulator through the conduit 88.

While the circulator may be maintained in continuous operation, it is preferable, for reasons `of economy, that it only be operated from time to time as the demand for coolant arises in the bar chamber. The circulator 86 may be a conventional liquid pump mounted on and driven by an electric motor 95 which is supported on the cabinet CI. This motor is energized from a vsuitable source of electric current through conliquid 6 adjacent the surface 98 thereof in the and is connected to a tubular fitting 85 secured in the bottom of the bar BI. The connections of the conduit 83 to the bar and cabinet are made liquid-tight so that the cooling liquid 6 may extend from the cabinet CI upwardly through the conduit 83 and into the chamber of the bar BI. The beverage vconduits 24 are carried upwardly from the receptacles R through the conduit 83 and are connected to the faucets F in the manner previously described. As in the embodiment of the invention first described, the beverage conduits 24 are wholly immersed throughout their length in the refrigerated coolant 6, which is cooled by a refrigeratlng unit in the manner previously described.

A coolant circular 86 is mounted on the cabinet CI and has an inlet B'I which receives coolant in the chamber of the cabinet CI.

chamber of the bar BI. The switch 96 is series connected in the conductor 98 which, with conductor 99, supplies electric current from the conductors LI and L2 to the motor 95,. When the coolant 6 in the bar chamber falls below a predetermined temperature the bulb 91 actuates the Yswitch 96 to close the circuit energizing the motor 95. The driven circulator 86 then draws the relatively warm liquid from the top of the bar chamber down through the conduit 88 and discharges the same into the relatively cold body of liquid This action of the circulator also forces cold liquid up through the conduit 83 to replace the warm liquid in the bar chamber.

If desired, a suitable supporting table or counter may be provided to support the bar BI and the same may have a conventional drain board I8I. As shown in Fig. 4, only the faucet or faucets F need be carried by the bar BI in the tap room of the tavern or other dispensing establishment. The control valves V with the connector fittings and valves 35 and 66 may be mounted onthe cabinet C which is kept or installed in the basement or yother room of the establishment. When thus installed, the brewer can arrange to supply beverage to the retailer and the brewers own agents can personally make the transfer of the beverage from the transportation containers T to the storage and dispensing receptacles R. This service or supplying of fresh beverage may be carried out by the brewers agents or `delivery men without the necessity for them to enter the tap room of the retailer and without interrupting or disturbing the normal handling of beverage by the bartender in the tap room.

From a consideration of the drawings and the above description it is apparent that the present invention provides a novel method and apparatus for handling, storing, cooling, and dispensing beverages, particularly gas containing beverages like beer and ale. The method permits a close control of temperatures and pressures on the beverage so that its characteristics which determine its flavor and palatability'may be controlled by the brewer or manufacturer. The method contemplates and the apparatus provides means for quickly and eiiiciently transferring the entire contents of a transportation container to a storage and dispensing receptacle from which the gas is removed as the beverage is introduced therein under pressure. The single pump means is uniquely arranged with a novel valve structure or structures so that it may be. utilized in withdrawing air or gas from the storage and dispensing receptacle as well as for the purpose ci applying a pressure on beverage to be transferred or beverage to be dispensed.

The storage of the beverage is in containers which are maintained at a uniform temperature proper for preserving the beverage and for minimizing secondary fermentation of a beverage such as beer and ale. Included in the` apparatus is a unique arrangement for facilitating the cleansing of empty receptacles before they are filled with a fresh supply of beverage. This feature of the invention enables the public to obtain a more sanitary beverage which has improved characteristics of taste and palability.

The principles of the present invention may be utilized in various Ways, numerous modiilcations and alterations being contemplated, substitution of parts and changes in construction being resorted to as desired, it being understood that the embodiments shown in the drawings and described above are given merely for purposes of explanation and illustration without intending to limit the scope of the claims to the specific details disclosed.
