BEER COOLER Fi le'd Nov. 18, 1957 2 Sheets-Sheet i Attorneys Inventor Patented Oct. 24, 1939 UNITED STATES PATENT FFiCE 1 Claim.

The present invention relates to new and use- I ful improvements in beer dispensing means of the type wherein the beverage is maintained under pressure in a container at a point remote from the discharge faucet, such as in a basement or lower floor.

The primary object of the invention is to provide, in a manner as hereinafter set forth, novel means for cooling the beverage while in transit from the container to the faucet.

Other objects of the invention are to provide a beverage cooler of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein;

Figure 1 is an elevational view, showing the device installed.

Figure 2 is a view in vertical section through the cooler.

Figure 3 is a view in vertical section through the upper portion of the cooler, showing an elbow which carries the faucet or spigot mounted therein.

Figure 4 is a view in horizontal section, taken substantially on the line 44 of Fig. 2.

Figure 5 is a horizontal sectional view, taken substantially on the line 55 of Fig. 2.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comp-rises a cooling tube I of suitable metal on the end portions of which substantially duplicate upper and

lower fittings

2 and 3, respectively, are fixed. The

fittings

2 and 3 comprise smooth sockets 4 in their inner ends in which the end portions of the cooling tube I are fixed. An inlet neck 5 communicates with the cooling tube I adjacent the lower end thereof. In their outer ends, the

fittings

2 and 3 are provided with threaded sockets 6.

Extending between the

fittings

2 and 3 in the cooling tube I and spaced therefrom is a beverage conduit I of suitable material. Suitable spacers 8 are provided between the beverage conduit I and the cooling tube I. As illustrated to advantage in Fig. 2 of the drawings, the end portions of the beverage conduit I project into the sockets 6 and are encircled by resilient washers or gaskets 9.

Thereference numeral Ill designates a tubular jacket which is mounted on the cooling tube I in spaced, concentric relation thereto. The jacket '6 Iii terminates in a closed lower end I I above the inlet neck 5 of the tube l. The upper end portion of the jacket it is fixed on the lower portion of the fitting 2. The tube i communicates at its upper end portion with the jacket Ill through openings or ports l2. A discharge neck I3 is provided on the lower end portion of the jacket II].

Threadedly mounted in the socket 6 of the upper fitting '2 is an elbow it which communicates with the beverage conduit I. The gasket 9 in the fitting 2 prevents leakage between the elbow I4 and the conduit l. The reference numeral I5 designates a conventional spigot which is mounted on the elbow i i. At an intermediate point, the elbow I l has formed therein a vertical opening I6 which is aligned with the conduit 1. This facilitates the insertion of a suitable brush or other device for cleaning the conduit I. A removable plug l1 closes the opening I6.

In Fig. 1 of the drawings, the reference nu- 25 meral i8 designates a plurality of beer kegs having cooling coils I9 mounted therein. The reference numeral 26 designates a heat insulated header which is connected to a suitable pump or compressor (not shown) for receiving refrigerated water therefrom. The delivery pipe 2| of the header 2i? is connected by flexible conduits 22 to the nipples or necks 5 of the tubes I. The discharge nipples it of the jackets II] are connected by flexible conduits 23 to the intake ends 35 of the coils it. The discharge ends of the coils I9 are connected. by conduits 24 to the return pipe 25 of the header 26. The reference numeral 26 designates tap rods in the kegs I8. Flexible conduits 2? connect the rods 26 to the lower fittings 3 of the cooling devices in communication with the conduits I of said devices.

It is thought that the operation of the invention will be readily apparent from a consideration of the foregoing. Refrigerated water from a compressor flows through the delivery pipe ZI of the header 28 and enters the cooling tubes I of the devices through the flexible conduits 22 and the inlet nipples 5. Of course, one of the cooling devices is provided in the delivery line from each keg 8. The refrigerated water flows upwardly around the conduit I in the tube I and enters the jacket it through the ports I2. Of course, the Water then flows downwardly in the jacket I 0 and is discharged through the nipple I3.

Upon leaving the cooling devices, the water flows through the flexible conduits 23, through the coils IS, the conduits 24, the pipe 25 of the header 20 and returns to the compressor. It will thus be seen that novel means has been provided for maintaining the beverage at the desired temperature while in transit to the spigot or faucet as well as when it may be standing in the line.

It is believed that the many advantages of a beer cooler constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within. the scope of the invention as claimed.

What is claimed is: v

A heat exchange unit for use with a beverage containing keg having a tap rod therein, a header for the intake and discharge of cooling fluid under pressure, and a cooler coil in the keg connected at one end to the intake side of the header; said unit comprising a cooling tube having upper and lower end fittings closing the same and outlet ports therein adjacent the upper end thereof, a draft tube of smaller and uniform diameter extending axially through the cooling tube and forming therewith a cooling chamber substantially coextensive in length with that of the cooling tube, the lower end fitting being adapted for the connection of said draft tube to the tap rod for the passage of the beverage from the keg upwardly through said draft tube, an overflow jacket surrounding the cooling tube, an inlet nipple at the lower end of said cooling tube for connection to the discharge side of the header whereby ccoling fluid from the latter may rise in said cooling tube to discharge out of said ports into said jacket, the jacket having a closed lower end spaced above said lower end fitting and said inlet nipple being connected to the cooling tube between said lower end of the jacket and said lower end fitting for the introduction of the cooling fluid directly into the cooling tube, and a discharge nipple extending from the lower end of said jacket for connection to the other end of said coil whereby overflow fluid in said jacket may discharge back into said coil to flow back to the intake side of the header.
