This invention relates to cooling devices and more particularly refers to improvements in cooling devices having a chamber or housing adapted to receive and to partially at least enclose a liqaid or other container, such as a barrel, for instance, said housing having means therewithin for cooling the contents of the container positioned therein.

The primary object of the invention is to pro- 10 vide a cooling device for a container, such as a barrel, for instance, so constructed as to form with the outer surface of the container a cooling chamber, encircling the peripheral portion of said container, said chamber being provided with heat exchanging surfaces in close proximity to the said container surface, said heat exchanging surfaces forming part of acooling medium circulating system.

Another object of the invention is to provide a cooling device for a container, such as a barrel, for instance, said device being preferably usable also as a support for the container, and being so constructed as to form with the outer surface of the container a cooling chamber, partial- 1y at least surrounding said container, said chamber being provided with means for circulating a cooling medium in close proximity to the said container surface, said means being so arranged as to insure a maximum cooling efiiciency.

Still another object of the invention is to pro-- vide. a support for a container, such as a barrel, for instance, said support having a housing adapted to hold the container in a position, making it possible to conveniently withdraw the contents thereof, said housing forming with the outer surface of the container, a chamber partially at least surrounding said container, provided with means for circulating a cooling medium in close prox- 40 imity to the said container surface, said housing being so constructed as to permit ready insertion of the container therein or its removal there from. r

A further object of the invention is to provide a support for a barrel, forming therewith a cooling chamber partially at least surrounding the periphery of said barrel, said chamber being equipped with means for circulating a cooling ,medium in close proximity to the part of the barrel enclosed thereby, said support being of such "oiemployment of metallic pipes or receptacles for the discharge of liquid from the barrel, and thus precluding the possibility of the taste of the liquid withdrawn from the barrel being affected by contact with metallic surfaces.

A still further object isto provide a supporting and cooling device for barrels adapted to form with said barrel a cooling chamber partially at least enclosing the periphery thereof, said chamber being equipped with means for circulating a cooling medium in close proximity to the surface of said barrel, said support being of a simple and compact construction, and being preferably of a portable character so as to be adapted for domestic use in connection with beverages, such as beer, for instance, usually supplied in relatively small, easily handled kegs.

An additional object of the invention is to provide a support for a barrel of such construction as to hold the barrel in tilted position to aid in draining the contents therefrom, said support being provided with means for circulating a cooling medium in close proximity to the parts of the barrel enclosed by the support.

Still another object of the invention is to provide on the edges of the support contacting with the barrel, resilient members which, in conjunction with vthe barrel, serve to prevent access of outside air to the chamber containing the cooling medium circulating means.

An additional object of the invention is to provide a supporting housing for a barrel, adapted to form therewith a cooling chamber partially at least surrounding the peripheral surface of the barrel, said chamber being equipped with means for circulating a-cooling medium in close proximity to parts of the barrel enclosed thereby, said support being made of two sections connected together in such fashion that they can be separated to permit introduction of a barrel and then moved to enclose the barrel.

In the embodiment of the invention shown in the enclosed drawings, the support for a barrel consists of two similarly shaped sections hinged together along one longitudinal edge to permit separation of the two sections. These sections have an external configuration closely resembling the external configuration of a barrel in that their peripheral surfaces are given the same curvature as the peripheral surface of 'a barrel, but 10 their ends are cut away so that when the sections are closed with a barrel therewithin, the ends of the barrel will exte d slightly throughthe ends of the sections. e sections may be made of any suitable material, such as wood,

metal, etc., but preferably use is made of stain resisting metal for cleanliness and sanitation.

Within the bottom sections is permanently fixed a net-work made up of a plurality of interconnected'conduits which serve as a passage'for the circulation of cooling medium. In one form of the invention a plurality of interconnected conduits are hingedly secured to the lowersection so that they can be moved pivotally independently of the top section. These upper conduits are connected tothe lower conduits by means of flexible tubes so that the cooling'medium can be passed from the lower conduits into the upper conduits and then back to the lower section to pass therefrom to the agent serving to force circulation. In another form of the invention the uppersection has a plurality of interconnected conduits permanently aflixed therein,v so that when the upper section is moved pivotally the conduits move therewith. Again use is made of flexible tubular connections so that the cooling medium can be circulated, first throughthe conduits in one section, and then through the conduits in another section. I

ln'the preferredformof the invention the con-' duits are spaced from the walls of the sections and liner sheets of configuration similar to the configuration of the section walls. are spaced from the section :walls sothat insulating material can be placed between the section walls and the liners. I These liners preferably are made of metal, but other material may be used advantageously. .The lower section is provided with a drain outlet communicating,with the liner there in, whereby it is possible todrain any condensed moisture from this section.

Other features, advantages, and objects of the invention will become apparent by reference to the following detailed descriptiontaken in con- "junction with the accompanying drawings formingfa part of the same, wherein:

Fig. 6 is a detailed view of portions of conduits used for circulating cooling medium.

.Referring now to the drawings, upper and lower sections of a supporting member are indicated at 10 and'll respectively. The top section 1 0 is composed of a longitudinal wall 12 preferably of curvature conforming to the curvature of a barrel, such as for example, a beer barrel. To the ends of thewall 12 are secured end walls 14 and 15. The lower section 11 is provided with a longitudinal wall 16 similar in configuration to the wall 12 and with end walls 17 and 18. The

end wa1ls14, 15, 17 and 18 have their inner edges of substantially semi-circular configuration as at 19 so that when the sections are closed as in Fig'. 2, annular rings will be formed of pairs of end walls at therespective ends of the sections,'with the walls 14 and 1'7. as one pair and the walls 15 and 18 as another pair. While the longitudinal walls and the end walls of the two v sections have been shown .in the drawings as beving constructed of wood, it is to be understood which it can be secured. By this arrangement of outer} wall and liner, 2. space of. uniform height is provided in which is placed insulating material 20 which may be any suitable material having good thermal insulating properties. The lower section 11 is provided with a liner 21 simi-'- lar to the liner 19 and with a space in which is placed insulating material 22 similar to insulating material 20.

Positioned in the lower section 11 is a network of conduits- 25 so interconnected by means of elbows 26'that a continuous passage is provided from'one extreme conduit to the other for the circulation of suitable cooling medium. These conduits 25 extend immediately above the liner 21 in such fashion as to provide a network which conforms to the outline and the shape of the liner 21, and, of course, to the walls 16. The network of conduits can be permanently secured in lower section 11 in any desired fashion.

In the-form of the invention shown in Fig. 1, use is made of a network of conduits. 25 shaped in the same fashion as the network in the lower section, and due to the use of couplings 26 the network so iormed will be more or, lessselfsustaining. As the result of this construction;

-'it is possible to hinge the upper network to the lower section by means of'hinges 40.

It will benoted in Fig. l'that a barrel is broken lines, while some of the pipes of the upshown in position in partially heavy lines and-partially per network are shown in heavy lines in position I covering substantially the top half of the peripheral surface of the barrel. Since this upper network is hingedly connected to the lower section, it is possible to swing the networkout of obstructing position so that a barrel can be placed in the lower section or-removed therefrom.

All of the conduits 25 are provided with fins 44 in the nature of thin strips of metal extending around each conduit. in spiral fashion along the length thereof. These fins aid in cooling articles supported within the twosections.

An inlet pipe 45 leads from suitable compressing and circulating mechanism, not shown,

through the end wall 1'1 into communication of the network and is connected to a flexible tube 48, which in turn is connected to an outlet pipe 49 passing through the end of the wall 1'1 and,

section 11 to the other end wall 1'7 thereof, at

which point it may be bentdownwardly as at 51 to be embedded in the wall 16. .If desired,

however, it may be secured directly to the end wall 1'! inthe same fashion as it is secured tothe end wall 18. This protecting bar is in a slightly higher position than the network of conduits, so that it will prevent contact between a barrel and these conduits.

Since condensed moisture will collect within the support, it is necessary to provide means for withdrawing the same, especially when the support is being defrosted. A drain 52 communicates with the lowest point of the liner 21 and extends outwardly through the end wall 17. A valve can be provided therefor, if desired.

In the form of the invention shown in Fig. 5, the network in the lower section is arranged in. the same fashion as in Fig. .1. However, the network for the top of the barrel to be chilled is not independently hingedly mounted but is permanently fastened within the upper section 10 in the same fashion as the lower network is fastened in the lower section 11. Again use is made of a flexible tube 46' for communication between an extreme conduit of the lower network and an extreme conduit of the upper network, and use is made of a return pipe 47' communicating with a flexible tube 48' which is connected to the outlet pipe. Strips of good thermal insulating material 60 are secured to each edge of the walls of the ficiently to insure proper draining of the con-.

tents thereof. The top section 10 may be provided with an eye 67 to which is fastened either permanently or removably a rod 68 to serve as a prop for holding the upper section in partially open position if desired.

The operation and use of the device is substantially as follows: Assuming that it is resting on a horizontal surface, such as a counter, bar, etc., with the prop 65 in the position shown in Fig. 4, the device may be made ready for the reception of a barrel of suitable contents, such as, beer, by moving the upper section 10 about the axis of its hinges sumciently to render access to the lower section. If the device is as shown in Fig. 5, the upper network of cooling conduits will be carried along with the top section, since this network is permanently secured thereto. However, if the network is arranged as shown in Fig. 1, it will be necessary to move this network plvotally about the axisof the hinges 4c an amount sufficient to render the lower section accessible.

A barrel B is then positioned in the lower section in the fashion shown in Fig. 4 with the spigot S arranged to be at the lowermost possible point. The upper network may then be moved pivotally to overlie the barrel after which the upper section 10 is moved pivotally to complete the enclosing of the longitudinal expanse of the barrel. Of course, if the arrangement shown in Fig. 5 is used, the step of swinging the upper network is. omitted. The two sections are then clamped together by means of clamps 36, after which the device is in condition to cool the contents of the barrel. The coolingmedium enters through the inlet 45, passes through the lower network of conduits and into the upper network of conduits, after which it leaves the device through the outlet 49 to be returned to the compressing and circulating apparatus. The contents of the barrel can be withdrawn at any desired time through the spigot S and if necessary a vent V can be provided for the barrel. After the contents have been entirely withdrawn from the barrel, it can be removed from the device by reversing the steps previously stated, that is, by unlocking the clamps 36, swinging the cover about its axis, and if necessary, swinging the network of conduits about its axis.

The provision of a structure in which the longitudinal walls conform in shape to the longitudinal wall of a. barrel and in which the conduits for circulating cooling medium have a corresponding curvature, makes it possible to cool the contents of the barrel with maximum eiiiciency.

The provision of the resilient strips of insulating material at all edges which contact with other edges or with the barrel, assure that the air space within the cooling device will be substantially dead air space when the barrel is positioned therein so that cooling is greatly facilitated. Of course, the device may be made in a number of different sizes, but inasmuch as barrels are of more or less standard sizes, it will be seen that, no difllculty will be experienced in positioning any number of barrels of a specified size in a proper support. To compensate for any slight irregularities for barrel configuration, the protecting bar 50 is provided which assures that contact between the barrel surface and the conduits of the lower network will be prevented.

The invention is particularly advantageous for the dispensing of certain beverages, which whenever possible should be maintained at a low temperature and served directly from the barrel. For instance, beer should desirably be served on tap from the barrel, as when it is caused to flow through metallic pipes before being served it acquires a disagreeable metallic taste, which is highly objectionable.

On the other hand, it must be recognized that since beer barrels are usually made of rather heavy wood stock, a very energetic cooling action must be exerted in order to lower the temperature of the contents of the barrel to the desired point and in a relatively short time; so that a cooling action entailing the use of ice or so-called freezing mixtures would be entirely unsatisfac-. tory from a practical standpoint; while the use of any wall or partition interposed between the cooling surfaces and the surface of the barrel would seriously impair the cooling efficiency at the apparatus.

From the foregoing it will be seen that the t invention provides a now, simple, novel and eflicient device for cooling the contents of barrels, which device can be manufactured inexpensively and which will operate with a minimum of expense. It will be evident that modifications can be made without departing from the spirit of the invention, in view of which it is to be understood that the invention is not to be limited by the illustrated embodiments but is to be of conduits within said chamber adjacent to and directly facing the surface of the barrel enclosed by said housing, said conduits forming a passage for cooling medium, said network of conduits conforming to the transverse peripheral and longitudinal curvature of the barrel.
