Description:

This invention pertains to a drink cooling apparatus, and more particularly, to a compact cooling apparatus for drinks of a type that may be conveniently mounted on a soda fountain counter or shelf. I have found that the sale of drinks such as tomato juice, milk, orange juice, etc., can be very materially increased by displaying the particular juices or fluids in an attractive container of a type that may be conveniently positioned in plain view of customers. For this reason, I prefer to use containers that are at least partially transparent and can be conveniently made from suitable transparent material such as glass.

An object of the present invention has been to provide a new and improved form of apparatus or device of the type above-mentioned.

Another object of my invention has been to provide a dispenser container or device having a high efficiency and/or effectiveness of cooling action.

A further object has been to provide a cooling device having a cooling unit that can be employed to suitably agitate the fluids or liquids being cooled. These and many other objects of my invention will appear to those skilled in the art from the drawings, the description of the illustrated embodiments, and from the claims.

In the drawingsFigure 1 is a central vertical sectional view of a cooling device with portions thereof suitably sectioned; Figure 2 is a perspective view in elevation of a cooling element of the device or apparatus shown in Figure 1; Figure 3 is a view similar to that of Figure 4 showing a modified form of construction; Figure 4 is a top plan fragment taken along the line IV-IV of Figure 3 showing a detail of the device of Figure 3; Figure 5 is a top plan view of the cooling element of the device or apparatus of Figure 3; Figure 6 is a vertical sectional view showing a portion of a container broken away and a modifled form of cooler element that may be employed in connection with the embodiment of my invention shown in Figure 3; Figure 7 is a sectional view similar to Figures 1 and 3 showing a fragment of a modified form; Figure 8 is a fragment in plan showing a detail of Figure 3; Figure 9 is a view similar to that of Figure 1 but showing a modified construction; Figure 10 is a view showing a cover member; Figure 11 is a contracted top plan view of a detail of Figure 9; and Figures 12, 13, and 14 are vertical sections showing positioning and enclosing structure for an article such as shown in Figure 9.

Insofar as practical, for the purpose of simplifying the description of the invention, I have indicated similar parts by similar numerical designations. Modified parts are indicated by prime suffixes.

In the embodiment of my invention shown in Figure 1, 10 represents a somewhat barrel or rounded-like glass or transparent container having a suitable valve faucet 11 adjacent a lower end thereof for removing cooled liquids, and a circular or annular-like rim 12 adjacent a top edge thereof. A cooler element 13 preferably of some suitable metal such as aluminum is provided with a lower cylindrical-like portion and an upper outwardly-convexly-bulging curved portion that terminates in a substantially outwardly curved. flange 14. The flange 14 rests upon a bead, bearing flange, or edge 12 of the container and permits the cooling element 13 to be turned relatively thereto. For this purpose, a handle bracket or transverse piece 15 is secured to and extends across between opposite side edge portions of the upper end of the cooler 13.

It will be noted that the cooling element 13 is shaped in such a manner that the greater portion of the ice is concentrated adjacent the upper portion of the container 10; I have found this to be the most efficient arrangement from a heat transfer or thermal standpoint. That is, hot fluids or liquids normally tend to move towards the upper portion of a container and the cooler portion of the liquids toward the lower portion of the container. It is also apparent that the ice as it melts will form water and collect in the lower or cylinder portion of the element 13 where the cooling action need not be so great, due in effect, to the above explained stratification of the liquid being cooled in the container.

I have also found that there is a tendency for such liquids as tomato juice to precipitate or coagulate into heavier particles adjacent the bottom of the container. The natural result is a clogging of the outlet 1.1 and an initial drawing off of the more nutritious portions of the liquid.

This, of course, occurs after the liquid has been permitted to stand for a considerable time.

As shown particularly in Figure 2, I have provided the lower cylindrical portion of the cooler 13 with a pair of oppositely-extending wings or vanes 16. A rotation of the element 13 thus produces an agitation of the entire liquid in the container 10 and a greater agitation of the lower portions thereof. In this manner, the heavier or more nutritious coagulated materials are suitably mixed in an equal proportion throughout the entire liquid before drawing off through the faucet 11. Any suitable form of lid 17 (glass, ceramic, or metal) may be provided for simultaneously covering the container 10 and the ice within the cooling element 13. Separate lids may be provided, however, if desired.

In the embodiment of my invention shown in Figure 3, I have provided a modified form of lid 17' having a suitable motor 18 mounted thereon.

The motor 10, including the lid, is pivotally connected to a suitable rigid support 19 by a hinge or toggle joint 20 in such a manner that it may be swung above the container. A latch Blm8ent 21 cooperates with arm 19 and an arm 19' on the motor adjacent the pivot 20 for locking them in position with respect to each other when the motor is in an operating relationship with respedt to the cooling device. To thus prevent the motor from rising and becoming disconnected with the codling device, a motor shaft 22 having a quadrant or other suitable form of interlock end is adapted to engage with a substantially similarly-shaped complementary portion of the transverse bracket 15' of cooling element 13.

Also there is provided means to prevent rotary movement of the cover when the motor is driving said means comprising lugs 28 on the container which engage notches in the cover 17'.

The cooling element 13 is preferably mounted in such a manner that its flange 14' fits within an annular bead portion 12' of the container 10 and upon an inner race, bearing, or lip portion thereof. The connection 28-29 (see Fig. 8) supports the motor upon the top bead of the vessel 10 without interfering with the rotation of the cooler element 13. The cooling element 13 of Figure 3 has a stud or a pivotal bearing 30 at its bottom end adapted to seat in a bearing 31 of the container 10. The motor shaft and the pivotal bearing being in axial alignment of the cooling element, positions the cooling element centrally of the combination, avoiding contact with the side walls of the container 10.

In the modified form of container 13 shown in Figure 6, I have provided a propeller shaft 24 having a propeller 25 extending from the lower cylindrical end thereof and suitably journaled within bearings 26 and 27. The shaft 24 is preferably cut out or grooved with a drill-like groove in such a manner as to agitate the ice during its rotation. The propeller 25, of course, will take the place of the blades 16 of the construction shown in Figures 1, 2, and 3, and will not only prevent coagulation adjacent the bottom of the container, but will also prevent excessive strati- 6 fication of the liquid.

It will be apparent that suitable bearings or bearing .rings or washers may be interposed between the upper flanges 14 or 14' of the cooler element 13 and the mouth or annulus portions 6 of the container 10. For example, as shown in Figure 7, an annular ring or flange 14"' may be provided with a series of spaced-apart rollers 32 mounted therealong and adapted to roll in a race way of the container wall 12". Any other me- 7 chanical expedients may be employed in this connection since such features are not a part of the present invention.

Any suitable cooling agency such as ice or dry ice is employed in the cooling element 13. How- 7 ever, a freezing unit of the electrical or chemical type may also be employed; for small installations, however, the latter type of freezing unit is somewhat impractical.

In the modified construction of my invention shown particularly in Figures 9-11, inclusive, a vessel 33 of glass, ceramic or other suitable material, has been provided with a spigot 34 for dispensing the palatable liquids. The ice or other cooling material is placed in a centrallydisposed cooling element 53 of aluminum metal or other suitable similar material having a transversely-positioned handle bracket 54 secured thereto in a manner similar to the bracket 15 of the previously described embodiments. A concentric agitator cylinder or element 38 is positioned about the cooling element 53 and is providdd wiith suitable vertically and outwardly extending agitator fins or ribs 39.

As shown particularly in Figures 9 and 11, the agitator element or cylinder 38 is preferably provided with a pair of outwardly extending pins 40.

These pins may be weld-formed to extend radially outwardly from wall portions of the agitator element 38 or may be threaded, rivet-connected or secured in any other suitable manner.

The container is provided with an inwardlyextending cover flange 41 of metal or other suitable material that is mounted over the annular lip portions thereof and is slotted to by-pass the pin-like portions 40. In like manner, a centrally disposed cover member 42 having a handle portion 43 secured thereto and extending upwardly therefrom is slotted at 44, see Figure 10, to receive the pins 40. In this manner, the agitator element 38 may be turned by rotating the handle 43.

To increase the efficiency of thermal conductionl, as shown in Figuhe 9, I preferably provide a silitable fluid between the concentric walls of the cooler element 53 and the agitator element 38.

In Figure 12, I have shbwn a stand 58 of metal or other suitable material such as spun aluminum having an upwardly positioned and outwardly extending flange portion 59 for receiving and sul porting the bottom of the container 33.

I Figures 13 and 14, I have shown the container 33 provided with an opaque or metal cover plate 45 for concealing the liquids being dispensed. This cover member 45 cooperates with a secondary, outwardly and upwardly divergent flange portion 60, see Figure 14, in a specially designed type of stand 58'. It will thus be seen that the entire unit can be readily assembled and disassembled.
