2 Claims, (Cl. 257-7192) This invention relates to a cooler construction. More particularly it relates to an arrangement by which a dry storage tank is held within another tank containing a cooling uid, which dry storage tank is preferably easily removed for a variety of requirements.

In certain types of cooler construction it is the custom to place a dry storage tank adapted to contain articles to be cooled within another tank, cooling uid and cooling coils occupying the space between the tanks. With such construction, the buoyant force of the cooling iiuid tends t push the dry tank up out o! the tank, and some means for holding the dry tank in place is required when this tank is not completely filled so that the weight o! the material being cooled will hold the tank in place.

An object of the present invention is to provide an improved coler construction.

A further object is the provision of a construction by which a dry storage tank is removably held within an outer tank containing a cooling fluid against the buoyant force of the cooling fluid.

According to the present invention a dry storage tank is positioned within an outer tank containing a cooling medium. The dry tank is held within the outer tank by means of bracket members which extend respectively from the two tanks and are secured to one another.

In the drawing:

Figure 1 is a view partially in section, showing the improved cooler construction;

Figure2 is a view taken along the lines 2-2 of Figure 1 with parts removed;

the tank I3 along with the coils I4. The buoyant force of the duid tends to push the tank I3 up out of the container l0, and, consequently, some means for holding the tank within the container is required.

This means includes a bracket formed desirably of sheet metal and having a main portion 2l provided with an elongated slot 22 and base portions 23 extending from opposite sides of the portion 2l and provided with slots 2l. This bracket 20 is secured, as shown in Figures 1 and 2, by means of its base portions 23I to the inner side of the tank I0 by means of bolts v25 extending through -theslots 24. The point of securement of the bracket 20 to the tank I0 by means of the bolts 25 is immediately below the top of the support I5 carrying the cooling coils I4, and the portion 2| of the bracket extends up over the Figure 3 is a side elevation of a bracket adapted to be connected with the outer tank of the cooler;

Figure 4 is an end elevation of the same;

Figure 5 is a side elevation of a bracket adapted to be connected to the inner dry tank of the cooler; and,

Figure 6 is an end elevation of the same.

The cooler of the present invention includes an outer tank or container I 0 having a filler of suitable insulation II. Resting within the outer tank on supports I2 is -an inner dry tank or container I3. A pluralityof refrigerating tubes Il secured to a supporting element I5 is. positioned in the space between the sides of the containers III and I3. A shield IB secured to the container III, as at I1, covers the space between the containers.

container I3. During use of the cooler, cupies the space between the container A cover I8 is hinged, as at I9, on the Ill so as to close it andthe dry tank a cooling fluid ocsupport I5.` There is also provided a bracket 26, which has a main portion 21 provided witlLa circular opening 28 and a base portion 29 provided with openings 30. 'I'he main portion 21 has a groove 3l at its lower edge. The bracket 26 is attached to the outer side of the tank I3 by means of bolts or rivets 32 extending through the openings 30, at least some of `the rivets 32 being below the top of the support I5Xfor the coils I4. The portion 21 of the bracket 23 extends out over the support I5 in overlapping-.rel tionship with the portion 2| of the bracket 20, an a bolt 33 and nut 34 secure the brackets 20 and other. Similar brackets are provided at other points between the tank I3 and the. container I0. These brackets with their bolt and nut connections serve to hold the tank I3within the container I0 against'the buoyant force of the cooling iiuid in the space between the tank I3 and the container III.

When it is desired to remove the tank I3 from the container I0 for any reason, the cover I8 is opened, the shield I6 is removed, and the bolt and nut connections are removed from thel0 and 55 buoyant force of the cooling medium. 'The simple to one anpositioned between the containers and extendina to a point near the open end of the containers, the combination therewith oi.' means for holding the second container within the mst container against the buoyant force oi the cooling duid. said means comprising a bracket secured to the inside of the first container adjacent its open end alongside the device and extending up over the device toward the second container, a second bracket secured to the outside o! the second container adjacent its open end and extending toward the nrst container up over the device toward thenrst container in overlapping relationship with the i'irst bracket, and a member passing through the overlapping portions oi the brackets.

2. The combination specified in claim 1, the second bracket having a groove on its under side by means of which the securement of lifting means to the second bracket for removal oi the second container from the first container is facilitated.
