METAL CONTAINER Filed Oct. 15, 1954 2 Sheets-Sheet 2 Patented Oct. 4, 1938 UNETED STATE LISF PATENT 1- OFFICE MET L CONTAINER. I William E,; CoakleyQMilwaukee; assignor to Pressed Steel Tank (lompany, Milwaukee, Wis v a corporation of Wisconsin I I Application Octoberl5, 1934, Serial No. 748,319 7 ICIaim. (01220- 'iYjj- This invention relates to 'an improvement; in containers and more-particularly tolimprov'ements in metal containers 'for beverages such as beer barrels or the like. i

One object of the invention is to. provide a receptacle of this character which is simple, compact and well balanced in construction, rugged and durable in use, and so constituted as to minimize exchange of heat between the contents of thecontainer and the exterior.

Another object of the invention is to so construct and organize a receptacle of this character as to provide for permanent, effective and satisfactory interconnection of the bung and tap bushings therewith and this in such manner as to avoid any internal crevices or ridges which tend to preclude effective and expeditious cleans- .ing of the interior of the receptacle.

Still another object of the invention is to provide a container of this character which may be readily and economically produced in quantity' and by the use of facilities and practices consistent with production on a commercial scale.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings, forming a part of this specification, and in which:

Figure l is a view partly in transverse vertical section and partly in side elevation showing a metal container embodying the present invention;

Figure 2 is a view-in vertical section on an enlarged scale illustrating how the tap bushing is organized and interconnected with the elements of the container head;

Figure 3 is a fragmentary View in section taken on line 3-3 of Figure 2, parts being shown in elevation for the sake of illustration;

Figure 4 is a fragmentary View in vertical cross section illustrating the manner in which the bung bushing is organized with the elements of the container;

. ure 5 but showing different parts broken away.

Referring to the drawings, it will be seen that V the container or barrel providing the present invention comprises generally an inner shell S and of the shells.

an outer shellor jacket designated at'J with interposed insulation I between thebody portions of the shells and insulation H between the heads *Theinner'shell S is made up of two tub-like sectionsdesignated at l and 2, the edges of the body portions of theopen ends of which are broughtinto abutting relation and welded together as at 3. Preferably, the closed ends or headsl i of the sections of 'theinn-er shell are dished or crowned as shownin the drawings;

The jacket or outer shell J is also made up of a pair of tub-like sections designated at 5 and 6 which surround the sections of the inner shell in the assembly although in spaced relation thereto. The edges of the open ends of the body portions of the sections 5 and 6 of the outer shell are bent back or curled as indicated at l and these curls are brought into abutting relation and welded together as at 8. The closed ends of the sec tions of the outer shell or jacket are cupped as indicated at 9 in order to provide the chime structures of the barrel.

All portionsof the closed ends of the sections of the jacket including the portions ID are spaced from the adjacent portions of the ends of the inner shell. The portions H] are dished or crowned in substantially the same way as the ends 4 of the inner shell and in between these portions the sheet-like layers or laminations of insulation H are interposed. These layers H are preferably made up of heavy sheets of paper impregnated with asphalt and function not only as insulation but also aid in the mechanical support or suspension of the inner shell in proper relation to the outer shell. The latter function follows from the fact that the sheets H are substantially non-compressible and are tightly packed in and completely fill the space between the heads 4 and I0. Because of the additional space between the body portions of the shell the insulation I is preferably a suitable type of wool.

By having the curls l spaced from the inner shell they exercise their reinforcing action and aid in taking shocks and blows without transmitting them to the inner shell and this feature also cuts down interchangeof heat between the barrel contents and the exterior.

A tap bushing i2 is provided in the top of the barrel and is itself of conventional construction except that it is recessed or cut away as at 13 to permit of theflanging up of the portion [4 of the upper end head 4 of the inner shell S, as illustrated in Figure 2. This portion [4, which is the marginal portion of the opening provided in the upper head 4 for the tap bushing, is then welded to the tap bushing as indicated at 15. The outer periphery of the bushing is also welded to the upper end head 4 as indicated at l6. Prior to welding the bushing l2 to the inner shell, a protective ring or annulus of metal designated at I! is slipped up over the bushing and held up against the lugs l2 thereof by tack Welding or in any other suitable way. I After the welding at [5 and I6 is completed the ring I1 is released from the lugs 12 and drops down to the position shown in the drawings. Its purpose is to protect the weld [6 during the formation of the weld l8 which units the margin of the tap opening in the outer head 0 to the tap bushing. In forming the weld l8 sufiicient metal is supplied to fill in the opening in the head of the outer shell or jacket J.

A somewhat similar though specifically different means is provided for organizing the bung bushing 20 with the sections or shells of the barrel. This bushing 20 is conventional in its construction except for the provision of a recess 2i to receive a flanged up portion 22 of the sections of the inner shell. A weld 26 is provided between the portion 22 and the bushing 20. The bushing 20 also has its outer periphery portion at its inner end welded to the inner shell as indicated at IS. The outer end portionv of the bushing 20 is received in an opening 24 provided therefor in the jacket or outer outer shell J. The portion of the outer shell surrounding the bushing is displaced inwardly slightly and then welded to the bushing, as indicated at 25. After the welds are formed they are smoothed down in any suitable way so as to leave a smooth flush surface.

While I have shown and described one construction in which the invention may be advantageously embodied, it is to be understod that this construction has been selected merely for the purpose of illustration or example and that-various changes in the size, shape and arrangement of the parts may be made as will be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the subjoined claim.

The invention claimed is:

A container of the character described comprising inner and outer shells having body portions and end heads, insulation between the body portion of the shells, and combined insulation and supports interposed between the end heads of the shells and comprising a plurality of laminations tightly packed between the end heads and completely filling the space therebetween, said laminations consisting of a plurality of sheets of paper impregnated with asphalt, said tightly packed laminations being substantially non-compressible to function as eflective mechanical supports.
