Referring to the drawings, and

larlyto Figures 1 to 4, inclusive,

more particuit will bes'een of the shells.

The inner shell S is made upof two tub-like sections designated at l and 2, the edges of the body portions of thaopen ends of which are brought into abutting relation and welded together asat 3. Preferably, the

closedends or heads 4 of the sections- -of the inner shell are dished or crowned as shown in the drawings.

The jacket orfouter shellJ, is also made up of apair of tub-like sections designated at 5 and 6 which surround the sections of the inner shell in the assembly although disposed 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 and these curls are brought into indicated at 1 abutting relati'on and welded together as at 8. In this respect the container of the present invention 'embodies features described and claimed in my application for Metal barrel, filed No Serial No. 696,755.

vernber 6, 1933,

1934, Serial No. 748, 31 9." A tap" bushing designated generallyat I2 is provided in the top of the barrel and is of conven; integrally formed therewith outwardly directed corrugations above and below the bung bushtional construction, although combined with th e inner and outer shells .of the barrel ina*-n'ovel manner.

and 2, the tap bushing 12 is a forging and-its peripheral portion at its lower or inner end is,

Iwelded to the upper head 4 offitheinner shell as indicated at W. Prior to welding the'tapbush ing to the inner shell a protective ring or :annulus of;

metal I! is slipped over the bushing and held up against thelugs '12" thereof by tack welding or in any other 'suitableinanner. After the weld W has-been formed the ring IT-is released-from the lugs I2 and drops down to the position shown in the drawings. 'Its purpose is to protect the Weld W during the "formation of the'weldl8 which 'unitesth emar'gino'f the tap' opening in the outer head'l 0 to the tap bushing intermediate its ends. In forming the weld l8 sufficient metal isfsupplied to fill in the opening in-the head of theouter shell orjacket J. p

A bung bushing 16 which may also bea metal forging is provided between the inner and outer shells and is welded to the innershell as indicated at I6 and the outer shell as indicated atHGP. The Weld l6 may be between the margin of an opening in the inner shelland a shouldered portion |6"'of the bushing I'G: Similarly, the weld W employed between the tap bushing and the inner shell may be between a portion of the inner shell whichabutsa recessed or'shouldered portion 13 of the tap bushing." It will be seen'from the foregoing that the tap buShi'ngI-Z' and bung bushing l6 mechanically interconnect the inner and outer shells at two points and'thereby tend to maintain'the same in proper spaced relation. In this action these bushings are aided by the insulations H andI. In-some instances; however, the inner shell shifts or tends to' shift with respect tothe 'outer shell and where shifting occurs stress is built up at thetwo points where the inner shell is secured to the outer shell, namely, in the region of 'th'e tap and bung bushings. This concentration of stress may result in fracturing either the welds or the inner shell at or near either one of these two points. Thereupon le'akageof the contents will take place between the 'inne'r and'oute'r shellsand the container is rendered unfit for use. if

The present invention proposes to preclude any such concentration of stres s'and consequent fracturing and leakage and accomplishes this by providing means whichcoacts with the bung and tap bushings to provide a three-point suspensionof the inner shell on the outer shell. In effecting this three point suspension a steel circular plate 20 which is of approximately the same gauge material as the inner shell is welded as at 2| to the exterior of thelowerend head 4 oppositethe low point L'of the inner shell.' A hole 22 which may be approximately one-inch i'n diameter is punched or drilled in the outer shell in such position that it will come directly under the plate 20 when theashells are assembled. After the weld 8 has been formed the portion of the In the structure shown ins-Figures, 1...; o o

' aroundpthe, ;barr el:and provide rolling hoops -.which improvethe handling of the barrel in that ;they make it possible to roll the barrel in a straight line without the use of skids. The hoops outer shell which surrounds the opening 22 is then welded as at 23 to the plate 20. This welding may be just simply a bead between the margin of the opening 22 and the plate 20 or the hole 22 may be entirely filled up by supplying additional metal during the welding operation.

With this construction the inner shell is supported on the outer shell at three points and in such manner that relative shifting and concentration of stress is avoided. ;In addition to the foregoing, the outer shell has ing. l6.. .-These corrugations extend entirely Vinvention'and to' realize certain other purposes may be varied, although in all instances it is usually desirable to have these bushings not only serve'their purposes in'co'nnection with the cleaning'and filling and dispensing of the contents but also to mechanically function in maintaining the inner and'outer'shells in proper position relative toeach other," Thus, as illustrated in Figures 5 and 6; the tap bushing-there designated at which is substantially similar to the tap bushing 12 and of conventional construction in its main features, may be recessed orcutaway as at 3| to permit of the hanging up of the portion 32 of the upper end head 4 of the inner shell S, as illustrated in Figure 5. The portion 32, which is the marginal portion of the opening provided in the upper head 4 for the tap bushing, is then welded tothe tap bushing'as indicated at 33. The outer peripheryof the'inner end of the bushing is also welded to the upper end head 4 of the inner shell as indicated at'33. As in the other embodiment of the invention, a protective ring or annulus of metal designated at IT is provided in order to protect the weld 33" during the formation of the weld l8 between the portion H! of the upper end head of the outer shell or jacket J and the intermediate portion of the bushing 30.

A somewhat similar though specifically different means is provided for organizing the bung bushing, shownin Figures 7 to 9 and designated at 40 with the inner and outer shells of the barrell Thebushing' lllis conventional in its construction except for the provision of a recess 41 toreceive a flanged up portion 42 of the inner shell; Portion 42 is welded as at 42 to the bushing 40. The bushing 40 also has its outer periphery at its inner end welded to the inner shell as indicated at 43 The outer end portion of the bushing is received'in an opening in the outer shell or jacket J, which opening is designated at 44 and indicated in dotted'linesinFigure 9. The portion of the outer shell surrounding the outer end of the bushing is displaced inwardly slightly and then welded to the'bushing as indicated at 45. After'the welds are formed they are smoothed down in a suitableman'ner so as to leave a smooth flush surface.

WhileI have shown and described several constructions in which the invention may be advantageously embodied, it is to be understood that these constructions have 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 without departing from the spirit of the invention or the scope of the subjoined claims.

The invention claimed is:

1. A container of the character described comprising inner and outer shells, the inner and outer shells being made up of tub-like sections welded together in the assembly, a tap bushing welded to the upper end heads of the inner and outer shells, a hung bushing weldedto the body portions of the inner and router shells, a plate welded to the lower end head of the inner shell in vertical alinement with the tap bushing, the lower end head of the outer shell having an opening underlying said plate and a Weld between the margin of the opening and said plate.

2. A metal container of the character described comprising inner and outer shells, means for securing the shells in spaced relation and an auxiliary support and connection between the shells comprising a plate welded to the inner shell,

the outer shell having an opening overlying the 10 plate, and a weld between the margin of said opening and said plate.
