(c1. 22o-1o) My invention relates to barrels and particularly to an all-metal barrel of double wall construction wherein the outer reinforcing portion supports the inner liquid container portion..

- In the co-pending applications of Charles H. Widman, Serial No. 670,663 led May 12, 1933, and assigned to the assignee of the present invention, a liquid tight all-metal barrel'was illustrated, described and claimed wherein the inner vcontainerA portion formed a unit which was strengthened and reinforced by capl elements which were supported thereon.

In practicing my invention,`I employ the inner liquid container portion as described and claimed in the above mentioned co-pending applications and entirely encompasses the portion in an outer reinforcingshell which is of heavy gauge material 'and which is self-contained, forming' a complete unit which is secured to the inner liquid 2o container portion in such manner as to be a support therefor. In this type of construction the outer reinforcing shell is the support for the inner liquid container portion. The-inner liquid 'container portion may be made of light gauge material since the heavy reinforcing portion provides protection for the inner liquid centaine portion.

' y Accordingly, the main objects `of ,my invention are: to provide aliquid tight barrel wherein an inner liquid container portion is supported andreinforced by a heavier outer encompassing portion: to provide end reinforcing members for the liquid container portion which contacts the liquid container portion at the bilge to form a support therefor; to span the two reinforcing cap portions by a strong metal band which unites the cap portions to form a unit which protects the y inner liquid-container portion; to provide a bung for the barrel which has shouldered portions for receiving the metal of the containing and reinforcing portions of the barrel which is thereafter flanged over and brazed, soldered, welded.

or otherwise secured to the metal in a liquid-V tight manner; to provide a bung at the bilge of the barrel which is flush with the bilge and which is provided with serrations forming.

grooves into which the wood of the bung may swell upon being soaked with the contained liquid to tightly engage the grooves and lock the bung against the pressure of the liquid developedwithin the liquid container portion; to reinforce the chime or handhold portions of the barrel by annular preformed portions or arcuate preformed portions as the case may be; and, in general, to provide an all-metal barrel having inner and outer metal unit portions which is simple in construction and economical of manufacture.

Other objects and features of-novelty of my invention will be either specifically pointed out or will become apparent when referring, for a bet- 5 ter understanding of my invention, to the following description taken in conjunction with the accompanying drawing, wherein;

Figure 1 is a view, in elevation, of a barrel of the tight type embodying features of my lnven- 10 tion,

Fig. 2 is an enlarged sectional view of the structure illustrated in Fig. l, taken on the line 2--2 thereof, A

Fig. 3 is an enlarged sectional. view o'f. the 15 structure' illustrated in Fig. 1, taken on the line 3-3 thereof,

Fig. 4 is a plan view of the barrel illustrated in Fig. l, and

.Fig'. 5 is an exploded plan view of structure zo similar to that illustrated in Fig. 3, showing a modied form thereof.

Like the barrels in the above mentioned co': pending applications, the inner container ofv the present barrel is made up of like -pressed metal 25 elements II'. The elements are preferably provided with an outwardly directed flange I2 which abut together to form a joint, which is readily welded, preferably through the melting of the anges I2. The inner container thus formed is 30 made of comparatively light gauge material in view of the fact that it is entirely protected by the outer reinforcing portion I3 of the barrel. 'Ihis portion is made up ofl two like pressed metal elements Il which are press fitted over the 35 inner liquid container portion II, being joined thereto, at the bilge, by the flanges I5. The flanges form a support for the inner liquid container portion. The reinforcing portions Il are similar in construction to that of the above men- 40 tioned-co-pending application having step Vportions I6 which add strength to the barrel and a' web portion I'I in combination with an annular flange ,portion I8 which forms a surface upon which the barrel may be rolled on tracks or 45 across a'at floor. Chimes I9 are provided on both ends of the barrel to form handhelds and stacking ends which are herein shown as being reinforced by annular, arcuately shaped elements 2|. f 50 After the reinforcing' end caps I4 have been spot welded to the inner liquid container portions II and the portions are welded together, a

bilge band 22 is applied over the annular flange portion I8, having side ledges which are like arc- 55 uately shaped to encompass the flanges I8 and are abutted together at the bilge bung 24 of -the barrel. The band is welded to each section, at 25, to form a unit construction with the two reinforcing elements I4. The outer reinforcing portions I4 and the belt 22 are made of heavier material than the inner liquid containing portion II and thereby support, and protect the inner portion from damage.

The bung 24 comprises an annular portion 26 having a top flange 21, the former of which extends through the belt 22 to engage an inner flange 28 on the inner liquid containing portions I I to be brazed, welded, or otherwise secured thereto in a liquid-tight manner. The outer flange 21 of the bung 24 is welded directly to the belt 22 at the time the belt is Welded t0- gether. The bung is provided with a plurality of grooves 29 which form lands on the inner cylindrical or frusto conical surface of the bung, for the purpose of having the wood plug expand when saturated with the liquid contained in the barrel, to be forced within the grooves to thereby form the tight engagement to prevent the pressure, which may be developed by the liquid within the barrel, from forcing the plug from the bung.

At the top of the barrel, the inner liquid container portion II and the reinforcing portion I4 are joined by a bung 3I which is provided with shoulder portions 32 for receiving the ends of the metal about apertures in the portions. E The edges of the bung are then penned or flanged over at 33 to form an anchor between the bung and the metal and a brazing solder'may be employed additionally for sealing the bung to the metal. It is to be understood that the bung is secured to the inner container portion II first and thereafter secured to the outer reinforcing portion I4 of the barrel. While the inner cylindrical surface of the bung may be left smooth, or corrugated as above described, I have illustrated a thread provided thereon to which a. standard iitting may be secured.

It is to be understood that insulating material 30 as described in the latter of the above mentioned co-pending applications, may be provided between the inner and outer shell portions of the barrel and between the inner portion of the barrel and the belt 22 for the purpose of substantially insulating the barrel.v When such insulation material is not employed, the air trapped between theinner and outer portion of the barrel will provide insulation to a satisfactory degree.

Referring to Fig. 5, I have illustrated a modified form of construction wherein the chimereinforcing element 2l is made up of three arcuate sections 35, each being 120 degrees in length and having the cross section as illustrated in Fig. 2. The three sections are then welded to the barrel and to each other to form a complete reinforcing annular support. 'I'he advantage of constructing the reinforcing element 2l in sections is to eliminate the waste of metal which would occur if the reinforcing element were stamped in asingle piece. By stamping them in sections, as illustrated in Fig. 5, substantially no waste of material results.

While I have described and illustrated'several embodiments of my invention, it will be apparent to those skilled in the art that various changes, omissions, additions, and substitutions may be made therein without departing from the spirit and scope of my invention, as set forth in the accompanying claims.

I claim as my invention:
