LAMINATED METAL BARREL Filed Jan. 14, 1953 Ell Patented June 9, 1936 UNITED STATES PATENT OFFICE Stewart S. Battles, Chicago, Ill., assignor, by mesne assignments, to Borg-Warner Corporation, Chicago, 11]., a corporation of Illinois Application January 14, 1933, Serial No. 651,716

6 Claims.

This invention relates to metal containers and will be described as incorporated in a barrel formed of composite metal.

An object of this invention is the provision of a metal barrel formed of sheet material, the sheet metal including an inwardly disposed lamination of non-corrodible material, preferably an alloy for resisting possible chemical actions of the contents of the barrel on the inner surface, and a lamination of other metal preferably a mild steel disposed outwardly.

Another object is the provision of a barrel having a portion formed of two composite sheets of metal each including a non-corrodible portion,

' such that the completed barrel will have no corrodible' portions disposed inwardly and such that the sheets forming the barrel will be welded together by. adeposit of metal on the inside of the barrel without causing an appreciable irregularity on the inner surface of the barrel.

The metal employed-in the construction of barrels in accordance with this invention is preferably of the kind, and made by the process set forth in United States Letters Patent No. 1,868,749 issued July 26, 1932 to Stephen L. Ingersoll, to which'reference is hereby made for a detailed description of the metal and process of forming the composite sheets.

Other objects and advantages of this invention will become apparent from the following detail description with reference to the accompanying drawing.

(in the drawing:

Figure 1 is an elevatlonal view of a barrel incorporating my invention, a portion of the same being shown in section to better disclose the construetlon of the same.

Figure 2 is an enlarged fragmentary section taken on the line 11-11 of Figure 1.

Figure 3 is a section similar to Figure 2 but illustrating a modified form of construction, and

Figure 4 is an enlarged section similar to Figure 2 but illustrating a further modification of the invention.

As shown on the drawing:

The barrel 5 preferably comprises end or base portions 6 and l and a container portion ll. The container portion is preferably formed of two deformed sheets 9 and ii! of metal. Each sheet and it was preferably formed from a single ably consisting of stainless steel or other now corrodible chromium steel alloy. The two laminations are intimately welded together throughout their engaging areas forming a single sheet of composite metal. The term composite as used in this specification and in the claims has reference to this specific type of sheet metal construction as set forth in the above mentioned patent to'Stephen L. Ingersoll. The marginal portions of the sheets 9 and ID are flared outwardly at l3 and M to provide an annular space which is preferably filled with a deposit of stainless steel as indicated at to form a permanent weld for securing the flared portions I3 and I4 together in alignment and with the inner surface of the deposited metal forming the weld, being in substantial alignment with the inner surface of the barrel to avoid appreciable irregularities and crevices into which the contents of the barrel might gain access and make cleaning diflicult.

The edge portions l1 and I8 of the sheets 9 and in are permanently interlocked, to relieve excessive strain at the welded joint, and to provide an annular reinforcement around the central portion of the barrel. In the form of the invention shown in Figure 3, the edge portions of the flared margins are rolled together instead of being folded together as shown in Figure 2, thereby forming a relatively rigid annular roll 2| extending around the barrel and interlocking the sheets 9 and I0 together. In the modification shown in Figure 4, the flared margins l3 and M are very short and the outwardly disposed edges are permanently welded together by an annular deposit 22 of metal. In this modification, the exterior weld 22 is preferably of a tough mild steel, whereas the inner weld i5 is a suitable corrosion-resisting allow or stainless steel.

Referring now to Figure 1, there are provided annular corrugations 26 and 21 for reinforcing the sheet metal of which the barrel is composed, in order that the barrel may be as light as possible and sufiiciently rigid to withstand rough handling and rolling when filled. One end of the barrel is provided with an opening 28 through which thebarrel may be filled with beverages such as beer and the like. The ends of the barrel 3i and 32 are preferably dome-shaped and side portions of the barrel, thus avoiding all sharp corners and recesses which would be difficult to clean. The end or base portions 6 and l are preferably substantially cylindrical, fitting upon the ends of the container portion and beare substantially arcuate where they join the r ing permanently welded in position as indicated at 33 and 34. The extreme end edges of the base portion may be rolled as at 36 and 31 to reinforce the same and prevent bending when being handled.

The base portions 6 and I are provided with

corrugations

42 and 43 which engage the container portion adjacent the welds 33 and 34 re- 'spectively, and serve as a guide in positioning the base portions as well as to provide reinforcement to withstand shock and relieve the welds of undue stress It will be understood from the foregoing description that this invention is susceptible of various forms and modifications without departing from the principle of the same. I desire,

' therefore, that the patent to be granted hereon shall not be restricted in any manner, except as necessitated by the prior art.

I claim as my invention:

1. A metal container comprising a pair of superimposed tub-like members having continuous inside surfaces of a corrosion resistant alloy backed by an outside integral lamination of tough metal. bonded thereto at all points, outwardly flanged abutting edges around the peripheryof said tub-like members defining a groove between the tubs, a. weld of corrosion resistant alloy in said groove joining the tubs together and additional reinforcing structure cooperating with the outside of said tubs for holding the tubs in assembled relation.

2. A metal container comprising ,a pair of superimposed tub members having continuous inside surfaces of stainless steel backed by an integral layer of mild steel bonded thereto at all points, outwardly flanged abutting edges around the peripheries of each of said tub members defining a groove between the tubs, a weld of stainless steel in said groove joining the tubs together and an outside weld of mild steel between the abutting edges of the tubs for reinforcing the inside weld.

3. A barrel including complemental composite sheet metal tub sections having an interior surface of non-corrosive metal and an exterior surbonding said tub sections together comprising a welding body of non-corrosive metal filling such groove fiushly with the interior of said barrel, and additional bonding means exteriorly of said barrel and in registry with such groove.

4. A barrel comprising complemental composite sheet metal tub sections having an interior surface of non-corrosive metal and an exterior surface of a different metal, said sections having opposed contiguous peripheral flanges turned outwardly thereby effecting an internal annular groove circumscribing said barrel, means for bonding said tub sections together comprising a welding body of non-corrosive metal filling such groove fiushly with the interior of said barrel, and additional structure augmenting the bond of said welding body, said structure comprising said flanges disposed in an interlocking relation exteriorly of said barrel.

5. A barrel comprising complemental composite sheet metal tub sections having an interior surface of non-corrosive metal and an exterior surface of a different metal, said sections having opposed contiguous peripheral flanges turned outwardly thereby efiecting an internal annular groove circumscribing said barrel, means for bonding said tub sections together comprising a welding body of non-corrosive metal filling such groove fiushly with the interior of said barrel, and additional structure augmenting the bond of said welding body, said structure comprising a reinforcing loop substantially circular in cross section and formed of said flanges disposed in an interlocking relation exteriorly of said barrel.

6. A barrel comprising complemental composite sheet metal tub sections having an interior surface of non-corrosive metal and an exterior surface of a different metal, said sections having opposed contiguous peripheral flanges turned outwardly thereby efiecting an internal annular groove circumscribing said barrel, means for bonding said tub sections together comprising a welding body of non-corrosive metal filling such groove fiushly with the interior of said barrel, and additional structure augmenting the bond of said -welding body, said structure comprising a reinforcing band fiat in cross section and formed of said flanges disposed in an interlocking relation exteriorly of said barrel.
