CONTAINER Filed April 17; 1959 12v VENTOR ARCH/E M M-fC'L/QEY HAS ATTORNEY Patented Sept. 30, 1941 UNITED STATES PATENT OFFICE comma Archie W. McClary, Oakland, Calif. Application April 17, 1939, Serial No. 268,203 "6 Claims. (01. 220-73) My. invention relates generally to containers and more specifically to metal drums or barrels particularly adapted for the'handling. of fluids such as oil or gasoline.

In the'handling storage and shipment of inflammable volatile fluids such as oil and gasoline it is important that the container used should not only be strong and durable in construction so as to withstand hard usage but that it should be of light weightand so constructed that no leakage of the contents will occur at the juncture of the walls particularly when the walls are subjected to deformation and damage through rough handling.

It is, therefore, an important object of my in- .vention to provide a light weight container that will stand up under rough usage with minimum danger of leakage.

Another object f my invention is toprovide a metallic container wherein the edges of the chime folds are-fused together to prevent leakage therebetween. r A further object of my invention is the provision of a light weight metallic container employing a reinforcing strip to which the edges of the chime folds are welded. l

Still another object of my invention is the provision of a metallic container wherein the edges of the chime folds are welded to a reinforcing strip in such manner that the closure sheet for the ends of the container may be readily severed for removal and welded together upon replacement.

Another object of my invention is the provision of a metallic drum employing an external strip or ring of metal highly resistant to deformation and to which the chime folds are fused.

The invention-possesses numerous additional objects and features of advantage, some of which, together with the foregoing, will become apparent upon perusal of the following description of my invention. It is to be understood, however, that I do not limit myself to this disclosure of the species of my invention as I may adopt variant embodiments thereof within the scope of the claims.

Referring to the drawing:

Figure 1 is a fragmentary view in perspective of a cross-section taken through one comer of a container embodying my invention but with the parts separated and unwelded to clearly lar body sheet of relatively thin metal which at its. top is peripherally folded outwardly and downwardly to provide a channel. A reinforcing ring or strip is provided to seat in said channel and is preferably of greater width than the depth of said channel so as to project beyond the end of the fold. A cover sheet formed of similar material t that of the bodyis provided and is folded upwardly, outwardly and downwardly to provide a-recessed shoulder adapted to, closely seat over the folds of the body sheet and form an end closure for the container. The folds of the sheets are then fused to each other and to the reinforcing ring thus permanently joining:

damage to the chime I provide a capping ring which fits over the-top of the chime.

In greater detail, the structure of my invention as illustrated in 'the drawing comprises a relatively thin tubular body sheet 4 of steel or other fusible metal alloy which is. folded outwardly and downwardly in the manner shown in the drawing to provide a marginal flange 6 having a continuous channel 1 adapted to snugly receive a ring or strip 8. This ring I prefer to form of a fusible metal alloy possessing high tensile strength so as to resist deformation and serve as a reinforcement for the rim or chime of the container.

In order to close the end of the container I provide a cover sheet 9 formed 01' material simia marginal shoulder H having a continuous recess l2 therein complementary to and within which the flange 6 of the body sheet is adapted to fit. The juxtaposed edges of the shoulder. flange and rim are integrally fused together as indicated by the numeral IS in Figures 2 and 3, either by resistance or metallic arc welding thus permanently sealing the space between the folds of the fiange and shoulder to prevent leakage therebetween and providing a rim or chime of.

great strength and durability. The folds which form the chime or rim of the container further provide with the ring a. reinforced bearing surface upon which the drum may rest or be suppo ted during trans ortation or storage. Such terminate above the outer edge of the flange in order to facilitate fusing of the parts by means of resistance welding. 1

While the structure thus far described is highly satisfactory, I have found it advantageous to protect the chime by providing a removable capping ring ll therefor which is designed to further strengthen the same as well as to prevent direct damage thereto in the event the container is subaas'mer disposed within an open end of said body formed of a sheet of said similar material and folded outwardly to overlap and substantially enclose the fold of said body, and said body and closure folds being integrally fused together and to said strip along a region longitudinally spaced from the marginal edge of said tubular body.

3. Acontainer comprising an open-ended tubular body formed of a sheet of fusible material folded outwardly and downwardly along a marginal edge to provide a continuous chann'elwhich jected to a blow or is dropped on a sharp edged or cornered object. I p

In practice the interior surface of the container is ordinarily provided with a galvanized,- enameled or other well known type of protective coating. Injury to such coating is to beavoided and by my invention this is accomplished for it will be observed that the fusion of the folds and rim takes place a substantial distance from the interior surface of the container which is, thereand having an annular recess formed on the infore, not affected by the heat generated during the welding operation.

I wish to point out a further'advantageous fea+ ture of my'invention. In this connection it will be observed that the folds of the chime are fused is substantially rectangular in cross-sectional contour, a strip of similar material snugly disp'osed in'said contour, a closure disposed within 15 an open end of said body'and formed of. a sheet of said similar material and having 'itsedge folded to overlap the fold of said body'with the edge thereof terminating adjacentthe edge of said body fold, and said 'foldsbeing integrally fused together and to said strip along a region longi 1 tudinally spaced from the marginal edge of said tubular body. Q 4. A container ner face thereof,-a closure disposed within an open end of said body-formed-of a sheet of saidsimilarmate'rial and folded to overlie the fold of said body,andsaidbody and closure sheets beonly along their lower edges; therefore, if the outer fold of the chime is sawed or otherwise out a through above the point of fusion, the cover sheet may be lifted ofl the container body to permit of resurfacing or cleaning of the interior thereof and thereafter such sheet may be replaced and the severed edges of the fold readily welded together. It is, therefore, obvious that my invention lends itself to the simple and economical repair of the damaged interior ofcontainers and has thereby solved a costly and diiflcult problem in the trade.

In Figure 3 I have shown a modified form of my invention. Here. the reinforcing ring 8 is provided with a continuous depression I! in one side thereof while the adjacent folds of the body and cover sheets are correspondingly deformed as at Hi to rest therein; thus added strength is given to the chime and the folds are restrained from separating.

I claim: a

A container comprising an open-ended body sheet, a backing ring of substantially rectangular cross-section, surrounding said body sheet and a cover sheet engaging said body sheet at an open end thereof, each of said sheets having an edge thereof in relative juxtaposition and folded outwardly over said backing ring, and substantially enclosing the same on three sides, said sheets being homogeneously joined together and with said ring along said juxtaposed edges.

2.
