METALLIC CONTAINER.

Application filed July 2,

tainers generally, is more particularly concerned with the construction ofbarrels or drums used in shipping of liquids, or, tanks of cars employed 1n transportation of'gasolene, fuel oils and the like.

Containers of the type specifically men tioned are usually constructed of relatively stout sheet metal in contradistinct-ion to thicknesses thereof more commonly known as tin with the ends of their body portions turned over the edges of the closure heads to retain the latter in place, the latter operation entailing sharp bending of the metaloften to the extent of'causing crystalliza-, tion-at the. regions of juncture, which, under vibration induced through surging of the contents of the containers in transit" are liable to become fractured so that leakage ensues. This contingency not only entails the loss of the container contents, but, in the case of lubricating oils, fuel oils, etc.,

i is attended by dangers of fire hazard.

M I invention is directed toward structuraiiy improving containers of this class such as will insure increased .rigidity and stu-r'diness against abuse in handling as well as against surging of the contents both with regard to deformation, and the possibility.

of fracture or opening of the-joints between the component parts.

One wa in which this desideratumfmay be'realize will be readily apparent from the detailed descri t-ionhe'reinafter of atypical embodiment o my invention,-the appended claims serving a) define those features which 7 I believe to be entirely novel over container constructions heretofore known. l With reference to the drawings, Fig. I isan'elevational view of a container made in accordance with my invention.

into rounded perimetric or circumferential terminal heads 2 of substantiall semi-circular cross section as shown in Fig. II, said beads merging with adjoining perimetric or circumferential depressions or recesses 3 that not only function-to strengthen the cylinder against deformation, but provide continuous internal shoulders useful for a purpose hereinafter explained. The beaded ends 2 are preferably made of the-same diameteras the intermediate part of the body portion 1, so as to be externally flush with the same to the avoidance of any surface projections. The ends of the body portion ,1 are closed convenient manner-into conformity "with,

and to overlap the peripheral beads 5 of the heads 4. The beads 5 of the head's' t thus determine the extent to which the ends of the body portion 1 are rounded, so that fractural or prohibitive bending is entirely obviated and the possibility of failure ofthe metal under continuous vibration (whereto barrels in transit. or vehicle tanks are at all by circular heads 4 also made of sheet metal,

fluid tightness is desired-or required, the,

overlapping beads 2 of the body portion 1 may be permanently joinedto the beads 5' of the heads 4 by edge welding as indicated conventionally at 6 ln'Fig. II.

en the component parts of the container are assembled in the manner explained, it will be a parent that the heads 4 are braced against displacement inward by the internal shoulders 3 of the body portion 1; and that as a result of being welded together, the beads 2-5 are, in each instance, I

merged into one continuous well-rounded= composite orner edge of double thickness,

which, by virtue of the overlap, is amply reinforced at a region that must of necessity be capable of withstanding the severest strains in usage.

. While I have herein shown and described the container as being of cylindric cross section, it is to be understood that the improved structural characteristics of my invention may, as readily and with equal advantages, be embodied in elliptic or polygonal forms.

Having thus described my invention, I claim:

1. A container of sheet steel comprising a cylindrical body portion having an internal corrugation merging into a substantially semi-circular cross-section terminal head at each end thereof, similar material flat closure heads therefor having outset peripheral beads of half-round cross-section seating on the corrugations and overlapped by the terminal beads aforesaid, said overlapped portions forming a double thickness corner-edge whereby the container is rigidly braced against deformation with the heads securely prevented from inward or outvard displacement, and said terminal and peripheral )eads being joined by edge welding on the exterior surface for fluid tightness at the overlapped junctures.

2. The method of manufacturing a sheet metal container which consists in swedging a cylindrical shell adjacent its opposite ends to provide circumferential recesses, forming closure heads of sheet metal with peripheral stiffening beads of half-rounded cross section, insertine the heads with the beads projecting outwardly within the shell ends to abut the circumferential recesses, rolling the rojecting ends of the shell into conformity with and to overlap the peripheral beads of the closure heads, and welding the overlapped shell ends to the exterior surface of said heads to form a fluid-ti ht ioint.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 26th day of June, 1924.
