Q I o.

This invention-relates to ods of manufacturing same.

Heretofore several types of single walled con-. tainers have been produced. One especial problem in all singlewalled metal containers is' to, provide a bung opening'which isnot adapt- I ed to drain thecontainer completely, but which 1 I also does not interfere with rolling the' con-' tainer uponits outer-surface. :This problem is aggravated bythefact that the bung openings of a container must-be adapted to standrough usage, so that they usually must be reinforced in some manner. l

The general objects of the present invention are to provide an improved. single walled coni containers, enema-- ly to single walled 'metalliccontainersjand; meth-' Stanley, Akron; out,

Further objects of the invention are: to provide an inexpensive, readily practiced method of forming a container which is adapted to stand hfe I I The above and other objectswill be manifest from, the following specification, which is described with particular, reference to the acrough usage andstill have along serviceable Figure 1 is a vertical sectional elevation of a container constructed in accordance with the invention; a

Figures 4 and 5 are enlarged fragmentary sectional elevations showing the edge of the reinforcing plate before it is secured to the container. v

Referring in detail to the accompanying drawing, a container i0 is shown, which container is made from end sections II and i2 which are secured by butt joints to a medial container section or ring l3 which has spaced rolling rings l4 and [5 formed thereon. The rolling rings i4 and' I5 are formed in an enlarged rolling band contents'fcfthe container.

The domeor deepest point of the head, I la is formed in 'a portion' thereof opposite 'toth'e tapping liner l'l whereby all of the contents" or the; container can be removed therefrom A strengthening-and reinforcing double walled chime 20 also is formed in tion'ilf I I A bungopening 2| is formed: in the'container ring it, which opening is definedjaya bung liner 1' 22 which is formed integrally with-a reinforcing lnasolne .case, the bung linen-22 .is l formed separatelyvand butt weldedto the plate I 23. This reinforcing plate ziris'ffornied with, a predetermined contour so that the'edges of plate 23.

, aid in draining the containerf ompietely ,when

thebung opening is placed "at'the lowermostside thereof." Thereinforcing plate 23 is positioned in the container] ID by atomic welding, by which method the remaining Joints of the container also are made. This method comprises fusing pieces of metal together by the heat set up by an elec-- tric are directed upon the metal parts to. be

it that is formed in the container ring l3, which band is continuous and may be formed by rolling-it into the container ring it. Both of the I container sections ii and I2 have dome shaped heads Ho and He, respectively,'provided therefor and a tapping fitting is provided in the head Ila. This fitting may comprise a tap bushing or liner l'l, the outer edge of which is flush with the surface of thedome Ila. The liner .ll, extendslnwardly of the container and conunited and directing a stream of hydrogen against the surfaces as they are being fused together, whereby oxidation of the heated metal is prevented.

In the container shown, the reinforcing patch 23, which preferably i made from the same metal as the remainder of the container, has the bung liner 22 formed After this bung liner is formed, the radially outer edges 23a of the reinforcing plate are beveled off, or coined in any suitable manner to form a slightly curved surface. Then the thin I outer end of the plate is bent up upon itself' at 231) as shown in Figure 5 to, .aid' infusing the plate to the container. The reinforcing patch usuallyis formed to the. exact contour desired before the edges areprepared for being fused to integrally thereon.

the, container s ec tric arc is progressively directed upon the ,en-

, tire edge portion of the .plate. This electric are usually is set up by an atomic hydrole'njwelde asaam It will be appreciated thatthe foregoing desorlption of the invention is for illustrative purposes only and that the scope of the invention includes modifications thereof such as are covered by the appended claims.

What is claimed is:

1. In a single walled metallic container, a body -portion comprising end body sections of sub ing head which plays astream of hydrogen upon 7 the surfaces being subjected to the arc. turned up edge portion of the reinforcing plate .fh'r'nelted by the arc and secures the reinforcing plate in the container section II when it solidinee; Usually it is desirable to prevent oxidation of the outer surface of the container ring :lt. This can be done by clamping a metalplate (not shown) to the outer surface of'the container and providing anarrow groove in such plate that follows the contour of, and radially overlies, the edges'of thereinforcing'plate II.

'Hydrogen is introduced into and burnedin this groove as the I reinforcing plate is fused into :position to prevent an unsightly outer surface from being formed on the container..

Preferably, the container of the invention is m'adefrom stainless steel material which is cold .worked to thefinal shape desired, whereby the material is strengthened. A reinforcing sput 25 may be provided on the other surface of'the bung liner 22 to reinforce same. Note that the outer end of the bung liner 22 ispressedoutwardly and downwardly against the sput 25 and may be welded to the adjacent surfacesof the container ring I! to form. a permanent water- 'tight seal between the bung opening and the container. Before securing the outer end of the bung linergin this manner, it is advisable to test the weld formed at the edges of the reinforcing plate 23 to determine whether or not it not interfere with rolling the container on its side and the'container is provided with a reinforced bung opening which permits the con tainer to be completely drained.

stantial axial length, an intermediate body section Joining said end sections in welded relation, said end sections having re-entrant dome shaped container head portions, said intermediate body section being in the form of a continuous band having a radially outwardly extending middle portion of substantial width, said middle portion having a cylindrical re-entrant portion of substantial width formed with spaced rolling rings at its edges, said cylindrical reentrant portion having a bung aperture formed therein, said container having a. reinforcing plate attached to the inner surface of said intermediate section by means of a fluid tight weld at the outer edge of said plate, said plate being bridged over the bung aperture in said reentrant portions, said plate having abung aperture formedtherein and a bung liner traversing the space between said apertures. said liner being attached at its opposite ends to said plate and to said cylindrical re-entrant portion respectively.

2. In a single walled metallic container, end sections ofsubstantial axial length formed with chimes, and an intermediate section, said intermediate section having a radially outwardly extending middle portion, the edges of said portion extending radially outwardly a further distance forming spaced smooth rolling surfaces for the container, said intermediate section having a bung aperture formed in said enlarged central portion, a reinforcing plate having its edge portion welded to the inner surface of said enlarged portion, the central portion of said plate being bridged over the bung aperture in said enlarged central portion, said plate having a bung aperture formed therein and a bung liner traversing the space between said apertures and being attached to said plate and to said enlarged central portion.
