This invention relates to improvements in Fig. 8 is an elevation in central section probarrel fittings for bungs and is especially applicable to barrels made of sheet metal, and the object of the improvement is to construct and apply a hung ring to a sheet metal wall of a barrel so that it will be held from turning and so as to obviate leakage when the opening is closed by a bung; another object is to afiord a bung fitting that may be made and applied with greater economy than in the usual practice; and a further object is to construct and apply a bung ring to a barrel wall in a manner as will insure uniformity in its manufacture and efficiency. in the performance of its function.
Ordinarily, a bung ring is applied to the head or shell ofa metallic barrel by soldering it in the opening made therefor, or by riveting or welding its flange to the shell at the opening. These operations are not only expensive ut tortion of the bung ring to such an extent as to interfere with the introduction of the bung. Such practicealso necessitates testing of the completed job for detection of imperfections in the welding or other operations that would cause leaks. To overcome these defects is included as an object of the present invention.
The above objects are accomplished by the construction illustrated in the accompanying drawings, in which: I
Fig. l is a plan view of a hung fitting applied to the head or shell of a barrel which is shown in part, there being portions broken away;
Fig. 2 is an elevation, partly in central section, projected from Fig. 1;
Fig. 3 is a plan view of a portion of a metallic sheet that forms the head or shell of a barrel and shows a circular distention made therein at its first stage of formation;
Fig. 4 is a plan View of the distention in its second stage of formation;
Fig. 5 is a central section projected from Fig. 3;
Fig. 6 is a central section projected from Fig. l- Figf'? is a bottom plan View of the distention in its third stage of formation;
frequently result in the disjected from Fig. 7; and
Fig. 9 is a central section of the distention in another stage of formation, a hung ring being included in the View.
In the drawings, 1 is a bung'ring having at one end thereof a polygonal flange 2 that projects radially, the ring being. internally threaded so as to receive the bung 3 when screwed therein. The bung is preferably of the ordinary type having a flange 4 and fitted with a gasket 5 adjacent its flange. 6 indicates the container head formed from sheet metal of suitable gage.
An especial feature of the invention is the manner of securing the ring in place upon one surface of the sheet metal wall, of which the head or shell ofthe container or barrel is constructed, and adjacent and surrounding the opening therein.
The sheet is first prepared by shaping a cir' cular distention 7 concentric with an opening 8 so that a cavity 9 is formed in the sheet, as shown in Figs. 3 and 5. The distention is formed by applying dies in a manner customary in shaping sheet metal. manner the distention 7 is re-shaped and further distended tothe form shown in Figs. 4 and 6', a circular piece 8' being removed from the center to facilitate the expansion of the sheet during the drawing operation and to leave the bung opening 10. By a third op- In a similar eration performed with a die in the ordinary against the inturned portion 14 of the wall 6, the side edges of the flange 2 will engage the facets 11 and be held against turning.
When the ring is thus positioned with its flange in the cavity the projecting wall of the distention is next set in or contracted circumferentially as shown at 12 (Fig, 9) by applying suitable dies in the customary manner, and finally the distention is upset so as to form a circular shoulder 13 which extends to form a recess having faceted side walls conaround and substantiallyinengagement with the body portion of the ring 1, below the flange 2, with the wall of the distention completely enveloping the flange 2, thereby securing the ring 1 to and holding it in fixed relation with the sheet metal wall 6', as shown in Figs. 1 and 2. The marginal portion 14. of the sheet metal surroundmg the opening 10, lies flat upon the flanged end of the ring and forms an annular seat upon which the gasket 5 is held by the flange of the bung, thus forming an hermetical joint directly between the bung and the sheet of which the head or shell of the barrel is formed. In this manner all danger of leakage from the barrel out between the ring and sheet is frustrated. 4
Another feature of the invention is in the formation of the shoulder 13 that underlies and forms a seat for the flange of the ring. In this'instance the upsetting operation is performed so that the metal sheet is shaped to form a hollow rounded shoulder and thus is avoided the fractures of the metal sheet that frequently occur when the sheet is folded down flat with a sharp bend as in the ordinary manner. It will be noted that in my construction the ring does not pass through the head 6, but is entirely on one side thereof. This provides a surface on its other side for engagement by the annular wall of the plug so that sealing is effectively insured.
To those skilled in the art to which my invention relates, many changes in construction and widely differing embodiments thereof will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
This application is a division of my application filed Jan. 16, 1922,Ser. No. 529,431 (see Letters Patent-No. 1,651,632).
What I claim is:
1. The herein disclosed process of securing a bung receiving member having a laterally extending faceted flange to a metallic sheet, which consists in first forming an opening in the sheet, then in distending the metal around the opening and concentric thereto forming with the facets on the flange of the bung receiving member and an inwardly extending wall to engage one face of the flange of the bung receiving member, and finally inass of the distention about the member, and the final upsetting of the distention upon the member.
3. The herein disclosed process which consists first in forming an opening in a metal wall and distending the metal around the opening to form an annular recess, then in shaping the side walls of the recess to provide contiguous flat portions in angled relations to each other, then in positioning a ring having a polygonal flange into said recess with the outer face of the flange against the inner surface of the bottom wall of said recess and finally contracting the side walls of the recess below the flange toward the body portion'of the ring.
4. The herein disclosed'process which consists first in forming an opening in a metal wall and distending the metal around the opening to form an annular recess, then in shaping that portion of the side walls of the recess adjacent its bottom wall to provide contiguous flat portions in angled relations to each other, then in positioning a ring having a polygonal flange into said recess with the outer face of the flange against the inner surface of the bottom wall of said recess and finally contracting the side walls of the recess below the flange toward the body portion of the ring.
In testimony whereof I have hereunto signed my name.
