BUNG FIXTURE FOP SHEET METAL CONTAINERS AND METHOD OF ATTACHINGTHE SAME Filed May 9. 1929 flw lfiz/- INVENTOR.

BY %%MM4TTORNEY.

Patented Mar. 29, 1932 THEODORE W. RIEKE, J3 AUBURN, INDIANA,

ASSIGNOB TO RIEKE METAL PRODUCTS CORPORATION, A CORPORATION OF INDIANA BUNG FIXTURE FOB SHEET METAL CONTAINERS AND. METHOD OF ATTACHING THE SAME Application filed Kay 9, 1929. Serial No. 361,687.

This invention relates to improvements in bung fixtures for sheet metal containers, and the method of applying same. The object of the invention is to so construct the fixture l, and form the wall of the container as will admit of clinching the fixture permanently in the wall by a single and simple operation. Another object of the invention is to provide a bun ring with a flange so constructed, and

10. to so orm the wall of a metal container that 16 of providing a flange 3, is

said flange when applied to the wall is clinched in place therein and held from rotation relative thereto, and a further object is to afford a simple and inexpensive method sheet metal container with a bun fixture for the reception of a hung.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a bottom plan view of a bungring, or fixture for the reception of a bung, in which the invention is embodied;

Fig. 2 is a section projected from Fig. 1;

Fig. 3 is an elevation showing the wall of a container as it is formed preparatory to reception of the bung ring, the wall being in section;

Fig. 4 is an elevation showing the bung ring and the container wall after having been preissed in place, the view being in section; an

Fig. 5 is a fragmentary top plan view of the bung fixture in place.

In carrying out the invention, a bung ring 1 consisting of an internally threaded sleeve 2 having at one end thereof an external preferably formed of sheet metal. The sleeve has thereln drain openings 4, and the flange 3 is initially formed with an annular arched rib 5, and the outer marginal edge thereof is serrated.

The wall 6 of the sheet metal container has an opening 7 made therein, and that portion of the wall surrounding the opening is pressed so as to form annular embossments 8 and 9 that project oppositely respecting the general plane of the wall, and the embossment 8 includes an internal flange 10 that encompasses the opening 7 The ring is applied to the wall thus formed by inserting the flange of the ring 3 into the embossment 8 against the flange 10 with the sleeve projectingjahrough the embossmcnt 9 concentrically. ressure is then applied by means of suitable tools (not shown) to the rib 5 and to the embossment 9 whereupon the rib is flattened out so that the flange 3 is straightened into a flat plane and thereby extended outwardly against the wall 11 of the embossment 8, causing the wall to become also extended outwardly beneath the embossment 9, and the embossment 9 is pressed. downwardly and folded upon the face of the flange 3 opposite the flange 10 of the wall, thus confining the ring flange within the embossment 8. Owing to the pressure of the projections 12 of the serrated perimeter of the flange 3 against the wall 11 of the embossment 8, when the ring is pressed into place, the wall is caused to conform to the form of the serrated perimeter of the flange 3, whereby relative turning movement of the ring in the wall of the container is prevented.

The invention is utilized in connection with a hung for sealing the opening 7 in the container, the bung being omitted from the drawings as any suitable type of bung may be employed.

The ring constitutes an immovable fixture in the wall of the container for the reception of the bung for closing the opening therein, and the flange 10 of said wall provides an annular gasket seat for the bung.

What I claim is 1. A bung fixture for a metal container, consisting of a ring having an internally threaded sleeve provided at one end thereof with a serrated external flange that has formed therein an arched rib encompassing the sleeve whereby the outer circumference, upon flattening of said rib, may be enlarged.

2. The method of securing a flanged bung ring in the wall of a metal sheet container. consisting of forming in that portion of said wall surrounding its bung opening, oppositely projecting annular embossments contiguous with each other; forming an annular arched rib in the flange of said bung ring; inserting said flange into place between said embossments concentric with respect to said 100 opening; and applying pressure to said rib and to said embossments whereby the rib is flattened and the outer circumference thereof is enlarged, and one of said embossments is folded over the rear face of said flange.

3. A blmg fixture for a metal container having a wall provided with an opening and formed with two annular embossments disposed around said opening and that project oppositely respecting the general plane of the wall, one of which embosslnents includes an internal flange encompassing the opening and forms a gasket seat, which fixture consists of a ring having an internally threaded sleeve provided at one end thereof with a serrated annular flange that has formed therein an arched annular rib whereby the outer circumference of said flange is adapted to be enlarged upon flattening of said rib so as to be secured to the wall of the container axially alined with the opening therein when said rib and embossments are compressed.

4. A bung fixture for a metal container having a wall with an openingtherein and provided with contiguous annular embossments oppositely disposed respecting said wall, which fixture consists of a ring having an internally threaded sleeve provided at one end with an external annular flange having an arched annular rib whereby when the flange of said ring is positioned within said enibossments, and said rib and 'embossments are flattened, the said flange becomes circumferentially enlarged and secured in said embossments.

' 5. A bung fixture for a metal container having a wall with an opening therein provided with an annular compressible embossment and contiguous flange surrounding said opening, which fixture consists of an internally threaded ring provided at one end thereof with an external radially disposed flange having formed therein a compressible annular arched rib whereby, when the flange of said ring is positioned within said embossment, and said rib and embossment are compressed, said ring is permanently secured to the wall of the container concentrically with the opening therein.

In testimony-whereof I aflix my signature.
