BUNG HOLE CLOSURE FOR SHEET METAL CONTAINERS.

lV/T/VESS: g INVENTOR.
BY Wm WM WILLIAM STELAU, OF KANSAS CITY, MISSOURI.
BUNG-HOLE CLOSURE FOR SHEET-METAL CONTAINERS.
Specification of Letters Patent.
Applicationfiled October 9, 1916. Serial No. 124,706.
T 0 all whom it may concern:
Be it known that I, WILLIAM STELAU, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Bung-Hole Closures for Sheet-Metal Containers, of which the following is a specification.
My invention relates to improvements in bung hole closures for sheet metal containers.
My invention is particularly well adapted for employment in sheet steel barrels.
The object of my invention is to provide a bung hole closure for sheet metal containers which will be cheap to make, which will be strong and durable, which will eliminate the welding of any parts, and which in the closed position will afford a hermetically tight joint not liable to leakage.
A further object of my invention is to provide novel means for securing a threaded ring firmly and without soldering or welding' to the sheet metal container.
The novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawing which illustrates the preferred embodiment of my ininternally threaded ring anda portion of thesheet metal member disposed adjacent thereto and showing the flange of the sheet metal member prior to its being inserted through the flange of the ring.
Similar reference. characters designate similar parts in the different views.
1 designates thev sheet metal member.
which may be a portion of a barrel, box'or other vessel or container.
2 designates a ring preferably internally screw-threaded and provided with an annular flange 3 located, preferably, at the inner side of the ring 2 and, preferably, provided on its inner periphery with one ormore notches 4.
The sheet metal member 1 is provided, as viewed in Fig. 1, with an upwardly extending annular portion 5 which extends through the flange 3 and which is provided at its upper end with an annular outwardly extendin peripheral flange 6 which bears against 516 upper side of the flange 3, the opposite side of which bears against the sheet metal member 1, whereby the ring 2 is embraced and secured to the sheet metal member 1.
For holding the ring from turning on the sheet metal member, the latter is forced into the notches 4, as best shown in Fig. 2.
Patented Sept. 1a, 1918.
When an internally threaded ring 2 is employed, there is provided an externally screw-threaded closure comprising a plug 7 which is removably fitted in the ring 2 and which is adapted in the closed position to tightly clamp the flange 6 against the flange 3, thereby preventing any leakage between the ring and the container member 1. If'desired, a gasket 8 of any suitable material such as vulcanized fiber, may be inserted between the closure 7 and the flange 6, as shown in Figs. 1 and 2.
In the manufacture of the device, the annular flange 5 is forced lateraey from the -member 1, as shown in Fig. 4:. The ring 2 is then slipped over the flange 5 with its lower end bearing against the upper side of the member 1. The upper portion of the flange 5 is then forced outwardly and downwardly so as to form the annular outwardly extending flange 6, which is tightlypressed against the flange 3, by dies or otherwise, and at the same time the upstanding portion 5 is forced into the notches 4, thereby firmly securing the ring 2 to the sheet metal member 1. The gasket 8 may then be inserted in the ring 2 so as to bear against the flange 6, after which the plug or closure 7 is screwed into the ring 2 and against the gasket 8 so as to force the latter tightly against the flange 6 and thereby forcing the flange 6 tightly against the flange 3, thereby hermetically sealing the joint between the sheet metal member 1, the ring 2, gasket 8 and closure or plug 7.
- The inner side of the plug 7 may be provided with a screw-threaded hole 9 adapted to have removably fitted therein a faucet, not shown, which during the transit of the container is adapted to be carried therein.
This feature, however, forms no part of my present invention.
I do not limit my invention tothe structure shown and described, as modifications, Within the scope of the appended claim may g3 ma am be made without departing from the spirit tion extending through said flange and en- 10 of m invention. r aglng the notched portion of the flange and What I claim is n aring against the o posite side thereof, In a bung hole closure for a sheetmetal and a screw threade closure removably container, a screw threaded ring having an fitted to said ring and bearing at its inner annular inner peripheral flange provided in end against said annular portion only. 15 its inner edge with one or more notches, a In testimony whereof I have signed my I sheet metal member bearing-against one side name to this specification.
of said flange and having an annular por- WILLIAM STELAU.
