Description

T L 0 B E I D m A BUNG.
Pads-ented July 11,1893.
NITED STATES PATENT OFFICE.
ANTHONY J. DIEBOLT, OF CLEVELAND, OHIO.
BUNG.
SPECIFICATION forming part Of Letters Patent NO. 501,058, dated July 11, 1893.
Application filed December 15 1892. Serial No. 455,244. (No model.)
To all whom it may concern:
Be it known that I, ANTHONY J. DIEBOLT, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Bungs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to improvements in bungs for casks, the object being to produce a bung that is simple in construction, comparatively inexpensive and durable; that can be quickly applied and removed from the cask and that, when applied, is perfectly secure against the access of external air to the cask or against the escape of gases therefrom; that can be used with any bushing without liability of being driven downward through the bung-hole, and that has no parts or members projecting outside of the cask when in position in the bung-hole.
With this object in view, my invention consists in certain features of construction and in combination of parts hereinafter described and pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan and Fig. 2 a side elevation of my improved bung. Fig. 3 is a plan View of a bung embodying my invention, the bung being shown in position closing the bung-hole of a cask. Fig. 4. is a vertical section on line 4-4, Fig. 3. Fig. 5 is a vertical section on line 5-5, Fig. 3. Fig. 6 is a vertical section corresponding with Fig. 5, but showing, in position, a suitable tool for extracting the bung. Fig. 7 is a vertical section on line 7-7, Fig. 6. Fig. 8 is a plan of the extracting-tool and bung, showing the tool in position for turning the bung preparatory to the extraction of the bung. v
The body of my improved bung, A, is made of any sufficiently elastic material, such, for instance, as suitably vulcanized rubber, and B represents the core of the bung that is of metal and firmly embedded or seated within the body of the bung A. The metallic core of the bung is hollow or chambered, as at B, and at its upper and lower ends is provided with external annular flanges, b I), respectively. An annular chamber 12 is thus formed into which the elastic vulcanized rubber or the latter, when in service, is exposed to the contents of the cask.
' Figs. 3, 5 and 6 exhibit my improved bung in position closing the bung-hole of a cask.
0 represents the cask; O the bung-hole, and O the bushing that lines the bung-hole. The metallic core of the bung, at its upper end, is also provided with two internal flanges 6 that are located diametrically opposite each other, but the ends of one flange are located sucha distance from the ends of the other flange as to form spaces or openings, b", for permitting the insertion, into the bung, of a tool for extracting the bung, a suitable tool for the purpose being shown in Figs. 6 and 7 that exhibit a bung in position within the bushing that lines the bung-hole of the cask and show, in position, a tool D for extracting the bung with the lateral lugs or projections d in position engaging the under side of inte'rnal flanges b of the metallic core of the bung ready to exert the upward pressure required to extract the bung.
Upon reference to the drawings, it will be observed that the top surface of my improved bung comes flush with or below the outside of the cask and as these bungs are more especially adapted for use in breweries, whose kegs and barrels or casks, as is Well known, encounter rough usage and handling and the bungs whereof are driven forcibly into the casks, it is of no inconsiderable importance to avoid any projecting members at the top of the bung.
' As is well known, bung-holes, or rathertheir bushings internally, are generally, and perhaps universally, tapering or somewhat reduced in size toward their lower ends. The bung is of such size that it will just enter the bung-hole a short distance when placed in position preparatory to being driven into the bung-hole, the elastic body of the bung, of course being compressed upon driving the bung. The upper external flange of the metallic core of the bung is as large or approximately as large in external diameter as any portion of the bung and is preferably flush with the external periphery of the elastic body of the bung, as shown. The external diameter of the upper external flange is, therefore, greater than the internal diameter of the lower portion of the bung-hole-bushing, and hence, no matter how forcibly the bung is driven into the bung-hole, there is no liability of the bung being driven downward through the bung-hole. Spaces or openings 11 between the ends of the two internal flanges of the metallic core of the bung, also permit the application of the extracting-tool (see Figs. 7 and 8) for turning or loosening the bung in the bung-hole preparatory to the extraction of the bung.
What I claim is- 1. A bung comprising a hollow shell provided with integral outwardly projecting flanges at the outer and inner ends and an overhanging integral flange projecting over the hollow interior beneath which a tool may engage for removing the bung, and an elastic body partially enveloping the shell, substantially as set forth.
2. A bung comprising a hollow shell, said shell having an inwardly projecting flange overlapping the hollow interior and provided with integral outwardly projecting flanges at the inner and outer ends of the shell, and an elastic body covering the body of the shell, the inner flange and the inner face of the flange at the outer end of the bung, substantially as set forth.
In testimony whereof I sign this specification, in the presence of two Witnesses, this 26th day of November, 1892.
ANTHONY J. DIEBOLT.
