Specification forming part of Letters Patent No. 143,573, dated October 14, 1873; application filed July 3, 1873. i

`To all whom it may concern: Be it known that-I, HTRAM K. HAZLETT, ofthe city andpcounty of St. "Louis, State of Missouri, have invented. new and useful Improvements in Bimgs, lof which the following is a full, clear, and exact description, reference being hereby had to the annexed drawing' making part of this speciication, and to the letters of reference thereon marked, in which- Figure l shows the invention in cross-sectional elevation in position. Fig. 2 is a top view of the bung. 'Fig. 3 is an elevation of the recess in the bung. Fig. 4 is an elevation of the bushing. Fig. 5 is an elevation of the stopper, and Fig. 6 is a top view of the bush- Like letters indicate likeparts.

The object of the present invention is to provide a bung for barrels that is cheap, durable, readily placed 'in position, easily operated in all positions, suitable for venting purposes, and that can be safely locked. It consists mainly of a bushing and stopper of peculiar construction and arrangement, and an interposed washer, all substantially as is hereinafter described and shown.

In the drawing, A, Fig. 1, represents a portion of a barrel of ordinary construction, and B the improved bung in position. The bung is mainly composed of two parts, viz., a bushing or socket piece, and a stopper. The bushingG, Figs. 1, 2, 4, and 6, in its general shape is tubular, and is composed of any suitable metal. It is provided on its outside with a thread. It is of any desirable diameter, and its length by preference is about the thickness of the stave in which it is inserted. On its inside, at its outer end, it is also provided with a thread. Just below the position of this last mentioned thread, or thereabout, the bushing is provided with an inwardly-pro` jecting iiange or ledge, D, Figs. 1 and 6, that preferably extends around the inside of the bushing, and is, on its inside, furnished with shoulders d d1 cl2 d3 d4 d5, of any suitable number or inclination. The bushing is also provided at its upper end with an outwardly-projecting flange, e, which, on its under side, is preferably concave, and shaped so as to elnbed slightly in the stave as the bushing is fastened in place. E, Figs. 1., 2, and 5, repprovided on its outside with a thread to enable it to be screwed into the bushing C. The thickness of the .stopper is about equal to the depth of the inside thread of the bushing. In the top of theV stopper there is a depression, F, that in its general form is annularthat is, it is a depression extending around the stopits inner side as to leave in the center a prolt hl, 85e., and which may be of any suitable shape.

In operation, a wrench, of shape similar to that of the projection H, is passed over the projection, and, by turning the wrench, the stopper is inserted or withdrawn. This part may be operated by a screw-driver, if pre- I, issuitably cut in its top.

In Fig. 1., J represents an elastic washer that restsv upon the ledge D and underneath the stopper E. The bushing is screwed into the stave by means of a key of suitable shape that is inserted into the opening formed by the ledge 1).' lf preferred, the wrench that is used to operate the stopper may be suitably shaped on its outside to form apkey to operate the bushing with. The washer J is then placed on the ledge l), and the stopper screwed down.

A special advantage resulting from the use of the depression in the top of the stopper,

key, is that the bung can be reached and operated when the barrel or kegA is stowed away between shelves. As the bung, by loosening the stopper, can be usedas a vent-hole, and as, in use, .the venting' has to be done when the keg is in an inconvenient place Afor using any tool like a screw-driver, this advantage is more apparent.

To aid in the venting the stopper is made slightly taperin To enable the bung to be sealed it is on top provided with a dovetailed recess, K, Fig. 2, which -enters partly into the bushing, and partly into the stopper.
