JOHN MEYER, OF COVINGTON, KENTUCKY.

VENT-BUNG.

SPECIFICATION forming part o f Letters Patent No. 349,354, dated September 21, 1886.

Application filed Deeemlzer 14, 1885. Serial No. 185,558. (No model.)

To all whom, it may concern:

Be it known that I, JOHN MEYER, a citizen of the United States, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented a certain new and useful Improvement in Vent Bungs and Bushings, of which the following is a specification.

My invention relates to bungs for casks. lts object is to provide a convenient means for venting the cask.

Vith this object in view my invention consists in a hollow bung haifing a valved opening through its wall and the central opening closed by a globe, whichl is compressed within the opening to form an air-tight joint, the device so made forming a vent-bung.

It also consists in certain novel features and combination of parts which relate to the economic construction and effective working ofthe device,all of which will be first fully described in connection with the accompanying drawings and particularly referred to, an pointed out in the claims.

In the drawings, in which like parts are represented by similar reference-letters wherever they occur, Figure 1 is a vertical section of a bun g and bush embodying my invention, sh owing the stopper in the sectional ligure in dotted line and in full elevation above it. Fig. 2 is a detail view. of the parts, the bushing and hollow bung beinglshown in vertical section and the globe or stopper in elevation above it. In this view the hollow bung is made in two parts diametrically divided instead of in one piece, as shown in Fig. 1. Figs. 3 and 4 are diametrical sections ofmodifications of the bung shown in Figs. 1 and 2. Fig. 5 is a similar sectional view of my device adapted to close the faucetopening.

A is a metal bushing for the bun g-hole, screwthreaded externally to be driven into the opening in the casl; by a key or wrench applied to the key-seats a. It is also internally threaded to receive a hollow bung, B, which is externally threaded to engage the screw-threads in the bushing A. The interior of the part B is turned or cored out, forming an annular concave depression to form a seat for the globe stopper C, which is made of rubber or some elastic material. The part B has also keyseats b to receive the prongs of akey, by which bung shown in it is firmly screwed into the part A. The part B has a vertical perforation, b', the lower portion of which is counterbored and screwthreaded to receive a short tube, b2, the opening in which registers with the bore b. Theelower end of the tube b2 has a thin strip of rubber, b3, secured around it and covering the lower end ofthe tube, this acts as a valve to admit air into the cask when the pressure within it is less than the atmosphericpressure and to prevent the flow of gases or liquids in the opposite direction.

The operation of the device so far as described, and as represented in Fig. 1, is as follows: The bushing A is intended to be permanently secured in the cask. The hollow bung Bis screwed into 'the bushing A, after which the rubber globe C is forced into the bung B, where it will be retained in place by the annular depression. After the cask is emptied and is to be refilled the bung B is withdrawn, the Cask is washed and refilled, and the bung B is screwed back to its place. It is obvious that the vent-bore b and its valve at the bottom may be put through the bushing A, as shown in Figs. 3 and 4; but in the case of Fig. 3 it would be necessary to give the bung or bushing B a partial turn to elevate its flange a little above the bung-bush A to admit air for the proper Ventilating of the cask, as shown in Fig. 3. In the form of bushing and hollow Fig. 1 it is preferable to make both the parts A and B of metal and to have them united by a screw-th read, as shown. In the form shown in Fig. 2 the part I3 is indentical in construction with the part B, Fig. 1, eX- cept that it is diametreally divided. In the forni shown in Fig. 4 the part A is left plain on the inside, as the ordinary faucet-bushings are now made. The two-part hollow bung B may be made of wood, plain upon the outside and driven into the bushing, as the common bungs now are, after the globe Chas been placedbetween the two part-s, and in this case the globe maybe made of glass or some inelastic material, which would firmly seat itself in the softer Wood as the part B is driven home. In case the bung B be made of wood and the globe C of glass or inelastic material the vent-bore b and tube b2 should be in the bushing A. Otherwise the bore'b would be closed by compression when the bung is driven into its bushing. The bungs, as above described, are intended i'o be used as vent-bungs.

In Fig. 5 I have shown my bung,` constructed to be used as a faucet-bung. The only differences between the hollow bung B in this figure and the bung` B in Fig. l are that when used as a faucet-bung the vent-perforation b', tube Ir', and its valve are omitted and the interior of bung above and below the annular depression which furnishes the seat for the elastic globe C tapers to iit the tapered Shanks of the ordinary faucets. I intend this form lobe used in combination with my vent-brings before described in the sume casi; or barrel.

In use the globe() will be forcedinto its seat in the faucetbushing B, and when it is desired to tap the cnsk the globe (lis driven into the casl( by the end oI` the faucet, as the eommon cork now is. Alter the eask is emptied the ventbung l1 or 3 can be removed to wash the eask. rIhen the globe C is removed from the barrel through the bushing.

\Vhen B and (l are in use together, they constitute a bung. \Vheu the bung is used at the faucetopening,an(l Chas been driven inwardly out of the bung into the barrel by the faucetshank which is seated in B in the place of C, then B becomes a bushingfor the faucet.

The faucet-bung illustrated in Fig. 5 is not claimed herein, as I intend to make the same the subject of a separate application.

What I claim as new, and desire to secure by Letters Patent, is-

l. Thehollow bung, the valved opening extending through the same, and the stoppcrtl, compressed within the bung, i'or the purpose specified.

2. The bung B, having` vertical perforation If', the tube if, the opening ot` which t'orms the continuation of the said perforation, in combination with the spherical stopper C, substantially as set forth.

fl. The combination, substantially as specified, of the bushing A, screw-thrcaded externally and internally, the bung having a valve-opening vertically through it and thread-v ed externally to fit into the bushing A, with the spherical elastic stopper (l to close the openingin the bung,substautial ly as described.
