IMPROVEMENT IN BUNGSAND BUSIIES.

TO ALL WHOM 1T MAY CONCERN:

Beit known that I, JOHN BUEGG, of St. Louis, in the county of St. Louis, and State cf Missouri, have made certain 4new and useful Improvements in Bungs for Barrels; and I'do hereby declare 4that the following is a. full and cleardescription. thereof, reference being had to the accompanying drawings, and to the letters of reference markedrthcreon.

The objectvof this'invention is to produce a bung and bushing for beer and other barrels that will he capable of enduringtherongh usage that bungs are usually subjected to by being continually inserted and 4withdrawn from barrels. I am well aware that iron bushings-have before been used -for barrel-brings, but` they have always been attached to the barrel by means of rivets alone, and consequently have readily become loosened. Into these metallic bushings wooden plugs have been driven, and these have, as a matter of course, caused the barrel to be pounded with a heavy instrument, for the purposeof the withdrawal of the bung,and this pounding has, as it'inevitably must, caused* the rapid destruction of that stave of the cask in which it was placed. Then the bung was so securely driven in that much time and labor were required towithdraw it, and it was consequently difficult vand tedious to withdraw the bung slightly for thepurpose of giving ventito the cask. To remedy these. evils, and more especially the last, is the object ofthe present invention. In this case a metallic bushing is used, whichis to be beth screwed into the staveand riveted to it. Then' the bung is screwed into the bShiPg, and 2. Cap-plate screwed down-.otter it. so asto thoroughly` protect it during transportation. An airchannel is cut'in 'one side of the bung, for the purpose of admitting air to theinterior of the cask for vent, when the bung is but slightly withdrawn.

To enable thoserskilled in the art to make'and'use my improved bung, I will proceed to describe its construction andoperation. y v i .Figure lof the drawings is a plan of the improved-bung and bushing.

Figure 2 is a plan of the same, having the exterior cap removed. i' Y 1 'Figure 3 is a sectional elevation. l i Figure 4 isa plan of the bung without the bushing. Figure 5 is a perspective view of anotherv form of my invention. l

` The Vbushing"consists of a neck-piece, A, and aflange, A. -The neck-piece A. has both its interior and exterior surface provided with screw-threads. The exterior threads a arci for the purpose of screwing the bushing inte .the bung -stave, while the threads a, or the interior threads, are for the purpose ot' securing thel bung-into-the bushing. In addition to the threads a, as a means of securing the bushing to the stave, the flange A is provided with a-series of holes, a2, through which rivets are to be inserted and 'secured to the stnvcl- The bung B is a cylindrical stopper, with screw-threads on its periphery adapted to tit the screw-threads al of the bushing. The top end of the bung is recessed, so as to form a central square shank, b, adapted to the applica- 'tion of awrench for the'purpose of screwing the bung into the bushing. On one side ofthe bung is a channel, b, as seen best in l'igf4. When the bung is screwed down tightly into the bushing its bottom lend will form a tight joint on thepacking a?, which rests uponau annular scat formedv on the interior of the bushing, but when the bung is slightly unscrewed a. sufficient amount Ot' external air will pass through the channel b to afford vent for the barrel, and ,in this mannerjust enough 'and no more air may be 'admitted to afford the required vent, and

the contents of the barre-l will in consequence remain sweet a longer time than if the air were allowed to enter? in larger volumes. `When the bung is screwed clown tightly into its bushing a. cap-plate, C, is to be placed ovcr it, and secured to the bushing-Harige by means of the screws c.

Fig. 5 represents another form of my invention, in which the outer surface oF the bushing :is runde conical,`

the taper being downward, so that the bushingr may be screwed more tightly'into the stave.

Having described my invention, whatmI claim is- 1.. The bushing A A', when provided with screw-threads a a and rivet-holes a?, and with a. cap or lockplate, C, as described and for the purpose set forth.

2. I claim the bung B, when provided with screw-threads, by means of which to secure it to the bushing,

" "zndvthe vent-channel b1, and wrench-shank b, as and for the purpose shown and described.

ln testimony of which invention I hereunto set my hand in presence of-.-
