200 FEDERAL REPORTER. �screwed into an iron casing or bushing, haviiig screw-threads on both its outer and inner circumference^ and screwed into the stave of beer barrels; the patent No. 111,352, dated January 31, 1871, issued to Josiah Kirby, for wooden buugs with a hole in the middle, for a veiit-tube, filled with a plug, both bung and plug being made with the grain of the wood running horizontally ; and the patent No. 123,789, dated February 20, 1872, to Otto Netzan and John F. Heck, for an elastic bushing for faucets, tapering towards the interior of the barrel, both on its outer and inner circumferences, with a shoulder on the inside, at the inner end, to bear against the inner end of the faucet. �The original patent of Thompson was for a wooden bushing having the hole for the faucet smallest in the middle, and conical both out- ward and inward, screwed into another bushing or casing made of iron, with screw-threads, to be screwed into the barrel. The claims were for the bushing, constructed and arrangea as described, and for the combination of the bushing and casing, constructed and arranged as described, for the purposes speciaed. The specification of the reissue states that "the invention consists, broadly, in a device com- posed of a rigid aleeve or casing to be inserted within the faucet hole, and provided with a yielding lining;" and the claims are for a compound bushing for faucet holes of barrels consisting of a rigid sleeve or casing, and a yielding lining, as set forth, and the combi- nation of a casing and a lining having a double-levelled internai for- mation, as shown and described, and for the purpose set forth. �The defendant sells beer in casks, having iron casings screwed into the staves, for the bung, like that in the Euegg patent, and like that for the wooden bushing in the plaintifi's patent, with bungs having a hole nearly but not quite throughthem, in the c enter, filled with a plug to bedrivenin by a vent-tube, carrying with it the solid portion of the bung opposite, when the barrels are tapped, like the bunge described in patent No. 148,747, dated March 17, 1874, and reissued in No. 5,937, dated June 30, 1874, to Eafael Pentlarge, for an im- provement in bungs for casks. When these bungs are so tapped by the insertion of the vent-tube, the remaining portion of the bung, with the iron casing about it, forms a compound bushing of wood within iron, for the vent-tube, similar to that described in the plain- tiff's reissued patent for faucets ; and the defendant sells the beer in casks provided with sueh bungs and casings, intending and expecting that the bungs will be so tapped with vent-tubes and used until the beer is withdrawn, and that then the barrels will be returned to be refilled and supplied with new»bungs and the process repeated. �It is true, as has been argued for the defendant, that the double- conical hole for the faucet is shown in the double-conical peg hole ��� �
