Preventing the Aeration of Liquids. — This invention relates to an ap- 

 paratus for preventing the aeration of liquids in the process of withdrawing them 

 from kegs or barrels, and it consists of a metallic tube formed with joints at suit- 

 able points and having at one end a tapering bung-piece within which a corres- 

 pondingly tapered plug fixed upon a smaller induction tube, is removably se- 

 cured. 



The induction-tube hss fixed to one end an expansible rubber bag or similar 

 instrument. Much inconvenience and loss has heretofore attended the operation 

 of drawing fermented liquids, for upon a quantity of the liquid being withdrawn 

 from the cask the atmosphere enters and contaminates the whole. 



In operation the induction-tube being attached to the tapered plug and to 

 the inflatible vessel, the tubular bung-piece which is secured to the main tube is 

 affixed to a barrel or cask of liquid, then the rubber bag is folded into a suffi- 

 ciently small package, and by means of the inflexible induction-tube, it is inserted 

 into the top of the main tube and forced therefrom to the interior of the cask, 

 where it is' inflated correspondingly as the said liquid is withdrawn. 



Meanwhile the tapered plug has been forced to a tight joint within the taper- 

 ing bung-piece. By attaching a funnel to the upper end of the induction-tube or 

 by a similar arrangement, ice water may be used as the inflating fluid. 



After all of the liquid has been withdrawn from a barrel or keg and it is not 

 desired to apply the apparatus immediately to another, the main tube, together 

 with the attached bung-piece and the induction-tube therein contained are first 

 sufficiently loosened in the bung and then carefully withdrawn until the flexible
