eusHlNG FOR BARRELS.

SPECIFICATION forming' part of Letters latent No.'723,553, dat'ed March 24, 1903. Application filed February 6, 1902. Serial No. 92,813. (No model.)

To all whom it may concern:

Be 1't known that I, FRANK C. ScHoENTHA- LER, Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bushings for Barrels, of which the following is a specification.

This invention relates to that class ofbush ings which are adapted to be used for barrels containing liquids-such as ale, beer, and the like-and to the particular constructionof bushing which partakes of the function of both bush' and faucet, so that it can be used economically and efficiently to draw the liquid out of the barrel, as will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and eflicient bushing for beer-barrels.

Other objects of the invention Will appear from an examination of the drawings and the following description and claims.

The invention consists principally in the combination of a bushing provided with a central axial opening for the insertion of a discharging-tube, a ring inserted in such axial opening and provided with an air-supply 'pas- Sage, and means for holding the parts in operative position.

The invention consists, fu rther, in the combination of a bushing provided with an axial stepped passage, a' removable ring provided with an air-passage restingin such axial passage, and sci'ew mechanism for holding the parts in operative position.

The invention consists, f urther, in the combination of a bushing provided with an axialstepped passage for the insertion of a discharging-tube, the bottom having a smooth bore and the upper a, larger threaded bore, a

removable ring provided with an upwardlyland outwardly extending stem containing ani air-passage, a cushioning sealing-ring, anda screw'-nut for holding the parts in operative position. f

The invention. consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is' a Vertical sectional elevation of a bushing in position in connection with the Walls of a I the air-tube in cross-section on line 4of Fig. 3.

In the art to which this invention relates it is well known that manufacturers of beer kegs and barrels providethe same With a metallic bushing into which the ordinary plug may be driven to seal the barrel and 'that in use'this plug must be-removed and a faucet or similar element for the withdrawal of liquid substituted in place thereof. It is also well known that the manufacture of the bush and faucet plugs is very expensive in that they are made iu two separate and independent parts containing a number of pieces, so that the combined cost of all these pieces when made in large quantities amounts to a large sum. Fu rther, it is sometimes very difficult and annoying to place the faucetplug in operative position in that it projects considerably beyond the package, which renders it liable to injury and disturbance.

Myinvention therefore is intended, primarily, to remove the above-noted objections by providing a bushing which is, in effect, acompound bush and faucet-that is, one compact niechanismvwhich accomplishes the functions, advantages, and results of a bushingand faucet plug, dispensi'ng largely with the annoyance attendant on the use ofthe ordinary bush and bung. It willalso be noticed that the mechanism'is very compact and does not in any way project to materially affect the handling .of the package, and tinally that it is simple in construction, economical to manufacture, and efficient in operation, all of which will more fully hereinafter appear.

In constructing a bushingin accordance with these improvements I provide a bushing portion a, screw-threaded on 'its outer periphery,

as at b,- and having an upper annular'shoulder or flange portion c, thewhole adapted to :be screW-threaded into engagement with the Walls d of a beer-barrel or similar element, as shown particularly inFig. 1.

The bushing is provided with a central axially-disposed stepped opening having a pas- Sage c, as shown in Fig. 1, of two diameters, the

IOO

lower diameter being a smooth bore and terminating in the tubular projection fat the lower end of the bushing, while the upper and larger diameter of this axial bore is screw-threaded, as at g, the end at or near a shoulder h intermediate the smooth and threaded bores.

It is desirable to provide means by which the liquid maybe withdrawn from the package. T o accomplish this` result, a discharge tube or pipe t' is provided and passed through the axial opening of the bushing. In order to hold this in place, screw mechanism is provided, consisting of a rubber or cushioning washerj and a ring-nutk. The ring-nut engages the threaded bore of the bushing, forces the cushioning-washer downwardly, spreading itat the same time, so as to firmly clasp the discharging-tubc, hold itin position, and seal the opening against the discharge of liquid. It. is also desirable to supply air under pressure to the package, so as to force the liquid out through the discharge-tu be. To accomplish this, I provide a removable ring l, which is arranged in the stepped axiai opening and against the shoulder thereof, the lower portion of which is preferably provided with a sealing-seat m, similar to a valve-seat, to form a Seal between the ring and the shoulder, such seat being preferably formed of rubber. This ring has forxned integral therewith and extending outwardly and upwardly therefrom an L-shaped tubular projection n, havingr an air-passage 0 eX- tending through such portion and ending at theinnerboreofthering,whichinnerboreis of slightly-larger diameter than the dischargetube, so that air may enter the space between the ring and the discharge-tube, and thence through the passage e under the package to be used whenever desirable or necessary for the forcing out of the liquid. The upper part of this air-passage is provided with a nipple p, which contains a threaded plug'pro- Vided with a check-Valve q, formed of a flattened rubber tube, which permits the introduction of air under pressure, but prevents it or any liquid from` escaping. It is desirable that this ring, with its air-tube, should be prevented from rotating in order to economize space. To accomplish this result, one portion of the Walls of the bushing is slotted or grooved, as at r, so vas to permit the airtube to enter therein and act to hold it firmly in position against rotation. The ring-nut should be slotted, as at s, so that a proper wrench may be used to place it in position or remove it therefrom. The bushing should also have a second slot 25 opposite the groove 'r, so that a wrench could also be used successfully here for the insertion or removal of the bushing, it being understood, of course, that the bush is put in position after the barrel is made and that :it is oftentimes necessary to remove it therefrom for purposes of repair and renewal.

In operation the bushing is supplied by the manufacturer and a cork or plug driven in the passage e, which prevents any liquid from escaping. The ring, With its air-tube, is removed, so that as no air can pass through the walls of the bushing there is no danger of any liquid escaping. The user is supplied with one of these rings and air-tnbes, which he can use With any number of barrels, and as this ring and tube are only in place when the harrel is used it will be seen that the package can be handled without any disagreeable effects to the hands or annoyance to the operator. i
