EBANII GAREIS, OF BUFFALO, NEW YORK.

BUNG- FOR RACKlNG-BARRELS."

SPECIFICATION forming part of Letters Patent No. 272,039, dated February 13, 1883.

Application filed December 13. 1882. (No model.)

falo, in the county of Erie and State of New York, have invented certain new and useful 5 Improvements on a Bung for Racking-Barrels,

860.; and ,I do hereby declare that the following description of my said invention, taken in connection -\Vll'.ll.'th6' accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

a My present invention has general reference to bungsfor racking-barrels and similar storin g-vessels for beer, ale, &c.; and it consists essentially in the peculiar. and novel combina- 1 tion of parts and details of construction, as

hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already referred to, which illustrate my said invention more fully, Figure 1 is a side elevation of myimproved bung and racking-cock. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is aplan. Fig. 4 is a side elevation ofthe bung-expander, and'Fig. 5 is a plaii of the same.

Like parts are designated by corresponding letters of reference in all the figures.

The object of my present invention is the production of a simple and effective expansible bung and stop-cock combined, which can be readily inserted into the barrels, casks,hogsheads, 850., and as readily withdrawn therefrom as occasion requires. To attain'this resuit I construct a bushing, A, of india-rubber or other similar elastic substanceormaterial, in the form of a hollow truncated cone inverted, its exterior size or dimensions depending upon the size of the hung-holein connection with which the bung is to be used. The upper or largest end of this bushing is contracted at D, so as to receive an exteriorly screw-threaded band, D, and an interior locking band or book, 0, the contracted part D beingarrangd to project beyond the faces of the bands B C, so as to form a packing-ring for the cap E, screwed over the screw-threaded band B. I In this cap E is a screw-threaded aperture, through which (or rather into which) the shank F of a faucet, F, is passed by means of itscxterior screwthread, as clearly shown in Fig. 2. Thelower end, F, of the shank F screws into a recess.

h, in the upper end, l,of a tapering plug For body, H, located in the correspondingly-shaped core of the bushing'A. soas to make a rigid and fixed connection with said body H.

in operation the cap E is first removed from A the bushing A and the faucet F screwed into the cap. Now the body H is attached to the faucet F on the screw end F and the capE re; placed. The bungis then loosely inserted into the bung-hole in the stave P, after which the faucet F is screwed downwardly so as to force the body H downward in the bushing A, thereby expanding the lat-terso much as to cause it to be tightly wedged into the bung-hole. Its

removal from the cask, barrel, &c., is an impossibility unless the plugH is first withdrawn from the bushing sufficiently to allow it to contract to its normal size.

0n the upper end of the faucet F is provided an external screw-thread, G, by meansof which and a suitable hose andvooupling connection may be established with an air-pump, an acidgenerator, or any other-device,apparatus, ma

chine, &c., the-plug H being provided with a passage, h, forobvious reasons.

I have constructed this expanslble bun g with an especial view to its use in connection with the storing-tanks or hogsheads employed in breweries for holding lager and other beer. In these tanks, &c., it often happensthat the carbonic acid generated by or in the liquoritt.

creases in pressure a predetermined limit, and for this reason provision must be made for the free and unobstructed escape of the surplus gas. This is accomplished bysecuring (screwing) a safety-valve onto the screw-threaded portion G of the faucet F. I have devised one such apparatus, for which application for Letters Patent will be duly made, and 1 do not therefore show such devicein connection with the present invention, Although designedsubstituting for the faucet F a common screwbolt, (not shown,) by means of'which the plug H may be operated from the outside of the bung.

Having thus fully described myinvention, I claim as new and desire to secure to me by Letters Patent of the United States- 1. As a new and improved article of manufacture, an expansiblc bung consisting of a hollow tapering elastic bushing, a cap having an internal screw-thread, a tapering plug fitting theinterior of said bushing, and a screw device passing through a threaded orifice in said cap to actuate said plug from the exterior of the bung, as and for the object specified.

2. A bung for beer and other casks,-consisting of an elastic tapering bushing having on its 'upper end an exteriorly" screwthreaded band, a cap screwed to said band and provided with a screw-threaded aperture, and a threaded device, substantially as specified, passing through said cap and actuating an expansion device within said elastic bushing, substantially as'described, for the object stated.

3. The combination, with the elastic bush- 25 in g A, having on its upper end a screw-threaded collar, B, and a locking-band, G, of the cap E, faucet F, having the screw-threaded shank F passed through a threaded orifice in said cap E and engaging with a hollow plug, H, the whole being constructed for operation substantially in the manner as and for the object stated.

4. In expansible brings, the bushing A, having the contracted portion D, provided with an exterior band, B, and anvinterior 'band,'O, said portion D projecting beyond the face of said bands and operating in conjunction with a cap, E,suhstantiall v as described and stated.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the presence of two subscribing witnesses.
