16 Claims.

This invention relates to improvements in cony tainer bungs. f

It has for many years been common practice the bung opening and are frequently broken by the mallet resulting in waste of both time and material. Furthermore, latent defects in the wood not uncommonly result in leakage. In addition, when the empty barrels are returned to the brewery, the bung must be bored or chipped out with the result thatv fragments of the wood often fall into the barrel and remain there after Washing.

It is an object of thev present invention to provide an inexpensive metal bung adapted to overcome the above rnentionedobjectionable features. While in the past it has been proposed to employ metal bungs acting in conjunction with rubber sleeves oriwashers to seal the opening, these devices have never been commercially satisfactory as the rubber necessarily comes in contact with the beer and the sulphur contained in the rubber contaminates the beverage. Furthermore, these bungs are not capable of remaining securely in position when subjected to the joltsr occurring during the handling and transportationof barrels. v

A more specific object of the invention is to provide a container bung in which a metal screw coacts with a sleeve of deformable metal to permanently and securely seal the barrel opening.

A further specific object of the invention is to provide a device of the class described which may include a shield for the deformable metal to prevent the latter rfrom coming in contact with the beer and also to prevent any leakage of beer through the screw threads. 1

A further object of the invention is to provide a container bung which can be removed, when the empty barrel is returned to the brewery, by means of a special pulling tool, there being no possibility of any foreign matter falling into the barrel during such removal.

A further object ofthe invention is to provide a metal container bung which is constructed to yreadily receive a disc label or seal, which label may bear the date of the brew and' any desired advertising material, and which further is so held in .position as to make it impossible to tamper with the bung without first mutilating the label.

A further object of the invention is to provide a metaIbung, which, while particularly adapted for use in connection with beer barrels, is nevertheless susceptible of a wide range of other uses.

With the above and other objects in view the invention consists of the improved container bung and all its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals designate the same parts in all of the views Fig. 1 is a longitudinal sectional view through the bung opening of a barrel showing the improved bung in position therein before it has been locked in place, the dot-and-dash lines indicating a turning tool cooperating therewith;

Fig. 2 is a similar sectional view showing the bung in sealing condition;

Fig. 3 is a plan view of the bung opening with the improved bung in position therein;

Fig. 4 is a perspective View of the screw element alone;

Fig. 5 is a perspective view of the improved bung alone in condition for use;

Fig. 6 is a plan view of the bung opening showing a label in position on the bung; and

Fig. 7 is a View similar to Fig. 2 showing the special pulling tool in position for removal of the bung from an empty barrel, parts of the tool being broken away and shown in section.

Referring more particularly to the drawing, the numeral 8 designates a fragment of a container surrounding the usual bung opening 9. Said opening 9 is fitted with the usual downwardly and inwardly tapered metal bushing IU, which bushing terminates short of the interior of the barrel as at il. The bushing may further be formed with the usual exterior ange l2.

The improved bung consists of two parts, a screw I3 and a sleeve lli. The screw may be formed of any suitable metal, but is preferably of cast iron or steel. The threads I3' may be either cast thereon or formed on a screw machine. The upper end of the screw is of somewhat less diameter than the lower end thereof to provide sides which are tapered in a reverse direction to the taper of the sides of the bushing. In addition, the lowermost screw thread l5 projects laterally beyond the other screw threads for a purpose to be hereinafter described in detail. The upper end of the screw is provided with an opening of any desired shape for cooperation with a turning tool. In the drawing a circular opening i6 is illustrated which has a laterally extending key slot Il, the opening I6 communicating with a larger opening I8 therebelow. It will thus be seen that this opening is adapted to cooperate with a turning tool YI9 having a round lower portion 2S formed with a projecting key y2l for cooperation with the key slot I1. The opening I6 may, of course, be rectangular for cooperation with a rectangular end of a different type of turning tool.

After the screw is manufactured the sleeve I4 may be formed by pouring metal around the'screw as the core of a mold. The sleeve i4 is preferably formed of lead and has its interior opening tapered to conform to theY taper of the screw inasmuch as some breweries vmay object to lead coming in contact with the beer, it is preferred to utilize a cup shaped shield 23 on the bottom of the sleeve. This shield is preferably 0f aluminum foil.

In actual practice, in manufacturing the bung, the aluminum foil is first pressed into the cup shaped form and placed in the bottom of a mold. The screw i3 is then centered within the shield and the lead or other deformable material is poured into the space between the sides of the mold and the screw. This causes the foil shield to be cast into the lead sleeve as an integral part thereof and to be'indented into the sides thereof so that the sides of the sleeve, with the shield thereon are flush from top to bottom. While aluminum foil is the preferred material for the shield, other suitable sheet material may be employed. After therbung assemblage has been Y manufactured as above described, it is preferable to place it in a vibrator to break the adhesion between the screw and the lead so that the screw Y V'extends in a reverse direction to the .taper of the sides ofthe bushing l0, and to the fact that the bottom screw thread l5 projects laterally beyond the other screw threads, the result of this upward turning is a deformation of the lower portion of the lead sleeve as shown in` Fig. 2 so that the sleeve is pressed tightly against the sides of the ybushing and so that its lower portion is flared outwardly to prevent withdrawal of the bung. It will thus be seen that with this method of deforming the lead sleeve, that no jolts however severe can disturb the secure sealing effect. It will further be seen that the foil shield 23 prevents the beverage and gas from coming in contact with the screw and sleeve, and possiblyfleaking out through the screw threads. The shield may extend any desired'distance upwardlyon When the empty barrel is returned tothe brewery, a special pulling tool may be employed toV remove the bung from `the opening. As shownV The lower ends of the fingers may be recessed as at 32.

When the ngers are compressed theymay be inserted in-the opening 2c o-f the screw and dropped to the position shown by loosening kof the nut 28. When in proper position, a cam or the like 33'isturnedby means of a lever 345 to expandV the lowerends of the fingers. Next by turning 'downwardly on Vthe Vnut Y2il,Y the screw 21 'tion against tapers 3l tothe expanded position Y Vshown in, the gure.

and fingers are raised causing theentire bung to beV forcibly pulled out Yof the bung opening.

VInstead of the cam resilient means may-be em-fl ploycd between the lingers tonormally hold them in expanded'position so that the ngers can be When the bung is removed, the lead ring' will,A of course, be mutilated. The screw however is in condition for re-use, and they screws may be A' returned by the brewery to the manufacturer and used asa credit against new bung assemblies.Y As' an alternative the manufacturer ofthe bungs may i furnish only new lead sleeves and separate shields 23 so that the brewer'can reassemble his own bungsusing the screw portions i3 over andfover again. f

. l Vl0 From the above it may be seenthat avery simple form rof bung has been provided which is y highly satisfactory due to the Vuse of distortable metal for .the sleeve. This metal is the principal feature of the invention in viewY of the fact that when distorted by upward turning of the screw,Y

end of the bushing to absolutely prevent loosening or removal without the Vuse of the pulling tool.

`It will further, be seen that the shield absolutely prevents any` contamination of the beer from the materials which might be used in the bung. In addition it will be seen that with the method of removal provided, there is no danger of any foreign matter falling intoV thebarrel such as is the casefwhenrwooden Ybungs haveto" be chipped'orbored out. Y V

Although only one -form'of the invention has been shown and described, is obvious that variouschanges and modifications may 'be made withoutdeparting from the spirit of the invention, and all of 'such changes are contemplated as may come within the'scope Yof Vthe claims.Y
