2 claims. (ci. 11s- 120) The present invention has to do with a mletal lic container andv more particularly with a metal barrel for liquor such as beer and the like.

It' is an object of the present invention to constructV a metalliccontainer or barrel 4which may be manufactured be satisfactory for the purposes intended.

' Another objectof the invention is to provide a metallic container for 'beer and the like of improvedonstructionf .A further object of the invention is to provide ansingle wall metal barrel or container suitable for beer and the. like, which. barrel is strong and sturdily constructed to withstand the hard usage to which a Another and-yet further objectofthe invention is to provide a novel method of attaching a lling bung bushing in place in a metal barrel. v

A rstill further object of the invention is to provide a' metal whereby one head or both heads may be readily n removed for replacement or repair without damaging any partof the barrel. A

Theabove, other and further objects of the Y invention will be apparent from the following description, accompanying drawings, and. appended claims Generally speaking, the'barrel contemplates a body portion made of a single thickness of metal constructed initially as a cylinder, the provision ofa bilge ring having in it a plurality of runners or ribs which are arranged Qcircmferentiailly of the img and nu` which the inner surface of the ring is concave. by expansion of fthe body to secure intimate t of the body and ring. Furthermore, the invention contemplates the securement of 'a' bung bushing in the bilge ring,and after' the barrel body has been expanded to provide the bilge in it, the body] of the barrel bung bushing is/perforated, using the bung as a punch, the margin ofthe body dening the aperture being s'ecured tothe bung bushing.

Figure 6 is a view similar to Figure 5 showing y the manner of curling the margin of the hole in the barrel body into a recess formed in the bung bushing.

The drawings will now be explained.

'I'he metallic container of the present invention includes a body A which is made initially as 20 a cylinder andpreferablyfrom at stock bent with the abutting edges welded together in any suitable manner. Near each end of the body A is formed an annular shoulder I which extends about the bodynear the ends means to lmiththe inward position of the head of the barrel when the'same are applied. l

`There are two heads B and C, each of which -is provided with a cylindrical iiange 2 disposed to extend youtwardly towards the-.end of the barand serves as '25 rel or container when the heads are applied. Preferably, the heads are dished at 3 for the pury pose of rigidity.

At each end ofthe barrel is provided an end generally at D, which ring has av flange p ortio'n 4 for bearing against the outsides of the ends of the barrel and an inturned portion substantially right angles to the flange Il,` and which portion 5 provides a hand -hold for lifting and carrying the barrel. The portion 5 isformed'by inturning a part of the material of whichthe ring D is made. The entire body is tinned on both .sides as at 6 and 'l after the 'body has been fashioned incylindrical form. The heads and the rings are also tinned all over'the same. Y 'I'he bilge ring is tinned, inside and outside, afterthe filling bushing has` been secured to A the bilge lring. The head melt the tin and thus the parts are sweated together in permanent association.

'I'he installation of the heads and the rings D in the mannerjust described is effected after the bilge ring has been applied to the barrel and the 4body subjected to expansion action to form lthe There are thus formed runners F and G. Formation of the runners by expansion of the ring forms llets 32 between the plane of -thering and the faces IIl of the runners. In order to reduce the fillets to walls which are substantially perpendicular to the planeof the body of the ring, that is to the anges II and I2 of the ring, the ring is then rolled whereupon'the fillets are reduced to theshape shown at I3 and I 4 of the runners F and G. In this manner the walls I3 and I4 arc `between the ribs, as at 33 in Figure 4, to provide a seat for a lling bung bushing.b The offset porsubstantially perpendicular to the planes ofthe anges I2 and II of the bilge ringand consequently substantially perpendicular to the expanded body of the barrel so that it is possible to make the1bi1ge ring of lighter material than otherwise possible where these walls are not substantially perpendicular to the surface of the barrel. The rolling of the ring, as just described, also dishes the flanges II and I2 of the bilge ring to provide a concave inner surface on the ring. The degree of concavity of this ring when rolled is slightly greater than the finished expandedl bilge of the barrel when completed.- By providing the concave surface in the bilge ring, then' when the barrel body is expanded, the flanges II and I2 of the ring are stretched thus increasing the holding effect between the ring and the barrel.

After the bilge ring has been fully formed, it is then subjected to tool action to press outwardly or offset a part of the cylindrical portion tion 33 is then punched, providing a bushing aperture 34.

In order to apply a filling bung bushing to the barrel, a bushingy H, preferably of steel, is provided. The bushing is illustrated in section in `Figures 1, 4, 5 and 6, and is formed with a central opening I5 which tapers inwardly for receiving a bung or other sealing 'means afterthe barrel has been lled.' When the bung bushing H is formed, there is formed in it an annular4 recess I1 opening toward the lower side of the bushing. In the formation of the bung bushing H the edge I8 is -formed as sharp as possible for Jthe purpose of utilizing this edge as a punch for a purpose to beV later explained.

'I'he bung bushing His inserted in the aperture l34 in the bilge ringE in the space between the runnersF and G from the inside of such aperture.v Y. The outer portion 'of the bung bushing hasan upstanding annular ange I9 which projects through the aperture or hole 34 in the bilge ring E with the-margin of such hole surrounding the shoulder I 9 at its base. The bung bushing is then welded as at 20 to the bilge ring E, the vwelding being done against the inside of thebilge ring surrounding the bung bushingH.

After the bung bushing H has been applied to the bilge ring in the manner'stated, the ring and bushing are completely tinned and the'bilge ring E is then applied over the cylindrical body of the barrel A and the barrel A is then subjected to expansion action to produce the bilge in 'the barrel. Such expansion of the barrel body forms generally the barrel body to the concavity of the bilge ring E and thus intimately connects the bilge ring to the barrel body by such expansion action.

The present invention contemplates the formation of the bung hole in the-barrel body in the following manner:

After the bilge ring has been secured to the ignated 2 I in Figures 5 and Grand having a reduced portion 22, is applied against the exterior of the bung .bushing H with the part 22 entering the vaperture oropenlng I5 in-the bushing with the shoulders 23 of the tool bearing against the outer surface of the v.bung bushing. -The part 22' is tapered, slightly, at 24 for the purpose of centering the tool 2I in the bung bushing H.

A die 25 having a sharpened edge. at 2S is then applied inside of the barrel body in augment upon there is blanked or punched out from the barrel body, a blank 21. Movement of the die is continued to force the portion indicated at 28 of the barrel body A forming the marginal portion of the hole so pierced into the recess II of the bung bushing. During such action the' margins of lsuch hole become distorted'and crimped in the recess I1, as may be observed from Figure 6( When this has been accomplished, the member 2l and die 25 are removed, and then the deformed marginal portions of the hole are .welded or sweated in the recess II as indicated at 28 in Figure 4, thereby permanently securing the bung bushing H to the barrel body A and to the bilge ring E.

In this manner there is provided an opening in the barrel body in register with the lling bung bushing H, which is of proper size and which is so secured to the bung bushing4 as to make a leak tight joint.

Friar to the installation of the head B, a tap bush 29 is inserted in the headB and` secured `thereto by welding as indicated at 30. 'The parts are s o fashioned thatV the bung bushing H lies within the surfaces or faces I0 of the' runners F and G while the tap bush 2 9 is within the extremity of the end ring D at this end of the barrel. Y y

In the rolling of the runners F and G,y porsurfaces for rolling the barrel.

-tio'ns of the surfaces thereof, as for instance' It will be observed from that the bilge ring. E extends over the major portion of the body of the barrel when the. structure is completed.l The bilge ring so applied' reinforces the body of the barrel and prevents damage to Athe barrel duc to rough usage.. It will be observed from Figure I thata very small portion ofthe bodyAof'thebarrelisexposedtoi-,migh treatment, as most of the surface of the barrel 1S protectedby the y meiegnanameend ringsD. J

By'thefumizanon 'of huge ring of the. character herein described, a single walled barrel is provided which is strong and sturdy and which will stand the rough usage to which barl rel, the damaged head reis, such' for instance as beer barrels, are subjected in handling. i r Y If perchance it should become necessary .to repair or replace .either of the heads oi the barmay be removed by subjecting that end 'of the barrel to, sufficient heat to melt the solder whereupon the head may be -moved without damage to any. part of 'the barrel and the head so 'removed repaired or replaced by a new one.

The provision of the flattened surfaces 3| on the nmners or ribs prevents tilting of the barrel endwise when on the runners. a feature which is desirablewhen the barrel is being rolled or when it -is being carried n a truck or wagon or stored. y

Tinning the entire body and heads of the container, as well as the bilge ring, prevents rust,

` and thus prolongsthe lusefulness of the container. f l

"When such container is used for beer, the insides of-the body and heads ,are covered with pitch. In the event any of the pitch should chip off, the tinnedmetal would prevent rust and spoilage of the Whenever the tap bush 29 is placed elsewhere than in the center of a head, then the opposite vhead is provided with a'well for the reception of the beer pump rod.
