12 Claims.

The present invention relates to metallic double walled vessels, more particularly barrels in which there is an inner container and an outer casing spaced and insulated from the inner container. The invention is directed more particularly to beer barrels, although it may be used for the handling of any material requiring an insulated container.

The object of the invention is to provide such a barrel which is very strong and durable, and in which the inner container is completely protected from being deformed or otherwise injured by shocks or blows.

Another object is to provide novel means for the effective support and insulation of the inner container.

Another object is to provide a barrel similar in weight and handling characteristics to wooden barrels, and to provide such a barrel which will roll correctly without injuring its finish or appearance.

Still another object is to provide such a container, the inner surface of which is completely smooth and free from corners'or projections, thus defects.

providing free drainage and permitting pitching. In the accompanying drawing, the figure is a longitudinal section through the center of a barrel constructed in accordance with the invention.

Describing the drawing, the numeral I indicates the inner container. This container is somewhat spherical in shape, the walls on all sides being outwardly rounded and the corners being gradually rounded. It is made up of two

sections

2, 3, which are produced by suitable drawing operations, and these sections are butted together and welded along their meeting edges, as at 4. The most satisfactory welding process for this purpose at present appears to be by the automatic carbon arc method, since this method produces a joint of great strength, free from porosity and other The. outer casing, which surrounds and is spaced from the inner container I and supports it, is composed of three sections. The central section is made of relatively heavy gauge material and is formed with a central region 6, spaced parallel rolling ribs I on each side of the region, and inturned flanges 8 at each end of the section.

The rolling ribs 1 are relatively broad and their outer surfaces are transversely crowned. This provides for accurate tracking of the barrel and minimizes the danger of marring the finish of the barrel and wearing the surfaces over which it is rolled.

Adjacent the outer edges of the rolling ribs 1 are formed shoulders 9 which are engaged by the end sections of the casing. From these shoulders, the flanges 8 are turned inwardly to points adjacent, but spaced from the outer surface of the inner container I. At these points the flanges are angularly bent in a direction substantially parallel to the wall of the innercontainer to form rim-like portions Ill. These rim-like portions III are formed to have channels II for the reception of non-metallic packing rings I2 inter- Posed between the rim ID and the container I. The packings I 2 are fireproof and operate both to heat insulate the inner container from the casing and to cushion the container against shocks.

The end sections I3, I4 of the casing are of material of substantially lighter gauge than the center section 5 and are generally pot-shaped, each comprising an annular side wall I5, and a head I6, both of these elements being spaced from the inner container I. telescopically engaged over the shoulders 9 of the central section 5, being butted against the outer sides of the ribs I and having their end portions welded to the said ribs.

A chime I1 is provided on each of the sections I3, I4, by extending the side wall I5 to a point beyond the plane of the head I6, bending it inwardly for a short distance and then bending it back toward the head. The inner surfaces of the chimes I1 are bowed, as shown at I8 to provide a safe hand grip for handling the barrel.

In order to support the end portions of the inner container I and to reinforce the end sections I3, I4, against deformation, reinforcing rings I9 are inserted in each of the sections. These rings I9 are generally U-shaped in section, having legs 20, 2I and central portions 22.

The legs of the rings I9 are secured by welding to the side walls I5 of the end sections and the other legs 2| extend into the chimes II where they are reversely bent to closely fit the outer and end walls of the chimes to provide strong reinforcement therefor.

The central or apex portions 22 of the rings extend to a point closely adjacent but spaced from the end walls of the container I and are channeled as at 23 to receive non-metallic insulating packing rings 24 similar to the packing rings I2. Inasmuch as the rings I9 support the end walls of the inner container I and the flanges of the central section support the side wall, the inner container is maintained against both transverse and longitudinal movement relative to the outer casing.

The rings I9 at a. pointzoutside of the nd .walls These end sections are d of the container l, and adjacent the inner sides of the heads ii are provided with inwardly struck tongues 25 which are welded to the heads l8 and serve to reinforce them.

The barrel is furnished with fittings as follows. The end wall of the section i4 is provided with an outwardly drawn portion 26, having an opening 21 therein for the reception of a tap fitting 28. The tap fitting 28 comprises a central annular nipple 29 outwardly {terminating in a flange 38, a bottom wall 3! and a surrounding annular side wall 32 terminating at its outer portion in a flange 33. The bottom wall 3| is circularly chamfered about the opening of the nipple to a depth equal to the thickness of the wall of the section it, and to the proper size to fit within the opening 21. The head 26 of the section it is provided with an opening 86 having an inwardly turned flange 35 about it for the reception of the flange 33. The tap fitting 28 is welded to the material of the section 3| about the edge of the opening 27, the innermost portion of the said fitting being fiush'with the inner surface of the section 34. The flange 35 of the head It and the flange 33 of the tap fitting 28 are welded together about the opening 3%.

The inner container i is provided with an opening 36, with an outwardly turned flange surrounding it, for the reception of a central bung sleeve 37 in the side of the barrel. The central region 6 between the rolling ribs of the central section 5 is provided with an opening to receive the outer portion of the bung sleeve.

The bung sleeve 36 is tubular and tapers longitudinally toward its inner end. The outer end terminates in a flange 38 which overlies the material of the section 5 about the opening therein. The inner end of the sleeve 36 is flush with the inner surface of the container l and is welded to the container about the opening therein. The flange 31 of the outer end of the sleeve is welded to the material of the section 5, the material of the weld being below the surface of the flange. It is to be noted that the flange 31 is of a thickness less than the height of the rolling ribs I in order to allow the barrel to roll without the flange 31 or a bung inserted in the sleeve 36 coming in contact with the supporting surface.

The above described container has many advantages. The shape of the inner container gives maximum resistance to shocks tending to distort it and change its volume, as well as permitting thorough cleaning and efilcient pitching of the interior. It also allows the container to be rigidly supported within the outer casing.

The air space insulation is comparative in eflect with wood in maintaining beer at proper temperature for a given period without the necessity for extra cooling. Furthermore it allows the necessary operations of super-heating and pitching of the inner container without undue heating of the outer casing, which permits handling a greater number of barrels by brewery employes without discomfort. The flanges on the central section and the reinforcing rings divide the insulating space into seven air chambers and prevent the propagation of air currents.

The freedomfrom obstructions about the fittings permit free drainage and easy pitching.

The flanged bungsleeve having the weld below the surface of the flange, andthe tapered sleeve, allow perfect seating of the filling: nozzle, easy entrance. of the bung, and aid materially in the operation of racking and filling.

The heavy central section of the outer casing provides resistance to the deformation incident to normal handling, and the rolling ribs provide accurate tracking of the barrel and protect the finish thereof. Since the central portion of the barrel normally receives the shocks incident to 6 struction, operation and many advantages of 15 the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to with- .20
