s` claims. (o1. 22o-1o) This invention relates to double walled containers and more particularly to double Walled beer barrels made from sheet metal stampings and provided with a removable or permanent liner made of a material suitable as a container for beer.
By constructing such a barrel with double walls, a number of advantages are gained thereby. A sturdy construction of sufiicient rigidity to withstand the hard usage to which these barrels are ordinarily subjected can be formed of relatively thin sheet material by' stamping methods, portions of the total structure being made in sections which are subsequently secured together, and yet the total weight can be kept within satisfactory limits. To accompany the advantage of using sheet metal suitable for stamping, provision is made for the lining of the inner shell so that the metal itself need not be one that is especially adapted because of its inertness for the reception of beer or other edible Products.
A double walled construction is readily adapted for the provisions of an opening into the interior shell, larger than the usual filling opening or tap rod opening such as are usually provided in wooden barrels, for example. Such an enlarged opening can be used to facilitate'the cleaning and the inspection of the barrel, and may also be used for the insertion and removal of a separate removable liner, such as is described hereinafter.
Another advantage which resides in the double wall construction is that the space between the inner and outer shells may be employed for the circulation of a cooling fluid such as water.
Accordingly, one of the objects of this invention is to provide an improved double walled container and improvements in the manufacture thereof.
Another object of the invention is to provide a double walled container so designed and constructed as to be appropriately fabricated from thin sheet metal stampings which may be readily assembled into the nished product.
Another object of the invention is to provide improvements in the manufacture of double walled containers provided with unusually large openings to facilitate the cleaning of their interiors.
Another object of the invention is to provide an improved form of double walled container with a removable flexible'liner and means facilitating its insertion and removal.
Another object of the invention is to provide an 2 improved form of double walled container which may be made of sheet metal stampings and provided with lining material which will render the container suitable for the reception of beverages,
or other edible products.
Another object of the invention is to provide a double walled container so constructed as to facilitate the circulation of a coolant between the inner and outer shells of the container.
Other objects and advantages or the invention will be alluded to specifically hereinafter or will become apparent from a perusal of the specification. v
In the drawings, which illustrate a preferred form of the invention,
Figure 1 is a vertical central section through a container made in accordance with the present invention;
Figure 2 is a top plan view on an enlarged scale showing the bung end of the barrel;
Figure 3 is a sectional view on the line III-III of Figure 2;
Figure 4 is a central vertical section of the top portion of the barrel showing the bung opening assembly in an exploded view; and
Figure 5 is a sectional view on the line V-V of Figure 4.
Referring further to the drawings, the barrel generally consists of inner and outer shells, the outer shell being formed from two sheet metal stampings II and I2 constituting the upper and lower halves of the completed outer shell. The
upper half is provided with an annular chime I3 while the lower half is provided with an annular chime I4. The bottom wall I5 is recessed inwardly considerably from the plane of the outer surface of the chime. The top wall I 6 of the outer shellis provided with a large central opening in which is xed a removable assembly which carries both a bung opening of standard size and an enlarged opening whose purpose will later be described.
The inner shell is likewise formed of two sheet metal stampings which are afterwards united to form a single inner shell. It may be pointed out here that due to the use of lining material for the protection of the beer it is not necessary to use for these stampings a metal which without other treatment is suited for a beer container. Accordingly a mild steel well adapted to the forming of the stamping of the character shown may be used.
The inner shell, formed of an upper stamping Il and a. lower stamping I8, is designed to be united securely to the outer shell by means of angeo Il and 2| formed on the upper and lower halves respectively of the inner shell, these flanges being united to each other by welding. prior to placing the inner shell inside of the outer shell. At the time the inner and outer shells are lplaced together the perimeters oi' the flanges are brought into abutment with the opposing edges of sections Il and l2 of the outer shell after which the flames and the two outer shell edges are all welded together in one operation. Thus the ilanes furnish a means for uniting the inner and outer shells at their equators and also serve as a spacer between them.
The bottom end oi the inner shell is also dished downwardly as at 2| opposite the bung opening to provide a ilat area of considerable extent which may be securely welded to the bottom wall II of the outer shell. Thus the bottom half of the inner shell is ilrmly united to and braced upon the outer shell, but otherwise is generally spaced apart therefrom.
Provision for uniting the top half of the inner shell to the top half of the outer shell is as follows. Before assembling the inner and outer shells, a
steel ring 22 is welded to the under side of the top wall il, as is best illustrated in Figure 3. The upper half of the inner shell is formed with an upwardly'extending neck 2l which is, during the assembly of the inner and outer shells, welded securely to the ring 22 and the top wall I6, thus providing a firm union between the inner and outer shells at this plane and also providing a leakproof connection between them at that position. To add further strength to the outer shell a series of annular corrugations such as 24 may be provided in the upper and lower halves of that shell.
The top wall I6 is also preferably provided with a bushing 25 which may be welded in place as indicated and provided with a threaded plug 26 for sealing the same. Also the lower half of the outer shell in the vicinity of the bottom chime may be provided with a bushing 21 and a threaded plug 2l.
It should be noted that the flanges I9 and 20 are provided with elongated slots 28 in register with each other, as many of these slots being provided as is necessary to facilitate the circulation of a coolant between the inner and outer shells supplied through one of the bushings 25 or 21 and exhausted through the other, or perhaps merely contained between and sealed between the inner and outer shells. Even when no coolant is being employed, if the plugs 2B and 28 be in place a deadl air space of considerable insulation value is provided between the inner and outer shells.
Due to the fact that standardized equipment of various types is already in wide use throughout the beer manufacturing and dispensing industries, this barrel is designed to accommodate such equipment. For example, the opening 3| which I have provided in this barrel is intended to' accommodate standard tap pipes. However. equipmentl for filling beer barrels requires an opening of a larger diameter. corresponding to the diameter of the usual bung openings and lsuch an opening l2 is provided. Furthermore, as I prefer to use a removable flexible liner, the insertion and removal of that liner is facilitated by providing a still larger opening in the top of the barrel, and accordingly such an opening is provided within the neck 23 of the inner shell.
Ifhe removable liner maybe fabricated from various materials which are inert to the action -overlie a washer il. The liner is then clamped against the washer by means of a plurality of cap screws Il extending through the fixture 3l which may be a metal forging, casting or stamping, or is otherwise formed from metal or even from non-metallic material. Threaded apertures having been provided in the ring 22 to receive the threads oi the bolt, the neck of the liner is thus brought down into sealed relation with the top wall of the drum and the under surface of the fixture 31. The washer 25 is provided with a plurality of grooves Il constituting air passages extending radially outwardly from its inner to its outward edges, spaced apart at frequent intervals around its circumference, for the purpose of permitting the escape of air which might become trapped between the liner and the inner shell when the liner is being distended.
'I'he fixture 31 and upwardly extending collar Il provide the bung size opening 32. The top edge of this collar is provided with a peripheral flange 40 notched out at intervals to permit a cap member 4I having a cooperating interrupted flange 42 to be dropped down over the iianges of this collar through the interruptions in the flange 4l and thereafter rotated into a tight wedged position. It will be understood that the cooperating interrupted flanges on the cap and collar, as is customary in such assemblies, have tapered contacting surfaces so that rotation in one direction will wedge the cap downwardly upon the collar while rotation in the opposite direction will loosen it and permit its removal. A compressible gasket 43 will be provided between the collar and cap to seal the ioint.
In Figure 3, I have indicated a liner 44 which will preferably be of sprayed material in the nature of a coating inert to the action of beer which may be applied to the indicated surfaces oi this cap. Likewise a similar coating 45 may be applied as shown to the fixture 31.
The smallest size opening Il in the cap member 4I will be the size usually provided for the tap pipe used in the dispensing of beer, and during transportation and storage of this barrel may be closed with a plug of wood or some other suitable material. An interrupted ilange 46, best shown in Figures 2 and 3, should be provided on the cap 2| adjacent the opening 3 to facilitate the attachment of tap pipes or other fixtures which must be united thereto in sealed relation.
In Figure 4, which shows the fixture I1, cap 4l and other associated parts in an exploded view preliminary to assembly, the removable liner 33 is also shown in the act of being assembled into the barrel.. the dotted portions thereof indicating that it is compacted to a size permitting it to be inserted through the opening in the top of the drum, after which it may be expanded in any appropriate manner to lie snugly against the inner shell.
It will now be perceived that I have provided a new type of beer barrel and a method of forming the same including the inner and outer shells which can be drawn in four separate sections and thereafter united by welding in a simple and etiicient manner. While a removable liner such as 33 is preferred, yet I may also provide a sprayed coating for the inside surface of the inner shell, selecting some coating material which is inert to the beer and having other characteristics suitable for lapplication to and adhesion to the inner steel shell.
While the foregoing description and accompanying drawings illustrate a preferred manner of constructing the barrel in accordance with the present invention it should be understood that the invention comprehends variations and modifications differing from the enclosed embodiment, Without departing from the scope of the invention defined in the appended claims.
