GETTELMAN METAL BARREL Filed Feb. 4, 1955 2 Sheets-Sheet 2 ATTORNEYfi Patented Feb. 23, 1937 UNITED STATES PATENT OFFICE This invention relates to improvements in metal barrels.

It is the primary object of the invention to provide a barrel in which the chamber which receives the contents may be made of relatively light metal having a perfectly smooth interior suitably reinforced to permit of its handling without damage. and assured of sanitation by means which provides adequate'bung and tap bowl'flttings wholly outside, of the storage chamber and to either ofwhich-all portions of the storage chamber are readily drained; I j

More specifically stated, the purpose of the present invention is to provide a' relatively light metal chamber having protecting sleeves encircling and extending beyond its ends, and a girth band of concave form and cross section extend- 'ing about the largest diameter of the chamber to reinforce the same and to provide a space between the band and the chamber or shell in which a bung is received to be protected during handling of the barrel and to avoid interference with the free draining of its contents. 1

. Further objects of the invention are to provide a new and improved means for protecting a stampapplied to a barrel closure; to minimize the cost of manufacturing metal barrels by prog rolled about and easily manipulated.

may be made up of two separate end portions 1 welded together about a central line B, which 5 preferably represents'a larger diameterthan the diameter of the shell adjacent its heads 1;

The heads I .are preferably convex, so that all portions'of the shell 5 will drain toward any point thereof which happens to be lowermost. 10 This feature is of great advantage not only in emptying'the barrel, but particularly, in washing. Projecting beyond each'hea'd of the barrel at the ends thereof, is an annulus 8 conforming to the taper of the barrel and weldedjthereto at I. vEach annulus is preferably provided with a series of ports Ill so that when the barrel is standing on end any liquids tending to accumulate within the annulus 8 will be drained therefrom to protect the metal from corrosion. 1 The annuli 8 are preferably made of relativelyheavy metal as compared withthecontainer I. They are heavily beaded at H to withstand the hard usage encountered during the manipulation of the barrel in practice.v 1 i Fully protected by one of the annuli i is a tapped fitting I! which includes a sleeve l1 adapted to receive a stoppen II and flanged over at is to provide anchorage for a detachable cap 20. In the respect just described the fitting ll may be of any conventional type. In order to receive the government stamp, the fitting II is preferably provided with a rather K extensive planiform surface at 2| towhicha stamp or seal 22 may be applledover the cap 20 i and the stopper It. To protect the stamp while the barrel is in'transit it is preferred that the fitting ll be formed to provide tongues at 24 over which the apertured ends of an elastic protector 25 maybe engaged. The protector may 40 conveniently be made of rubber or elastic fabric.

' The same protecting means is claimedin my space is formed at 3] which is sufllcient to receive the inwardly tapered bung fitting 32. This bung;

fitting is of suflicient dimensions to receive and properly to hold a tapered bung plug 3! ofadequate size, without any projection of said bung beyond the girth band 38. The fitting is preferably shouldered outwardly at 34 to expose the end of the bung.

Together the band 30 and the annuli 8 comprise means for rigidly reinforcing and strengthening the shell which may consequently be made of relatively light material. If desired, the annuli I and the girth band 38 may be so extended as to contact each other and permit of a weld uniting these elements as shown at 85 in Fig. 3. Either construction permits the shell or container proper to be made of relatively thin and light-weight material, since the girth band 88 and the annuli 8 at the ends of the barrel are, in either case, so positioned as to take all shocks during the rolling and upending of the barrels. The girth band 48 not only protects the barrel but greatly facilitates the upending thereof.

It is particularly to be noted that the entire contents of the barrel may be withdrawn either through the tap fitting l5 or the bung fitting 32, upon withdrawal of the closure l8 or bung 33. As above noted, this feature not only effects economy of the contents of the barrel, but greatly promotes sanitation since it permits of the perfect drainage of the barrel in the washing thereof.

Because of the reinforcement provided as aforesaid, it is possible economically to make the container or shell 5 of light weight stainless steel or other similar non-corrodible metal. It is also possible to use ordinary iron and to tin the interior or apply any other protective coatin through the means disclosed in Fig'. 4.

A shaft 48 driven by pulley 4i carries a pair of arms 42 which support a tailstock 48 and a headstock 44 releasably engaged with the heads of the barrel. The headstock has a squared end 45 which may be engaged by a chuck 48 carried by a motor 41 or otherwise driven.

The coating material may be supplied from a tank 48 through a pipe 48 through the bun hole 82 of the barrel, after which the bung hole may be closed, the pipe 48 swung aside, and the barrel rotated end over end about the axis of shaft 40. In the course of this rotation the coating material will be fairly widely distributed over the inside of the barrel and the shaft 48 may then be brought to rest with the headstock 44 in alignment with chuck 48. The headstock may now be rotated to turn the barrel on its axis, thus centrifugally distributing the remainder of the coating about the interior side walls of the shell 5. Any surplus of coating material remaining in the barrel may be discharged on to trough 50 for delivery where desired.

An interesting feature of the above described mechanism consists in the fact that it enables the barrel to be tinned throughout its interior. The barrel is pickled" interiorly with the usual bath to prepare the surface for tinning. Instead of separately heating the barrel or immersing it in a tinning solution, I simply deliver to the barrel from reversoir 48 a suflicient quantity of hot tin so that the heat contained in the tin itself will raise the barrel to the proper temperature. The surplus tin will be drained out after the tumbling and centrifugal operations above described, and may be reheated and used in a subsequent tinning operation.

A further means of interiorly providing a metallic coating for the receptacle 5 involves the electroplating of the interior of the barrel by completely filling the receptacle with a. suitable electrolyte, introducing one electrode through the bung hole, and using the barrel as the other electrode in a circuit which will deposit metal from the electrolyte upon the interior of the barrel. As in the tinning process above described. this electrolytic method has the advantage of using the plating metal only where needed to protect the contents of the barrel without going to the expense of plating or coating the exterior.

In Figs. 5 and 6 I have shown a thermally insulated container which, in addition to the advantages of the constructions heretofore described, has the further advantage of protecting the contents of receptacle 5 from heat and cold. The construction is very similar to that above described except that the annuli 8 are made slightly larger in diameter than the annuli shown in Figs. 1 and 3, and are therefore spaced from receptacle 5 at all points. The inner margins of annuli 8 are welded at 8 to the girth band 88 and are spaced from the ends of receptacle 5 either by means of rings 52, as in Fig. 5, or by integral internally formed ribs 58, as in Fig. 6.

In either case the final weld 54 may, as a matter of convenience, be made by forming the annulus 8 with peripherally spaced slots 55 through which the welding material 54 extends to join the annulus 8 with the underlying surface.

False heads 56 are welded to annuli 8 and serve to complete an enclosure about the inner receptacle 5. The space within girth band 88 and annuli 8 in this form of construction is insulated either through the use of a suitable insulating material or by withdrawal of the air to produce such degree of vacuum as is practicable.

The construction shown in Figs. 5 and 6 retains all the advantages of the above described constructions so far as concerns clearance in which the bung hole and tap fittings may be located. Additionally, constructions shown in Figs. 5 and 6 have a relatively high degree of thermal insulation value.

Fig. '7 diagrammatically illustrates the electroplating method above referred to. It will be noted that a special bung 33' is equipped with an electrode 58 which extends toward the center of the barrel. The barrel is filled with electrolyte, and the electrode and the barrel are properly connected with the terminals of a plating circuit.
