SHIPPING AND/OR STORING RECEPTACLE Fiied oct. 9, 1934 lil Patented Non i?, i936 orties snierinc ann/on sronine nirenr'racnn -l/Jalter Kline, Wellington, William iii. l'rubaiser, Aileron, @him said Kline assigner to Ethel Morrison, tieilington, @hic [application @ctober ii, i934. Serial No. 'liil ii crains. (ci. 22oici The present invention relates ingeneral to shipping and/or storing receptacles` and. has particular reference to a vessel or container for liquids and in which any such material to be shipped or stored is subjected to the sanitary and other desirable conditions which prevail when a glass or other non-corrosive material is used as the shipping or storing receptacle.

One of the important features of the invention resides in the provision of means for protecting a glass or other fragile vessel whenrin transit or when stored so that the ordinary abuse to which the receptacle is subjected will not injure or otherwise destroy the same.

Another feature of the invention resides in the construction of a glass or other non-corrosive vessel which is adapted to contain materials for storing or shipping purposes and 'in which the materials are contained 'within such a vessel in an insulated condition so that changes in ternperature will not necessarily aii'ect the qualities of the stored material, at least to the extent that such changes in temperature as may be expected under ordinary shipping and storing conditions will necessarily mairea change in the condition oi the material. in this connection we are particularly referring to the shipping and storing of beer or other such liquid wherein it is desirable to maintain the liquid at more or less constant temperature between the time it is barrelled and dispensed. 'Aside from the instance related in the invention of the container we also havein mind the provision of a vessel which may be well adapted for use in transporting acid or any other such material which requires the use of a nonmetallic container such as glass or other noncorrosive material which is unaected by contact with certain acids. Due to the fragile qualities of such a container it becomes necessary to protect the saine against ordinary handling abuses and it is thereiore another object o the invention to construct a shipping and storing vessel in a manner to realize these advantages without increasing the cost of construction to a prohibited extent. I

With these and other objects in view, which will be apparent trom the following detailed description of the accompanying drawings we will now proceed to describe the construction oi' the invention with reference to' the illustrative ern bodiment shown in the accompanying drawings.

in said drawings:

Fig. l is a view in longitudinal section of a barrel keg or the like which is especially adapted for the purpose of containing beer or other such liquid;

Fig. 2 is a view in end section oi such a barrel; Fig. 3 is a view in cross section of such a barrel as shown in Fig. 1; and

Fig. i is a detailed view of a modification of the barrel shown in Fig. l.

Referring now to the drawings in detail and ywith. particular reference to the barrel or keg construction shown in Figs. 1-to 4, inclusive, 5 represents an inner container which is formed of glass or other non-corrosive material. In view of the fragile structure of this container it becomes necessary to protect the saine and with this end in view we propose to'house it within an outer metallic shell i5.

So far as the barrel or keg is concerned we propose to fabricate the outer shell t of sheet metal using an asbestos liner l in combination with the outer shell. The outer shell being formed of sheet metal may be easily fashioned with corrugated ribs ii and 9 of different diameters and which extend completely around the circumference of the shell in spaced relation, as best shown in Fig. i. These ribs are provided ior the purpose of strengthening the shell as well as to serve as raised areas upon which the barrel may be rolledI and which also act in the capacity ci bumpers or buffers to prevent the shell from collapsing when the barrel is dropped on a hard surface as may be expected when the barrel is being handled in transportation or otherwise moved from place to place.

it is also to be noted that these raised areas particularly the larger ribs t are ofiset outwardly relatively to the bung or filling opening in the side o the barrel. In this way the bung or nlling opening is thus protected against injury. The ends of the barrel are lllrewise equipped to withstand shoclrs by means of a circular hollow rirn iii. Both ends of the barrel being thus4 equipped with this rim add rigldity to the barrel ends and enables the saine to withstand the more or less rough handling and also oiiers an A discs II are welded or otherwise fixed to the ribs I0.

Since a bung is arranged. for one end of the barrel the construction of the discs II at one end of the barrel is modified to accommodate the bung. However, so far as concerns the disc at the opposite end of the barrel attention is called to the fact that it is a continuous plate having al central offset portion I2 with a stepped diameteras at I3 to accommodate the circular rubber cushion I4 which supports and cushions the receptacle 5. The opposite disc I I is substantially the same except that the oii'set portion or area I2 is made with a central opening to accommodate the bung.

In order to suspend or support the inner noncorrosive receptacle 5 so as to avoid injury or destruction of the same we propose to employ, in addition to the rubber end cushions I4, a centrally disposed cushion I5 which may be constructed of rubber or other suitable resilient material. This central cushion I5 as best shown in Fig. 3 will extend around the outer circumference of the inner receptacle 5 with its ends terminating in opposed relation at the side bung or filling opening.

The end cushions I4 which are rings are conned on seats made by the steps in the end discs II and embrace outwardly oil'set shoulders I6 which are fashioned on the ends of the inner receptacle 5. In this way the cushions I4 are confined in position to support the more or less fragile inner receptacle and asthus supported in cooperation with the center cushion I5 shocks under which the barrel is subjected will be absorbed to the extent of avoiding injury to the receptacle 5.

In addition to these shock absorbing features as realized bythe cushions I4 and I5 we also enclose the receptacle 5 with a plastic covering II. In practice we have found that this plastic covering can best be realized when we employ a bituminous or like composition. In selecting this material we have in mind the insulating qualities which may be realized as well as the shock absorbing qualities of such a. material. serve this purpose may be realized by a mixture of asphaltum with a certain amount of latex and rosin added in proportions which will maintain the desired plastic qualities with a consistency thick enough to prevent the same from flowing under ordinary temperatures after .the receptacle has been thus coated. The receptacle being coated with this composition is not only protected against shock but suitably insulated as well, so that the contents of the container is insulated againsttemperature changes which is desirable in handling beer and other more or less perishable liquids. That is to say, liquids which are apt to have their qualities changed by temperature variations.

As a further means of protecting the inner container 5 as well as to retain the bituminous coating I1 we cover the coating with a snug fitting jacket I1 of sheet material, preferably sheet metal. This jacket may be fabricated in sections, or in any other manner suitable for the purpose, the idea being to enclose as much of the container as possible, taking into account the openings made necessary by the bung ttings and resilient supports for the container.

To further insulate vthe receptacle 5 we also propose to employ 'ai material for the liner 'I I An asphalt composition which may well which is known for its insulating properties such for instance as asbestos. This liner 1 isfmade to approximately conform to the sides of the barrel with end portions in the form of discs having central openings which engage the end cushions I4 with their outer peripheries joining with the side portions of the liner. The ends of the side portions of the liner bear against the end discs II and the liner is, of course, made in divided sections to accommodate the central cushion I5 and the side bung structure. When thus constructed it will be seen that a dead air space is left between the coated outer surface ofthe receptacle 5 and the liner 1. While the air isnot evacuated from this space to leave a vacuum the space does serve as an added insulation and cooperates with theliner and the coating I 'I to add to the insulated qualities of the arrangement. f f

Referring now to the bung or iilling openings we have shown such an arrangementl in both the side and end of the barrel. We have shownthe bung in the side andthe end in the present showing to illustrate how it would be possible to provide for the bung in either location or in both locations if desirable. In providing for the side bung we propose to fashion the inner receptacle 5 with an increase in its thickness as at I8. 'Ihis increase in thickness is formed in the area immediately surrounding the opening. The inner walls of this opening being of considerable depth due to the increase in thickness I3 are rounded oil' as shown to accommodate a relatively thick gasket I9 made of rubber or other more or less readily pliable material. This gasket I9 is made with an annular depression around the same to fit the opening in the receptacle 5 and in order to make a tight closure as wellwas to provide for a bung opening Wev propose to employ a valve like disc 20 which is seated-on the inside of the gasket I9 having an upstanding interiorly threaded sleeve to receive the headed bolt like plug 2 I. 'I'he head of the bolt like plug 2I bears against a metallic cup 22 which is seated in the hollow portion of the gasket I9. which the head of the bolt 2| is especially fitted, the bolt may be turned to draw the disc 20 and the cup against the inside and outside of the gasket causing the same to wedge itself tightly in the bung opening and'make a perfectly tight closure. In this connection attention is called to the overlapping portions of the receptacle around the inside and outside of the opening.

In addition to this bung construction we also employ a ring 23 to reenforce the opening. The flange of the'ring 23 is made with a slot to receive the outer shell 5 and the depending flange on the ring is dovetailed in the annular undercut slot in the thickness I8 around the bung opening. The ring 2,3 encircles the outer portion of the gasket I9 and thus protects the same as well as protecting the thickness Il of the inner receptacle around the bung opening. 'Ihe inner liner 'I bears against the depending' flange on the ring 23 and rests upon the shoulder, on the thickness I8 in which the flange is dovetailed.

The construction of the end bung is modied to the extent that, a different type of closure is employed. A gasket 24 is utilized which corresponds substantially to the gasket I9. However, instead of employing the ring 23 the end disc II is seated in an annular slot in the gasket. A sleeve 25 is fitted in the gasket having a flange 26 on the outside and a threaded inner end 21.

By using a Spanner wrench, for

plug.- The internal head 3| of the center projection 30 is made to accomodate a special wrench such asa Spanner which engages the notches 32 (see Fig. 2). The flange 26 is also fitted with openings 33 to accommodate a wrench so that the nut 28 may be held and the sleeve 25 turned or vice versa which will develop a wedging eiect to cause the gasket 24 to tightly impinge in the Vopening made to receive it and thus make aproper closure. A washer 34 may be employed on the outside of the gasket under the ilange 26. It will thus be seen that either arrangement of bung tting may directly engage with the inner receptacle without injuring the receptacle and at the same time provide a perfectly tight fit to prevent leakage.

In Fig. 4 we have shown how `it is possible to use pneumatic protectors on the inside of the ribs 8. Each of these pneumatic protectors may be equipped with valves 35 for inflating the same with air. Thespace between the bottom and the shell will be filled with the asphalt composition as clearly indicated.

Any suitable closure for the mouth of the carboy may be used. Since this is the case we have not considered it necessary to illustrate any particular type.

Where we have used the words glass or nonf corrosive as a descriptive term for explaining the nature and physical properties of the inner container 5 it should be understood that `We have in mind using not only glass but also pottery or other ceramic materials, enamel ware or even st-ainless steel. It is therefore pointed out that when we speak of non-corrosive material in the description and claims we wish the'same to be interpreted as any material suitable for the purpose having the qualities described.

By way of further explanation we wish it to be made clear that we consider it of importance under some conditions of use to take advantage of the resilient properties of the pneumatic protectors or buers shown in Fig'. 4. As another means of realizing these resilient advantages We can apply a rubber covering upon the ribs 8 and also apply a rubber ring around the edge of theV By making these rubber coverings l Having thus described an embodiment of -our invention Awhat we claim and wish to secure by Letters Patent of the United States is:
