` SHIPPING AND STORING RECEPTACLE Filed April 28, 1934 2 Sheets-Sheet 2 Patented Nov. 17, 1936 :PATIENT OFFICE SHIBPING AND .STOEING :RECEPTACLE Walter Kline, Wellington and William A. 'Brubaker, Akron, Ohio; `said Kline assignor to Ethel H. `Morrison, `Wellingtonl Ohio Application April-28, 19331,:ScriaLNo. 7223996 The present vinvention relates in general lto vshipping'and storing receptacles and has par- .'ticular :reference to -a 'receptacle of this kind in which a spaced wall or jacket -is employed for insulating or otherwise protecting the contents of .the innerl container.

Among ,the objectsof the invention is to provide a receptacle which may be used for stor- .ing or shipping solids or liquids while maintaining :them in an7 insulated condition so that desired temperatures of 'the vsame may be substantially xmaintained.

-In ithe accompanying drawings in Which-several embodiments of the invention-are illustrated .Figure 1 is aview in -sideelevation. and ,partlyin section of a barrel showingone formof rthe invention.

Figure 2 is la similar 4view of a barrel-showing l'another form of the invention.

iReferring'to the form of' the invention shown in Figure l, 5 represents an inner non-corrosive container which is housed within and spaced from an outer metallic shell 6. The assembly-is arrangedto leave .-a lspace VI between :theginner container'5- and the shell and this space is vadapted to contain an insulating medium'such as cork or `any other material .suitable for the purpose.I Since we intend that the barrel shown inFigure V1.beused.for shipping and storing liquids, as for .example beeigait isl necessary that thezinnerfcon- :tainer .5 be properly supported within therouter fshellfl `so as to ylorestallithe possibility "of :breakage orfot-her damage. Toithis endit isiproposed fto suspend the container in rubber or otherlike aresilientslings, :so to speak. This typefofs-.sus- :pension for-.the receptacle '5 e is lpreferably yac- ;counted rvfor .by rubber bands :or ribs-*8 ywhichenzcircle the .circumference :of fthe vreceptacle :5 aat :spaced intervals. `For all practical purposes ytwo of these bands will be sufficient, however, more may be usedif occasion demands. The thickness of the'bandsj correspondsto the thickness of the space 'I between the inner and outer receptacles and the bands are preferably held in place by means of circumferential shoulders 9 which are moulded on the container 5 at the locations where the bands are to encircle the container. Since the container 5 is barrel shaped, that is to say tapering towards its ends, it Will be necessary to form one shoulder only for each band. The bands are further held in place by. impinging against the inside wall of the outer shell 6.

In addition to the supporting bands 8 we also employ rubber end cushions which are preferably fashioned as circular plates I0. These plates .are ,moulded or otherwise formed .with central 'countersunk areas :to'leave a rim II of va ysubstantial thickness of rubber. The ends of the .inner container i5 are concave and are formed with hub-like offsets I2 which occupy the countersunkfareasfontheinside of the supportingplates .IIL aThe end walls of the outer shell .6 are stamped or otherwise formed withhubs I3 which occupy the :opposite acountersunk areas of the plates. .In this way it ,will be seen that not only A.are the `plates .held in ,position` at'the barrel ends but the inner :container 5 is ldeinitely suspended byftheplates as a result of the hubs I2 occupying the countersunk areas of the `plates andthe rims III `ofitheplates :embracing the shoulders :provided byfthehubs I2. In this way We areeniabledto present a vsubstantial'thickness of rubber -zor other-shock absorbing material at the ends` of the container;5-so that'any jars or blows delivered ".to the =she`ll,.occasioned by handling of the barrrel, will'beabsorbed in such a manner as to pre- .vent injurygto-the container.y

It should be Aalso;brought vout here that the manner of suspending :the'container 5 will not ionly properly absorbblows-on the end ofthe bar- 'rel but jars korvblows which may be imparted in :anylocation lon thessurface of the barrel.

'InJ order to house the inner container 5 within the outershell ,6 in a convenient and practical manner'we `propose lto construct the shell 6 in at least two sections in addition to the separately -formed ends -I4. ,The ends I4 are made with .flangedrims I5 so that when the ends are set fin the-shell they may be welded or otherwisefixed lto the shell. Wet-havefjustumentioned"we propose to divide the esamefintermeiiiate itsends as at I6, so that the Alllingopening isintersected along the line of division. Tomake :1a-convenient assembly of the sections-:.we'propose to Ause an overlap which may :be sealedby .Welding-as'an example. In orderto :'add'frigidity to :the l:shell 1 6 we `have in' mind corrugating the same to leave offset ribs Il in its thickness. As many of these ribs may be used as considered necessary. For the purpose of illustration we have shown only two and located the same on opposite sides of the filling opening.

In providing for the lling opening we prefer to employ a metallic sleeve I8 having a substantially heavy flange I9 which overlies the upstanding and separately formed disk-like cover plate 20. This cover plate is circular in shape and is adapted to cover the relatively large opening which is left in the shell 6 around the area in which the filling opening is assembled. This In making the shell in sections asv cover plate may be welded or otherwise attached to the shell 6 as at 2|. To reinforce the lling opening it is preferred to employ a bushing 22 which snugly fits the sleeve I8 with its anged periphery 23 bearing against the underside of the flange I9 and also bearing against the end of the cover plate 20. The thickness of the container around the filling opening is materially increased as indicated at 24. In providing for this reinforcement it is to be noted that the flange 23 of the bushing 22 embraces the increased thickness 24 so as to provide for a substantial water-tight fit and also preventl any breakage from occurring at this locality. In providing this filling opening and assembling the parts we have taken into account the necessity of providing for sufficient give in order to compensate for the resiliency of the suspension for the container. In other words while this give,

so to speak, occurs only in a limited degree itV has to be taken into account and the peculiar manner of assembling the filling opening is of particular advantage. It is of course understood that the filling opening is adapted to receive a plug or bung.

The form shown in Figure 2 while embracing characteristic features of the form shown in Figure 1 is somewhat modified in that provision is made for a vacuum space. This space is provided for as at 25 between the container 5 and the outer shell 6. In addition to this vacuum space 25 the outer shell 6 is fashioned with spaced inner and outer walls 26 and 21. The space between the walls 26 and 21 will contain an insulating material preferably an asphaltum or the like composition. We have found that a material suitable for this purpose may be realized by a mixture of asphalt, latex and rosin in suitable proportions. This material when in a uid or semi-fluid condition may be poured, blown or otherwise caused to fill the space between the walls 26 and 21 so as to completely enclose the inner container 5 in an insulated jacket. It is of course understood that the ends 28 of the barrel seal the insulating space. A welding operation will be suitable for this purpose. The outer shell 6 of this barrel is made in sections like the shell 6 in Figure 1. Owing to the double wall structure it is necessary to make two overlapped connections 29 instead of the single nt I6 of Figure 1.

Additional modifications may be noted in Fig. 2 in that the separately formed inside end 30, which is welded as at 3| to the inside wall of the shell, is made with an inset 32 to support the rubber cushion 33 otherwise the rubber suspension is the same as in Figure 1. Still another modiiication occurs in the manner of terminating the inner wall 21 of the shell. The inside end of this wall is curved around the rubber band or rib 34 and bears against the surface of the v container 5. As a result of this operation the in the quantity of the asphalt material serve to cushion the assembly at the filling opening, but

it also provides an ample seal for completely sealing the vacuum space 25. In other respects the -iilling opening is made identical with the form shown in Figure 1 and therefore carries the same reference numerals.

In order to draw a vacuum within the space 25 we prefer to provide a suitable valve 31. This valve is made to accommodate a needle-like instrument which pierces the self-healing material contained in the valve. There will be an opening in the end wall 28 of the shell as at 38 which is in line with an opening 39 in the valve communicating with the vacuum space. The needle is extended through the opening 38 and the opening 39 and may be used for drawing the vacuum in the space 25, when it is pulled out the selfhealing material in the valve will close the opening 39 and the asphalt composition contained in the space between the inner and outer walls of the shell will close` the opening 38.

From the above explanation it will be readily seen that we have provided means for protecting various kinds of liquids or solids While they are being shipped or stored and aside from these qualities it should also be noted that we have provided away for handling liquids in a very sanitary manner and one in which the containerfor the liquids may be very easily washed or iiushed out.

While we have shown only two ways that the invention may be reduced to practice we wish it to be understood that the showing is simply illustrative and it should not be considered that the invention is confined to this particular showing except where the scope of the subjoined claim makes such interpretation necessary.

Having thus described and shown an embodiment of this invention, what we claim and desire to secure by Letters Patent of the United States is:

A spaced wall receptacle, comprising an outer metallic'shell, a container within said shell and means for supporting and cushioning said container in spaced relation to the shell comprising bands of resilient material encircling the containerand snugly fitting the space between the shell and container and end cushions of resilient material spacing the ends of the container from the ends of the shell, said end cushions having opposed counter-sunk areas and outwardly oifset portions on the shell and container occupying said areas.
