To all whom may concern:

Be. it known that I, 'lsmisrwnbrlmo'ion Horse, a citizen of the United-S ates, residing at New'York, in the city ,a d county of New York,hav p invented certain new and useful Improvements in Metallic Casks or Barrels; and-I ddhereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it appertains to .make'and use the same.

1,-The particular object of the invention is teproyrde a metallic cask or barrel, capable of retaining a considerable gas-pressure, and serviceable as a delivery receptacle for gasc'ohtaining liquids, such as malt liquors,'or the like, and one which is also preferably provided with heat insulation, whereby it tends to maintain. the original temperature of its contents against changes from CODV8C-' tion and radiation. In the accompanying drawings, I have illustrated in three figures the preferred embodiment of my-inventiou', using the same reference characters to indlcate the same parts throughout.

F igurejl isacentralvertical section'of my improved cask or barrel;'Fi 2 is an end elevation,.and Fig. 3 isa sectional detail of the bung.

My improved barrel is characterized by 'the employment of a double metallic shell made up of an inner shell a and an outer shell b,'this double shell affording a light and cheap construction which may be given insulating properties either by packing the space between the two cylinders with a noncond'uctor-of heat such as asbestos or mineral wool, 'or the like, or by exhausting the air from the space between the two cylinders to create a partial vacuum therein. The

purpose would depend upon the limiting conditions arising from the diflicul'ty of cre- 'ating and maintaining the vacuum, as comparedwith the valve of the insulation thereby secured, and it will be apparent that the spacezbetu-centhetwo cylinders, even if filled with air, would afford a substantial insulation,

Inithe'particular formillustrated in the draw'ings,.'the barrel shape is produced b impartmga-slight bulge to the inner an outer shel1's,.tl 1e bulge being just enough so: that the inner shella. may ass through the ends of the outer shell 6 w en the parts of the barrel' arebmg assembled. It will be understood, however, that this particular degree of bulge is not an essential feature of the invention and may be modified to suit the requirements of any particular case, or

the inner and outer shells may assume a truly cylindrical form.

-The circular heads c and d of thebarrel,

which are preferably made of pressed steel,

are provided around their circumference with continuous right-angle return sections 6, preferably made integral with the head and merging into the circumferential portion thereof through a strengthened annular edge portion f. This strengthened annular edge portion 7 of the head is grooved as at g to receive the edge of the inner shell when the right angle return is placed over the outside thereof, as indicated in I the drawings and in assembling-the barrel the'inner shell is riveted to the inwardly extending flange of the right-angle return portion, as shown. and calking within the groove 9 isrese'rted to to ,make a gas tight joint. The inner shell carrying'the heads is secured to the outer s'hell, and the space between the two shells is closed, by annular channel hoops m and n, the inner leg of each of which takes over the outwardly extending flange of the right-angle return e and is anchored in an" annular groove 0 1n the upper surface ofthe strengthened annular edge portion f of the head, permitting calking at that point. The outer leg of each channel hoop overlaps the outer shell ahdmay conveniently be se cured thereto a'l bng their meeting lines by brazing, welding or otherwise; and for. 'greater security the bottom of the channel 1sv preferably provided with grooves, as shownin Fig. 1, to engage the upper edges of'the outwardly-extending flange of the rightangle return e,f and of the outer shell. In order to prevent an injurious attack upon.

the metal by the contents of the caskioriOO barrel, I line the inner shell with a neutral or insoluble rotecting glaze, as indicatedat p, and whici may be of any suitable material such as shellac or a silica glaze.

For the purpose .of giving access to the 105 interior of the cask or barrel to permit. repair of the lining-andthe like,.I formin 1; one of the heads-c, an opening closed by an interposed elpsure' g which is so c nstr cted.

.in place by a series-of seat of any known ing flange or tenon r, a gasket being interposed between the flange or touch and the bottom of the groove, The closure 9 is held blind-set countersunk screws t. This headc is also provided with a bung-hole 14 adapted to receive a bungconstruction. It will be observed that the closure 9 is so arranged that the internal pressure of the gases tends to close .it more 'tightly, but it may be removed to permit access to the'interior of the barrel by removing the screws}? and turning the closure within thebarrel so that the narrower portion of its elliptical section ma pass through the wider portion of the elliptical'opening-and thereby be withdrawn.

It is convenientto provide in the cask or barrel so constructed a double shell thereof, for purposes which will readily be understood, and to this end I proceed as follows, it being understood that the be located'in any convenient The bung-hole is formed by inter-posing three members in the shell,

these members being innerand outer thread ed sections 'v and w supported in alinement with one another and in engagement with the shells by the annular floating nut or union 0:. The threaded sections a and w are turned over at their opposite ends to infold the edges of the inner andouter shells, and the meeting ends of the sections are ground to accurate contact with each other when driven in on their threads to a meeting pointwithin the annular nut or union w.

The overturned end portions of the sections a) and w preferably have double annular shoulders asindicated at a" so that the innor shoulders seat against the floating union and the ed tween the inner shoulders and the ends of the said union.' In constructing the barrel the, threaded section 1) is placed within the inner shell and projecting therethrough, the annular nut is then screwed onto the threadedsection' until it seats against the shoulder thereon and the inner shell. Then after the outer shell has been put in place the outer section 11; is passed therethrough and tightly screwed into place within the union.

By this construction the sections 1) and 'w are accurately centere by the union, and, by virtue of the fact that their meeting ends are brought into contact with one another, they form a continuous bung-hole with a smooth bore and the screw threads are probnng-hole in the gesof the shells are anchored be- -tected 'from injury, by blows occurring when a spigot is inserted. Furthermore, in the preferred construction illustrated, a double ground joint is provided at each end of the union, onebetween the union and the inner shoulder on the member I; or :w, and

the other between the outer shoulder and the shell; and any necessity for accurately grinding the opening in the shell is avoided.
