SHEET-METAL vnssnn Specification of Letters Patent. Patgntgd Afi 29, 1922 Application filedJune 5, 1919. Serial'No. 302,019.,-

My invention is particularly applicable to sheet metal barrels, drums, and similar vessels, comprising cylindrical tubular shells having bottoms permanently secured therein,

and the object of my invention is to provide a rigid and durable chime and tight joint, at the junctions of such shells and bottoms.

As hereinafter described, an essential feature of my invention is the provision of a hollow ring over which the edges of the metal sheets respectively forming, such shells and bottoms are bent, and which ring primarily contains material which may be melted and flow into the joint to seal the latter. For instance, such sealing mate rial may be brass spelter and flux.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawing: Fig. I is a fragmentary, vertical sectional View of the lower end of a vessel embodying my improvement. 7

Fig. II is an inverted plan view of said vessel.

In said figures: 1 is a tubular shell, of circular form, which may be primarily cylindriform. 2 is a closure plate, forming a bottom or head in said vessel, which closure plate may primarily have a cylindriform perimetral flange. Said closure plate 2 is preferably of such size that it is necessary to force it into position in said shell 1, and said shell may have an annular internally projecting bead 3 serving as a stop determining the position to which said closure plate may be forced into said shell However, said bead may be omitted and said shell and closure plate be rigidly connected by spot welding them, electrically or otherwise, as indicated at 4 in Fig. I, so as to prevent accidental relative displace ment of said shell 1 and plate 2 during the subsquent bending operation, hereinafter described. The tube 6 may be primarily straight, but is bent to form a ring which is split both circumferentially, as indicated vlindrical form, and then bent to form a rin at 7, and transversely, as indicated at 8; the latter being-formed at the junctions of the ends of said tube 6. Such anannular tube 6 may be formed from a. primarily flat strip of sheet metal, which is first rolled to. cy-

However, it isto be understood that such a tubular ring may be, formed from a primarily flat annulus Jofsheet 'metalby a pressing operation, forming tubular ring which is endless.

In either case; the tubular ring Gmay be 'ohargedwith sealing material 9, which is primarily loose, as indicated by the dotted llIlQS 111 F 1g. I, and may for instance, comprise a mixture of brassspelter and flux, or other soldering or welding material.

Said tubular ring 6 having been forced into theposition shown in Fig. I; the free edges of said shell 1 and closure plate 2, may be rolledior otherwise bent-over said ring, to the position shown in Fig. I. There upon, the assembled structure may be heated until the sealing material 9, melting from said tube 6, fills all of the interstices of the joint, and seals the latter, as indicated in full lines in Fig. I; thus. forming'a vessel with a rigid chime and tight joint.

It is to be understood that if the vessel above described is to be used as a container for liquid or other material which may be readily introduced and removed therefrom through a hung or similar opening; both ends of said shell 1 may be provided with plates 2 permanently sealed therein as described. However, if a vessel having a plate, sealed as above described, is to be only temporarily closed at its upper end, any suitable temporary closure may be employed. For instance, a head may be formed with a reinforcing ring, such as the ring 6, but without permanent connection with the shell.

Of course, I do not desire to restrict myself to a vessel having a cylindrical shell as my invention above described is equally applicable to barrels and similar vessels of bilge or other forms.

Although I find'it convenient to make the closure plates 2 from ordinary flat sheet metal; if the vessel is to be subjected to internal pressure, or if it is desired to utilize all available space; such closure plates may be bulged outwardly, within the space formed by the chime aforesaid.

Therefore, I do not desire to limit myself an annular.

to the precise details of construction-andarrangement herein setv forth as; it is obvi ous that various modifications may be made therein, Without departing from the. essen-J; tial features of my invention, as defined in the appended claims.

I claim? 1. A sheet metal vesselcomprising an-- outer shell of circular form;a closure for the end of said-shell, comprising-n plate having a :flange fitted to said shell means limiting "the relative position of said shell and closure plate comprising "an inwardly: extendingwannular bead on said shell; a

reinforcing j ring v formed of a split sheet metal-tuhe fitted in-said closure plate; and" containing sealing. means; thewedges of said shell and closure plate being closed over said ring, and :said sealing-means filling edges and said rings 2. A sheet meta-l vessel comprislng an" outer-shell; a 'closurefor saidsheIljcOm -u prising a plate having a flange-fitted tosaid shell means 1 limitin -the relative --position 3. A sheet-metal-Wessel comprising an outer shell; a closure-for, said shell; 'comprising a plate'havin-ga flange fitted to said shell; a tubular reinforcing ring containing I fusible sealing means the-edges of said shell and closure plate overhanging said ring, and said sealing means seallng the joint be tween said shell and closure.

4-. Ash eet metal vessel comprising an outer shell? a closure for said shell comprising a plate having a flange fitted to said shell; a tubular reinforclng ring containing sealing means; the edges of'said shell and closure plate engaging said ring, and said sealin means sealing theoint between said shell and closure.

5. A'sheet' metal" vessel comprising. an outer shell; a closure for said shell, comprising a plate; a tubular reinforcing ring containing sealingmeans; and said sealing means sealing the joint between said shell and closure. the interstices at-the jo-int "between said 6." An article of manufacture, comprising a "tubular-"sheet steel 'ring containingtusilole -sea'ling means; including hrassspel'ter and a flux, and having a venti'or said sealingmeans;

7. An article of"1nanu-facture including a hollow metal ring containing fusible seal, 1ng 'means, and "having a :vent "for said 'n1eans';and closure plate connected With said ring'by said sealing means.
