HEAD FOR SHIPPING DRUMS.

Application filed April 16, 1927. SerialNo. 184,256.

This invention relates broadly to metallic shipping drums, and more specifically to a head and removable cover for such drums.

The primary object of the inventlon is to provide a sheet metal barrel OI" dlllII1-l1k8 container of a type commonly employed for one-time use in shipping heavy materlal, as-

powdered calcium carbide, the same having a head and slip cover construction adapted to withstand the usual shocks and jars incident to rough handling wlthout rupture at the joints and without danger of thecover becoming so dislod ed or unseated as to permit leakage, or s ifting, of the contents of the barrel.

A further object is to provide a head and cover structure of the character mentioned embodying means whereby much of the force of shocks to which it is subjected 1s e ffectually absorbed without injury to the o nts.

In describing the invention in detall, reference is herein had to the accompanying drawings,in which Figure 1 is a head-end elevation of a drum embodying my invention;

Figure 2 1s a section on line 2-2, Fig. 13

Figure 3 is an enlarged detail section on line 3-3, Fig. 1.-

Referring to said draw1ngs, 1 designates the body of a drum or barrel-like contalner of the general character employed 1n making one-time shipments of materials and ordinarily made of light-gauge sheet. metal. Attached to one end of the body'l in any appropriate manner, as by the lock-seam 2 shown in the drawings, is a sheet metalhead 3 having therein'a central opening des gned for the reception of a removable closure 4 of the slip-cover type, said opening being defined by an upwardly extending flange 5 which is designed to' receive the closure 4 in snugly sea-ted relation thereto.

The flange 5 is constituted by an exten The upper edge portion 5 of the flange 5 is turned outwardly into partially over hanging relation to the upwardly facing channel which is formed by the provision of the bead 6, thereby forming a seat for the reception of a gasket 8.

The closure or coverv i has an upright annular Wall 9 which seats snugly within the embrace of the head flange 5 and which has its upper edge portion or extremity curved outward to form a roll-like terminal 9 for seating upon the seated gasket 8. Tongues 10 are formed at suitably spaced intervals on the edge 5* of the flange 5, the same being adapted to be bent inward into seated relation to the terminal roll 9 for securing the cover in its properly seated position in compressing relation to the interposed gasket.

Formed in the head 3 directly adjacent to the seam 2 is an upwardly pressed bead 11 which is designed to render the head yield able relative to the seam under shocks to which the container is subjected, thereby to terminal IOll thereof acts to compress the gasket into sealing relation to the joint between said cover and the head 3. Moreover, it will be apparent that the flangefi and the'therewith associated double, or reverse, bead formation of the head provide an especially resilient construction'adaptcd to absorb impacts or shocks incident to forcible shifting of the contents of the drum against the head and cover which would otherwise tend either to rupture the head or to so distort the latter as to permit leakage at the joint.

What is claimed is 1. A sheet me-tal'cont-aine-r having a head formed with a central circular opening de-' fined by an upstanding flange, said head having therein a downwardly pressed bead of'whichthe inner wall is extended to form said flange, said head also having therein an brace of said flange, and tongues formed on said flange for bending inwardly into retaining relation to said cover.

2. A sheet metal container having a head formed with a central circular opening defined by an upstanding flange, said head having therein a downwardly pressed bead of which the inner wall is extended to form said flange, said flange having its terminal edge portion turned outwardly into overhanging relation to said bead to form a seat for a gasket, said head also having therein an upwardly pressed bead disposed in closely encircling relation to the," downwardly pressed bead, a slip cover having an upright annular flange for seating within the em brace of said head flange and provided with a terminal edge portion turned outwardly into overhanging relation to said gasket seat, and tongues formed on said head flange adapted to be turned inwardly into seated relation to said terminal edge portion of the cover flange, the reversely disposed beads cooperating to render that portion of the head adjacentto the cover readily resilient for absorbing impacts and preventing rupture of the joint between the head flange and the cover.

3. A sheet metal container comprising a body, a head attached peripherally to said body and having therein a central circular opening, an upstanding flange defining said opening and having its terminal edge portion inclined outward to form a gasket seat, tongues borne by said edge port-ion at spaced intervals, said head having therein a downwardly pressed circular bead and a closely adjacent encircling upwardly pressed bead, the inner wall of the downwardly pressed bead having said flange formed as a continuation thereof, and the adjacent walls of said beads combining to form a compound curvature, and a removable slip cover fitted within said opening, said cover having an upright flange received snugly within the embrace of said head flange and terminating in an outwardly turned portion which overhangs said gasket seat, said tongues being adapted for turning into seated relation to said outwardly turned port-ion of the cover flange.

4. A sheet metal container comprising a body, a head attached to said body through the provision of a seam, said head having an upwardly pressed bead formed therein closely adjacent to said seam, said head being provided with a circular opening defined by an upstanding flange and having therein a downwardly pressed bead of which the inner wall is extended to form said flange, said flange having its terminal edge portion inclined outwardly to form a seat for a gasket, a slip cover having an upright annular flange fitted within the embrace of c said head flange and provided with a terminal portion which overhangs said seatfor resting upon a gasket supported by the latter, and means whereby said cover is se-i cured in its seated closing position.

5. A sheet metalcontainer comprising a body, ahead attached to said body through the provision of a seam, said head having' an upwardly pressed bead formed therein closely adjacent to said seam, said head being provided with a circular opening defined by an upstanding flange and having therein a downwardly pressed bead of which the inner wall is extended to form said flange, said flange having its terminal edge portion inclined outwardly to form a seat for a gasket, a slip cover having an upright annular flange fitted Within the embrace of said head flange and provided with a terminal portion which overhangs said seat for resting upon a gasket borne by said seat, and a plurality of tongues formed upon said terminal edge portion of the head flange and adapted for turning into overlying seated relation to the terminal portion of said cover flange. In testimony whereof, ll affix my signature. 7
