July 15, 1930. c. H. ROLLAS'ON' 07 7 REMOVABLE COVER FOR SHEET METAL CONTAINERS Filed Dec. 29, 1928 HTTDRNEY Patented July 15, 1930 warren s'rarss PATENT QFFECECI CHARLES H. nottason, or wnnnmne, WEST VIRGINIA, assrenoa 'ro wnnnmne STEEL CORPORATION, OF WHEELING, VIEST VIRGINIA, A CORPORATION OF DELA- WARE REMOVABLE COVER FOR SHEE'IEMETAL CONTAINERS Application filed December 29, 1328. Serial No. 329,120.

This invention relates broadly to sheet metal barrels or drums, and more particularly to a removable cover for the heads of such containers.

The primary object of the invention is to provide a drum having a removable cover and provided with novel and practicable means for securing said cover in place. i

Another object is to provide, in a device of the character mentioned, a head and cover construction having associated therewith attaching means which may readily be rendered operative by means of a hammer.

Still another object is to provide a device of the character mentioned which may be sealed so as to indicate unauthorized access to or tampering with the contents of the Figure 1 is a top plan view of a commercial form of sheet metal drum having a head and cover constructed in accordance with my invention; V V

Fig. 2 is a vertical section of the same;

Fig 3 is a fragmentary section on line 33, Fig.

Figures 4, 6 and 8 are fragmentary top plan views showing modifications of my invention; and y Figs. 5, 7 and 9 are vertical sections on lines 55 of Fig. 4, 7-7 of Fig. 6, and 9-9 of Fig. 8, respectively.

In said drawings, the numeral 1 indicates the body of a sheet metal container or drum and 2 the head for the same, said body and head being attached together, as by the usual double seam, as shown at 3. Said head has therein a circular opening 4 through which the contents may be introduced and removed, and defining said opening is an upstanding flange 5 which may have its terminal edge turned outwardly and downwardly, as shown at 6.

The opening 4 is closed by adisk-like sheet metal cover 7 which hasthereinan upwardly pressed circular rib 8 presenting a downwardly facing channel adapted to receive therein the upstanding flange 5 of the head.

In order to seal said opening, a rubber or cork gasket10 is inserted between the head and cover, as within the channel of the rib 8.

Attached to the head, as by welding, in" terinediate the seam 3 and the'flange 5 are the oppositely disposed foot'po'rtionsll of a pluj rality of vertically disposed sheet metal tongues 11 which, whenthe cover 7 is placed upon said head, protrude through slits 12 provided in the adyacent portions of said cover in'registering relation tOSfl-ld tongues.

Said tongues are formed by doubling upon itself the metal between said'foot portions, as

shown. 'Said slits are preferably reinforced by having their edges outwardly beaded, as indicated at 13. After said cover is placed upon said head with the'tongues 11 protruding through the slits 12, as aforesaid, it is secured in. place by bending the protruding tongues 11 laterally overthe beads 13 of said slits, as shown in dotted lines in Fig. 3.

It is preferred that in forming the head it be pressedinwardly, as shown, toa suliicient depth that no-part of the head structure, when assembled and fastened, will extend beyond the upper extremities of the seam 3, so that said head structure will be less liable to injury from rough handling of the drum.

In the modification shown in Figs. 4 and 5, the tongues 11 instead of being formedof a doubled strip of sheet metal, are formed of wire 1n the shape of a loop and the term]- nals of the wire are turned in opposite directions to form foot portions which are welded tolthe head 2; and, when'the cover 7 is in place, said loop maybe bent laterally over the adjacent bead13, as shown in dotted lines in Fig. 4;

In the modifications illustrated in Figs. 6 to 9, inclusive, an open wire ring 1a is passed through the eyes formedin the tongues 11" and 11', respectively, and has its ends secured to each other by a seal (not shown) after which said loops are flattened upon the cover, as shown in dotted lines in Figs. 7 and 9, as by means of a hammer, to secure the cover tightly in place. As will be under- I stood, the condition'of the seal of the wire ring will readily reveal to a receiver of a transported or stored drum Whether the cover has been removed after sealing.

What is claimed is 1. A sheet metal drum having a head with an opening provided therein, said opening being defined by an upstanding flange, a cover for said opening having formed therein a channel adapted to rece'ivesaid flange, a seating gasket received Within said channel, said cover having an annular horizontal flange having therein a series of slits, and means for reniovably securing said cover to said head, said means comprising tongues carried'hy said head and adapted to protrude through said slits and to'be bent downward into binding relation to said cover.

2. A sheet metal drum having a head with an opening provided therein, said opening being defined by an upstanding ih-nige, a plurali-ty of upright members carried by said head, a cover for said head having a channel formed therein designed to register with said flange and having a horizontal annular flange, a gasket received'within said channel, 7

said cover also having slits formed in its flange in registering relation to said upright members so that when said cover is placed upon said head said members will protrude through said slits and may thereupon be bent downwardly over said cover for securing the latter in seated relation to said head.

3. In a sheet metal drum having a head with an opening therein, a cover for said openinghavi'ngan annular portion which occupies seated relation to sail head and which has therein a plurality oi apertures, and members carried by said headin'protruding relation to said apertures, said members being adapted to have their protruding ends severally interengaged for preventing Withdrawal or" the cover.

at. In a sheet metal drum having a head with an opening therein, a cover for said opening having an annular portion which occupies seated relation to said head and which has therein a plurality of apertures, and upright members carriedby said head in protruding relation to said apertures, said members being adapted to have their protruding ends severally interengaged with said annular portion of the cover for preventing Withdrawal of the latter. 7

In testimony whereof, I afiix my signature.
