This invention relates to removable closures for receptacles and particularly to sheet metal barrels or drums used as shipping or storage containers. When such receptacles removable closures be provided with locking means for securely locking vsaid closures in closed position so that accidental displacement thereof can not occur in the handling and transportation of the receptacle, while for storage it is desirable to provide locking means which, whilemaintaining the closure in securely locked position, may be readily manipulated to permit the closure to be easily removed at will. A

The principal object of the ypresent invention is to provide a' new andimproved construction of a receptacle closure including a plurality of locking means adapted to be 'interchangeably used to fulfill the above requirements. A further object is to so construct the closure and the locking means therefor that danger of leakage about the points of connection of the locking means to the closure is prevented. Otherfobjects will appear more fully from the following more detailed description and' by reference to the accompanying drawings, showing various illustrative examples of my invention. In said drawings, Fig. 1 is a. fra menvertical section of a receptacle c osure ta anldlra locking ring therefor; Figr 2 is a fragmentary plan view of the cover shown in Fig. .1 showing a different construction of the closure seating members 'and illustrating the manner in which a pivoted locking means may be Y interchangeably used, Fig. 3 is a view similar to Fig. 1 showing-an application of my invention to a ldifferent form of cover seating ringhand Fig. 4 is a view similar to Fig. 1A

showing a slightly modified form of the pivoted locking means.

As shown in Fig.` l,the receptacle A has its side wall portion bent to form a'lap joint 11 with a sheet metal supporting ring 12, s'aidring forming a support for a cover seating ring 13. The latter, in the example shown, is channel-shaped in cross section, the lower flange 14 of the channel, in the illustrated example, extending inwardly beyond the upper flange 15 thereof. The inner edge of the supportingy ring 12 is bent backwardly about the inner edge of the'lower flange 14, said supporting ring 12 cooperating with the horizontal flange 16 of an outer reinforcing ring 17 to hold the cover seating ring 13 securely in position.'

' The cover 18 is preferably constructed ol' two sheets 19 and 20 spaced from'each other to form a chamber 19a and connected together adjacent to their outer edges by any suitable means such as a lap joint, the outer periphery of the cover being formed to provide a horizontally extending marginal flange 21, the arrangement being such that at least one of said sheets is shaped to forni an annular flange 22 depending from the inner edge of' the marginal flange 2l. ll desired, a protective annular flange .23 may surround and project below the flange 22, said flange 23 in such case being fastened in place by the aforesaid lap joint. When the PATENT y OFFICE.

fil

cover is in position on the, receptacle. the

vertically extending flange 25 of a locking ring 26 is adapted to be engaged. The locking ring 26 isof angular cross section and has a. horizontal flange 26a which is adapted to be inserted under the upper flange 15 of the cover seating ring and serves tohold the marginal flange 21 ofi the cover pressed tightly against a packing 27 which rests up' on the lower flange -14 of .the vcover seatingl ring 13. The locking ring26 is split at any suitable point of its circumference and is adapted to be forced into locked position, to hold the cover lsecurely in position. lVhen the Alocking ring'is sprung into locked position, acc1dental displacement thereof is practically impossible, as it is necessary to use' :1 suitable tool to jimmy the ring out' of said locked position. Therefore it is desirable, when the receptacle is used-for storing materials`to which access isdesired at frequent f lat right angles to the position shown in Fig. 2, to engage under the upper flange 15 of the the closure, for. instance by stamping out the sheet -19 at the proper points, to arrest the- .swinging movements of said latches 28 to# ward inoperative positions. y

In Fig. 3, the coverseating ring 13a 1s` constructed of sheet metal and is thus slightly dierent from that ofthe ring 13 Shown in Fi 1. *The outer ed e of the cover seat? ing ring 13a ,is connecte Iby a lap joint 11a with the side wall of the receptacle 10a. The .ring 13a is provided with ana-upwardly rojeeting bead 33 which cooperates with t e horizontal llange 16a. of the outer reinforcing ring l' to 'form a channel in wh1ch the,

ends of the4 latches 28 may be engaged .or

. in which the horizontal llange 26?x of 4the 29 by means of which the latches 28 are se# lookin ring may be inserted. The constructiono the cover shown in Fig. 3 is identical with that shown in Fig. 1. l While it is preferable to extend the'rivets cured. to the cover, only through Ithe upper v sheet 19, so that if the rivet should become which project thrll loosened leakage is prevented, it will be understood that in certain eases it may -.be desirable to extend the rivetsthrough both of the sheets 19 and 20 of the cover.

In Fig. 4, I have shown a construction in which the latches '28 are llocated on the interior face of the cover so that when the latch is swung to locking position, it will engage. under the lower Ilan e 14 ofthe cover seating ring in Fig. 1 or its equivalent in Fig. 3;" it will be l'lnderstood that in such case thelatches 28ffiare fixed upon stems 29 both sheets, 19 `and 20 of the closure and yond the upper sheet 19; the projecting ends are rovided with handles 30 accessible fromt e exterior of 'the closure for manipulating said latches.

In all lof the forms of my=invention, thev latches when in operative positions, securel' lock the closure or cover 1n lts closedposi- `tion, saidlatches being easily adjustable to. inoperative positions. in' which 'the' closure or coverisreleasedand -thus capable of being readily removed at will to expose theinterior of the receptacles. It will be understood that such latches when in their inoperative` positions do not interfere with the useof the locking ring.

It will be understood that various changes and modifications in the specific forms shown` and described may be made `within the scope 4of 4thel claims without departing from the spirit. of my invention.

I claim: L

1. In a receptacle closure, a cover -comprising an inner sheet andl an outer sheet secured together .adjacent to their marginal edges with the intermediateportions of said sheets in spaced relationship from each' other, a plurality of locking latches ,and

0* said latches to said outer means for securln sheet only, whereby leakage about -said se- Y curing means isprevented lby said inner sheet.

v2. The combination with a reeeptacleihav-Y 'ing an open end, and a pair of horizontally extending flanges lspaced one above the other at said open end, the lower of said flanges extending inwardly of the upper flange to form a support for a cover, of a cover having a horizon-tally extending pe-A ripheral flange adapted to be supported by said lower flange and thereto a lurality of latches 'for temporarily securmg it 1n closed position, said latches being freely movable upon their pivots into and out of locked engagement with the under side of said upper flange, -a split locking ring engageable with said upper I lange and said cover and movable into-'and out of locked engagement therewith. only bythe use 'of a leverage exertin tool, said pivoted latches when swung to fu l unlocked position providing suilicient clearance `space to permit the engagement of said split locking ring with said upper flange and cover, whereby'either said pivoted latches or said v split locking ring respectively may be inter to close said open- .end, said cover havingpivotally secured and upper flange for temporarilylocking v said cover in closed position for storage purposes or frmore permanently locking itin closed position for shipping purposes.

In testimony whereof I have hereunto set my hand. i v L' ALFoNs MAUSER. i
