UNITED STATES ALBERT C. GRUNWALD, OF RIVER FOREST,

ILLINOIS, ASSIONOR TO PRECISION METAL WORKERS, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

REOEPTACL'E COVER.

Application. filed. June .9,

The present invention relates to receptacle covers and has as its primary object to provide improved means for fastening or locking covers on containers, and receptacles of various description.

It is a further object of .the invention to provide improved fastening or locking means for the cover which will always compel the seating of the cover in a predetermined angular relationship on the container.

Other objects will be apparent from the following description taken in connection with the accompanying drawing, illustrating a preferred-embodiment of my invention.

In the accompanying drawing:

Figure 1 is a vertical sectional view of the can or receptacle taken approximately on the plane of the line 11 of Figure 2;

Figure 2 is a plan view of the container, and

Figure 3 is a disassembled or exploded view showing the various parts making up the improved locking means.

The receptacle is indicated at 5, being representative of any type of container to which my improved cover is to be applied. As illustrative of such containers the cover may be applied to all cans, syrup dispensing receptacles and preserving cans, etc. In the oil can embodiment chosen for exemplification a handle 7 is secured to the side of the can body. The cover is indicated in its entirety at 9, this cover comprising a tapered spout 11 of any desired form.

The cover is formed with a downwardly turned peripheral flange 36 which engages over an annulus or ring 37 secured to the reduced neck 6 of the can. This annulus is formed with an inwardly extending flange 38 to provide an extensive seating area for the gasket 39 confined between the cover and this annulus 37. Formed around the lower edge of the flange 36 are a plurality of inclined keys or segments 41 that have looking co-operation with segments 42 on a looking ring 43. The locking segments 42 are turned inwardly and are also sloped to have cam co-operation with the sloped locking segments 41. These locking surfaces form in effect a bayonet joint for locking the cover on the can. The locking ring 43 has an inwardly turned flange 44 which sits on a ring 45 secured to the can body. A flange 46 on the lower edge of the annulus 37 over- 1924. Serial No. 718,712.

lies the flange 44, this flange46 and the ring 45 forming upper and lower seating surfaces for the rotatable locking rings 43. In assembly, the locking ring is first placed on the lower bearing'ring 45, after which the annulus 37 is slipped down over the reduced neck 6 and is Welded or otherwise suitably secured to this neck.

The locking ring 43 may be formed of sheet metal, and has diametrically opposite lugs 48 extending outwardly from the body of the ring, by which the ring can be turned with sufiicient pressure to force the cover 9 down firm against the packing ring 39. The

cover 9 may also be formed of sheet metal with its locking segments 41 rolled outwardly in the shaping operation. The members 41 are receivable in the openings 40 in assembling the cover on the can.

Where it is desired to compel seating of the cover in a predetermined angular position on the can or receptacle, a lug 51 is pro ected from the side of the annulus-37. A co-operating slot or recess 52 is cut through one of the locking segments 41, and through theflange 36, for engaging over this positioning lug 51. The presence of this lug 51 obstructs seating of the cover in any other position than in the predetermined angular position on the container.

In replacing the cover on the can, the locking segments 41 are passed through the openings 40 on the locking ring and the slot 52 is brought into registration with the lug 51, whereupon rotation of the locking ring 43 will force the cover down against the flange 38 with the cover in its desired angular position.

Having thus described my invention, what I claim is:

1. In combination, an oil can or the like, a cover for said can, inclined locking surfaces on said cover, a locking ring, inclined locking surfaces on said ring for engagement with the inclined surfaces on said cover and a lug for compelling seating of said cover in definite osition on said can.

2. In combination, an oil can or the like,

a cover for said can, locking segments having inclined locking surfaces extending from said cover, a locking ring having cooperating inclined locking surfaces for engagement therewith, and lug and slot means for centering said cover on said can. I

3. In combination, a container, a cover a ring member rotatively mounted on said flange and having inwardly projecting sloped cam members, a retaining ring fixed on said cylindrical lflange to prevent removal of said ring member, and a cover having outwardly extending sloped flange members to be received under said cam members to clamp said cover and can by rotation of said ring member.

5. In an oil can or the like, a container having a handle and an upturned cylindrical flange, a ring member rotatively mounted on said flange and having outwardly projecting sloped cam members, a retaining ring fixed on said cylindrical flange to pre vent removal of said ring member, a cover having outwardly extending sloped flange members to be received under said cam memhere, a curved spout on said cover, and stop means between said cover and can determining the rotative location of the dischargin end O'l': said spout.

In witness whereof, I hereunto subscribe my name this 4th day of June, l92a.
