Claims.

This invention relates to a container of the type in which one end is open and the head for such end constitutes a removable cover adapted to be sealed to form a liquid tight container for 5 foods, uids, semi-fluids, greases and other materials. By preference all portions of the container are formed of sheet steel.

One object of the invention is to provide forv a container of this type an improved cover closing and sealing means comprising a split 'ring having on and below its lower wall devices of simple and economical construction for contracting the ring and circumferentially applying through the ring walls uniform pressure to the container cover to effect a sealing thereof.

Another object of the invention is to provide for a container of this type an improved cover sealing means comprising a split ring having below the ring and connected to its ends devices for contracting and expanding the ring, these devices being so mounted that very little space is required for operating them.

Another object of the invention is to provide for a container of this type a cover closing means comprising an exteriorly mounted split ring and an operating means therefor disposed below and concentric to the ring, one operating element being of sectional construction to permit operation of said means in a plane substantially concentric to the axis of the ring.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description, taken in connection with the accompanying drawing,

` wherein Fig.- 1 is a plan view of a container showing thereon a cover closing and sealing means embodying my invention.

Fig. 2 is a fragmentary side elevation, enlarged showing the position of the ring and operating means when the ring is ready to be clamped or contracted into inal position.

Figs. 3 and 4 are sections on the lines 3 3 and 4 4, respectively, of Fig. 2.

Fig. 5 is a view similar to Fig. 2, but showing the contracting devices in operated position and the ring in nal position.

Fig. 6 is a fragmentary section on the line 6 6 cf Fig. 5.

The container illustrated is of the steel drum or barrel type, having a side wall I, a cover 2 and a bottom wall or head (not shown). The upper end of the side wall is rolled over outwardly to form a continuous circumferential bead 3 and the 55 cover 2 has a circumferential wall or 'iiange 4 arranged to engage a packing or gasket 5 seated on the bead 3 and eilect a closing and sealing of the container. The cover is preferably cup'- shaped so as to nt or telescope within the open end of the side wall I, the flange 4 projecting out- 5 wardly to lie over the packing 5.

6 indicates a split ring substantially U-shape in cross section and when positioned, the ring surrounds the bead 3 and its upper and lower circumferential terminating walls 3a, 6b, engage the l flange 4 and lower side of the bead 3. 'Ihe ring 6 is preferably formed of resilient material to per` mit it to be expanded substantially circumferen-v tially suillciently to be positioned around the bead 3 and then contracted to effect compressing of 15 the gasket 5 and sealing of the cover flange 4 to the bead 3.

, 1 indicates as an entirety an operating means comprising a lever 3 and a link 9, the latter being pivotally connected at I0 Ion a horizontal axis'gg to the lever near its inner end. so that the outer end portion of the lever may serve as van operating handle. The inner end of the lever 3 and outer end of the link 3 are pivotally connected on horizontal pivots II, I2, respectively, to walls I3, I4, respectively, depending vertically from the lower ring wall 6b. 'Ihe lever 3 and link 9 are so proportioned andconnected one to the other that when the lever is' operated toward the right as viewed in Fig. 2, the ring is expanded and may be positioned over and around the bead 3 and flange 4; thereafter, movement of the lever to the left to the position shown in Fig` 5 will contract the ring circumferentially, the effect of which is to force the cover flange 4 in the direction of the bead 3, thereby compressing the gasket 3 and sealing the cover. When the lever 3 is moved to the Fig. 5 position, the ring is locked in position'. In this position, a line extending between the pivots II, i2, lies inwardly o f the pivot- I0 to normally maintain the lever in its operated position. The inner portion of the lever 8 terminates in two spaced strips la suitably secured l (as by welding) at their outer ends to the opposite sides of a tongue 3b. The'inner ends of the strips 3a straddle the wall I3 to which they are pivoted, as above set forth. I prefer to provide two links 9 which. at their outer ends, straddle the wall I4 to .which they are pivoted as already described. I'he inner end portions of the links 3 50 are bent laterally to be disposed on the outer sides of the strips la and support the opposite ends of the pivot pin I0, which extends through alined openings formed in the inner end portions of the strips. In this arrangement the applied force in contracting or expanding the ring is in line with the walls I3, Il, so that twisting of the ring ends is avoided. The pivots for connecting the lever to the wall I3 and links to the wall I4 and for connecting the links to the lever are preferably riveted over at their ends so that these parts are permanently but loosely connected.

The lever 8 is provided with a hingedly connected outer section 8', which permits it to clear .the container wall I when operated in either direction.

The adjacent walls of the hinged lever sections are so related, as shown at 8m, that the swinging movement of the outer lever section is limited. 'I'he lever I0 and links 9 are curved laterally to conform to the shape of the container wall As will be understood from Figs. 1, 4 and 6,.

the operating means, when in operated position, are entirely below and parallel to the ring wall 6b and lie within an imaginary circle the diameter of which is equal to the diameter of the outer wall of the ring; accordingly, the operating means do not prevent the container from being stored and rolled in the usual manner.

By locating the ring `operating means below the ring and around the side wall of the container, the means are protected from the elements and the cover is left free for painting, lithographing or embossing.

The ring wall 6b is provided with a depending member I5 having at its lower end a lug I6 formed with an opening which substantially registers with an opening I'I formed in the lever I0 near its outer end, so that a wire may be threaded through the openings and its ends connected by a slug I8 to prevent unauthorized operation of the operating devices. The hinge section of the lever permits it to be positioned over the lug I6 as shown in Figs. 1, 5, and 6.

To those skilled in the art to which my invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from th spirit and scope of the invention. My disclosures and the description herein are purely illustrative and not intended to be in any sense limiting. r
