'1 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 foods, fluids, 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 for a. container of this type an improved closing,

sealing and locking means comprising a resilient split ring and a locking means for the ring the construction of which is simplified to facilitate the positioning of the ring and locking its ends together and to reduce the cost of manufacture of the ring and locking means. a

Another object. of the invention is to provide for a container of this type an improved split ring carrying on one end thereof a locking means, the ring being constructed and arranged to be positioned and removed independently of the locking means and the latter being arranged, to engage the other ring end and lock the ring ends together, whereby the lockingmeans may be made of small elements of simplified construction; readily connected and disconnected to the other ring en to operate.

A' further object of the invention is to provide for a container of this type an improvedcover closing, sealing and locking means which does not interfere with the handling, stacking, storing and rolling of the containers.

A still further object of the invention is to provide an improved ring construction having a locking means so related to the ring and outer walls of the container that the positioning and removal ofthe ring may be easily'efiected.

Other objects of the invention will be appar ent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings:

Fig. 25 is a view substantially similar to Fig. 24, but showing the locking means in operated position.

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 side wall I is provided with the usual rolling hoops la (only onebeing shown). The upper end of the side wall is rolled over outwardly to 50 form a continuous circumferential bead 1 and the cover 2 has a circumferential wall or flange 4 arranged to engage a packing or'gask'et 5, seated on the bead I and effect a closing and of the container. The cover is preferably cupshaped so as to flt or telescope within the open end of the side wall I, the flange 4 projecting outwardly to lie over the packing 5.

8' 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 60., 6b, engage the flange 4 and lower side of the bead 3 to effect sealing of the cover in position. The ring 6 is preferably formed of resilient metal and as its ends are unattached, it may be readily expanded circumferentially and its ends separated laterally sufliciently to be positioned around the bead and flange and then contracted circumferentially into engagement therewith, as shown in Figs. 1, 2 and 5, in which position the cover flange 4 is secured to the bead 3. The operation of contracting the ring is preferably accomplished by imparting thereto several taps or blows at varying points around its circumference. Such contraction serves to force the flange 4 throughout its circumference toward the bead 3 substantially axially of the container, thereby uniformly compressing the packing {and eifecting a liquidtight seal for the container.

1 indicates as an entirety a locking means carried entirely on and below the lower wall 62) of the ring adjacent one end thereof so as to permit the free expansion and contraction of the ring when being positioned, as well as its free expansion when being removed. The locking means are adapted to be detachably connected to the other end of the ring (see Fig. 2) to lock them together, after the ring is positioned, as above set forth. When the locking means are operated into their locked position, the compressibility of the packing 5 allows the ring to contract slightly circumferentially, as shown in Figs. 3, 4, 6 and 'I; as a result of this contraction the upper and lower walls 60, 6b,, serve to tightly seal the cover in position, in which position the cover is held by the locking means.

Referring to Figs. 1 to 11, inclusive, I provide on one ring end a depending wall 8 having at 4 its lower end an outwardly extending lug 8a: to

' opposite sides of the lug.

50 I between its ends, the pivot ill being arranged near the inner end of the lever to provide out- 3 wardly of the pivot a relatively long portion 55 disposed pin ll, adapted to detachably engage which serves as an operating handle. The inner end of the lever I0 is provided'with a vertically the other ring end. The other ring end is pr0- vided with .a depending wall I! having an outwardly extending lug l3- in which is: formed a series of notches, into any one of which the pin ii may be inserted (see Fig. 2), following which the lever l0 may be operated from the Fig. 2 position inwardly, horizontally toward the side wall I- to the position shown in Figs. 3, 4, 6 and 7. As shown, I provide a series of notches which permit the pin II to have an adjustable, detachable connection with the other ring end to eflect the desired tightness or to compensate for different thicknesses in the packing or variations in the size of the bead. Also, by providing a series of notches, the ring may be tightened or contracted from time to time to compensate for wear or setting of the gasket to maintain and insure an absolute seal. When the lever in is operated to the position shown in Figs. 3, 4, 6 and 7, an imaginary line extending through the axes of the pivot 8 and fulcrum Hlf lies inwardly of the axis of the pin ii; accordingly, the lever is locked in its operated position. The lever I0 is preferably made of two correspondingly shaped parts the inner portions of which are spaced to support both ends of the pin II; the outer portions being preferably spot welded together. In this arrangement the spaced portions straddle the lug i3 and the pin I l engages the walls of one notch between them, whereas the outer end portions of the links 9 are bent laterally so as to lie on the outer sides of the lever parts and engage the opposite ends of the fulcrum it. In this arrangement, the locking action is transmitted in the plane of the lugs 8x and i3 and substantially in a direction parallel to the plane of the ring, so that inthe contracting operation of the latter, due to operation of the lever l0,

. no twisting forces are imparted to the ring ends and the upper and lower walls of the ring move substantially at right angles to the axis of the container.

In the illustrations above referred to the notches [4 have side walls i4a inclined away from the adjacent ring end; accordingly, when the lever is swung outwardly away from the side wall I, the pin ll automatically disengages the adjacent notch l4 (see Figs. land following which one ring end may be initially sprung outwardly (see dotted lines in Fig. l) and progressively disengaged from bead 2 and flange 4. By providing notches having side walls 14a which extend substantially radially of the ring axis, as shown in Fig. 12, the notch serves to retain the pin ll therein when the lever in is moved in either direction, so that in the opening movement of the lever, indicated by the arrow :1: (Fig. 12), the lever acts to initially spread or expand the ring wherebyits removal is facilitated. When the lever in is moved to its operated position, its outer end portion is related to a lug l5 provided on a wall i6 also depending from the lower wall 6b of the ring, so that by means of a wire threaded through suitable openings formed in the lug and lever and a lead slug H, the lever is sealed against unauthorized operation. The walls 8 and i2 are preferably disposed in line with the terminating edge of the wall 6b, being welded to the latter and the lugs 81: and I3- and the locking elements are of a size and shape to lie entirely within an imaginary circle equal in diameter to that of the side wall of the ring, as shown in Figs. 3 and 6.

Figs. 13 and 13a show a construction in which the elements of the locking means are similarin construction to like elements already described, but the mounting of such" means on one ring end and their attachment and detachment with the other ring end are reversed, as compared to the arrangement shown in Figs. 1 to 11; that is, the lever Ilia: is pivotally mounted on one ring-end and the outer end of the links 9:: is unattached to the other ring end when the ring is being positioned, but is adapted to be adjustably and detachably connected thereto after the ring is positioned (see Fig. 13). In these views the inner end of the lever is pivotally mounted on a lug ill to swing about a, vertically disposed pivot [Bx-and the outer free end of the links 9:: are provided with a vertically disposed pin l9 adapted to engage the walls of any one of -the notches 20 formed in the hori-.

zontal lugZl. The lug 2| is supported and constructed similar to the lug l3; and when the pin i9 is so engaged and the lever Illa: is moved in-- notches substantially radial to the ring axis, as

shown at 20a. in Fig. 14, these side walls serve to retain the pivot or pin i 9 in the adjacent notch when the handle Illa: is moved in either direction, so that outward movement of the handle or lever efiects an initial expanding move- 5 ment to the ring. The lever and links are slightly curved to conform to the shape of the wall I.

Fig. shows a different embodiment of the invention in which the locking elements are similar to like elements shown in Figs. 1 to 11, in-

elusive, but are mounted on one ring end and detachably and adjustably connected to the other ring end to operate on horizontal axes. 'In this arrangement, the outer ends of the'links 911 are pivoted by means of a horizontally disposed pin or pivot 22 to the opposite sides of a vertical wall 22' depending from the ring wall 6b adjacent one end of the ring and the pivot pin 23 on the inner end of the lever I011 detachably engages the wall of one of the notches 24 formed in the lower free edge of a vertical wall 25 depending from the wall 6b adjacent the other end of the ring. The operation of applying the ring and thereafter operating the locking elements to the position shown in dotted lines in Fig. 15 are similar to like operations described in connection with the embodiment shown in Figs. 1 to 11, inclusive. The lever I01 is formed of hingedly connected sections preferably having abutting walls (see walls Him in Fig. 18) to limit the articulating movement of the sections, such hinging permitting the outer end of the lever to swing free of the container wall I when being operated. The side walls of the notches 24 may be inclined away from the adjacent end of the rin as shown in Fig. 15 or disposed vertically as shown at 24a in Fig. 16, whereby opening movement of the lever lily will impart an initial expansion to the ring 6.

Figs. 17 to 22, inclusive, show a construction 59 similar to that shown in Fig. 15 and wherein the elements of the locking means are similar in construction to like parts already described and operate about horizontal axes,,except that the inner end of the lever is pivotally mounted on the lower wall 6b adjacent one ring end and the outer or free ends. of the links 92 are adapted, after the ring is positioned, to be detachably and adjustably connected to the other ring end. In these views, 25 indicates a vertical wall depending from the ring wall 611 adjacent the opposite end of the ring, the lower edge of this vertical wallbeing formed with notches 28 into any one of which the horizontally disposed pin 29 carried by the free ends of the links 92 may be inserted (see Fig. 17)

5 when the locking means are to be operated to their closed or locked position, as shown in Figs. 21 and 22. x

The lever lliz is preferably of sectional construction so that its outer portion may clear 7 the wall I, the pivotal connection between the lever sections being arranged to limit their articulation as shown at like in Fig. 18. As shown in Figs. 17 and 21, the side walls of the notches 28 areinclined away from the adjacent ring end to permit the ready and automatic disconnection of the links from the adjacent notch when the' lever is moved to its open position, but byextending these side walls vertically as shown at 28a in Fig.23, such movement of the lever will impart an initial expansion to the ring.

Figs. 24 and 25 illustrate a different embodiment in which the lever I0 is permanently pivoted to the wall I3 and the outer ends of the links 8 are permanently pivoted to the wall 8:: and the inner ends of the links are adapted to be detachably connected to the lever l0 intermediate its ends. To provide for the attachment and detachm'ent of the lever and links, the lever I0 is provided with a pin III" the ends of which extend laterally from its opposite sides and the links, which straddle the lever, are formed with a series of alined notches 9"into which the pin may be inserted (Fig. 24) when these locking elements are to be operated to the lockingposition, as shownin Fig. 25. The links are preferably connected together by a plate 9'. By swinging the lever and links to an abnormal position, they may be readily detached to permit free manipulation of the ring.

In the forms of construction shown in Figs. 15

to 25, inclusive, the elements of the locking means are slightly curved laterally to conform to the shape of the container wall I and when in operated position, a line extending between the pivots for the-inner end of the lever and outer ends of the links lies inwardly of the pivotal connection between the links and lever, so that the latter is locked in its operated position.

It will be noted that in the several forms of construction shown in Figs. 12 to 25, inclusive, as set forth in the first disclosed embodiment, the elements of the locking means, when in locked position, lie below the ring 5 and'entirely within an imaginary circle equal in diameter to the side wall of the ring, so that handling, storing, stacking and rolling of the containers are not impaired. It will also be noted that as the locking associated with the container. This arrangement prevents the ring from becoming misplaced or lost.
