2 Claims.

This invention relates to closures for open head metal containers of the nature of barrels or drums.

The principal objects are to provide for locking and sealing the removable heads of wide mouthed receptacles, such as barrels or drums,

and to provide means for accomplishing these results in a simple and expeditious manner and in such way that there is a saving in weight, which means a saving in freight as well as rst cost, and in such. way as not to sacrice strength, failure, if any, occurring in the head and not in the closure ring; and in such way as to provide a chime free from rough or sharp '-15 projections likely to cut or tear the hands of workmen.

The nature of the invention consists in the combination with the usual assembly of a shell or drum having an external roll at its top, and 2U a cover having a rim which seats upon said roll on an intervening gasket, of a chime for ultimately clamping said parts in sealed relation and consisting of a band of such section as under connnement and exerted pressure will 25- impose pronounced wedging action upon the parts to be sealed and whereof one of its ends is equipped with a tongue slot and tongue guide or deeetor and whereof the other end is equipped with a tongue and with a sealing lip or hold- '301 down for cooperation with the tongue, the closure ring or chime having provisions for auxiliary sealing and having provisions to facilitate the application and operation of a tool or tightening device.

In the accompanying drawing which illustrates the preferred construction and arrangement,

Figure `l is a sectional detail of the improved closure ring or vdrum in head locking and sealling position.

Fig. 2 is a top view of the preferred tool or clamping band for putting the closure ring or chime in locking and sealing position.

Fig. 3 is a detail of the tongue slot.

Fig. 4 is a detail of the tongue and its holddown.

Fig. 5 is a detail of the tongue and its slot before the tongue is bent to locking position.

Fig. 6 is a detail of the parts in locked posi- 50. tion.

Fig. 7 is a detail of means to facilitate the application of a tightening tool.

Figs. 8 and 9 are details of provisions for the application of a sealing strip or wire.

Referring to' 1, the numeral 5 represents @Rif the shell of an open head barrel or drum having an external roll 6 to seat a gasket '1 and the sealing rim 8 of a head 9. These parts are or may be as usual.

The improved closure ring is designated 10, and in practice it may be formed of a at strip of sheet metal, such as is used on packing boxes, the strip being pressed or rolled into channel or hoop form. Under preferred practice the legs of the channel are flared so that when the closure ring is under exerted pressure in order to draw its ends together, there will be a pronounced wedging action on the parts to be sealed.

One end of the channel has a part struck up from its web and between its legs to provide a tongue slot 11 and a'tongue guide or deiiector 12; and similarly the other end of the channel is formed wth a tongue 13 and at right angles thereto with a sealing lip or holddown 14.

When the ends are juxtaposed the tongue is deiiected by the guide or abutment 12 through the slot 11, is then bent :in a reversed direction and secured ush with the web by manipulation of the holddown or sealing lip 14.

It is a merit of the invention that further and 30 coincident lugs 15 may be struck up from the web in the region of the tongue and tongue slot and perforated for the passage of a sealing wire (not shown). After threading the wire through them, the lugs 15 are attened against the web 85 to obviate the hazard of rough or sharp projections.

Again, the web of the channel may have punched openings 16, the presence of which facilitates the application of pins (not shown) for 90' cooperationwith a tightening tool.

Under the preferred practice of drawing the ends of the closure ring together Iand of promoting the wedging action hereinbefore referred to, we use a clamping band 17, Fig. 2, having pilot lips 18 for justifying it with relation to the head of the drum. Its gap is bridged by a right and left threaded bolt 19 equipped with a tool 20 for cooperation with nuts 21 carried by 100 the respective ends of the clamping band.

Having described our invention, we claim:-

1. A closure ring or chime, comprising a metal strip of channel section whereof one end is formed with a tongue slot the back wall of which is formed `with a lip extension which functions as a tongue guide, and whereof the other end of the strip is formed with a tongue adapted to be passed through the slot and then bent backwards, the tongue end-of the strip having an V'integral bendable tongue adapted to overlie the tongue,

2, The\combination with acontainerV o f .open

port-ion at right langlestov the head construction having an extena1`ro11,' .a head having a sealing rim, and a sealinggasket between said roll and rim, of a vdivided chime vor closure ring of aring channel section for exerting wedging action on the head, gasket, and troll, said chime being formed at =one end with a tongue slot having an offset portion constitut- Laatzen;

end of the chime having fportion struck'up therefrom at rightangleslto ,the tongue and adapted to be bent into overlying engagement with the tongue.A A
