BARREL CLOSURE.

Application lcd January 29, 1924.

lily invention relates'to barrel closures, my more particular' purpose being to produce a barrel closure admitting of cheap construction, simple in operation and ellicient in action, and's 'table tor Vuse with oil and other liquids having great penetrative power'. y

More particularly stated l seek to produce a device ot this character, suitable tor use upon barrels` used in shipping oil over long distances, and in which the danger o1' leakage .is reduced to a minimum.

Reference is made to theaccompanying drawing forming a part et this specilication, and in which like reference characters indicate like 'parts ,throughout the several parts.

Figure 1 isa substantially central section through one :term of my improved barrel closure, various movable parts or' the device appearing in the positions they occupy betore the closure is sealed.

Figure 2 is a side elevation oi a steel barrel with my improved closure so applied thereto as to occupy a position substantially midway between the heads of the barrel.

Figure 3 is an end elevation ont a steel barrel, and shows my device as applied to the head thereof.

Figure 1 is a side view, partly an elevation and partly a section, showing another form of my improved closure.

Figure 5 is a fragmentary elevation of the uiecl'ianism shoivn in Figure 1, and shows the same as sealed.

A steel barrel appears at (Si, and carries a pair of annular supporting rims T, these parts being ot the usual or any desired construction.

The barrel is'provided with ai massive portion 8, serving as a base for the closure, and through this base extends'a bung hole 9.

The base S is provided with a Wall 10, integral with it and provided externally with threads 11. rllhese threads may be of any suitable size, but are preferably about sixteen to the inch. lhe base is further pro vided with another annular Wall 12, encircled by the Wall and concentric with the same. Vlfhis Wall 12 is also concentric with the bung hole 9.

jetween the Wall 10 and 12 is a channel 13 of annular form. Resting in the bottom oi this channel is a gasket 14 made ot cork or other resilient material and having the form of a flatring. Resting upon this Serial No, 639,222.

gasket a ring 15 made of sott-metal prei erably Amess alloy, or which may be a single pure metal, such as lead or aluminum.

A. revolvable cap is shown at 16, and has integral with it a peripheral iiange 1i' oi' annular form, this liauge being provided internally with threads 18, mating the threads 11 ot theiuall l0.

rEhe cap 16 carries an angular head 19, to be engaged by a Wrench and thus used for turning the cap. The capcarries a pair oi annular cutting edges 20 and 21, the edge l being encircled by the edge 20 and concentric thereto. Between these edges 20 and 21 is a channel 253, and mounted within this channel is a gasket 911 made ot cork or other resilient material.

W hen the cap 1G is turned relatively to the base 8 and in the proper direction, the cutting edges 2t) and 21 are pierced against the ring 15 and thus caused tocut into the same slightly, as indicated in Figure The cork rings l--l ind 241 are thus compressed, as indicateiL in Figure 5, and the cutting edges 20 and 21 are forced into the ring 15.

rlhus is .formed a very etl'ective seal, through which oil, however penetrating and limpid, is unable to pass.

It the closure mechanism is used more than once, each time the cap is screwed in position as above described the cutting' edges 2) and 21 out a little more deeply than before, and as a result the cork gaskets 14 and 211 are each compressed to a litt-le greater extent than before. Thus the seal as a Whole is progressive in its action, in that the movable parts occupy slightly diii'erent positions relatively to the stationary parts as the closure is sealed from time to time.

Br very important feature ot the device is the action the cutting edges 20 and 21, as they force Atheir Way to a greater or lesser extent into the ring They cut a little deeper each time they are used successively.

In the torni shown in Figure et the base appears at 8, and has nearly the s me construction as the one above desc in this instance, however, the annular channel 13 is occupied by a filling 25 by sol't metal, such as Amess alloy, aluminum or lead, The lilling should adhere to the base, so as to be, practically integral therewith, For this purpose the iilling may be cast or moulded in the channel. and a flux may be used tor the purpose of facilitating the in-
