Specification of Letters Patent.

Patented NOV. 26, 1918.

Application led March 19, 1918. 4Serial No. 223,326.

T0 all whom t may concern Be it known that I, JOHN D. KENNEDY, a citizen of the United States` residing at New Kensington, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Collapsible Barrels, of which the following is a specification.

This invention relates to a collapsible barrel and has for its primary object to provide an article of this character capable of withstanding excessive strains and further capable of being quickly disconnected and arranged in a folded position.

An object of the invention is to provide a cap of such a construction as to reinforce the body of the barrel against inward as well as outward distortion and to allow the cap to be readily connected to the body.

Besides the above my invention is distinguished in the novel form of locking means for connecting the cap to the body in a secure manner but allowing the same to be readily disconnected when force is applied in a predetermined direction.

With these and other objects in view the invention will be better understood from the following detailed description taken in confnection with the accompanying drawing wherein:

Figure l is a vertical sectional view of the barrel.

Fig. 2 is a detailed horizontal sectional view through the cap.

Fig. 3 is a detailed horizontal sectional view on the line 3 3 of Fig. 1.

Fig. 4 is a sectional view of an improved form of cap.

Fig. 5 is a sectional view of another form of cap.

Fig. 6 is a plan view of the securing element.

At the start I wish to call attention to the fact that although I have shown the body of the barrel provided with arcuate corrugations I wish it to be understood that the same may be square or of any other suitable shape in cross-section.

My invention consists of a body 1 composed in this particular instance of two sections 2 and 3. Each section at a central point is provided with a groove 4 providing a bead 5 that materially reinforces the central portion of the barrel. Seated in the groove 4 is a tie wire 6 for forcing the sections into engagement with each other and holding the same against displacement. The connection between the ends of the tie wire 6 may be accomplished in any suitable manner. As clearly shown in Fig. 3 it will be seen that the section 2 has its vertical edge portion 7 forced into the lianged edge S of the section 3.

As the caps 9 and 10 are identical in construction the following description will bev limited to cap 9. This cap 9 has its central portion 10a depressed so as to be arranged within the body of the barrel and to cooperate with the depending flange 11 to fornr a groove 12 the walls of which engage with, and inclose the corrugated end of the barrel body as clearly shown in Fig. 2. From this construction it will be seen that thesections 2 and 3 are materially reinforced against inward or outward movement due to the engagement between the corrugations and the walls of the groove 12 as clearly shown in Fig. 2. Thus it will be secn that this construction in combination with the bead 5 enables the sections 1 and 2 to withstand excessive inward or outward strain.

In the preferred form of my invention the locking device for the cap consists of a metallic strip 13 resting upon the central portion 10 and having its ends 14 passing through alining openings 15 in the cap and the body of the barrel. This strip is of resilient character so that the central p0rtion may be bowed when the ends are being inserted in the openings. When removing the strip it is necessary to arrange an instrument under the central portion of the strip 13 and bow the same upwardly so as to retract the ends from the openings. A very important feature of my invention is that the {iange 11 completely closes the protruding ends of the strip 13 so that the same will be protected from being mutilated or displaced.

That form of my invention illustrated in Fig. 4 is identical with` that I have just described with the exception that the cap 16 is centrally provided with a transverse rib 17 which besides reinforcing the central portion of the cap, constantly bows the strip 18 so as to insure a tight connection between the ends of the strip and the walls of the openings in the cap and body. In Fig. 5 I have shown the cap 19 and locking element 20 so arranged and constructed that the top portion of the side walls of the cap is not formed with an opening. In this particular instance an opening 21 is arranged in the flange 22 and the strip 23 is of sufficient length to allow the ends to project beyond the flange and flattened as indicated at 24. The protruding ends of the element 23 may be twisted by the use of an ordinary pair of pincers. v

From the foregoing description taken in connection with the accompanying drawing it will be apparent that I provide a barrel of substantial construction and which may be very readily folded for shipping purposes, and besides, the operation of the locking element 13 and the position thereof is such that the strain of the contents of the barrel against the cap willl act in a direction at right angles to the movement necessary to removing the ends of the locking element 13 from engagement with the body.

Having described my invention, what I claim is:

A shipping barrel comprisinga substantially cylindrical body provided with longi- Copies of this patent may be obtained for vecentseach, byaddressing the tudinally extending corrugations, said body being provided at each end with a pair of diametrically opposite slots, a head disposed upon each end of said body and formed as a circular member having its central portion depressed to .form an inner fiange bearing against the inner periphery of said cylindrical body, an annular flange formed at the outer edge of the head in spaced substantially parallel relation to said first named flange and engaged upon the outer periphery of said body, said inner flange being provided with a pair of diametrically opposite slots adapted to be brought into registration with the associated pair of said first named slots and a resilient strip disposable within the depressed portion of the' head upon the outer face thereof with the ends of said strip engaging through said registering'slots, the ends of said strips being insertible within said slots when said strip is in bowed` position.

In testimony whereof I aiiiX my signature.
