CONTAINER Filed July 11, I954 5 HO/V19.

Patented Sept. 3, 1935 UNITED STATES PATENT OFFICE '7 Claims.

This invention relates to containers, including barrels, and particularly to those made from thin sheet material, like ply wood, fiber sheets, etc.

When making a container body of sheet mate- 5 rial, one or more longitudinal joints are necessary,

where parts of the sheet come together. These joints are sometimes made as butt joints, having a thin piece or strip of some kind, as sheet metal, lapped over the abutting parts, and are securely fastened thereto by clinched rivets or staples. Some longitudinal joints are formed by lapping the adjoining parts and securely fastening these lapped parts together by clinched rivets or staples, thus eliminating the necessity of using an extra overlapping strip, as with a full length, butt joint. But the ends of such a longitudinal, lapped joint form in the case of a barrel, long, triangular openings, at the barrel heads, permitting a granulated or powdered barrel content to sift through.

One of the objects of my invention is to provide a construction of barrel or container made of sheet material, wherein the longitudinal joint in the body of the. barrel or container is mainly of lap formation, terminating at its ends in transformed butt formations at the peripheral zones of the barrel headers, so as to there present a continuous thickness of material next to the periphery of each barrel or container head, and thus avoid any triangular opening at the joint portion adjacent the barrel heads, which would otherwise be formed without resorting to such transformation into a butt portion of joints.

Another object in connection with the transformation of a portion of the lap joint to a butt joint, at the heads, is to strengthen the head ends of the barrel by having a continuity of contact made possible at the butt portions of the joints, between the outside hoop and the two liners, on the opposite sides of each header, which are firmly attached, with the body sheet, to the outside hoop.

A further object of my invention is to provide a sift-proof seal at the change of formation of lap joint to butt joint, by cementing over the cracks, paper or other thin material, suitable for the purpose, or by the formation of a cement film across the cracks.

Another object is to provide with each header disc, an overlapping, sealing sheet, within the barrel and next to each disc, to make the joint sift-proof around the periphery of the disc.

A further'object is to strengthen the thin sheet body of a barrel, at one or more zones, between theheaders, by means of a stifiening hoop put next to the inside of the barrel body, to serve as an arch support to the curved thin wall of the barrel, to strengthen the same against an outside impact.

And a further object is to stiffen and strength- 5 en the inside hoop by providing an outside hoop, opposite the inside hoop, fastening together the two hoops, with the barrel body between, by some clinched fastening means, as rivets, nails or staples, forced therethrough.

With these and other objects, which will hereinafter appear, my invention resides in certain construction, one embodiment of which is illustrated in the drawing, and. is hereinafter described. Its features are explained, and what I claim is set forth.

In the drawing,

Figure 1 is a perspective view of a barrel or container embodying my invention. Parts are broken away to illustrate the construction.

Figure 2 is an inside view of a joint fragment of the barrel shown in Figure 1.

Figure 3 is an inside view of the same joint structure shown in Figure 2, but exclusive of the header and liners, showing how the lap joint merges into a butt joint, by having a notch in the corner of the inside lap portion, of the longitudinal joint.

Figure 4 shows a similar joint structure to that shown in Figure 3, but has the notch in the corner of the outside lap portion, of the longitudinal joint.

Figure 5 shows the same joint structure illustrated in Figure 4, except it is here shown reversed in position to correspond to the lower part 5 of the longitudinal joint, shown in Figure 1.

Figure 6 is a fragmental mid-section of a barrel, showing the wall distorted and separated from the outer hoop, by an impacting object, in the absence of an arch formed by an inner hoop.

Figure '7 illustrates a section of barrel wall with an inside hoop serving as a supporting arch.

In the figures, the bent sheet [0, forming the barrel or container body may be of any material, including ply-wood, which may be of any number of plies, and is shown in the drawing to be of three-ply wood, having a longitudinal joint I l with a long portion [2, which is shown to have an outer part I3, overlapping an inner part M. The parts [3 and I4, being integral with the body sheet H), are held overlapped together, by clinch fasteners l5, which may be rivets, staples or nails. The upper corner, of the joint part I4, is notched at l6, and the corner 11, of the outer part I3, is bent into the notch l6, so that it presses tight 5&

against the horizontal edge l8, of the notch 16, and so that the long edge 59, of the part [3, butts against the vertical edge Zil, of the notch 16. The butt joint 2!, so formed, is in the zone of the plane, of the header 22, seated upon an inner liner 23, and has a paper disc seal 25-, overlapping the header 22, sufiiciently to lay next to the periphery of the header 22, and to extend up behind the outer liner 25. The horizontal edge I 8, of the notch It, is preferably positioned to come next to, and to be below the inner liner 23. In the same zone with the liners 23 and 25, and the header 22, is an outside hoop 26, wide enough to be properly engaged by clinched fastening means 2?, binding together. the hoop 26, the outer liner 25, the upstanding part of the paper seal 24 and the body sheet NJ, and also the inner liner 23, with the body sheet It and the hoop 26.

The lower end of the longitudinal joint H is shown to have a transformation from a lapped joint portion to a butt joint portion, wherein the notch 28 is made in the lower corner, of the outside joint part I3, and the lower corner of the inside joint part I4 is bent outward, so that it bears against the horizontal edge 29, of the notch 28, and so that the long edge 30, of the inner part 14, butts against the vertical edge 3 l of the notch 28. The butt joint 32, so formed, is in the zone of the plane of the lower header 33, associated with liners 23 and 25, outside hoop 26, and paper seal 24, the same as with header 22 at the top of the barrel. It will be noticed in Figure 1, that the horizontal edge 29, of the notch 28, is on top of the lower, of the hoops 26.

Referring now to the stiffening and strengthening means fixed to the barrel body it, midway of its length, there are shown two hoops, one marked '34, on the inside, and one marked 35, on the outside, with clinched fasteners 36, binding the hoops and the body wall It together. A suitable paper patch, or film of glue or cement covers the cracks about the butt joint transformations and the joints.

In Figurefi is shown a wall section fragment marked Ill with an outer hoop fragment marked 35*, with two spaced clinched rivets marked 36 in between which, but to one side of the hoop 35 is an impacting object, marked 37, shown to have forced the wall section Ill inward, from the hoop 35%, between the rivets 36 in the absence of an inner hoop, to prevent this distortion.

In Figure 7- is shown a wall section fragment marked Ill with an inner hoop fragment marked 34*, and two spaced clinched rivets se in between which, but to one side of the hoop 36 is an impacting object, marked 31 shown to have been resisted and held'against distorting the wall section Ill by the arched action of the inner hoop 34 Where an outside and an inside hoop are used in the same zone, as 35 and 36 respectively, shown in Figure l, with clinched fasteningmeans 36, therethrough, the hoop 35, while in itself will resist anoutside impact, also will strengthen the inner arching hoop 34, against an inward distortion of the barrel wall body lli.

While I have shown and described a barrel or container body made of a single sheet of material, obviously the body can be made up circumferentially of a plurality of sheets, having a plu- .or both ends,.or at any intermediate point in the zone of an interior or exterior hoop. The transformed butt formation affords a joint portion of continuously uniform thickness, with the other parts of the sheet barrel wall contacted by hoops, liners or headers. Any crack co-incident with the formation of such a butt portion, of joint can be easily sealed over by cementing over the-crack a piece of suitable paper, or by covering the crack with a film of cement or glue, as above indicated.

The paper sealing disc 2 1, used to seal the joint at the periphery of the header 22, is enough larger in diameter than the header 22, to be brought up behind the upper liner 25, which, when secured in place by clinched fasteners, binds the peripheral overlap of the paper disc 25 to the barrel body 63.

Relative to the inside hoop 35, its resistance, serving as an arch,-to stiffen and strengthen the body wall it, against distortion by an impacting object 3?, is illustrated in Figure 7, while in Figure 6, the impacting object 37, is represented as 7 having partly pushed in the wall section it, at a portion which is between the fasteners 36%, and away from the outside hoop section 35 Inasmuch as changes in the one embodiment of my invention herein illustrated and described. can be made without departing from the spirit and scope thereof, I wish to include all forms and changes which come within the purview of. the

following claims.
