WILLIAM G. AVERY, OF PAINESVILLE, OHIO.

FOUNDRY-BARREL.

Application filed April 8, 1918.

T 0 all whom it may concern.

Be it known that 1, WILLIAM G. AVERY, a citizen of the United States, and resident of Painesville, in the county of Lake and State of Ohio, have invented certain new and useful Improvements in Foundry-Barrels, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to.which it appertains to make and use the same. I The objects of the invention are to provide an improved form of metallic container or cask especially such as are employed in industrial plants for receiving materials or storing or shipping abroad or transporting the materials within the boundaries of the establishment. The containers are adapted to contain metallic articles such as bolts,

rivets, metal stampings or other articles either hot or cold, and hence they must be capable of enduring heat and rough handling without injury or distortion in shape.

It is particularly important that the united edges of the finished cask or barrel should be strongly reinforced, and the upper and lower margins should be strongly reinforced from integral material and all joints or overlapping parts should be strong and smoothly made, while at the same time the interior surface of the cask should be perfectly smooth so as not to injure the articles stored therein or interfere with the capacity of the cask.

The invention comprises a cylindrical cask having its circular margins heavily reinforced to several thicknesses, which appear as annular bands, around the edges, and also provided with overlapping longitudinal edges, which can be tightly secured together by means of spot welding or riveting to produce a practically indestructible container.

Further ob'ects of the invention are to provide a method of reinforcing the casks by turning backward upon themselves, the

- upper and lower marginal edges of the cask, and separating the lateral extremities of the reinforcing bands thus formed from the body of the cask so that they can be overlapped and riveted or spot welded together.

This manner of reinforcing the lower and upper edges of the cask and separating the extremitiesthereof so that they can be over Specification of Letters Patent.

lapped, makes it possible to bend back the vertical edges of the metal from which the cask is formed on opposite sides and to interlock the bent over portions, thus preventing the separation of the parts.

The peculiar methods by which these results are accomplished are hereinafter further described, illustrated in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a plan of the metal sheet from which the cask is made; Fig. 2 is a perspective of the meeting vertical edges of the cask showing the manner of reinforcing the upper and lower edges and the manner of interlocking the vertical edges thereof; Fig. 3 is a plan of the overlapping upper edges; Figs. 4, 5,

and 6 are similar figures illustrating amodified form.

A is the cylindrical body of the cask formed of a metal sheet, the vertical edges are bent backward upon opposite sides so that they can be interengaged with each other and the interhooked or interlocked edges when flattened down, will form a positive connecting means between the edges. These edges can be slidingly moved longitudinally of the axis of the cask, into engagement with each other and can be riveted or spot welded together. The circular edges of the body are reinforced to appear as if heavily hooped, by first bending the metal twice or more times outward upon the dotted lines C, C respectively, thus making the marginal hoop U as shown three-ply in thickness and able to endure a large amount of ill usage without being distorted in shape,

To make it possible to unite the extremities of the integral hoops or bands, the material is cut upon vertical and horizontal lines E and F as shown in Figs. 1 and 2 for one extremity and upon the lines G and H for the other or opposed extremities.

By making the cuts E, F, G and H in the second line of folding of the horizontal edges, the vertical edges B and B will be edges B and the projecting marginal extremity C and the extremity C overlaps the extremity C. I

The engaging parts are then riveted or spot welded together.

In Figs. 5, 6, and 7 the same general result is obtained but the edges are constructed in a slightly different manner. Here 0 and- P are the vertical edges respectively turned forward and backward.

Q is the marginal hoop or band formed of the metal edge twice folded back upon itself at R and S.

Upon one vertical edge 0 deep slots T are out upon the second folding line and upon the other edge P corners W are cut as deeply as the turned vertical edge on that side. When the opposed vertical edges are overlapped by sliding one over the other the projecting extremities Z, Z, of the bands or hoops overlap the opposed extremities as shown in Fig. 6 and the overlapping parts are spot welded thus making them tight and inseparable.

At Y, Y portions of'the ends of the vertical edge 0 are cut away to permit folding the edge 0 forward, whereas the vertical edge P extends the full height of the finished barrel.

Having described the invention, what I claim as new and desire to secure by Letters Patent isi 1. A sheet metal barrel comprising a cylindrical sheet of metal open at one side and having its vertical edges turned backwardly upon opposite sides and engaging with each other to form a vertical seam, said sheet of metal having its horizontal edges layers in contact with each other and having projecting extremities, one of the extremi ties being arranged in alinement with the horizontal folds, and the other extremity and the vertical seam being located at opposite sides of the horizontal folds.

2. A sheet metal barrel comprising a cylindrical sheet of metal open at one side and having its vertical edges turned backwardly upon opposite sides and engaging with each other to form a vertical seam, said sheet of metal having its horizontal edges outwardly folded to provide a plurality of layers in contact with each other and having projecting extremities, one of the extremities being arranged in alinement with the horizontal folds, and the other extremity being arranged at the outer side of the horizontal folds and the seam being arranged at the inner side of the horizontal folds.

3. A sheet metal. barrel having an open side with vertical edges one folded forwardly and the other backwardly and interlocked with each other to provide a vertical scam, the horizontal edges of the barrel being foldedoutwardly to form a plurality of plies and provide marginal reinforcing members, each reinforcing member having overlapped terminals, one of the overlapped terminals being located in 'the plane of the member and the other being laterally offset, the vertical seam and the laterally ofi'set terminal being located at opposite sides of the reinforcing member whereby the vertical and horizontal edges are adapted to be welded together.

In testimony whereof, I hereunto set my hand this 20" day of November 1917.

WILLIAM G. AVERY.
