Patented July 12, 1932 PATENT OFFICE mnrsannro, or momma, ALABAMA SHIPPING DRUM AND PROCESS OF MAKING THE SAME Application filed June 27,

This invention relates to shipping and storing receptacles, and more particularly to a metal drum for use as a shipping container for rosin and similar substances. It will be understood, however, that the container may be used for storing and shipping any material for which it may be found suitable.

At the present time it is customary to ship rosin in wooden barrels, but wooden barrels have been found unsatisfactory for a number of reasons.

The barrels contain between 400 and 500 poundsof rosin and it is therefore necessary to form the barrels of thick staves; This 5 adds to the weight of the container and increases freight charges, as well as making it more diflicult to handle the filled barrels.

Therefore one object ofthe present invention is to produce a container having the shape of a barrel, so that it may be easily rolled and guided during rolling, the container being formed of sheet metal so that it will be strong and durable, but at the same time light in weight.

Another object-ion to wooden barrels is the fact that the rosin is poured into them in a liquid state and, as the staves do not always fit close enough together, the barrels leak. This makes it necessary to-apply clay within the barrel in order to close the seams.

This takes time and, in addition, the purchasers object to paying for five or six pounds of clay at the price of rosin.

Therefore another object of the invention as is to provide a container formed of sheet metal and having elements formed the same united by joints which will be leak proof.

Another objection to the use of wooden barrels resides in the fact that they are not only heavy but are shipped to the producers knocked down and it requires skilled labor to put them together toform a tight leak proof barrel.

I construct the drum with a bilge which enables the workman to roll and handle the same with ease because he can roll the drum on the ground and steer it in any direction without any great effort.

Containers constructed in accordance with ,this invention overcome this objection, as

1930. Serial No. 464,307.

they are constructed in halves and nested one within another, the halves being united by the user to form complete containers. By th1s arrangement the nested halves occupy a small amount of space and a large number 5 can be transported in a railroad car or truck.

Another object of the invention is to provlde improved anvils of a very signple construction, whereby the producer can very easlly and quickly form joints to unite the on halves to form a complete container.

The invention is illustrated in the accompanying drawing, wherein- F lgure 1 is a sectional view showing the container forming sections supported by a a5 a circular anvil preparatory to forming a joint to unite the sections.

Figure 2 is a view of the container with the joint partially completed.

Figure 3 is a View showing the container applied to a horn-type anvil preparatory to completing the joint.

Figure 4 is a sectional view through the completed container.

This improved shipping container or receptacle consists of a drum resembling a barrel and is formed of end sections 1 and 2. Each section is of a tub-like formation and has annular walls 3 tapering from the open inner end of the section to its outer end so which is closed by a head 4. The head is ofthe sunken type, and has a marginal flange folded outwardly into engagement with walls of the section, as shown at 5, to form a tight joint and also form a rim, serving to shield the head and prevent it from being broken loose from the walls, if a filled container is roughly handled during shipment from one place to another. One section has its head formed with a center opening 6, bordered by an inwardly extending flange 7, so

that a closure may be fitted into place after the container is filled.

These sections taper towards their outer ends so that the-complete container will resemble a barrel in shape and, therefore, may be easily rolled and guided while being moved from one place to another. About its open inner end the section 2 is formed with an outstanding annular flange 8 bordered by I a circumferentially extendin lip 9, and the section 1 is formed with a ange 10 corresponding to the flange 8. Therefore the section 1 may be set upon the section 2 and the lip 9 folded downwardly to clinch the flange 10 between the lip 9 and flange 8, and form a bead 11, shown inFigures 2 and 3, and this bead then flattened against the walls of the section 1 to form a joint 12 is shown in Fi ure 4, which will be very strong and not lia le to leak.

When the sections are to-be assembled, the section 2 is set into a circular anvil 13, with its flange 8 resting upon the flat upper face of the thickened portion 14 of the anvil, and the section 1 then set in place with its flange 10 resting upon the flan e 8 and surrounded by the lip 9. The anvi is supported in an elevated position by legs 15, so that the section 1 will be held above the ground or floor of a building, and this also causes the container to be supported at such a height that the lip can be easily struck with a hammer and driven into clinching engagement with the flange 10, as shown in Figure 2, to form the bead 11.

After the bead 11 has been formed, the container is removed from the anvil 13 and ap-' plied to the horn or anvil 16. This horn is secured at one end to a bench or other support 17 and projects outwardly therefrom at an upward incline, as shown in Figure 3. When the container is applied to the horn, the horn extends inwardly through the opening 6 and the gage plate 18 moved along the horn until the head 19 of the horn is disosed beneath the head 11. The securing bolt or screw 20 of the gage is then tightened and the container can be turned with the head 19 always remaining beneath the bead. Therefore the head can be struck with a hammer as the container is turned and driven firmly against the walls of the section 1, to form a flat joint, as shown at 12 in Figure 4, and the two sections will be firmly held together.

It will thus be seen that a container will be formed which will be light in weight but, at the same time, very strong and not subject to leaks when the hot rosin is poured into the container through the opening 6. It should also be noted that the sections of the container can be very easily and quickly assembled, and that expensive machinery for this purpose is not necessary.

What I claim as new is:

1. A receptacle comprising opposed sections, each having closing means at one end and having opposed ends normally open and flanged, said flanged ends being constructed for subsequent interengagement to form a flattened tight joint disposed substantially parallel with the wall of the receptacle.

2. A shipping receptacle comprising a drum consisting of end sections each open at its inner end, the sections being tapered towards their outer ends and adapted to be nested one within another before assemblage, means being provided for uniting walls of the sections when open ends of the sections are disposed in abutting engagement with each other and form a complete drum with the joint formed at the junction of the two sections disposed parallel with the outer face of the receptacle.

3. A shipping receptacle comprising a drum consisting of end sections, each open at its inner end, the sections having their open ends dis osed in facing relation to each other, an means uniting walls of the sections at the abutting ends thereof and forming a complete drum the joint formed by the flanges of the walls being laid flat or parallel to the walls.

4. A shipping receptacle comprising a drum consisting of end sections, each open at its inner end, the sections having their open ends disposed in facing relation to each other, with their walls contacting and provided with outstanding abutting annular flanges, said flanges being bent to form a joint holding the sections in firm engagement with each other with the walls of said joint overlapped parallel with and in close contact with the wall of the receptacle.

5. A shipping receptacle comprising a drum consistin of end sections, each open at its inner end, t e sections having their open ends disposed in facing relation to each other, with their walls contacting and provided with outstanding abutting annular flanges, the flange of one section being formed with amarginal lip encirclin the flange of the second section, said lip eing folded into tight gripping engagement with the flange of the second section and both flanges then folded against the walls of the second section to form a tight joint uniting the sections with the flanges extended parallel with the walls of the receptacle.

6. A method of constructing a shipping drum consisting of forming end sections, each having an annular wall and a head at its outer end joined about its margins to the annular wall, placing the sections with their open ends in facing relation to each other, and uniting walls of the sections by a joint extending entirely about the drum and disposed parallel with walls of the drum.

7. A method of constructing a shipping drum consisting of forming end sections, each having an annular wall and a head at its outer end joined about its margins to the annular wall, forming outstanding flanges about the wall of the sections and bending the flange of one section to form an annular lip about the flange, placing the sections in alignment with their flanges contacting, bindin the lip into gripping engagement with tfle flange of the second section, and

then binding the flanges flat against the walls of the second section in parallel relation to each other and with the wall of the drum to form a tight joint firmly uniting the sections to form a complete drum.

8. A method of constructing a shipping drum consisting of forming end sections, each having an annular wall and a head at its outer end joined about its margins to the annular wall, forming outstanding flanges about the wall of the sections and bending the flange of one section to form an annular lip about the flange, setting the section having the lipped flange within an annular anvil with its flange resting upon the anvil, disposing the second section in an inverted position with its flange resting upon the flange of the first section, bending the lip into firm gripping engagement with the flange of the second section, setting the drum upon a horn passed inwardly through the head of one section and bending the flanges flat against the second section while turning the drum upon the horn.
