When the reenforced fibrous structure has thus been formed, the mandrel is collapsed sufficiently to enable it to be withdrawn through one end of the barrel structure. The construction and use of the mandrel is not described as it isa known piece of apparatus. When the mandrel has been withdrawn, heads 16 and 17 are secured to the ends of the barrel structures. These heads are formed of a metal having a lining 18 of impregnated paper or other suitable material. The outer peripheral edges of the heads are shaped to form annular recesses 19 into which the opposite ends of the barrel stave structure may be inserted. The head is then secured to the staves 13 by means of rivets 20 passing through the staves and the peripheral walls of the recesses 19 and drawing the walls of the recesses tightly against the fibrous structure enclosing the staves. Two rivets are preferably used for each stave symmetrically spaced near the side edges as shown in Fig. l. Bung

openings

21 and 22 may then be formed in the barrels and head respectively..

Hoops

23 and 24 may also be placed on theouter surface of the barrel, if desired, for greater strength.

The bilged metal stave structure may be formed in any suitable manner to provide the bilge form and the longitudinally extending openings 14. As illustrated, in Figs. 3 to 6 inclusive, blanks 25 of proportionate width and length are cut or stamped from sheet metal and then curved and bent or stamped to give them the required stave shape. That is, the blank is curved transversely as indicated at 26 in Fig. 6 and curved longitudinally as indicated at 27 inrFig. 5. When staves thus curved and assembled in a circular or cylindrical fashion with the side edges in abutment near their ends, the edges of adjacent staves diverge from point ofcontact toward the center of the stave as indicated diagrammatically in Fig. 4.

The Youter surface of the barrel may be protected and strengthened by means of sheet

metal surface plates

28 and 29 placed between the

hoops

23 and 24, and the outer edges of the heads 16 and 17 respectively. This covering sheet conforms in shape to that of the surface of the container and iits the latter. They serve to protect the outer surface of fibrous material from abrasion as well yas to strengthen the structure. Their use, however, is optional.

Through the above invention, a barrel or container is formed which has shaped staves having a rigidity, strength and toughness inherent in curved or rounded bilge sheet metal, and, therefore, capable of withstanding the shocks and stresses inherent in dropping the barrel or container on its chimes as is customary in handling barrels. The fibrous structure formed integrally through the openings 14 and covering both sides of the staves provides a surface to which coating materials such as paraii'in, wax or pitch, readily and permanently adhere, while at the same time it forms an integral non-separable structure with the staves 13. While `the container has the strength of a metallic structure, it has less heat conductivity and, therefore, chilled liquids may be exposed to warm temperature for a considerable time without undesirable changes in the temperature. l

Various modifications may be made by those skilled in the art without departing from the following claims.

What I claim is:-

1. A container having bilged metal staves in barrel formation, the side edges of said staves contacting at their ends and separating in the intermediate bilged portion and a iibrous structure covering the inner and outer faces of said staves and uniting to an integral structure through the ,spaces betwen the separated intermediate edges of said staves.

2. A container having metal staves in barrel formation, the side edges of said staves contacting at their ends and separating intermediate said ends, aA fibrous structure on the inner and outer'faces of said staves and uniting to an integral structure through the spaces between the separated intermediate edges of said staves, heads having peripheral recesses receiving the ends of said staves and means securing the stave ends in said recesses.

3. A container having metal staves in barrel formation, the side edges of said staves contacting at their ends andseparating intermediate said ends, a paper-wrapping on the inner and outer faces of said staves and uniting to an integral structure through the spaces between the separated intermediate edges of said staves, heads having peripheral recesses receiving the ends of said staves and means securing the stave ends in said recesses.

4. A container having metal staves in barrel formation, the side edges of said` staves contacting at their ends and separating intermediate said ends, a paper wrapping impregnated with an adhesive material on the inner and outer faces of said staves and uniting to an integral structure through the spaces between the .separated intermediate edges of said staves, heads having peripheral recesses receiving the ends of said staves and means securing the stave ends in said recesses.

5. A bilged container having a bilged sheet metal structure, the ends thereof being peripherally continuous and having widening spaces from near the ends to the central part of the container between stave areas, and fibrous wrappings on the inner and outer faces of said metal structure, said wrappings being cemented together through said spaces.

6. A container having bilged metal staves in barrel formation, the side edges of said staves contacting at their ends and separating in the intermediate bilged portion andpaper wrappings covering the inner and outer faces of said staves and uniting to an integral structure through the spaces between the separated intermediate edges of said staves. l

7. A container having metal staves in barrel formation, the side edges of said staves contacting at their ends and separating intermediate said ends, a fibrous structure on the inner and outer faces of said staves and uniting to an integral structure through the spaces between the separated intermediate edges of said staves, heads having peripheral recesses receiving the ends of said staves and means securing the stave ends in said recesses, hoops on the outer surface of said fibrous structure and protecting metal plates extending between said hoops and the heads of said container.
