SQUARE BARREL SHAPED CONTAINER AND ITS PRODUCTION

Japanese Patent JPS60217891

A

A rectangular barrel-like structure having four wooden stave sides and two wooden stave head sections, joined together by specially designed triangular corner members. Each of the staves used in making the side walls and in making the head sections are of white oak and are of tongue-and-groove construction. Additionally, each of the staves utilized in the wall sections contains a croze at the top and at the bottom for snug engagement with the staves forming the head sections. Each of the triangular corner members is truncated at the junction of the leg and the base of the triangle so as to form a planar section equal in width to the width of the wall section stave. The truncated planar section contains a projecting tongue on one side for engagement with a complementary groove of a wall stave of one side section and a complementary groove on the other for engagement with a projecting tongue of one of the wall staves of the other wall section. A series of bumper members comprising wooden pieces each equal in length to the width of a wall section and of two corner members are tapered at each end and are arranged transversely across the wall section near the top and near the bottom. A metal tensioning strap of conventional construction encircles the four wooden bumpers and tension is applied so that pressure is applied to the wall sections and particularly to the apex of the triangular corner piece. The forces, therefore, when resolved, are at right angles so that the side wall staves are drawn into tight compressive tongue-and-groove engagement. No glues or bonding agents are employed whatsoever.
