M; MAMBOLJRG SHEET METAL FILE UNIT Filgsd Nov. 17, 192'?" MATHIAS MAMBOURG, OF LUXEMBUBG, LUXEMBUEG SHEET-METAL FILE UNIT Application filed November 17, 1927, Serial No. 233,992,.anrl in Germany November 533, 1926.
The present invention relates to metal piling, and more particularly to piling which is built up of multiplicity of interlocking sheet metal sections or unit its object being the provision or an improved unit of the character indicated so constructed as to avoid various detects inheren inthe units hereto fore employed while, at the same time, possessing certain advantageous features of its own.
It has been attempted in the past to roll metal sheets to form the pile sections or units. without regard to the distributional the metal, which naturally resulted in waste and lack of economy in material because the finished articles were not always satisfactory as to resistance, water-tightness, etc; consideration being paid for the most partv solely to the requirements of the rolling opera- 1 tion. Experiments were made inconstructing both low and high forms of sections in various ways to improve the resistance as well as the facility of rolling, while avoiding secondary strains in the metal and too rapid coolin thereof: but such experiments like- C I ,a
. constantly-tight joints.
The single figure of the accompanying drawing is a horizontal cross-sectional view or one of the improved pile units of the invention, with portions of the two immediately-adjacent units interlocked therewith.
As shown in said drawing, the pile section or unit consists of an intermediate portion or web and two end portions or wings. The
web, indicated at a, occupies a slanting position in the unit, and the two wings are integral with it, each wing embodying two branches or membersb and 0 arranged at right-angles to each other. The inner branches 6 of the two wings are disposed perpendicularly to the neutral axis of a seies of pile sections or units taken in horizontal section, while the outer branches 0 are parallel with said axis. The web a is thinner than the inner wing branches Z2, and the latter, in turn, are slightlythinner than the outer branches 0, and the slant of the said web I is such that it is disposed at an obtuse angle both to the branches Z) aswell as to the direction in whlch the branches 0 extend, as 1s clearly shown.
The successive units or sections are designed to be connected in interlock by means of joints which are somewhat analogous to ball-and-socket joints; and in the construction illustrated (which is not essentially limitative) the two members 0! and e corresponding, respectively, to the socket and ball 1 members of such joints are provided one on one endand the other on the other end of each unit. Both members are of special construction, and both are essentially resilient or elastic to some degree. The socket member (Z has the form of a crescent, and the companion or complemental member 6 is also crescent-shaped but is of smaller size or diameter, such shaping producing the desired resilience; but the two members are of opposite concavity so that the horns, so to speak, of the socket will extend over and oppositely to those of the inner head or member. 7
Due to this shaping and interfit of the two members, they will constantly maintain the desired tightness, while their initial position- 7 ing and jointing 'can be readily and quickly efiiected. The rigidity of the unit is in creased by providing the right-angular wings V at the ends of theweb, and the resistance is extremely high in proportion to the amount of metal used. Finally, the rolling operation can be carried out regularly and at high speed, thus avoiding waste and reducing production costs.
I claim as my invention:
A sheet metal pile unit, comprising an in termediate web portion "IVlllCll occupies a slanting position 111 the unit; and two wings integral with the web and located at the ends thereof and each shaped to form a ri ht dihedral angle; said web being incline at an obtuse angle to the inner branches of the wings and to the direction in which the outer branches of said wings extend.
In testimony whereof heaflixes his signature. s
