To all whom it may concern:

Beit known that I, FRIEDRICH WILIIELM LANG, engineer, a subject of the German Emperor, residing at Meridianstrasse, Hamburg, Germany, have invented certain new and useful Improvements in or Relating to Metallic Piling; and 'I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled -in the art to which it appertains to make and use the same.

This invention relates to walls formed of steel or other metallic sheet-piling acting as a supporting-plate, with rigid guides or connections.

In the accompanying drawings, Figure 1 shows a horizontal section through a wall construct ad according to my said invention. Figs. 2 to 6 are cross-sections, on a lar er scale, through several forms of connection etween the individual plates of a wall.

The metal plates t, which according to the purpose for which they are intended are curved to .1 greater or less extent and are bent at their longitudinal edges into the shape of a hook, are so driven into the ground that their overturned edges or uides a b c d 2, Figs. 2 to 6, engage one aother and cannot shift longitudinally. The possibility of these joints opening out or becoming leakyas occurs, for instance, in the wood, corrugated-iron, or other walls as ordinarily constructedis here completely recluded. By the engagement of the hookike edges with one another what-may be termed a labyrinth joint is formed. which affords in the case of walls and the like a reliable and tight joint, even against the finest and most drifting sand.

Horizontal stresses H due to the strain on the face of the supporting-plates are completely taken up by the mutual engagement of the longitudinal edges or guides, and thus the desired favorable action of the curved members as supporting-"plates is insured.

The wall may be strengthened in various ways. In building pits for piping this is preferably eflected, as shown in Fig. 1 of the drawings, by arranging a strengthened longitudinal beam Z in front of the guides and driving in small wooden Wedges it between the beam and the overturned edges of the plates t, or in place of wedges uprights may be employed which transmit the vertical bearing pressure from the plates to the beam and struts.

In case of single walls standing free the wall can be, for instance, supported by additional pile-props 'm, rammed in at the back of or by tie-rods n, arranged in front of the plates, as shown in the lower part of Fig. 1.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A wall comprising a series of interlocking sheet-piling members each arranged to present a concave face to the load thrust 2. A wall comprising a series of interlocking sheet-piling members each arranged to present a concave face to the load thrust, the succession of concave faces being non-concentric.

A. wall comprising a series of interlocked curved sheet-piling members, each arranged to present a concave face to the load thrust, the curvature of each member being non-conccntric to the area bounded by the wall.

i. A wall comprising a series of sheet-pit ing members havin concave webs and revei'selycurved interlocked edge portions, arranged to present concave web-faces to the load thrust.

5. A wall comprising a series of sheetpil terlocked, in combination with a backing arranged to support the members at the placeof interlocking.

6. A wall comprising a series of interlocked sheet-piling members arranged to present a succession of non-concentric concave faces to the load thrust, in combination with a backing arranged to support the members at the place of interlocking.

7. A wall comprising a series of metallic sheet-piling members having their meeting edges interlocked to permit of relative lateral displacement in driving, in combination with a backing of timber arranged to support the sheet-piling members at the place of inter locking.

8. A wall com rising a series of curved sheet-piling mem ers having their meeting edges interlocked, in combination with a skeleton backing arranged to support. the sheet-pilin members at the place of interlockin and leaving them unsupported at interme iate oints.

9. A wall comp'rising a series of sheet-pit ing members having "oncave webs and reversely-curved interlocked edge portions. ar-

ranged to present the concave Web-{aces to the load thrust, in combination with zi-skeleton backingarranged to support the slieetpilingmembers at the, place of interlocking 5 and leaving the wel) unsupported.

10. A wall eomprisin a series of curved metallic sheet-oiling members having their meeting edges interlocked to permit of Palm tive lateral displacement in driving, in com- 10 bination with. a skeleton backing of timber I arranged to support the sheet-piling members at the place of interlocking and leaving them unsupported at intermediate points. I In testimony whereof I have hereunto ailixed my signature. in the presence of two I5 Witnesses. i 4
