Moreover it is of no importance whether the joinings are positioned at the exterior or at the interior of the Wall and whether one or several piles are joined simultaneously.

What I claim to secure by Letters Patent in the United States is:

1. Anchoring device shiftable from above for sheet piling walls comprising projections at the piling forming between them a groove, the said projections being made of one piece, and an anchoring member adapted to engage and slide into the groove, the said anchoring member extending over a certain length of the groove.

2. Anchoring device shiftable from above for sheet piling walls comprising projections at the piling forming between them a groove, the said projections being integral with the piling, an anchoring member adapted to engage and slide into the said groove, the said anchoring member extending over a certain length-oi the groove, and means pivotally connected with the anchoring member to actuate said member.

3. Anchoring device shiftable from above for sheet piling walls comprising a grooved member secured to the piling, a connecting member having a beaded head portion adapted to engage and slide into the groove of the said grooved member, the said connecting member being extended over a certain length of the grooved member, and an anchor joined to the connecting member.

4. Anchoring device shiftable from above for sheet piling walls comprising projections on the piling forming a groove between them, the said projections being integral with the piling, a connecting member provided with a beaded head portion adapted to engage and slide in the said groove, the said beaded head portion being extended over a certain length of the groove and rounded ofi at its lateral faces so that the connecting member may be turned in the groove about a longitudinal axis, and an anchor pivotally connected with the said connecting member.

5. Anchoring device shiftable from above for sheetpiling walls comprising two grooved members welded to the piling, two connecting members each having a beaded head portion adapted to engage and slide in the groove of one of the grooved members, the said beaded head portions being extended over a certain length of the grooved members, and a single anchor pivotally connected with the two connecting members,
