The known anchoring of the irons of sheet pilings has sometimes the disadvantage that peculiarly in such constructions where the soil behind the sheet-piling is subsequently filled up, the anchoring members which hold the girder rearwardly are strained in a disadvantageous manner due to the setting up of the filling. In order to remove this inconvenience it has indeed been attempted to provide joints inwardly of the anchor, but it has not succeeded in transmitting the stresses of the anchor in such a way as to strain advantageously the anchor. Moreover it is very often requested to pass about existing obstacles without shifting the regular distribution for the points of application of the anchor in the girder.

According to the invention the disadvantageous stresses of the anchor are avoided by providing a joint in the girder, this joint allowing a reliable turning of the anchor in the perpendicular plane of the same. In order to pass about existing obstacles the joint is formed as a cross-joint :so that the anchor is pivotally movable in all di- 'rections.

The annexed drawing shows, by way of example, a form of embodiment of the invention.

In this drawing,

Fig. 1 is a schematic View of the anchoring device,

bolt e pivotally mounted between two U-shaped irons a.

Either of these U-irons are attached to the sheet-piling in a known way.

The pivotal axes of the cross-joint piece which are disposed perpendicularly to each other may be formed by two bolts which extend through i the body of the cross-joint and must be relatively disposed by at least the sum of their radii in order to pass by each other (see Figs. 2 and 3) or one pivotal axis may be formed by two pins pro- :truding-from the body of the cross-joint while the other axis is constituted by a bolt passing therethrough. In the latter case, the two pivot axes perpendicular to each other need not be relatively disposed but may intersect each other. Also in the latter case the connecting-piece f will be either movably or rigidly attached to the anchcr 9.

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

l. Anchoring device for sheet-piling, consisting of a girder transversely attached to the sheetpiling, a cross-joint-piece pivotally mounted in the said girder, a connecting-piece pivotally connected to the cross-joint-piece and an anchor inovably attached to the connecting-piece, the pivotal axes of the cross-joint-piece and the connecting-piece being perpendicular in relation to one another.

2. Anchoring device for sheet-piling, consisting of a girder transversely attached to the sheetpiling, a cross-joint-piece pivotally mounted in the said girder, a connecting-piece pivotally connected to the cross-jointpiece and an anchor movably attached to the connecting-piece, the pivotal axes of the cross-joint-piece and the connecting-piece being perpendicular in relation to one another, while that of the connecting-piece and the anchor the parallel.

3, Anchoring devicdor sheet-piling, consisting of a girder transversely attached to the sheetpiling, a cressrjoint piece pivotally mounted in the said girder, a connecting' piece pivotally connected to the crossjoint-pice and an anchor movably attached to the connecting p'iece', the said girder consisting of two U-irons attached with their one flange to the irons of the sheetpiling and enclosing between them the crossjoint-pieces of the single anchors.

e. Anchoring device for sheet-piling, consisting of a girder transversely attached to the sheetpiling, a cross-ioint-piece pivotally mounted in the said girder, a connecting-piece pivotally connected to the cross-joint-piece and an anchor movably attached to the connecting-piece, the said girder consisting of two U-irons attached with their one flange to the irons of the sheetpiling and enclosing between them the cross-jointpieces of the single anchors, positioned at the girder in desired spaces from one another and independent on the spaces of the irons of the sheet-piling.

5. Anchoring device for sheet-pilings, consisting of a girder attached to the sheet-piling, a cross-joint-piece pivotally mounted in the said girder and an anchor pivotally connected to the cross-joint-piece, the pivotal axes of the crossjoint-piece and of the anchor being perpendicular in relation to one another.

6. Anchoring device for sheet-pilings, consisting of a girder attached to the sheet-piling, a cross-joint-piece pivotally mounted in the said girder, a connecting-piece pivotally connected to the said girder, a connecting-piece pivotall'y' con nected to the cross-joint-piece and an anchor rigidly connected to the connecting-piece, the pivotal axes of the cross-joint-piece and of the connecting-piece being perpendicular with relation to one another.
