In the accompanying drawings -Figurel is a plan of several sections of sheet piling constructed n accordance \Vltll myamvention and coupled together for angular movement one with relation to another. F ig..2'

is a detail perspective view of hue end portion of one section or sheet of piling embodyin'g a modification. Fig. 3 is a plan showing a number of sections of my sheet or sectional piling arranged to form a hollow column.

In accordance with my invention, each sheet or section 1 of my improved piling is formed of steel or other suitable metal and comprises a web of suitable length, breadth and thickness and coupling heads 2, 3 at opposite side edges thereof and formed preferably integral therewith. Each coupling head comprises a pair of oppositely extending arcuate jaws 4:, 5, which are equally semi-circular and which form an opening (3 between their outer ends. 'The jaw 5 is of less radius than the jaw 4 but is concentric with reference thereto and at the inner end 'of said jaw 5 is a shoulder 7 which is disposed transversely with reference to thegenoral plane of the web, is at an angle other than a right angle to that of the general plane of theweb and on the side opposed to the larger jaw 4, forms a flange 8 the inner side 9 of which is curved and is concentric to and spaced frointhe larger jaw. The jaws of the respective heads at opposite side edges of the web of the piling are reversely disposed so that the smaller jaw of each head is adapted to enter the space between the larger jaw and flange .8 of the next opposing head as clearly shown in Figs. 1 and 3 of the drawings. The width of the space (3 somewhat exceeds the thickness of the web Specification of Letters Patent.

of; the piling and as will be 'noticed each smaller arm is free to play bothangularly and also to some extent transversely in the space between the larger jaw and the flange 8 between which it is located and the oblique disposition of the outer surface of the shoulders 7 also permit of such playfand hence the sections'are'fleXibly coupled together so that they may be disposed angularly with reference to each other and such flexible conhections between the sections nor sheets greatly facilitate the driving thereof and allow of slight, deviation from the straight line in driving the piles. L

It will be apparent that the piles may be driven either in line with one another or angularly and hence they may be so disposed as to form a caisson, hollow column or other structure. k I

Thejaws of the respective coupling heads while permitting of angular or lost motion between the sections or sheets interlock to effectually connect and secure the sheets or sections together. In such instances as'may make itnecessary, the spaces between the members of the coupling heads may be filled prevent-leakage between the joints and this will be found especially useful in using the improved sections or sheets for constructing caissons and the like.

The webs of the sections or sheets may be straight as shown in Fig. 1 or they may be bent as shown in Figs. 2 and 3. Other modifications may be made within the scope of the appended claims and I do not there- 'fore desire to limit myself to the preciseconstruction and arrangement of devices herein shown and described.
