SHEET PILING.

Application `filed January 29, 1927. ySerial No. 164,504.

This invention relates to sheet piling of c the interlocking type and, specifically, con- I am aware.

sists of sheet piling composed of identical trough-shaped elements, the longitudinal edges of which are so shaped that theelements can be interlocked and separated laterally, instead of being threaded together longitudinally as usual, and that the elements can be alternately reversed to face in opposite directions, if desired.

This new form of sheet piling, usually made of rolled steel sections, possesses several material advantages not `found in prior forms of interlocking sheet piling, as far as These advantages are due to the following features of its construction: l, the trough shape of the elements, which gives the greatest rigidity possible for a given amountof metal; 2, thepeculiar shape of the interlocking edges, which permits theL lateral engagement and separation of the elements, and also the reversal of alternate elements; 3, the shape of the interlocking edge having the socket for the reception of ytheT head edge of the adjoining element,

whereby the projecting lip, which has to be bent inwardly subsequently to thev rolling of the section, can be made much shorter than heretofore, which facilitates the rolling operation and the bending operation and renders said lip muc-h less likely to be distorted by hard material in the driving of the pile.

I am aware that sheet piling capable of being interlocked laterally has heretofore been proposed, but in no instance of which I am aware, can alternate sections bey reversed in position and still be laterally interloclzed and separated. The alternately reversed position of the elements is very desirable'because it imparts the greatest possible stiffness and strength to the piling wa l.

The invention is illustrated in the accompanying drawing, in which Fig. l is a crosssectional view of a piling wall composed of the in'iproved elements arranged in reversed position; Fig. 2 is a partial elevation Vof ythe same and Fig. 3 is a cross section like Fig. 1 but with the elements not reversed.

In these views, the pilingwall is composed of identical trough-shaped elements or Sections 1, each ofwhich is anged along its longitudinal edges, one fiange carrying the male T head 2 and the other the female socket head 3. These sections are rolled to inished shape, with the exception of the lip 4, which is subsequently bent over, as shown,

to complete the socket and retain the T head of the adjoining section while permitting its being laterally engaged andV disengaged. Said lip is relatively short, so that it 'can be formed in the rolling operation without the necessity of a deep groove in the rolls. The T and socket heads are so formed, as will be apparent from the drawing, that all the sections may liey on the same side of the vertical plane passing through the interlocking edges, or that alternate sections may vlie on opposite sides of said plane, as shown in Fig. l. As beforestated, the alternate arrangement is preferable, on acount of the great rigidity thereby`r obtained but, where the available space is insufficient .for the reversed arrangement, the sections may be interlocked in the same relative position, as shown .in Fig. 3. I

Piling thus constructed is, to a `certain degree, fiexible, the interlocking edges permitting some angularity between'the sections. It is economical to manufacture, easy to install and disassemble, and gives thev greatest posible rigidity for the weight of metal use Having thus described my invention, what I claim is: l. A retaining wall of Asheet piling, comprising a plurality of identical troughshaped rolled sections, each section having a rounded Tv head on one edge and an open mouth socket on the other edge, whereby the lsections can be engaged laterally and the front and back depth'of the wall can be doubled by reversing alternate sections.

2. A sheet piling unit consisting vof a channel section flanged on its edges, one of said flanges carrying a head of rounded T shape and the other flange carrying a projecting claw and an extended lip, the latter being bent over to form, withA said claw, a socket in which the T head of an adjacent sectioncan be engaged by lat-eral entrance, whether said adjacent section is in the same relative position as the first section or is reversed relatively to the same.A

In testimony whereof I have hereunto set my hand.
