SHEET-METAL rILme. 1

Application filed January 15, 1926; Serial No. 81,396.

The invention relates to rolled sheet metal piling, and particularly to the box type, in which each pile is made up of two oppositely turned sections or shapes of U-form in cross section, riveted together at their meeting edges, which are turned laterally for this purpose. The invention has for its principal objects the provision of. an improved pile of the type specified; (1) in which all of the parts making up the pile may be rolled without any difliculty by ordinary methods; (2) in which an accurately fitting interlock is insured at the meeting edges of the piles; (3) which is adapted to be rolled is a similar view showing a slight modi cation. And Fig. 3 is an end view of the interlocking shape.

Referring to the drawings, A, A, A are three piles all similar, arranged in interlocking. position. Each pile consists of a pair of

opposing U-shapes

1, 1 having their

opposing flanges

2, 2 turned outward, and a pair of

interlockingshapes

3, 3, one at 1 each side ot the pile.

The

shapes

3, 3 are similar, and are rolled members each comprising a flange 4 (Fig.

- 3) and an interlock consisting of the tongue 5 and the hook 6.. The interlock itself is 7 that shown and described in my Patent No.

1,543,676 of June 30, 1925; The flanges f the shapes 3 3 fit between the opposing flanges 2, 2-0% the

shapes

1, 1, and the parts are rigidly secured together by the rivets 7 7 one line only of which is shown, but it will be understood that by providing longer flanges to give the necessary space, more lines of rivets may be-used, if desired. The

- pile is symmetrical with respect to its axis The neutral axis of the pile lies approximately upon the center line 0:, a: of the wall, in the Fig. 1 construction, being only slightly below such line due to the fact that the hooks 6 6 which lie below the neutral axis have. their. centers of" gravity slightly .any practical requirement.

further from the center line as, wthan the centers of gravity of the tongues 5, 5. This is practically negligible, but is corrected in the Fig. 2 construction, in which the

shapes

3, 3 at the two sides of the pile are reversed in position, the hook 6 lying below the center line it, w on one. side'ot the pile, and above it on the other side. Otherwise, the arrangement of Fig. 2 is identical with that of Fig. 11

The great advantage of the pile just described is the ease with which the diflerent parts may be rolled in the mill and put together in the shop. The interlocking pieces are narrow and light members easily rolled and formed in the'mill and easily handled in the shop, while the main U-shapes are entirely devoid of any parts requiring spe-- cial care in rolling or handling. Variations in the widths of the main shapes and in the widths of the connecting web of the interlocking pieces are easily taken care of .in locating the rivet lines in the shop and in no way aflect the accuracy of the interlock,

while the distancebetween the centers of the latter may easily be made very accurate.

A further important advantage is the fact that by spreading the rolls the thickness of the main U-shapes may be gauged to suit As the interlocking pieces are rolled separate these are not afiected thereby, whereas, if they Were an integral part of the main shape, spreadin the rolls would become impractical I hat I claim is:

1. A pile comprising a pair of opposin rolled U-shapes with out-turned flanges, an I an interlock at each side of the pile comprising a rolled shape with a flange at its inner side secured between said out-turned flanges and an interlocking device atits outer side. 2. A pile comprising a pair of. opposing rolled U-shapes with out-turned flanges, and an interlock at each side of the pile comprising 9. rolled shape with-a flange at its inner side secured between said out-turned flanges and an interlocking device at its outer side, the said interlocks at the two'side's of the pile being counterparts.

.3. A 1le comprising a pair. of opposing rolledv shapes with out-turned flanges, and an interlock at each side of the pile comprising a rolled shape with a flange at its inner side secured between said out-turned i flanges and a tongue and hook interlocking device at its outer sidelying in part on one device at its outer side. side of the neutral axis of the pile and in 10 4. A pile comprising a pair of opposing part on the other side of said axis.
