movement and providing'for lateral detiec tien of the several connected.

The particular object of the invention is to provide a construction whereby the edge of one pile will. be Vengaged by the other'l to piles of a. series when "provide a strong flexible joint., preventingI the spreading' of the holding elements and counter-acting the various strains to which constructions'r of this class are subjected in use; and especially to provide a construcion wherein interlocking engagement is maintained by (Jo-acting hook elements and embracing elements respectively, of adjacent piles.

f Heretofore in steel piling wherein one oi the edges is engaged within or between the embracing edges of the next adjacent pile, strains tending to separate the piles have caused the said elements to open or spread, and one of the objects of my invention is to so construct the pilesas to pro-.

vide l'ieariizf.;` edges which are so arranged as to oppose spreading strains at the `mirious I uns which the piles may assume with relation to each other.

The present invention embodies improvements over that shown in my prior applicaion filed September 9th, 1908, Serial No. maar. Y

in the drawings accompanying the specification: Figure l is a cross sectional view .showing a plurality of piles assembled, each being provided with 'interlocking terminal edges cti-acting with the appropriate edges of adjacent similar piles. Fig-2 is a similar view showing an ampliiication of the construction of l. v

Generally stated, each pile consists or a icngitudinal web portion 2 having boundary edges arranged to telescopieally interit and tio-act with the edges of adjoining piles. n

Patented-Feb. 9, 1.909,

the construction shown in Fig. 1 the web 2 is provided at one of its edges with enlargements 3, 4f, partly cylindrical in form, both inside and out, having gradually reduced tapering body portions rounding outwardly at each side and toward their terminals 5, 6. As shown, one of said terminals l5 gradually tapers to its rounded terminal edge without substantial 'variation of the inner and 'outer cylindrical curvature, while the ther terminal (i is similarly tapered but is abruptly dellected inwardly, beyond an intervening receiving` cavity, .so as to, provide a retaining longitudinal edge flange forengagement with the terminal edge of -a coaeting pile coifistructed as is the other edge at the lett side of Web 2. Said edge vof such co-acting pile or of the .otherside of 'the same pile, terminates in a tapering rearwardly deflected retaining longitudinal edge flange 7, with a similar intervening rcavity adapted to snugly receive the terminal edge (5, and a rounded body portion 8 at one side adapted to bear against embracing terminal portion 5. -The other side of suchedge portion'ot the inter-fitting pile is bulbously extended as at 9, to embrace or 'partly embrace the outer rounded portion of terminal 6, as will be readily understood. The coacting hook terminals 6 and 7 are preferably located substantially in alinernent with the web 2 of the pile, or approximately 'so and suliiciently olii-set therefrom, so that When engaging each other as shown, the separating strain will be counteracted approximately in the plane of the webs when in alinement or substantially at the middle portion of-the jointin any position. As thus constructed it will be seen that the hooked elements of the adjacent edges of connected piles will interfit with each other;

that ample space is provided inwardly .be-

parts in rigid engagement when set, While permitting liexibility or aejustnient and insuring practically 'Watertight joint throughout.

In Fig. 2 I tion of the construction shown in Fig. l, in Whichl the interlocking piles are of substantially the same cross section, being merely made in riv'ht and left hand forms at the respective edges of the pile. 'In such construction the Web 2 is provided at each of its edges With dividedenlargements 3, Il', partly cylindrical in forni having gradu-- allyl reduced tapering body portions rounded outwardly at each side and toward the terminals 5', 6. 'As shown one of said terminals 5 gradually tapersA to its rounded terminal edge Without substantial variation of the inner' and outer cylindrical curvature, While the other terminal 6 is similarly tapered but is abruptly deflected inwardly sc as to provide a retaining'.longitudinal edge' iiange for engagement With the corresponding edge liange of a co-acting pile of similar Storm. As thus constructed and in- 'terfitted'it Will be seen that the hooked ele'- 'ments of the adjacent edges of connected piles Will interlit With each other in the' same general manner -as has been described as to the construct-ion oi' `Fig. l and that the embracing termina-ls 5 at `leach side Will maintain the parts vin braced engagement,

counteracting any strains tending to open up or separate the operating parts, While.

providing uniformity olf construction of the -pile at each edge, and permitting the piles to be interchangeably inserted at either end.

WT ith either construction it will be seen that, due to the inwardly turned terminals and outer bracingporti'ons oi the engaging edges, the interfitting holding elements will be rigidly retained under pulling strains at Whatever'A position the parts may assume. Also that the interiitting hooked terminals 'and 7 or 6 and 6 will be inclosed Within the receiving cavities of the other pile, pro

viding rounded bearing faces at all posh' tions and eiiiciently performing the fund' tions intended.

The. pilee are of simple construction; they may bev readily rolled inpropcrly designed rolls, either entirely, or partly by rolls-and then inished by suitable dies or other niachincry.v The Adisposition of the metal is such as to secure the best results While the prevention of joints will be Wound to avoid the common have illustrated an amplicaspreading or opening oi the' nacer l. A rolled metal ile having at its edge a backwardly turned caring terminal and a vreceiving recess for a corresponding element of a co-actlng pile, and an outer embracing portion adapted to engage the backwardly turned bearing terminal of a similar co acting pile, substantially as set forth.

2. A- rolled metal pile consisting of a web provided with a divided edge portion having a backwardly bent bearing portion terininating in a plane substantially in the plane of the web.

' 3. A rolled metal ile consisting of a web provided With a divided edge portion having a backvvardly bent bearing portion terminait ing in a plane substantially in the plane of the Web, and having a receiving recess for a corresponding element of a (5c-acting pile, substantially as set forth.

A rolled metal pileccnsistineA cita web provided with a divided. edge portion having a backwardly bent bearing portion terminating in a plane substantially in the plane of the web, and having a receiving recess for a4 corresponding element of a cti-acting p1le and 'an embracing portion adapted to engage the backwardly turned bearing terminal of a similar co-acting pile, substantially as set forth.

5. In rolled metal piling, the combina-4 tion ot inter-engaging piles each having a backwardly bent hooked bearing terminal,

an outer embracing portion adapted to enn gage such terminal of the other pile', and an intervening cavity to receive such. terrnii'ial,
