Sheet-Piling, of which the following is a specification. v

The invention relates to improvements in metahsheet-piling; and it consists in the novel features hereinafter described and claimed. I

The object of the invention is to produce a metal sheetiling of superior character and comprised o sections of novel form and construction, ada ting them for all theuses to which metal s eet iling may be put.

Among the speci 0 objects attained by my invention in its preferred embodiment it may be mentioned generally that the units or sections of my piling are strong, durable, and easily formed, that the sections are formed integrally with means whereby they may be locked together, thus dispensing with separate locking-flanges and the like riveted to the sections, that the sections are all alike in form and construction except where corners are to be formed, and that a wall of piling formed of the interlocked sections presents, in the preferred construction, on one side a substantially uniform surface.

The invention will be fully understood from the detailed descri tion hereinafter presented, reference being fiad to the accompanfying drawings, in which Figure '1 is a top edge view of a metal sheet-piling comprising sections embodying my invention. Fig. 2is a face view, partly broken away, of same. Fig. 3 is a detached top edge view of one of the sections of the piling. Fig. 4 is a top edge view of several sections of the piling and is presented to illustrate the formation of the corner-sections which may be required when the piling is-required to define angular outlines, and Fig. 5 is a top edge View of one of the corner-sections.

in the drawings, referring to Figs. 1, 2, and 3, the. individual'sections of'the piling are designated by the numeral 10, and these sections all correspond with one another and each is made from an integral plate of metal fashioned to form the web 11 and edge locking-loops 12 13 ,respectively, which referably both project from the same side of t e web, so that the piling when the sections are assembled may present at one side a substantially flat wall. The loops 12 13 are substantially cylindrical in cross-section, and both are formed by coiling the edges of the metal plate into the outlines shown, the right-hand edge of the plate being turned outwardly,-forming a short flan e14, and then coiled to form the loop 12, w 'ch projects beyond the righthand edge of the plate and is left partly open to form a mouth 15, adjacentto said flange 14. The 100 13 is formed by turning the left-hand e ge of the plate outwardly, forming a flange 16, and then coiling the metal in a direction toward the right to form said loop, which is preferably closed, or substantially so, as shown, and is of smaller diameter than the loop 12, but of greater diameter than the mouth 15 thereof.

The manner of assembling thesections 10 is illustrated in Fig. 1, in which it may be seen that the sections are driven one after another and that the loop 13 of one section is driven within the loop 12 of the next adj acent section, the flan e 16 passing through the mouth 15 of said oop 12. I preferably allow considerable freedom between the outer wall of the loop 13 and inner wall of the loop 12. When the sections are assembled, the adjacent loops 12 13 enter'into locking engagement with each other and resist any strains tending to separate the sections.

Figs. 4 and 5 are presented to illustrate the employment of the sections 10 in the formation of piling requiring an angular course, in which use of the sections I employ cornersections 17, havingthe webs 11 and loops 12 of the sections 10, andprovide on one edge thereof loops 18, differing slightly from the loops 13 of said sections '10 in that said loops 18 are formed directly on the edge of the web and that the flanges 16 are omitted, the Web itself passing through the mouth'of the loops 12, as shown at the upper and lower righthand corners of Fig. 4.

The sections 10 are all alike in every particular, and the loops 12 13 not only form integral locking members, .but by reason of their outline constitute means for stiffening the sections and enabling them to be readily driven. The form of the sections 10 also enables their productionfrom plate with convenience and Without undue weight or waste of metal.

If the loops 13 projected from the opposite side of the webs or in a direction oppositely .to the loops 12, they would cooperate with said loops 12'just as shown in Fig. 1; but in that event neither wall of the piling would be substantially flat or uniform, and therefore, Without in every instance limiting myself to the same, I prefer to have the loops 12 13 both projected from the same side of the web, as shown.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A metal sheet-piling composed of interlocked plate-sections each comprising interally a web, a loop on one edge thereof ormed byflanging the metal outwardly and coiling the same into loop form and leaving a narrow mouth of the-loop open, and a smaller loop on the opposite edge thereof formed by flanging the metal outwardly and coiling the same into loop form, thesmaller loops of the.

respective sections being adapted to be loosely inclosed in the larger loops of the respective adjacent sections and enter into lockin engagement therewith; substantially as set orth.

2. A metal sheet-piling composed of interlocked plate-sections each comprising inte-v grally a web, a loop on one edge thereof formed by flanging the metal outwardly and coiling the same into loop form and leaving a narrow mouth of the loop open, and a smaller loop on the opposite edge thereof formed by flanging the metal outwardly and ceiling the same into loop form, the smaller loops of the respective sections being adapted to be loosely inclosed in the larger loops of the respective adjacent sections and enter into locking engagement therewith, and said loops of each section being extended outwardly from the same side of the section; substantially as set forth.

8. A metal sheet-piling composed of interlocked plate-sections each comprising inte- 'rally a web, a loop on one edge thereof formed by coilin the metal into substantially cylindrical form and leaving a narrow mouth of the cylinder open, and a smaller 100 on the opposite edge thereof formed by coi in the metal into substantially the form of a closed cylinder, the smaller loops of the respective sections being adapted to be loosely inclosed in the larger loops of the respective adjacent sections and enter into lockin engagement therewith; substantially as set forth;

4. A metal sheet-piling composed of interlocked sections each comprising integrally a web, on-one edge of which is formed a flange 14: and partly-open loop 12 formed by coiling the metal plate in a direction from and beyond said web, and on the other edge of which web is a flange 16 and loop 13 formed by coiling the plate in a direction toward said web, the smaller loops of the respective sections being adapted to be inclosed within the larger-loo s of the respective adjacent sections an enter into locking engagement therewith; substantially as set forth.

Signed at New York city, in the county of New York and State of New York, this 6th day of September, A. D. 1906.
