INTERLOCKING- SHEET-EETAL FILING.

Specification of Letters Patent.

Patented l eb. is, 1909.

Application filed April *1, 1908. Serial No. 425.668.

To all whom it may concern:

Be it known that I, SLATER '1. Franc, a citizen of the United States of America, residingat Pittsburgin'the county. of Alleghenyand State of Pennsylvania, have inments in Interlocking Sheet-Metal Pilings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to interlocking sheet metal piling, as -ordinarily used in the construction of abutments, piers, retaining 'walls, cofferdzgms and submarine structures.

The primary object of tins invention is to provide a novel reinforced interlocking piling of a light, durable and rigid construction.

A furtherobiect of this invention is to provide interlocking'pilings that can be easily manufactured and assembled.

To this end, I have devised a sheet metal piling having longitudinal reinforcements and hook-shaped interlocking edges, said edges being constructed "to maintain the pilings either in a common plane or intwo parallel lanes with said pilings alternately arrange in parallel planes.

The detail construction entering into my invention will be presently described and then specifically pointed out in the appended claims.

In the drawings :-Figure 1 is an'end view of an interlocked reinforced pilingconstru'cted in accordance with my invention, Fig. 2 is a similar vlew of a slight modlfication, Fig. 3

is an end view of a'portion of the piling, il ustrating the formation of the edge thereof, and Fig. 4 is an end view of another modified In the accompanying drawings, 1 designates a sheet of metal provided with angularly. disposed hook-shaped edges 2 and 3, the edge 3 being disposed at an angle oppo site to the edge 2 and in a plane parallel therewith. The sheet of metal adjacent to the hook-shaped edges 2 and 3 is provided upon both sides with longitudinal ribs or reinforcements 4 and 5, these ribs or reinforcements extending from one end of the sheet to the opposite end thereof, with the ribs or reinforcements 4 opposite the ribs or reinforcements 5.

The manner of interlocking two pilings constructed in accordance with m the drawings, where two hook-shaped edges are interuseful Improveinvention looked. it will be observed that the ribs or reinforcements confronting the groove 6, of the'hook-shaped edge prevents the connectingl hook-shaped edge from beingdislodged, 0t er than by a movement longitudinally of the piling, and when the pilings are connected together to reinforce a partition or wall constructed of concrete, the concrete is adapted to enter the small space between the 5 interlocking edges and prevent one piling from moving with respect to the other.

In Fig. 2 of the drawings, I have illustrated a piling wherein the hook-shaped edges 3 lie in planes at right angles to one 7 another, said hook-shaped edges being disposed upon one side of the vertical plane of said piling. In other respects the piling of- Fig. 2 is conformable to t e piling of Fi 1.

A modification of my invention is i ustrated in Fi 4 of the drawings, wherein the hook-shape edges 7 are in a plane parallel with the body of the piling, these hookshaped edges being of a slightly different roduceamore snug so" shapein cross section to connection between ad]oining pilings. in sections of this formation, adJoinim pilings will be alternately arranged in paralle planes. As will be understood by reference to the drawings, consists of three parts, viz. the main or body portion (the portion located intermediate the planes of the laterally-extendingribs). and the two edge portions located on the opposite or outer side of'these rib planes. 9()

, Each edge portionin cross-section consists of a return bend, one of the arms of which (the inner) is integral with the ribs, the two arms being substantially-parallel with each other, the two arms being. oined by a curved portion, the whole forming a hook-shaped portion one end of which is joined tothe body portion of the sheet, the curved portion forming one of the side edges-of the sheet. The planes of the arms of the cross-section) are angular with respect to a plane extending at right angles to the plane of the body portion in similar section, in contradistinction to a structure in which thehooks are formed by placing a return bend on 105 il sheet in cross-section 85d edge portions (in f the substantial parallelism of 1 14 thelength of the edge portion and has for its, Walls the inner faces ofthet'wo arms and the similar'face of the curved connecting portion, thereby formii'i'g .a groovewhich (in crosssection) is closed at one end and has substantially parallel side Walls. The groove is not closed at the point of juncture of the arm and rib structure, the free end of the opposite (the outer) arm being spaced from the rib a distance sufiicient to provide an open end for the groove, said end belng 1n opposition to the closed'end of the groove and adjacent the outer faceof the rib toward which the open end of-the groove (the rib 4, for inthe outer arm of the edge portion extends.

By reason of the fact that the inner Wall of stance in Fig. -3) extends at a substantial right angle to the plane of the body-portion (said wall being provided to prevent a withdrawal movement of the'interlocking edge ortions in onedirection), the actual opening the groove.

' or .the groove is at the point of shortest disdrawings, the line of shortest distance which forms theactual opening to the groove is of greater length than the line of shortest distance between the side walls (the width) of Inasmuch as the arms of-the edge portions extend angularly with respect to and tending toward a planeextendlng at right angles to the plane of'the bodyportion, the groove necessarily extends in similar angularity, and

as its 0 en end is adjacent the rib structure,

it will e readily understood that such open end is located at the inner end of the groove, and such inner end is located at a point be tween its outer end and the body portion of the sheet. And while the grooves are 10- cated intermediate the side edges of the sheetformed by the outer faces of the curved connecting portions of the hooks, the outer or closed end of each groove extends to a point closer to the adjacent side edge than the in ner or open end of the groove, so that it will be obvious that the groove extends to a point between its open end and such side edge of the sheet.

By reason of the construction shown, the groovein cross-sectionis closed at all points excepting at its inner end, so that any lateral strains of the sheet will be placed on the free edge of the bend and the part of the bend of the adjacent sheet which opposes said free edge, as in each of the forms'shown while the form shown in Fi s. 1, 2 and 3 provides the additional oblique surfaces to aid in resisting the strain.

I claim as new, is

- In the manufacture of my piling, .the extensions of the body of the piling, as illustrated in dotted lines in Figs. 2 and 3 can be bent to produce' the hook-shaped edges by .tWo or more passes between rolls, it being preferable to roll/ the hook-shaped edges as illustrated in dotted lines in Fig. 3, and then produce a completeedge by another pass of the piling, although the passes may beicontinuous. r

It is apparent that when'a partition or wall is constructed of ,aplurality of myilings connected together, that considera le rigidity will be maintained capable of With-. standing internal and external pressures, and that when properly assembled, a plurality of durable interlockin .hnits willbe providednot easily separated by shearing, or similar stresses to which the iling may be subjected,
