INTERLOCKING SHEETING.

Specication of Letters Patent. Patllted July 22, 1913. Application ledoctober 14, 1912. Serial No. 725,680.

T0 all whom it may concern Beit known that I, FRANK WY. SKINNER, a citizen of the United States, residing at No.4l Sherman avenue, TompkinsvillqNeW Yorlnfhave invented a newand Auseful Jform of steel or iron interlocking.sheeting for use` in Cotter-'dams and caissons, to inclose excavations, to exclude or retain earth and point of being prohibitive foremany places' wherelightZ cheap and eflcient sheet piles are desirable.' Most `of the few types of' sheet piles now on the market in the United States, are made in only'tivo or three widths and have vwide clearances in their joints that prevent them from being watertight unless great pains are taken to calk thenivor they become silted up.

My invention gives a pile unit of any Width, thickness and weight required, that is fabricated simply,` quickly, and'cheaply from a single sheet byvinerely ybending it Without riveting, and that is lighter and 'easier to handlethan-most other types, that" is especially adapted to short lengths and easy driving where tight continuons strucn f tures are the principal requirement, and that can be fabricated much more cheaply than any other section not completed in the rolls. `When made oi heavy sheet metal or plates, these'ples may be driven directly by hammers in the usual manner.l It' their thickl ness is very small so that they can not en# dure heavy hammering directly on the pile tops, they may-be driven by driving bars described in my Patent 842,120 and are es- The drawing is a cross section of a sheet pile unit having a channel-shapecrosssection with double flanges integral With 'the Web, with their short legs both toward the` center of the Web. and the Web extending across the spaces between the legs of each flange.

In the drawing l is the web, and 2 and 3, are respectively the long and short legs of the double fianges. The dotted lines represent part of the outlines of duplicate pile sections in reversed position with one denble flange of each engaging and interlocking `with a double flange of the unit shown by 'full lines. type of cross section, namely a straight web .with double flanges substantially at right angles with it, and having substantially par allel legs. My invention covers any Vcross section having two dou-ble flanges intersecting the web with the short legs of Jthe `flanges between the long 'legs and the center of the web. The web may be straight,

bent, curved, plain or'ribbed, or of any suitable cross section, and the flanges niay make any angle With thevveb and the cross section of thedonble iianges may have any suitable shape, and may be alike or different yin both flanges, and the tivo legs of either vflange may beA parallel or convergent or di vergent, and may be curved or straight.

I claim as my invent-ion, l. A sheet pile unit symmetrical about its longitudinal centerline, and having tivo longitudinal flanges integral with, and ap- 'proximately at right angles to the web, each iiange bent nearly double on'a longitudinal line near itscenter and with the short legs This figure shows the simplestV 'on'th'e insides of the ilanges, toward the cenl ter line 'of the unit.4

Q. A sheet pile unit with two double longitudinal ianges each of which has one long leg integral with the web and makingr an angle Awith it, and a short legiutegral With the long leg and on the side of the longf leg toward the center of the pile and toward the other flange. M
