SHEET-PILING.

..- Specification of Letters Patent.

3 Application filed June 15, 1912. Serial No. 703,865.

To all whom it may concern:

Be it known that I, GEORGE WILLIA MO- FARLANE, a citizen of the Dominion of Canada, residing at Paris, in the county of 5 Brant and Province of Ontario, Canada, mechanical engineer, have lnvented a certain new and useful Improvement in Sheet-Pil-.

ing, of which the following is a full, clear, and exact description.

My invention relates to sheet metal iling, and its object is to provide sections 0 great resisting power to .a lateral strain, and which may be locked together either' in straight or curved lines, the interlocking means being designed with a view to the easy withdrawal of the sections when their usefulness at any point is ended.

Referring to the drawing in which simi-. lar letters and, numerals refer to sim lar parts throughout, Figure l is a cross section of a pile, with portions of the neighboring piles with which it interlocks. Fig. 2 is an elevation of one section of the piling.

-. Each section of the piling consists of a web portion A, a ball portion B and a socket portion C. The web portion A, I prefer to wave or corrugate longitudinally, the corrugations being shown as l in both figures. It is a Well known fact that the corrugating of a metal adds greatly to its resisting power when opposed to a strain exerted at right angles to the direction s'n which the corrugations run, but this has been, not to my knowledge, applied to the manufacture of sheet metal piling. A further advantage is secured by the corrugation of the sections, in that a lighter weight of metal may-be used than if uncorrugated, yet the some 4 or even greater strength be secured and at 40 a much less cost for material and handling. For the formation of the ball and socket portions 'of the pile, the opposite edges of the web A are asit were split into two wings, those forming the ball portion B being shorter .than those forming the socket portion C. The wings 2 and 3 of the ball portion B extend away from each other and diagonally away from the web for about half their length at which point they are Q-turned'in toward each other, their extremities 4 and 5 being however separated by the opening 6, thus forming a practically diamond shaped inale member.

The formation of the female member C is similar to that of the male member B both being dl. *a ond shaped, the interlor of the tion.

.means of which a member being of a size suflicient to recelve the member B of an adjoiningpile t escopically and to coact therewith in the 1 r'mation'of a range of piling, the extremities 7 and 8 of the member C being. brought 'sufliciently close to each other to prevent the withdrawal, of thefmember 'B irom the but a longitudinal. direcmember C in any n will be noted that the ba'll portion B1 fits the socket portion 0 Very loosely; and. that the diamond shape-of each admits ofa certain amountzof rotation of the part B Within the part 0 so that a considerable wall formed of a series of the "interlocked sections. This is shown in the position the part B has taken in relation to the part C.

I have found the diamondshape to be a very preferable formof interlock, the contact between the male and female members being thereby reducedtm amere point, so that the riskof these being kept apart by grit or gravel, therebypreventing a water tight joint isreduced' to ga'ininimum, also, the fact that the contact of the parts in the interlock is so small greatly facilitates the drawing of the piles when they'have served their purpose at any given point.

It is preferable't-hat the parts be rolled integral from a single ingot of metal.

The dotted member D is introduced to show the meansof attaching a range at right angles to the main wall or as a means of turning the main wall when a rectangular inclosure is desired.

9 indicates an aperture in the web A bypulling means may be attached to the pile.

Having thus-fully described my said invention what I claim is 1. A rolled metal pile having a corrugated web, and divided terminal edges, the edges at one side of said web forming a hollow diamond. shaped male member and those at the opposite side a hollow diamond shaped iemale member said members being designedto slidably interlock withv the corresponding parts of .piles of similar construction.

2. In rolled sheet tal piling, the combination of similar sections, each section betermite edges, the divided edges on one side ofthe :veb extend ng diagonally away from 2o amount of angling would be pbssible in .a

theweb for a portion of their length, then apprcachin each other to form a hollow diamond shaped male member, and the divided edges at the other side extending diagonally away from the web for a portion of their length then approaching each other to form a hollow diamond shaped female memberfadapted to receive the male member of an adjacent section and slidaloly interlock therewith.

3. In rolled sheet metal piling, the combination of'a plurality of similar sections, eaclrcomprising a longitudinally corrugated web, having divided terminal edges, the di znoeanet vided edges on one side of the web forming 5 a hollow diamond shaped male member, and those on the other side a hollow diamond shaped female'member adapted to receive the male member of an adjacent section and allow of a certain amount of rotation therein whereby a wall being constructed by the interlocking of said sections might be defiected from a straight line.
