Specification of Letters Patent. Application filed September 22, 1905. Serial No. 279,644

Patented. Jan. '8, I907.

To a, whom Lt may concern: 3

I Be it known that I, J ULIUsR. WIIMLINGER;

a'citiz'e'n of the United States, residingat Brooklyn, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Metal Filing, :of which the following is a specification.

My invention relates to metal pilings and the object of my present invention isto provide a piling construction which may be used for driving concrete or other piles or for any purpose to which sheet-piling is adapted.

My improved piling construction comprises a structure formed of metal sheets,

preferably corrugated and secured together in pairs in such a manner that they may be driven bodily. The sections thus formed are provided at or near their ends with means for locking the adjoining sections. For the sake of clearness I will hereinafter refer to these sections as piles.

Referring to the drawings attached hereto, Figure 1 is a transverse sectional plan of a single pile formed of two corrugated plates secured together. Fig. 2 is a transverse sectional plan of a portion of two piles locked together. Fig. 3 is a transverse sectional plan of a portion of two piles driven at an angle to each other and locked at their intersection.

In my improved metal-piling construction each unit or pile is formed of two corrugated plates or sheets each having semicircular bends or corrugations 1 and flat portions or webs 2 between the said corrugations. The sheets are so fastened together that the corrugations will face each other and form cells 10 10, having substantially circular crosssection; but they may have any other suitable cross-section. They are secured together by means of rivets 12 12, which pass through the webs 2, the two sheets being thus brought into contact with each other. Two sheets thus form a unit or pile. These piles are locked to the adjoining piles when in position of use. The corrugations 3 at one end of each unit are of a smaller radius than that of the corrugations 1 at the other end by the thickness of the material used in order that when the piles are driven in locked position the eell formed by the corrugations 3 will readily fit and slide within the cell formed by the marginal corrugations 1, as

' shown in Fig. 2. If, however, the material of which these piles are manufactured is sufficiently thin, the bends or corrugations may adjoiningunits maybe done either by eX' panding thecorrugations 1 orflby compressing the corrugations o'fthe iadjoining unit enough to allow the end of the unit to bein-' serted, as will be readily understood.

The web 2 adjacentto theco'rrugation 3 at the end of each unitis. provided with ,a look.-

ing member composed of a fiat portion, {1 and "a curved portion 5 at an angle thereto; Thev locking members are secured to the body-of the pile by means of rivets 12 12, which pass through the flat portions 4 and the webs 2 of the plates. The curved portions 5 overlap and lock the edges of the corrugations 1 of the adjoining pile, as shown in Fig. 2.

In order to form corners or angles, a portion of the marginal corrugation 1 of one pile is removed or omitted, as shown at 6 in Fig. 3, and projects between the adjacent locking member 5 and the corrugation 3 of the intersecting pile, while the other locking member is arranged with an extension 8, which extends over and locks the corrugations 1, as at 9.

The piling may be driven in sections, such as shown in Fig. 1, and after they are in the required position the cells 10 may be em tied of the material therein by means of t e sand-pump, hydraulic jet, or other device employed for this purpose, and, if necessary, the cells may be filled with concrete or other material. If, however, the mass to be penetrated is easily compressible, the corrugations 1 1 and 3 3 may be provided with shoes or jaws attached thereto and the cavity filled before or after driving, according to the requirements of the case. When it is desired to adapt this improved piling construction to the purposes of sheet-piling, the corrugations 1 1 and 3 3 may be made much smaller or more numerous for the same width of pile, or the configuration of the corrugations may be modified. For instance, the corrugations may be flattened, and the webs 2 may be bent into a curve reversed to that of the corrugations 1 1 and 3 3 after the well-known form of corrugated sheets used for roofing.

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

1. A metal-piling construction comprising corrugated plates secured together in pairs and provided with looking members attached to the said plates.

2. A metal-piling construction comprising all have the same radius, and thejlo clri'ng of i IOC corrugated plates secured together in pairs at the meeting edges of the corrugations and provided with looking members attached to the said plates.

3. A metal-piling construction comprising piles having cells, and means secured to said piles for locking them together.

4. A metal-piling construction com rising piles having cells and webs between t e said cells, means secured to said webs forlocking the piles together.

-'5. A metal-piling construction comprising piles having open spaces webs between the said open spaces and splices for securing the said piles together.

6. A metal-piling construction comprising piles having cells, the wall of one of the said cells adapted tofitinto one of the cells ofthe adjoining pile, and means for locking the 20 said pilesto ether.

7. A meta piling construction comprising piles having cells and webs between the said cells,-the walls of one of the said cells adapted to fit into one of the cells of the adj oining pile, splices fastened to thewebs of the said pile, for locking the piles together, the said splices being each composed of a fiat portion secured to the web and a curved locking member.

in testimony whereof I aflix my signature 1n presence of two witnesses.
