METAL SHEET PILING. APPLICATION FILED MAR.7,1908.

Patented May 25, 1909.

jivenlvr IEETAL SHEET-FILE? Application filed lrl-iarch 7, 1908.

To all whom it may concern:

Be it known that I, Trier-airs t3. Jamison, a citizen of the United States, and a resident of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Metal Sheet-Piling; and I do hereby declare that the following is a full, clear, and exact (ilesci-iption there-cf, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in metal sheet piling adapted for the construction of the walls of cofi'er-dams and like uses Where it is desired to arrange for a watertight oint between the units of the wall, and the invention refers more specifically to means for providing a water tight joint between the units of the piling wall.

My improvements are intended to PI'OVlClG a water tight joint between units of a piling wall composed of a single row of such units, thereby avoiding the necessity of providing a double wall and filling the s ace between the same.

A further object of the invention is to provide a water tight connection between metal sheet piling units wherein said units and the parts which form the water tight connections may be made of simple commercial rolled shapes.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

As shown in the drawings :Figure 1 is a top plan view of a short section of wall made of metal sheet piling embodying my invention. Fig. 2 is a perspective view of the upper ends of a plurality of pile units. Fig. 3 is a fragmentary perspective view of one of the units. Fig. 1 is a plan view showing a modification of the joint between the units.

As shown in the drawings, 10, 10 designate the sections or units of the sheet piling, which comprise fiat web portions and marginal flanges,the latter fitting in suitable interlocking relation to each other, whereby each unit, as driven, is guided into place from an already driven unit, and said units are held permanently in position one with respect to the other. The form of unit herein shown is that of an Lbeam and one of the features of my invention is to employ a commercial rolled shape in the production of the piling.

iipeeification of Letters Patent.

Serial No. 419,622.

The flanges 11, 11 of said I-beani units are shown as arranged parallel witn each other, but not in contact at their adjacent faces, and the dm ices for producing water tight joints be en the units are located in the spaces v. ch separate the flat faces of said flanges. the said units are adapted for interlocking and sliding connection with each other bymcans providing for the guiding of each unit being driven from a unit already driven, and which will also hold the sections or units rigid together when driven. The de vices herein shown for locking the units to gether comprise clips 12, 12 which are made k .neraliy like the locking c l s shown in the prior U. S. patent to Cluxton, No. 878,773, granted l ebruary 11, 1908. Said ciips comprise shank portions I3, 13 which are bolted or otherwise fixed to the webs of the units, and hook portions 1 1, 1a which fit in contact with the flanges of the units to which they are attached and extend beyond the same for interlocking engagement with the flanges of adjacent units. The only modification of the clip herein shown from that shown in said Clunton patent, lies in the fact that the hooked portions I l are made slightly longer to eX- tend across the space which separates the flanges 11 of the units that are locked together by said clips.

Referring now to the features of construction which constitute the principal part of my invention, the same are made as follows: 16, 17 designate channel bars which are fixed to the flat outer faces of the flanges 11 of the I-beam units, said channel bars being arranged with their web portions 18 parallel with said flanges and with their flanges di rected outwardly at right angles thereto. They are fixed to the units by rivets 20, or like fastening means. One of said channel bars, the channel bar 16 as herein shown, is made wider than the other channel bar 17 and is adapted to receive the latter in close fitting engagement, as clearly shown in Figs. 1 and 2, said flanges overlapping each other throughout the principal portions of their width. Said channel bars 16 and 17 inclose, when fitted together between two driven sections, a space which is adapted to be filled by any suitable packing material 2]., preferably of a nature which may be placed in said space when in a plastic condition, and may be afterward tamped therein and allowed to harden. Concrete and like cementitious material or softened dirt may be employed. Desirably the material is such as to expand or swell in the presence of water, thus insuring a joint which shall be maintained tight. A material which is poured into said packing spaces when in a soft or plastic form is preferable inasmuch as it entirely fllls said spaces and tends to close the spaces between the overlapping flanges 19 of the channel bars, if such flanges be separated. It will be observed, 'by in spection of Figs. 1 and 2, that water, in order to find its way from one side of the wall to the other, must pass between the overlapping flanges 19 at one side of the piling wall, through the body of the packing material 21 and between the overlapping flanges 19 at the other side of the wall. It will be observed that the packing between adjacent units is formed by overlapping flanges extending at an angle to the adjacent flat faces of the sections or units and fitting in contact with each other and inclosing between the same spaces to receive packing material. Thus, it will be obvious that, with said parts fitting closely together, and the spaces surrounded by said channel bars filled with a packing material which expands in the presence of water, an extremely effective joint will be provided to prevent the passage of water between the units.

In Fig. 4 l have shown a n'iodification wherein a single channel bar 22 is employed between the flanges of adjacent units, the said bar being attached to the flat face of one of two adjacent flanges, and the flanges of said channel bars engaging at their free longitudinal margins the other or opposing flat face of the adjacent flange. in this construction the units are fastened together by the clips 12 shown in the previously described construction.

I claim as my invention 1. Metal sheet piling comprising interlocked units formed with marginal flanges which are separated by a space and bars attached to said units having parts which extend across the space separating the units, the said parts of the bars being arranged for overlapping contact at their free margins and throughout substantial portions of their width whereby is formed elongated spaces inclosed by the bars and units to receive and retain a packing material.

2. Metal sheet piling comprising interlocked units formed with marginal flanges which are separated a distance from each other, and flanged bars fitted to the flat faces of the unit flanges and overlapping each other at their free margins and arranged to inclose spaces to receive a packing material.

3. Metal sheet piling comprising interlocked units formed with marginal flanges which are separated a distance from each other, and channel bars fixed to the opposing faces of said flanges and arranged with their flanges in overlapping relation.

1. Metal sheet piling comprising interlocked sections embracing I-beams, the flanges of which are arranged parallel with and separated from each other, and channel bars attached to the opposing faces of said flanges and arranged with their flanges in overlapping relation to form spaces to receive a packing material.

In testimony, that I claim the foregoing as my invention I aflix my signature in the presence of two witnesses, this 29th day'of February A. D. 1908.
