Etlti'l'fiil. SHEET PlLENGE No. s55,oso.

To all whmn it may concern.

Be it known that'l, JULIUs R. VVEMLINGER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented. certain new and useful Improvements in Metal Slieet-liling, of which the following a specification.

In the manufacture oi metal sheet piling one has long sought .to design section or unit, which could he rolled or pressed into its final shape as an integrity, in order to avoid the riveting which is required where the units are made of a number of parts nmnufactured separately, and which, outside of other disadvantages and drawbacks, is a considerable item of expense, so that its elimination means economy to the manufacturer as well. as to the consumer.

The sections designed heretofore to be rolled, are extremely diflicult, or even inipossihle, to he rolled commercially, and it the OlJjEOl; of this invention to provide a unit which maybe rolled easily and economically,

and will not require riveting of any kind- Referring now to the drawing, in which like reference numerals refer to like parts in the various figures, Figure. 1 is a transverse section of the new unit, Fig. 2 a transverse section of several units locked together and shown ona somewhat smaller scale than that of Fig. 1, and Fig. 3an elevation of a portion of the units shown in "Fig. 2.

Each. of the units'nf my improved sheet piling comprises a web 1, sides 2 having reinforced edges 3, and locking flanges 4 projecting from the web 1, the whole unit being one integral piece. The sides 2 are preferably inclined with respect to the web 1, as shown, and they are preferably provided with reinforced edges of bulb-shape, although these particulars may be modified, as, circum stances require. The locking. flanges 4 of each unit are so arranged as to provide Specification of Letters Patent.

As shown in. Figs. 1 and 2, the web 1 is than the sides 2. This difference in thickness should be such that, whenthe units are in position, as shown in Fig. 2, the combined. thickness of the contiguous sides 2 of two units is, approximately, equal to the thickness of the web 1 of each single unit. This is an important feature of my invention, as thereby a sheet piling is 0btained,-which is of practically uniform thickness and strength, whereby a most economical and effective distribution of material is provided.

it follows that an excess of material would be" present at the joints, stood.

The sides 2 are enlarged at the edges, as at as will be readily under- 5, not merely for the purpose of providing means cooperating with the locking flanges 4 to secure the' units together, but also for the purpose ofreinforcing the edges ofthe units themselves, for in shipping and otherwise handling the units the edges are naturally liable to be injured more than the other por tions of the unit by reason of, being exposed, and, furthermore, the edges are likewise more liable to injury when the units are driven, because they are the first to suffer when the unit strikes an obstruction. I the reinforced edges 3 serve a doublyl valuable purpose from the consumers stdnd oint, while from the manufacturers stan point they are advantageous in other; which will be referred to in a subsequent a plieation covering the process of rplling t e units.

It will he noted that the position of the looking flanges 4 is such that they are well Therefore,

W at I claim as my invention and desire to secure by Letters Patent is 1. In metal sheet piling, a unit comprising aweb, sides at an angle thereto, the said web being-thicker than the said sides, and locking flanges integral with the said web.

2. In inetal sheet piling, a unit comprising a web, sides at an angle thereto, the said web being thicker than the said sides, locking flanges integral with said web, and enlarge 'ments at the edges of the said sides.

3. In metal sheet piling, the combination 'of units each having a web, sides at an angle thereto having re-inforced edges, the said web being thicker than the said sides, and means integral with the said web for locking contiguous units together.

4:. In metal sheet piling the combination of units each. havin a web, sides at an angle thereto having rein orced edges, the said web being thicker than the said sides, andqloeking.

5. In metal sheet piling, the combination of units having heavier and lighter portions,

.the latter being at an angle to the former,

and being provided with enlarged edges, the units being so arranged that the lighter ortions of contiguous units overlap each 0t ier, and means for locking contiguous units together.

6; In metal sheet piling the combination of units each com rising a heavy portion, lighter portions at t e sides thereof and at an angle thereto, and means for securing the said units together at their edges.

7. In metal sheet piling the combination of units each comprising a heavy portion, lighter portions at the sides thereof and at an angle thereto, the said lighter portions being approximately half the thickness of the said heavy portion, and means for securing the said units together at their edges.
