To all wiwm it mdy concern.

Be it known that 130mm) Cunnono Conn LING,'?3 citizen of the United States, residing at Bufialo, ill-the countyF-oi' Eric and State of News York, havcinvcntcdncw and useful lm royeincnts in ProtectcdPilih of which.

the following is a specification.

My present invention relates to the well known protcctcd iling for permnnczdwvork,

having an inter coking ste'cl shc't piling core covered and protected by s pc rmonent concrete facing, and consists of a, plirticulsr means, adopted topsrticulnr forms of piling, for binding such concrete facing to the steel. Hcretofore by Patent No. 969,343 issued September o, 1910, l have broadly protected such piling and the concrete bindin moans com risin an suitable ro'ections on the scction webs, and consisting dcsircbly of rods connected to the sections by any suitable means. Since the time of said potent I have invented an improved form of steel sheet piling, calledthcarchsd-web pil ing,whereby the modulus and moment of resistance of the section are greatly increased. In a. broad sense, protecting concrctc may be secured on'erched sections by tho some means as that of'sliid patent, but the particular form of bindin moans thero illustrated, that is integral r1 s, could not conveniently be used with the crchcd shape. I hove therefore devised for arched piling the spccislformfof binding projections here shown and described. Tnis form consists of tiomds, or wires, similar to those; of my said potent, but these are held in position by tic-bars, structurally difiercnt from said integral ribs, but functionally similan.

invention is illustrated in the drawing herewith in connection with various forms 01: pile sections.

The reference numerals of this description indicate the same parts in all the figures.

Figures 1 and 2 are cross-sections showing minvention applied respectively to two assem led arched sections and to a single larger section. Fig. 3 is a longitudinal section. Figs. dn'nd 5 show my invention cpplicd to sti'eight web Lackcwanna sections; Fig. 6, to a U. S. section, made in arched form. Fig. 7 shows a modification for binding the concrete to one side only of the steel section. l

Referring first to Figs. 1, 2 and 3, A indichte's the steel sections, or cores, of Lackewennc type having on the edges the inter locking members 2 and 3, sometimes called the thumb and finger. l is the protecting covering, or coating, of concrete, which may be applied by any desirable means, but must be securely locked to-thc steel core. Such locking, or binding, moons here consists of tic-rods, or hccvy wires, 9, arrangodsuo stontially as shown and connected to the steel cores b means of tie-bars 10, arranged to extend is rough holes 11, in the section web 12 and, engaged on each side by the tie- ;rods. These tic-hers correspond to the horn continuous ribs specified in my said patent.

When the concrctc is to be applied, the pile is inserted in a. wooden form with removable top and bottom, the tie-bars are set in place from the open top of the form and the tierods inserted on the upper side, through the hole in the end of each tie-bar. The ends ofthe rods are bent inwardly to engage with the steel core, thus giving a spring hold, and said tie-bars and tie-rods are thus held in position whilethc concrete is bein applied on the upper face of the pile. f course in this securing means there must be two tie-rods, one on each side, for each tic-bar, forthe two oppose each other tohold the tie-bar in place. Therefore, ofter the rods and the concrete are in position on one side the form and the inclosed pile are turned over and the same process reposted on the other sid of the pile, which is now uppermost. As the tic-rods are resilicnt, they adjust themselves and the tiehar to slight variations in arrangement and form of: the parts. When the concrete is applied in the form, the tie-rods end tie-bars are embedded thcrcin...nnd held against movement in an direction, and they react securely to bin the concrete to the steel. As shown in Fig. 3, these tie-bars may be of various lengths for instance shortened, and the tie-rods correspondingly formed, toward the lower end so that the concnetc may be S. type, that is hell or 1.1 0

my invention is particularly designed for use with arched sections yet it may be applied to the various ordinary forms of straight piling as shown in Figs. 4; and 5.

Almost universally, ,the concrete willbe applied to both sides, but there may be situations Where it is desirable to protect one side only, and to that end the structure may be slightly modified as shown in Fig. '1, where there is atie-rod on one side only, and the tie-bar is provided with a bent end to maintain it in place.

Having described my invention, I claim--- 1. A. protected sheet piling sectlon comprising a steel core having a web and interlocking members on the web edges, said web being formed with a series of holes, tie-bars extending through said holes and having perforated ends, and tie-rods arranged to extend through said perforations and having their ends engaging with the steel core.

2. A protected piling section consisting .of at least one steel core-section and of concrete applied to the surface of the core, said core being provided with interlocking mcm-.

core having interlocking members on both I edges extending beyond the concrete and a series of holes along. the center of its web '2 imam to receive tie-bars, extending on both sides of the web at unequal distances, said bars having end holes for tie-rods; which are bent in to engage with the core on both and 1 to exert a resilienttension to counteract each other.

5. A steel core for protected piling, tie bars adjustably extending through openins in the steel core, and binding rods ext-ent ling through holes in the bars and having their ends turned inwardly to engage with the said core.

6-. A stee'l sheet piling core for protected piling formed with o )enings longitudinally arranged in its we tie-bars extending through said openings and tree .'to move.

therein, resilient tie-rods extending through holes adjacent the ends of the bars and having their ends bent inwardly to engage with the surface of the core.

7. A protected piling section comprising 1 a steel core provided with a web and interlocking elements on the web edges, said web being formedffrom end to end'with openings arranged at intervals, 21 tie-bar arranged to extend through each opening and project. on opposite sicesof the Web, .said tie-bars adjacent the lower end of the core gradually diminishing in length, tic-rods inserted through holes in the ends of the bars, and'concrete applied to the surfaces of the core, the concrete being beveled toward. the lower end and the extreme lower end-oi? 1311 steel being left uncovered.
