.To all whom it concern:

Be it known t at I, FRANK Anmour NoULm-:'r, citizen of the Uliited States, residing at New Orleans, in the arish of Orleans and State of Louisiana, ave invented new and useful Improvements in Piles and- Pile Structures, of which the following is a 4 specification. A

'My invention pertains to hydraulic engineering and more particularly to piles and superstructures sup orted thereby; and it has for one of its ob .ec.ts to provide .a strong pile constructed with a view of being readily ed in position'in a secure manner, and of withstanding'without material deterioration the conditions to which piles are "ordinarily 'subjected.

, Another object of the inventionis the provision of piles constructed with a view of being-combined and connected together and braced in order to constitute a stable support for anything that may be placed -ther'eon. J

Anotherobject is the provision in combination with a plurality of piles, of girders constructed of reinforced concrete and connected with the piles in such manner that the girders are possessed of great strength in proportion to their size.

Another bject is the provision of piles provided with appuitenances whereby they are adapted when arranged at the endof 'a wharf or dock to withstand the impact ofa landing ship, and prevent the same from injuring the wharf. Y

Other objects and advantageous characteristics of the invention will be fully understood from the following description and claims when the same are read 1n connec tion with the drawings, accompanying and forming part of this specification, in which: Figure l is a broken elevation of so much of a structure as is necessary to illustrate the'best practical embodiment of my inven tion of which I am cognizant. Fig. 2 is a transverse section illustrating the manner in which I prefer to construct the metallic socket embodied in each of the piles. Fig. 3 is a similar view illustrative of the manner in which I prefer to construct the metallic shoe comprised in each pile and adapt ed to receive and reinforce concrete or other. increased plastic material and lend stren th to the connection between the same %1e socket. Fig. i is a transverse sec tion illustrative of themanner in which the of the pile. Fig.6 is adetail vertical section showing the means on the outer pile for supmetallic stays are connected with the piles. Fig. 1s a detail diametrical sectionshowing the construction of the intermediatelportion '60 portingyapd holdin a bumper of wood or other material suita 1e to its purpose; Fig. 7 IS a transverse, section taken in the plane indicated by the line 7 -7-5015 Fig. l and showing the reinforcing means-in the concrete together with the anchor for effecting connection between '=the concrete portion of the pile and a concrete girder superposed thereon. Fig. 8 is a' detail section taken at a; right angle to'Fig. 1 vand showingthe' manner in which the. concrete-.. 'irder arranged above leach. pile is-rein orc ed be tween piles.

. Similar letters designate corresponding parts in allof the views of the drawings, referring .to which:-

Aand A are piles of which any suitable I number may be emplpyed as occasion...de-

inands. Each of the said piles comprises a lower wood portion a designed to be driven downwardly through the bottom of a bod of water or through other .earth"until-'1t 7 brings up against a hard :stratum, and havmg its upper portion b-i'educed; a metallic socket c which is preferably driven-on the reduced portion 6. of the wood-before said reduced portionis below the low water line; a metallic shoe (lpositioncd in the socket a aiidiabofl; thewood portion a, and concrete or other suitable'plastic material 6 arran ed within and extending above-the said socket.

The metallic socket a is preferably formed in the manner shown in Fig. 2that is to say, by bending a sheet of metal into tubular form, and connecting the meeting edges of the said sheet through the medium of'a coupler comprising a bar or plate g. ar ranged at the outer side of the sheet, and rivets lb headed at their outer ends and driven through the bar or plateg and the edge portions of theshcotand havin their inner ends mashed and countersunk 1n, the

inner sides of said'edge portions. Mani-' festly in this manner a strong and durable socket is produced and one possessed of the requisite stiffness and interior smoothness.

Ata'n intermediate point of its 1c the socket c is provided "with a metallic diaplllil 'lll i having its edge turned down-v and riveted to. the wallof the ward socket as best shown in Fig. 5g-the said diaphragm i being adapted when the socket c is driven on the wood portion a to bear and rest upon the upper end of the said wood portion. The metallic shoe d is preferably constructed in a reverse manner to' the socket e., of a sheet bent'-into tubular form and havin its contiguous edges conneeted through t e. medium of a bar or plate gextending-lengthwise of the shoe and within the same, and rivets It headed at their inner ends ,and extending through the Y bar 6i plate,g' and, .the edge port ons of the sheet, and having the r outer ends ably b'y adiaphrag'm j of metal connected Y to -theshoe as shown and adapted to supportthe concrete in the shoe an to bear upon the diaphragm i, Fig. 5. The concrete 6 extends from the bottom or diaphragm j 7 of the shoe d a suitable distan'ce above the upper end of theshoe, and itwill be'observed by reference to. the drawings that the said concrete is reinforced by vertical rods k, of metal, and that a metallic tie-bar Z'is' securely-anchored in-the upper ortion of the concrete and extends upwar 1y beyond the upper. end thereoffor a purpose herein.-'

after. set. forth. j ;,Itwillalso be observed in,

the drawings that at intervals of its length the concrete e 1s prov1ded,-with"metallic collars m the exterior diameter of which correspondsto that of the shoe d; that a coating of cement plaster i. 6., plastic cement'n surrounds the colierete 6 between the lower collar m and the. intermediate collar m, and also betweensaid intermediate collar m and the upper collar m; and that metallictubes p p extend diametrically through the concrete and the cementplaster,"and are designed .for the reception'of bolts r,.each of which has an eye at one end and a nut-or other" securing device at its opposite end. The sa 1d collars m serve by surrounding the concrete (1 to reinforce the same and in'thatj way lend increased strength to the, pile.

The reinforcing rods k and the tie bar-il, the metallic collars m, and the metallic tubes 7) as well as the shoe d .which is connected to the concrete bydianietrical bolts 8,

are all arranged as shown, relative to the concrete portion 6 at the time of the manu- -facture'.thcreof, and after the concrete has hardened. or set the covering ofcementplaster is applied; the said covering a being exteriorly ofa .diameter corresponding to the exterior diameters of the shoe d and collars m, so that the exterior diameter of the-reinforced concrete-portion of the pilejs uniform throughout the length of the said reinforced concrete portion. I would also here state that by preference all of the metallic elements entering into my novel pile are -preferably provided with two coats of Galterior of the concrete portion e at the time I of manufacture thereof,- is adaptedto prevent water from lodging in or working against the said indentations, with the re.- sult that the periodofusefulness of the said concrete portion 0 is materially prolonged;

-. It will be understood from the foregoing that the concrete portion e is equipped with the appurtenances mentioned at any suitable time or place, and that the said 'concrete portion and its appurtenances, in-

cluding' the metallic shoe d, are handled as a unit and arran ed as described, relative ,to the socket 0 after the said socket 0 has been driven'on the wood portion a, At this point 'I'deem it proper to say.that after the -metallic socket c is driven on the wood por tion a, a wood follower (not shown) is arranged in the upper portion of the socket c and upon the diaphragm and the blows of the pile driver a're imposed on'the said follower until the wood portion a is carried .tothe-point desired below the lowest water mark; it being desirable for the wood portion a to always be below the water in order to prolong the usefulness of the said-wood port-ion. Then after the wood portion a and cred with'Galva-num paint or its equivalent, are positioned as described, the concrete portion e equipped with the shoe d and the other appurtenances described, is arranged so that the shoe d is snugly received in the socket c,- whereupon the said shoe- (1 and socket 0 will cotiperate to .eii'ect a strong and durable connection of the concrete portion 6 with the wood portion a. After being secured in position as described, the concrete portions 6 of the two piles A and A are connected through the medium of crossed stays B, having turn-buckles C and also having D-designed to be engaged with the eyes. at the endsof the bolts r, which extend through the metallic tubes 7), as before described, the said crossed stays 'B being adapted to unite the piles in a single structure and contribute to the strength and toe the steel socket c, which socket is also covill) weight-bearing capacity (if-the structure.

The said stays B in common withthe other metallic elements ofthe structure are pref erablyfcoatd'witli Galva num paint or other preservativei'precedent to being placed in positio zn'wiu be asst-tea by reference to Fig 1 130 i that the metallic sockets c and the metallic shoes (I, as well as the wood portions a of the piles, are arranged entirely below the lowest water' mark,.s1nce said arrangement eonduces toprolonging ,the usefulness of the metallic sockets and shoes.

.In addition to the elements enumerated, each pile A comprisesimetalhc tubes 72' embedded in the concrete portion 6, and arms of'eoncrete, integral with the portion e,

' and reinforced by metallic sections F, which are embedded in the concrete portion 0 and the concrete arms or brackets 0 as shown.

.T he arms o'r'braekets e of the pile A aredesigned to support bumpers G. of wood or other suitablematerial, which bumpers are I connected to the pile by bolts II extending a through the bumpers and the tubes p.

From this it follows that piles of the A type are adapted more especially for use at the outer end ofa wharfor dock, ,the bumpers G in such lo -ation ll'tlllg adapted to receive the impact of ships and protect the wharf against injury; I would have it understoothhowever, that the use of piles of the A type is not limited to wharres or docks, inasmuch as said piles ofthe A type may obviously be fused to advantage in bridge work, trestlework and other work to which they are applicable.

In the embodimentillustrated, the upper ends of thciconcrete portions o f.the piles are let into recesses I in the under; sides of girders J, and the said girders J m turn are let into recesses K in the under sides of girders L disposed at right anglcs-to the girders J, and the tie-bars Z of the piles are extended upwardly through the girders J and intothe girders L, at. which latter point the tie-bars are suitably secured, whereby it will be manifest that the tie-bars Z will serve to strongly connect the girders -togethcr and to the piles. The girders are preferably formed of concrete or othe'r plastic material, and each is provided with a metallic reinforcement M embedded therein,

and made up of plates t disposed in vertical alinement with the piles and receiving the tic-bars l, and spans extending between the said plates't and respectively made up of lower straight bars wv and upper curvilinear bars 4). By virtue of the. said spans it will be readily observed that the eight-bearing capacity of the portions of the girders between supports is 'materially increased.

Upon-the girders any desired structure may be superposed. but I have deemed it unnecessary to illustrate such structure, inasmuch as it forms no part of my lnvcnlion.'

As before stated, the construction herein illustrated and described constitutes the best practical embodiment of my' invention of which I am aware, but it is obvions'that in the future practice of the invention such changes or modifications may be made as;

do not involve departure from the scope or my lnvent on as defined in my appended claims. Y
