Specification of Letters Patent.

Patented April 23, 1907.

Application filed August 16, 1906. Serial No. 330,823.

.To @ZZ whom, it may concern:

Be it known that I, JESSE THEODOR PYLE, a citizen of the United States, and a resident of Amarillo, in the county of Potter an... State of Texas, have invented a new and Improved Pile Structure, of vwhich the following is a full, clear, and exact description.

This invention relates to certain improvements in structure formed of sheet piling driven into sand or soft earth and having the enclosed material removed, whereby the pile may be filled with concrete to serve as a foundation for bridges, buildings and the like. The walls of the structure are made up of a large number 'of sections which are driven into the sand or soft earth one at a time and each succeeding one u on being driven becomes locked tothe one ast inserted It is particularly old to employ separable secI tions of this kind in the construction of piers, and it is further old to form these Sections in a large circle or ring and excavate the material from inside the said enclosure, but a if not inoperative, where it is desired to drive piling to a considerable depth, as a single row 1s not sufficient to withstand the enormouspressure upon the outside after the enclosed material is removed and before the concrete is inserted. i

By the use of my improved sections, piles may be driven to any depth desired and there is no liability of the piles caving in beforel the concrete is packed in lace.

Reference is to be ad to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures,

fl ure 1 is a diagrammatical plan of brid e pile showing the arrangement of sections; Fig. 2 is a side elevation the; eof; Fig. 3 is a horizontal section of one of theT-shaped sf'ctions employed; Fig. 4 is a horizontal section of another form; Fig. 5 illustrates one form of the extensible web; Fig. 6 illustrates a second form of the extensible web, and also the means for holding the jet tube in the first section inserted; and Fig. 7 is a side elevation of the form shown in Fig. 6.

The simplest form of section which I employ, comprises a tube 1 having a slot 2, ex-

tending along one side throughout its entire length, and having a web 3, extending from the tube along its entire length on the side opposite to the slot. At the end of the web is a head 4, whose Snape in cross section is substantially a sector of a circle, and adapted to fit the inside of the tube of the next adj acent section, while a flange adjacent the head passes through the Slot of this section.

On the web 3 and adjacent the head 4 are two fianges 5 which may be integral with the web or of separate pieces rigidly secured thereto, which anges extend in the arc of a circle and spaced from the surface of the head at a distance slightly greater than the thickness of the Wall of the adjacent tube. '.lliese flanges fit the outer wall of the tube adjacent the slot therein and serve to prevent the web of one section from extending more than the desired distance into thc slot of the tube on the next adj scent section. These sections are driven into the sand one atatime, and as i each one is driven a jet tube 6 is inserted into the tube 1 of the section and the material within the Gube is either forced or pumpedv out of said tube. It will be noted that after the irst tube is inserted, the slot in the second'will be closed by the head 4 of the first while the second is being inserted and the material may be easily removed from the tube cof said second and each succeeding section, but at the time the first section is driven, it is necessary to provide certain means for closing the slot to prevent sand from coming into the tube as fast as it is removed by the jet tube 6.

In Figs. 6 and 7, I have shown a jet tube 6, having a plurality of bands 7 surrounding the same, and each band attached to a short web 8, having fianges 9 fitting the outer surface of the tube. AS the first section is driven into the sand it carries the jet tube with its bands 7 and slot-closing means 8 and 9, so that the sand may be removed from the section and other Sand prevented from entering the slot. After the first section is inserted, this particular means is no longer necessary in connection with the other sections and a simple jet tube is freely inserted Within the tube of the second and each succeeding section to remove the material therefrom. As soon as one section is driven and the material removed from the tube, the latter is filled with concrete to strengthen and rigidly hold the IOS -same in place. These sections are usually driven in the arc of a circle and as the last section is about to be inserted it is often found that the distance between the sections on the 5 opposite sides of the remaining gap is greater or less than the normal wid-th of a section, and to accommodate for this, I provide certain sections having extensible webs, Whereby the distance between the tube and the ro head of said section may be made greater or less to exactly fill the space between the ad- `acent sections. This may be accomplished y making -a section of two separate parts and. secured together the overlapping pori 5 tions-of the web by rivets l-passing through slots inl the overlapping portions, as illustrated inv Fig. 5, or one portion of the section may have two adjacent web members between Which a web member of the other porzo tion of the section is adapted to slide, the

three members being held together by rivetspassing through slots as in the form above described.

The modiiication of the extensible web is z 5 clearly illustrated in Figs. and 7.

A single ring of these sections is entirely inadequate and even dangerous. -When it is desired4 to sink a pile to any considerable depth and to strengthen the pile, I preferably 3o drive sections to form two concentric rings 11 and 12,-as shown in Fig. 1, said rings being spaced. and Vheld rigid by radial partitions 13. Both of the rings, and also the partitions are made-up of the unit sections above described, but in order to secure the partitions 13 to the concentric rings 11 and 12, I provide a form of section shown in Fig. 3, in which the web 3 has a branch web 14 rigidly secured at an angle thereto, whereby the tube 15 is drivensi- 4o .multaneously with the tube 1 and junction bet-Ween two rows of sections at an angle witheach other is thereby perfected.

In certain forms of piers it is sometimes desirable to have two rows of sections intersecting each other, as shown at 16 in Fig. 1, and I provide the form of section shown in Fig. 4 to be usedI in cases of this kind. This form of section has two branch webs 14 attached to the main web 3, and one of said 5o branchwebs 14 has a tube 15, as in Fig. 3, while-the other branch web carries a head 4, said head and tube being at substantially the same distance apart' as are the head and tube of the normal unit section.

In driving the sections to form a pier of the sha e shown in Fig. 1, the material is excavatedJ from eachof the enclosed spaces 17 as soon as the walls forming one of said spaces are completed and the space illed 6o With'concrete. -The space within the-inner ring of sections is likewise excavated and filled with concrete, so that -the completed pier is-'a solid mass of concrete having the sections embedded therein, said section having been employed merely as a Colfer-dam to hold the surrounding material in place while the concrete pier was being iilled out.

It is evident that the improved form of sections above described may be employed for placing the concrete foundations in sand at any de th, and is particularly useful Iwhere quic sand is encountered. The sections may be employed either for placing c oncrete piers, bridges, or foundations of buildings, or for anyother similar purpose. For

cofer-dam work the sections are employed as in the building of concrete 'piers but the spaces 17, enclosed by thesections, are not filled with concrete, and the row of sections surrounds theplace where it is desired to place any suitable structure on the river or ake bed, and when said structure is perfected, the sections may be removed without the same having been injured in any Way, and said sections may be again employed foi' similar work.

^ Having thus described my invention, I
