Yobject of thisinvention; is tofprovide a piling which may be sunlrnoiselesslygand ywithout vibration, andy which is consequently able less force thanis requiredtojdrive the ordinary piling. n Another object is to provide a piling which mayl be -'conveniently made up in relatively `short,`standard size Asections for convenient transportation and the sections readily coupled together as the.V piling is screwed into the ground. Another object is to provide a pilinv which may be conveniently sunk in water-V caring sand or other'very moist soil withoutthe need for well-pointsor other moisture extractin'gapparatus. Y

Figi is a broken viewfpartlyinside eleva.- tionand-partly in longitudinal section showl described and printedy out y threaded internal coupling members 11. f
l sections.
The pilingshellis built up of a. plurality of generally similar connected hollow metallic sections. These .Sections kmay be ofi'olled, pressed, or cast metal of sufficient thickness and strength so that they can be screwed into thek round without interior reinforcements.
, Pre erably the sections are of` similar threaded coniiguration both interioi'ly and ei;- te'riorly. The threading may assume many forms buty I prefer to use the buttress threadving illustrated in order to insure maximum fractional resistance toa direct downward thrust. It is well known, of course, that the load sustaining 'ability of piling is for the most part directl f determined by its frictional resistance against. a downward thrust.
' The standard length threaded shelly sections designated byrefeience numerals 10, 10 are'preferably coupledtogetlier by similarly Preferably the abutment lines of adjacent shell sectionsl do not follow the line of the threads but are transverse to the longitudinal axis *of* the piling. lIn coupling two of the piling sections, the coupling piece 11jis partially screwed intoy the ytop of "a previously siinksection V10 yand a superjacent section 1() isA screwed onto the upwardly projecting end of thecoupling piece until lit abuts the subjacent section 10. y
Iny order'torender the shell waterproof, packing rings 12 may be proifided between theabutting ends of adjacent shell sections and such abutting ends are preferably beveled Vas shownin 13 of Fig.y 5 to insure a better compressive'acti'on on the'packing rings.
Preferably all of the sectionsV 10 are of uniform diameter except that the lowermost entering section 10a tapers toward the bottom where it may terminate in a piercing pointer a cutting point. T he latter being illustrated in the present case and is provided with openings 14 so that the soil which is cut away may pass 'into the interior of the sl'iell.
Numerous expedients might be resorted to for sinking the piling and ii'npartingv the necessary rotary motion to the uppermost section ,thereof to'efecft the screwing action.
I have yshowny quitediagrammatically one form` of sinking mechanism which includes asocketmember 15, this socket memberbeing hollowthroughout its length and Vat its lower end shaped to receive the upper end is a' broken longitudinal sectional of one of the sections 10. The socket member is preferably keyed to a worm gear 16, housed within a gear casing 17 and driven from a screw 18. A suitable thrust bearing' 19 is provided between the gear 16 and the bottom of the casing 17 and the upper end of the socket member 15 may be outwardly flanged as at 20, whereby an additional thrust bearing 21 may be disposed between the flange and the sleevelike upward extension 22 of the casing. The hoisting apparatus, such as the cables 23, may be conveniently attached to the casing 17. It
will of course be understoodthat the screw 18 ris driven in any suitable manner to rotate ,the .gearand socket and that the sinking of the pile 'sassisted by the weight of the operatingmechanism which rests upon it. After one'shell section has been substantially sunk,
lect in the lower end of the shell, out through the top'thereof. f
After the sectional shell has been completely assembled, and sunk as shown in Fig. 2, and the soil, ifr any, removed from the bottom thereof, the shell serves as a moulding form for poured'concrete f 21, and thereby determines the exterior configuration Vofthe metal encasedconcrete pile. f
The use of the shell to determine the exterior shape ofthe 'concrete fis an important feature, since the corrosion of the shell after a long period of use cannot materially affect the efficiency of the piling. As the shell rusts out, the concrete itself presents ya threaded vouter surface to the soil. f
' It is believed that the method of sinking the piling will be kfully understood from the fore oing general description of the pilin itsel ,f and its sinking mechanism.` Suc method briefly consists of screwing yinto the grounda sectional metal shell, the interior configuration of which predetermines the shape of a subsequently cast concrete filler and then pouring concrete/into the hollow shell until the latter is completely filled.
Where the piling has a cutting point, the method'jadditionally includes the step of blowing or otherwise 'removing soil fromthe interior of the shell through the open 'upper 'end thereof, either dui-ing' or subsequent to' the sinking operationand the step of coupling additional sections to the top of the 'piling duringy the courseof the sinkage.
'Obviously various changes and alterations v'might be made both in the pilingand the method of sinking it,without departing from the spirit and scope of the appended claims. l Having thus described my invention, what ,I claim as new rand desire toA secure by Letters Patent is as follows: Y l.
