Patented lian. 3, 1933 UNITED STATES PATENT oFFlcE ELIHU D. WATT, OF LA. GRANGE, ILLINOIS, ASSIGNOR TO RAYMOND CONCRETE PILE COMPANY, OF NEW' YORK, N. Y., A CORPORATION OF NEW' JERSEY INTERNALLY TAPERED PILE SHELL SECTION Original application led August 12, 1930, Serial No. 474,744. Divided and this application filed September This invention pertains to concrete piles, with particular reference to a thin concrete shell suitable for sinking into the ground to be filled with concret-e to form a monolithic pile structure. This application is a division of my application Serial No. 474,744, iiled August 12th, 1930, entitled Apparatus for driving internally tapered pile shell sections.
The present invention contemplates the formation of a cylindrical (non-taper) pile. Heretofore it has been customary to drive shells for such piles by hammer blows applied to the top of the shell. This required the shell to be of considerable thickness in order to withstand the strains of driving, particularly the crushing strains where the end of shell sections contact with each other.
In order to save transportation and handling costs, it is desirable to make the shells as thin as possib-le. The principal object of the present invention is to disclose a thin concrete shell suitable for driving in such a manner as to avoid the above mentioned compressive stresses. In practicing the present invention I arrange on a collapsible driving core a stack of similar concrete shell sections, each section being slightly tapered on its outer surface and made quite tapered or conical on its inner surface by the insertion of a concrete lining` gradually increasing in the thickness of its walls from top 'to bottom. The driving core is provided along its length with a plurality of tapered surfaces each of which is adapted to accommodate and conform to the inner surface of a shell section. The core is driven from the top and each shell section is driven individually by the tapered core section with which it is in contact.
Further and other objects and advantages will be apparent from the specification and claims, and from the drawings which illustrate what is now considered the preferred embodiment of the invention.

sections after driving and before filling With concrete.
Fig. fl shows the stack of shell sections on Jthe expanded core, preparatory to driving.
Fig. 5 is a cross-section of a portion of a finished pile.
Fig. 6 is an enlarged view, mostly incross section, showing core and shell.
Fig. 7 is a view on the line 7 7 of Fig. 6.
The design of the shell section comprising to the bottom thereof, and the upper end of each casing 10 projects above the concrete lining so as to receive and overlap the lower end of the section above it when in assembled relationship, as shown in Figs. 3,4, 5 and 6. 'The driving core is of the collapsible type having three leaves 16, which may be moved outwardly or inwardly by toggles 18 connected to vertical axial shaft or rod 2O adapted for operation in well known manner by mechanism within driving head 22.
The surfaces of leaves 16 are so shaped that when they are assembled to form the core, they provide a series of tapered or conical surfaces, each adapted to engage a shell section of the kind shown in Fig. 2. The core is shown in Fig. l without shells, and in Figs. et and 6 with shells. in the last named gures the core is expanded to engage a stack of shell sections, each section being engaged by a conical section of the core. Fig. 4 shows the assembly ready for driving, a shoe 24 being provided on the lower end with a casing 26 overlapping the lowest shell section.
t will be appreciated that when theI assembly in Fig. 4L is driven by blows or pressure applied to head 22 the driving effect will be transmitted from the core to each shell section individually on account of their tapered interrelationship, and it will not be necessary 2 ,Y n 1,893,010k
to transmit force vertically from shell section to shell section. i
After the driving operation is finished the core is collapsed and withdrawn, leaving a 5 hollow shell inthe ground as in Fig. 3.l This shell is then filled with plastic concrete 28 as indicated in Fig. 5 to form with the shell sections a monolithic pile structure. Any spaces such as 30 (Fig. 3) between sections are filled by the plastic vconcrete as v shown in Fig. 5.
It isto be understood that the invention is not limited'totlie specific embodiment here-V in illustrated and described, butmay be usedy in other ways without departure from its spiritz as deiined by the following claims.
I claim: l l 1. A .pile shell comprising a slightly tapered annular body of thin material and a '20 lining fitted to the inner surface of the shell,
said lining having its walls gradually/increasing in thickness from the upper to the lower end thereof. f Q2.
