Abstract: 387,867. Piles. RAYMOND CONCRETE PILE CO., 140, Cedar Street, New York, U.S.A. April 2, 1932, No. 9498. Convention date, April 28, 1931. [Class 68 (ii).] In making a concrete pile by filling a preparatory shell, the shell is made in sections of thin metal, each larger in diameter than the one below it, and each adapted to surround one of the cylindrical steps of a core by means of which it is drawn into the ground. Fig. 3 shows a drive 20 with an annular shoulder 22 and a downwardly extending tubular stem 24 ; the shoulder rests on a core section 27, the uppermost of a series of core sections of decreasing diameter. The section 27 has a lining 28, and the stem 24 is secured by dogs 30 pressed out by flat springs 32 and withdrawable by a cord 38 ; each section, such as 27, is similarly secured to and released from the section next below it, thus forming a long core, which carries down into the ground a hollow shell to be filled with concrete when the core has been removed. This shell also is made in sections, each of which surrounds a corresponding section of the core. To enable the shell sections to be made as light as possible, they are designed so that they may be drawn into the ground by the core, and they are corrugated to withstand the earth pressure after the withdrawal of the core. To reduce the wear and tear, each section is provided with a " plough " ring 56, Fig. 6, set under a shoulder 46. The shells 50, 54 are connected by a coupling 52, the corrugations being of screw form. In modifications, the sections are spot-welded to a connecting bush, and the material of the rings 56 is of L- or Z-section, or circular, or the part 46 is reinforced by concrete.
