Y, A-further object of thev inventionfis to provide a new and efficient `process of constructing pilings Vwherebyrthel said pilings 'may be s et'in place and constructed with a minimum offexpense.`

" VIn theI drawings which form a partlof application, Fig. 1 is a transverse'sectionaly View showing the piling'socket after having Y been drilled with the drill pipe'and 'baglining inserted within the same; and

Y Fig. Zis-a trasverse 4sectiona'ly'view showing themethcd of constructing thehplling` when the ground tobe worlredm isvsub-l4 merged below water.

LikeV characters of. reference arefused throughout the following f's'pecication Vand i' the accompanying drawinlgs todesignatecorg Vresponding'parts.-

- The process of-constructinga piling to be embedded in land not coveredwith water" will bel vfirstV described] The drill pipe 1 having Vthe usual form of cutter will be used to bore the piling socket 2 to the desired vdepth, and thebase of the said socket may Vbe enlarged as at 3 to provide for aV suitable footing for the piling when in position.

It is customary when-theV holes for the pilings. are drilled gto placea casinlgabout the interior thereof to `prevent the .walls of the holes 'from caving Qin. .One of `the, main features of'my inventionis to dispense with 'the use of these casings and `in lieuv thereof to fill thev socketV or hole 2 with soft mud for Y clay as the hole is being drilled.v The opening orl socket beingentirely filled'with the soft, mud or clay lpositively prevents any caving in of the walls.

When the desired depth for the opening is reached,'the drill pipe V1 is withdrawn therefrom and a closely wovencanvas bagv or lining 4 is drawn over the said drill pipe as illustrated in Fig. 1 of the drawings. A

` plug 5 is secured to the lower endof the canvasbag or lining 4 in any suitable man# ner;lthen it is inserted within the openV end canvas lining are forced down through the .Geenen Alinnssngkonivnw oRLnANs,cnonistarmi.`fk 'p mud or lclayffin: the; .2

The l forced down through the mud, after which the concrete is poured or pumped therethrough until the hole is completelysilled'.l

The Walls of the. casing 'Z prosride a mould or casing `for the portion of the piling eX*- :tending from the surface of the land to the` f upper end of the said piling. lAfter the concrete has firmly set, the hooks 11 may be` engaged by'any suitable means and the locls ingfpin 1'0 Withdrawn so that the casing 7 may be opened and'l readily Withdrawn.

From the foregoing description it will be apparentthat my process of forming pilings vWill enti-rely do 'away with the necessity of inserting the. usual bracing casing in the holes to prevent caving 1n` of the same 'as they are drilled', whicht feature alone makes a. greatsaving ineXpense in thev construction of" the pilings.

minor changes in detailI of construction may ybe *resortedVv to Without' departure from the spiritV of the invention.

2. 4The process of forming concrete pil-A Vings in land submerged under Water consisting of lowering. a split; casing through said Water and forcing it into thesground therebelow, drilling a hole in said ground,

iilling said hole with soft' `mud or clay as the hole is being' drilled, inserting a drill pipe surrounded by a canvas bag or lining through ,said mudV to a point adjacent the lower end of said hole, and `forcing. concrete through said pipe into said bag, and retracting saidY pipe from said hole als the height of the concrete increases.v

4t. The method" of constructing a concrete piling consisting of digging a hole and at the same time filling the hole Withy viscous substance, placing a lining bagover a pipe, inserting a plug carried by'said bag into the Vlower end of said pipe, insertingl said bag andE pipe through the Viscous substance into Vsaid hole, said viscousV substance tending to press the bagagainst the pipe, pumping or pouring concrete through said pipe-so that said plug will Ybe forced' from thefbottom pipe, fillingthe bag from theV bottom upl Wardly with concrete, the confined' airwithin the pipe servingto spreadv the bottoni of the bag Aas the concrete is receivedv Within the 'same so that the bag ,Will be spread away Vfram the pipe'and' contact with the Wall ot said'hol'e as thebag continues to be lled.
