all whom may concern:

it known that l, Joenrn Beans, a citizen of the United States, residing at Pocatelio, in the county of Bannock, State of ldaho, have discovered new and useful 1mprovements in Processes for Sinking Reinforced of hydraulic jets whereby water at high till pressure is forced through the hollow center of the pile for the purpose or washing away the sand or other formation below the bottom end. in the use of such methods the striking of shale or hard pan presents an in suirnountable obstacle to further progress while by the use of my process such difiiculties are overcome and concrete piles can be rapidly and inexpensively sunk not only in ordinary formations such as quiclrsand and where wooden piles cannot now be sunk to tie required depth but also in. shale and other hard formations where it is now impossible to sink concrete piles.

Instead of depending upon processes now in use I employ theprinciple of rapid rotary action of the pile, to the bottom 0t which is aifixed a cutter head or hit. Hydraulic pressure is also employed for the purpose of forcing water through the hollow body of the pile and through a nozzle which distributes the water over and around the cutter head or hit. The water is also forced through apertures extending upwardly and placed at intervals in the walls or" the pile, the purpose being to lubricate and soften the material through which the pile is being forced and to force upwardly and out of the hole made by the cutter head or hit which extends beyond the body of the pile.

One way of carrying out the invention is shown in the accompanying drawing, in which Figure l is a longitudinal sectional View. and,

Fig. 2 is a section on line 2-2 of Fig. 1.

ln these views, the pile is shown at 1, and this pile is formed with tile central bore 2, which passes longitudinally therethrough. The pile is also formed. with the tapering ports 3, which extend upwardly from the bore to the outer sides of the pile. These ports are arranged at intervals throughout the length of the pile. A bit or cutter head 4 is suitably connected with the lower end of the pile, in such a manner that when the pile is rotated said bit will form a hole in advance of the end of the pile. A pipe 5 inserted in this end of the pile and forms an extension of the bore. The lower end of this pipe is enlarged to direct the water to the dilicrent parts of the bit. A second pipe 6 is connected with the upper end of the pile and this pipe has secured thereon the swivel head 7, which receives the hose connection 8 and the shackle- 9. The means for rotating the pile consists of a gear wheel 10 rotatably supported on the base 11 and having teeth 10, and carrying the dogs 12, which are adapted to engage the slots 13 formed in the pile. in this way, when the wheel is rotated by the woru'i shaft 14., driven from any suitable source of power, the dogs will cause the pile to rotate, though said dogs will permit the pile to move longitudinally by gravity or by any suitable driving means.

Having thus described my process what I claim is:

The herein described process of sinking piles consisting in providing the same with. a cutting head at its lower end, rotating the pile to cause the head to form a hole in advance of the pile, introducing a stream or" water at the cutting head and providing jets of water around the body of the pile at intervals throughout its length.
