poses; second 2. pile adopted "for interlocking purposes; third a pile adapted for anchoring to rock or like substance. It is obvious that all three-of these features may be used on the some pile when desired. A fourth feature of my pile, which is avery valuable one-end is simple and conveniently provided in con- .nection with the longitudinal axial opening 853ml elevation of such core; His a detail is than; i may provide o. redial opening near the top of the pile through which water may he led. to the axial opening and by plugging this axial opening above the radial opening and forcing water through the radial opening the material through which the pile is to be driven may be loosened and caused no flow away from the of lhe'pile, greatly feciliealging driving the same. This is a very desirable feature when driving through quicksand or like material.

ly invention is heroine scribed in connection will). the accompanying drawings and the essential characteristics are set forth in the claims.

Referring the drewinqs, Figure l is u side elevefiion of two of the piles showing the interlocking and anchoring features; '2 is :1: plain view of one of the piles showing lhe interlocking members secured in POSlblOll, Fig. 3 is a. horizontal section rter more fully deof one of the members for securing the inborlocking devices in position; Fig. 12 is a detail in the form of a perspective view of a portion of thelower end of the reinforcing described are drawn is as follows: Figs. 1, 5,

'Tliew 1 nethod of anchoring the lower end to rock age-inst. which it is driven and the means by which, I accomplish itis as follows:

The octagonal pile is provided with a longitudinal opening or well extending along its axis from end to end, as indicated at 5. At the lower end the cap member 3 is provided with 2 suitable opening registering with the axial opening of the pile, normally 1 closed by an inverted cone-shaped cap 7 of concrete or like material which may be readily crushed or drilled out by a drilling memher extended downwardly through the opening 5. Whcn the pile is driven down to rock or like material, through which it cannot be driven, a suitable drill is extended downwardly through the opening 5 undoperstedto drill out the concrete ooint 7 and drill downwardly into the rocl a suitable dislance, forming an opening registering with the axial opening The drill is then Withdr Wu and a post or pin such as .indicatedut 8 is droppedfizhrough the opening 5 to the rock at the lower end. This post when it reaches the lower end preferably extends hall of its length into the rock and the other half upwardly into the pile. This post may be made of any suitable material, for example, discarded car axles, mslze'splendid an choring devices for this purpose. -When the anchoring post is in position the opening 5 may be filled with concrete if desired, thereby securely holding the post in position at v the lower end and forming a. solid pile.
