This construction ermits the introduction and operation of t e sand pump at any time Without the necessity of removing or even stopping the 0 eration of the drill.

1. A, percussive drilling mechanism for sinking shafts of large diameter, comprising an 0 en drill head, a flange extending up War from the drill head and of less diameter than the latter, said flange forming a casing into which the material disintegrated by the action of the drills and the water may pass, said flange forming a sand pump uide. 2. A percussive drilling mec anism for sinking shafts of large diameter, comprising a drill carrying head open for the passage of Water and other material, a casing extendin r upward from the drill head and into which pass, a drill head carrying shaft, and connecting Webs extending from the shaft to the casing.

3. A. percussive drilling mechanism for sinking shafts of large diameter, comprising a drilling head open for the passage of Water and other material, an annular flange eitending upward. from the head and forming a casing into Which such material will pass, a shaft carrying the drill head, Webs connectng the shaft to the casing, and spring erases mounted guiding rollers carried by the upper portion of said flange and arranged to engage with the wall of the shaft being drilled.

4'. in drilling mechanism for sinking shafts of large diameter, an open drill head having a vertically extended casing open at the top, a shaft, a plurality of ribs extending from the shaft to the. casing, and a series of spring pressed anti-friction rollers carried by said casing and arranged to engage the Wall of the shaft at a pointabove the drill head.

5. In percussive drilling mechanism for sinking shaftsof large diameter, a. drill head arran ed to carry a plurality of cutting bits 4 at its lower face, said drill head being open to permit the free passage of Water and other material, and an upwardly extending 0 en flange carried by the drill head and of ess iameter than the latter, the flange forming a sand pum guide.

In percussive drilling mechanism for sinking shafts of large diameter, a drill head open for the passage of Water and other material and having an upwardly extended flange or casing forming a sand pump guide the flange being of less diameter than the drill head, and a drill head carrying shaft, the top of which is in a plane below the top of said flange or casing.

In testimony that I claim the foregoing as my own, I have hereto aflixcd my signature in the presence of two Witnesses.
