Classification: CPC E | IPC B  E

Claim 3:
4. A drilling machine for angled drilling where the drilling machine has a platform having a longitudinal axis, and a transverse axis; the drilling machine comprising:
a tower for holding a drill string;
a tower interface assembly connected to the platform and supporting the tower;
wherein the tower interface assembly is selectively moveable to tilt the tower in either a plane parallel with the longitudinal axis of the platform, or to tilt the tower in a plane parallel with the transverse axis of the platform; the tower interface assembly comprising:
a frame; the frame moveably connected to the platform;
a pivot shaft; the pivot shaft disposed to allow the tower to tilt in the plane of the longitudinal axis about the pivot shaft;
at least one first cylinder connected between the tower and the platform for causing the movement of the tower in the plane of the longitudinal axis;
a pivoting tilt joint; the pivoting tilt joint moveably joining the frame of the tower interface assembly to the platform for tilt in the plane of the transverse axis;
at least one pivoting connection; the at least one pivoting connection connected to the frame of the tower interface assembly;
at least one second cylinder connected between the pivoting connection and the platform so as to cause the tower interface assembly frame to tilt about the pivoting tilt joint when the second cylinder extends;
at least one pinning cylinder disposed on the tower interface assembly frame; the at least one pinning cylinder having at least one pinning pin; and,
at least one pinning block connected to the platform; the at least one pinning block having a plurality of holes for receiving the at least one pinning pin of the at least one pinning cylinder, so as to selectively lock the tower into a selected tilt in the plane of the transverse axis when the at least one pinning cylinder extends;

whereby the tilted drill string can perform angled drilling in either position.
