  • Automatic alignment system for earth boring rig
    Patent number: 4022284
    Abstract: An automatic alignment control system for an earth boring rig utilizes sensor means on the drilling mast for actuating switches connected to power controls. The sensor means reacts to misalignment of the drilling mast vertical axes to close appropriate switches which in turn generate signals to power means which are arranged to shift the mast axes in the appropriate direction for proper vertical alignment.
