Abstract
An underground horizontal boring apparatus includes a framework having a pair of guide tracks and a carriage connected to the framework for movement along the tracks. The apparatus includes a mechanism for moving the carriage in forward or backward directions along the guide tracks. A drill assembly is mounted to the carriage having a drill motor for rotation of a drill rod releasably coupled thereto. A clamp assembly is mounted to one end of the framework and includes a clamp for selectively gripping the drill rod so as to rotatably release the drill rod from the drill motor when the drill motor is operated in a reverse direction. Upon release, the carriage may be moved to a start position, another drill rod may be attached to the drill motor and first rod, and boring resumed.
