Abstract
A boring machine includes a cutter head, an internal casing and an auger that is located within the internal casing. The cutter head and the auger are operationally connected to a rotational mechanism. A rear bulkhead is located at the rear end of the auger, and a rear hopper is located behind the rear bulkhead. The boring machine also includes means for directing material cut by the cutter head into the auger so that rotation of the auger will convey such material rearwardly to the rear hopper. The boring machine includes a transverse conveyor located behind the rear bulkhead in the rear hopper which is adapted to convey material out of the rear hopper in a direction transverse to the longitudinal axis of the auger.
