Well-Drilling Apparatus.
Patent for a well-drilling apparatus for boring Artesian and other wells. It is meant to "provide simple, efficient, and durable means for expanding or spreading the reamer-blades after the bit-carrying devices have been lowered sufficiently to arrange the reamer-blades below the plane of the lower end of the tubular drill-rod" (lines 10-17). Water pressure is also used to remove the cuttings from the boring-blades. Sections of cable that suspend and lower drill-bit carrying parts into the drill-rod are supported, and sections of drill-rod can be attached and added to the drill-rod. The method of securing the reamer-blades to the reamer-stock is improved with this patent. The parts fit snugly together and prevent water from getting into the drill-rod.
