Hollow Auger.
Patent for a new and improved hollow auger. This design "consists in an adjustable hollow auger and an adjustable fore-auger, which are combined together for use with an ordinary brace, and constructed in such a manner that when applied to use the end of the spoke or other article is first beveled by the fore-auger, and the tenon then formed by the hollow auger. The cutters of the fore-auger are formed upon pivoted arms, which are automatically released, and then thrown open by a spring when the spoke is pointed, in order to give opportunity for the hollow auger to act" (lines 16-28).
