Post Auger.
Description:
Patent for a new and improved post-auger. This design "is to improve that class of post-augers whose blades are made adjustable so as to make large or small holes. They have ordinarily been adjusted by means of a bolt, nut, and slot in the blade; but the blades work out of correspondence with each other, the nuts becoming more or less loosened. [This design] dispense[s] with bolt, nut, and slot" (lines 15-23).
