Corkscrew

In 1860, M L. Byrn of New York City, N.Y., was issued a patent for an improved corkscrew - a “covered gimlet screw with a ‘T’ handle” (No. 27,615). The inventor claimed the design would provide greater strength and durability and which could be manufactured at less cost than prior construction methods using a spiral twist of steel wire that gradually tapered from the handle to the point. Byrn claimed the gimlet-type screw with wider threads would also be strong enough to “remove a bung of the hardest wood from a barel or hogshead.”
