Cullen WhippleBorn 4 Sep 1801; died 23 Oct 1868 at age 67.American inventor and machinist of Providence, RI, who patented the first practical screw machine in the U.S. for making pointed screws (14 Dec 1852, No. 9,477). Early screws had blunt ends, and it was necessary to drill a starter hole. In Oct 1840, he was one of ten incorporators of The New England Screw Co. He invented a machine for the company to use cutting the threads of screws (patented 18 Aug 1842), another for shaving the heads of screws (patented 6 Apr 1843) and one for removing the burs left in cutting the slots in the heads (patented 19 Apr 1843). He invented and patented seven other machines or devices for improving the manufacture of screws, such as a Screw-Blank Feeding mechanism (3 Jun 1856, No.15,052).« |
