1790 Patented a machine for making nails from prepared rod by drawing it between rollers having cavities corresponding to the shape of the nail. In December of the same year he patented a process for drawing bars or plates to a varying thickness and cutting the nails from there by a punch. Machines of this kind were in operation at Messrs French's factory in Wineborne (Messrs Finch, Wombourne?), Staffordshire in 1792.[1]
Clifford was in partnership with Sheffield-born Richard Wells, who had emigrated to America in 1750 and, by 1790 had established a hardware business in Philadelphia. Clifford's 1790 patents were numbered 1762 and 1785.[2]
