All the hard work is from blast-furnace iron in this way wasundoubtedly first conceived by an Ameri-can, although he failed to develop the ma-chinery for its use, and, as a consequence,reaped very little benefit from it. WhenWilliam Kelly, who first decarbonized ironby means of an air blast in a furnace hehad erected for that purpose at Eddy-ville, Kentucky, about 1850, came to filehis claim for a patent in 1856 he foundthat Henry Bessemer had filed similarclaims, and had been granted patents afew days previously. Kelly had workedfor years on his scheme, which was iden-tical in principle, but he had n
