William Kelly (Invention)
Birthday 1811: Pittsburgh, Pennsylvania,
William Kelley owned land containing iron
ore where he worked a Cobb furnace. He also had factories for making
sugar-boiling kettles where pig iron was converted to wrought iron. Attempting
to make the converter process more economical he developed a way of removing
excess carbon by burning it out of molten iron with an air blast. He obtained a
patent for this process in 1857.
