Webster’s 1874 Patent Model For Improvement to the Bessemer Converter
James Fern Webster (1821-1904) was an engineer and prolific inventor of devices for the production of iron, steel and aluminum with over 200 patents in the industry. He developed a process for making the extraction of aluminum sufficiently cost effective for the metal to be used in the manufacture of everyday objects. Prior to this, aluminum was considered a precious metal and bars of aluminum were exhibited alongside the French Crown Jewels in the Paris Exhibition of 1855.
This patent model is Number 90, an improvement on an earlier patent that allowed a traction belt to move the Bessemer converter while working with the iron. Very detailed in design and function, mounted on wood. The base is 15 1/2″ x 12″ x 2.1/2″, 48 pounds.
