By a coincidence two others, who chose Kentucky as their home, James Rumsey and Edward West, also were pioneers in this work. Both Fitch and Rumsey in 1784 exhibited their plans to General Washington. While Rumsey made his project public first, by means of a model, Fitch successfully plied a boat on the Delaware in 1785 and Rumsey on the Potomac the following year. Fitch claimed that he told Rumsey of his own plans to effect navigation by steam. In 1794, in the presence of hundreds of citizens, a miniature boat invented by Edward West, who had removed from Virginia to Lexington in 1785, proudly moved through the waters of the town branch of the Elkhorn, which had been dammed up near the center of the city. In 1802 Mr. West secured a patent not only for his steamboat invention, but for a gun lock and a nail cutting and heading machine, the first invention of the kind in the world, reputed to cut five thousand three hundred and twenty pounds of nails in twelve hours. The patent of it sold for $10,000 and its operation enabled Lexington to export nails of her own manufacture to Louisville, Cincinnati, and Pittsburgh. So, while it remained for Robert Fulton in 1807 to gain honor from his invention, yet when in 1813 he brought suit to establish his claims as the inventor of steam navigation, he was defeated by a pamphlet of John Fitch's, which proved conclusively there were inventions that antedated the _Clermont_. OTHER KENTUCKY INVENTIONS In 1792, the year that Kentucky became a state, there came to Lexington a man named Nathan Burrows, who was a pioneer, not only as a settler, but as an inventor of the manufacture of hemp and a machine for cleaning it. He failed to reap any real benefit from this, but later manufactured a mustard that took a premium at the World's Fair in England in 1851. Another resident of Lexington, John Jones, in 1803 invented a machine for sawing stone, and a speeder spindle. It remained for a Kentuckian, Dr. Joseph Buchanan, while a student of medicine at Lexington in 1805, to originate the conception of the music of light to be accomplished by means of harmonific colors, luminously displayed, and to invent an instrument that produced its music from glasses of different chemical composition.
