In 1854, Professor Hughes went to Louisville to superintend the making of his first instrument; but it was unprotected by a patent in the United States until 1855. In that form straight vibrators were used as governors, and a separate train of wheel-work was employed in correcting: but in later forms the spiral governor was adopted, and the printing and correcting is now done by the same action. In 1855, the invention may be said to have become fit for employment, and no sooner was this the case, than Professor Hughes received a telegram from the editors of the New York Associated Press, summoning him to that city. The American Telegraph Company, then a leading one, was in possession of the Morse instrument, and levied rates for transmission of news which the editors found oppressive. They took up the Hughes' instrument in opposition to the Morse, and introduced it on the lines of several companies. After a time, however, the separate companies amalgamated into one large corporation, the Western Union Telegraph Company of to- day. With the Morse, Hughes, and other apparatus in its power, the editors were again left in the lurch.
