U.S. patents 16082, dated November 11, 1856, and 16083, dated November 18, 1856. It was not until 1861 that the question arose as to what happened to Kelly's process. Scientific American, 1861, new ser., vol. 5, pp. 148-153. There was no response to this rhetorical question, but a further inquiry as to whether the Kelly patent "could be bought" elicited a response from Kelly.
In a similar application in the previous year, Bessemer had failed to win an extension of his U.S. patent 16082, of November 11, 1856, for the sole reason that his British patent with which it had been made co-terminal had duly expired at the end of its fourteen years of life, and it would have been inequitable to give Bessemer protection in the United States while British iron-masters were not under similar restraint.
