Deutsches Technikmuseum Berlin, Germany. By 1785, Fitch was done surveying and settled in
Warminster, Pennsylvania, where he began working on his ideas for a steam-powered boat. Unable to raise funds from the
Continental Congress, he persuaded various state legislatures to award him a 14-year
monopoly for steamboat traffic on their inland waterways. With these monopolies, he secured funding from business people and professional citizens in
Philadelphia. Fitch had seen a drawing of an early British
Newcomen atmospheric engine in an encyclopedia, but Newcomen engines were huge structures designed to pump water out of mines. He had somehow heard about the more efficient
steam engine developed by
James Watt in
Scotland in the late 1770s. Still, there was not a single
Watt engine in America at that time, nor would there be for many years (Fulton's exported model in his 1807 steamboat,
Clermont, would be one of the first) because Britain would not allow the export of any new technology to its former colony. As a result, Fitch attempted to design his version of a steam engine. He moved to Philadelphia and engaged the clockmaker and inventor
Henry Voigt to help him build a working model and place it on a boat. The first successful trial run of his
steamboat Perseverance was made on the
Delaware River on August 22, 1787, in the presence of delegates from the
Constitutional Convention. A bank of oars on either side of the boat propelled it. During the next few years, Fitch and Voigt worked to develop better designs, and in June 1790, launched a boat powered by a steam engine driving several stern-mounted oars. These oars paddled like the motion of a swimming duck's feet. With this boat, he carried up to 30 paying passengers on numerous round-trip voyages between Philadelphia and
Burlington, New Jersey during the summer of 1790. Estimates of miles traveled that summer range from 1,300 to 3,000, and Fitch claimed that the boat often went for 500 miles without mechanical problems. Estimated speeds were of a minimum 6 miles per hour under unfavorable conditions, to a maximum of 7 or 8 miles per hour. Fitch was granted a U.S.
patent on August 26, 1791, after a battle with
James Rumsey, who had also invented a steam-powered boat. The newly created federal Patent Commission did not award the broad monopoly patent that Fitch had asked for, but rather a patent of the modern kind for the new design of Fitch's steamboat. It also awarded steam-engine-related patents dated that same day to Rumsey,
Nathan Read, and
John Stevens. The loss of a monopoly due to these same-day patent awards led many of Fitch's investors to leave his company. While his boats were mechanically successful, Fitch no longer had the financial resources to carry on. Fitch's idea would be turned profitable two decades later by
Robert Fulton. Fitch had also received a patent in 1791 from
France, and in 1793, having given up hope of building a steamboat in America, he left for France, where an American investor,
Aaron Vail, had promised to help him build a boat there. But Fitch arrived just as the
Reign of Terror was beginning, and his plans had to be abandoned. He went to
London to attempt it there, but that also failed. He returned to the United States in 1794 and tried a few more times to build a steamboat. Failing this, he moved to
Bardstown, Kentucky, in 1797, where he hoped to sell some of the lands he had acquired in the early 1780s and use the proceeds to build a steamboat for use on the Ohio or Mississippi River. He arrived to find settlers occupying his properties, resulting in legal disputes that occupied him until his death on July 2, 1798. in Bardstown. ==Steam locomotive==
