John Fitch (inventor)
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. It was propelled by a bank of oars on either side of the boat. 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 in a manner similar to 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.
Samuel Morey
Morey's first patent, in 1793, was for a steam-powered spit, but he had grander plans. Morey realized that steam could be a power source in the 1780s, and he probably appreciated a steamboat’s potential from work on his father’s ferry and the locks he designed along the Connecticut river. In the early 1790s he fitted a paddle wheel and steam engine to a small boat and powered it up and down the Connecticut River. Legend has it, this was done on a Sunday morning, when the town was at church, to avoid ridicule if he failed.
The most important aspect of this craft was the paddle wheel. It was an old idea – supposedly dating to antiquities – and previously tried with a steam engine. Jonathan Hulls of England used a rear-mounted paddle wheel in 1737 but an inefficient method of turning the steam engine’s reciprocating motion into the circular motion hobbled it. In 1789, Nathan Reed of Massachusetts experimented with a paddle wheel, and considered patenting it, but eventually patented a different method instead. The American John Fitch experimented with side-mounted paddle wheels, but in 1791 used and patented oars instead. Morey's may have been the first successful use of a steam power paddle wheel, which was the best method of propulsion until the propeller, invented by Fitch, was perfected.
