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.
Steamboats of the Mississippi
Steamboats on the Mississippi benefited from technology and political changes. The US bought the Louisiana Purchase from France in 1803. At the time, a semi-bankrupt Napoleon was attempting to extend his hegemony over Europe in what came to be known as the Napoleonic Wars. As a result, the US was then free to expand westward out of the Ohio valley and into the Great Plains and the Southwest.
The success of the "Charlotte Dundas" in Scotland in 1801 and Robert Fulton's "Clermont" on the Hudson River in 1807 proved the concept of the steamboat. At this time, walking beam mill engines, of the Boulton and Watt variety, were dropped onto wood barges with paddles to create an instant powerboat. The overhead engines of the "walking beam" type became the standard Atlantic Seaboard paddle engine for the next 80 years. For smaller boats, Watt perfected the side-lever engine with the engine cut down using side bell-cranks to lower the center of gravity. Sidewheel paddlers were the first to enter the scene. In 1811 the steamer "New Orleans" was built in Pittsburgh for Fulton and Livingston. Fulton started steamboat service between Natchez and New Orleans.
