The Americans, as already stated, had, also, at an early period turned their attention to new modes of propelling vessels. In 1784, James Rumsey mentioned to General Washington a project of steam navigation, but, having been refused a patent in Pennsylvania, came to England and succeeded in inducing a wealthy countryman of his own, then resident in London, and others, to disburse the expenses of an experiment, for which he obtained a patent in 1788. The particulars of his plan are given at length by Mr. Woodcroft[71] and will also be found in the Rolls Chapel Reports.[72] They were altogether impracticable for any useful purpose. In 1786, Mr. John Fitch, also an American by birth, proposed to use vertical oars worked by cranks turned by a horizontal steam-engine of which the following is an illustration.[73]
Although the Legislature of the State of Pennsylvania had, in 1784, turned a deaf ear to the applications of Messrs. Rumsey and Fitch, these gentlemen, in the following year, obtained from the Legislatures of Virginia and Maryland the exclusive right to run steamboats on the waters of those States, while Pennsylvania and New York having, in 1786, granted to Mr. Fitch himself similar exclusive rights, he in that year made a trial of his machine at Shepherdstown, Pennsylvania, in a boat of 9 tons, obtaining, it is said, the speed of 4 or 5 miles an hour against the current of the Potomac. In 1787, Mr. Fitch[74] built another vessel, 12 feet beam, and 45 feet long, with a 12-inch cylinder, the mode of propulsion being somewhat similar, in which he is reported[75] to have made the trip from Philadelphia to Burlington at an average rate of 7 miles an hour. In 1790, he completed another and a larger boat, propelled in a different manner: and, by referring to the Federal Gazette and Philadelphia Advertiser, of 26th July, 1790, the following advertisement will be found: “The steam-boat sets out to-morrow morning at ten o’clock from Arch Street Ferry, in order to take passengers for Burlington, Bristol, Bordingtown, and Fenton:” there is, therefore, no doubt that this boat actually traded with passengers on the Delaware.
But a glance at the second boat built by Fitch, of which the following is an illustration, will show that the grasshopper paddles which he now employed, however well they may have answered for a time on the smooth waters of the Delaware, were not adapted for the general purposes of navigation any more than the treadles in his first invention.[76] Indeed, Fitch himself did not follow up the line of steam service he had commenced at so early a date, but on the invitation, as he alleged, of the French Government, he soon afterwards visited Paris with the view of constructing vessels on his plan. As he was not, however, supplied with the necessary funds (no doubt arising from the fact that the French engineers were not satisfied with the practicability or desirability of his mode of propulsion) no vessel on his plan was built in France, and he was obliged to return to the United States, at the expense of the American Consul. As no further mention is made of vessels fitted on the plans[77] suggested by Fitch, it may be inferred that they were not adapted for practical or useful purposes, or that the machinery was too complicated or too expensive to work remuneratively.
J. C. Stevens.
In 1791, John Cox Stevens, of New York, commenced improvements on steam navigation; but it was not until 1804 that any of these were carried into practice; and even after an expenditure, as he states, of “twenty thousand dollars,” and the constant devotion “of thirteen years of the best period of his life” to the project, he admits that his attempts were on the whole unsuccessful. These consisted of a plan for propelling a boat 25 feet long and 5 feet wide, by a rotatory engine, on the axle of which revolved a wheel, like a windmill or smoke-jack, worked at the stern, but he found it impossible to preserve a sufficient degree of tightness in the packing of the engine. A second modification of his rotatory apparatus proving on trial no better than the first, he had recourse to Watt’s engine, omitting the beam, and having a cylinder 4½ inches diameter with a nine-inch stroke; the boiler, which was only 2 feet long, 15 inches wide, and 12 inches high, consisting of no less than forty-one copper tubes, each an inch in diameter. This boat (which is interesting as the first in which we have a direct account of the use of tubular boilers) was tried in May 1804, and attained a velocity of 4 miles an hour.[78] After having made repeated trials with her, his son undertook to cross from Hoboken to New York, when, unfortunately, as she approached the wharf, the steam-pipe gave way. The boiler having also been damaged, he constructed another with the tubes placed vertically, and for this, perhaps the only portion of his invention worth securing, he, in the year 1805, obtained a patent in England,[79] where he then resided.
Oliver Evans.
While Fitch and Stevens were employed in the manner I have described, another American citizen, Oliver Evans, an ingenious mechanic, was endeavouring to mature a plan for using steam of a very high pressure, to be employed in propelling waggons on common roads, and in an account of his plans which he published in 1786,[80] he suggests a mode of propelling vessels by steam. From this circumstance he has been regarded by some authors as the contriver of a practicable steam-boat: his pretensions, however, rest solely on his own allegations. He states that, in 1785, he placed his engine, used to cleanse docks, in a boat upon wheels, the combined weight being equal to 200 barrels of flour, which he transported down to the water, and, when it was launched, he fixed a paddle-wheel to the stern, and drove it down the Schuylkill to Delaware and up the Delaware to the city, “leaving all the vessels going up behind me at least half-way, the wind being ahead.”
In 1794, one Samuel Morey, of Connecticut, is said to have built a steam-boat which he propelled at 5 miles an hour on the Connecticut River, and, in 1797, he built another, with side wheels, at Bordentown, New Jersey, which was publicly exhibited and made a passage to Philadelphia, but which does not appear to have been afterwards employed.
