Morey's experiments seem to have been conducted very quietly, however, and almost nothing is known of them. The author has not been able to learn any particulars of the engines used by him, and nothing definite is known of the dimensions of either boat or machinery. Morey never, like Fitch and Rumsey, sought publicity for his plans or notoriety for himself. NATHAN READ, who has already been mentioned, a native of Warren, Mass., where he was born in the year 1759, and a graduate of Harvard College, was a student of medicine, and subsequently a manufacturer of chain-cables and other iron-work for ships. He invented, and in 1798 patented, a nail-making machine. He was at one time (1800-1803) a Member of Congress, and, later, a Justice of the Court of Common Pleas, and Chief Justice in Hancock County, Me., after his removal to that State in 1807. He died in Belfast, Me., in 1849, at the age of ninety years. In the year 1788 he became interested in the problem of steam-navigation, and learned something of the work of Fitch. He first attempted to design a boiler that should be strong, light, and compact, as well as safe. His first plan was that of the "Portable Furnace-Boiler," as he called it; it was patented August 26, 1791. As designed, it consisted, as seen in Figs. 73 and 74, which are reduced from his patent drawings, of a shell of cylindrical form, like the now common vertical tubular boiler. _A_ is the furnace-door, _B_ a heater and feed-water reservoir, _D_ a pipe leading the feed-water into the boiler,[72] _E_ the smoke-pipe, and _F_ the steam-pipe leading to the engine. _G_ is the "shell" of the boiler, and _H_ the fire-box. The crown-sheet, _I I_, has depending from it, in the furnace, a set of water-tubes, _b b_, closed at their lower ends, and another set, _a a_, which connect the water-space above the furnace with the water-bottom, _K K_. _L_ is the furnace, and _M_ the draught-space between the boiler and the ash-pit, in which the grates are set. [72] This is substantially an arrangement that has recently become common. It has been repatented by later inventors. [Illustration: FIG. 73.--Read's Boiler in Section, 1788.] [Illustration: FIG. 74.--Read's Multi-Tubular Boiler, 1788.] This boiler was intended to be used in both steamboats and steam-carriages. The first drawings were made in 1788 or 1789, as were those of a peculiar form of steam-engine which also resembled very closely that afterward constructed in Great Britain by Trevithick.[73] He built a boat in 1789, which he fitted with paddle-wheels and a crank, which was turned by hand, and, by trial, satisfied himself that the system would work satisfactorily.
