About 1780, Dallery made a steam vehicle with a multi-tubular boiler which he claimed was an original invention of his own. This vehicle was run in Amiens and in 1790 was seen on the streets of Paris. In March, 1803, he secured a patent on the tubular boiler for use on his steamboat, or on his steam carriage. This vehicle was a boat-shaped wagon, driven by a steam engine. JAMES WATT Born at Greenock, Scotland, January 19, 1736. Died at Birmingham, Staffordshire, England, August 25, 1819. Watt came of a respectable and industrious family. His grandfather was a professor of mathematics, while his father was an instrument maker, councillor and manufacturer. After a limited education young Watt went to London, in 1755, and became a mathematical and nautical instrument maker. In that capacity he became connected with Glasgow University, and there made his discoveries that resulted in the practical improvements in the steam engine which made him famous. He was associated with Matthew Boulton, under the firm name of Boulton & Watt, from 1774 to 1800, and the Watt engines that were built by that concern at Soho revolutionized England's mining industries. His steam engines represented a great step beyond the Newcomen engines, though still using low-pressure steam. Watt's connection with steam carriages for use on the common roads, a subject that was of much moment in his day, was limited to a single patent and generally to discouraging the plans of others in that direction, owing to his fear that the introduction of high-pressure steam use would harm the engine business. In the patent granted to him in 1784 he proposed that the boiler of his carriage should be made of wooden staves, fastened with iron hoops, like a cask, and the furnace to be of iron, and placed in the inside of the boiler, surrounded with water. Watt, however, never built the steam carriage. He retained the deepest prejudices against the use of high-pressure steam, saying: "I soon relinquished the idea of constructing an engine on this principle; from being sensible it would be liable to some of the objections against Savery's engine, viz., the danger of bursting the boiler, and also that a great part of the power of the steam would be lost, because no vacuum was formed to assist the descent of the piston." ROBERT FOURNESS Born in Otley, Yorkshire, England. Died at an early age.
