After all our discoveries and inventions no man will go by a pile of wood.
The Baltimore & Ohio railway was to cross his property, and, after various inventions aiming to do away with the locomotive crank and thus save two-fifths of the steam, in 1830 he designed and constructed (largely after plans made two years before) the first steam locomotive built in America; though only a small model it proved the practicability of using steam power for working that line.
He was the author of numerous inventions, including the cagniardelle, a blowing machine, which consists essentially of an Archimedean screw set obliquely in a tank of water in such a way that its lower end is completely and its upper end partially immersed, and operated by being rotated in the opposite direction to that required for raising water.
White's A New Century of Inventions (Manchester, 1822), illustrates possibly the earliest application of this principle to dynamometry.
It is important to remember that the tiaras in old Italian pictures are inventions of the artists and not copied from actual examples.
