Medhurst contemplated establishing regular lines of coaches, with pumping stations at regular stopping places. He endeavored to form a company to work his inventions and develop his plans and published a pamphlet on the subject of compressed air. About 1800, he established himself as a machinist and ironmaster in Denmark street, Soho, and about ten years later was the first to suggest pneumatic tubes for the carriage of parcels or passengers. Some two years later he brought out the proposition for what has come to be known as the atmospheric railway, an appliance for conveying goods and passengers by the power of a piston in a continuous tube laid between the rails. ANDREW VIVIAN A resident of Cornwall, England, Andrew Vivian, a cousin of Richard Trevithick, became much interested in the engineering experiments of his famous relative. He worked with his cousin and particularly assisted him in experiments on steam engines for propelling road carriages. In 1802, he was a joint patentee with Trevithick, in the early steam vehicle that was taken to London and was exhibited in that city, where for a short time it occasioned a great deal of public curiosity. DU QUET A Frenchman who, in 1714, designed a small windmill to give motion to the wheels of his carriages. J. H. GENEVOIS A Swiss clergyman, of the early part of the eighteenth century. He proposed to use windmills or sails on his wagon and by a system of springs to store the energy thus obtained until such time as it should be needed for driving purposes. JOHN DUMBELL In 1808, John Dumbell secured a patent for an engine that had many peculiar features. He planned to have the steam act on a series of vanes, or fliers, within a cylinder, "like the sails of a windmill," causing them to rotate together with the shaft to which they were fixed. Gearing transmitted the motion of this shaft to the driving wheels. The inventor proposed to raise steam by permitting water to drop upon a metal plate, kept at an intense heat by means of a strong fire, which was stimulated by a pair of bellows. WILLIAM BRUNTON Born at Dalkeith, Scotland, May 26, 1777. Died at Camborne, Cornwall, England, October 5, 1857. The eldest son of Robert Brunton, a watch and clock maker, William Brunton studied mechanics first in his father's shop and then in England, under the guidance of his grandfather, who was a colliery viewer. When he was thirteen years of age, in 1790, he began work in the fitting shops of the New Lanark cotton mills of David Dale and Richard Arkwright. Remaining in that establishment for six years he then went to the Boulton & Watt shops, at Soho, where he was gradually promoted, until he finally became the foreman and superintendent of engine manufacturing.
