JAMES WATT

Born at Greenock, Scotland, January 19, 1736 Died at Birust 25, 1819

Watt carandfather was a professor of mathematics, while his father was an instrument maker, councillor andWatt went to London, in 1755, and became a mathematical and nautical instrument ow University, and there made his discoveries that resulted in the practical iine which made him famous He was associated with Matthew Boulton, under the firines that were built by that concern at Soho revolutionized England's reat step beyond the Newco low-pressure steaes for use on the common roads, a subject that was of enerally to discouraging the plans of others in that direction, owing to his fear that the introduction of high-pressure stearanted to hie 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 ater

Watt, however, never built the steaainst the use of high-pressure stea an engine on this principle; fro sensible it would be liable to soer 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, Yorkshi+re, England Died at an early age

Fourness beca machines One of his first inventions was for a machine to split hides, that was set up and operated in the establishment of his father Later in life he established works for hih In 1788, he was a resident of Elland, Halifax, and there e that was run by a three-cylinder inverted engine

Spur-gearing trans power from the crank shaft to the axle His patent was taken out in conjunction with Ja wheels and had a s wheel in front

GEORGE MEDHURST

Born at Shorehaland, in February, 1759 Died in September, 1827

Medhurst was educated as a clock ineer In the same year he secured a patent for a wind air to obtain ators in this direction, the idea on which he worked and which continued to absorb his energy throughout life, was to e bodies of air for use when needed In 1800, he took out a patent on an aeolian engine and dees could be driven upon the common roads by compressed air stored in reservoirs underneath the body of the vehicle He also conteine to other useful purposes and calculated that ser ones by reciprocating engines with special gear for varying power

In describing his inventions and explaining his ideas regarding compressed air, Medhurst said: ”The power applied to the machinery is coenerally by wind, assisted and improved by machinery described in this specification, and in order to render my invention universally useful I propose to adapt ed by hand, by a fall of water, by a vacuum obtained by wind and also by explosive and effervescent substances, for the rapid conveyance of passengers, mails, dispatches, artillery, e coaches and wagons throughout the kingdoers, for public acco windmills, water-mills, etc, at proper intervals upon the roads, to be eazines at these stations with coazines of water by wind, etc, by the power of which portable ed when required by machinery for that purpose”

Medhurst conteular lines of coaches, with pu 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 pneuers Soht out the proposition for what has come to be known as the atoods 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, beca experiments of his famous relative He worked with his cousin and particularly assisted hies 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 tireat deal of public curiosity

DU QUET

A Frenchive es

J H GENEVOIS

A Swiss clergyhteenth century He proposed to use winds to store the energy thus obtained until such ti purposes

JOHN DUMBELL

In 1808, John Duine 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 windether with the shaft to which they were fixed Gearing trans wheels The inventor proposed to raise stea water to drop upon afire, which was stimulated by a pair of bellows
