Fourness became a practical engineer and invented several labor-saving 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 himself in Sheffield, and afterwards in Gainsborough. In 1788, he was a resident of Elland, Halifax, and there made a steam carriage that was run by a three-cylinder inverted engine. Spur-gearing transmitted the driving power from the crank shaft to the axle. His patent was taken out in conjunction with James Ashworth. This vehicle was mounted on two driving wheels and had a smaller steering wheel in front. GEORGE MEDHURST Born at Shoreham, Kent, England, in February, 1759. Died in September, 1827. Medhurst was educated as a clock maker, but in 1789 started as an engineer. In the same year he secured a patent for a windmill and pumps for compressing air to obtain motive power. One of the first investigators in this direction, the idea on which he worked and which continued to absorb his energy throughout life, was to make use of the wind when it served in order to compress large bodies of air for use when needed. In 1800, he took out a patent on an aeolian engine and demonstrated how carriages could be driven upon the common roads by compressed air stored in reservoirs underneath the body of the vehicle. He also contemplated applying this engine to other useful purposes and calculated that small carriages could be worked by a rotary engine and larger 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 compressed air, and the power to compress the air I obtain generally by wind, assisted and improved by machinery described in this specification, and in order to render my invention universally useful I propose to adapt my machinery and magazine so that it may be charged 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, military stores, etc., and to establish regular stage coaches and wagons throughout the kingdom, to convey goods and passengers, for public accommodation, by erecting windmills, water-mills, etc., at proper intervals upon the roads, to be employed in charging large magazines at these stations with compressed air, or in raising large magazines of water by wind, etc., by the power of which portable magazines may be charged when required by machinery for that purpose."
