102 Kirk, Alexander Carnegie
[br]b. c.1830 Barry, Angus, Scotlandd. 5 October 1892 Glasgow, Scotland[br]Scottish marine engineer, advocate of multiple-expansion in steam reciprocating engines.[br]Kirk was a son of the manse, and after attending school at Arbroath he proceeded to Edinburgh University. Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.[br]Principal Honours and DistinctionsFellow of the Royal Society of Edinburgh.FMWBiographical history of technology > Kirk, Alexander Carnegie

108 Bramah, Joseph
SUBJECT AREA: Civil engineering, Domestic appliances and interiors, Land transport, Mechanical, pneumatic and hydraulic engineering, Public utilities[br]b. 2 April 1749 Stainborough, Yorkshire, Englandd. 9 December 1814 Pimlico, London, England[br]English inventor of the second patented water-closet, the beer-engine, the Bramah lock and, most important, the hydraulic press.[br]Bramah was the son of a tenant farmer and was educated at the village school before being apprenticed to a local carpenter, Thomas Allot. He walked to London c.1773 and found work with a Mr Allen that included the repair of some of the comparatively rare water-closets of the period. He invented and patented one of his own, which was followed by a water cock in 1783. His next invention, a greatly improved lock, involved the devising of a number of special machine tools, for it was one of the first devices involving interchangeable components in its manufacture. In this he had the help of Henry Maudslay, then a young and unknown engineer, who became Bramah's foreman before setting up business on his own. In 1784 he moved his premises from Denmark Street, St Giles, to 124 Piccadilly, which was later used as a showroom when he set up a factory in Pimlico. He invented an engine for putting out fires in 1785 and 1793, in effect a reciprocating rotary-vane pump. He undertook the refurbishment and modernization of Norwich waterworks c.1793, but fell out with Robert Mylne, who was acting as Consultant to the Norwich Corporation and had produced a remarkably vague specification. This was Bramah's only venture into the field of civil engineering.In 1797 he acted as an expert witness for Hornblower \& Maberley in the patent infringement case brought against them by Boulton and Watt. Having been cut short by the judge, he published his proposed evidence in "Letter to the Rt Hon. Sir James Eyre, Lord Chief Justice of the Common Pleas…etc". In 1795 he was granted his most important patent, based on Pascal's Hydrostatic Paradox, for the hydraulic press which also incorporated the concept of hydraulics for the transmission of both power and motion and was the foundation of the whole subsequent hydraulic industry. There is no truth in the oft-repeated assertion originating from Samuel Smiles's Industrial Biography (1863) that the hydraulic press could not be made to work until Henry Maudslay invented the self-sealing neck leather. Bramah used a single-acting upstroking ram, sealed only at its base with a U-leather. There was no need for a neck leather.He also used the concept of the weight-loaded, in this case as a public-house beer-engine. He devised machinery for carbonating soda water. The first banknote-numbering machine was of his design and was bought by the Bank of England. His development of a machine to cut twelve nibs from one goose quill started a patent specification which ended with the invention of the fountain pen, patented in 1809. His coach brakes were an innovation that was followed bv a form of hydropneumatic carriage suspension that was somewhat in advance of its time, as was his patent of 1812. This foresaw the introduction of hydraulic power mains in major cities and included the telescopic ram and the air-loaded accumulator.In all Joseph Bramah was granted eighteen patents. On 22 March 1813 he demonstrated a hydraulic machine for pulling up trees by the roots in Hyde Park before a large crowd headed by the Duke of York. Using the same machine in Alice Holt Forest in Hampshire to fell timber for ships for the Navy, he caught a chill and died soon after at his home in Pimlico.[br]Bibliography1778, British patent no. 1177 (water-closet). 1784, British patent no. 1430 (Bramah Lock). 1795, British patent no. 2045 (hydraulic press). 1809, British patent no. 3260 (fountain pen). 1812, British patent no. 3611.Further ReadingI.McNeil, 1968, Joseph Bramah, a Century of Invention.S.Smiles, 1863, Industrial Biography.H.W.Dickinson, 1942, "Joseph Bramah and his inventions", Transactions of the Newcomen Society 22:169–86.IMcN -
109 Ferguson, Peter Jack
SUBJECT AREA: Ports and shipping[br]b. 21 July 1840 Partick, near Glasgow, Scotlandd. 17 March 1911 Greenock, Scotland[br]Scottish marine engineer, pioneer of multiple-expansion steam reciprocating machinery.[br]Ferguson was educated at the High School of Glasgow before going on to serve his apprenticeship in the engineering department of Thomas Wingate's shipyard. This yard, situated at Whiteinch, then just outside the Glasgow boundary, built interesting and innovative craft and had a tradition of supplying marine engines that were at the leading edge of technology. On his appointment as Manager, Ferguson designed several new types of engines, and in 1872 he was responsible for the construction of what is claimed to be the world's first triple-expansion engine, predating the machinery on SS Propontis by two years and Napier's masterpiece, the SS Aberdeen, by nine years. In 1885, along with others, he founded the shipyard of Fleming and Ferguson, of Paisley, which in the subsequent eighty-five years was to build nearly seven hundred ships. From the outset they built advanced steam reciprocating machinery as well as dredging and other types of plant. The new shipyard was to benefit from Ferguson's experience and from the inspiration he had gained in Wingate's, where experimentation was the norm.[br]Further ReadingF.M.Walker, 1984, Song of the Clyde.

114 Gaskill, Harvey Freeman
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 19 January 1845 Royalton, New York, USAd. 1 April 1889 Lockport, New York, USA[br]American mechanical engineer, inventor of the water-pumping engine with flywheel and reciprocating pumps.[br]Gaskill's father was a farmer near New York, where the son attended the local schools until he was 16 years old. At the age of 13 he already showed his mechanical aptitude by inventing a revolving hayrake, which was not exploited because the family had no money. His parents moved to Lockport, New York, where Harvey became a student at Lockport Union School and then the Poughkeepsie Commercial College, from which he graduated in 1866. After a period in his uncle's law office, he entered the firm of Penfield, Martin \& Gaskill to manufacture a patent clock. Then he was involved in a planing mill and a sash-and-blind manufactory. He devised a clothes spinner and a horse hayrake, but he did not manufacture them. In 1873 he became a draughtsman in the Holly Manufacturing Company in Lockport, which made pumping machinery for waterworks. He was promoted first to Engineer and then to Superintendent of the company in 1877. In 1885 he became a member of the Board of Directors and Vice-President. But for his untimely death, he might have become President. He was also a director of several other manufacturing concerns, public utilities and banks. In 1882 he produced a pump driven by a Woolf compound engine, which was the first time that rotary power with a crank and flywheel had been applied in waterworks. His design was more compact, more economical and lower in cost than previous types and gave the Holly Company a considerable advantage for a time over their main rivals, the Worthington Pump \& Machinery Company. These steam pumps became very popular in the United States and the type was also adopted in Britain.[br]Further ReadingAs well as obituaries appearing in many American engineering journals on Gaskill's death, there is an entry in the Dictionary of American Biography, 1931, Vol. VII, New York, C.Scribner's Sons.RLHBiographical history of technology > Gaskill, Harvey Freeman
