21 Lucas, Anthony Francis
SUBJECT AREA: Mining and extraction technology[br]b. 9 September 1855 Spalato, Dalmatia, Austria-Hungary (now Split, Croatia)d. 2 September 1921 Washington, DC, USA[br]Austrian (naturalized American) mining engineer who successfully applied rotary drilling to oil extraction.[br]A former Second Lieutenant of the Austrian navy (hence his later nickname "Captain") and graduate of the Polytechnic Institute of Graz, Lucas decided to stay in Michigan when he visited his relatives in 1879. He changed his original name, Lucie, into the form his uncle had adopted and became a naturalized American citizen at the age of 30. He worked in the lumber industry for some years and then became a consulting mechanical and mining engineer in Washington, DC. He began working for a salt-mining company in Louisiana in 1893 and became interested in the geology of the Mexican Gulf region, with a view to prospecting for petroleum. In the course of this work he came to the conclusion that the hills in this elevated area, being geological structures distinct from the surrounding deposits, were natural reservoirs of petroleum. To prove his unusual theory he subsequently chose Spindle Top, near Beaumont, Texas, where in 1899 he began to bore a first oil-well. A second drill-hole, started in October 1900, was put through clay and quicksand. After many difficulties, a layer of rock containing marine shells was reached. When the "gusher" came out on 10 January 1901, it not only opened up a new era in the oil and gas business, but it also led to the future exploration of the terrestrial crust.Lucas's boring was a breakthrough for the rotary drilling system, which was still in its early days although its principles had been established by the English engineer Robert Beart in his patent of 1884. It proved to have advantages over the pile-driving of pipes. A pipe with a simple cutter at the lower end was driven with a constantly revolving motion, grinding down on the bottom of the well, thus gouging and chipping its way downward. To deal with the quicksand he adopted the use of large and heavy casings successively telescoped one into the other. According to Fauvelle's method, water was forced through the pipe by means of a pump, so the well was kept full of circulating liquid during drilling, flushing up the mud. When the salt-rock was reached, a diamond drill was used to test the depth and the character of the deposit.When the well blew out and flowed freely he developed a preventer in order to save the oil and, even more importantly at the time, to shut the well and to control the oil flow. This assembly, patented in 1903, consisted of a combined system of pipes, valves and casings diverting the stream into a horizontal direction.Lucas's fame spread around the world, but as he had to relinquish the larger part of his interest to the oil company supporting the exploration, his financial reward was poor. One year after his success at Spindle Top he started oil exploration in Mexico, where he stayed until 1905, when he resumed his consulting practice in Washington, DC.[br]Bibliography1899, "Rock-salt in Louisiana", Transactions of the American Institution of Mining Engineers 29:462–74.1902, "The great oil-well near Beaumont, Texas", Transactions of the AmericanInstitution of Mining Engineers 31:362–74.Further ReadingR.S.McBeth, 1918, Pioneering the Gulf Coast, New York (a very detailed description of Lucas's important accomplishments in the development of the oil industry).R.T.Hill, 1903, "The Beaumont oil-field, with notes on other oil-fields of the Texas region", Transactions of the American Institution of Mining Engineers 33:363–405;Transactions of the American Institution of Mining Engineers 55:421–3 (contain shorter biographical notes).WK -
22 Whitworth, Sir Joseph
[br]b. 21 December 1803 Stockport, Cheshire, Englandd. 22 January 1887 Monte Carlo, Monaco[br]English mechanical engineer and pioneer of precision measurement.[br]Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.[br]Principal Honours and DistinctionsBaronet 1869. FRS 1857.
