82 Brown, Joseph Rogers
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 26 January 1810 Warren, Rhode Island, USAd. 23 July 1876 Isles of Shoals, New Hampshire, USA[br]American machine-tool builder and co-founder of Brown \& Sharpe.[br]Joseph Rogers Brown was the eldest son of David Brown, who was modestly established as a maker of and dealer in clocks and watches. Joseph assisted his father during school vacations and at the age of 17 left to obtain training as a machinist. In 1829 he joined his father in the manufacture of tower clocks at Pawtucket, Rhode Island, and two years later went into business for himself in Pawtucket making lathes and small tools. In 1833 he rejoined his father in Providence, Rhode Island, as a partner in the manufacture of docks, watches and surveying and mathematical instruments. David Brown retired in 1841.J.R.Brown invented and built in 1850 a linear dividing engine which was the first automatic machine for graduating rules in the United States. In 1851 he brought out the vernier calliper, the first application of a vernier scale in a workshop measuring tool. Lucian Sharpe was taken into partnership in 1853 and the firm became J.R.Brown \& Sharpe; in 1868 the firm was incorporated as the Brown \& Sharpe Manufacturing Company.In 1855 Brown invented a precision gear-cutting machine to make clock gears. The firm obtained in 1861 a contract to make Wilcox \& Gibbs sewing machines and gave up the manufacture of clocks. At about this time F.W. Howe of the Providence Tool Company arranged for Brown \& Sharpe to make a turret lathe required for the manufacture of muskets. This was basically Howe's design, but Brown added a few features, and it was the first machine tool built for sale by the Brown \& Sharpe Company. It was followed in 1862 by the universal milling machine invented by Brown initially for making twist drills. Particularly for cutting gear teeth, Brown invented in 1864 a formed milling cutter which could be sharpened without changing its profile. In 1867 the need for an instrument for checking the thickness of sheet material became apparent, and in August of that year J.R.Brown and L.Sharpe visited the Paris Exhibition and saw a micrometer calliper invented by Jean Laurent Palmer in 1848. They recognized its possibilities and with a few developments marketed it as a convenient, hand-held measuring instrument. Grinding lathes were made by Brown \& Sharpe in the early 1860s, and from 1868 a universal grinding machine was developed, with the first one being completed in 1876. The patent for this machine was granted after Brown's sudden death while on holiday.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven: Yale University Press; repub. 1926, New York and 1987, Bradley, Ill.: Lindsay Publications Inc.

83 Case, Jerome Increase
SUBJECT AREA: Agricultural and food technology[br]b. 1819 Williamstown, Oswego County, New York, USAd. 1891 USA[br]American manufacturer and founder of the Case company of agricultural engineers.[br]J.I.Case was the son of a former and began his working life operating the family's Groundhog threshing machine. He moved into contract threshing, and used the money he earned to pay his way through a business academy. He became the agent for the Groundhog thresher in his area and at the age of 23 decided to move west, taking six machines with him. He sold five of these to obtain working capital, and in 1842 moved from Williamstown, New York, to Rochester, Wisconsin, where he established his manufacturing company. He produced the first combined thresher-winnower in the US in 1843. Two years later he moved to Racine, on the shores of Lake Michigan in the same state. Within four years the Case company became Racine's biggest company and largest employer, a position it was to retain into the twentieth century. As early as 1860 Case was shipping threshing machines around the Horn to California.Apart from having practical expertise Case was also a skilled demonstrator, and it was this combination which resulted in the sure growth of his company. In 1869 he produced his first portable steam engine and in 1876 his first traction engine. By the mid 1870s he was selling a significant proportion of the machines in use in America. By 1878 Case threshing machines had penetrated the European market, and in 1885 sales to South America began. Case also became the world's largest manufacturer of steam engines.J.I.Case himself, whilst still actively involved with the company, also became involved in politics. He was Mayor of Racine for three terms and State Senator for two. He was also President of the Manufacturers' National Bank of Racine and Founder of the First National Bank of Burlington. He founded the Wisconsin Academy of Science, Arts and Letters and was President of the Racine County Agricultural Society. He had time for sport and was owner of the world's all-time champion trotter-pacer.Continued expansion of the company after J.I. Case's death led eventually to its acquisition by Tenneco in 1967, and in 1985 the company took over International Harvester. As Case I.H. it continues to produce a full range of agricultural, earth-moving and heavy-transport equipment.[br]Further ReadingDespite the size and importance of the company he created, very little has been written about Case. On particular anniversaries the company has produced celebratory publications, and surprisingly these still seem to be the main source of information about him.R.B.Gray, 1975, The Agricultural Tractor 1855–1950, American Society of Agricultural Engineers (traces the history of power on the farm, in which Case and his machines played such an important role).AP -
84 Howden, James
SUBJECT AREA: Steam and internal combustion engines[br]b. 29 February 1832 Prestonpans, East Lothian, Scotlandd. 21 November 1913 Glasgow, Scotland[br]Scottish engineer and boilermaker, inventor of the forced-draught system for the boiler combustion chamber.[br]Howden was educated in Prestonpans. While aged only 14 or 15, he travelled across Scotland by canal to Glasgow, where he served an engineering apprenticeship with James Gray \& Co. In 1853 he completed his time and for some months served with the civil engineers Bell and Miller, and then with Robert Griffiths, a designer of screw propellers for ships. In 1854, at the age of 22, Howden set up as a consulting engineer and designer. He designed a rivet-making machine from which he realized a fair sum by the sale of patent rights, this assisting him in converting the design business into a manufacturing one. His first contract for a marine engine came in 1859 for the compound steam engine and the watertube boilers of the Anchor Liner Ailsa Craig. This ship operated at 100 psi (approximately 7 kg/cm2), well above the norm for those days. James Howden \& Co. was formed in 1862. Despite operating in the world's most competitive market, the new company remained prosperous through the flow of inventions in marine propulsion. Shipbuilding was added to the company's list of services, but such work was subcontracted. Work was obtained from all the great shipping companies building in the Glasgow region, and with such throughput Howden's could afford research and experimentation. This led to the Howden hot-air forced-draught system, whereby furnace waste gases were used to heat the air being drawn into the combustion chambers. The first installation was on the New York City, built in 1885 for West Indian service. Howden's fertile mind brought about a fully enclosed high-speed marine steam engine in the 1900s and, shortly after, the Howden-Zoelly impulse steam turbine for land operation. Until his death, Howden worked on many technical and business problems: he was involved in the St Helena Whaling Company, marble quarrying in Greece and in the design of a recoilless gun for the Admiralty.[br]Principal Honours and DistinctionsHowden was the last surviving member of the group who founded the Institution of Engineers and Shipbuilders in Scotland in 1857.BibliographyHowden contributed several papers to the Institution of Engineers and Shipbuilders in Scotland.Further ReadingC.W.Munn, 1986, "James Howden", Dictionary of Scottish Business Biography, Vol. I, Aberdeen.FMW -
85 Slater, Samuel
SUBJECT AREA: Textiles[br]b. 9 June 1768 Belper, Derbyshire, Englandd. 21 April 1835 USA[br]Anglo-American manufacturer who established the first American mill to use Arkwright's spinning system.[br]Samuel's father, William, was a respected independent farmer who died when his son was aged 14; the young Slater was apprenticed to his father's friend, Jedediah Strutt for six and a half years at the beginning of 1783. He showed mathematical ability and quickly acquainted himself thoroughly with cotton-spinning machinery made by Arkwright, Hargreaves and Crompton. After completing his apprenticeship, he remained for a time with the Strutts to act as Supervisor for a new mill.At that time it was forbidden to export any textile machinery or even drawings or data from England. The emigration of textile workers was forbidden too, but in September 1789 Slater left for the United States in disguise, having committed the details of the construction of the cotton-spinning machinery to memory. He reached New York and was employed by the New York Manufacturing Company.In January 1790 he met Moses Brown in Providence, Rhode Island, and on 5 April 1790 he signed a contract to construct Arkwright's spinning machinery for Almy \& Brown. It took Slater more than a year to get the machinery operational because of the lack of skilled mechanics and tools, but by 1793 the mill was running under the name of Almy, Brown \& Slater. In October 1791 Slater had married Hannah Wilkinson, and in 1798 he set up his own mill in partnership with his father-in-law, Orziel Wilkinson. This mill was built in Pawtucket, near the first mill, but other mills soon followed in Smithville, Rhode Island, and elsewhere. Slater was the Incorporator, and for the first fifteen years was also President of the Manufacturer's Bank in Pawtucket. It was in his business role and as New England's first industrial capitalist that Slater made his most important contributions to the emergence of the American textile industry.[br]Further ReadingG.S.White, 1836, Memoirs of Samuel Philadelphia (theearliestaccountofhislife).
