SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. June 1836 London, Englandd. 14 October 1897 Eastbourne, Sussex, England[br]English mechanical engineer and author of several volumes of Turning and Mechanical Manipulation.[br]John Jacob Holtzapffel was the second son of Charles Holtzapffel and was educated at King's College School, London, and at Cromwell House, Highgate. Following the death of his father in 1847 and of his elder brother, Charles, at the age of 10, he was called on at an early age to take part in the business of lathe-making and turning founded by his grandfather. He made many improvements to the lathe for ornamental turning, but he is now remembered chiefly for the continuation of his father's publication Turning and Mechanical Manipulation. J.J. Holtzapffel produced the fourth volume, on Plain Turning, in 1879, and the fifth, on Ornamental Turning, in 1884. In 1894 he revised and enlarged the third volume, but the intended sixth volume was never completed. J.J.Holtzapffel was admitted to the Turners' Company of London in 1862 and became Master in 1879. He was associated with the establishment of the Turners' Competition to encourage the art of turning and was one of the judges for many years. He was also an examiner for the City and Guilds of London Institute and the British Horological Institute. He was a member of the Society of Arts and a corresponding member of the Franklin Institute of Philadelphia. He was elected an Associate of the Institution of Civil Engineers in 1863 and became an Associate Member after reorganization of the classes of membership in 1878.[br]Principal Honours and DistinctionsMaster, Turners' Company of London 1879.Bibliography1879, Turning and Mechanical Manipulation, Vol. IV: Plain Turning, London; 1884, Vol. V: The Principles and Practice of Ornamental or Complex Turning, London; reprinted 1894; reprinted 1973, New York.RTSBiographical history of technology > Holtzapffel, John Jacob

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 1806 London, Englandd. 11 April 1847 London, England[br]English mechanical engineer and author of Turning and Mechanical Manipulation.[br]Charles Holtzapffel was the son of John Holtzapffel, a native of Germany who settled in London c.1787 and set up as a manufacturer of lathes and tools for amateur mechanics. Charles Holtzapffel received a good English education and training in his father's workshop, and subsequently became a partner and ultimately succeeded to the business. He was engaged in the construction of machinery for printing banknotes, of lathes for cutting rosettes and for ornamental and plain turning. Holtzapffel is chiefly remembered for his monumental work entitled Turning and Mechanical Manipulation, intended as a work of general reference and practical instruction on the lathe. Publication began in 1843 and only the first two volumes were published in his lifetime. A third volume was edited by his widow from his notes and published shortly after his death. The fourth and fifth volumes were completed by his son, John Jacob Holtzapffel, more than thirty years later. Holtzapffel was an Associate of the Institution of Civil Engineers and served on its Council: he was also a member of the Society of Arts and Chairman of its Committee on Mechanics.RTS -

4 Robinson, George J.
SUBJECT AREA: Textiles[br]b. 1712 Scotlandd. 1798 England[br]Scottish manufacturer who installed the first Boulton \& Watt rotative steam-engine in a textile mill.[br]George Robinson is said to have been a Scots migrant who settled at Burwell, near Nottingham, in 1737, but there is no record of his occupation until 1771, when he was noticed as a bleacher. By 1783 he and his son were describing themselves as "merchants and thread manufacturers" as well as bleachers. For their thread, they were using the system of spinning on the waterframe, but it is not known whether they held a licence from Arkwright. Between 1776 and 1791, the firm G.J. \& J.Robinson built a series of six cotton mills with a complex of dams and aqueducts to supply them in the relatively flat land of the Leen valley, near Papplewick, to the north of Nottingham. By careful conservation they were able to obtain considerable power from a very small stream. Castle mill was not only the highest one owned by the Robinsons, but it was also the highest mill on the stream and was fed from a reservoir. The Robinsons might therefore have expected to have enjoyed uninterrupted use of the water, but above them lived Lord Byron in his estate of Newstead Priory. The fifth Lord Byron loved making ornamental ponds on his property so that he could have mock naval battles with his servants, and this tampered with the water supplies so much that the Robinsons found they were unable to work their mills.In 1785 they decided to order a rotative steam engine from the firm of Boulton \& Watt. It was erected by John Rennie; however, misfortune seemed to dog this engine, for parts went astray to Manchester and when the engine was finally running at the end of February 1786 it was found to be out of alignment so may not have been very successful. At about the same time, the lawsuit against Lord Byron was found in favour of the Robinsons, but the engine continued in use for at least twelve years and was the first of the type which was to power virtually all steamdriven mills until the 1850s to be installed in a textile mill. It was a low-pressure double-acting condensing beam engine, with a vertical cylinder, parallel motion connecting the piston toone end of a rocking beam, and a connecting rod at the other end of the beam turning the flywheel. In this case Watt's sun and planet motion was used in place of a crank.[br]Further ReadingR.L.Hills, 1970, Power in the Industrial Revolution, Manchester (for an account of the installation of this engine).D.M.Smith, 1965, Industrial Archaeology of the East Midlands, Newton Abbot (describes the problems which the Robinsons had with the water supplies to power their mills).S.D.Chapman, 1967, The Early Factory Masters, Newton Abbot (provides details of the business activities of the Robinsons).J.D.Marshall, 1959, "Early application of steam power: the cotton mills of the Upper Leen", Transactions of the Thoroton Society of Nottinghamshire 60 (mentions the introduction of this steam-engine).RLH
