126 Crompton, Thomas Bonsor
SUBJECT AREA: Paper and printing[br]b. 1791/2 d. 1858[br]English papermaker and inventor of a, drying machine.[br]The papermaking machine developed by the Fourdrinier brothers in 1807 produced a reel of paper which was cut into sheets, which were then hung up to dry in a loft. The paper often became badly cockled as a result, and ways were sought to improve the drying part of the process. Drying cylinders were introduced, but the first real benefit came from the use of dry felt in Crompton's drying machine. Various materials could be used, but Crompton found that felt made from linen wrap and a woollen weft was best. In 1820 he took out a patent for steam-heated drying cylinders, and in the following year a patent for a cutter to cut the paper reel into sheets. With Crompton's improvements, the papermaking machine assumed its modern form in essentials. In 1839 Crompton installed centrifugal air fans for reciprocating suction pumps in the suction boxes to extract water from the paper on the continuous wire mould. Crompton owned and operated a successful paper mill at Farnworth in Lancashire, supplying the principal merchants and newspaper publishers in London. He was also a cotton manufacturer and, for a time, owned the Morning Post and other newspapers. By the time he died in 1858 he had amassed a considerable fortune.[br]Further ReadingR.H.Clapperton, 1967, The Paper-making Machine, London: Pergamon Press.LRDBiographical history of technology > Crompton, Thomas Bonsor

127 Palmer, John
[br]b. 1743 Bath, Avon, Englandd. 1818 Bath, Avon, England[br]English pioneer in mail transport.[br]He was the son of a brewer and maltster and part-owner of a theatre in Bath. In his early 20s his father sent him to London to organize the petition for a licence for the Orchard Street theatre, which was granted in 1768. He then organized a series of post-chaises to transport ac-tors between this and another theatre in Bristol in which his father also had an interest. By 1782 he had ready a plan for a countrywide service of mail coaches to replace the existing arrangements of conveying the mail by post-boys and -girls mounted on horseback who were by law compelled to carry the mail "at a Rate of Six Miles in the Hour at least" on penalty of one month's hard labour if found loitering. Lord Camden, Member of Parliament for Bath, put Palmer's plan before Prime Minister Pitt, who approved of it. An experimental run was tried on 2 August 1782, a coach leaving Bristol at 4 pm and arriving in London at 8 am the next morning, to return the following night from London at 8 pm and reaching Bristol at 10 am. In March 1785 the Norwich Mail Coach was started and during that year services were started to Portsmouth, Dover, Exeter, Leeds, Manchester, Liverpool, Birmingham, Shrewsbury, Chester, Holyhead, Worcester, South Wales and Milford Haven. A feature of importance was that each mail coach was accompanied by an armed guard. In August 1786 Palmer was appointed Surveyor and Comptroller-General of the Post Office at a salary of £1,500 per annum and a bonus depending on all revenue over £300,000 each year. The popularity of the new service is shown by the feet that by 1813 his 2 1/2 per cent bonus came to £50,000. Due to the intrigues of his deputy, he was removed from office, but he was given a pension of £3,000 a year. He received the freedom of some eighteen towns, was made Mayor of Bath and represented that constituency in Parliament four times.[br]Further ReadingE.Vale, 1960, The Mail-Coach Men, London: Cassell.IMcN -
128 Parsons, Sir Charles Algernon
[br]b. 13 June 1854 London, Englandd. 11 February 1931 on board Duchess of Richmond, Kingston, Jamaica[br]English eingineer, inventor of the steam turbine and developer of the high-speed electric generator.[br]The youngest son of the Earl of Rosse, he came from a family well known in scientific circles, the six boys growing up in an intellectual atmosphere at Birr Castle, the ancestral home in Ireland, where a forge and large workshop were available to them. Charles, like his brothers, did not go to school but was educated by private tutors of the character of Sir Robert Ball, this type of education being interspersed with overseas holiday trips to France, Holland, Belgium and Spain in the family yacht. In 1871, at the age of 17, he went to Trinity College, Dublin, and after two years he went on to St John's College, Cambridge. This was before the Engineering School had opened, and Parsons studied mechanics and mathematics.In 1877 he was apprenticed to W.G.Armstrong \& Co. of Elswick, where he stayed for four years, developing an epicycloidal engine that he had designed while at Cambridge. He then moved to Kitson \& Co. of Leeds, where he went half shares in a small experimental shop working on rocket propulsion for torpedoes.In 1887 he married Katherine Bethell, who contracted rheumatic fever from early-morning outdoor vigils with her husband to watch his torpedo experiments while on their honeymoon! He then moved to a partnership in Clarke, Chapman \& Co. at Gateshead. There he joined the electrical department, initially working on the development of a small, steam-driven marine lighting set. This involved the development of either a low-speed dynamo, for direct coupling to a reciprocating engine, or a high-speed engine, and it was this requirement that started Parsons on the track of the steam turbine. This entailed many problems such as the running of shafts at speeds of up to 40,000 rpm and the design of a DC generator for 18,000 rpm. He took out patents for both the turbine and the generator on 23 April 1884. In 1888 he dissolved his partnership with Clarke, Chapman \& Co. to set up his own firm in Newcastle, leaving his patents with the company's owners. This denied him the use of the axial-flow turbine, so Parsons then designed a radial-flow layout; he later bought back his patents from Clarke, Chapman \& Co. His original patent had included the use of the steam turbine as a means of marine propulsion, and Parsons now set about realizing this possibility. He experimented with 2 ft (61 cm) and 6 ft (183 cm) long models, towed with a fishing line or, later, driven by a twisted rubber cord, through a single-reduction set of spiral gearing.The first trials of the Turbinia took place in 1894 but were disappointing due to cavitation, a little-understood phenomenon at the time. He used an axial-flow turbine of 2,000 shp running at 2,000 rpm. His work resulted in a far greater understanding of the phenomenon of cavitation than had hitherto existed. Land turbines of up to 350 kW (470 hp) had meanwhile been built. Experiments with the Turbinia culminated in a demonstration which took place at the great Naval Review of 1897 at Spithead, held to celebrate Queen Victoria's Diamond Jubilee. Here, the little Turbinia darted in and out of the lines of heavy warships and destroyers, attaining the unheard of speed of 34.5 knots. The following year the Admiralty placed their first order for a turbine-driven ship, and passenger vessels started operation soon after, the first in 1901. By 1906 the Admiralty had moved over to use turbines exclusively. These early turbines had almost all been direct-coupled to the ship's propeller shaft. For optimum performance of both turbine and propeller, Parsons realized that some form of reduction gearing was necessary, which would have to be extremely accurate because of the speeds involved. Parsons's Creep Mechanism of 1912 ensured that any errors in the master wheel would be distributed evenly around the wheel being cut.Parsons was also involved in optical work and had a controlling interest in the firm of Ross Ltd of London and, later, in Sir Howard Grubb \& Sons. He he was an enlightened employer, originating share schemes and other benefits for his employees.[br]Principal Honours and DistinctionsKnighted.
