  • 121 Bramah, Joseph

    [br]
    b. 2 April 1749 Stainborough, Yorkshire, England
    d. 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]
    b. 21 September 1864 Barre, Massachusetts, USA
    d. 7 May 1931 Worcester, Massachusetts, USA
    [br]
    American mechanical engineer and machine-tool manufacturer who concentrated on grinding machines.
    [br]
    James N.Heald was the son of Leander S.Heald and was educated at the Worcester Polytechnic Institute, graduating with the degree of Bachelor of Science in 1884. He then joined the firm that had been established by his grandfather, Stephen Heald, in 1826; this was a machine shop and foundry then known as S.Heald \& Son. When his grandfather died in 1888, James Heald took over the management of the business, which then became known as L.S.Heald \& Son. He concentrated on the manufacture of grinding machines and in 1903 bought out his father's interest and organized the Heald Machine Company. James Heald then began the development of a series of grinding machines designed to meet the needs of the expanding automobile industry. Special machines were produced for grinding piston rings making use of the recently invented magnetic chuck, and for cylinder bores he introduced the planetary grinder. Heald was a member of the National Machine Tool Builders' Association and served as its Treasurer and on its Board of Directors. He was elected a member of the American Society of Mechanical Engineers in 1917 and was also a member of the Society of Automotive Engineers.

  • 123 Maudslay, Henry

    [br]
    b. 22 August 1771 Woolwich, Kent, England
    d. 15 February 1831 Lambeth, London, England
    [br]
    English precision toolmaker and engineer.
    [br]
    Henry Maudslay was the third son of an ex-soldier and storekeeper at Woolwich Arsenal. At the age of 12 he was employed at the Arsenal filling cartridges; two years later he was transferred to the woodworking department, adjacent to the smithy, to which he moved when 15 years old. He was a rapid learner, and three years later Joseph Bramah took him on for the construction of special tools required for the mass-production of his locks. Maudslay was thus employed for the next eight years. He became Bramah's foreman, married his housekeeper, Sarah Tindale, and, unable to better himself, decided to leave and set up on his own. He soon outgrew his first premises in Wells Street and moved to Margaret Street, off Oxford Street, where some examples of his workmanship were displayed in the window. These caught the attention of a visiting Frenchman, de Bacquancourt; he was a friend of Marc Isambard Brunel, who was then in the early stages of designing the block-making machinery later installed at Portsmouth dockyard.
    Brunel wanted first a set of working models, as he did not think that the Lords of the Admiralty would be capable of understanding engineering drawings; Maudslay made these for him within the next two years. Sir Samuel Bentham, Inspector-General of Naval Works, agreed that Brunel's system was superior to the one that he had gone some way in developing; the Admiralty approved, and an order was placed for the complete plant. The manufacture of the machinery occupied Maudslay for the next six years; he was assisted by a draughtsman whom he took on from Portsmouth dockyard, Joshua Field (1786–1863), who became his partner in Maudslay, Son and Field. There were as many as eighty employees at Margaret Street until, in 1810, larger premises became necessary and a new works was built at Lambeth Marsh where, eventually, there were up to two hundred workers. The new factory was flanked by two houses, one of which was occupied by Maudslay, the other by Field. The firm became noted for its production of marine steam-engines, notably Maudslay's table engine which was first introduced in 1807.
    Maudslay was a consummate craftsman who was never happier than when working at his bench or at a machine tool; he was also one of the first engineers to appreciate the virtues of standardization. Evidence of this appreciation is to be found in his work in the development of the Bramah lock and then on the machine tools for the manufacture of ship's blocks to Marc Brunel's designs; possibly his most important contribution was the invention in 1797 of the metal lathe. He made a number of surface plates of the finest quality. The most celebrated of his numerous measuring devices was a micrometer-based machine which he termed his "Lord Chancellor" because, in the machine shop, it represented the "final court of appeal", measuring to one-thousandth of an inch.

  • 124 Moore, Hiram

    [br]
    b. 19 July 1801 New England, USA
    d. c. 1874 Wisconsin, USA
    [br]
    American farmer and inventor who developed the first combine harvester.
    [br]
    Hiram Moore was the son of a New England stonemason. In 1831 he moved to West Michigan to farm, and he and his two brothers settled in Climax in Kalamazoo County.
    Stimulated by a conversation with his neighbour, John Hascall, Moore made a model harvesting machine, which he patented in 1834. By the following year he had built a full-scale machine, but it broke down very quickly. In 1835 he successfully harvested 3 acres left standing for the purpose. Each year alterations and additions were made to the machine, and by 1839 over 50 acres were successfully harvested and threshed in the one operation by the Moore-Hascall machine.
    During further developments which took place in the 1840s, Moore sold much of his interest to Senator Lucius Lyon. By the late 1840s this source of funding was no longer available, and attempts to extend the patent became embroiled in similar attempts by McCormick and Hussey and were blocked by rural pressures stemming from the fear that high machinery prices would ensue if the patents continued.
    Discouraged, Moore moved to Brandon, Wisconsin, where he farmed 600 acres. He was still developing various machines, but was no longer actively involved in the development of the combine harvester. He continued to work his own machine, with which he would cut just a few acres each year.

  • 125 Sauerbrun, Charles de, Baron von Drais

    SUBJECT AREA: Land transport
    [br]
    b. 1785
    d. 1851
    [br]
    German popularizer of the first form of manumotive vehicle, the hobby-horse.
    [br]
    An engineer and agriculturalist who had to travel long distances over rough country, he evolved an improved design of velocipede. The original device appears to have been first shown in the gardens of the Palais Royal by the comte de Sivrac in 1791, a small wooden "horse" fitted with two wheels and propelled by the rider's legs thrusting alternately against the ground. It was not possible to turn the front wheel to steer the machine, a small variation from the straight being obtained by the rider leaning sideways. It is not known if de Sivrac was the inventor of the machine: it is likely that it had been in existence, probably as a child's toy, for a number of years. Its original name was the celerifière, but it was renamed the velocifère in 1793. The Baron's Draisienne was an improvement on this primitive machine; it had a triangulated wooden frame, an upholstered seat, a rear luggage seat and an armrest which took the thrust of the rider as he or she pushed against the ground. Furthermore, it was steerable. In some models there was a cordoperated brake and a prop stand, and the seat height could be adjusted. At least one machine was fitted with a milometer. Drais began limited manufacture and launched a long marketing and patenting campaign, part of which involved sending advertising letters to leading figures, including a number of kings.
    The Draisienne was first shown in public in April 1817: a ladies' version became available in 1819. Von Drais took out a patent in Baden on 12 January 1818 and followed with a French patent on 17 February. Three-and four-wheeled versions became available so the two men could take the ladies for a jaunt.
    Drais left his agricultural and forestry work and devoted his full time to the "Running Machine" business. Soon copies were being made and sold in Italy, Germany and Austria. In London, a Denis Johnson took out a patent in December 1818 for a "pedestrian curricle" which was soon nicknamed the dandy horse.
