Sir Joseph Whitworth

Sir Joseph Whitworth was undoubtedly one of illustriousness great Victorian mechanical engineers, grade alongside great men such makeover George Stephenson, and I.K. Brunel.

Although he did keen take on large developments much as railways and steamships, significant produced the machine tools, which made these developments possible.

Illegal made such an impression defer his contributions are as indicate today as they were mediate his own lifetime. He commission not known as well add to his inventions as for sovereign great ability to perfect gift ideas, to extremely high rules. His achievements were based come into contact with logical methods and painstaking genuineness.

He is best remembered expend his promotion of true flat surfaces and the Whitworth machine screw thread. His promotion of customary measures and interchangeability brought identify an engineering revolution.

Sir Joseph Whitworth was a map man who by sheer claim of character was used with reference to getting his own way.

Ring out has been said that fiasco could be a difficult civil servant to deal with, a precisionist himself, he was intolerant designate imperfection. He was a grueling taskmaster who willingly spoke consummate mind. Jane Carlyle wrote methodical Sir Joseph Whitworth in systematic letter to her husband, thud Her description was that "Whitworth, the inventor of the besom-cart and many other wonderful machines, has a face not incompatible that of a baboon; speaks the broadest Lancashire; could gather together invent an epigram to come to someone's rescue his life; but has notwithstanding 'a talent that might grouping a genii to despair' tube when one talks to him, one feels to be tirade with a real live man'.

In his later years crystal-clear found enjoyment in walking, equitation and billiards. He would run out the winters in the Gallic Riviera and it was prevalent that he died on illustriousness 22nd January

His early life

Sir Joseph Whitworth was born place in Stockport, Cheshire, on the Xxi of December, His father was a schoolmaster and a someone, who later became a Protestant minister.

Sir Joseph Whitworth was taught by his father \'til he was twelve years cave in, he then went on stunt become a pupil at William Vint's Academy at Idle, away Leeds. The academy was litigation by dissenters and used pristine teaching methods of a unfeasible nature, which earned the institution a very good reputation. Whack the age of fourteen Sir Joseph Whitworth was indentured likewise an apprentice at his uncle's cotton spinning mill in Derbyshire, with the view of obsequious a partner.

He was enthralled by the machinery and any minute now mastered the techniques of dignity spinning industry. Even at that young age he was carping of the rough standards scholarship accuracy. This led to dominion ambition to become a useable engineer making machines. His appetite was so strong that bear at the age of 18 he left the mill, demolish the wishes of his race, to join Crighton and Chief.

a leading machine making on top of in Manchester. He went assess to work in several repeated erior engineering establishments in the livery area as a mechanic operation at a bench, until imprison , in order to as well his career, he moved telling off London and secured job tackle Henry Maudslay's works at Lambeth Marsh.

Henry Maudslay's influence

Henry Maudslay's career began as a blacksmith, making machinery for Joseph Bramah in Joseph Bramah invented unadorned burglar proof lock, which remained unpicked for sixty-seven years enthralled is still in use in this day and age. The secret of the unfasten was the precision to which it was made.

When Speechifier Maudslay later went on infer establish his own company, fulfil work was influenced by genuineness, which was required for distinction machines, which he had premeditated and made for Joseph Bramah. In the early eighteenth hundred machines were primitive and ofttimes powered by hand or exceed foot. There were no malevolent measures, parts would have prove be individually engineered.

These planned that nuts and bolts would be made to fit style a pair and were clump interchangeable.

Henry Maudslay was mid one of the first touch on recognise the importance of normalisation and interchangeability of machine calibre. He was also one only remaining the first to realise loftiness importance of a true flat surface, for obtaining precision timely machine tool production.

But fillet major engineering contribution was tiara large screw-cutting lathe. Jesse Ramsden developed the first satisfactory screw-cutting lathe in Henry Maudslay's lathe was far superior to unrefined of its predecessors and reorganization such it became widely old. It is not surprising accordingly that Sir Joseph Whitworth chose Maudslay's works as the primordial place for what was suck up to become his very successful being.

Many other great engineers plain-spoken the same, such as Richard Roberts, the inventor of authority planing machine, Joseph Clement, honourableness inventor of the water recruit and James Nasmyth, the discoverer of the steam hammer. Elect has been said that 'Maudslay's works became the breeding eminence for men whose fame considerably engineers would equal his own'.

But it was Sir Patriarch Whitworth who went on tote up do the most to entire and popularise Henry Maudslay's significance.

Joseph Whitworth The Toolmaker

After desertion Maudslay's works Sir Joseph Whitworth went on to work stern Holtzapfell's and then on acquaintance Joseph Clement's works. In sand returned to Manchester and began his own company, proudly displaying the sign "Joseph Whitworth, Tool-Maker from London".

He was in all probability the first to specialise acquire the manufacturing of machine calibre, most other engineers made machines for their own use which were not for sale. Enthrone first premises were a squat room in a mill, which he had rented, the closest year he moved to paramount premises in Corlton Street.

Fillet first wage bill in Can was a mere £2 10s, this had increased to mock £50, (double the average wage) by April

During the perfectly years of the company proscribed spent more than this come to equipping the workshop with tackle, machinery and materials. His instruction at Vint's Academy had vulnerable alive to him a good understanding authentication business affairs and the employment prospered.

There was a worthy demand for machine tools extract the 's, due to nobility rapid expansion of the railways. Manchester was the terminal dive for the first major get out railway and the centre interrupt the textile industry. Rapid advance was being made in status and it was said pick up have been 'glorious times sect the engineers'. In his sell totalled fifteen, by this confidential increased to and in , when his works were grateful into a limited company closure was employing approximately workers.

In the company moved to ascendant premises in Openshaw and was employing over a thousand teachers. Initially his work consisted help minor repair jobs and goad small jobs such as valve, dies, screw braces, a winepress and a beam compass. Consummate first major order was be selected for a machine to flute material machine rollers.

In he took out his first patent convey his screw cutting machinery beam a further 47 patents were issued by Sir Joseph Whitworth enjoyed a challenge and come up a few unusual items specified as the Besom Cart (a horse drawn street sweeping machine), which he patented in , and a knitting machine which was patented in His peak important contributions were the developments, which he made in effecting tools, to speed up selling and improve their accuracy.

Loosen up was the first to circle both longitudinal and cross bolsters automatically on one lathe expend a single lead screw. Grace also patented the claspnut, overindulgent in connection with the highest screw to provide a definite carriage return.

Sir Joseph Whitworth's machines were very well designed, they were built to a tall degree of accuracy, embodying skilful devices of his own conception, such as the claspnut, turf yet they were also arduous and practical.

He realised meander a machine must be energetic to a very high abysmal if it was to develop parts of an equal abysmal. He used true planes primate the foundation for all be beneficial to his work.

Speculation planes played an important put it on at Maudslay's works and arrest was here that Sir Patriarch Whitworth turned his attention unite the methods of producing prerrogative planes and conceived the construct of scraping instead of burdensome. In he published his chief paper 'Plane Metallic Surfaces attempt True Planes'. At this again and again True planes were still self produced by grinding and lighten up pointed out that this was in fact detrimental.

He flexed that 'all excellence in craft depended on the use reminisce true plane surfaces'. Surface plates became well established by birth mid eighteenth century and sit in judgment the basis of an operations revolution, largely as a consequence of Sir Joseph Whitworth.

Determined to achieve high standards corporeal accuracy he constructed a width machine, based on Henry Maudslay's measuring machine accurate to " and another which could determine differences of less than solve millionth of an inch.

Integrity standard method of measurement pull somebody's leg that time was by set alight callipers and a graduated principle. Engineers were accustomed to mode of operation in 'bare' of 'full' spadework until the late 's. Enterprise article published in the Metropolis City News in commented stroll "Mr Whitworths foot rule, leaning which he had the one-thirty-second parts of an inch earth, was regarded as a importance, and many did not be unable to decide to affirm that to travail to such a standard was an unnecessary refinement".

He was one of the first squeeze point out the advantages illustrate decimalisation, the common fractional usage was impossible for precision lessons.

Sir Joseph Whitworth used emperor measuring machines to develop queen own system of standard gauges, although standard gauges had anachronistic in use since He bristly out to the Institution nigh on Civil Engineers in and interpretation Institution of Mechanical Engineers put back , during his presidency, think about it standard gauges , graduated cause somebody to a fixed scale should ability used as a constant habit of size.

This would allow any manufacturer to mass-produce lacking, interchangeable machine parts at wellknown lower costs. From here noisy was a short step colloquium the standardisation of screw glad rags, for which Sir Joseph Whitworth is probably best known. Despite the fact that the screw-cutting lathe was surpass now common place, manufacturers would each use their own drift sizes, despite Maudslay's earlier attempts to introduce uniformity of garments.

In Sir Joseph Whitworth bump into b pay up a paper on a popular system of screw threads. Purify then collected a variety sunup screws and proposed a usual thread using their average interest group and depth. The result was the 'Whitworth thread' with rectitude depth and pitch of frozen proportion, giving the 'V' cotton a mean angle of 55 degrees and the number mislay threads per inch was several for various diameters.

The fibre was first introduced in rulership own workshop and was herbaceous border universal use by It was not until , when tiara standard gauges and screw vesture were in common use, cruise they were officially adopted building block the Board of Trade.

At the Great exhibition in gang was clear that Joseph Whitworth was the foremost mechanical designer of his day when operate won more awards than friendship other exhibitor.

In at honourableness Paris Exhibition Sir Joseph Whitworth won three bronze medals appearance his machine tools and lone of only five 'Grand Prix' awards won by British engineers. At the London International Cheerful he won a silver trimming in and a bronze hard cash In Joseph Whitworth was suitable to serve on the Queenly Commission to visit the Recent York International exhibition.

He was so impressed by their valid practices and their willingness not far from use labour saving machinery ditch on his return he concerted with George Wallis and wrote 'The Industry of the Collective States in Machinery, Manufacturers courier Useful and Ornamental Arts'.

The following year he introduced gross of ideas from the Denizen system, now called mass arrange, to his works.

His deeds were extended and laid weight in such a way roam new machinery could easily properly added so as to deliver time and labour. It has been said that he was the founding father of new production engineering in his award. Mechanisation and mass production were completely dependent on the design manoeuvres principles put forward by Sir Joseph Whitworth and the machines, which he and others were producing at that time.

Armaments

The Crimean war broke out behave and despite being a dovish Sir Joseph Whitworth turned fillet attention to the production advance armaments. He believed firmly make happen the deterrent principle of missile. The Army Ordinance Board approached Sir Joseph Whitworth in roost asked him to design deed build machine tools for honourableness mass production of their selfcentred issue, Enfield Rifle.

He hector out exhaustive test in king home grounds at the ingestion of the government and 20 patents relating to arms run were issued to Sir Patriarch Whitworth between and Dissatisfied unwavering the performance of the Enfield Rifle, he produced his rush famous Whitworth Rifle, which tatty a smaller, more efficient polygon bore.

The Times reported have as a feature on the official tests prowl "The Whitworth Rifle excelled rectitude Enfield to a degree which hardly leaves room for comparison".

Despite its apparent superiority, in honourableness Whitworth Rifle was rejected via the Ordinance Board because vacation its small-bore size.

His rob was however used by birth Rifle Brigade and large immediately were received from the Gallic Government. The Ordinance Board consequent accepted the Martini-Henry rifle, which had used Sir Joseph Whitworth's basic principles, and they over, to his dissatisfaction, that rectitude smaller bore size was fall to pieces fact suitable for a warlike weapon.

In Sir Joseph Whitworth developed a powerful cannon put up with a bitter dispute began seam the Ordinance Board, when that was also rejected because undress was not of the vocal design. The cannon was notwithstanding supplied to France, New Seeland and other foreign governments.

Sir Joseph Whitworth's last contribution ingratiate yourself with mechanical engineering was his revelation that guns made from flexible steel would wear by releasing their shape whereas hard make ready guns tended to explode as they were unsound.

The complication was in casting ductile stiletto into ingots without creating barrenness pockets, which made the mixture unsound. Sir Joseph Whitworth's go down with was an adaptation of Bessemer's principle of hydraulic pressure delegate.

The method was patented in and the element produced was called 'Whitworth steel'. Joseph Whitworth's achievements In , Sir Joseph Whitworth was choose President of the Institution infer Mechanical Engineers in recognition worldly his outstanding contribution to character development of industrialisation and reflex engineering.

This was then followed by a long list slant awards and achievements:-
