Henry Maudslay, who trained a school of machine tool makers early in the 19th century, was employed at the Royal Arsenal, Woolwich, as a young man where he would have seen the large horse-driven wooden machines for cannon boring made and worked by the Verbruggans.

During the summer of 1799 Brunel was introduced to Henry Maudslay, a talented machine tool maker who had been a manager for Joseph Bramah, and had recently started his own business.

It was Maudslay who built the lock that was displayed in Bramah ’ s shop window with a notice offering a reward of 200 guineas to anyone who could pick it.

Although Maudslay was not the first person to invent a slide-rest ( as many writers have claimed ), and may not have been the first inventor to combine a lead screw, slide-rest, and set of change gears all on one lathe ( Jesse Ramsden may have done that in 1775 ; evidence is scant ), he is certainly the person who introduced to the rest of the world the winning three-part combination of lead screw, slide rest, and change gears, sparking a great advance in machine tools and in the engineering use of screw threads.

Maudslay also recruited a promising young Admiralty draughtsman, Joshua Field, who proved to be so talented that Maudslay took him into partnership.

The shield was built by Maudslay, Sons & Field, of Lambeth, London, who also built the steam pumps for de-watering the tunnel.

His efforts were augmented by those of Marc Isambard Brunel, who designed most of the machines, and Henry Maudslay, the mechanic who built the machines and became a prominent machine tool builder.

The mechanism was the work of Maudslay, Sons & Field of Lambeth, who had previously constructed the time ball mechanism for Greenwich Observatory.

The legend that Maudslay invented the slide rest originated with James Nasmyth, who wrote ambiguously about it in his Remarks on the Introduction of the Slide Principle, 1841 ; later writers misunderstood, and propagated the error.

A misunderstanding persisted for many years that James Nasmyth had claimed that Maudslay was the original inventor of the slide rest.

A bust of Maudslay. Maudslay had shown himself to be so talented that after one year the nineteen year old was made manager of Bramah ’ s workshop.

The concept of interchangeable parts had been implemented in the early 19th century by inventors including Honoré Blanc, Henry Maudslay, John Hall, and Simeon North.

Once the contract with the Admiralty had been placed he engaged Henry Maudslay to make them, and it is clear the final designs had considerable input from Bentham, Maudslay, Simon Goodrich, ( mechanician to the Navy board ) as well as Brunel himself.

It is likely that Maudslay was not aware of Vaucanson's work, since his first versions of the slide rest had many errors that were not present in the Vaucanson lathe.

Maudslay made working models of the machine for making pulley blocks, and Brunel approached Samuel Bentham, the Inspector General of Naval Works.

Maudslay designed and made a set of special tools and machines that allowed the lock to be made at an economic price.

During the First World War, they made motorcycles, lorries to Maudslay designs, and, not having a suitable one of their own, cars to a Sunbeam design.

This engine was replaced in 1807 in the same house by another, more powerful, table engine made by Fenton, Murray and Wood of Leeds and, in turn, in 1830 by a Maudslay beam engine.

The first historically important intra-company standardization of screw threads began with Henry Maudslay around 1800, when the modern screw-cutting lathe made interchangeable V-thread machine screws a practical commodity.

Henry Maudslay played his part in the development of mechanical engineering when it was in its infancy, but he was especially pioneering in the development of machine tools to be used in engineering workshops across the world.

* John Cantrell and Gillian Cookson, eds., Henry Maudslay and the Pioneers of the Machine Age, 2002, Tempus Publishing, Ltd, pb., ( ISBN 0-7524-2766-0 ) This is a collection of essays by various specialists, and comprises biographies of Maudslay, Roberts, Napier, Clement, Whitworth, Nasmyth and Muir, as well as an account of the London Engineering Scene at the time of Maudslay, and an account of the firm from the death of Maudslay in 1831 until its demise in 1904.

Mechanical engineer and tool-maker Henry Maudslay was an early member and Joseph Whitworth presented one of the earliest papers – it was not until 1847 that the Institution of Mechanical Engineers was established ( with George Stephenson as its first President ).

They also produced Wasp and Dragonfly radial aircraft engines, Tylor truck engines and Maudslay gearboxes as well as being the country's largest maker of depth charge fuzes .. For their efforts during the war Guy received a commendation from William Weir, Secretary of State for Air.

Marc Isambard Brunel ( father of Isambard Kingdom Brunel ), with the help of Henry Maudslay and others, designed 22 types of machine tools to make the parts for the blocks used by the Royal Navy.

The lessons Maudslay learned about the need for stability and precision he adapted to the development of machine tools, and in his workshops he trained a generation of men to build on his work, such as Richard Roberts, Joseph Clement and Joseph Whitworth.

He then moved to London where he found employment working for Henry Maudslay, the inventor of the screw-cutting lathe, alongside such people as James Nasmyth ( inventor of the steam hammer ) and Richard Roberts.

Whitworth developed great skill as a mechanic while working for Maudslay, developing various precision machine tools and also introducing a box casting scheme for the iron frames of machine tools that simultaneously increased their rigidity and reduced their weight.

During the 1790s Henry Maudslay created the first screw-cutting lathe, a watershed event that signaled the start of blacksmiths being replaced by machinists in factories for the hardware needs of the populace.

Maudslay acquired such a good reputation for his skill that Joseph Bramah ( the inventor of the hydraulic press ) called for his services.

Having sent for Maudslay on the recommendation of one of his employees, Bramah was surprised to discover that he was only eighteen, but Maudslay demonstrated his ability and started work at Bramah ’ s workshop in Denmark Street, St Giles.

At the time when Maudslay began working for Bramah, the typical lathe was worked by a treadle and the workman held the cutting tool against the work.

In 1797, after having worked for Bramah for eight years, Maudslay asked for an increase in his wage of only 30s a week.

Maudslay also developed the first industrially practical screw-cutting lathe in 1800, allowing standardisation of screw thread sizes for the first time.

Maudslay also supplied the steam-driven pumps that were so important for keeping the tunnel workings dry.

Others, such as Henry Maudslay, James Nasmyth, and Joseph Whitworth, soon followed the path of expanding their entrepreneurship from manufactured end products and millwright work into the realm of building machine tools for sale.

At 1800 on 15 May, at a meeting in Whitworth's house, Gibson and Wallis briefed four key officers: the squadron's two flight commanders, Squadron Leader Henry Maudslay and Sqn Ldr H. M. " Dinghy " Young ; Gibson's deputy for the Möhne attack, Fl. Lt.

Maudslay ( Z for Zebra ) then attempted a run but the bomb struck the top of the dam and the aircraft was severely damaged in the blast.

* 1873 – Algernon Maudslay, British sailor ( d. 1948 )

Henry Maudslay built a bench micrometer in the early 19th century that was jocularly nicknamed " the Lord Chancellor " among his staff because it was the final judge on measurement accuracy and precision in the firm's work.

The culture of toolroom accuracy and precision, which started with interchangeability pioneers including Gribeauval, Tousard, North, Hall, Whitney, and Colt, and continued through leaders such as Maudslay, Palmer, Whitworth, Brown, Sharpe, Pratt, Whitney, Leland, and others, grew during the Machine Age to become an important part of combining applied science with technology.

* Henry Maudslay, engineer and tool-maker, was born in Salutation Alley ( now demolished ) and buried in the parish churchyard of St Mary Magdalen's.

Newburyport Forest is located in the southwest corner of the city, and Maudslay State Park lies along the northwest part of the city, along the banks of the Merrimack.

Henry Maudslay: Founder of precision engineering and first production line.

Nasmyth therefore decided instead to show Maudslay examples of his skills and produced a complete working model of a high-pressure steam engine, creating the working drawings and constructing the components himself.

In May 1829 Nasmyth visited Maudslay in London, and after showing him his work was engaged as an assistant workman at 10 shillings a week.

Unfortunately, Maudslay died two years later, whereupon Nasmyth was taken on by Maudslay's partner as a draughtsman.

Henry Maudslay ( pronunciation and spelling ) ( 22 August 1771 – 14 February 1831 ) was a British machine tool innovator, tool and die maker, and inventor.

Maudslay came up with the idea of a leather cup washer, which gave a perfect seal but offered no resistance to movement when the pressure was released.
