Henry Maudslay
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudslay be ...

Woolwich
Woolwich () is a district in southeast London, England, within the Royal Borough of Greenwich. The district's location on the River Thames led to its status as an important naval, military and industrial area; a role that was maintained throughout the 16th to 20th centuries. After several decades of economic hardship and social deprivation, the area now has several large-scale urban renewal projects. Geography Woolwich is situated from Charing Cross. It has a long frontage to the south bank of the Thames river. From the riverside it rises up quickly along the northern slopes of Shooter's Hill towards the common, at and the ancient London–Dover Road, at . The ancient parish of Woolwich, more or less the present-day wards Woolwich Riverside and Woolwich Common, comprises . This included North Woolwich, which is now part of the London Borough of Newham. The ancient parishes of Plumstead and Eltham became part of the civil parish of Woolwich in 1930. Parts of the wards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beresford Square
Beresford Square is a pedestrianised town and market square in Woolwich in the Royal Borough of Greenwich in London, England. It was formed in the early 19th century and was named after the Anglo-Irish general William Beresford, Master-General of the Ordnance and Governor of the Royal Military Academy in Woolwich. With its lively street market and lined with shops, pubs and restaurants, Beresford Square has been the heart of Woolwich for over two centuries. Since 2019 the square is part of a conservation area. Location Beresford Square is situated in central Woolwich, between the town's shopping district and the Royal Arsenal, from which it is separated by the busy A206 road. The western section of this road is called Beresford Street, the eastern section Plumstead Road. The square is largely pedestrianised. To the east lies Woolwich New Road, accessible only for busses. Most of the bus stops are on Woolwich New Road or General Gordon Square, around Woolwich Arsenal station. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw
A screw and a bolt (see '' Differentiation between bolt and screw'' below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a ''male thread'' (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar ''female thread'' (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out. There are many screws for a variety of materials; materials commonly fastened by screws include wood, sheet metal, and plastic. Explanation A screw is a combination of simple machines: it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts as a wedge as it pushes into the fastened material, and th ...

Nut (hardware)
A nut is a type of fastener with a screw thread, threaded hole. Nuts are almost always used in conjunction with a mating bolt (fastener), bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight deformation (engineering)#Elastic deformation, elastic deformation), a slight Tension (physics), stretching of the bolt, and compression (physics), compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare to ...

Maudslay Screw-cutting Lathes Of Circa 1797 And 1800

Hydraulic Press
A hydraulic press is a machine press using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press. Main principle The hydraulic press depends on Pascal's principle-the pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder. Pascal's law: Pressu ...

Guinea (British Coin)
The guinea (; commonly abbreviated gn., or gns. in plural) was a coin, minted in Great Britain between 1663 and 1814, that contained approximately one-quarter of an ounce of gold. The name came from the Guinea region in West Africa, from where much of the gold used to make the coins was sourced. It was the first English machine-struck gold coin, originally representing a value of 20 shillings in sterling specie, equal to one pound, but rises in the price of gold relative to silver caused the value of the guinea to increase, at times to as high as thirty shillings. From 1717 to 1816, its value was officially fixed at twenty-one shillings. In the Great Recoinage of 1816, the guinea was demonetised and the word "guinea" became a colloquial or specialised term. Although the coin itself no longer circulated, the term ''guinea'' survived as a unit of account in some fields. Notable usages included professional fees (medical, legal, etc.), which were often invoiced in guineas, and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bramah Lock
The Bramah lock was created by Joseph Bramah in 1784. The lock employed the first known high-security design. History After attending some lectures on technical aspects of locks, Bramah designed a lock of his own, receiving a patent for it in 1784. In the same year he started the Bramah Locks company at 124 Piccadilly, London. The locks produced by his company were famed for their resistance to lock picking and tampering, and the company famously had a "challenge lock" displayed in the window of their London shop from 1790, mounted on a board containing the inscription: The challenge stood for over 67 years until, at the Great Exhibition of 1851, the American locksmith Alfred Charles Hobbs was able to open the lock and, following some argument about the circumstances under which he had opened it, was awarded the prize. Hobbs' attempt required about 51 hours, spread over 16 days. The Challenge Lock is in the Science Museum in London. An examination of the lock shows that it has ...

Denmark Street
Denmark Street is a street on the edge of London's West End running from Charing Cross Road to St Giles High Street. It is near St Giles in the Fields Church and Tottenham Court Road station. The street was developed in the late 17th century and named after Prince George of Denmark. Since the 1950s it has been associated with British popular music, first via publishers and later by recording studios and music shops. A blue plaque was unveiled in 2014 commemorating the street's importance to the music industry. The street was originally residential, but became used for commercial purposes in the 19th century. At first, metalwork was a popular trade but it became most famous as Britain's "Tin Pan Alley" housing numerous music publishers' offices. This market declined in the 1960s to be replaced by music shops and independent recording studios. The Rolling Stones recorded at Regent Sound Studio at No. 4 and popular musicians, including David Bowie and the Small Faces, often so ...

Joseph Bramah
Joseph Bramah (13 April 1748 – 9 December 1814), born Stainborough Lane Farm, Stainborough, in Barnsley, Yorkshire, was an English inventor and locksmith. He is best known for having improved the flush toilet and inventing the hydraulic press. Along with William Armstrong, 1st Baron Armstrong, he can be considered one of the two fathers of hydraulic engineering. Early life Joseph Bramah was the second son in the family of Joseph Bramma (note the different spelling of the surname), a farmer, and his wife, Mary Denton. He was educated at the local school in Silkstone and on leaving school he was apprenticed to a local carpenter. On completing his apprenticeship he moved to London, where he started work as a cabinet-maker. In 1783 he married Mary Lawton of Mapplewell, near Barnsley, and the couple set up home in London. They subsequently had a daughter and four sons. The couple lived first at 124 Piccadilly, but later moved to Eaton Street, Pimlico. Improved water closet In ...

Horizontal Boring Machine
A horizontal boring machine or horizontal boring mill is a machine tool which bores holes in a horizontal direction. There are three main types — table, planer and floor. The table type is the most common and, as it is the most versatile, it is also known as the universal type. A horizontal boring machine has its work spindle parallel to the ground and work table. Typically there are three linear axes in which the tool head and part move. Convention dictates that the main axis that drives the part towards the work spindle is the Z axis, with a cross-traversing X axis and a vertically traversing Y axis. The work spindle is referred to as the C axis and, if a rotary table is incorporated, its centre line is the B axis. Horizontal boring machines are often heavy-duty industrial machines used for roughing out large components, but there are high-precision models too. Modern machines use advanced computer numerical control (CNC) systems and techniques. Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Verbruggen
Jan Verbruggen (1712 – 27 October 1781) was a Dutch master gun-founder in the Netherlands and later at the Royal Arsenal in Woolwich, London. He was also an artist. Early life and career He was born in 1712 in Enkhuizen in the Netherlands, son of Pieter Verbruggen and Maria Brouwer. In 1734 he married Eva van Schaack, and they had three children.De Vries van DoesburghVERBRUGGEN (Jan) ''Nieuw Nederlandsch Biografisch Woordenboek''. Volume 3, page 1282. In 1740, he became gun-founder of the Dutch admiralty's foundry in Enkhuizen, and from June 1755 he was master gun-founder in The Hague. After a few years he was suspended, the guns produced being considered unsound; his attempt in 1763 to obtain an appointment at the Royal Arsenal in Woolwich, London was unsuccessful. Artist Verbruggen, a student of the artist Jan van Call the Younger, was also a painter of seascapes and coastal scenery, such as pictures of yachts and East Indiamen at or near Enkhuizen.
