John Braithwaite The Elder
John Braithwaite the elder (1760–1818), was a British engineer, and salvor. John Braithwaite the younger was his son. Life Braithwaite is best known as the constructor of one of the earliest successful forms of diving bell. In 1783 he descended in one of his own construction into the wreck of the Royal George, which had gone down off Spithead in the August of the previous year, and recovered her sheet anchor and many of her guns. In the same year, and by the same means, he recovered a number of guns sunk in the Spanish flotilla off Gibraltar. In 1788, again he made a descent to the wreck of the Hartwell, an East Indiaman, lost off Boa Vista, one of the Cape Verde islands, and recovered dollars to the value of £38,000, 7,000 pigs of lead, and 360 boxes of tin. In 1806, he raised from the Abergavenny, an East Indiaman, lost off Portland, £75,000 worth of dollars, a quantity of tin, and other property to the value of £30,000, and successfully blew up the wreck with gun ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

John Braithwaite (engineer)
John Braithwaite, the younger (19 March 1797 – 25 September 1870), was an English engineer who invented the first steam fire engine. He also co-designed the first locomotive claimed to have covered a mile in less than a minute. Early life Braithwaite was third son of John Braithwaite the elder. He was born at 1 Bath Place, New Road, London, on 19 March 1797, and, after being educated at Mr. Lord's school at Tooting in Surrey, attended in his father's manufactory, where he made himself master of practical engineering, and became a skilled draughtsman. In June 1818 his father died, leaving the business to his sons Francis and John. Francis died in 1823, and John Braithwaite carried on the business alone. He added to the business the making of high-pressure steam-engines. In 1817 he reported before the House of Commons upon the Norwich steamboat explosion, and in 1820 he ventilated the House of Lords by means of air-pumps. In 1822 he made the donkey engine, and in 1823 cast t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westbourne Green
Westbourne Green is an area of Westbourne, London, the centre of the former hamlet of Westbourne, at the north-western corner of the City of Westminster. It is named for its location west of a bourne (small stream). Traditionally a rural area, small-scale building had begun by the 17th century. In the early 19th century much more sustained development occurred as a result of the building of the Grand Union Canal and railways through the area.Willey, Russ.

New Road (London)
The New Road was a toll road built across fields around the northern boundaries of London, the first part of which opened in 1756. The route comprises the modern-day A501 ( Old Marylebone Road, Marylebone Road, Euston Road, Pentonville Road, City Road, and Moorgate). Background In the 18th century London began to grow rapidly. Until 1750 there was only one road crossing over the River Thames, namely London Bridge. But the capital started to sprawl, first along the river from the City to Westminster, and then north past Soho (in medieval times, the king's hunting grounds) to Oxford Street and beyond. The Proceedings of the Old Bailey Online Project give a good overview of the demographic growth of the capital. From the early 19th century, London was the largest city in the world. Early history In 1755 influential residents of St Marylebone, Paddington and Islington, all separate villages close to London, petitioned Parliament for the right to provide a turnpike trust ro ...

St Albans
St Albans () is a cathedral city in Hertfordshire, England, east of Hemel Hempstead and west of Hatfield, Hertfordshire, Hatfield, north-west of London, south-west of Welwyn Garden City and south-east of Luton. St Albans was the first major town on the old Roman Britain, Roman road of Watling Street for travellers heading north and became the city of Verulamium. It is within the London commuter belt and the Greater London Built-up Area. Name St Albans takes its name from the first British saint, Saint Alban, Alban. The most elaborate version of his story, Bede's ''Ecclesiastical History of the English People'', relates that he lived in Verulamium, sometime during the 3rd or 4th century, when Christians were suffering persecution. Alban met a Christian priest fleeing from his persecutors and sheltered him in his house, where he became so impressed with the priest's piety that he converted to Christianity. When the authorities searched Alban's house, he put on the priest's cloa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salvor
Marine salvage is the process of recovering a ship and its cargo after a shipwreck or other maritime casualty. Salvage may encompass towing, re-floating a vessel, or effecting repairs to a ship. Today, protecting the coastal environment from spillage of oil or other contaminants is a high priority. Before the invention of radio, salvage services would be given to a stricken vessel by any ship that happened to be passing by. Nowadays, most salvage is carried out by specialist salvage firms with dedicated crew and equipment. The legal significance of salvage is that a successful salvor is entitled to a reward, which is a proportion of the total value of the ship and its cargo. The amount of the award is determined subsequently at a "hearing on the merits" by a maritime court in accordance with Articles 13 and 14 of the International Salvage Convention of 1989. The common law concept of salvage was established by the English Admiralty Court, and is defined as "a voluntary succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Indiaman
East Indiaman was a general name for any sailing ship operating under charter or licence to any of the East India trading companies of the major European trading powers of the 17th through the 19th centuries. The term is used to refer to vessels belonging to the Austrian, Danish, Dutch, English, French, Portuguese, or Swedish companies. Some of the East Indiamen chartered by the British East India Company were known as "tea clippers". In Britain, the East India Company held a monopoly granted to it by Queen Elizabeth I of England in 1600 for all English trade between the Cape of Good Hope and Cape Horn. This grant was progressively restricted during the late 18th and early 19th centuries, until the monopoly was lost in 1834. English (later British) East Indiamen usually ran between England, the Cape of Good Hope and India, where their primary destinations were the ports of Bombay, Madras and Calcutta. The Indiamen often continued on to China before returning to England via t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hartwell (ship)
''Hartwell'' was a 3-decker ship of the Kingdom of Great Britain, British East India Company (EIC) launched in 1787. On her maiden voyage she ran aground and sank off the Cape Verde Islands off West Africa. Career Caleb Crookenden and Co. of West Itchenor, West Sussex, launched ''Hartwell'' in February 1787, for Captain John Fiott. He claimed she was the largest ship of her kind in the service of the EIC. Captain Edward Fiott sailed ''Hartwell'' from The Downs (ship anchorage), The Downs on 25 April 1787, bound for China. She was on her maiden voyage, loaded with goods including of silver. After severe Atlantic gales, on 20 May, a mutiny broke out when the crew refused to extinguish lights. Fiott arrested and confined three men, but with half the crew still refusing to obey orders, he changed course and headed for the Cape Verde islands, where he intended to hand over the mutineers to the authorities. However, on 24 May ''Hartwell'' ran onto a reef three league (unit), leagues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
