Motorboat Racers At The 1908 Summer Olympics
A motorboat, speedboat or powerboat is a boat that is exclusively powered by an engine. Some motorboats are fitted with inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat has one or more engines that propel the vessel over the top of the water. Boat engines vary in shape, size, and type. Engines are installed ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Kingston Upon Hull
Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, inland from the North Sea and south-east of York, the historic county town. With a population of (), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford. The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed ''Kings-town upon Hull'' in 1299, Hull had been a market town, military supply port, trading centre, fishing and whaling centre and industrial metropolis. Hull was an early theatre of battle in the English Civil Wars. Its 18th-century Member of Parliament, William Wilberforce, took a prominent part in the abolition of the slave trade in Britain. More than 95% of the city was damaged or destroyed in the blitz and suffered a perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priestman Brothers
Priestman Brothers was an engineering company based in Kingston upon Hull, England that manufactured diggers, dredgers, cranes and other industrial machinery. In the later 1800s the company also produced the Priestman Oil Engine, an early design of oil fuelled internal combustion engine. History Priestman family ownership (1870–1895) The company was founded in 1870; William Dent Priestman bought the Holderness Foundry with money from his father, a Leeds corn-miller. William's brother Samuel also joined the company. It is said the company's entry into the construction of dredging equipment began in 1876 when they were asked to construct machinery to recover lost gold from the sea west of the coast of Spain. No gold was found but the company's equipment proved useful for dredging of harbours and docks; the company pioneered the manufacture of steam powered cranes with grab (clamshell) buckets. From 1888 to 1904 the company produced various versions of the Priestman Oil Engine, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch (boat)
Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard. In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces. Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally, these were decked boats, some of which were capable of fast speeds. A powered boat operated by a regulatory or official organisation may be termed a lau ...

Horse Power
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the steam ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilhelm Maybach
Wilhelm Maybach (; 9 February 1846 – 29 December 1929) was an early German engine designer and industrialist. During the 1890s he was hailed in France, then the world centre for car production, as the "King of Designers". From the late 19th century Wilhelm Maybach, together with Gottlieb Daimler, developed light, high-speed internal combustion engines suitable for land, water, and air use. These were fitted to the world's first motorcycle, motorboat, and after Daimler's death, a new automobile introduced in late 1902, the Mercedes model, built to the specifications of Emil Jellinek. Maybach rose to become technical director of the Daimler Motoren Gesellschaft (DMG) but did not get along with its chairmen. As a result, Maybach left DMG in 1907 to found Maybach-Motorenbau GmbH together with his son Karl in 1909; they manufactured Zeppelin engines. After the signing of the Versailles Treaty in 1919 the company started producing large luxury vehicles, branded as "Maybach". He die ...

Gottlieb Daimler
Gottlieb Wilhelm Daimler (; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist born in Schorndorf (Kingdom of Württemberg, a federal state of the German Confederation), in what is now Germany. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine. Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream. In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Petro ...
