Pedrail Wheel
The pedrail wheel is a type of all-terrain wheel developed in the late 19th and early 20th century by Londoner Bramah Joseph Diplock. It consists of a series of "feet" (''pedes'' in Latin) connected to pivots on a wheel. As the wheel travels, pressure exerted by springs within it increases the number of feet in contact with the ground, thus reducing ground pressure and allowing the wheel to negotiate obstacles and uneven ground. Definition According to the 1913 Webster's Revised Unabridged Dictionary, a pedrail is: Fiction H. G.

Bramah Joseph Diplock
Bramah Joseph Diplock (27 April 1857 – 9 August 1918) was an English inventor who invented the pedrail wheel in 1899 and the pedrail chaintrack, a type of caterpillar track, in 1907. Diplock was born in Chelsea, London to Thomas Bramah Diplock, a coroner, and Eleanor Diplock. He died suddenly on 9 August 1918 of brain hemorrhage at 21 Heathfield Close, Chiswick, aged 62. Diplock Glacier in Antarctica is named after him due to his contribution to the development of tracked vehicles. Inventions Diplock's first inventions improved traction in geared steam locomotives (both road and rail) by extending drive to all wheels, as well as solving the resulting challenges to also steer the vehicle. Diplock's inventions for these were granted patents dating back to 1893, when he was living in Falmouth, Cornwall. This desire for greater traction in road locomotives (traction engines) probably led directly to the pedrail system which he patented in 1899. In this design the continuous ...

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Webster's Revised Unabridged Dictionary
''Webster's Dictionary'' is any of the US English language dictionaries edited in the early 19th century by Noah Webster (1758–1843), a US lexicographer, as well as numerous related or unrelated dictionaries that have adopted the Webster's name in his honor. "''Webster's''" has since become a genericized trademark in the United States for US English dictionaries, and is widely used in dictionary titles. Merriam-Webster is the corporate heir to Noah Webster's original works, which are in the public domain. Noah Webster's ''American Dictionary of the English Language'' Noah Webster (1758–1843), the author of the readers and spelling books which dominated the American market at the time, spent decades of research in compiling his dictionaries. His first dictionary, ''A Compendious Dictionary of the English Language'', appeared in 1806. In it, he popularized features which would become a hallmark of American English spelling (''center'' rather than ''centre'', ''honor'' rat ...

The Land Ironclads
"The Land Ironclads" is a short story by British writer H. G. Wells, which originally appeared in the December 1903 issue of the ''Strand Magazine''. It features tank-like "land ironclads," armoured fighting vehicles that carry riflemen, engineers, and a captain, and are armed with semi-automatic rifles. Plot summary The story opens with an unnamed war correspondent and a young lieutenant surveying the calm of the battlefield. They reflect philosophically on the war between two unidentified armies. The time appears to be 1903 and the opponents are dug into trenches, each waiting for the other to attack, of the sort then common and being reported on daily from the Boer War. The men on the war correspondent's side are confident they will prevail, because they are all strong outdoor-types – men who know how to use a rifle and fight – while their enemies are townspeople, "a crowd of devitalised townsmen . . . They're clerks, they're factory hands, they're students, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caterpillar Track
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the t ...

Tanks In World War I
A tank is an armoured fighting vehicle intended as a primary offensive weapon in Front line, front-line Land warfare, ground combat. Tank designs are a balance of heavy firepower, strong Vehicle armour, armour, and battlefield Mobility (military), mobility provided by Continuous track, tracks and a powerful engine; their main armament is often mounted within a Gun turret, turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheels
A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for a wheel to rotate, a moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque. Terminology The English word ''wheel'' comes from the Old English word , from Proto-Germanic , from Proto-Indo-European , an extended form of the root . Cognates within Indo-European ...

English Inventions
English inventions and discoveries are objects, processes or techniques invented, innovated or discovered, partially or entirely, in England by a person from England. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two. Nonetheless, science and technology in England continued to develop rapidly in absolute terms. Furthermore, according to a Japanese research firm, over 40% of the world's inventions and discoveries were made in the UK, followed by France with 24% of the world's inventions and discoveries made in France and followed by the US with 20%. The following is a list of inventions, innovations or discoveries known or generally recognised to be English. Agriculture * 1701: Seed drill improved by Jethro Tull (1674–1741). *18th century: of the horse-drawn hoe and scarifier by Jethro Tull * 1780s: Selective breeding and artificial selection pioneered by Robert Bakewell (1725–1795). * 1842: ...
