Pedrail
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.

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 the 9th 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 were related to improving traction in geared locomotives (both road and rail) by driving all wheels, this presenting problems due to the need to steer the vehicle. His patents date 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 continuously laid tracks contain rollers and the rails r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tanks In World War I
The development of tanks in World War I was a response to the stalemate that developed on the Western Front. Although vehicles that incorporated the basic principles of the tank (armour, firepower, and all-terrain mobility) had been projected in the decade or so before the War, it was the alarmingly heavy casualties of the start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead. In Great Britain, an initial vehicle, nicknamed Little Willie, was constructed at William Foster & Co., during August and September 1915. The prototype of a new design that became the Mark I tank was demonstrated to the British Army on 2 February 1916. Although initially termed "Landships" by the Landship Committee, production vehicles were named "tanks", to preserve secrecy. The term was chosen when it became known that the factory workers at William Foster referred to the first prototype as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheels
A wheel is a circular component that is intended to rotate 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 are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word ''wheel'' comes from the Old English word , from Proto-Germanic , fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar Track
Continuous track is 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 tires 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 tracks provide good trac ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Webster's Revised Unabridged Dictionary
''Webster's Dictionary'' is any of the English language dictionaries edited in the early 19th century by American lexicographer Noah Webster (1758–1843), as well as numerous related or unrelated dictionaries that have adopted the Webster's name in honor. "''Webster's''" has since become a genericized trademark in the United States for 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'' rather th ...

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 philosophically reflecting upon 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 studen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Strand Magazine
''The Strand Magazine'' was a monthly British magazine founded by George Newnes, composed of short fiction and general interest articles. It was published in the United Kingdom from January 1891 to March 1950, running to 711 issues, though the first issue was on sale well before Christmas 1890. Its immediate popularity is evidenced by an initial sale of nearly 300,000. Sales increased in the early months, before settling down to a circulation of almost 500,000 copies a month, which lasted well into the 1930s. It was edited by Herbert Greenhough Smith from 1891 to 1930. The popularity of Sherlock Holmes became widespread after first appearing in the magazine in 1891. The magazine's original offices were on Burleigh Street off The Strand, London. It was revived in 1998 as a quarterly magazine. Publication history ''The Strand Magazine'' was founded by George Newnes in 1890, and its first edition was dated January 1891. The magazine's original offices were located on Burleigh S ...

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 * 1627: Publication of first experiments in Water desalination and filtration by Sir Francis Bacon (1561–1626). * 1701: Seed drill improved by Jethro Tull (1674–1741). *18th century: of the horse-drawn hoe and scarifier by Je ...
