Halftracks
A half-track is a civilian or military vehicle with regular wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. The purpose of this combination is to produce a vehicle with the cross-country capabilities of a tank and the handling of a wheeled vehicle. Performance The main advantage of half-tracks over wheeled vehicles is that the tracks reduce the pressure on any given area of the ground by spreading the vehicle's weight over a larger area, which gives it greater mobility over soft terrain like mud and snow, while they do not require the complex steering mechanisms of fully tracked vehicles, relying instead on their front wheels to direct the vehicle, augmented in some cases by track braking controlled by the steering wheel. It is not difficult for someone who can drive a car to drive a half-track, which is a great advantage over fully tracked vehicles, which require specialized training. Half-tracks thus fa ...

Kégresse Track
A Kégresse track is a kind of rubber or canvas continuous track which uses a flexible belt rather than interlocking metal segments. It can be fitted to a conventional car or truck to turn it into a half-track, suitable for use over rough or soft ground. Conventional front wheels and steering are used, although skis may also be fitted. A snowmobile is a smaller ski-only type. Technology The Kégresse propulsion and suspension system incorporates an articulated bogie, fitted to the rear of the vehicle with a large drive wheel at one end, a large unpowered idler wheel at the other, and several small guide wheels in between, over which run a reinforced flexible belt. The belt is fitted with metal or rubber treads to grip the ground. It differs from conventional track systems by using a flexible belt rather than interlocking metal segments. Use in Russia The name comes from the system's inventor Adolphe Kégresse, who designed the original while working for Tsar Nicholas II of Russ ...

Austin Armoured Car
The Austin Armoured Car was a British armoured car produced during the First World War. The vehicle is best known for its employment by the Imperial Russian Army in the First World War and by different forces in the Russian Civil War. In addition to the British-built Austins, a few dozens of vehicles were manufactured in Russia in 1918–20. These are usually referred to as Austin-Putilov or – if fitted with a Kégresse halftrack chassis – Austin-Kégresse. Production history British Austins In August 1914, just after the beginning of the First World War, the army of the Russian Empire started to form armoured car units. Due to limited production capabilities of the country's automotive industry it was decided to order a number of vehicles abroad. A committee was sent to the United Kingdom, but failed to find an armoured car that met their requirements for overhead protection and two machine gun turrets. To meet these requirements, the Austin Motor Company designed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery Tractor In France Vosges Spring 1915
Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'', ''gun artillery'', or - a layman te ...

Linn Tractor
The Linn tractor is a heavy duty civilian half-track or crawler tractor invented by Holman Harry Linn. Approximately 2500 units were built in Morris, New York, USA from 1916 to 1952. Development Prototypes Linn was a native of Maine and in his quest for a better machine to travel rural roads with his dog and pony show equipment gave up on a six-wheel-drive design by 1907 to have Alvin Lombard, of Waterville, build a machine using the tracks off a Lombard Steam Log Hauler, and underslung gasoline engine and wheels on front. It was equipped with a ship-style cabin with living quarters and able to pull a string of wagons behind as well as supply electric lights for his circus. By 1909 this was replaced because of size with a single rear-tracked machine with standard wheeled front axle; however as Linn had become employed as a salesman, demonstrator and mechanic for Lombard a patent dispute erupted and Linn left Maine with his show. Improved traction system By 1916 Linn had develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circus
A circus is a company of performers who put on diverse entertainment shows that may include clowns, acrobats, trained animals, trapeze acts, musicians, dancers, hoopers, tightrope walkers, jugglers, magicians, ventriloquists, and unicyclists as well as other object manipulation and stunt-oriented artists. The term ''circus'' also describes the performance which has followed various formats through its 250-year modern history. Although not the inventor of the medium, Philip Astley is credited as the father of the modern circus. In 1768, Astley, a skilled equestrian, began performing exhibitions of trick horse riding in an open field called Ha'Penny Hatch on the south side of the Thames River, England. In 1770, he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between the equestrian demonstrations and thus chanced on the format which was later named a "circus". Performances developed significantly over the next fifty years, with large-scale theat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterville, Maine
Waterville is a city in Kennebec County, Maine, United States, on the west bank of the Kennebec River. The city is home to Colby College and Thomas College. As of the 2020 census the population was 15,828. Along with Augusta, Waterville is one of the principal cities of the Augusta-Waterville, ME Micropolitan Statistical Area. History The area now known as Waterville was once inhabited by the Canibas tribe of the Abenaki people. Called "Taconnet" after Chief Taconnet, the main village was located on the east bank of the Kennebec River at its confluence with the Sebasticook River at what is now Winslow. Known as "Ticonic" by English settlers, it was burned in 1692 during King William's War, after which the Canibas tribe abandoned the area. Fort Halifax was built by General John Winslow in 1754, and the last skirmish with indigenous peoples occurred on May 18, 1757. The township would be organized as Kingfield Plantation, then incorporated as Winslow in 1771. When resi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
