Living Van
A living van is a portable Travel trailer, caravan for temporary use of traveling work crews, especially of Traction engine, early steam engines. Living vans developed from the earlier shepherd's wagons, used to provide portable accommodation following a flock as they were moved between pastures. Historic overview Traction engines in the Victorian period represented an expensive capital investment in the latest agricultural technology of the period. Many were owned by contractors who would move them from farm to farm for hire, as required. Typical work included threshing after harvest time. A rake of engine, threshing machine, a living van and often a water wagon would travel from farm to farm as needed, stopping at each for a few days. The first engines, from around 1840, were horse-drawn portable engines. From the 1860s the ''locomotive'' traction engine appeared, now capable of moving under its own power. The engine's crew would include a driver, a steersman, and ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Matchboard
Matchboard by definition is "a board with a groove cut along one edge and a tongue along the other so as to fit snugly with the edges of similarly cut boards." Matchboarding can be used both internally and externally, and can be layered in many different styles including: square edge, feather edge, ship lap and tongue and groove. Matchboard was most popular in the late Victorian period, when woodworking machinery had developed that could cut the edge joints quickly and cheaply. In the 1930s, further developments in glues and veneer-cutting machinery made plywood affordable. This also gave a cleanly smooth-surfaced Modernist look that suited the taste for new styles. Matchboard then became much less popular. In the 1970s there was a resurgence of interest in the style as a retro Retro style is imitative or consciously derivative of lifestyles, trends, or art forms from the past, including in music, modes, fashions, or attitudes. It has been argued that there is a nostalgia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and Tarmacadam, tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface road surface, roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the nineteenth century. It consists of Construction aggregate, mineral aggregate Binder (material), bound together with bitumen (a substance also independently known as asphalt, Pitch (resin), pitch, or tar), laid in layers, and compacted. The American English terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Roller
A steamroller (or steam roller) is a form of road roller – a type of heavy construction machinery used for leveling surfaces, such as roads or airfields – that is powered by a steam engine. The leveling/flattening action is achieved through a combination of the size and weight of the vehicle and the ''rolls'': the smooth wheels and the large cylinder or drum fitted in place of treaded road wheels. The majority of steam rollers are outwardly similar to traction engines as many traction engine manufacturers later produced rollers based on their existing designs, and the patents owned by certain roller manufacturers tended to influence the general arrangements used by others. The key difference between the two vehicles is that on a roller the main roll replaces the front wheels and axle that would be fitted to a traction engine, and the driving wheels are smooth-tired. The word ''steamroller'' frequently refers to road rollers in general, regardless of the method of propulsio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatic Tyre
A tire (North American English) or tyre (Commonwealth English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, tires were ...

Clerestory
A clerestory ( ; , also clearstory, clearstorey, or overstorey; from Old French ''cler estor'') is a high section of wall that contains windows above eye-level. Its purpose is to admit light, fresh air, or both. Historically, a ''clerestory'' formed an upper level of a Roman basilica or of the nave of a Romanesque architecture, Romanesque or Gothic architecture, Gothic church (building), church, the walls of which rise above the rooflines of the lower aisles and which are pierced with windows. In addition to architecture, #Transportation, clerestories have been used in transportation vehicles such as buses and trains to provide additional lighting, ventilation, or headroom. History Ancient world Clerestories appear to originate in Egyptian temples, where the lighting of the hall of columns was obtained over the stone roofs of the adjoining aisles, through gaps left in the vertical slabs of stone. They appeared in Egypt at least as early as the Amarna Period. Minoan palaces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cart Wheel
A wheelwright is a craftsman who builds or repairs wooden wheels. The word is the combination of "wheel" and the word "wright" (which comes from the Old English word "''wryhta''", meaning a worker - as also in shipwright and arkwright). This occupational name became the English surname ''Wright'', and also appears in surnames like ''Cartwright'' and ''Wainwright''. These tradesmen made wheels for carts (cartwheels), wagons (wains), traps and coaches. They also made the wheels, and often the frames, for spinning wheels, and the belt drives of steam powered machinery. First constructing the hub (called the nave), the spokes and the rim segments called felloes, and assembling them all into a unit working from the center of the wheel outwards. Most wheels were made from wood, but other materials have been used, such as bone and horn, for decorative or other purposes. Some earlier construction for wheels such as those used in early chariots were bound by rawhide that would be appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery Wheel
The artillery wheel was a nineteenth-century and early-twentieth-century style of wagon, gun carriage, and automobile wheel. Rather than having its spokes mortised into a wooden nave (hub), it has them fitted together in a keystone fashion with miter joints, bolted into a two-piece metal nave. Its tyre is shrunk onto the rim in the usual way, but it may also be bolted on for security. The design evolved over the nineteenth and early twentieth century, and was ultimately imitated in drawn steel for auto wheels, which sometimes show little immediate resemblance to most of their design ancestry. Wood artillery wheels Wheels with wood spokes fitted together in a keystone fashion with miter joints, bolted into a two-piece metal Nave (wheel hub), nave, were called "wedge wheels" by Walter Hancock who described them in 1834, as he used them on his steam-powered road vehicles. In response to Hancock's description, John Robison said he had wheels of the same description built in 1811 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Chock
Wheel chocks (or chocks) are wedges of sturdy material placed closely against a vehicle's wheels to prevent accidental movement. Chocks are placed for safety in addition to setting the brakes. The bottom surface is sometimes coated in rubber to enhance grip with the ground. For ease of removal, a rope may be tied to the chock or a set of two chocks. One edge of the wedge has a concave profile to contour to the wheel and increase the force necessary to overrun the chock. Most commonly, chocks are seen on aircraft and train cars. Automobiles usually have parking brakes on the rear wheels. If the rear axle is jacked off the ground with only the parking brake set, the vehicle may roll on the front wheels and fall. Chocking the front wheels prevents this mishap. Motorcycle and bicycle chocks are bifurcated and fit around the wheel, supporting the bike and preventing its movement. The mining industry uses wheel chocks to protect lubrication trucks and heavy maintenance vehicles fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
