Living Van
A living van is a portable caravan, used by the itinerant crew of a traction engine. Living vans developed from the earlier shepherd's wagons, used to provide portable accommodation following a flock as they were moved between pastures. 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 portable engines: movable steam engines that were horse-drawn to move them, unlit, between farms. 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 often a boy. Other agric ...

Oilcloth
Oilcloth, also known as enameled cloth or American cloth, is close-woven cotton duck or linen cloth with a coating of boiled linseed oil to make it waterproof. Manufacture Boiled linseed oil was prepared by a long boiling of linseed oil with metal salts, originally lead dross. The modern oil is less toxic, but also less suitable for making oilcloth. Re-enactors may boil their own oil in the search for a correctly coloured oilcloth. Oilcloth used for weatherproofing may have used a mixture of lead and manganese salts, the sienna and umber pigments, to give a more humidity-resistant cure. The fabric was first stretched on a tenter frame and sized with animal gelatine. The oil was then applied and allowed to cure between coats. As the cure relies on oxidation by the air, thin coats and long cure times between are required. Overlaps between sheets of fresh oilcloth would amalgamate naturally when pressed together. This tendency also led to the cloth sticking together when folded. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

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 propulsion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatic Tyre
Pneumatics (from Greek ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. Gases used in pneumatic systems Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Factory-plumbed ...

Clerestory
In architecture, a clerestory ( ; , also clearstory, clearstorey, or overstorey) is a high section of wall that contains windows above eye level. Its purpose is to admit light, fresh air, or both. Historically, ''clerestory'' denoted an upper level of a Roman basilica or of the nave of a Romanesque or Gothic church, the walls of which rise above the rooflines of the lower aisles and are pierced with windows. Similar structures have been used in transportation vehicles to provide additional lighting, ventilation, or headroom. History Ancient world The technology of the clerestory appears to originate in the temples of ancient Egypt. The term "clerestory" is applicable to 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. Clerestory appeared in Egypt at least as early as the Amarna period. In the Minoan palaces of Crete such as Knossos, by contrast, lightwel ...

John Fowler & Co
John Fowler & Co Engineers of Leathley Road, Hunslet, Leeds, West Yorkshire, England produced traction engines and ploughing implements and equipment, as well as railway equipment. Fowler also produced the Track Marshall tractor which was a tracked version of the Field Marshall. British Railways Engineering Department locomotives ED1 to ED7 were built by Fowler History John Fowler was an agricultural engineer and inventor who was born in Wiltshire in 1826. He worked on the mechanisation of agriculture and was based in Leeds. He is credited with the invention of steam-driven ploughing engines. He died 4 December 1864, following a hunting accident. After his death, John Fowler & Co., was then continued by Robert Fowler and Robert Eddison. In 1886 the limited company of John Fowler & Co., (Leeds) Ltd., was formed. It merged with Marshall, Sons & Co., Ltd., of Gainsborough in 1947 to form Marshall-Fowler Ltd. Although not well known for them, Fowler also built a sma ...

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 or shaper of wood) as in shipwright and arkwright. This occupational name became the English surname ''Wright''. It also appears in surnames like ''Cartwright'' and ''Wainwright''. It corresponds with skilful metal workers being called ''Smith.'' These tradesmen made wheels for carts (cartwheels), wagons (wains), traps and coaches and the belt drives of steam powered machinery. They also made the wheels, and often the frames, for spinning wheels for home use. First constructing the hub (called the nave), the spokes and the rim segments called felloes, (pronounced fell low), 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. S ...

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, 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 for artillery carri ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and 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 cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...
