Steamroller
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] |
Aveling And Porter
Aveling and Porter was a British agricultural engine and steamroller (road roller) manufacturer. Thomas Aveling and Richard Thomas Porter entered into partnership in 1862, and developed a steam engine three years later in 1865. By the early 1900s, the company had become the largest manufacturer of steamrollers (road rollers) in the world. The company used a rampant horse as its logo derived from the White Horse of Kent. Partners Thomas Aveling Thomas Aveling was born 11 September 1824 at Elm, Cambridgeshire. His mother was widowed while Aveling was still young and the family settled in Hoo (Rochester, Kent). His mother remarried to the Rev. John D'Urban of Hoo. Thomas' stepfather brought him up with "a Bible in one hand and a birch rod in the other". Aveling was apprenticed to Edward Lake, a farmer, of Hoo. Aveling married Edward's niece, Sarah Lake (daughter of Robert Lake of Milton-Chapel near Canterbury) and in 1850 took a farm at Ruckinge on Romney Marsh. In 18 ...

Traction Engine
A traction engine is a steam engine, steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin ''tractus'', meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway steam locomotive, locomotives – that is, steam engines that run on rails. Traction engines tend to be large, robust and powerful, but also heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative Prime mover (tractor unit), prime mover was the draught horse. They became popular in industrialised countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed. Production continued well into the early part of the 20th century, when competition from internal combustion engine-powered ...

Road Roller
A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion. History The first road rollers were horse-drawn, and were probably borrowed farm implements'' (see Roller)''. Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century. The first such vehicles were steam rollers. Single-cylinder steam rollers were generally used for base compaction and run with high engine revs with low gearing to promote bounce and vibration from the crankshaft through to the rolls in much the same way as a vibrating roller. The double cylinder or compound steam rollers became popular from around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robey & Co
Robey and Co. was an engineering company based in Lincoln, England which can be traced back to at least 1849. In 1854 Watkinson and Robey ''Engineers and Millwrights'' were manufacturing Portable Engines and machinery of every description in Rumbold Street, Lincoln. They were joined by George Lamb Scott, but in 1855 Watkinson, who had previously worked for Clayton & Shuttleworth of Lincoln, left the company. The business then became Robey and Scott and moved their premises by 1856 to Canwick Road, Lincoln. Another partner, Thomas Gamble, joined the firm and Scott resigned in September 1856 to found his own manufacturing company in Manchester. The company then became Gamble & Robey, but by 1868 was known as Robey & Co Ltd. Robert Robey died in 1876 and the firm continued as a partnership led by John Richardson. In 1893 Robey & Co became a limited company. By 1913 Robeys were makers of steam motor wagons, tractors and ploughs and in the First World War manufactured aircraft. T ...

Steam Wagon
A steam wagon (or steam lorry, steam waggon or steamtruck) is a steam-powered truck for carrying freight. It was the earliest form of lorry (truck) and came in two basic forms: ''overtype'' and ''undertype'', the distinction being the position of the engine relative to the boiler. Manufacturers tended to concentrate on one form or the other. Steam wagons were a widespread form of powered road traction for commercial haulage in the early part of the twentieth century, although they were a largely British phenomenon, with few manufacturers outside Great Britain. Competition from internal-combustion-powered vehicles and adverse legislation meant that few remained in commercial use beyond the Second World War. Although the majority of steam wagons have been scrapped, a significant number have been preserved in working order and may be seen in operation at steam fairs, particularly in the UK. Design features The steam wagon came in two basic forms. The ''overtype'' designs looked li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol Boiler
A pistol boiler is a design of steam boiler used in light steam tractors and overtype steam wagons. It is noted for the unusual shape of the firebox, a circular design intended to be self-supporting without the use of firebox stays. The name "pistol boiler" derives from the smooth curve of the outer firebox flowing into the boiler barrel and a supposed resemblance to the stock of an early 19th-century pistol. Need for a self-supporting firebox The locomotive boiler had become well established since Stephenson's day; although the cost and complexity of its firebox remained a drawback, particularly for small boilers. If the top crown sheet of the inner firebox was made flat, so as to maintain a constant water depth above it, this required complex and expensive girder stays to support it. These stays were also a safety-critical part of the boiler, and many past boiler explosions had been caused by their failure. This was especially so for boilers that were likely to be used at ...

Tarmacadam
Tarmacadam is a road surfacing material made by combining crushed stone, tar, and sand, patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 1800s. The terms "tarmacadam" and tarmac are also used for a variety of other materials, including tar- grouted macadam, bituminous surface treatments and modern asphalt concrete. Origins Macadam roads pioneered by British engineer John Loudon McAdam in the 1820s are prone to rutting and generating dust. Methods to stabilise macadam surfaces with tar date back to at least 1834 when John Henry Cassell, operating from ''Cassell's Patent Lava Stone Works'' in Millwall, England, patented "lava stone". This method involved spreading tar on the subgrade, placing a typical macadam layer, and finally sealing the macadam with a mixture of tar and sand. Tar-grouted macadam was in use well before ...

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 ...

Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1 Motorway
The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; the first motorway in the country was the Preston By-pass, which later became part of the M6. The motorway is long and was constructed in four phases. Most of the motorway was opened between 1959 and 1968. The southern end was extended in 1977 and the northern end was extended in 1999. History There had been plans before the Second World War for a motorway network in the United Kingdom. Lord Montagu formed a company to build a 'motorway like road' from London to Birmingham in 1923, but it was a further 26 years before the Special Roads Act 1949 was passed, which allowed for the construction of roads limited to specific vehicle classifications, and in the 1950s, the country's first motorways were given the government go-ahead. The first section of motorway was the Preston Bypass in Lancashire, now par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Show
The Royal Show, also known as the Royal Agricultural Show, was an annual agricultural show/fair held by the Royal Agricultural Society of England every year from 1839 to 2009. The event encompassed all aspects of farming, food and rural life - from the best of British livestock to the latest business and technological innovations in the farming industry. Over 1,000 stands, world-class livestock and equine classes attracted visitors from over 100 countries. The Royal Show gave the name; Park Royal to the part of west London which once hosted the show. The Royal Agricultural Society of England had planned to make the site a permanent home for the Royal Show. It was not a success and the Society sold the land in 1907. Indirectly, the show also provided the name of the Kansas City Royals baseball team, which was named for that city's American Royal show, named after the Royal Show. History On the road from 1839 to 1902 Between 1839 and 1902 the Royal Show was held at various lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
