Luttermöller Axle
A Luttermöller axle is an unusual steam locomotive component. Steam locomotives with several axles or Wheelset (rail transport), wheelsets connected to one another by coupling rods are not able to negotiate tight curves well. In order to assist such locomotives, the manager of the Orenstein & Koppel factory in Berlin, Dr. Luttermöller, built the axle system named after him. Overview With this system, the outermost of several sets of successive driving wheel sets are not connected by coupling rods to crankshaft journals on the outside of the wheels, but by Gear, cogwheels located in the centre of the axles. The axles are housed in the locomotive frame such that they are able to move at right angles to the axis of the rails to a certain degree, likewise the cogwheels are able to slide relative to one another. In this way curves can be negotiated with less friction being generated. Use Germany For the Hamburg Harbour railway with its tight curves, the ten-coupled steam locomotives ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Narrow Gauge
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Motion Device
A lateral motion device is a mechanism used in some railroad locomotives which permits the axles to move sideways relative to the frame. The device facilitates cornering. Purpose Prior to the introduction of the lateral motion device, the coupled driving wheels on steam locomotives (often simply called "drivers") were held in a straight line by the locomotive's frame. The flanges of the drivers were spaced a bit closer than the rail gauge, and they could still fit between the rails when tracking through a mild curve. At some degree of curvature, though, the flanges on the center driver would begin to bind in the curve. The closer the front and rear drivers were, the smaller the radius of curve that the locomotive could negotiate. One solution was to make the center driver(s) "blind," i.e. without flanges on the tires. The other solution was to allow at least one of the axles (often the front driver) to move laterally relative to the frame, and such designs incorporated various devi ...

Krauss-Helmholtz Bogie
A Krauss-Helmholtz bogie (''Krauss-Helmholtz-Lenkgestell'') is a mechanism used on steam locomotives and some electric locomotives to improve curve running. Operation The bogie comprises a carrying axle connected to a coupled axle via a shaft or lever. In straight running, any radial movement of the carrying axle results in a sideways movement of the coupled axle in the opposite direction. However, the carrying axle is centred by means of two heavy duty springs just behind it. In addition the pivot pin may be allowed to move sideways, but again is held centrally by heavy springs. When travelling round a curve, the carrying axle swings to one side causing the coupled axle to move sideways in the opposite direction. In this way radial forces during curve running are more or less evened out on both axles, so that riding qualities similar to those of a normal bogie are achieved and wear and tear reduced on wheel flanges and rails. The bogie is a type of pony truck and was name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klose-Lenkwerk
Adolf Klose (21 May 1844 – 2 September 1923) was the chief engineer of the Royal Württemberg State Railways in southern Germany from June 1885 to 1896. Klose was born in Bernstadt auf dem Eigen, in Saxony. Before his taking up his post in Stuttgart he had been the technical inspector of the United Swiss Railways (''Vereinigten Schweizerbahnen''). After a period of depending on Prussian prototypes between 1865 and 1885, a new engineering direction followed under Klose's time in office. It was stamped by numerous home-grown ideas and discoveries. In particular he promoted the introduction of compound working for steam locomotives in Württemberg. The patented Klose steering (''Klose-Lenkwerk'') carries his name. This was a multipartite and complex device for steam locomotives, which controlled the radial setting of leading and trailing wheelsets in order to improve curve running. Unfortunately, its costly maintenance and tendency to develop faults meant that his invention had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klien-Lindner Axle
The Klien-Lindner axle (German: ''Klien-Lindner-Hohlachse'') is a special type of hollow driving axle on steam locomotives that enable better curve running due to its ability to slide transversely. It was developed by the German engineers, Ewald Klien and Heinrich Lindner, of the Royal Saxon State Railways (''Königlich Sächsische Staatseisenbahnen''). Design features The Klien-Lindner axle uses a double, or hollow, axle, one inside the other. It has a hollow axle (''Hohlachse'') on the outside, connected at its centre by a Cardan joint to a fixed driving axle running through it. The Cardan joint comprises two spherical elements that are interlinked - a solid one on the fixed axle and a hollow one on the outer hollow axle, each oriented at 90° to the other that transfer the driving forces from the rigid axle to the hollow one. The hollow spheroid acts as a sort of link motion. In this way the hollow axle can be turned by the fixed axle. In addition, the connecting link is shape ...

Sir Arthur Heywood, 3rd Baronet
Sir Arthur Percival Heywood, 3rd Baronet (25 December 1849 – 19 April 1916) is best known today as the innovator of the fifteen inch minimum gauge railway, for estate use. Early life He was the eldest son of Sir Thomas Percival Heywood and grew up in the family home of Dove Leys at Denstone in Staffordshire. Dove Leys looked over the valley where the North Staffordshire Railway from Rocester to Ashbourne ran. The family travelled by train to their relatives in Manchester and on holiday to Inveran in the Highland region of Scotland. Heywood developed a passion for the railway from an early age. He assisted his father in his hobby of ornamental metalwork, with a Holtzapffel lathe, and in his late teenage, built a 4 in gauge model railway with a steam locomotive. Wanting something on which his younger siblings could ride, he went on to build a 9 in gauge locomotive and train, which gave him the experience for his later ventures. Initially schooled at Eton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gölsdorf Axle
The Gölsdorf axle system is used on railway Gölsdorf locomotives to achieve quiet running and low wear-and-tear when negotiating curves. The axle system comprises a combination of fixed axles and axles that can slide transversely, all within a single, rigid locomotive frame. The system was invented by a young Austrian locomotive builder, Karl Gölsdorf, around the end of the 19th century. The first locomotive to use this principle entered service in 1897. Overview In the early days of the railway, locomotives were built with more and more axles in order the meet the increasingly heavy loads of goods trains. In order not to overstress the tracks, axle loads were often restricted, initially to 16 tonnes, occasionally to 18 tonnes and later usually to 20 tonnes. A ten-coupled locomotive had to weigh no more than 100 tonnes plus whatever tonnage the leading and trailing wheels could support. The heavier a locomotive is, the more surface pressure it places on the wheels and the more it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kent
Kent is a county in South East England and one of the home counties. It borders Greater London to the north-west, Surrey to the west and East Sussex to the south-west, and Essex to the north across the estuary of the River Thames; it faces the French department of Pas-de-Calais across the Strait of Dover. The county town is Maidstone. It is the fifth most populous county in England, the most populous non-Metropolitan county and the most populous of the home counties. Kent was one of the first British territories to be settled by Germanic tribes, most notably the Jutes, following the withdrawal of the Romans. Canterbury Cathedral in Kent, the oldest cathedral in England, has been the seat of the Archbishops of Canterbury since the conversion of England to Christianity that began in the 6th century with Saint Augustine. Rochester Cathedral in Medway is England's second-oldest cathedral. Located between London and the Strait of Dover, which separates England from mainla ...

Salta Province
Salta () is a province of Argentina, located in the northwest of the country. Neighboring provinces are from the east clockwise Formosa, Chaco, Santiago del Estero, Tucumán and Catamarca. It also surrounds Jujuy. To the north it borders Bolivia and Paraguay and to the west lies Chile. History Before the Spanish conquest, numerous native peoples (now called Diaguitas and Calchaquíes) lived in the valleys of what is now Salta Province; they formed many different tribes, the Quilmes and Humahuacas among them, which all shared the Cacán language. The Atacamas lived in the Puna, and the Wichís (Matacos), in the Chaco region. The first conquistador to venture into the area was Diego de Almagro in 1535; he was followed by Diego de Rojas. Hernando de Lerma founded San Felipe de Lerma in 1582, following orders of the viceroy Francisco de Toledo, Count of Oropesa; the name of the city was soon changed to "San Felipe de Salta". By 1650, the city had around five hundred inhabitan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (Indonesia)
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java.
