Jointed Boiler Locomotive
A jointed-boiler locomotive was a variant of the Mallet articulated locomotive, in which a flexible coupling was introduced midway along the length of the boiler casing, which allowed the boiler to bend laterally when the locomotive was on curved track. Six such locomotives, all of 2-6-6-2 wheel arrangement, were built for the Atchison, Topeka & Santa Fe Railroad in 1910 and 1911. The first one built, number 1157, was assembled by the AT&SF in their Topeka shops from two 2-6-2’s (numbers 1051 and 1125). All the rest were built new by Baldwin Locomotive Works. Design In a conventional Mallet, the rigid boiler is fixed to the rearmost of the two engine frames, with the front of the boiler supported on a sliding bearing over the pivoting front engine such that when the locomotive traverses a curved track, the front (smokebox) end of the boiler overhangs toward the outside of the curve. The jointed boiler, with the front half rigidly fixed to the front engine, eliminated this over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallet Locomotive
The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919). The front of the locomotive articulated on a bogie. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the rear set of driving wheels (rigidly connected to the boiler). The exhaust steam from these cylinders was fed into a low-pressure receiver and was then sent to low-pressure cylinders that powered the driving wheels on the swiveling bogie towards the front of locomotive. Compounding Steam under pressure is converted into mechanical energy more efficiently if it is used in a compound engine; in such an engine steam from a boiler is used in high-pressure (HP) cylinders and then under reduced pressure in a second set of cylinders. The lower-pressure steam occupies a larger volume and the low-pressure (LP) cylinders are larger than the high-pressure cylinders. A third stage (triple expansion) may be empl ...

Bellows
A bellows or pair of bellows is a device constructed to furnish a strong blast of air. The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. xford English Dictionary, 2nd ed: bellows/ref> It has many applications, in particular blowing on a fire to supply it with air. The term "bellows" is used by extension for a flexible bag whose volume can be changed by compression or expansion, but not used to deliver air. For example, the light-tight (but not airtight) bag allowing the distance between the lens and film of a folding photographic camera to be varied is called a bellows. Etymology "Bellows" is only used in plural. The Old English name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2-8-8-8-8-8-2
A multiplex locomotive is a steam locomotive that divides the driving force on its wheels by using multiple pairs of cylinders to drive multiple driving wheel set groups. Such a locomotive will necessarily articulated if it has more than two sets of driving wheels. There were locomotive projects with three, four, five or six sets of drive wheels. However, these locomotives were never built, except for four triplex locomotives in the United States and one quadruplex locomotive in Belgium. The names of the subgroups of multiplex locomotives is derived from the number of drive wheel sets and is composed of the numeral prefix and the word ''locomotive''. However, ''locomotive'' is often omitted if it can be inferred from the context. Duplex locomotives The terms ''duplex locomotive'' and ''Divided drive locomotive'' are used to describe locomotives with two drive wheel sets mounted in a rigid frame. The concept of the duplex locomotive originated in the early development o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-8-8-8-8-2
Under the Whyte notation for the classification of steam locomotives, a 2-8-8-8-8-2 has two leading wheels, four sets of eight driving wheels, and two trailing wheels. Because of its length, such a locomotive must be an multiplex locomotive. It is longer than a normal articulated locomotive; the fourth set of drivers is located under the tender. Other equivalent classifications are: UIC classification: 1-D-D-D-D-1 (also known as German classification and Italian classification) AAR classification: 1-D-D-D-D-1 French classification: 140+040+040+041 Turkish classification: 45+44+44+45 Swiss classification: 4/5+4/4+4/4+4/5 The equivalent UIC classification is to be refined to (1'D)DD(D1'). Usage This type of articulated locomotive was never built, the only proposal for such a locomotive came from the United States. George R. Henderson was granted US Patent 1,100,563 for a quadruplex locomotive, in June 1914. The patent was assigned to the Baldwin Locomotive Company. Baldwin ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Ember
An ember, also called a hot coal, is a hot lump of smouldering solid fuel, typically glowing, composed of greatly heated wood, coal, or other carbon-based material. Embers (hot coals) can exist within, remain after, or sometimes precede, a fire. Embers are, in some cases, as hot as the fire which created them. They radiate a substantial amount of heat long after the fire has been extinguished, and if not taken care of properly can rekindle a fire that is thought to be completely extinguished and can pose a fire hazard. In order to avoid the danger of accidentally spreading a fire, many campers pour water on the embers or cover them in dirt. Alternatively, embers can be used to relight a fire after it has gone out without the need to rebuild the fire – in a conventional fireplace, a fire can easily be relit up to 12 hours after it goes out, provided that there is enough space for air to circulate between the embers and the introduced fuel. They are often used for cooking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...
