Thomas Powell (steamboat)
''Thomas Powell'' was a fast and popular steamboat built in Manhattan, New York City in 1846 for service on the Hudson River. She ran between New York City and various Hudson River destinations during her career, including Newburgh, Piermont, Poughkeepsie, Rondout, Catskill, and finally as a nightboat to Troy. She also ran on the Delaware River for some years in the 1850s, and during the American Civil War served as a Union Army dispatch boat. ''Thomas Powell'' was considered one of the fastest, if not the fastest, of the Hudson River steamers of her time, capable of speeds in excess of . Her speed, excellent accommodations and good management made her a favorite with the traveling public, and consequently, she retained her original name to the end of her career. Her last known trip was made in 1879 and she was scrapped in 1881. Construction and design In 1846, Thomas Powell, a prominent businessman of Newburgh, New York, and his son-in-law Homer Ramsdell, ordered a new st ...

Appomattox River
The Appomattox River is a tributary of the James River, approximately long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 1, 2011 in central and eastern Virginia in the United States, named for the Appomattocs Indian tribe who lived along its lower banks in the 17th century. It drains a cotton and tobacco-growing region of the Piedmont and coastal plain southwest of Richmond. The English colonists in Virginia at first tried to rename the Appomattox as the "Bristoll River", however this name did not catch on, while the native one did. There are numerous historical spelling variants, such as Apamatuck, Apamutiky, Appamattuck, Appomattake, and Apumetecs, among others. Course The Appomattox River rises in the middle of a field near State Route 656 (Horseshoe Road) in the Piedmont of northeastern Appomattox County, approximately northeast of the town of Appomattox. It flows generally southeast through the Appomat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catskill, New York
Catskill is a town in the southeastern section of Greene County, New York, United States. The population was 11,298 at the 2020 census, the largest town in the county. The western part of the town is in the Catskill Park. The town contains a village, also called Catskill. The village of Catskill has a well-defined Main Street. There is a public boat launch on the Hudson River called Dutchman's Landing. History The area of the town was purchased from the indigenous peoples in 1678, and the first settler was Derrick Teunis van Vechten, who built a house here in 1680. The town was established on March 7, 1788, as part of Albany County. When Greene County was formed on March 25, 1800, Catskill became part of the new county. The town was increased by an addition from the town of Woodstock in 1800, but was later decreased upon the formation of the towns of Cairo (1803) and Athens (1815). Catskill is the location of the story "Rip Van Winkle" by Washington Irving. On July 23, 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morgan Iron Works
The Morgan Iron Works was a 19th-century manufacturing plant for marine steam engines located in New York City, United States. Founded as T. F. Secor & Co. in 1838, the plant was later taken over and renamed by one of its original investors, Charles Morgan. The Morgan Iron Works remained a leading manufacturer of marine engines throughout the 19th century, producing at least 144 in the period between 1838 and 1867, including 23 for U.S. Navy vessels during the American Civil War. The Morgan Iron Works was sold to shipbuilder John Roach in 1867, who integrated its operations with his shipyard in Chester, Pennsylvania. The Works continued to operate as both an engine plant and a ship repair facility in the hands of Roach and his son John Baker Roach until 1907, when the Roach family finally retired from the shipbuilding business. Secor & Co., 1838–1850 The marine engine works of T. F. Secor and Co. was originally established in New York City, at Ninth Street, East River ...

Anthracite
Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 97%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. The Coal Region of northeastern Pen ...

Cutoff (steam Engine)
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine. Once the valve has closed, steam trapped in the cylinder expands adiabatically. The steam pressure drops as it expands. A late cutoff delivers full steam pressure to move the piston through its entire stroke, for maximum start-up forces. But, since there will still be unexploited pressure in the cylinder at the end of the stroke, this is achieved at the expense of engine efficiency. In this situation the steam will still have considerable pressure remaining when it is exhausted resulting in the characteristic “chuff chuff” sound of a steam engine. An early cutoff has greater thermodynamic efficiency but results in a lower Mean effective pressure so less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds (rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * Engine displacement Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the ... References {{Steam engine configurations Engine technology ...

Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802.

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bust (sculpture)
A bust is a sculpted or cast representation of the upper part of the human figure, depicting a person's head and neck, and a variable portion of the chest and shoulders. The piece is normally supported by a plinth. The bust is generally a portrait intended to record the appearance of an individual, but may sometimes represent a type. They may be of any medium used for sculpture, such as marble, bronze, terracotta, plaster, wax or wood. As a format that allows the most distinctive characteristics of an individual to be depicted with much less work, and therefore expense, and occupying far less space than a full-length statue, the bust has been since ancient times a popular style of life-size portrait sculpture. It can also be executed in weaker materials, such as terracotta. A sculpture that only includes the head, perhaps with the neck, is more strictly called a "head", but this distinction is not always observed. Display often involves an integral or separate display stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
