Lucy Walker Steamboat Disaster
The ''Lucy Walker'' steamboat disaster was an 1844 steamboat accident caused by the explosion of the boilers of the steamboat ''Lucy Walker'' near New Albany, Indiana, on the Ohio River. The explosion occurred on the afternoon of Wednesday, October 23, 1844, when the steamer's three boilers exploded, set the vessel on fire, and sank it. It was one of a number of similar accidents of early 19th-century riverine transportation that led to important federal legislation and safety regulations. The vessel's owner was a Native American; her crew were African-American slaves, and her passengers represented a cross-section of frontier travelers. Circumstances leading up to the disaster The ''Lucy Walker'' was an average vessel of her time: long with a beam of and a draft of . She displaced 183 tons.Bureau of Marine Inspection and Navigation (Cincinnati Office, 1843–44), "Vessel Enrollment Documents."

Lucy Walker Explosion
Lucy is an English feminine given name derived from the Latin masculine given name Lucius with the meaning ''as of light'' (''born at dawn or daylight'', maybe also ''shiny'', or ''of light complexion''). Alternative spellings are Luci, Luce, Lucie, Lucia, and Luzia. The English Lucy surname is taken from the Norman language that was Latin-based and derives from place names in Normandy based on Latin male personal name Lucius. It was transmitted to England after the Norman Conquest in the 11th century (see also De Lucy).

Internal Improvements
Internal improvements is the term used historically in the United States for public works from the end of the American Revolution through much of the 19th century, mainly for the creation of a transportation infrastructure: roads, turnpikes, canals, harbors and navigation improvements.Review by Tom Review of John Lauritz Larson's Internal Improvement: National Public Works and the Promise of Popular Government in the Early United States', University of North Carolina Press, 2001. . This older term carries the connotation of a political movement that called for the exercise of public spirit as well as the search for immediate economic gain. Improving the country's natural advantages by developments in transportation was, in the eyes of George Washington and many others, a duty incumbent both on governments and on individual citizens. Background While the need for inland transportation improvements was universally recognized, there were great differences over the questions of how the ...

Andrew Jackson
Andrew Jackson (March 15, 1767 – June 8, 1845) was an American lawyer, planter, general, and statesman who served as the seventh president of the United States from 1829 to 1837. Before being elected to the presidency, he gained fame as a general in the United States Army and served in both houses of the U.S. Congress. Although often praised as an advocate for ordinary Americans and for his work in preserving the union of states, Jackson has also been criticized for his racial policies, particularly his treatment of Native Americans. Jackson was born in the colonial Carolinas before the American Revolutionary War. He became a frontier lawyer and married Rachel Donelson Robards. He served briefly in the United States House of Representatives and the United States Senate, representing Tennessee. After resigning, he served as a justice on the Tennessee Supreme Court from 1798 until 1804. Jackson purchased a property later known as the Hermitage, becoming a wealthy plan ...

Glossary Of Boiler Terminology
Boilers for generating steam or hot water have been designed in countless shapes, sizes and configurations. An extensive terminology has evolved to describe their common features. This glossary provides definitions for these terms. Terms which relate solely to boilers used for space heating or generating hot water are identified by (HVAC). A-B ; : A container beneath the furnace, catching ash and clinker that falls through the firebars. This may be made of brickwork for a stationary boiler, or steel sheet for a locomotive. Ashpans are often the location of the damper. They may also be shaped into hoppers, for easy cleaning during disposal. ; Blastpipe: Part of the exhaust system that discharges exhaust steam from the cylinders into the smokebox beneath the chimney in order to increase the draught through the fire. ; Blow-down: Periodic venting of water from the boiler. This water contains the most concentrated precursors for sludge build-up, so by venting it whilst still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Valve
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk. Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early boilers operating without them were prone to explosion unless carefully operated. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manu ...

Feedwater Pump
A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type. Construction and operation Feedwater pumps range in size up to many kilowatts and the electric motor is usually separated from the pump body by some form of mechanical coupling. Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of a centrifugal pump. Another common form of feedwater pump runs constantly and is provided with a minimum flow device to stop overpressuring the ...

Ad Hoc
Ad hoc is a Latin phrase meaning literally 'to this'. In English, it typically signifies a solution for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances. (Compare with ''a priori''.) Common examples are ad hoc committees and commissions created at the national or international level for a specific task. In other fields, the term could refer to, for example, a military unit created under special circumstances (see '' task force''), a handcrafted network protocol (e.g., ad hoc network), a temporary banding together of geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation. Ad hoc can also be an adjective describing the temporary, provisional, or improvised methods to deal with a particular problem, the tendency of which has given rise to the noun ''adhocism''. Styling Style guides disagree on whether Latin phrases like ad hoc should be italicized. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Sultana
''Sultana'' was a commercial side-wheel steamboat which exploded and sank on the Mississippi River on April 27, 1865, killing 1,169 people in what remains the worst maritime disaster in United States history. Constructed of wood in 1863 by the John Litherbury Boatyard in Cincinnati, Ohio, ''Sultana'' was intended for the lower Mississippi cotton trade. The steamer registered 1,719 tons and normally carried a crew of 85. For two years, she ran a regular route between St. Louis and New Orleans and was frequently commissioned to carry troops during the American Civil War. Although designed with a capacity of only 376 passengers, she was carrying 2,130 when three of the boat's four boilers exploded and caused it to sink near Memphis, Tennessee. The disaster was overshadowed in the press by events surrounding the end of the Civil War, including the killing of President Abraham Lincoln's assassin John Wilkes Booth just the day before. No one was ever held accountable for the tragedy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snagboat
A snagboat is a river boat, resembling a barge with superstructure for crew accommodations, and deck-mounted cranes and hoists for removing snags and other obstructions from rivers and other shallow waterways. USA During the American Civil War, when much of the naval fighting was done on rivers and their tributaries, numerous snagboats were in operation. , for example, was a commercial snagboat quickly converted by the Union Army to a river gunboat when the American Civil War broke out. Snagboats of the USA Bear was a wooden-hulled, stern-wheel steamship that served as a snagboat for the United States Army Corps of Engineers. Seizer was a wooden-hulled, stern-wheel steamship that served as the first snagboat for the United States Army Corps of Engineers on the Sacramento River. '' W. T. Preston'' is a specialized sternwheeler that operated as a snagboat, removing log jams and natural debris that prevented river navigation on several Puget Sound-area rivers. She is now t ...
