Steamboats
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet in the steam-filled cylinder, which condensed the steam, creating a vacuum, which in turn caus ...

Oliver Evans
Oliver Evans (September 13, 1755 – April 15, 1819) was an American inventor, engineer and businessman born in rural Delaware and later rooted commercially in Philadelphia. He was one of the first Americans building steam engines and an advocate of high pressure steam (vs. low pressure steam). A pioneer in the fields of automation, materials handling and steam power, Evans was one of the most prolific and influential inventors in the early years of the United States. He left behind a long series of accomplishments, most notably designing and building the first fully automated industrial process, the first high-pressure steam engine, and the first (albeit crude) amphibious vehicle and American automobile. Born in Newport, Delaware, Evans received little formal education and in his mid-teens was apprenticed to a wheelwright. Going into business with his brothers, he worked for over a decade designing, building and perfecting an automated mill with devices such as bucket chains ...

Riverboat
A riverboat is a watercraft designed for inland navigation on lakes, rivers, and artificial waterways. They are generally equipped and outfitted as work boats in one of the carrying trades, for freight or people transport, including luxury units constructed for entertainment enterprises, such as lake or harbour tour boats. As larger water craft, virtually all riverboats are especially designed and constructed, or alternatively, constructed with special-purpose features that optimize them as riverine or lake service craft, for instance, dredgers, survey boats, fisheries management craft, fireboats and law enforcement patrol craft. Design differences Riverboats are usually less sturdy than ships built for the open seas, with limited navigational and rescue equipment, as they do not have to withstand the high winds or large waves characteristic to large lakes, seas or oceans. They can thus be built from light composite materials. They are limited in size by width and depth of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyroscaphe
''Pyroscaphe'' was an early experimental steamship built by Marquis de Jouffroy d'Abbans in 1783. The first demonstration took place on 15 July 1783 on the river Saône in France. After the first demonstration, it was said that the hull had opened up and the boiler was letting out steam, faults common in early steamboats. In this case, it seems to have been easily repaired as the boat was said to have made several trips up and down the river. A month later, on 19 August, the boat carried several passengers who signed a witness protocol for a successful journey.https://www.exploralyon.fr/?p=548 The ''Pyroscaphe'' was propelled by a double-acting steam machine and sidewheels, and was therefore a paddle steamer A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water.

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.

Thomas Newcomen
Thomas Newcomen (; February 1664 – 5 August 1729) was an English inventor who created the atmospheric engine, the first practical fuel-burning engine in 1712. He was an ironmonger by trade and a Baptist lay preacher by calling. He was born in Dartmouth, in Devon, England, to a merchant family and baptised at St. Saviour's Church on 28 February 1664. In those days flooding in coal and tin mines was a major problem. Newcomen was soon engaged in trying to improve ways to pump out the water from such mines. His ironmonger's business specialised in designing, manufacturing and selling tools for the mining industry. Religious life Thomas Newcomen was a lay preacher and a teaching elder in the local Baptist church. After 1710 he became the pastor of a local group of Baptists. His father had been one of a group who brought the well-known Puritan John Flavel to Dartmouth. Later one of Newcomen's business contacts in London, Edward Wallin, was another Baptist minister who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Henry (delegate)
William Henry (May 19, 1729 – December 15, 1786) was an American gunsmith, engineer, politician, and merchant from Lancaster, Pennsylvania, and a delegate for Pennsylvania to the Continental Congress in 1784, 1785, and 1786. Henry is also noted for his contributions in development of the first steam engines. Biography William Henry was born near Downingtown, Pennsylvania to a family of Scots-Irish extraction. Prior to his service in the Continental Congress, Henry was a gunsmith and provided rifles to the British during the French and Indian War: Henry himself, serving as armorer, accompanied troops on John Forbes's successful mission to retake Fort Duquesne in 1758. By 1760, according to Scott Paul Gordon, Henry had largely abandoned his occupation of gunsmith and had become a successful ironmonger and merchant in Lancaster. Henry later served in many positions of public responsibility, including Assistant Commissary General to the Continental Army for the district of Lancas ...

Pressure Cooker
Pressure cooking is the process of cooking food under high pressure steam and water or a water-based cooking liquid, in a sealed vessel known as a ''pressure cooker''. High pressure limits boiling, and creates higher cooking temperatures which cook food far more quickly. The pressure cooker was invented in the seventeenth century by the physicist Denis Papin, and works by expelling air from the vessel, and trapping steam produced from the boiling liquid. This is used to raise the internal pressure up to one atmosphere above ambient and gives higher cooking temperatures between . Together with high thermal heat transfer from steam it permits cooking in between a half and a quarter the time of conventional boiling. Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker. Modern pressure cookers have numerous safety features to prevent the pressure cooker from holding too much pressure. After cooking, the steam pressure is lowered ...
