Steam Boat
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. The term ''steamboat'' is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship. 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. Background Limitations of the Newcomen steam engine The first 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 heavy weight of the Newcomen engine required a structurally strong boat, and the reciprocating motion of the engine beam required a complicated mechanism to produce propulsion. Rotary motion engines James Watt's design improveme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a steam c ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...

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. The ''Pyroscaphe'' was propelled by a double-acting steam engine and sidewheels, and was therefore a paddle steamer A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wh .... Little is known about the design of ''Pyroscaphe'', a ...

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 the 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 ...

Thomas Newcomen
Thomas Newcomen (; February 1664 – 5 August 1729) was an English inventor, creator of the Newcomen atmospheric engine, atmospheric engine in 1712, Baptist lay preacher, preacher by calling and ironmonger by trade. He was born in Dartmouth, Devon, Dartmouth, in Devon, England, to a merchant family and baptized 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 minister John Flavel to Dartmouth. Later one of Newcomen's business contacts in London, Edward Wallin, was another Baptist mi ...

Jonathan Hulls
Jonathan Hulls or Hull (baptised 1699 – 1758) was an English inventor, a pioneer of steam navigation. Traditionally, he was recognised as the first person to make practical experiments with steam to propel a vessel; but evidence to substantiate the claim that he did more than propose a steam vessel on paper is lacking. Life Hulls was born at Hanging Aston, Gloucestershire. It has been suggested that the background to the efforts of Hulls was the 1734 publication in the abridged ''Philosophical Transactions'' of a paper by the French engineer Monsieur Duquet on ships and mechanical propulsion. Duquet was a controversialist also active at that time in a debate on his ideas with Henri Pitot. He died in the middle of 1758 in Broad Campden, where he had lived almost all his adult life. Work The protection of his invention by Hulls depended on the financial support of his neighbour named Freeman at Batsford Park. The patent for the invention by Hulls is dated 21 December 1736, and hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Allen (physician)
John Allen, or John Alleyn (1660? – 1741), was an English physician and inventor, mainly remembered for writing medical text books. Biography Allen, the date of whose birth is not positively known, was an M.D., but of what university does not appear. He was admitted extra-licentiate of the College of Physicians on 13 September 1692; practised, and apparently died, at Bridgwater, Somerset. Allen published in 1719 ''Synopsis universæ Medicinæ practicæ; sive doctissimorum Virorum de Morbis eorumque causis ac remediis judicia'', a work which became extremely popular, being printed in many editions at home and abroad, both in Latin and translated into modern languages. This work claims to be entirely practical, and not to deal with the new views and hypotheses which abounded in the medicine of the time, but makes no pretensions to originality. It gives, under the head of each disease, the opinions of various authors, ancient and modern, to which the writer added, especially in l ...

Pressure Cooker
A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure. The prototype of the modern pressure cooker was the steam digester invented in the seventeenth century by the physicist Denis Papin. It 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 as well as saving considerable energy. Almost any food that can be cooked in steam or water-based liquids can be cooked in a pressure cooker. Modern pressure cookers have many safety f ...
