Kinneil Engine
''Old Bess'' is an early beam engine built by the partnership of Boulton and Watt. The engine was constructed in 1777 and worked until 1848. The engine is most obviously known simply for being an early example of an engine built by Boulton and Watt. However it also played a far more important role in the development of steam engines for being the first engine designed to work with an early cutoff, and so to use the expansion of the steam for greater efficiency. It is now preserved in the Power Gallery of the Science Museum, London. It is the oldest surviving Watt engine, and the third-oldest surviving beam engine. Watt's previous Kinneil Engine Watt's first engine at Kinneil in Scotland had been unsuccessful, and the parts were taken down and re-used at Boulton's Soho Manufactory in Birmingham. The reworked engine was more successful there, and encouraged Boulton to invest further in this developing steam technology and in Watt's inventions. The Manufactory had been bui ...

This collection contained many of the most famous exhibits of what is now t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinneil House
Kinneil House is a historic house to the west of Bo'ness in east-central Scotland. It was once the principal seat of the Duke of Hamilton, Hamilton family in the east of Scotland. The house was saved from demolition in 1936 when 16th-century mural paintings were discovered, and it is now in the care of Historic Environment Scotland. The house now consists of a symmetrical mansion built in 1677 on the remains of an earlier 16th- or 15th-century tower house, with two rows of gunloops for early cannon still visible. A smaller east wing, of the mid 16th century, contains the two painted rooms. The house is protected as a Category A listed building. It sits within a public park, which also incorporates a section of the Roman Antonine Wall and the only example of an Antonine Castellum, fortlet with visible remains. Early history The lands of Kinneil with Larbert and Auldcathy were given to Walter Fitz Gilbert, an ancestor of the Hamilton family, by Robert the Bruce in 1323. A charte ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Lead (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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Small
William Small (13 October 1734 – 25 February 1775) was a Scottish physician and a professor of natural philosophy at the College of William and Mary in Virginia, where he became an influential mentor for Thomas Jefferson. Early life William Small was born in Carmyllie, Angus, Scotland, the son of a Presbyterian minister, James Small and his wife Lillias Scott, and younger brother to Dr Robert Small. He attended Dundee Grammar School, and Marischal College, University of Aberdeen where he received an MA in 1755. In 1758, he was appointed Professor of Natural Philosophy at the College of William and Mary in Williamsburg, Virginia, then one of Britain's American colonies. Jefferson's Professor Small is known for being Thomas Jefferson's professor at William and Mary, and for having an influence on the young Jefferson. Small introduced him to members of Virginia society who were to have an important role in Jefferson's life, including George Wythe a leading jurist in the colon ...

Simple Expansion Steam Engine
A compound engine is an engine that has more than one stage for recovering energy from the same working fluid, with the exhaust from the first stage passing through the second stage, and in some cases then on to another subsequent stage or even stages. Originally invented as a means of making steam engines more efficient, the compounding of engines by use of several stages has also been used on internal combustion engines and continues to have niche markets there. The stages of a compound engine may be either of differing or of similar technologies, for example: * In a turbo-compound engine, the exhaust gas from the cylinders passes through a turbine, the two stages being dissimilar. * In a compound steam locomotive, the steam passes from the high-pressure cylinder or cylinders to the low-pressure cylinder or cylinders, the two stages being similar. * In a triple-expansion steam engine, the steam passes through three successive cylinders of increasing size and decreasing pressu ...

Rotative Beam Engine
A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate condenser; Jonathan Hornblower and Arthur Woolf, who compounded the cylinders; and William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a mill. The rotative beam engine is a later design of beam engine where the connecting rod drives a flywheel by means of a crank (or, historically, by means of a sun and planet gear). These beam engines could be used to directly power the line-shafting in a mill. They also could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-returning Engine
A water-returning engine was an early form of stationary steam engine, developed at the start of the Industrial Revolution in the middle of the 18th century. The first beam engines did not generate power by rotating a shaft but were developed as water pumps, mostly for draining mines. By coupling this pump with a water wheel, they could be used to drive machinery. The steam engine was not, as widely held, the ''cause'' of the Industrial Revolution, but rather arose as a result of it. The primary power source of the Revolution, certainly in the 18th century, was the water wheel, not the steam engine. The need for an independent prime-mover Blowing engines The origins of the water-returning engine begin with blowing engines used to provide the draught for blast furnaces and smelters. Although early furnaces may have been powered by human- or animal-powered bellows, once the Industrial Revolution began the new enlarged furnaces were blown by water wheel-powered blowing houses.

Water Wheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
