Woolf Compound Engine
Arthur Woolf (1766, Camborne, Cornwall – 16 October 1837, Guernsey) was a Cornish engineer, most famous for inventing a high-pressure compound steam engine. As such he made an outstanding contribution to the development and perfection of the Cornish engine. Woolf left Cornwall in 1785 to work for Joseph Bramah's engineering works in London. He worked there and at other firms as an engineer and engine builder until 1811 experimenting with high pressure steam and a much improved boiler. Whereupon he returned to Cornwall. Michael Loam, inventor of the man engine, was trained by him. When he returned to Cornwall, beam engine designs were crude, shackled by outdated Watt patents and poor engineering, struggling to compete with large water wheels, even used underground. He learned from Bramah that to move forward meant adopting much improved engineering techniques, for it was Bramah who invented quality control. Woolf was chief engineer to Harvey & Co of Hayle, the leading engin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Camborne
Camborne ( kw, Kammbronn) is a town in Cornwall, England. The population at the 2011 Census was 20,845. The northern edge of the parish includes a section of the South West Coast Path, Hell's Mouth and Deadman's Cove. Camborne was formerly one of the richest tin mining areas in the world and home to the Camborne School of Mines. Toponymy Craig Weatherhill explains Camborne thus: "''Cambron'' c. 1100 - 1816) Cambron, ?'crook-hill')" Kammbronn is Cornish for 'crooked hill'. The word 'kamm', crooked, is the same in the Breton language, and the Welsh, Gaelic and Irish Gaelic word is 'cam'. 'Hill' in Welsh is 'bryn'. Geography Camborne is in the western part of the largest urban and industrial area in Cornwall with the town of Redruth east. It is the ecclesiastical centre of a large civil parish and has a town council. Camborne-Redruth is on the northern side of the Carn Brea/ Carnmenellis granite upland which slopes northwards to the sea. The two towns are linked by the ...

Hamilton Waterworks
The Hamilton Waterworks, also known as the Hamilton Waterworks Pumping Station, is a National Historic Site of Canada located in Hamilton, Ontario. It is an industrial water works structure built in the Victorian style, and a rare example of such a structure in Canada to be "architecturally and functionally largely intact". It is currently used to house the Museum of Steam and Technology. Its construction began in 1856, with the work contracted to local stonemason George Worthington, and was completed by 1859. It was opened on 18 September 1860 by Edward VII, at the time the Prince of Wales, during a two-month royal tour to Canada. It was formally designated a heritage site on 17 November 1977, and listed as a National Historic Site of Canada on 12 June 2007. Background In 1833, Hamilton's water system consisted of five wells. A December 1853 report to city standing committee on fire and water, prepared by William Hodgins, proposed a public water system using Ancaster Creek as ...

Claymills Pumping Station
Claymills Pumping Station is a restored Victorian sewage pumping station on the north side of Burton upon Trent, Staffordshire, England. It was designed by James Mansergh and used to pump sewage to the sewage farm at Egginton. The main pumping plant consists of four Woolf compound, rotative, beam pumping engines. These are arranged in mirror image pairs, in two separate engine houses, with a central boiler house (containing five Lancashire boilers with economisers) and chimney. The engines were built in 1885 by Gimson and Company of Leicester. All the engines are similar, and the following description is limited to only one, but applicable to all. The high-pressure cylinder is 24-inch bore by 6-foot stroke, and the low-pressure cylinder is 38-inch bore by 8-foot stroke. Steam is distributed by means of double beat 'Cornish' valves, mounted in upper and lower valve chests. The cylinders act on one end of the beam, via Watt's parallel motion. The beam itself is 26 feet 4 i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Blagdon Lake
Blagdon Lake lies in a valley at the northern edge of the Mendip Hills, close to the village of Blagdon and approximately south of Bristol, England. The lake was created by Bristol Water (Bristol Waterworks Company as it was known then), when it dammed the River Yeo, starting construction in 1898, to designs by Charles Hawksley, and completing this in 1905. The Wrington Vale Light Railway was constructed primarily to bring building materials for the lake. The reservoir was formed by the construction of a dam and provided water to the pumping station which originally contained four Woolf compound rotative beam pumping engines, built by Glenfield & Kennedy of Kilmarnock, which have now been replaced by electric pumps. Two of the steam engines have been preserved, with one in working order as part of the visitor centre which also includes educational facilities for children. The pumping station is now a Grade II* listed building. The lake still provides of drinking water e ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Abbey Pumping Station
The Abbey Pumping Station is a museum of science and technology in Leicester, England, on Corporation Road, next to the National Space Centre. With four working steam-powered beam engines from its time as a sewage pumping station, it also houses exhibits for transport, public health, light and optics, toys and civil engineering. Sewage pumping station The building was constructed in 1891 by Leicester Corporation on the north side of Leicester, alongside the River Soar, as a pumping station used to pump the town's sewage to the sewage farm at Beaumont Leys. The grand Victorian building, designed by Stockdale Harrison (Leicester architect) in 1890, houses four Arthur Woolf compound beam engines built by Gimson and Company of Leicester. The first attempt to respond to the population's sewage disposal was in 1850 when piped water made water closets possible, and Thomas Wicksteed designed and built sewers leading to a sedimentation and de-oderisation treatment works on the northern, ...

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]   |

Plunger Pump
A plunger pump is a type of positive displacement pump where the high-pressure seal is stationary and a smooth cylindrical plunger slides through the seal. This makes them different from piston pumps and allows them to be used at higher pressures. This type of pump is often used to transfer municipal and industrial sewage. History The invention of the plunger pump is attributed to Samuel Morland based on a patent of 1675. Operation Piston pumps and plunger pumps are positive displacement pumps that use a plunger or piston to move media through a cylindrical chamber. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Rotary piston and plunger pumps use a crank mechanism to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The pressure in the chamber actuates the valves at both the suction and discharge points. Plunger pumps are used in appli ...

Double-acting Cylinder
In mechanical engineering, the cylinders of reciprocating engines are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston. Single-acting A single-acting cylinder in a reciprocating engine is a cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of reciprocating engine. They are almost universal in internal combustion engines (e.g. petrol and diesel engines) and are also used in many external combustion engines such as Stirling engine A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the ''working fluid'') between different temperatures, resulting in a net conversion of heat energy to mechanical work.

Jonathan Hornblower
Jonathan Hornblower (5 July 1753 – 23 February 1815) was an English pioneer of steam power. Personal life The son of Jonathan Hornblower the Elder and the brother of Jabez Carter Hornblower, two fellow pioneers, the young Hornblower was educated at Truro Grammar School. He was baptised at Trelever on 25 July 1773, aged 20 (he and his family were much involved in Baptist churches in Cornwall), and was apprenticed to a metal-working tradesman at Penryn. He married twice, first to his cousin Rosamund Phillips in 1775 and later to Elizabeth Jordan with whom he had two surviving daughters, Rosamund (1789) and Elizabeth (1790). He died on 23 February 1815 and is buried in St Gluvias Churchyard. Compound engine He invented the compound steam engine in 1781 and patented it on 16 July in the same year. This type of engine has two cylinders, an evolution from the single low pressure, condensing engines of Newcomen and later Watt (who introduced the separate condenser), it introd ...

Watt Steam Engine
The Watt steam engine design became synonymous with steam engines, and it was many years before significantly new designs began to replace the basic Watt design. The first steam engines, introduced by Thomas Newcomen in 1712, were of the "atmospheric" design. At the end of the power stroke, the weight of the object being moved by the engine pulled the piston to the top of the cylinder as steam was introduced. Then the cylinder was cooled by a spray of water, which caused the steam to condense, forming a partial vacuum in the cylinder. Atmospheric pressure on the top of the piston pushed it down, lifting the work object. James Watt noticed that it required significant amounts of heat to warm the cylinder back up to the point where steam could enter the cylinder without immediately condensing. When the cylinder was warm enough that it became filled with steam the next power stroke could commence. Watt realised that the heat needed to warm the cylinder could be saved by adding ...
