Tom Walshaw
Tom D. Walshaw (1912–1998) was an engineer, author and contributor to the British magazines ''Model Engineer'' and ''Engineering in Miniature''. Many of his magazine contributions and books were authored under the pseudonym Tubal Cain. The pseudonym relates to the Tubal-cain, the biblical metal worker. As Tubal Cain he made over 424 contributions to ''Model Engineer'', beginning in 1971. These were mainly divided between workshop equipment articles and model stationary engine constructional articles. He graduated in mechanical engineering at Loughborough University in 1934. and eventually, after a career in mechanical design, went back to that university in 1943, becoming, after some years, senior lecturer in mechanical engineering. He went on in 1948 to teach at University of Liverpool. In 1952 he was appointed Head of Department of Mechanical, Civil and Electrical Engineering at Darlington College of Technology. His final academic post was Head of Mechanical, Production and Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Engineer Magazine
''Model Engineer Magazine'' was first published (in the United Kingdom) to support the hobby of model engineering in 1898 by Percival Marshall, who was to remain its editor for over 50 years. It has been owned by MyTime Media since 2008. The magazine addressed the emergence of a new hobby — the construction of models (often working) and experimental engineering, largely in metal. It transcended class barriers, appealing to professional engineers, jobbing machinists and anyone interested in making working mechanisms. Contributors The magazine has had many notable contributors, but foremost among these was LBSC ( pen name of Lillian 'Curly' Lawrence). From the inter-war period to the 1960s he produced many designs for simple but reliable small model steam locomotives. Most of these were published in ''Model Engineer'', and brought the construction of small passenger hauling locomotives within the reach of the typical home machinist. Other notable contributors include Henry Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six-column Beam Engine
Six-column beam engines are a type of beam engine, where the beam's central pivot is supported on a cast-iron frame or 'bedstead', supported on six iron columns. History These engines were a development after the house-built engine. Their cast-iron frames could be built and test-assembled at a factory before delivery, allowing rapid assembly or 'erection' once on site. Their main advantage was that they avoided the need for complex masonry foundations in their engine house, merely a simple level platform to which the iron frame could be bolted. The difficult alignment between their cylinder, the beam pivot and the crankshaft was all taken care of by the factory-made frame. Although the upper part of the frame only supports the beam's central pivot and any Watt's parallel motion gear, it also has an important function in stiffening the frame overall against vertical bending forces between the cylinder and crankshaft. Cast iron is weak against bending, and a shallow frame alone wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1912 Births
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Model Engineers
A model is an informative representation of an object, person or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin ''modulus'', a measure. Models can be divided into physical models (e.g. a model plane) and abstract models (e.g. mathematical expressions describing behavioural patterns). Abstract or conceptual models are central to philosophy of science, as almost every scientific theory effectively embeds some kind of model of the physical or human sphere. In commerce, "model" can refer to a specific design of a product as displayed in a catalogue or show room (e.g. Ford Model T), and by extension to the sold product itself. Types of models include: Physical model A physical model (most commonly referred to simply as a model but in this context distinguished from a conceptual model) is a smaller or larger physical copy of an object. The object being modelled may be small (for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Trevithick
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.

Blowing Engine
A blowing engine is a large stationary steam engine or internal combustion engine directly coupled to air pumping cylinders. They deliver a very large quantity of air at a pressure lower than an air compressor, but greater than a centrifugal fan. Blowing engines are majorly used to provide the air blast for furnaces, blast furnaces and other forms of smelter. Waterwheel engines The very first blowing engines were the blowing houses: bellows, driven by waterwheels. Smelters are most economically located near the source of their ore, which may not have suitable water power available nearby. There is also the risk of drought interrupting the water supply, or of expanding demand for the furnace outstripping the available water capacity. These restrictions led to the very earliest form of steam engine used for power generation rather than pumping, the water-returning engine. With this engine, a steam pump was used to raise water that in turn drove a waterwheel and thus the mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubal-cain
Tubal-cain or Tubalcain ( he, תּוּבַל קַיִן – ''Tūḇal Qayīn'') is a person mentioned in the Bible, in , known for being the first blacksmith. He is stated as the "forger of all instruments of bronze and iron". A descendant of Cain, he was the son of Lamech and Zillah. Tubal-cain was the brother of Naamah and half-brother of Jabal and Jubal. The Israeli kibbutz Tuval is named after him. Jewish narrative According to Rashi, Tubal-cain's name literally means "Cain's-Spices", with the Hebrew word Tū́ḇal () deriving from the word Tū́ḇlin () meaning spices. Rashi states that he was named this, because he "seasoned and improved the work of Cain". In other words, because he was a blacksmith, who helped to make weapons which could be used to kill more efficiently, he invokes his ancestor Cain's sin of murder. Furthermore according to Tanhuma bar Abba, one day, Tubal-cain and his father, Lamech, were hunting together with Tubal-cain serving as an aid for hi ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...
