James White (inventor)
James White (1762 – 17 December 1825) was an English civil engineer and inventor. Born in Cirencester, he held an intense interest in mechanics at a young age. Moving to London in the 1780s, he created and patented various inventions, including a Differential (mechanical device), differential gear train and a model harbor crane. He moved to Paris in 1792, shortly following the French Revolution, and continued work in designing industrial machinery. Inventions from his period in Paris include an Articulated vehicle, articulated or "serpentine" barge, a new form of turbine, and an automatic wire nail-making machine. He presented a novel straight-line mechanism at the 1801 Exposition des produits de l'industrie française at the Louvre, and was awarded a medal by Napoleon, Napoleon Bonaparte. He returned to England following the end of the Napoleonic Wars, and settled in the industrial and manufacturing center of Manchester. He published ''A New Century of Inventions'' in 1822, de ...

Chinese Windlass
The windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. The Greek scientist Archimedes was the inventor of the windlass. A surviving medieval windlass, dated to –1400, is in the Church of St Mary and All Saints, Chesterfield. The oldest depiction of a windlass for raising water can be found in the Book of Agriculture published in 1313 by the Chinese official Wang Zhen of the Yuan Dynasty ( 1290–1333). Uses * Vitruvius, a military engineer writing about 28 BC, defined a machine as "a combination of timber fastened together, chiefly efficacious in moving great weights". About a century later, Hero of Alexandria summarized the practice of his day by naming the "five simple machines" for "moving a given weight by a given f ...

Micrometer (device)
A micrometer, sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw for Accuracy and precision, accurate measurement of the size of components. It widely used in mechanical engineering, machining, metrology as well as most mechanical trades, along with other dimensional instruments such as Caliper#Dial caliper, dial, Caliper#Vernier caliper, vernier, and Caliper#Digital caliper, digital calipers. Micrometers are usually, but not always, in the form of calipers (opposing ends joined by a frame). The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil. History The word ''micrometer'' is a classical compound, neoclassical coinage from and . According to the Webster's Dictionary#Merriam-Webster Collegiate Dictionary, ''Merriam-Web ...

Clockmaker
A clockmaker is an artisan who makes and/or repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches. Clockmakers must be able to read blueprints and instructions for numerous types of clocks and time pieces that vary from antique clocks to modern time pieces in order to fix and make clocks or watches. The trade requires fine motor coordination as clockmakers must frequently work on devices with small gears and fine machinery. Originally, clockmakers were master craftsmen who designed and built clocks by hand. Since modern clockmakers are required to repair antique, handmade or one-of-a-kind clocks for which parts are not available, they must have some of the design and fabrication abilities of the original craftsmen. A qualified clockmaker can typically design and make a missing piece for a clock with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Millstone
Millstones or mill stones are stones used in gristmills, used for triturating, crushing or, more specifically, grinding wheat or other grains. They are sometimes referred to as grindstones or grinding stones. Millstones come in pairs: a stationary base with a convex rim known as the bedstone (or nether millstone) and a concave-rimmed runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones. Millstones are constructed so that their shape and configuration help to channel ground flour to the outer edges of the mechanism for collection. The runner stone is supported by a cross-shaped metal piece ( millrind or rynd) fixed to a "mace head" topping the main shaft or spindle leading to the driving mechanism of the mill (wind, water (including tide), or other means). History The origins of an industry Often referred to as the "oldest industry", the use of the millstone is inextr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
