Chainsaws
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chainsaw Mill
A chainsaw mill or PortaMill or Alaskan mill or Alaskan sawmill or Logosol sawmill is a type of sawmill incorporating a chainsaw, that is used by one or two operators to mill logs into lumber for use in furniture, construction and other uses. Description The mill attachment consists of a pair of guide rails which are attached to the bar of the chainsaw. The rails ride for the first cut on a plank or on a metal ladder which is screwed to the log (but not so tightly that the guide is pulled out of plane), and then on the previously cut surface of the log, and guide the chainsaw blade through the log at a consistent depth so that planks of a chosen thickness are cut. The distance between the rails and the bar determines this thickness and it can be adjusted by moving the rails along a post at each end of the mill attachment. During use it is important that the rails extend out past the ends of the log so the cut has support the entire time. Small mills use a single chainsaw and ...

Andreas Stihl
Andreas Stihl (10 November 1896 in Zürich, Switzerland – 14 January 1973 in Rohrbronn, Baden-Württemberg, Germany) was a Swiss-born German engineer and important inventor in the area of chainsaws, and the founder of Andreas Stihl AG & Company KG. He is often hailed as the "Father of the chainsaw". Early life Stihl went to the Volksschule in Zürich, before moving to relatives in Germany. He attended the Realschule in Singen (Baden-Württemberg) and the Gymnasium in Düsseldorf-Oberkassel. From 1915 until his dismissal by injuries in 1917, Stihl fought in the First World War in the German Army. From 1917 until 1920, he studied mechanical engineering in Eisenach. Invention of the chainsaw In 1923, together with his friend Carl Hohl, he founded an engineering firm in Stuttgart, which was dissolved in 1926. Stihl founded a new company, for steam boiler prefiring systems, in the same year. He also patented the "Cutoff Chainsaw for Electric Power" in 1926, which weigh ...

Limbing
Limbing or delimbing is the process of removing branches from a standing or fallen tree trunk. In logging, limbing follows felling. Limbing plays a role in fire prevention by removing branches from live trees that can otherwise serve as part of a fuel ladder allowing a fire to climb from the ground into the tree canopy. A California fire prevention guide recommends to "Remove all tree branches at least 6 feet .8 metersfrom the ground" and "Allow extra vertical space between shrubs and trees." Ready For Wildfire, In , limbing can be synonymous w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gigli Saw
A Gigli saw is a flexible wire saw used by surgeons for bone cutting. A Gigli saw is used mainly for amputation, where the bones have to be smoothly cut at the level of amputation.Kojiro Wada, Kentaro Mori, Terushige Toyooka, Naoki Otani, Kazuya Fujii, Hideaki Ueno, Satoshi Tomura, Arata Tomiyama, Safe fronto-orbito-zygomatic osteotomy using a diamond-coated threadwire saw in orbito-zygomatic craniotomy, in Asian J Neurosurg, vol. 10, n. 3, 2015, pp. 250-252 The saw was invented by Italian obstetrician Leonardo Gigli to simplify the performance of a lateral pubiotomy in obstructed labour.

Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be co ...

Joseph Buford Cox
Joseph Buford Cox (1905 – August 10, 2002), was an American inventor and businessman. He invented what is now known as the chipper type chain for chain saws. He based his design on the C-shaped jaws of the larva of the timberman beetle. Cox watched the destructive larvae of the timber beetle (Ergates spiculatus) for many hours. The beetle's cutting action was left and right, side to side, rather than scratching or burrowing straight ahead. Cox adapted this concept to a new chain saw of his own design put into production during the late 1940s. Joseph and his wife, Alice, founded "The Oregon Saw Chain Co." in 1947. Cox later started a small casting company called OMARK, now known as "Omark Industries". In time, Oregon Saw Chain became a subsidiary of Omark Industries which was in turn acquired in 1985 by Blount, Inc., of Montgomery, Alabama. Blount merged in 1999 with Lehman Brothers Merchant Banking Partners Trilantic Capital Partners (Trilantic) is a global private equity firm fo ...
