Charles Hotchkiss Norton
Charles Hotchkiss Norton (November 23, 1851, Plainville, Connecticut – October 27, 1942, Plainville, Connecticut) was an American mechanical engineer and designer of machine tools. After working for the Seth Thomas Clock company in Thomaston, in 1886 Norton became Assistant Engineer with the Brown & Sharpe Manufacturing Company at Providence, Rhode Island, redesigning their universal grinding machine. In 1890 he became a partner in the newly established Leland, Faulconer & Norton Company at Detroit, Michigan, designing and constructing machine tools. Returning to Brown & Sharpe in 1896, he designed a grinding machine with larger and heavier grinding wheels, capable of supplying machine parts for the emerging automobile industry. In 1900 he left Brown & Sharpe to found the Norton Grinding Company in Worcester, Massachusetts with support from the Norton Emery Wheel Company (founded by an unrelated Norton); the two firms merged in 1919, with Norton as their Chief Engineer until 1934, ...

Plainville, Connecticut
Plainville is a town in Hartford County, Connecticut, United States. The population was 17,525 at the 2020 census. History Plainville first was inhabited by Europeans around 1650. By the 1660s, the land was incorporated as land for nearby Farmington. In the year 1869, it separated from Farmington due to the distance of the town center and the growth of Plainville downtown due to the installation of the New York, New Haven and Hartford Railroad and the Hartford, Providence, and Fishkill Railroad.

Machine Tool
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the work piece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or " freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. The precise definition of the term ''machine tool'' varies among users, as discussed below. While all machine tools are "machines that help people to make things", not all factory machines are machine tools. Today machine ...

Thomaston, Connecticut
Thomaston is a town in Litchfield County, Connecticut, United States. The population was 7,442 at the 2020 census. The urban center of the town is the Thomaston census-designated place, with a population of 1,928 at the 2020 census. History The town, originally part of the town of Plymouth and referred to as "Plymouth Hollow", was first settled by Henry Cook ("the soldier in the wilderness", 1683–1750) around 1728. The town is known for clockmaking, which started in 1803, when Eli Terry established a factory in the town. Terry brought mass production to the clockmaking industry, helping to reduce the cost of clocks. He introduced and patented the shelf clock in 1814, which reduced the cost of a clock from $25 to $5. His clocks were sold throughout the United States. The town was incorporated in its own right and under the name "Thomaston" in 1875. The name derives from Seth Thomas, the early clockmaker, who established a factory in town in 1812. The Seth Thomas clock factory ...

Providence, Rhode Island
Providence is the capital and most populous city of the U.S. state of Rhode Island. One of the oldest cities in New England, it was founded in 1636 by Roger Williams, a Reformed Baptist theologian and religious exile from the Massachusetts Bay Colony. He named the area in honor of "God's merciful Providence" which he believed was responsible for revealing such a haven for him and his followers. The city developed as a busy port as it is situated at the mouth of the Providence River in Providence County, at the head of Narragansett Bay. Providence was one of the first cities in the country to industrialize and became noted for its textile manufacturing and subsequent machine tool, jewelry, and silverware industries. Today, the city of Providence is home to eight hospitals and List of colleges and universities in Rhode Island#Institutions, eight institutions of higher learning which have shifted the city's economy into service industries, though it still retains some manufacturin ...

Grinding Machine
A grinding machine, often shortened to grinder, is a power tool (or machine tool) used for grinding. It is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field. Overview The grinding machine consists of a bed with a fixture to guide and hold the workpiece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grinding Wheel
Grinding wheels contains abrasive compounds for grinding and abrasive machining operations. Such wheels are also used in grinding machines. The wheels are generally made with composite material . This consists of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the ''bond'' in grinding wheel terminology) to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Today most grinding wheels are artificial composites made with artificial aggregates, but the history of grinding wheels began with natural composite stones, such as those used for millstones. The manufacture of these wheels is a precise and tightly controlled process, due not only to the inherent safety risks of a spinning disc, but also the composition and uniformity required to prevent that disc from exploding due to t ...

Automobile Industry
The automotive industry comprises a wide range of companies and organizations involved in the design, development, manufacturing, marketing, and selling of motor vehicles. It is one of the world's largest industries by revenue (from 16 % such as in France up to 40 % to countries like Slovakia). It is also the industry with the highest spending on research & development per firm. The word ''automotive'' comes from the Greek ''autos'' (self), and Latin ''motivus'' (of motion), referring to any form of self-powered vehicle. This term, as proposed by Elmer Sperry (1860-1930), first came into use with reference to automobiles in 1898. History The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, and the U.S. automobile industry produced over 90% of them ...

Charles H
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its de ...
