Simeon North (July 13, 1765 – August 25, 1852) was an American gun manufacturer, who developed one of America's first milling machines (possibly the very first) in 1818 and played an important role in the development of interchangeable parts manufacturing.
Muir, Merritt Roe Smith, and Robert B. Gordon all agree that before 1832 both Simeon North and John Hall were able to mass-produce complex machines with moving parts (guns) using a system that entailed the use of rough-forged parts, with a milling machine that milled the parts to near-correct size, and that were then "filed to gage by hand with ...
Machine tool historian Joseph W. Roe credited Whitney with inventing the first milling machine circa 1818. Subsequent work by other historians (Woodbury; Smith; Muir; Battison [cited by Baida [ 15 ] ]) suggests that Whitney was among a group of contemporaries all developing milling machines at about the same time (1814 to 1818), and that the ...
The first man-made diffraction grating was invented around 1785 in Philadelphia by David Rittenhouse who strung 50 hairs between two finely threaded screws with an approximate spacing of about 100 lines per inch. [28] 1787 Automatic flour mill. Classical mill designs were generally powered by water or air.
The "American method" was reintroduced to the UK in the 1850s, when Colt executed on order on naval revolvers in Pimlico, and strikes of London and Birmingham gunmakers during the war made the War Office realize the usefulness of being able to employ low-skilled workers, so milling machines were bought and installed at the Royal Small Arms ...
In 1783, Samuel Rehe invented a true milling machine. [20] In 1795, Eli Terry began using a milling machine at Plymouth Connecticut in the production of tall case clocks. With the use of his milling machine, Terry was the first to accomplish Interchangeable parts in the clock industry. Milling wooden parts was efficient in interchangeable parts ...
Cyrus McCormick's reaper (invented in 1834) allowed farmers to quadruple their harvesting efficiency by replacing hand labor with a mechanical device. John Deere invented the steel plow in 1837, keeping the soil from sticking to the plow and making it easier to farm in the rich prairies of the Midwest. The harvester, self-binder, and combine ...
North eventually made progress toward some degree of interchangeability and developed special machinery. North's shop used the first known milling machine (c. 1816), a fundamental machine tool. [90] The experience of the War of 1812 led the War Department to issue a request for contract proposals for firearms with interchangeable parts ...
