The American system of manufacturing was a set of manufacturing methods that evolved in the 19th century. [1] The two notable features were the extensive use of interchangeable parts and mechanization for production, which resulted in more efficient use of labor compared to hand methods.
The very first mass production using interchangeable parts in America was Eli Terry's 1806 Porter Contract, which called for the production of 4000 clocks in three years. [18] During this contract, Terry crafted four-thousand wooden gear tall case movements, at a time when the annual average was about a dozen. [ 19 ]
Productivity-improving technologies date back to antiquity, with rather slow progress until the late Middle Ages. Important examples of early to medieval European technology include the water wheel, the horse collar, the spinning wheel, the three-field system (after 1500 the four-field system—see crop rotation) and the blast furnace.
By the beginning of the Civil War, rifles with interchangeable parts had been developed, and after the war, more complex devices such as sewing machines and typewriters were made with interchangeable parts. [31] In 1798, Eli Whitney obtained a government contract to manufacture 10,000 muskets in less than two years.
While the First Revolution was driven by limited use of steam engines, interchangeable parts and mass production, and was largely water-powered, especially in the United States, the Second was characterized by the build-out of railroads, large-scale iron and steel production, widespread use of machinery in manufacturing, greatly increased use ...
Mass production, also known as flow production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. [1]
Like other Fed officials, Cook cited several possible causes: The more efficient job matching that allowed Cordero to find a better use of her skills; sustained high levels of business formation ...
The Waltham mill also pioneered the process of mass production, which greatly increased the scale of manufacturing. Water-powered line shafts and belts connected hundreds of power lines. The increase in manufacturing occurred so rapidly that there was no localized labor supply in the early 19th century that could have sufficed. [ 4 ]
