History
Conclusion
The advanced scientific techniques employed in the construction of industrial sewing machines represented a tremendous step forward from the crude tools used in the development of early sewing equipment between 1845 and 1945.
These machines with their reciprocating, rotating, and oscillating motions operating at terrifically high speeds embodied one of the most unique mechanisms·in common use and far surpassed many so-called precision mechanical devices.
Such brilliant performance required close adherence to standards of accuracy — not the accuracy that divides an inch into a thousand parts — but the accuracy of light that divides each thousandth into tenths of thousandths and translates that infinitesimal fraction into everyday working dimensions.
Such was the sewing machine one hundred years after Elias Howe's invention.
