S E W I N G M A C H I N E S Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first working sewing machine, A sewing machine is a machine used to stitch fabric and other materials together with thread . generally considered to have been the work of Englishman Thomas Saint in 1790, [1] the sewing machine has greatly improved the efficiency and productivity of the clothing industry.

H I S T O R YCharles Fredrick Wiesenthal , a German -born engineer working in England was awarded the first British patent for a mechanica l device to aid the art of sewing, in 1755. His invention consisted of a double pointed needle with an eye at one end. [2] In 1790, the English inventor Thomas Saint invente d the first sewing machine design, but he did not successfully advertise or market his invention. [3] His machine was meant to be used on leather and canvas material. It is likely that Saint had a working model but there is no evidence of one; he was a skilled cabinet maker and his device included many practically functional features: an overhanging arm, a feed mechanism (adequate for short lengths of leather), a vertical needle bar, and a looper.

His sewing machine used the chain stitch method, in which the machine uses a single thread to make simple stitches in the fabric. A sti tching awl would pierce the material and a forked point rod would carry the thread through the hole where it would be hooked underneath and moved to the next stitching place, where the cycle would be repeated, locking the stitch. [4] Saint's machine was designed to aid the manufacture of various leather goods, including saddles and bridles , but it was also capable of working with canvas, and was used for sewing ship sails . Although his machine was very advanced for the era, the concept would need s teady improvement over the coming decades before it could become a practical proposition.

William Jones started making sewing machines in 1859 and in 1860 formed a partnership with Thomas Chadwick. As Chadwick & Jones , they manufactured sewing machines at Ashton - un der -Lyne , England until 1863. Their machines used designs from Howe and Wilson produced under licence. [13] Thomas Chadwick later joined Bradbury & Co. William Jones opened a fac tory in Guide Bridge , Manchester in 1869. [14] In 1893 a Jones advertising sheet claimed that this fact ory was the "Largest Factory in England Exclusively Making First Class Sewing Machines". [15] The firm was renamed as the Jones Sewing Machine Co. Ltd and was later acquired by Brother Industries of Japan, in 1968. [16] J O N E S FA M I L Y C S M A C H I N E F R O M A R O U N D 1 9 3 5
