where was the first electric washing machine invented
Washing machine Electric washing machines were advertised and discussed in newspapers as early as 1904.[20] Alva J. Fisher has been incorrectly credited with the invention of the electric washer. The US Patent Office shows at least one patent issued before Fisher's US patent number 966677 (e.g. Woodrow's US patent number 921195). The "inventor" of the electric washing machine remains unknown.
Singer Corporation Singer consolidated enough patents in the field to enable him to engage in mass production, and by 1860, his company was the largest manufacturer of sewing machines in the world. In 1885, Singer produced its first "vibrating shuttle" sewing machine, an improvement over contemporary transverse shuttle designs; (see bobbin drivers). Singer began to market its machines internationally in 1855 and won first prize at the Paris World's Fair. The company demonstrated the first workable electric sewing machine at the Philadelphia electric exhibition in 1889 and began mass-producing domestic electric machines in 1910. Singer was also a marketing innovator and was a pioneer in promoting the use of installment payment plans.
