Since those early days, many people don dey involved for the process of developing machine wey fit do the same thing quick quick and with better efficiency.

Charles Wiesenthal, wey be German, design and receive patent for double-pointed needle wey eliminate the need to turn the needle around with each stitch for England for 1755. Other inventors for that time try to develop sewing machine wey work, but each design get at least one serious problem.

Frenchman Barthelemy Thimonnier finally create machine wey really work. But e nearly die as group of angry tailors burn down hin garment factory. Dem dey fear say dem go lose their jobs to the machine.

American inventor Elias Howe, wey be born on July 9, 1819, get patent for method of sewing wey use thread from two different sources. Howe's machine get needle wey get eye for the point, and e use the two threads to make special stitch wey dem call lockstitch. But Howe get problem to find buyers for hin machines for America. For frustration, e travel go England to try sell hin invention there. When e finally come back home, e see say plenty manufacturers dey adapt hin discovery for their own sewing machines.

Isaac Singer, another American inventor, na manufacturer wey improve the design of sewing machines. E invent up-and-down-motion mechanism wey replace the side-to-side machines. E also develop foot treadle to power hin machine. This improvement make the sewer's hands free. E sure say e be big improvement from the hand-cranked machine of the past. Soon, the Singer sewing machine get more fame pass others because e dey more practical. E fit use for house and e fit be bought on hire-purchase. The Singer sewing machine become the first house appliance, and the Singer company become one of the first American multinationals.

But Singer use the same method to create lockstitch wey Howe don already patent. As result, Howe accuse am of patent infringement. Of course, Elias Howe win the court case, and Singer dey order to pay Howe royalties. For the end, Howe become millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for hin invention.
