GENERAL KNOWLEDGE

Detailed explanation-1: -Elias Howe patented the first ever lockstitch sewing machine in the world in 1846. His invention helped the mass production of sewing machines and clothing. That in turn revolutionized the sewing industry and freed women from some of the drudgery of daily life at the time.

Detailed explanation-2: -The first machine to combine all the disparate elements of the previous half-century of innovation into the modern sewing machine was the device built by English inventor John Fisher in 1844, a little earlier than the very similar machines built by Isaac Merritt Singer in 1851, and the lesser known Elias Howe, in 1845.
