Lockstitch is named because the two threads, upper and lower, "lock" (entwine) together in the hole in the fabric which they pass through. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, through the take-up arm, and finally through the hole in the needle.
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. However, due to the ...
Another one of Tracy’s prominent innovations was her lock-stitch and chain-stitch sewing machine. This sewing machine was so impressive, for its time, because “her improved bobbin which held up to 1,000 yards of thread hence reducing the number of times the bobbin thread had to be replaced, making it a time saver”. [10] These sewing ...
Allen Benjamin Wilson (1823–1888) was an American inventor famous for designing, building and patenting some of the first successful sewing machines. [1] He invented both the vibrating and the rotating shuttle designs which, in turns, dominated all home lockstitch sewing machines. With various partners in the 19th century he manufactured ...
1833 Sewing machine (lock-stitch) Most modern sewing machines use the lockstitch technique of sewing invented by Walter Hunt, which consists of two threads, an upper and a lower. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the ...
Older sewing machines designed to sew only a straight stitch can be adapted to sew a zigzag by means of an attachment. The attachment replaces the machine's presser foot with its own, and draws mechanical power from the machine's needle clamp (which requires the needle clamp to have a side-facing thumbscrew). It creates a zigzag by mechanically ...
The tight-locked stitches made by home sewing machines, and the use of Western clothing patterns, led to a movement towards wearing Western-style clothing during the early 20th century. [23] Western sewing and clothing styles were disseminated in sub-Saharan Africa by Christian missionaries from the 1830s onward.
Merrow's original three-thread overedge sewing machine is the forerunner of contemporary overlocking machines. Over time, the Merrow Machine Company pioneered the design of new machines to create a variety of overlock stitches, such as two- and four-thread machines, the one-thread butted seam, and the cutterless emblem edger.
