Two decades later, when the patents had expired and the Sewing Machine Combination patent pool had dispersed, White Sewing Machine Company employees D'Arcy Porter and George W. Baker built a new machine that made successful use of it. The "White Sewing Machine", as it was first named, entered production in 1876. It was popular in its time, and ...
The thread tension mechanisms, one for the upper thread and one for the lower thread, prevent either thread from pulling the entwine point out of the middle of the material. Prior to the invention of the rotating hook, lockstitch machines placed the lower bobbin inside a miniature shuttle which would be passed through the loop formed when the ...
A free arm houses the machine's feeder and bobbin driver in a tubular arm-shaped bed, enabling material to be wrapped around the mechanism during sewing rather than simply resting on top of it. A free arm greatly simplifies sewing tasks like darning and hemming on delicate fabrics and difficult-to-reach seams—uses for which Elna was heavily ...
Early sewing machines of the 19th century oscillate their shuttles back and forth on linear horizontal tracks—an arrangement called a "transverse shuttle". A vibrating shuttle machine, by contrast, 'vibrates' its shuttle in a circular arc. This movement represents less total mechanical motion, which means less friction, less wear, higher ...
Isaac Merritt Singer (October 27, 1811 – July 23, 1875) was an American inventor, actor, and businessman. He made important improvements in the design of the sewing machine [1] and was the founder of what became one of the first American multi-national businesses, the Singer Sewing Machine Company.
A special loose loop stitch used for this purpose is called a 'tack' or 'tailor's tack'. This is often done through two opposing layers of the same fabric so that when the threads are snipped between the layers the stitches will be in exactly the same places for both layers thus saving time having to chalk and tack the other layer.
It is often done by hand, but using a sewing machine is also possible. Hand darning employs the darning stitch , a simple running stitch in which the thread is "woven" in rows along the grain of the fabric, with the stitcher reversing direction at the end of each row, and then filling in the framework thus created, as if weaving.
Sewing with Nancy is a half-hour show that Zieman co-produced on Wisconsin Public Television. [3] On the air since September 1982, Sewing with Nancy is the longest running sewing program on North American television, with over 900 episodes filmed. According to her autobiography, "In terms of years, only Letterman had a longer run."
