A vibrating shuttle is a bobbin driver design used in home lockstitch sewing machines during the second half of the 19th century and the first half of the 20th century. It supplanted earlier transverse shuttle designs, but was itself supplanted by rotating shuttle designs.
To make one stitch, the machine lowers the threaded needle through the cloth into the bobbin area, where a rotating hook (or other hooking mechanism) catches the upper thread at the point just after it goes through the needle. The hook mechanism carries the upper thread entirely around the bobbin case so that it has made one wrap of the bobbin ...
The rotary hook or rotating hook is a bobbin driver design used in lockstitch sewing machines since the 19th century. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today.
Transverse shuttles carry the bobbin in a boat-shaped shuttle, and reciprocate the shuttle along a straight horizontal shaft. The design was popularized in Singer's 'New Family' machine. [2] The design became obsolete once the other bobbin driver designs were developed. [3] Shuttle from a transverse shuttle bobbin driver
Singer made an attachment similar to its buttonholer, and using a similar needle-clamp-powered locomotion, in order to confer some zigzagging ability on its straight-stitch machines. Of the variety of "Singer Automatic Zigzagger" attachments produced over the years, two are compatible with 27-series machines: Singer part numbers 160985 and 161102 .
The lockstitch sewing machine, invented and developed in the 18th and 19th centuries, [10] [11] forms a stitch with two threads: one passed through a needle and another from a bobbin. Each thread stays on the same side of the material being sewn, interlacing with the other thread at each needle hole thanks to the machine's movement. [12]
Trade card, ca 1900. The White Sewing Machine was the first sewing machine from the White Sewing Machine Company. [1] It used a vibrating shuttle bobbin driver design. For that reason, and to differentiate it from the later White Family Rotary that used a rotary hook design instead, it came to be known as the "White Vibrating Shuttle" or "White VS".
It is a back-and-forth stitch used where a straight stitch will not suffice, such as in reinforcing buttonholes, in stitching stretchable fabrics, and in temporarily joining two work pieces edge-to-edge. When creating a zigzag stitch, the side to side motion of the sewing machine's needle is controlled by a cam. As the cam rotates, a fingerlike ...
