Transverse shuttle. Longitudinal shuttle 1846 by Elias Howe [1] Figure 5 from Howe's patent 4750, showing transverse shuttle 'K' in its race: 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]
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.
Later, to avoid litigation, he contrived a stationary bobbin, which became the permanent feature of the Wheeler & Wilson sewingmachine. [1] On the same day, August 12, Isaac M. Singer received his first patent on a transverse shuttle machine that became a
A new shuttle ejector button, invented in 1910, [12] eases removal of the shuttle for rethreading. The button is located on the improved shuttle frame, Singer part number 54507 , which can be retrofitted onto older model 27 and 28 machines.
1846 Transverse shuttle. The transverse shuttle is a method to drive a bobbin on a sewing machine so as to create the lockstitch technique. Transverse shuttles carry the bobbin in a boat-shaped shuttle, and reciprocate the shuttle along a straight horizontal shaft. As the earliest of bobbin drivers, the transverse shuttle was patented by Elias ...
In 1885 Singer built a new works at Kilbowie (designed by Robert Ewan [3]) which produced its first "vibrating shuttle" sewing machine, an improvement over contemporary transverse shuttle designs (see bobbin drivers). The Singer company began to market its machines internationally in 1855 and won first prize at the Paris World's Fair that year ...
In 1851 Wilson patented the rotating hook, which performed the functions of a shuttle by seizing the upper thread and throwing its loop over a circular bobbin containing the under thread. [2] This simplified the construction of the machine by getting rid of the reciprocation motion of the ordinary shuttle, and contributed to make a light tool ...
The article explains lockstitch formation in a hook-and-bobbin machine well (the animation is particularly helpful) but doesn't explain how a transverse shuttle machine makes this stitch. The sewing machine article is weak on this too. Transverse shuttle machines use a bobbin inside a shuttle on a long swinging arm.
