The design became obsolete once the other bobbin driver designs were developed. [3] Shuttle from a transverse shuttle bobbin driver: Sometimes incorrectly called an "oscillating shuttle". Somewhat confusingly, the term "Transverse Shuttle" is usually used only to refer to a side-to-side motion of the bobbin. When moved in a front-to-back motion ...
Early vibrating shuttle designs inherited the boat-shaped shuttle used in transverse shuttle machines, where the bobbin is inserted from the open side of the "boat". In the 1880s, bullet shuttles became dominant. The bullet shuttle is long and slender, shaped like a bullet, with a pointed tip that is sometimes called the hook.
The feed motion was obtained by the two metal bars which are seen intersecting above the shuttle race. The lower bar, called the feed bar, had teeth on its upper face, and by means of a transverse sliding motion it moved the cloth, which was placed between the two bars, the desired distance, as each stitch was made.

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 ...
Long, narrow bobbins are used in early transverse shuttle and vibrating shuttle machines. These earlier movements were rendered obsolete by the invention of the rotary hook and the shuttle hook, which run faster and quieter with less air resistance. These shorter, wider bobbins are familiar to modern sewers, as the rotary/shuttle hook remains ...
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 ...
Knowing that such a machine would surely lead to patent litigation with his former partners who had bought out the patent for the vibrating shuttle, Wilson kept working, and developed a refined design which kept the bobbin stationary. He filed for patent, and the partners built their first production rotary hook machine the same year, selling ...
A consolidated rental car facility (CRCF) or consolidated rental car center (CONRAC) is a complex that hosts numerous car rental agencies, typically found at airports in the United States. The most important incentives for building consolidated facilities are greatly reduced traffic congestion in airport pick up and drop off areas and increased ...
