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.
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]
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 ...
The button is located on the improved shuttle frame, Singer part number 54507, which can be retrofitted onto older model 27 and 28 machines. The bobbin winder is mounted high on the pedestal, where a small rubber tire occupying its pulley makes contact with the motor belt.
A shuttle is a tool designed to neatly and compactly store a holder that carries the thread of the weft yarn while weaving with a loom. Shuttles are thrown or passed back and forth through the shed , between the yarn threads of the warp in order to weave in the weft.
The principal advantage of the Northrop loom was that it was fully automatic; when a warp thread broke, the loom stopped until it was fixed. When the shuttle ran out of thread, Northrop's mechanism ejected the depleted pirn and loaded a new full one without stopping. A loom operative could work 16 or more looms whereas previously they could ...
In 1851 Wilson patented his famous rotary 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. '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 ...
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".
