Singer bullet shuttle with bobbin exposed. 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 ...

The design was popularized in the White Sewing Machine Company's 'Family Rotary' sewing machine [9] and Singer's models 95 and 115. [10]
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
While a large majority of embroidery software is specific to machine embroidery, there is also software available for use with hand embroidery techniques, such as cross-stitch. Comparison of embroidery software
The most novel machine of this kind is the vibrating shuttle machine just produced by the Singer Manufacturing Company. In this case the shuttle itself consists of a steel tube, into the open end of which the wound reel is dropped, and is free to revolve quite loosely. Variation of tension is thus obviated in a very simple manner.
