Bobbin (right) and bobbin case for a shuttle hook sewing machine, introduced by Singer for the "Improved Family" model in 1895 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.
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 ...
