Judkins' lock-stitch sewing machine, 1851.

This is a copy of the original machine designed by Charles Judkins (1822-1864) and displayed at the Great Exhibition in 1851, where it was the only British sewing machine exhibited. Two American and two French sewing machines, including Thimonnier's, were also shown at the Exhibition. This industrial machine was intended to be power-driven by the belt pulley at the rear, but a handle has also been fitted. The chief interest attached to this machine is the high rate of sewing - 500 stitches per minute - attained at an early date.
