One of the chief features of Vaucanson’s machine was a pierced cylinder which, according to the holes it presented when revolved, regulated the movement of certain needles, and caused the threads of the warp to deviate in such a manner as to produce a given design, though only of a simple character. Jacquard seized upon the suggestion with avidity, and, with the genius of the true inventor, at once proceeded to improve upon it. At the end of a month his weaving-machine was completed. To the cylinder of Vancanson, he added an endless piece of pasteboard pierced with a number of holes, through which the threads of the warp were presented to the weaver; while another piece of mechanism indicated to the workman the colour of the shuttle which he ought to throw. Thus the drawboy and the reader of designs were both at once superseded. The first use Jacquard made of his new loom was to weave with it several yards of rich stuff which he presented to the Empress Josephine. Napoleon was highly gratified with the result of the inventor’s labours, and ordered a number of the looms to be constructed by the best workmen, after Jacquard’s model, and presented to him; after which he returned to Lyons. There he experienced the frequent fate of inventors. He was regarded by his townsmen as an enemy, and treated by them as Kay, Hargreaves, and Arkwright had been in Lancashire. The workmen looked upon the new loom as fatal to their trade, and feared lest it should at once take the bread from their mouths. A tumultuous meeting was held on the Place des Terreaux, when it was determined to destroy the machines. This was however prevented by the military. But Jacquard was denounced and hanged in effigy. The ‘Conseil des prud’hommes’ in vain endeavoured to allay the excitement, and they were themselves denounced. At length, carried away by the popular impulse, the prud’hommes, most of whom had been workmen and sympathized with the class, had one of Jacquard’s looms carried off and publicly broken in pieces. Riots followed, in one of which Jacquard was dragged along the quay by an infuriated mob intending to drown him, but he was rescued.
