the Exposition of National Industry at Paris in 1801, and obtained a bronze medal. Jacquard was further honoured by a visit at Lyons from the Minister Carnot, who desired to congratulate him in person on the success of his invention. In the following year the Society of Arts in London offered a prize for the invention of a machine for manufacturing fishing-nets and boarding-netting for ships. Jacquard heard of this, and while walking one day in the fields according to his custom, he turned the subject over in his mind, and contrived the plan of a machine for the purpose. His friend, the manufacturer, again furnished him with the means of carrying out his idea, and in three weeks Jacquard had completed his invention.
Jacquard’s achievement having come to the knowledge of the Prefect of the Department, he was summoned before that functionary, and, on his explanation of the working of the machine, a report on the subject was forwarded to the Emperor. The inventor was forthwith summoned to Paris with his machine, and brought into the presence of the Emperor, who received him with the consideration due to his genius. The interview lasted two hours, during which Jacquard, placed at his ease by the Emperor’s affability, explained to him the improvements which he proposed to make in the looms for weaving figured goods. The result was, that he was provided with apartments in the Conservatoire des Arts et Métiers, where he had the use of the workshop during his stay, and was provided with a suitable allowance for his maintenance.
Installed in the Conservatoire, Jacquard proceeded to complete the details of his improved loom. He had the advantage of minutely inspecting the various exquisite pieces of mechanism contained in that great treasury of human ingenuity. Among the machines which more particularly attracted his attention, and eventually set him upon the track of his discovery, was a loom for weaving flowered silk, made by Vaucanson the celebrated automaton-maker.
Vaucanson was a man of the highest order of constructive genius. The inventive faculty was so strong in him that it may almost be said to have amounted to a passion, and could not be restrained. The saying that the poet is born, not made, applies with equal force to the inventor, who, though indebted, like the other, to culture and improved opportunities, nevertheless contrives and constructs new combinations of machinery mainly to gratify his own instinct. This was peculiarly the case with Vaucanson; for his most elaborate works were not so much distinguished for their utility as for the curious ingenuity which they displayed. While a mere boy attending Sunday conversations with his mother, he amused himself by watching, through the chinks of a partition wall, part of the movements of a clock in the adjoining apartment. He endeavoured to understand them, and by brooding over the subject, after several months he discovered the principle of the escapement.
From that time the subject of mechanical invention took complete possession of him. With some rude tools which he contrived, he made a wooden clock that marked the hours with remarkable exactness; while he made for a miniature chapel the figures of some angels which waved their wings, and some priests that made several ecclesiastical movements. With the view of executing some other automata he had designed, he proceeded to study anatomy, music, and mechanics, which occupied him for several years. The sight of the Flute-player in the Gardens of the Tuileries inspired him with the resolution to invent a similar figure that should play; and after several years’ study and labour, though struggling with illness, he succeeded in accomplishing his object. He next produced a Flageolet-player, which was succeeded by a Duck—the most ingenious of his contrivances—which swam, dabbled, drank, and quacked like a real duck. He next invented an asp, employed in the tragedy of ‘Cléopâtre,’ which hissed and darted at the bosom of the actress.
Vaucanson, however, did not confine himself merely to the making of automata. By reason of his ingenuity, Cardinal de Fleury appointed him inspector of the silk manufactories of France; and he was no sooner in office, than with his usual irrepressible instinct to invent, he proceeded to introduce improvements in silk machinery. One of these was his mill for thrown silk, which so excited the anger of the Lyons operatives, who feared the loss of employment through its means, that they pelted him with stones and had nearly killed him. He nevertheless went on inventing, and next produced a machine for weaving flowered silks, with a contrivance for giving a dressing to the thread, so as to render that of each bobbin or skein of an equal thickness.
When Vaucanson died in 1782, after a long illness, he bequeathed his collection of machines to the Queen, who seems to have set but small value on them, and they were shortly after dispersed. But his machine for weaving flowered silks was happily preserved in the Conservatoire des Arts et Métiers, and there Jacquard found it among the many curious and interesting articles in the collection. It proved of the utmost value to him, for it immediately set him on the track of the principal modification which he introduced in his improved loom.
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.
