The subject of shedding, i. e., of opening the warp-threads to afford a passage for the shuttle, is so inseparably connected with the name of Jacquard, that attention is now carried to that wonderful invention evolved in the first few years of the present century, and by the use of which it may truly be said that anything can be woven as figure in a fabric that can be designed by the hand of man. It is as well adapted for the finest silks as for heavy carpets and figured velvets, and by an operation theoretically so simple as to excite wonder that it remained hidden until this age. Jacquard was a native of France and exhibited his machine complete in 1804, but so bitter was the opposition that the first machine was destroyed and burned. Its merits were clear, however, and reconstruction and general adoption in France followed soon after. It has since been applied not only for shedding but for every purpose where mechanical operations could be controlled by a pattern. In brief, this machine simply controls each warp thread separately by a cord having a hook attached. These hooks are arranged near the path of a reciprocating griffe or frame carrying cross bars, and are controlled, as to engagement with the bars, by a card perforated according to a pattern; thus any one or any number of threads can be raised at will. The dobbie controls harness frames each carrying a large number of warp threads; the Jacquard controls every thread separately. The greatly increased capacity of the latter machine is apparent. Thus a 1500-hook Jacquard will do the work of thirty dobbies of fifty jacks each. The hand-shuttle box mechanism of Kay’s time has developed into the machine operated as a sliding or revolving shuttle-box controlled by pattern devices, which, being added to a dobbie or Jacquard equipped loom within the last twenty-five years, presents the highest point of perfection attained in the textile art. In such looms the warp threads, arranged in any colors, may be raised at will collectively or individually, any one of ten or twelve different colored wefts may be introduced as desired, and combinations may thus be formed to produce designs of the most complicated nature.
