draw link

A connecting-link for railway carriages. draw-loom, s. Weaving : The draw-loom was the predece or of the Jacquard, and is used in figure weaving. The number of the heddles being too great to be worked by the feet of the weaver, the warp-threads are pa ed through loops formed in strings, arranged in a vertical plane, one string to every warp-thread; and these strings are arranged in separate groups, which are pulled by a draw-boy, in such order as may be required to produce the pattern. The groups are drawn by pre ure on handles, the required order being determined by reference to a design, painted on paper, which is divided up into small squares. A mechanical draw-boy has been contrived, to dispense with human a istance. It consists of a half-wheel with a rim grooved so as to catch into the strings requiring to be pulled down. The half-wheel travels along a toothed bar, with an oscillating motion from right to left, and draws down the particular cords required for the pattern. ( Knight .)
