The dyeing of textile fabrics . r lowered by a hydraulic ram in the raised, the front ends of the reels are free to betilled ^vith yarn ; when lowered, the hanks are imniensedin the dye liquor. By means of the pulleys at c, the largecog-wheel b is made to revolve in alternate directions,and the motion is transmitted to the cog-wheel of thereel immediateh behind. This alternating motion is Chap. XTL] MACHINERY FOR COTTON YARN. 253 necessary in order to keep the yarn well opened out,and to prevent it from becoming entangled. When the cotton yarn is in the chain form, beingintended for warps, a machine similar to that representedin Fig. 51 is employed. In its simplest form—namely, as a single-box machine—it consists of a rectangular wooden dyebeck a, fitted above and below with a seriesof wooden rollers, and at tho end with a pair of squeezingrollers. The machine represented is a two-box machine,and is simply a duplication of that just described. Sixor eight warp-chains g, separated by the guide-pegs at. Fig. 51.—Warp-Dyeing MacMno. H, are passed side by side through the two boxes A andB in the direction indicated. The squeezing rollers c dprevent as much as possible the liquor in a from beingdrawn over by the warps into b, which contains a dif-ferent liquid. As the warps pass out of the machine,the squeezing rollers E f remove excess of liquid tofacilitate the subsequent drying. At J the warps areagain separated by guide pegs, and withdrawn from themachine by the reel k. The steam pipes l l serve forheating the solutions employed. Some machines { used for dyeing logwood-blacks) have as many assix boxes, each box being filled with a different liquid,which may serve for mordanting, dyeing, washing, & whole machine is specially arranged to make theseveral operations continuous. 254 DYEING OF TEXTILE FABRICS.
