Abstract: 6731. Lake, H. H., [Mattei, D.]. March 23. Dyeing. -Relates to apparatus of the kind described in Specifications No. 12,466, A.D. 1893, and No. 17,173, A.D. 1897, for dyeing card slivers or other textile fibres, and consists of improvements in means for impregnating the material with water or dyes, in wringing-apparatus, in dipping - apparatus, in conveying and steaming apparatus, in stop-motions, and in the arrangement of these elements to operate as a whole. When the material is to be impregnated with water or other liquids which may be used in large quantities, it is passed through the injector shown in Fig. 6, in which a perforated roller 1 containing a water-supply pipe 10 is surmounted by a casing, which is pivoted at 9 and is pressed upon the roller by weights 8. The material is freed from air by steam from the chamber 5, and then saturated by water from the pipe 10 and chamber 6. When expensive dyes are employed, the impregnating- apparatus shown in Fig. 8 is employed. In this the air is expelled from the slivers by steam as they pass between a perforated roller 12 and the chamber 13, the exit from which is arranged beneath the dye in the trough 11 to avoid access of air to the slivers, and the slivers are dipped into the dye by a cylinder 14 formed with projecting bars 15, whence it passes to a guide-roller 16 which delivers it to the wringing-rollers. The slivers next pass into dipping-apparatus shown in Fig. 10, in which they travel first under a cylinder 22 fitted with projecting bars and then over a perforated or fluted roller 23 upon which bears a wringing-out roller25. The roller 22 is mounted in a trough 19, which is pivoted at one end at 26 and suspended at the other end by springs 27, which prevent breakages in case the sliver becomes entangled around the cylinder 22 or 23. A tube 28 on the journal of the cylinder prevents floating fibres from winding on the journal. The level of the dye in the trough is maintained by a float 20 carrying a projection 20<x>, Fig. 18, which engages with an opening in the end of the pipe 20<1> and controls the supply from a reservoir. On leaving the cylinder 23, the slivers are delivered by a reel, in regular layers or folds, upon the belt 31 of the conveying-device shown in Fig. 12, which is provided with a cover 36 and is heated by steam. The belt is provided with slats which travel in recesses in the vessel 29. Fig. 1 represents the general arrangement of the machine, the apparatus being set up, for example, in five sections I, II, III, IV, and V, of which the second, third, and fourth are alike, each comprising the parts already described. The first section contains also a stop-motion, Fig, 16, which puts the whole section out of action should a sliver be broken, as follows :-Normally, the tension of the sliver on the lever 53, which is pivoted at its middle, supports the weight of a plate 54 suspended from the other end of the lever. But, when a sliver breaks the plate 54 falls and comes into contact with a blade 55, which on revolving shifts a lever 56 towards the left, thereby removing a stop 57 and allowing a weight 58 to draw down the starting-lever. The successive sections are also fitted with spring clutches which yield and throw the corresponding sections out of action when undue resistances arise. The last section (V) contains only wringing - apparatus, water jets, and a winding-on apparatus comprising a core resting on two pulleys and provided with end guide-discs, one of which is detachable for removing the finished rolls of sliver. The slivers take a zig-zag path through the sections and the sets of collecting and conveying apparatus 40, 41, 42 and 43.
