Abstract: 17,083. Rhodes, J. Aug. 14. Dyeing.-Wool, yarn, and other fibrous material are prepared, dyed, and otherwise treated with liquids in the compartments of an apparatus in which the treating-liquid is caused to rise up side passages and is poured on to the material by the action of baffle-plates so arranged that the compartments may be used separately or simultaneously. A tank 2 is preferably divided by a longitudinal partition 3 into two compartments 4, 5, which are subdivided horizontally into two cages 7, 8 by removable floors 9, 10 made in sections consisting of grates. The grates, of which the bars are preferably of triangular cross-section, carry the material to be treated. When hanks are to be treated they are supported on transverse revolving carriers 41, the middle horizontal partition being omitted. One end 42 of each carrier is made square to fit corresponding holes 44 in worm and spur wheels 47, which gear with and are driven in pairs by worms 51 on a shaft 52 on the top of the central partition 3. The other ends 57 of the carriers 41 revolve in open bearings 55 on the side walls of the vat 2 so that the carriers 41 are easily removable. In operation the treating-liquid is projected up the side passages 17, formed by longitudinal partitions 20, by the action of steam-pipes 32, or pumps &c. Fixed baffle-plates 35 are placed at the top of this passage, and horizontally-pivoted baffle-plates 27, actuated by means of vertical rods 30, are arranged at the top of the lower cage 8. If the movable plates 27 are placed vertically so as to close the corresponding longitudinal openings 25 in the partitions 20, the liquid passes up to the upper baffle-plates 35 and is thrown out over the material through corresponding openings 26. When, however, the lower cage 8 only is to be used, the movable plates are placed approximately horizontal, and the liquid is thrown out through the lower openings 25. The dye or other liquid is supplied through perforated pipes 60 and is regulated by a ball cock &c. The liquor partly fills the bottom of the tank and is discharged through openings 62 closed by plugs 63 operated by rods 64. Overflow pipes &c. are provided. The partition 3 may extend only half-way up, forming one large upper and two smaller lower compartments, the driving-mechanism for hanks being placed on one side of the tank 2. Or the partition &c. may be removed entirely. The apparatus is preferably lined with some such material as wire netting. According to the Provisional Specification, the outer vat has an inner vat for containing the material, the liquor being circulated on all sides of this inner vat so as to fall on the material therein. It is also stated that the liquor is preferably delivered through sprinklers placed over the top of the apparatus, and that horizontal doors may be used below the sprinklers capable of sliding one over the other, to enable the dye liquor to concentrate itself at any part of the material or machine.
