APPARATUS FOR DYEING, 84C.

SPECIFICATION forming part of Letters Patent No. 552,638, dated January 7, 1896.

Application filed February 28, 1895. Serial No. 540,120. (No model.) Patented in Germany August 9, 1893, No. 74,984=,- in Austria March 81, 1894, No. 58,754, and in Hungary March 31,1894, No. 94,751.

To all whom it may concern:

a Be it known that I, LUDOLF FRoTsoHnR, a subject of the King of Saxony, and a resident of the city of Zittau, in the Kingdom of Saxony, Germany, have invented certain new and useful Apparatus for the Treatment of Spun or WVoven Fibrous Materials with Dyeing, WVashing, Bleaching, Mordanting, and other Liquids or Solutions, (for which I have obtained a patent in Germany No. 74,934, dated August 9, 1893; in Austria No. 58,754, dated March 31, 1894., and in Hungary No. 94,7 51, dated March31, 1894;) and I do hereby declare that the following is a full, clear, and

exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an apparatus for the treatment of spun or woven fibrous materials with dyeing, washing, bleaching, mordanting, and other liquids or solutions; and the object of my invention is, first, to provide means for forcing ordrawing liquids, atmospheric air, or steam, as maybe required, through the fibrous material by placing a liquid container in communication through pipes either with a vacuum-forming apparatus, or a compressed air-vessel, or a steamgenerator; secondly, to perform the dyeing process in such a way that the material under treatment is dyed equably throughout, which end is obtained by forcing and drawing through the material the dyeing liquid in a state of equal strength or concentration, not only from the outside thereof inward, but also in the contrary direction from the inside thereof outward; thirdly, to treat the fibrous material with different liquids or so lutions one after another by drawing firstone liquid from a trough or tank through the material into theliquid-container and discharging it and then drawing another liquid from another trough or vessel into the liquid-container, from which said liquid isforced through the material into the first-mentioned trough or tank.

I attain the above object by means of the apparatus shown in the accompanying drawings, in which t Figure 1 is a part sectionalfront elevation thereof Fig. 2, a part sectional side elevation. Fig. 3 is a detail view, on an enlarged scale, showing the manner in which cop-spindles may be fixed on a material-carrier5 and Fig. 4, a detail view, on an enlarged scale, of a material-carrier with woven goods wound thereon.

d is a liquid or solution container which is in connection by a valve on and pipe m with a vacuum apparatus 1), and by a valve 12 and pipe n with a compressed-air reservoir (compressor) o.

a is an air-pump 6, Fig. 2, a vessel for supplying through pipe t' and valve 8 auxiliary or additional liquid to the liquid-container d; 0, a steam-pipe fitted with a valve 0.

f is an open trough or tank.

g is a hollow cylinder, which is suspended in the trough f and serves for the reception of the goods to be treated. Said cylinder, which is mounted so as to be readily removable, consists, according to the nature of the goods to be treated, of a perforated hollow Warp-beam, Fig. 4, upon which all kinds of spun or woven goods may be wound, or of a pipe in which perforated hollow spindles for the reception of cop-bobbins,Fig. 3,are so fixed that the interior of the spindles is in communicationwith the inside of the pipe 9. The inside of the material-carrier is in communication with the liquid-container at through stuffing-box j ointed-pipe connections 1).

h are disks mounted upon the ends of the material-carrier g and serving as wheels for moving the latter to and from the trough, and also protect the cop-spindles from injury when this movement is being eifected.

In commencing operations the materialcarrier 9, withthe goods to be treated upon it, is placed in the dotted-line position g, Fig. ,2. The air is withdrawn from it by opening the valvesm and q, and then, after closing valve on, steamed through by opening valve in a pipe 70, which connects the liquid-container d with a steam-generator, the steam passing through the container cl, pipes 19, and the material-carrier. The latter is then lowered upon its stuffing-box joints 1) into the trough f and charged with a liquid or solution while the container cl contains air only. The valve min the pipe m leading to the vacuum apparatus is then opened and the air withdrawn from the container d, pipes 19, and carrier in consequence of which liquid is drawn from the trough through the mate rial to the carrier and thence through the jointed pipes 19 into the container d. In order to force the liquid back again into the trough f valve on is closed, and according as the'process is to be a cold or a hot one either valve 11 in the pipe leading to the compressor 6 is opened to admit compressed air, or valve 76 in the pipe leading to the steam-generator opened to admit steam, so that the liquid is driven from the container (Z and forced through the material under treatment in a contrary direction-that is, from the inside to the outside. This operation may be repeated several times until the material has been sufficiently treated with the liquid. In the use, for instance, of a dyeing liquid or solution the material does not in the j ustdescribed process take up the die equably throughout, as in the suction of the dyeing liquid through the material to the container d the outer portion of the fibers or threads first takes up the dye-stuff, and therefore the inner portion is dyed a lighter color, and when the dyeing liquid is forced back again it is not of sufficient strength or concentration for dyeing purposes. In order to avoid this disadvantage and to be able to dye the material equably throughout an auxiliary liquid or solution is supplied to the vessel e which is in connection with the c011- tainer d, and when an addition of fresh dyeing liquid is considered to be necessary the valves m and s are opened, whereupon the auxiliary liquid is drawn from the vessel 6 into the container cl, where by the action of steam supplied through pipe 0 it is intimately mixed with the previously-used dyeing liquid present therein. The liquid thus strengthened or resaturated is, in the manner above described, forced back again through the material into the trough f, the inner portion of the goods or fibers then being the first to take up the dye. After the dyestuff has been drawn and forced back several times in this way the material will be found to be dyed regularly throughout. The materialcarrier g is then raised from the trough f by turning it with the pipe connections on the stalling-box joints 1) into the position g, and the material thereon may be at once, for the purpose of drying or oxidizing it, subjected to a vacuum or to steam or atmospheric air pressure, as hereinbefore described.

Therefore in using this apparatus saturated dyeing liquid is first drawn through the goods from the outside to the inside and then again also saturated dyeing liquid forced through the goods from the inside to the outside, so that in the latter case the dye comes in contact with the inner portion of the same, which in the dyeing process is a very important advantage. Further by means of the apparatus the material may be treated with two different liquids at one operation. The process is then as follows: The carrier g, with the material to be treated upon it, is lowered into the trough f, and then, after opening the valve q, the container (1, by opening valve m, placed in communication with vacuum apparatus b, whereby the air is exhausted from the container d and the pipe connections 13 and liquid drawn from the trough f through the material from the outside thereof into the container d. When the material has been sufficiently treated in this way, valve 1 is closed and the liquid discharged from the container cl past valve i into a suitable vessel placed underneath. The second liquid or solution is then, after opening the valves or and s, drawn by suction or vacuum from the vessel 2 into the container (Z, and this latter then placed in communication with the compressor or with the steam-generator either by opening valve a or valve 70, as the case may be, whereby the liquid in the container dis, after opening valve q and closing valve i, forced by compressed air or by steam through the pipe connections p, the carrier g, and from the inside to the outside of the material into the trough f. In like manner a different kind of liquid,

a tannic-acid solution, for instance, may be supplied to the trough f, drawn through the material into the container d and discharged therefrom, then by means of a vacuum the container supplied from vessel c with a mordanting liquid to be forced through the material to the trough f, so that the material may be treated with two different liquids, one immediately after the other, the one being drawn from f to d and the other forced from cl to f.
