` Application filed Octoberl 23, 1924. Serial No. 745,488.
To all 'whomt mayconcem:
Beit known that- I, BERNHARD KARL THIEs, a. citizen of the German Republic, and residing at Coesfeld, in I Ve'stphalia, Prussia, Germany, 4have vinvented certain new-and useful Improvements in Dyeingv Apparatus (forlwhich I have filed applicaf t1ons in Germany on March 30, 1921, and in Great Britain 'on September 18, 1924), of which -the following is a specification. l
For dyein and bleaching fabrics in light tones as uni ormly .as possible it has lalready been proposed to pass the bath alternately through two co-acting dyeing apparatus. 'If the pump be arranged to deliver directly to the dyeing apparatus, a certain quantity of the bath 1s always put in motion and 1t is not possible, when the dyeing apparatus are used differently, 'to obtain the necessary equalization of the bath, that is, a uniform and thorough mixing of the dye bath and in consequence an equal uniform dyeing of the goods. In addition to this it is difiicult to obtainA the necessary .uniform 4mixture for dyeing light, one-coloured goods. 4
According to the present invention auxiliary vacuum vessels are used in conjunction with two co-actingdyeing apparatus, more particularly for dyeing with a circulating' bath, which vessels contain the requisite reserve quantity of bath for maintaining the e ualization of the bath and the contents of w lich are` drawnA into the mixing circulation between the two dyeing apparatus by the outflow pipe of cach dye vat acting as an ejector on the contents of the corresponding auxiliary vacuum vessel and carrying it along tothe auxiliary vacuum vessel of the other dye vat. The ejector action causes a thorough mixing and an additional. mixing is effected at the entrance into the auxiliary vaccum vessel `ot the other dye vat. This will cause the ycolour to be perfectly uniform4 and it is possible to dye large quanti- ,ties of goods without faults.
For obtaining the ejector action, the out-A flow pipes from the two dyeing vats are each assed through an auxiliary vacuum vessel' luto pipes of a larger diameter, the outflow pipes bemg unsupported within the larger pipes and having their ends open.
The outer pipes are connected each at the back to the correspondmg auxiliary vacuum vvessel and lead in opposite directions, that is, in the direction of flow, through connecting pipes of a smaller diameter each to the' apparatus. If a stop-cock be providedjin au 4 upper vacuum equalizing pipe of the two auxiliary vacuum vessels and a stop-cock in each of the lower connecting pipes between the two auxiliary vacuum vessels, it is possible, when treating small quantities of goods, to use each side of the total apparatus, consisting of the dyeing vat and the corresponding auxiliary vacuum vessel with the pump, by itself, in which case, when the stop-cock is closed, the bath can not longer flow out of the pipel of larger diameter, referred to, surrounding the` orifice of the outflow pipe, from the dyeing vat into the auxiliary vacuum vessel of the other dyeing apparatus, but will flow in the opposite direction within the pipe of greater diameter and back to the auxiliary vacuum vessel, from which the `bath had previously been conveyed by the pump to the dyeing vat.
By'this means each side closed on itself.
In the accompanying drawings a construcwill have been -tional example of the invention is shown,
Fig. 1 being a side elevation partly in section,
Fig. 2 a plan view and Fig. 3 a vertical section through two auxiliary vacuum vessels. .f l
1 and 1a are the dyeing vats for containing the goods and 2 and 2a are the correspondging' auxiliaryvacuum vessels provided with sight gauges 2 'and '2" respectively. The vessels are 'connected at the top by an equalizing'lpipe 12 (Fig. 3) containing a stopcock 13 and are each provided with a lat- 5u to the dyeing vats 1 and 1.,. Connecting pipes 6 and 6a 'for the dyeing bath are -arranged between the vrespective fou'rway cocks 5 and 5, and the bottom of the vats l and 1...- The outflow pipes from the latter are marked 7 and 7,. The pipes 7 and 7., and the bends 8 and 8a lead through the corresponding auxiliary vacuum vessels 2 and v 2,. and, after passing good-s4 with eight racks,4
Vpared baths.
pipes vof greater diameter 9 and 9., which atter 'pipes are connected 4at the back to the'corresponding auxiliary vacuum , vessels 2 and 2,.. The other ends of the pipes 9 and 9 are connected to pipes 10 and 10,' of smaller diameter, which lead through stopcocks 11 and 11Il into the other auxiliary vacuum vessels 2 2.
The apparatus shown in the drawing is suitable for dealing with large quantities vof goods. 8, .9 and 10 andv 8,., 9, and 10.l
each represent an ejector. The bath flowing through 7 and 7a emerges at the orifice of the bend 8, 8,., and carries thebath along 'with it from the auxiliary vacuum vessel 2,
2u behindit, while mixing with it, and car- ,ries the mixture through 10,1 10,L into the other auxiliary vacuum vessel 2a, 2.
It has been found in ractical operati n that it is impossible to o tain exactly identical shades, when dyeing is effected successively under to dye simult-aneously -a thoroughly mixed through the goodcirculation, through -tlie passage,` of the bath through ejectors and, in consequence, an entirely uniform dye being obtained.
at-the same time, it,J is /possible' to build a large plant which if at all times lar e quantitiesA are to be dyed the same color. n order to Vbe able to utilize the plant also for smaller quantities, such as four-racks, without great loss of bath, the combination plant is built, which permits of economical operation in the dyeingdof large as well as small quantities of noo s. 1
b When small quantities are tobe dealt with each side is closed on itself, by closing tlie stop- cocks 13, 11a and 11. Thus, for instance, if only the` left-hand system is working the bath will flow from thepump 3 through 4 and 5 and 6 to the dyeing vat 1 and through 7 to the bend 8 and will emerge from the orifice of the latter, it cannot carry any bath along with it, but will turn back and flow .around the end ofthe bend 8 through the space between the end of the bend and the pipe 9 of larger diameter to the auxiliary vacuum vessel 2 and from the latter back to the pumpand so one. Perorated plates 15 and 15a 4in the auxiliary vacuum vessels have an equalizing action and prevent surging.v
out again, open into the A for enabling dye that is use of the same or newly Vpre.y Through the combination of the two dyeing apparatuses it is possible large quantity ofl the bath being the auxiliary vessel and by the two would be economical only s Thumb screws 16 (see Fig. 2) are providedi for effecting tight c osing of the ianged covers of the dyein vats 1 and 1.. In order to preventthe vormation of air pockets inthe vats 1 and 1., and facilitate a uinform dyeing of the whole of the goods, air' releasing ldevices 17 are mounted on the covers of the vats 1 and 1., and atthe beginning of vthe circulationv these air releasing evices 17 are open so that the air completely escapes and the dyeing apparatus is filled wholly with dyeing liquor.
lVhat I claim is: Y 1. Dyeing apparatus of the character described 'inc udingltwo dye vats, two auxiliary vacuum vessels, one of said vessels being directlyconnected with each of said vats, means for causing dye to pass from each ot said vessels into its associated vat, an outflow pipe leading from each vat into the ves- Sel associated with the'other vat, and means passing through oiie of 'said outflow pipes to take with it by .ejector action a vfurther supply-of dye from its own vacuum vessel into the other vacu- 2. Dyein apparatus of the character described inc uding two dye vats, two auxiliary. v-acuum vessels, 'one of said vessels being directly connected with each of said vat's, meansfor' causing dye to pass from U each of said vessels into its associated vat, To dye large quantities, with .eight racks pipes into the other vessel, each of the outflow pipes from the vat passing through the vessel associated with its own vat and terminating within the pipe of larger diameter connected therewith.
` 3. Dyeing apparatus as claimed in claim '1, further comprising an equalizing pipe .connecting .the twoivacuum vessels with one another-at .the top, means for closing said equalizing pipe, andmeans for diverting at will the dye in an` outflow ipe into the vessel associated with the vat rom which it has just issued.
4. Dyeing apparatus as claimed in claim 2, further comprising an equalizing pipe connecting the two vacuum vessels with one another at the top, means for closing said equalizing pipe, and means for closing the pipes leadingl away from the outer ends of the pipes of larger diameter.
In testimony whereof` I have signed my name to this specification.
