'. p DYEING APPARATUS.

Be 'it flinown that we, ALBERT. J. RAU and JULIUS-A. RAU,'CltlZ6I1S-0f the United States,

residing: at Clifton, New Jersey, have invented certain new and useful Improvements in Dyeing Apparatus, of which the 7 following is a clear, full, and exact description. a

This invention relates todyeing apparatus, and a principal object of the present invention is to provide very simple means for facilitating the passing and guiding of a web of material when the dye is being applied thereto. 1

In the preferred'form of the invention, a

- dye bath is employed and one of the objects of this invention is to provide improved means for facilitating the passage y of the dye material into the fibers of the web which is being dyed. 1

A further object of the invention is to provide a very simple construction which willfenable the web to behandled in a simple manner, and at the same time permit the development of an excess hydrostatic'pressureon one side of the web which assists the passage of the dye liquor through thefibers of'the fabric.

Further objects of the invention will pear more clearly hereinafter.

"The invention consists in-the generalcombination of parts and simplicity of details hereinafter described, all of which contribute to produce an efiicient dyeing apparatus} A preferred embodiment of our invention-will be particularly described. in the following specification, while the broad scope; of our invention willfbepointed out- 40 in the appended claims. p

In the drawings, Figure'l 1s a-front elevation of the apparatus embodying our invention; Fig. 2 is a longitudinal section,-

certa-inparts being broken away; Fig. 3 is a vertical cross-section through the appara-' tus further illustrating the lnvention; and

7 Figs. 4 and 5 show details.

' Referring more particularly to the parts, we preferto apply the dye in the form of a dye'liquor, and this is preferably accom- Specification of Letters Patent. Application filed March 4, 1914. Seria1 No. 822,359.

vat; holdsthe roller 8 in contact with the drum iiso that the drum rotates it and the roller turn rotates the delivery-roll 14 in a idirectionto wind up the web upon it. The l'preferred means for enabling the rolls 13 Patented Aug. 25,1914.

preferably formed of end rings 5 connected by. a cylindrical body 6, preferably consisting of a Wire screen or similar material.

\Veprovide means for guiding the web 7 of the material to be dyed around the ex- 7 teriorof this' drum so that it comes in contact with the dye bath in the vat. This guiding means preferably consists of two rollers 8 and 9, the axles 10 of which are preferably supported at the ends of hanger InFig. 3, we have illustrated the web 7 as jpassi-ng'from a supply-roll 13 of material gto'be dyed, and the web 7 passes around the inner face of the roller 9 and thence passes around the drum, being guided from the drum by theinner face of the roller 8 and 'thencebeing wrapped'upon a delivery-roll 14. It should be understoodthat each of ;the rolls 13 and 14-may 'act as delivery or gsupply'rollp The roll which is acting as a fsupply-roll-is preferably held upon a fixed axis in elevated position, while the receiving 'or delivery roll such as the roll 14, preferably rests on the upper face of its correr'sponding'guide-roll such as the roll 8. Now

by asimple rotation of the shaft, the Web 7 ;.will, be'drawn off from the supply-roll 13 passed around on the underside of the revolving drum and then guided out of the The weight of the delivery-roll 14 and l to be-operatedfin this 'Way consists substantially of supporting arms 15 correlsponding to each roller and rigidly attached to'shafts-16, Any suitable means may be iprovided for counterweighting the rolls, for

which purpose the shafts 16 may be pro- **vided with segments 17 meshing with pinions 18, which-pinions are rigid with counterweight" levers 19. These levers are provided" with adjustable counterweights 2O which-can be;hung. at different points on the lever, to compensate for differences in weight'of goods, or removed entirely if necessary. The counterweight levers 19 are slightly depressed. When one of these rollers- 1s guiding the material onto the drum, the other is guiding it off of the drum.

preferably provided with clamping devices 21 which cooperate with slotted quadrants 22 so as to enable the arms 15 to be clamped if desired, in an elevated position and also enabling the arms to be freely movable up or down when the clamping device 21 is loose. which is receiving the web tohave its axle laterally movable, and this is desirable because as the roll turns, the layers of web accumulate upon it and automatically'raise the roll axis and the arms carrying the rolls. The rising ofthe delivery roll acts to move the counterweighted lever in opposite direction so that increased power is exerted by said lever and the counterbalancingeffeet automatically maintained. It will be evident that if the delivery-roll 14 is counterweighted at all, the counterweight should be very light so that there is always some weight on the roll 8 tending to bring about a good frictional contact insuring the proper rotation of the delivery-roll in winding the web upon it. The counterweights are particularly useful when a heavy supply-roll is being raised'on its arms 15 into a convenient position to facilitate the delivery of the web onto the drum. It is evident also that the pressure of the roll 14 on the roll 8 tends to raise the supply guide-roll 9 out of contact with the drum. In order to facilitate the rotation of the rolls 8 or 9 from the drum 3, we prefer to provide the end rings 5 of the drum with grooves to receive bearing rings 5 of rubber or similar material having a good traction effect. Beyond the heads 2 the vat is formed with false heads 23, and the spaces between these false heads and the heads 2 form conduits 2 1 to facilitate the circulation of the dye liquon.

While the apparatus described above can i be used simply to pass a web through a I bya shaft 27 and mounted in openings 28 bath in which the drum is immersed, we prefer to facilitate the dyeing apparatus by means of an excess of the hydrostatic pressure on one side of the web, and we prefer to accomplish this by withdrawing the dye liquor constantly from the interior of the drum'and returning it to the exterior. This is preferably accomplished by providing openlngs 25 in the heads 2v preferably below theshaft 4,,and the dye liquor is drawnoutwardly through these openings in the direction of the arrows in Fig. 2, by means of impellers or circulating wheels 26 carried in .the heads 2. The impellers in one' end ofv the vat are of opposite pitch from those of the opposite end so that at both ends of the'vat the apparatus operates to withdraw the liquor from the interior of the drum.

combination, a vat for the dye-bath, a drum As the heads 2 are very close to the ends ofthe drum, this circulation of the dye I liquor produces. a slight excess of hydrostatic pressure ongthe outer side of the drum This arrangement enables the roll' which assists in producing a flow of the dye liquor through the fibers of the web and renders the dyeing operation more efiective.

In using the apparatus the web to be dyed is run from one roll around the drum and is wrapped upon the opposite roll, and after the opposite roll is filled, the web can be repassed in the opposite direction around the drum and back to the roll which, originally carried the web. This operation may be repeated as often as desired.

While the drum 3 may have an outer shell 6 of any suitable construction of reticulated material, it is preferred that a built up construction such as that shown in Figs. 1 and 5 be employed. spiders 3 are fixed rigidly on shaft 4, inside To this end, supporting' the drum, and said shell 6 is secured rigidly 1 to said spiders. Said built up screen construction comprises longitudinal bars or rods 6 attached to the rims of said spiders 3. On these rods 6 there is helically wrapped,

about the drum, a continuous fine wire 6* and then on this wire is laid an-envelop or inner covering 6 of coarse mesh wire gauze.

Overthis is placed an outer covering (5 of fine mesh wire gauze. gauze construction is that material can be dyed in one passage around the drum and there is no spotted effect produced. Also, in the specific embodiment, the wire gauze is supported from the interior spiders of the drum and not directly by them, so that the gauze screen is properly supported on that side toward which the hydrostatic pressure is exerted.

Although the apparatus has been described above with the idea that it is to be used in dyeing the goods, it is obvious that this apparatus may be used for charging the goods or for washing goods, or for other purposes.

It is understood that the embodiment of the invention described above is only one of I the many embodiments or forms the invention may take, and we do not wish to be limited in the practice of the invention nor in our claims to the particular embodiment disclosed.
