APPARATUS FOR USE IN DYEING 0R OTHERWISE ,TREATING WITH LIQUID, FIBBOUS MATERIALS IN SKEINS. r

Application med January 3, 1924. Serial No. 684,128.

To all whom it may comm:

Be it known that I, FREDERICK THoMAs WOOD, a subject of the King of Great Britain, residing at Coventry, in the county of Warwick, England, have invented new and useful Improvements in Apparatus for Use in Dyeing or Otherwise Treating with Liquid, Fibrous Materials in Skeins, of which the following is a speciication.

This invention consists in improvements in apparatus for use in dyeing, or otherwise treating with liquid, fibrous materials in skeins, the apparatus to which this invention relates being of the kind in which the skeins are supported on rods and other rods have such movem'ent relatively to the rst named rods as to lift the skeins and lower them onto the first named rods.

The object of this invention is to provide apparatus of this kind with-,means which will mechanically impart to the skeins, in a very eiiicient and expeditious manner, movements resembling those obtained when manipulating skeins by hand in dyeing, or otherwise subjecting skeins to the action of liquids, the mechanism which actuates the devices for giving such movements to the skeins being so arranged that no portions of the mechanism which move in contact with each other are in the bath. A further advantage of apparatus in accordance with this invention is that the skeins can be kept entirely immersed in the bath for any required length of time, and, if desired, until the dyeing is completed, which will be particularly beneicial when dyeing with vat, or sulphur, dyes. l

Although the apparatus in accordano with this invention can be used for treating skeins with liquids other than for dyeing, I will, for simplicity of description, presume that the apparatus is to be used for dyeing.

According to this invention the second rod, or each second rod, is so shaped, or bent that two portions of thesaid second rod are approximately parallel to one another and to the stationary rod, the said second rod being connected at the end of one portion with means by which motion is given to the said second rod such that the other portion has movement around the first-named rod to alternately lift and lower the skeins in the vat.

These and other features of the invention I will describe, with reference to the accompanying drawing, which shows a construction or arran ement in accordance with this l invention which will explain how it may be performed, but the invention is not limited t counter-weighted ropes 2, or chains, or other suitable mean, passing over pulleys supported in any suitable way, a frame consisting of an upper part 3, and a lower part 4, which carries the stationary rods 5, from which the skeins (indicated at 6) are suspended, the said frames being connected by hollow posts 18. Near to, and above, the lower part 4, of the frame is suspended a beam 7, arranged transversely to, and midway of, the length of the stationary rods 5, and carrying bent rods 8, corresponding in number to the stationary rods 5, from which the skeins are suspended. The said bent rods 8, extend, in each case, from each side of the beam 7, :along parallel, or approximately parallel,VY to the corresponding stationary rod. The said beam 7 is suspended by rods 9, from crank-pins 10, carried by discs 11, which can be driven by worm and worm-wheel as indicated at 12, (or other suitable gearing) from an electric, or any other suitable motor 13. The skeins are suspended in their lowered position from the stationary rods 5, and the corresponding bent rods 8 also pass through the loops of the skeins to lift them from, and lower them onto the rods 5.

If desired the lower loops of the skeins can pass round rods 14, carried by a lower beam y15 suspended from the frame above by counter-weighted ropes indicated at 16, (or chains, or other suitable means) which can be attached to the upper ends of guiding bars 17, ixed at their lower ends to the said lower beam 15, and guided in the hollow posts 18, which connect the upper and lower parts, 3 and 4, of the frame. These extra rods 14 keep the skeins well down in the dye liquor and, being suspended as described,

the said rods can be raised when the skeins have become wet enough to remain properly down in the liquor and then the said extra rods 14 will not interfere with the proper action of the aforesaid bent rods 8.

When the 4apparatus is in o eration with the skeins suspended from t e stationary rods 5, and with the bent rods 8 within the upper loops of the said skeins, as these bent rods 8 are caused, b the gear aforesaid, to describe circular pat s within the said loops, as indicated by the arrows in Figure 1, the portions of the bent rods 8 extending along one side of the stationary rods 5, revolve around the said stationary rods and raise the skeins from oil'l the said stationary rods and bring another portion, or fresh loop, ol the skeins above the said rods and then lower this other portion onto the rods 5, and

so on as long as is required, the skeins being consequently practically equally submitted to the action of the dyeing liquor throughout their length.

The bent rods 8 are shown in different positions in Figures 1 and 2.

-To prevent the skeins from becoming accidentally moved along and from the rods the bent rods 8 may be provided with stops 8, (see also Figure 3) constituting guards,

these stops, or guards, being preferably arthe upper side of the portions of the said rods projecting from the supporting beam. The said bent rods 8 are preferably supported from their beam 7 by being provided with saddle-pieces 8", which straddle the said beam.

If desired, the outer end of each lower rod 14 can be bent downwards in order to assist in keeping the skeins in their proper position. A gearebox can, if desired, be arranged between the electric motor 13 and the discs 11 to enable the speed with which the discs are rotated to be varied as may be required. l

What I claim is 1. Skein treating apparatus, `comprising stationary rod means for supporting the skein in a vat, and movable rod means .ro-

tatable around the stationary rod means to alternately lift and lower the skeins with respect to said stationary rod means, said movable rod means comprising portions parallel to each other and to the stationary rod means, together with means connected to the movable rod means for causing portion thereof to travel around the stationary rod means, substantially as described.

2. The combination with the construction specified in claim 1, of means arranged below the stationary rOd and within the skein loop, for holding the skein down within the liquor. i

3.- The combination with the construction specified in claim 1, of means on the mowable rod for holding the skeins in position thereon. i

4. The combination with the construction specified in claim 1, of means completely and constantly located above the liquor in the vat, for lifting and lowering the skeins and their supports with respect to the vat.

5. Skein treating apparatus, comprising spaced stationary upper and lower members embraced within the skein, together with an `independent member adapted to travel around one of said stationary members and intermittently engage the skein to cause its step by step displacement around the vstationary members.

6. Skein treating apparatus, comprising spaced stationary upper and lower members embraced within the skein, together with an independent member adapted to travel around the .upper stationary member and intermittently lift the skein from said upper member, advance the skein with respect thereto and lower the skein upon said member whereby the skein is advanced'step by step around the said stationary members.

In testimony whereof I have signed my name to this specification in the presence ot two subscribing witnesses.

FREDERICK THOMAS WOOD.
