APPARATUS FOR THE TREATMENT OF YARN PACKAGES WITH FLUIDS,

. Application filed November 20, 1925. Serial No. 70,390.

These improvements relate to apparatus.

for the liquid treatment of yarn packages by the passing therethrough under pressure of liquor with which they are to be treated, with subsequent extraction from the said packages of surplus liquor left therein by the passing of air through such packages under pressure. In the term pressure is deemed to be included any pressure above atmospheric pressure or any pressure below atmospheric pressure, i. e. vacuum.

The improvements have for object a very simple and efi'ective apparatus by which a considerable quantity of yarn may be treated in a short time without unnecessary handling, the apparatus being found very suitable for washing yarns wound on spools having a perforated yarn bearing surface with subsequent extraction of wash water therefrom.

According to the improvements a rotary cavity plate is mounted upon a horizontal axis in a liquor tank, with means for mountin g the yarn packages on the cavity plate in such a manner that direct access from the tank to the cavity plate interior can only be I had through the yarns, and a liquor pump is arranged to pass liquor through the yarns into the cavity plate and back to the tank. A vacuum pump is also connected to the cavity plate interior, so that liquidand air treatment of the yarns may take place successively without removing the packages from the cavity plate, and the rotation of the latter allows removal of treated packages and the substitution therefor of fresh ones for treatment as the cavity plate ro-- tates, nontime being lost by the placing in position of fresh batches of yarn for treatment.

modifications will now be fully described with reference to the accompaying drawings, wherein Figure 1 is a longitudinal section of one form of the apparatus...

Figure 2 is a cross section of same taken on line 2-2 of Figure 1.

Figure 3 is a detail of a spindle showing The improvements in two convenientpump'of any ordinary known type and a a branch from such pipe communicates with a rotary liquor pump 13, between which pump and the interior of tank communication is established by the pipe 14. Valve is fitted upon the branch pipe.

Upon the hollow bearing is rotatably mounted the cavity plate 16 the interior of which is hollow, having the bosses 17, the

plate being positioned upon the bearing 12 by the end flange 10 on one side and the annular block 9 upon the other. In the bearing are formed circumferentialorifices 18 givlng communication at any point in the rotation of the plate 16, between the interior of the latter and the interior of the bearing 12, thus rendering the interior of the cavity plate 16 open to the pump 13 and to the pipe 19 leading to the air pump.

The face of the cavity plate is formed with bosses 20 having tapped holes 21 to any convenient number each formed on a radius line of the plate, and adapted to receive the neck of a spindle 22 as shown in the detail Figure 3, a quick screw thread being formed on the said neck. The spindle has a circular base plate 23 fixed thereon and the body of the spindle may be hollow and perforated or it may be solid and fluted as shown in the detail Figure 3 and in broken section Figure 1. Upon this spindle are mounted yarn packages 24the packages shown are wound upon flanged bobbins 25 with washers 26 placed between two adjacent flanges when the bobbins are in position on the spindle 22-and when a spindle is filled the whole" may be put under compression by the nut 27 on the screwed end 27Lto ensure a fluid tight joint between the said adjacent flanges.

The cavity plate 16 is fitted circumferentially with the toothed annulus 28 forming a worm wheel which meshes with a worm 29, on a worm shaft 30 driven in any convenient manner and at a conveniently slow speed.

Spindles t0 the desired number having been charged with bobbins, the cavity plate is rotated and as an orifice 21 comes to the highest point a spindle is screwed thereinto, each orifice 21 being thus fitted with a spindle 23 as the cavity plate 16 rotates. hen the plate is fully charged, or during the charging, the tank is filled with the wash water up to the level 31 and the pump 13 started.

The water then circulates through the yarn packages 2 1 into the cavity plate 16 through the orifices 18 in the bearing 12 and thence to the pump 13 to be returned to the tank, this circulation being kept up as long as necessary and reversed if desired. The washing being complete the pump 13 is stopped, and the water allowed to run to drain through pipe 8. The air pump is then started and air is circulated by means of pipe 19 through the yarns in a similar manner to that by which the liquor was passed through them. Whilst this extraction is proceeding, the cavity plate 16 is stopped. The extraction of surplus moisture being completed, the vacuum pump is stopped and the cavity plate again rotated, each spindle being removed as it arrives at the highest point and a fresh one substituted for treatment.

The cavity plate being charged thus with new spindles, fresh wash water is led into the tank and the whole process repeated.

In the modification shown in Figures 4 and 5, the parts are the same as shown in the figures hereinbefore described and referred to, but with this exception that the bearing 12 has two orifices with three chambers formed by the

partitions

32 and 33, the pipe 11 also being divided by corresponding partitions as shown. Further, the cavity plate 16 is formed with segmental chambers 3-1 with dividing walls 35 each segment being open to the pipe chamber 36, or the further pipe chamber 37. as the cavity plate 16 rotates, and each orifice 21 is formed in the front wall of a segment 34. One of the pipe chambers, 37. communicates with the liquor pump 13, another 36, communicates with the vacuum pump by way of pipe 19. The liquor in the tank being filled up to level 38 only, and the cavity plate rotating, it will be seen that for a little more than half the circuit of the plate 16 the yarn packages 24. are being treated w h liquor, but as they rise with the plate 16 each segment 34 becomes closed to the liquor pump and open to the air pump through the pipe chamber 36. Continued motion of the cavity plate brings any such segment out of communication with the air pump and into a position where its segment registers with the are 39 Figure 5, of the surface of pipe. Thus, the spindles will succe sively pass through liquor treatment and air treatment and ultimately arrive at a point where they can be removed and substituted by fresh ones, the treatment, and the rotation of the cavity plates thus being continuous.

Where any liquor employed, or the material washed out of the yarns, may have a corrosive action any parts in contact with the liquor may be of non-corrosive metal.

The liquor level in the modification of Figures 4 and 5 necessarily only comesto the level of the partition 32 of the bearing 12. The tank may therefore be only the height as shown in Figure e at that end opposite to the cavity plate, and a circular bearing plate 39 be rotatably fitted within the tank on a bearing 40. The said plate is slotted radially as shown at 41 in the detail Figure 6, and the screwed end 27 of a spindle 23 will rest in a slot, being secured by friction therein by a nut 42 screwed up tightly to bear against the plate 39. Except where the length of a spindle and its load of yarns make it advisable to use such an end supporting plate it may be omitted.
