Abstract: 1569. Parkes, B. A. Jan. 20. Hank type.-An apparatus for dyeing, bleaching, and similarly treating skeins of yarn, as well as draining the skeins after such treatment, comprises two parts, namely (1) an assembling and draining stand having devices for supporting and spacing yarn-carrying rods, and (2) a frame having members for engaging the rods, whereby they may be raised simultaneously from the stand and conveyed to the liquor vat, whereon the frame rests during treatment, and means for moving such members into and out of engagement with the rods. The stand, Figs. I and III, comprises standards 26 which carry a frame consisting of fixed longitudinal side members 27, 28, each having a series of notches 29 in which the rods 5 carrying the hanks 6 are inserted. A swinging gauge-bar 33, Fig. III, on arms 34, is turned into position, Fig. I, so that the ends of the rod 5 can be brought into abutment therewith, and so be correctly alined, during assembly; the bar 33 is turned out of the way, Fig. III, before the lifting-frame is brought into use. The lifting- frame comprises a cover 1, which rests on the edge of the vat 62, Fig. IV, when supporting the yarn in the vat, and underneath which are attached brackets 2. Pivoted to the brackets 2 are longitudinal supporting-members 3, 4, furnished with spaced sockets 9 to receive the ends of the rods 5, which can be swung inwards, Fig. IV, or outwards, Fig. III, under the action of a shaft 14, rotatable by hand-levers 22, and an arrangement of arms 18, 19, curved links 20, 21, and extension arms 10, 12 of the supporting-members 3, 4. Spring latches 23 hold the levers 22 in their two respective positions, Figs. III and IV. The lifting-frame is also provided with a perforated screen 25 to prevent floating of the skeins on the rods 5, and also with means 15, 16, 15<1>, 16<1> for hoisting the frame. In operation, the lifting-frame is brought to the stand 26, the supporting- members 3, 4 being opened out, and is guided into position over the properly assembled rods 5 and hanks 6 by brackets 30 having tapered walls 31, 32, and, when in position, the levers 22 are swung so as to close the supporting- members 3, 4 over the ends of the rods 5. The yarn can then be raised and lowered into the vat 62. When the dyeing &c. is finished, the operation is reversed, the rods and hanks being redeposited upon the stand, where they may be left to drain and cool while the lifting-frame is loaded from another stand and again taken to the vat. In a modification, Fig. VI, each supporting-member 3, 4 is swung independently, the extension arms being fixed in their respective positions by the co-operation of locking- dogs 40 and notched segmental plates 36. In another modification, Fig. IX, the supporting- members are moved in and out by the operation of a hand-wheel 54 adapted to rotate a shaft 53 provided with worms gearing with worm-wheels 51 on cross-shafts 49. The cross-shafts have right and left handed screwed ends 48, which engage with threaded lugs 47 attached to the members 3, 4. In this modification, the guiding- means for bringing the supporting-frame and stand into proper relation consists of posts 55 and brackets 56.
