Filed July 3,1, 19.614 ,Se,r,.,N0 .-1zs,2,s3 Claims. (Cl. 687-188) This invention` relates to' skein dyeing machines.

In the art of dyeing yarns, the skeins are mounted on sticks which are suspended within a vat and means is provided for cireulating the dyeing liquor' around, and through, the yarn. i n i In order to prevent marking, it is' necessary to minimize contact lbetween the skeins' and the, skein-supporting stick andV it is also necessary thatv the skeins be spaced from each otherv orv arranged in' an operi pattern to permit free flow of the liquor between and through the skeins and thus insure uniform results. l

It is therefore one object of the invention toy produce an improved carrier in which the Skcirsfare supported with minimum contact with their supports; in whichV the skeins are adequately spaced,.wherebyV the liquor circulates between' and' through, the skein'.

Loading" the' skeins onto the supporting sticks and placing the sticksdirectly in theV vat takes. time, during which the vat is idle. K

It is therefore afurther object of the invention to produce` an improved carrier which can be loaded and unloaded outside of the dye vat and which can be dropped into,A and lifted from, the vat quickly and easily so as to reduce interruption of the operation to a minimum.

The full nature of the invention' willV be understood from the following specificationl aud-.accompanying drawings in which:

FIG. l1 is a horizontal, sectional view looking in the direction of line 11-11 on FIG. 10, showing the yarncarrying sticks in one position thereof.

FIG. l2 is a vertical, sectional view looking in the direction of line 12--12 on FIG. 10.

FIG. 13 is similar to FIG. 1l. but showing the yarncarrying sticks in another position thereof.

A dyeing apparatus embodying the invention includes a vat 20 which is adapted to it in an emplacement 22 having a d-rain 24. The vat is supplied with water and chemicals through pipe 26 and is emptied through drain 28.

The vat is divi-ded by partition 30 into two

compartments

32 and 34, the bottoms of which are formed by

feicc screens

33 and 35, respectively. Below

screens

33 and 35 isa heating coil 36 and an impellei" 38 which is driven by pulley 40 which is driven by reversible motor M. When the impeller is rotated in one direction, the dyeing liquor is circulated in the direction of arrows 42, and vice versa. p

The yarn carrier is formed of two sections, A and B, which are adapted to tit

inY vat compartments

32 and 34, respectively. Carrier sections A and B are formed of a common front wall 44, a common rear wall 45 and

inner walls

46 and 47 which are spaced apart to form a channel 48 which is adapted to receive partition 30` when the carriers are lowered in the vat, as shown in FIG. 4. The bottoms of sections A and B are open and their tops are formed of screens 5i) and 52. The opposite ends of carrier sections A and B are open and are provided with overhead sliding' doors 54.

Carrier sections A and B are integral with each other and with a cover 56 which is provided with loop 58 for engagement with' hook 5 9 of a lift', or overhead crane, not shown. By this arrangement, the' yarn carriers and the cover form a rigid assembly which can be lifted from, or lowered into, the vat as a unit. When the lcarrier sections are' lowered into the vat, their bottom edges come to rest onV flexible gasket 59a to form a watertight seal. Also, when the parts are in this position, ang'e 60 `of the cover comes to rest on rim 61 to close' the top of the vat. It will also be noted that the cover is raised above

screens

50 and 52 and` is preferably domed so that, when it is in the` vat closing position of FIG. 4a passa-ge 62 is provided to permit liquor in one of the compartmentasucli' as compartment 32, to ilow upwardly through screens 33` and 50, then horizontally through passage 6.2, then downwardly through screen 52vand 3,5' and' finally upwardly through screen 33 to complete the cycle, as indicated by arrows 42 in FIG. 4'.

In both embodiments, the skeins of yarn are supported on sticks which have only line contact with the skeins'. To this end, the skein-supporting sticks have a crosssection, ysuch as that shown in FIG. 9, from which it will `be seen that upper divergent edges 64 support the skein and that they co-act with lower divergent edges 66 to keep the skein open to permit free circulation of the dyeing liquor around and through the skein, as shown by the arrows in FIG. 9.

Also in both embodiments, the sticks which support the yarn are automatically uniformly spaced to provide clearance between adjacent skeins.

In one embodiment, the skeins are Suspended from the sticks 68, each of which is provided with an enlarged head 70 which may be solid, or which may be in the form of a hollow frame as long as the width of the head, as viewed in FIG. 7; that is, the distance between sides 72 thereof is at least equal to the greatest width of the skeins supported by the sticks so that if the sticks are laid side by side, with the sides 72 of their respective heads touching, the skeins carried by radjacent sticks will be spaced as shown in FIG. 7.

When sticks 68 are used, the front and rear walls, 44 and 45, of the compartments are provided with upper shelves 74 to receive the heads 70 of the sticks from which the skeins are suspended. To load a carrier section, it is merely necessary to pla-ce the sticks, successively, on the outer ends of the shelves and to push them inwardly, or in the direction of arrows 78, until the head of the innermost sticks abuts the

inner wall

46 or 47 of the compartment. See FIGS. l, 6, 7 and 8.

Instead of sticks 68, We may use sticks Si) which have the same cross-section as sticks 68, but which have flattened ends, as shown in FIGS. l0-13. When sticks 80 are used,

shelves

74 and 76 are replaced by

openings

84 and 86 3,063,281l l i ,v I

FIG. 12 that openings 86 are deeper than openings 84 and that the distance between

wall

44 and 45 is greater than the length of sticks 80. In this construction, there is also provided a slide 88 which is movable `relative to wall 45 and has openings 90 which correspond to openings 86. To insert sticks 80, slide 88 is moved until its openings 90 register with openings 86. Sticks 80 are now inserted as far as they will go through openings 86, as shown in solid lines at the top of FIG. 12, and are then moved through openings 84 as far as they will go, as shown at the bottom of FIG. 12. With all of the sticks in their extreme right-hand position, lslide 88 is moved to bring solid portions 92 thereof into registration with openings 86, thus locking stick 80 against lateral movement.

The yarn tends to shrink and to control shrinkage, we provide lower shelves 76 for receiving

sticks

68 or 80 which engage the lower ends of the skeins, as best shown in FIGS. 2 a-nd 3. It will be noted that there are a number of vertically spaced upper and

lower shelves

74 and 76 so as to accommodate skeins of various lengths and so as to provide for a wide range of .shrinkage control. It will be noted that, once the doors are closed, sticks 68, the outermost of which will abut the inside of the doors, will be locked against movement and that when sticks 80 are used, the outer ends of slides 88 will abut the inside of the door and will be locked against any movement.
