SHEET 3 0F 7 ATTORNEYS I PROCESS AND APPARATUS FOR LIQUID TREATING OF TEXTILE FABRIC The present invention relates to an improved appara tus used in the liquid treatment of textile fabrics, preferably in rope form. More particularly, the present invention relates to an improved liquid treating apparatus for textile material capable of treating the material in a single length or strand, the invention also contemplating a method or process of loading a single length of textile fabric in rope form into a liquid treating tank and then continuously treating the same within the tank.

While the present inventionwill be described in connection with liquid treating apparatus such as a dye beck wherein the fabric is continuously fed into and out of a dye bath of dye liquor, it will be understood that the novel apparatus and method is capable of use in other textile liquid treating apparatus such as scouring machines, washingmachines or the like.

Dye becks which have heretofore been used for dyeing fabric in rope form have utilized a plurality of draw rolls, plaitor rolls and the like positioned above the dye bath and about which separate individual endless strands of fabric in rope form pass continuously into and from the dye liquor. Such apparatus utilizes a peg rack that maintains each of the individual endless strands of textile fabric in rope form separate from one another. The capacity of these dye becks is in the order of fifteen hundred yards of material, there being anywhere from to or more separate endless strands. In the operation of such a dye beck it is necessary to take lengths of fabric, for example, 100 yards of fabric and feed the same into the dye beck about the draw rolls or reels and then sew the two ends of the fabric to gether. For each endless strand, the above procedure is repeated until the beck is filled with the desired number of endless strands of fabric. Thedyeing operation can then be started by loading the heck with the dye liquor and operating the beck until the desired shade is obtained. The unloading of the beck requires the reverse procedure in that each of the individual endless strands must be cut and the fabric removed. If subsequent textile operations require treatment of a continuous'length of fabric, the pieces must then be sewn to each other to make up such a length.

More recently, efforts have been made to utilize a single endless strand in the dye beck in order to obviate the necessity of sewing together the relatively short individual endless strands within the heck, then cutting and resewing into onelong strand or length for subsequent processing. However, such apparatus required much labor in loading the same as a single long length, for example, fifteen hundred yards must be moved through the various feeding devices to properly hand coil into loops and then have the two ends sewn together. Additionally, such dye becks required rather complex mechanisms for moving the long endless strand continuously through the heck into and out of the dye liquor, the mechanisms placing undue strain on the fabric.

A third type of apparatus in the liquid treatment of fabric, involves apparatus capable of feeding a continuous running length or strand into and out of the appara tus having the treating liquid therein. In this type of apparauts difficulties have been encountered in obtaining i a proper and uniform liquid treatment as oftentimes it was difficult to obtain a stability in the treatment of the fabric especially in cases where the fabric is being dyed. For example, if a continuous running length of material is fed from outside of the apparatus into the treating liquid in the apparatus and then out of the apparatus to be rolled therein or to be further processed, such fabric would have different shades due to the exhaustion of the dyestuffs from the dye liquor unless constant vigilance is maintained throughout the cycle of operation. In other words, the maintaining of a quality control for a particular length of goods was nearly impossible as the operator was continually having to check the color of the fabric coming from the apparatus and then adding dyestuffs to the dye liquor so as to compensate for exhaustion; It was difficult to try and match and obtain the same shade throughout the entire length of fabric.

An object of the present invention is to provide an improved and efficient apparatus particularly suited for the liquid processing of fabric in rope form in a single length, the fabric being uniformly treated throughout its entire length.

Another object of the present invention is to provide an improved apparatus capable of liquid treating of textile fabrics in rope form, the apparatus being easily loaded by a single operator attaching one end of the fabric within the apparatus, the remaining length being automatically fed into the apparatus.

Still another object of the present invention is to provide an improved method of automatically loading a liquid treating apparatus with a single long strand or length of fabric and'of treating the fabric strand or length continuously in the apparatus without the necessity of the ends of the strand being sewn together to form an endless strand.

A still further and important object of the present invention is to provide a liquid treatment apparatus capable of liquid treating a long length of fabric, the apparatus having an improved automatic feeding means for feeding the length of fabric from externally thereof into the same and means for continuously immersing the length of fabric in the liquid and removing the length therefrom.

Ancillary to the immediately'preceding object, it is a further object toprovide a feeding and treating mechanisin capable of use with an open apparatus or a pressurized apparatus.

A still further object of the present invention is to provide an improved dyeing apparatus for dyeing a single long length of textile fabric material in rope form, the apparatus providing for smooth, fast uninterrupted movement in the feeding of the textile material to apparatus from externally thereof and then through the dye bath with little or no slippage of the material passing over the draw rolls, the material further being in a completely relaxed or tensionless position when in the dye bath. By having the material in a completely relaxed or tensionless condition, the shrinkage or elongation of the material does not affect the dyeing of the same and, thus, resulting quality defects in the material are eliminated.

Another object of the present invention is to provide an improved dyeing apparatus for dyeing a single long length of textile material in rope form, the apparatus having improved means for advancing the material into and out of the dye liquor with additional means for adjusting the length of the loops of material therein either initially or during treatment so as to provide for miscalculation of length of loops or shrinkage of material.

These and other objects and advantages of the present invention will appear more fully in the following specification, claims and drawings, in which:

FIG. 1 is a horizontal sectional view through a liquid treating apparatus such as a dye beck for textile fabrics made according to the present invention, the view being taken substantially on the line l1 of FIG. 2 and with the structure for the door or closure being omitted;

FIG. 2 is an end elevational view of the apparatus of the present invention looking from the right of FIG. 1, parts of the apparatus being broken away for clarity;

FIG. 3 is a view similar to FIG. 2 but having an upper portion thereof broken away, the broken away portion being taken substantially on the line 3-3 of FIG. 1;

FIG. 4 is a view similar to FIGS. 2 and 3 but showing the upper broken away portion of the apparatus taken substantially on the line 4-4 of FIG. 1;

FIG. 5 is a diagrammatic view of the controls for the present invention;

FIG. 6 is an enlarged fragmentary view of the lower right-hand corner of FIG. 1;

FIG. 7 is an enlarged elevational view of the spiralshaped fabric feed or cloth guide element or peg rack;

FIG. 8 is a generally diagrammatic horizontal sectional view, partly broken away, of a modified form of the apparatus of the present invention;

FIG. 9 is a simplified wiring diagram for the apparatus of FIG. 8;

FIG. 10 is a diagrammatic vertical sectional view of the upper portion of the apparatus of FIG. 8, the view being taken substantially on the line 10-10 of FIG. 8;

FIG. 11 is a view similar to FIG. 10, but being in elevation and illustrating the various drive elements for the apparatus; and

FIG. 12 is a diagrammatic plan view of a modified form of movable peg rack or cloth guide usable with either the apparatus of FIG. l or FIG. 8.

Referring now to the drawings wherein like character and reference numerals represent like or similar parts, the method of the present invention is brought out best by first giving a description of the improved liquid treating apparatus for the textile material.

The apparatus will be described in its preferred form as a dye beck but, as mentioned above, both the apparatus and the method involved are capable of use in any textile treating process involving the use of liquids such as scouring or washing machines or the like. The dye beck of the present invention is generally designated by the numeral 10 and is preferably a cylindrical tank disposed on a horizontal axis and having

end walls

12 and 14. All of the interior parts of the dye beck H0 or the parts of the system which come into contact with corrosive water, chemicals or dyestuffs are desirably constructed of stainless steel or other corrosive resistant metals or corrosive resistant plastics. It will be understood that the tank of the dye beck 10 is of liquid tight construction and is provided with an opening 16 in its side wall 17 through which the textile material to be treated is inserted and removed and through which the interior of the beck may be serviced by the operator or maintenance personnel. The opening 116 may be provided with a closure 18, the closure 118 having the usual seals thereon if the dye beck is to be used as a pressure beck rather than an open beck.

The end walls 12 and 13 for the dye beck 10 are provided with the usual vertical stiffening members 20 on both the upper and lower

semi-cylindrical sections

22 and 24 respectively. The

sections

22 and 24 are bolted together through the flanges 26, there being a gasket 28 placed therebetween for providing a seal and air-tight relationship if the dye beck is to be pressurized.

The interior of the dye beck in the lower portion thereof where the dye bath is heated may be similar to that disclosed in the copending United States application of Robert A. Gilliam and John V. Isley Ser. No. 301,437 and filed Aug. 12, 1963. Additionally, the dye bath may be heated by suitable closed steam coils (not shown) provided between a false bottom and the side wall 17 of the beck, the controls for the steam coils and the steam coils themselves being of the type shown in either of the US. patents of John V. Isley and Robert A. Gilliam numbered 3,094,858 and 3,094,859 and both issued June 25, 1963.

A bracket 30 mounted exteriorly of the end wall 12 supports an electric motor 32 or other suitable source of power. The electric motor 32 provides the prime source of power for a driven'draw roll 34 which extends horizontally within the tank or beck 10 between the end walls 12 and 13. In more detail, the driven roll 34 is mounted on a shaft 36 extending through a liquid tight bearing 38 on the end wall 12, the other end of the shaft being supported on a similarly mounted bearing 40 carried on the opposite end wall 14. A driven sprocket 42 (FIG. 2.) mounted on the exterior portion of shaft 36 extending from the wall 12 receives an endless drive chain 44 which extends about a drive sprocket 46 on the drive shaft 36 of the motor 32.

A second roll 48, which is also horizontally disposed within the dye beck I0 is mounted on a shaft 50 suitably supported in the

end walls

12 and 14 by bearings 52. The roll 48 has its axis of rotation parallel to but slightly below the axis of rotation of the driven roll 34. While the roll 48 is shown as an idler roll, it will be appreciated by those skilled in the art that the roll 48 may be positively driven at the same surface speed as the roll 34 off of the'roll 34 by suitable chain drive or the like. As best shown in FIGS. II and 4, both the

rolls

34 and 48 are positioned adjacent the rear of the'dye beck 10 above the level of liquid of the dye bath in the lower portion of the dye beck, the roll 34 being positioned slightly above the roll 48 and closer to the rear of the dye beck.

An idler roll 54 is mounted adjacent the front of the dye beck 10. The idler roll 54 which has an axis of rotation parallel to the axes of rotation of the driven roll 34 and roll 48 also extends horizontally between the

side walls

112 and 14, the roll being mounted on a shaft 56 which has its ends suitably supported in the bearings 58 and 59. The bearings 58 and 59 which are positioned on the exterior of the

end walls

12 and 14, respectively, are liquid tight bearings similar to the

bearings

38 and 52. Roll 54 is preferably mounted at an elevation in the tank intermediate the elevation of the

rolls

34 and 48 and as will now be understood, this roll is also positioned above the level of the dye bath within the dye beck 10. Further, roll 54 may be positively driven at the same surface speed as

rolls

34 and 48, if so desired. While the guide rolls 34, 48, and 54 have been illustrated as mounted on shafts extending therethrough and supported adjacent their ends, it is, of course, understood that the shafts for the respective rolls may be stub shafts supported in the

respective end walls

12 and 14 of the dye beck 10, the rolls being rotatably mounted on the stub shafts except for the driven roll or rolls which would have to be splined or keyed to the driven stub shaft or shafts.

As best shown in FIGS. 1, 4, 6, and 7, a spiral-shaped element or rotatable peg rack 60 is provided in the front portion of the dye beck immediately below the idler roll 54 and slightly forward of the same. The spiral-shaped element 60 serves two functions in the operation of the dye beck. First, the spiral-shaped element 60 functions as a means to assist in the automatic feeding of textile fabric into the dye beck and the forming of successive loops therefrom prior to the liquid treatment of the fabric and the automatic removal of the fabric from the dye beck at the end of the liquid treat ment of-the same. Secondly, the spiral-shaped element The spiral-shaped element 60 which is preferably made from stainless steel comprises an elongated shaft 62 which has one end supported in a bearing 64 on the interior surface of the end wall 14 and the other end extending through the end wall 12 and supported on a liquid tight bearing 66. Mounted on the shaft 62 concentrically thereof is a spiral or helical shaped wire member 68which defines a helix throughout the length of the same providing a plurality of movable spaces or pockets 70 for reception of the fabric in rope form. The wire member68 is supported on the shaft by a plurality of radially extending braces or spokes 72.

, Referring now to FIGS. 2 and 6, a driven sprocket 74 is mounted on the end of the shaft 62 which extends exteriorly of the end wall 12. A bracket 76 suitably carried on the end wall 12 supports a gear head electric motor 78 having a drive sprocket 80 on its drive shaft. An endless chain 82 extending about the drive sprocket 80 and the driven sprocket 74 rotates the driven sprocket 74 one revolution each time the motor is energized as will be explained later in the specification.

Referring now to FIGS. 1 and 2, a guide or threading eye 84 supported by a bracket 86 carried by the dye beck 10 or by frame structure adjacent the dye beck 10 is positioned adjacent the opening 16 at an elevation threading eye 84 is arranged to receive the textile fab- .ric F in rope form from a cart or vehicle V and feed the same over the roll 54, under the roll 48 and over the I driven roll 34. It will be understood that the fabric F on the cart V is the total yardage of fabric to be treated.

. these long lengths of fabric and thus there is material reduction in the amount of labor involved in preparing for the liquid treating process. A more detailed description of the loadingoperation of the fabric F and reason for having the pivotal guide eye 84 adjacent the beck opening will follow later in the specification.

Referring now to FIGS. 1, 3, and 6, a stainless steel endless chain 88 is suitably mounted for movement in a confined endless path adjacent the interior of the end wall 12. The endless chain 88 passes about a driven sprocket 90 and a pluality of plurality sprockets 92 and is arranged to follow substantially the same path as a loop of the fabric F follows when above the liquid level of the dye bath and passing over, under and over the

rolls

54, 48, and 34, respectively in the direction of the arrow B in FIG. 4. Each of the idler sprockets 92 are suitably journaled for rotation on stub shafts 94 supported on the interior ofthe end wall 12 whereas the driven sprocket 90 is keyed to a driven shaft 96 extendingthrough the end wall 12 and rotatably supported in a liquid tight bearing. The shaft 96 has splined thereon for movement longitudinally thereof a gear 98 movable by an air clutch 100. When the gear 98 is in the position shown in FIG. 1, it is in engagement with a gear 102 keyed to the driven shaft 36 of the driven roll 34 and thus will be rotated thereby so as to rotate the shaft 96 I and move the chain 88 over the idler sprockets 92. The air clutch is suitably carried by a bracket 104 mounted on the end wall 12 of the dye beck 10.

Referring to FIG. 6, the chain 88 has extending from one of the links thereof a rigid member 106' which carries a flexible leader 108 (FIG. 1 and FIG. 6). The leading end of the textile fabric F is suitably attached to the flexible leader 108 by sewing or tying the same thereto and, thus, the leading end of the fabric F substantially follows the path of the chain 88 when the chain is moving about its sprocket in its confined endless path. It will be noted that the confined endless path of movement of the leading end of the fabric F is in a plane extending transverse of the axes of the

rolls

54, 48, and 34 and the length of the leader 108 is sufficiently long to insure the leading end of the fabric F being immersed inthe treating liquid during the travel'of the leader along the lower portion of the apth of the chain.

Referring now to FIG. 5, it will be noted that a pulse timer 114 is provided for controlling the rotation of the spiral-shaped element 60 and actuation of an air valve for the air clutch 100 in a particular timed seabove thespiral-shaped element 60. The guide or quence. Inmore detail, a flexible cable 116 extending off of and driven by the continuously rotating shaft 36 of the driven roll 34 causes the timer'l 14, upon a predetermined number of revolutions of the shaft 36, to send a pulse to and energize a time delay. relay 112 so that the motor 78 can be energized a sufficient period of time to permit the same to rotate the spiral-shaped element 60 one complete revolution. At the end of one complete revolution of the spiral-shaped element 60, a lug 1 18 on the sprocket 74 of shaft 62 actuates a switch means 120 to close a circuit to a time delay relay 122 whereby the same may be energized by a pulsealso from the timer 114 for a predetermined length of time. The time delay relay 122 operates the air valve 110 to its open position which in turn causes the air clutch to move its driven member 98 into engagement with the drive member or gear 102. The time delay relay 122 actuates the air valve 110 for a sufficient length of time to permit the rethreading chain 8l8to make one complete revolution and thus thread the fabric or cloth through the empty pocket in the end of the spiralshaped element 60. The pulse timer 114 is so synchronized with the rotation of the loops of fabric through the dye beck 10 that it causes the spiral-shaped element 60 and the rethreading chain 88 to each make one complete revolution in the above-described timed sequence for each complete revolution of the loops of fabric through the dye beck 10. Further, it will be noted that the gear 98 and the gear 102 are of a lzl ratio, and thus, the movement of the rethreading chain 88 is at the same velocity as the surface velocity of the positively driven roll 34 and the fabric traveling therewith.

The operation of the dye beck 10 may be described as follows: The dye bath with the proper amount of dyestuff is prepared in the dye beck 10 prior to the insertion of the fabric F in rope form therein as once the operator has attached the leading end of the fabric F in rope form to the flexible leader 108 and has started the continuously operating electric motor 32, the fabric will be automatically fed into and threaded about the

rolls

54, 48, and 34 to form successive continuous spiral loops with the liquid treatment of the loops following as soon as all of the fabric has been fed from the cart or vehicle V without any other operations on the part of the operator.

The operator threads the leading end of the fabric through the pot eye 84 over the roll 54, under the roll 48 and over the roll 34 and then directly to the leader 108 at the opposite end of the dye beck, as shown in FIG. 1 in broken lines. Then the operator attaches the leading end of the. fabric to the leader 188 by sewing, tying or clipping. Once this has been completed, the operator then divides the total yardage of the single strand or length of fabric F on the cart by the number of loops that the dye beck 10 is capable of handling and thus determines the yardage for each loop. The length of the spiral-shaped peg rack 60 and the number of pockets along its length or the pitch of its helix determines the maximum number of loops the dye beck 10 will take. With the knowledge of the yardage for each loop of a particular length of fabric F, the pulse timer is adjusted by the operator to deliver one pulse for each rotation of a loop through the beck. Once the leading end of the fabric F is attached to the leader 108 carried on the chain 88, the electric motor 32 is started and continuously drives the driven roll 34 throughout the automatic feeding and treating of the fabric. This will cause the fabric F to begin feeding over roll 54,,under roll 48 and over roll 34 into the bottom of the beck as the leading end of the fabric F is not moving during this initial feeding into the dye beck 10 as it is attached to the leader 108 and the chain 88 at this time is stationary.

However, after a predetermined amount of fabric F has been fed into the bottom of the beck, the pulse timer 114 operatively receives a signal through the flexible cable .116, the pulse timer in turn starting the sequence of operation for first rotating the spiral-shaped element 60 one revolution and then rotating the rethreading chain 88 one revolution during a dwell of the spiral-shaped element 60. In more detail, the pulse timer 114 supplies a signal to the time delay relay 112 to actuate the same for a predetermined amount of time, this in turn energizing the motor 78 which will rotate the spiral-shaped element one complete revolution. During this initial revolution of the spiral-shaped element 60, there will be no effect on the fabric F as it has not as yet been threaded up through the first pocket 70 of the spiral-shaped element 60.

After one complete revolution of the spiral-shaped element 60, the lug 118 on the sprocket 74 of shaft 62 will have rotated to a position where it closes the switch means 120 to the time delay relay 122. This permits the timer 114 to send a signal and energize the relay 122 for a predetermined length of time so that the air valve 110 is open long enough to cause the air clutch 100 to engage the gear 102 with the gear 98 whereby rotation of the gear 98 rotates the chain 88 a complete revolution in the direction of the arrow A. When the chain rotates a complete revolution, it will carry with it the fixed leading end of the fabric F up through the first pocket 70 in the spiral-shaped element and will further carry the end over the roll 54 under the roll 48 and over the roll 34 back to the position shown in FIGS. 1 and 6 just beneath the spiral-shaped peg rack 60. Since the chain is carrying the end of the fabric F at the same speed as the fabric is being moved by the draw roll 34, a complete loop is formed as shown in FIG. 4 with a pleated portion being retained in the bottom of the dye beck 10, the pleated portion being formed during the initial movement of the fabric into the beck when the chain is stationary. By having the fabric pleated when in the dye bath, the fabric is in an entirely relaxed and tensionless condition during its direct contact with the dyestuff.

After the first loop of fabric is formed, the second loop begins to be formed as the fabric is being continuously fed into the dye beck 10 by the continuously driven roll 34. When sufficient additional fabric has been fed into the bottom of the dye beck 10, the se quence of operation of the spiral-shaped element 60 and the rethreading chain 88 is repeated. In other words, the spiral-shaped element 60 makes a complete revolution and the fabric F of the first formed loop which is in the first pocket or space 70 of the spiralshaped element 60 will move to the left of FIG. 6 or 7 leaving the first pocket empty for reception of the fabric F during the next cycle of movement of the rethreading chain 88. While the above operation is going on it must be remembered that the draw roll 34 is continuously rotating and the second loop is beginning to form by pleating in the bottom of the dye beck. It will now be apparent that the loops of fabric are successively formed from right to left of FIG. 1 and are rethreaded in step-by-step increments toward the left of FIG. 1 upon formation of each loop by the cycle of operation of first moving the spiral-shaped element 60 through one complete revolution and then the chain 88 through one complete revolution until all of the fabric has been removed from the cart V or other source of supply and is in the beck.

Once the dye beck 10 is completely filled with the single length of fabric F in rope form, the trailing end of the length of fabric F merely follows around loosely in an unconfined path whereas the sequential operation referred to above is continuously repeated with the formed loops continuously moving in a path(arrow B FIG. 4) into and out of the dye bath. This operation continues for as long as desired to obtain the liquid treatment of the fabric required.

After the liquid treatment of the fabric has been accomplished and it is desired to unload the dye beck l0,

the motor 32 is stopped so that the leading end of the fabric F can be loosened from the rigid member 106 and directed back through the pot eye 84 into the truck or vehicle V. The motor 32 is again started so that the sequential operation described above continues as the fabric is fed through the eye 84 into the cart V. The loops of fabric will be taken out of the beck from the right to the left of FR]. 1.

It will now be obvious to those skilled in the art that the improved dye beck and process heretofore described accomplishes the objects and advantages of the present invention. The labor involved in loading the dye beck and in operating the dye beck is materially re duced as the fabric to be treated is in a single uninterrupted lengthand does not havev to be sewn into short endless loops, each loop being individually made up in the beck by the operator. Further, the dye beck results in more uniform dyeing of the total yardage of fabric as the fabric can be brought into the beck, the dye bath then being inserted and the temperature quickly raised. lnother words, the present process and apparatus eliminates streaking and provides for uniformity of dyeing throughout the entire length.

Referring now to FIGS. 8-11 inclusive, there is disclosed another preferred modification of dye beck 10 which is also a cylindrical tank disposed on a horizontal axis and having

end walls

12 and 14. As in the dye beck 10, the interior parts of the dye beck 10 which come in contact with corrosive water, chemicals or dyestuffs are desirably constructed of stainless steel or other corrosive resistant metals or corrosive resistant plastics. The dye beck 10 is provided with an elongatedopening 16' in its side wall 17, the opening 16 being provided with the usual pressure tight closure (not shown).

in the dye beck 10' there is provided a large driven or draw roll 150 which extends on a horizontal axis. A shaft 152, supporting the roll 150 extends through suitable liquid tight bearings 154 carried on the side walls 12' and 14, respectively. The roll 150 is positioned adjacent the opening 16' of the tank and is continuously driven by an electric motor 156 through a chain and sprocket arrangement 158. v

A second roll 160 is supported within the tank of dye beck 10 adjacent the rear wall 19, the roll 160 being mounted on a shaft 162 extending through suitable bearings 164 carried on the

end walls

12 and 14, respectively; The roll 160 is disclosed as an idler roll but it will be appreciated that this roll may also be driven just as the roll 150, it being understood that when the roll 160 is driven, it must be driven at the same surface speed as the roll 150. Since the roll 150 is the driven or draw roll and must drive all of the successive depending loops of fabric as they are rotated into and out of the treating liquid in the tank, the diameter of this roll is quite large as compared to the diameter of the idler roll 160.

A spiral-shaped element or rotatable peg rack 60', substantially similar in construction to the spiralshaped element 60 heretofore described, is provided within the dye beck l0'- and is adapted to continuously rotateon an axis parallel to the axes of the

rolls

150 and 160. The axis of the spiral-shaped peg rack 60 is spaced forward of and below the axis of the roll 150 as best shown in FIG. 10. The spiral-shaped element 60' rotates on a shaft 62' extending through bearings 166,

the shaft 62' having an end portion 64' which extends a substantial distance exteriorly of the side wall 12.

A speed reducer unit 168 which may be of the type such as a Link Belt Company lP.l.V. Speed Reducer Unit, has an input shaft 170 for positively driving at variable speeds an output shaft 172. The input shaft 170 drives the output shaft through a positive chain drive (not shown) which may be adjusted by an adjustment wheel 174 whereby the speed of the shaft 172 may be selectively varied relative the speed of the input shaft 170. lnput shaft 170 is driven off of the shaft 152 of roll 150 by means of an endless chain 178 passing about a sprocket 180 on the shaft 152 and a sprocket 182 on the shaft 170. Shaft 62 is operatively connected to the speed reducer unit 1.68 for continuous rotation by means of an endless chain 184 passing about a sprocket 186 on the shaft 62' and a sprocket 188 on the shaft 172. The speed at which the spiral-shaped ele ment 60 continuously rotates is such that a pocket of the element moves one space during the time it takes the roll 150 to rotate the loops of textile fabric through one complete revolution in the tank. By utilizing the adjusting wheel 17 1 of the speed reducer unit 168, the speed of rotation of the spiral-shaped element 60 can be initially adjusted for the desired lengths of loop to be formed within the dye beck 10 or it may be adjusted during operation of the dye beck to accommodate for a miscalculation in the original length of the loops or for shrinkage of the material which would necessarily decrease the length of the loops.

Adjacent the rear wall 19' of dye beck 10 is an oscillating plaitor member 190 mounted on a shaft 192 extending through bearings 194 carried on the side walls 12 and 14'. The plaitor member 190 is oscillated by a cam 196 carried on the shaft 162 of roll 160. A lobe 198 on the cam engages an arm 200 on and extending than the chain 88 since the dye beck 10 of FIGS. 8-11 has only two rolls over which the cloth passes and consequently the endless path of the chain 88 is arranged to follow substantially the same path as the path of a portion of a loop of fabric Ffollows when the same is above the liquid level of the dye bath. Arigid member 106' is provided on the chain 88 for attachment of the flexible leader of the leadingend of textile fabric when the length of the same is being fed into the beck. For each revolution of a loop of textile material through the dye beck 10', the rethreading chain 88 rotates one. complete revolution in its endless path at the same speed as the fabric is driven by the roll 150. Since the chain is of considerable shorter length than the length of a loop of textile material, it will be obvious thatthe chain will be moving for only a short period of time during each revolution of the loops.

Chain 88 extends about sprockets 202 and 204 which are mounted on the shafts 62' and 162 respectively, the sprockets 202 and 204 being freely rotatable relative to the shafts. Additionally; the chain 88' passes around a drive sprocket 206 carried on a stub shaft 208 extending through the side wall 12 of the dye beck 10. The shaft 208 carries a driven member 210 of an air clutch 212 which is normally disengaged from a drive member214 in the form of a sprocket freely rotatable on the shaft 208. The drive member or sprocket 214 is continuously driven off of the shaft 152 by means of a chain 216 passing around a sprocket 218 keyed to the shaft 152. As is now apparent, when the clutch 212 is actuated the driven member 210 engages the drive member 214 and this causes the shaft 208 to rotate thus causing movement of the endless chain 88.

Referring now to FIG. 9, a simplified wiring diagram for operating the rethreading chain 88 is disclosed. An air valve 222 for supplying air from a suitable source of supply to the airclutch 212 is actuated by a solenoid or relay 224. The relay 224 is in an electrical circuit having a master disconnect switch 226 which is closed when the dye beck 10 is started. As will be apparent from FIG. 9, the relay 224 is energized when'a normally open switch 228 is momentarily closed. The switch 228, as shown in FIG. Ill, is actuated by a lug 230 provided on a gear 232 carried on a stub shaft 234, the gear 232 meshing with a continuously rotating gear 234 carried on the extended portion 64' of shaft 62. Upon energizing the relay 224, the clutch 212 is immediately actuated so that the shaft 208 starts to rotate carrying with it the chain 88. Shaft 208 is provided with a gear 236 (FIG. 11) which meshes with a gear 238 carried on a stub shaft 240. The gear 238 is provided with a lug 242 that engages and opens a switch 244 which is in a holding circuit for the relay 224. As soon as the gear 238 starts to rotate the switch 244 closes the holding circuit andmaintains the relay 224 energized for a sufficient length of time to cause the chain to make one complete revolution. In other words, one revolution of the gear 238 corresponds to one revolution of the chian 88' through its endless path and thus when the lug 242 comes back to the position shown in FIG. 11, it will open the switch 244 which immediately disengages the air clutch 212 to stop movement of the chain 88'.

As a safety measure, should the chain 88 be hung up for any reason before it has completed its movement, a timer 250 is provided for actuating a relay 252 which in turn opens a switch 254 in the circuit for the main motor 156 of the dye beck 10. The timer is arranged to actuate the relay 252 30 seconds after the chain 88 stops for any reason prior to its complete revolution and thus the main motor 156 is stopped so that there can be no damage to the dye beck 10' or to the fabric being treated therein.

As shown in FIGS. 10 and II, a pot eye or threading eye 256 is provided exteriorly of the dye beck and is fixedly attached relative to the dye beck 10 by a support 258. The pot eye is in front of the opening 16 of the dye beck l and arranged about half way between the end walls 12' and 14 of the same. The pot eye 256 is arranged to swivel on a vertical axis to accommodate the feeding of textile fabric to and from the dye beck The dye beck 10' is operated in a substantially similar manner to the dye beck 10 although there are some slight changes with respect to loading and unloading the same. In either instance, the loading and unloading is completely automatic once the end of the fabric F has been attached to the rigid member 106 of chain 88'.

In FIG. 10 it will be noted that the fabric F which is threaded through the pot eye 256 is passed under the spiral-shaped element and placed in the first pocket of the same adjacent the chain 88. Then the fabric is fed upwardly over the draw roll I50 and downwardly over the idler roll 160 with the end of the fabric being attached to the rigid member 106 of the chain when a sufficient length of fabric has been placed in the beck to form one loop. The dye beck I0 is then started and the loading is then the same as the loading described with respect to the dye beck 10 with theonly difference being that the spiral-shaped element 60' is continuously rotating rather than having an intermittent rotation as heretofore described. The swivel mounted pot eye 256 follows the fabric as the loops are being successively formed, the loops filling the pockets of the spiralshaped element 60. I

The unloading of the dye beck 110 is the reverse of the above described method. The end of the fabric attached to the rigid member 106 of the chain 88' is released and threaded back through the eye 256 and as the fabric loops continue to rotate in the dye beck, the loops are successively fed out of the dye beck from the end 12 near the chain 88 toward the opposite end 14 of the dye beck 10'.

Referring to FIG. 12, there is disclosed a movable peg rack 260 which may be used in place of the spiralshaped elements 64) or 60 of

dye beck

10 and 10 respectively. The movable peg rack 260 includes an endless belt or chain 262 passing about

sprockets

264 and 268 respectively. The belt or chain 262 has a plurality of outwardly extending fingers 270 which define pockets 272 therebetween for loops of textile fabric F. In the arrangement shown in FIG. 12, the movable peg rack 260 with its fingers 270 is arranged to move in a horizontal plane so that the pockets 272 also move in a direction away from the rethreading chain. Of course, the

timing of the movment of the pockets 272 must be identical with the movement of the pockets of either of the spiral-shaped

elements

60 or 60 so that there is always an empty pocket in which the leading end of the length .of fabric is fed. It will now be apparent that to obtain the above movement of the rack 260, the

shafts

274 and 276 upon which the

sprockets

264 and 268, respectively, are mounted, must have their axes vertical.
