DYEING APPARATUS.

Specification of Letters Patent.

Afppliciton filed August ll, 1906. Serial N0. 330,219.

Patented June 4, 1907.

To all whom it may concern:

Be it known that I, LOUIS DEsTRE, a subject of the King of Belgium, residing at Haren, Belgium, have invented new and useful Improvements in Dyeing Apparatus, of which the following is a specification.

My invention relates to improvements in dyeing apparatus and has for its objects the convenient manipulation of banks of yarn connected in a continuous band, during the dyeing thereof, according to the process of dyeing described in the Belgium patent to Destre et al. 1#171,532 of July 14th, 1903, and also in my copending process application of even date herewith.

l n the accompanying drawings which serve to illustrate the preferred embodiments of my invention: Figure 1 is a side elevation of a complete apparatus adapted for ordinary dyeing operations. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical longitudinal section, and Fig. 4 a vertical crosssection of the dyeing tank, isolated. Fig. 5 represents an elevation, partially in section, of a complete apparatus adapted for indigo dyeing.

The apparatus comprises a tank 1, of a suitable type, wherein are arranged two longitudinal apertured or perforated

partitions

2, 2, separated from the walls of the tank 1 by spaces 3, adapted to contain the usual heating pipes and through which the dyebath is introduced into the tank. The space intervening between the two partitions 2, is divided into a plurality of compartments by means of skeleton or apertured

transverse partitions

4, 4, 4 which preferably comprise vertical bars, connected at their lower ends by curved ribs 5, to which are secured planks 6, so that said compartments are closed at the bottom and communicate with each other above said curved bottom portion. Each compartment is divided into two halves 7, S, by means of a partial partition 9, extending from the upper edge of the tank to a point distant above the dealed bottom of the compartment, the distance preferably approximating 'the radius of the said bottom. The lower edge of said partition is rounded or provided with a roller 10 (shown in dotted lines in Fig. 3), in order to facilitate the passage of the hanks through the compartments.

The

partitions

2, 2, 4, 4 are connected together by means of bolts 11, so that these several parts form a unitary device, which can be easily removed from the tank 1 for cleansing or other purposes. Secured in proximity to the upper edge of each partition 2 are opposing blocks 12 preferably of wood and substantially semi-circular in crosssection (suitable rolls may be substituted therefor), which serve to guide the band of hanks, or rather the clips connecting the hanks into a band, and maintain the latter in a proper position on the cylinders 13. The shafts 14 (Fig. 1) of the said cylinders 13, are journaled in bearings 15, arranged on the tank 1v coaxial with the partial partitions 9, and the diameter of said cylinders 13 is proportionate to the width of the compartments, so that the band of hanks is raised and lowered along the axis of each half of

compartment

7, 8, as will be hereinafter described. The shafts 14, of the cylinders 13, carry pulleys or sprocket-wheels 16 over which reeve belts or chains 17, respectively. The said belts also reeve over a pulley or sprocketwheel 18, arranged on the driving-shaft 19, and ournaled in bearings 20, which are support-ed on a suitable frame 21, at the rear of the tank 1. Mounted on the driving-shaft 19, is a squeezing roll or cylinder 22, and above which is arranged a cooperating roll 23, the shaft of which is j ournaled in two levers 24, pivoted as shown at 25. The free ends of the said shaft are pivotally connected as shown at 26 to rods 27, which are guided vertically and carry at their lower ends suitable weights 28, serving to weigh the upper roll 23. When the

mils

22, 23 are to be thrown out of operation, the roll 23 is raised by turning the hand-wheel 29, the shaft 30 of which carries two cams 31 adapted to engage lugs 32 on the rods 27 and raise the latter together with the upper roll 23.

Arranged on the driving shaft 19 are three

pulleys

33, 34, 35, the

pulleys

33 and 35 of which are loose on the shaft, while the pulley 34 is fast on the same. The loose or idle pulleys are connected by means of two belts, a straight belt and a crossed belt, to a pulley of a suitable transmission shaft (not shown). When the one or the other of said belts is brought on the fast pulley 34, the shaft 19 and therefore the squeezing roll 22 together with the rolls 13 of the tank, will be rotated' clockwise or anti-clockwise for the purpose hereinafter described. Theautomatic shifting of said belts is accomplished by means of the following device :@Arranged on the frame 1 are two supporting arms 36, provided with IUO IIO

vertical forks or the like 37, between the branches of which, and longitudinally movable with respect thereto, is a cross-bar 38, the movements of which are facilitated by means of sets of rolls 39 arranged on the guides 37. Laterally of the pulleys 33-35, the said bar carries two belt shifters v40, 41, which are disposed on opposite sides of said pulleys and serve to shift the two transmission belts alternately upon the fast pulley 34 and the

id e pulleys

33 and 35. The crossbar 38 is suitably connected with two balance levers 42 adapted to oscillate on horizontal pins 43 and pivotally connected at their lower ends with a graduated rail 44, on which two lugs 45 may be adjusted, as desired.. Arranged to engage said lugs is a traveler 46, movably mounted on a screwspindle 47 carrying at one end a loose pulley 48 and a fixed pulley 49, adapted to be connected by a belt 50 with loose and fixed pulleys 51, 52, mounted on the driving-shaft 19.

The traveler 46 is provided with a socket 53 by means of which it is guided along a transverse stationary rod 54.

It will be easily understood that when the driving-shaft 19 is rotated in any direction, the traveler 46, which carries with it the rail 44 will be moved on the screw-spindle 47, either to the left or to the right, until it engages one of the lugs 45 whereby the balancelevers 42 will be oscillated. Said balancelevers carry with them the bar 38, and the belt-

Shifters

40, 41 mounted thereon, whereby the belt which has actuated the shaft 19 is shifted on to the idle pulley, while the second belt is shifted on to the pulley 34 with the consequent rotation of the shaft 19 in the opposite direction.

The complete apparatus operates as follows i-First one of the lugs 45 lis removed from the rail 44, to permit of the traveler 46 being shifted from the screw-spindle 47 to the smooth portion of the said rail, whereby the shaft 19 can be rotated constantly in one direction. The same result can be attained by placing the belt 50 upon the two idle pulleys 49, 52. The band of hanks to be dyed is brought in front of the tank 1, a cord or the like is attached to the end of the band and passed through the successive compartments of the tank and over the

rolls

13,13. The apparatus is then started by placing upon the fixed pulley 34 the belt (straight or crossed) which imparts the forward movement thereto, that is, in the direction of the charging of the tank. The rotation of the first roll 12, (on the left hand side of Fig. 1) then causes the band of hanks (indicated in dotted lines, to be moved into the first half 7 of the

first compartment

7, 8, wherein said band is folded upon itself in a continuous and uniform way. As soon as this compartment has received a quantity of hanks corresponding toits capacity (sayO, 60,70 kgs), the

end of the band a is pulled by means of the cord over the second roller 13, the rotation of which causes said band to be folded in the half 7 of the second compartment, while the hanks removed from the first compartment are immediately replaced by the hanks carried away into the tank by the first roller. This operation is continued until all the halves 7 of the successive compartments are filled with the desired quantities of hanks.v Then the machine is stopped, the traveler 46 is again brought upon the screw-spindle 47 by rotating the latter through the medium of a crank-handle or the like (not shown), and the positions'of the two lugs 45 are adjusted according to the length of band accumulated in each half of compartment 7. The machinery being then started again by means of the second belt, the rolls 13 are rotated backwardly or clockwise and cause the hanks, folded upon themselves in the halves 7,'t0 move slowly and regularly into the adjacent halves 8. When the hanks are in the latter half, the traveler 46 engages one of the lugs 45 and thus moves the rail 44 and causes it to oscillate the balance-levers 42 and also to move the belt Shifters, so that the belts are shifted on to the

pulleys

33, 34, 35 with a consequent reversal of rotation, which returns the hanks into the halves of compartments 7. These alternate and continuous movements of the hanks are repeated automatically until the dyeing operation is thoroughly completed. Thereupon, the hanks being folded in the halves 8, the end of the band a is pulled by means of the cord, over the last roll 13 (at the right hand side of Fig. 1) and between the squeezing rolls 22, 23 below which is arranged a suitable pan 55 (shown in dotted lines in Fig. 1). During the movements of the band a, the clips connecting the series of hanks are guided between the wooden guides 12 of the tank to hold the band in proper position on the several rolls 13. After being passed between the squeezingrolls 22, 23 the band of dyed hanks may be brought to a mechanical folding device, or any other apparatus, for the further treatment of the hanks.

The apparatus above described is especially designed for ordinary dyeing operations, that is, those in which the action of air does `not influence the dyeing. In other cases, when the hanks must remain in the bath throughout'the whole operation (i. e. indigo dyeing), I preferably use the apparatus shown in Fig. 5. In this construction the partitions 4 extend upwardly to a level at some distance below the upper edge of the tank 1, the rolls 13 being arranged within said tank, so that they are constantly immersed in the dyeing bath. Moreover the rolls 13 are combined with squeezing rolls 23, provided with any suitable balance-weights or similar devices. This modified tank is IOO IOS

IIO

IIS

also provided with an oxidizing chamber, consisting of a skeleton framing 57, on the lower and upper cross-bars of which are journaled guide rollers 58, the upper rolls being actuated by the driving-shaft 19 through the agency of a belt 59 reeving over a pulley 60. The said pulley is provided with a bevelgear-wheel (not visible) 'preferably integral therewith, which meshes with a bevel gearwheel 61 fast on a transmission shaft 62, and actuates the shafts of said rolls through screws or any equivalent elements thereon, or in any other way.

W'hen the dyeing of the hanks is completed in the tank 1 as described in connection with the ordinary apparatus, the band L is passed between the squeezing rolls 22, 23 and thence slowly over the several guide-rolls 5S of the oxidizing field or chamber. During the latter travel, the dyed hanks are subjected to the action of atmospheric air, which is required for completing the operation in certain cases. After being passed through the oxidizing chamber, the band (L may be brought to a mechanical folding device or any other apparatus as desired.

Instead of causing the hanks to be alternately accumulated in the two parts of each compartment of the tank 1, as herein described, said hanks may be passed in certain cases continuously through the successive compartments of the tank without accumulation therein, which accumulation is necessary only for certain special dyeing operations.

It is evident that the apparatus herein described may be used as a vat, since it permits of the treatment of the bands by way of accumulations within the bath: as a rollertank, since it permits of the dyeing of the band by a continuous passage in a stretched or taut condition on the

rolls

13, 13 as a dipping and washing tank, since it permits of the dipping and squeezing of the band between the several series of rolls: and as a double jigeer, since it permits of the treat-- ment of hanks by alternate immersions. Therefore the apparatus is of a general utilization and may be used for bleaching and dyeing with anilin colors in general or with alizarin, wood-extracts, indigo, etc.

Having thus described my invention, what I claim is:

1. The combination of a dyeing-tank havingpartitions therein forming a plurality of compartments, a guide-roll of a diameter equal to the combined width of a compartment and a partition mounted co-axially on each partition, and means for simultaneously actuating said rolls, substantially as described.

2. In a dyeing-tank, the combination of partitions forming a plurality of communicat- 4. The combination of a dyeing-tank, guiderolls supportedthereby and in gear with each other, a fast pulley and two idle pulleys mounted upon a shaft in gear with said guide-rolls, two oppositely acting transmission belts reeving over two of said pulleys, a pair of balance-levers arranged to oscillate in a vertical plane, belt-shifting-levers connected to the upper ends of said balancelevers, a horizontal graduated rail pivotally connected to the opposite end of said balancelevers, adjustable stop-lugs thereon, a hori- Zontal partially screw-threaded spindle, distinct from said rail, and a traveler sleeved thereon adapted to engage the said lugs and aetuate the said levers, substantially as described.

5. The combination of a dyeing tank, guiderolls supported thereby and in gear with each other, a fast and a-loose pulley mounted upon a common shaft, said shaft being operatively geared with said guide rolls, a transmission belt reeving over one of said pulleys, a belt-shifter therefor, a balanced lever connected with said belt shifter and adapted to actuate the same longitudinally with respect to said shaft, a screw spindle capable of bidirectional feeding, a traveler in gear therewith and arranged to periodically actuate the balanced lever, substantially as described.
