APPARATUS FOR DYEING SKEINS.

Application filed January 4-, 1910.

To all whom it may concern:

Be it known that we, JUAN Rnoonnosn and LUIS Bneonnosn, manufacturers, subjects of the King of Spain, residing at Barcelona, in the Province of Barcelona and Kingdom of Spain, have invented certain new and useful Improvements in Apparatus for Dyeing Skeins; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in apparatus for dyeing skeins, in which the skeins are arranged in continuous rows and are passed through the baths steadily.

The object of the present invention is to separate the threads of each skein as it enters the bath, thus forcing the liquid to circulate between the threads, which results in a more uniform and satisfactory dyeing of the same.

Other objects will appear in the detailed description.

In the accompanying drawings-Figure 1 is a section of a portion of an apparatus adapted to carry out our invention, taken on the line 11 of Fig. 2. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section, looking downwardly, taken on the line 33 of Fig. 1, with the chains and the skeins removed. Fig. l is a horizontal view, showing the mechanism for producing alternate oscillations of the chains. Fig. 5 is an end view thereof. Fig. 6 is a plan view of a modified form for producing the same movement. Fig. 7 is an end view of the parts shown in Fig. 6. Figs. 8, 9, and 10 are vertical sectional views of a part of a machine, with various forms of mechanism for agitating the liquid.

The dyeing operation is carried on in vats such as f, Along the sides of these vats are parallel rails r, on which is mounted the skein carrying part of the apparatus, being supported on rollers 79, whereby the whole apparatus may be easily moved from one vat to another to take advantage of the difi'erent baths, when desired. On these rollers p is mounted a frame, preferably triangular in Specification of Letters Patent.

form, which supports the shafts and other means for 110] d1ng the traveling chains.

0 represents the traveling chains, of which 7 there are two, arranged parallel with each other and furnished at intervals with spring clips 6. In these clips cross pieces 6 are adapted to be slipped, carrying the skeins a, and the cross pieces 6 are united by elastic connections 6 in order to keep them in place. The clips 6 on the chains are arranged parallel to each other, so that practically the whole space between the chains may be filled with skeins, as indicated on the lower part of Fig. 2. These chains run at the bottom over supporting rollers cl, (Z and (Z mounted in a triangular frame. This frame includes horizontal cross pieces h and vertical guiding rods 71. which engage with grooved rollers t carried by the main supporting frame, so that the entire frame supporting the rollers (Z, (P, and (Z may rise freely, being guided by the four rollers 25, and tends to return to its normal position, as shown in Fig. 1, by its own weight. At the top, the chains 0 run over rollers 0 supported in suitable bearings in the main frame 28, and between these rollers, though .on a lower plane, is arranged a shaft 14 provided with weights M The shaft 20 is loosely supported in slots in the uprights '2), carried by the main triangular supporting frame 28. Any suitable means may be employed for causing the chains to travel continuously into and out of the bath in the vat On the shaft 10 rollers 11, are mounted, under which the chains 0 pass. The combined weight of the parts if, the shaft 24 and rollers u is suilicient to counterbalance the weight of the chains 0 and parts carried thereby. As the chains 0 emerge from the bath, the skeins pass between squeezing rollers z and between brushes j, which have both a rotary and a reciprocatory movement. The rollers z and brushes 7' are for the purpose of preventing dripping.

As the skeins enter the bath, they are agitated in the following manner: a represents a roller bearing against the slrcius and mounted on a suitable shaft 29, which shaft has enlargements 2 engaging the chains 0.

The roller .2 is agitated in the following manner Its supporting shaft is supported by arms 9 loosely mounted on a fixed horizontal shaft g, and the parts 9 are also connected to curved arms 9. 70 represents a disk driven by any suitable motor (not shown) and having on it a crank pin 30 to which is fixed an arm 70 which bears on its end a roller 31 engaging a slot 82 in the benta-rm g. By this connection, itis obvious that the rotation of the disk 70 will swing the roller 2 and the chains 0 in a substantially horizontal direction. To make the movement more effectual, another roller :2: on the inside of the chains 0 is preferably employed, which is supported on arms x pivotally mounted on a part of the main supporting frame 28. Links m connect the supporting arms g with the supporting arms m so that the rollers .2 and :0 will be vibrated in unison.

Pivot-ally connected to the crank pin 30 on the disk 70 is an arm Z, the upper end of which is connected to a bent arm m, which arm is in turn connected to the shaft n of the rocker a which is pivoted between the ends of the shafts 83 and 34 carrying the brushes j, so that by the construction just described the brushes will have a reciprocatory movement in opposite directions. These brushes are mounted to run loosely so that they revolve by the motion of the chains. They comb out the threads, part them from each other, and leave them quite seaarated and almost dry.

In order to increase the eiiiciency of the movements of the skeins in the liquid, the roller (Z is reciprccated longitudinally by the following means: On one of the rods h is secured a bracket 35, in which is pivotally mounted a lever 0, which is located between the shaft 36 of the roller (Z and the shaft 33 of one of the brushes j. It is provided with forked ends, which engage in recessed collars on these shafts.

The operation is as follows: The skeins a being stretched upon the chains 0, these are united by the elastic bands 5 and slipped into the spring clips 6. The chains 0 are then set in motion, by any suitable means, and the skeins are carried first downwardly into the bath, then across over the rollers (Z, (Z (Z and then up between the squeezing rollers 2' and the brushes this operation being repeated as often as desired. As they pass downwardly into the vat the chains carrying the skeins are reciprocated back and forth, thus agitating them and insuring a thorough dyeing of the threads thereof; Then as they pass over the rollers (Z, (Z and (Z they are bent and therefore subjected to tension, which tends to spread the threads and insures that any undyed portion shall be saturated. After passing through the squeezing rollers 2' to remove the excess of dye, the skeins are combed and the threads thoroughly separated by the rollers j, and this operation being repeated as often as desired insures that every thread,'and each part of every thread, shall be thoroughly impregnated with the dye.

Any means for producing relative motion between the dye liquor and the skeins as they are passed through it may be used, as shown in the modified forms, Figs. 4 to 10. F or example, the rollers .2 could be reciprocated in the direction of its axis, if desired. Furthermore, alternate movements in op posite directions of the parallel chains could be produced so as to produce a semicircular movement of the skeins. In Figs. 1 and 5, an arrangement for producing this movement is illustrated, and in this modification a bar 4: is placed behind or inside the skeins, carrying a roller 9, opposite one chain, and a bar 7, parallel to the bar l, is placed in front or on the outside of the chains, carry ing a roller 8, opposite the other chain. The bar 1 is hung from the shaft 1 by means of links 3, and the bar 7 is hung from the shaft by links 6, the links being connected by rods 2, one end above and one below the point of suspension, as shown in Fig. 5. The result of this construction is that as these parts are swung back and forth, as already described in connection with the rollers x and 2, the roller 8 pushes one chain out of line, while the roller 9 pushes the other chain in the opposite direction, producing a semicircular movement of the chains. In Figs. 6 and 7 is illustrated another form for producing this agitating movement. In this modification, an oscillating arm 10 rocks an arm 12, which by means of a connection 17, carries on one end the trunnions or bearings of the rollers 15 and 16. A second shaft 11, oscillating in the opposite direction, has an arm 13 connected thereto, which arm carries a shaft 14, in which are located the other bearings of the ends of the rollers 15 and 16.

Instead of agitating the chains carrying the skeins, the liquid in the bath may be agitated, or both the liquid and the chains may be agitated, if desired. In Fig. 8 is shown one means of agitating the liquid, in which the rollers ac and .2, shown in Fig. 1. are replaced by horizontal paddles 1S and 19, the oscillatory movement of which forces the dyeing liquid through the skeins carried by the chains 0. The paddles 18 and 19 are mounted on arms 20 and 21, pivotally mounted on shafts 22 and 2-3 and connected together by links 2st, the whole being operated by the curved arm g, moved by the arm or rod 7e, pivotally connected thereto and to a crank pin 80 on the revolving disk 70. In Fig. 9, still another means of agitating the liquid is shown, consisting of shafts 25,

provided with paddles 26, which are revolved by cords or belts 27, driven by the disk in.

In the modification shown in Fig. 10, the paddles are dispensed with and the liquid agitated in the following way: 28 represents pipes located on opposite sides of the chains 0 and each provided with a series of small openings directed toward said chains. A pump (not shown') sucks in the liquid and forces it through the pipes 28 in the form of a series of jets thrown against the skeins a carried by the chains. After the dyeing operation in one vat, f, has been finished, the frame carrying the rollers (Z, (Z, and (Z is raised above the top of the vat, sliding on the pulleys t, and the whole ap paratus may then be moved over another vat f containing, if desired, a different dyeing liquid. The frame is then allowed to fall to the position indicated in Fig. 1 and the dyeing operation continued in the vat f, as already described.
