Application October if This invention relates to an apparatus for supplying threads, or yarns of any material and ci various colors to textile machines such as e. g. sewing machines, weaving machines, knitting machines and the like.

According to my invention white threads i. e. undyed` threads which may be bleached or uri-a bleached and which are supplied trom a reel or the like are dyed and dried before the same are supplied to the textile machine. The threads, yarns or the like may be dyed in any desired color or the threads may, ii desired, be used without dyeing.

In the manufacture oi garments such as mens. ladies and childrens wear and underwear, shirts, shorts and the like as well as in the manufacture of shoes, textile fabrics, hosiery fabrics which are made by weaving and knitting threads, including silk threads, yarns, and the like must be used which have a dierent color. If e. g. colored shirts are sewn the sewing must be interrupted several times in order to thread another 'thread of a diierent color. This operation consumes time and a certain care must be exercised which is detrimental to mass production.

lin accordance with my invention the thread, yarn or the like is dyed on the textile machine. it a thread of another color is required, instead of threading another colored thread, by the simple operation of a knob or the like the thread may be dyed in the desired color and may be dried before the same is fed into the textile machine. This operation consumes only a few seconds and requires no skill.

Accordingly, it is an object of the invention to provide an apparatus by means of which one or more threads supplied to a textile machine such as a weaving machines, knitting machines, sewing machines or the like may be dyed together in any desired color and dried thereafter before the same are supplied tothe machine.

It is another object o the invention to provide an attachment for textile machines, and the like which allows to save considerable time while sewing or knitting articles comprising threads or yarns of different colors.

It is a further object' of the invention to provide an attachment for textile machines and the like which allows to increase the output of the individual machine.

It is still an object of the invention to provide an attachment for textile machines and the like which allows to save thread or yarn. In sewing machines and the like used heretofore the' thread (Cl. dent) had always to be threaded again ir a thread of a dierent color had to be used. This operation is not only time consuming but causes a wastage oi thread. A

it is still a further object ci the invention to provide an attachment for textile machines and the like which allows to select the correct color for the thread without fail and which thus increases the safety ot operation of the sewing machine.: 4

it is still another object of the invention to provide an attachment for textile machines and the like which cbviates the necessity to keep a large number ci reels containing threads of various colors in stock. By the use of my improved attachment for textile machines and the like the manufacturer needs only keep white thread oi standard quality in stock. This has the further advantage that the quality of the thread of any color will always be the same while it may he sometimes dimcult to procure the same quality of thread in all necessary and desired colors. Also, if only a small quantity of thread of a certain color is required it is not necessary to buy reels of thread having the desired color which may' usually be obtained in large quantitles only.

With my improved attachment for textile machines it is possible to weave a small lot of fabrics such as handkerchiefs showing a new design in a new color` and to weave other fabrics in a diderent color if desired.

Heretoiore the entire warp of the loom had to be dyed before use while with my new apparatus it is possible to dye the warp on the loom and thus to obtain different shades on the same warp. In accordance with my invention itis possible to dye the thread, yarn or the like on the knitting machine and thus to avoid the necessity to tie the threads together. Heretofore, it has not been possible to knit hosiery such as stockings or socks having diierent colors without tying the individual threads of different colors. Also, in colored socks as made up to now long threads may be observed in the colored socks where the threads have been tied together.

Accordingly, it is still an object of the invention to provide an attachment for knitting machines and the like which allows to produce a better and cheaper product.

With these and other objects in view, the invention comprises the specifically described andJ illustrated embodiments shown in the accompanying drawings, in which,

Fig. 1 is a front elevation with parts broken away of my improved thread-dyeing and drying device.

Though the embodiments of my invention shown in the drawings are designed for the use of a sewing machine it will be'understood by the man skilled in the art that my new attachment may also be applied to other types of textile machines such as knitting machines or weaving machines.

Referring more particularly to the drawings, in which similar parts are designated by the same reference characters, I designates a reel of thread or yarn T. Reel I is rotatably arranged on a thread carrier 3 having a customary construction. As shown in Fig. 1 an adjusting ring E provided with a set screw 1 is arranged on cylinder 2. Ring 6 may be moved lup and down on cylinder 2'and x the same may be turned so that reel I may beadjusted and xed in any desired position. On ring 6 one or more thread reel carriers 3 are arranged which support reel I. Uusually one or two reels will be sulcient because for customary sewing machinesl not more than two threads will have to be dyed simultaneously. However, e. g. for special sewing machines such as chain stitch machines, bttonhole machines,

overlock and underlock machines using several sewing needles four or more thread reel carriers will be required. It will be appreciated by the man skilled in the art that my improved device may easily be adapted for a plurality of thread reel carriers.

In order to dye the thread or yarn a plurality of bottles are provided each containing a dye having a suitable color. In the embodiments shown in the drawings six dye bottles 8 are provided. The dye bottles are preferably made of a heat resisting material and the same are provided with an opening 8 which is sufficiently large to introduce a fork which is adapted to dip the thread into the bottle.` A number oi' bottles III equal to the number of bottles 8 is provided for an after treatment of the thread if this should be necessaryv for the type of dyestuff used. Bottles III are similar to bottles 8 in construction and shape and the same are provided with an opening II. A heating means I2 is provided which preferably consists of an electric heating element in order to heat the dye bottles 8 and I0 if this should be necessary. It will be understood that, if required, onlyv bottles'8 may be heated or that bottles 8 and bottles I0 may be heated in such a manner that each has a different temperature. Between walls I3 which support bottles 8 and III a space I4 is provided which allows the air heated by heating means I2 to heat the bottles 8 and I0.

In order to dip the thread T unwound from reel I into bottles 8 and I8 the device described hereinafter may be used. Push button I5 actuates rod I 6 which in turn is connected to a transverse rod '25 fastened to bifurcated rod 5. Between wall 2B of the housing and the rod 25 spring I1 is arranged. Underneath wall 26 transverse rod I8 connects bifurcatedrrod 5. Rod I8 is provided with a sharp nose I9. At the lower end of bifui-cated rod 5 forks 20 are arranged which, when button I5 is pushed down, are adapted to dip the thread into one of each of the bottles 8 'and I0. Rear wall 21 is provided with a hinge 2I which is connected with a curved rod 22 having a shoulder 23. Spring 24 is interposed between wall 21 and rod22. Against the action of spring 24 shoulder 23 can be pressed by means of button 38 having a rod 28. It will now be evident that if it is desired to dip the thread into one of the bottles 8 and I0 it is only necessary to press the button I5 of the desired dye bottle. Nose I8 of the pressed button I5 while moving down presses curved rod 22 against wall 21 and thus releases nose I8 of the button I5 previously depressed. Nose I8 will now engage with shoulder 23 and forks 28 will dip the thread into the desired dye bottle. If release button 38 is pressed shoulder y23 disengages rod I8 and the spring I1 pulls fork 20 out of the bottles again. It will be understood that button '38 is only actuated if it is desired to release all forks 28. 28 and 38 are guiding members which guide the thread from the reel I through the dyeing device.

Cylinder 2 is provided with an opening 3l through which the thread T is threaded and thread T leaves the cylinder through opening 4. Threading needle 32 is provided to thread the thread T through the dyeing device. Switch 33 opens and closes the electric current for heating element I2.

Cylinder 2 is arranged as a drying device for the thread. For 'this purpose a heating element 34 having a switch 35 may be provided at the bottom of cylinder 2.

Walls 36 and 31 are preferably made of glass which makes it possible to inspect the bottles 8 and I8 without removing the same. Furthermore, it can be observed when a bottle is empty and the same may be relled.

Figs. 4 and 5 show a modification of my invention. In this modication two thread reels 4I and 42 are provided arranged on disk 43 which in turn is xed on cylinder 44. A drum consisting of cylinder 49 spacing disks 41 and 48 is rotatably supported on cylinder 44 by adjusting ring 50 which is provided with set screw 5I. Six bottles 52 are arranged on disk 48 and the same are fixed by means of `spring 58. Openings 54 are provided in disk 41 above each of the bottles 52. Dipping forks 55 are adapted to move through opening 54. Forks 55 are guided through tubes 58 andthe same are adapted to move through openings in upper disk 41 and lower disk 48. At the lower end of each fork 55 a handle 51 is rotatably arranged and provided with nose 58. Nose 58 engages with flange 59. In order to prevent a rotary movement of forks, 55 the same are provided with a guiding recess which cooperates With a nose which may e. g. be arranged in disk 41. Thus forks 55 will always have the correct position In regard to opening 54. If handle 51 is turned nose 58 disengages ange 59 and handle 51 moves downwardly until the same rests upon plate 15. At

the same time the selected fork 55 moves through opening 54 and dips into its appertaining bottle 52. It will be noted that each bottle containing a distinct color is provided with its own dipping fork 55 in order to prevent that the dyestuil' remaining on the dipping fork contaminates the dyestuif contained in another bottle. By turning drum 41, 48, 49 any desired bottle 52 may be brought under the thread T.

i. Adjacent and above disk 41 a fork-shaped sheet member 18 is immovably arranged on cylinder 44. Member 16 is provided with three openings 60, 6I and 82 and with ear 83. Member 16 serves the purpose to guide thread T through openings 60, 6|, 62 -and through ear 63 and opening 64 in order to provide the necessary tension of the thread. It is essential that member 16 with its ear 63 is arranged below the upper position of forks 55 because otherwise the thread T on member 16 will be gripped by the forks 55.

The selected dye bottle '52 as Well as its opening 54 must be brought into such a position that opening 54 is bisected by the thread between ear 63 and opening 64. This position is assured when handle 51 meshes with an o-pening provided in plate 15.

Thread T is threaded and guided as follows. The same unwinds from reel 4I and moves through ear 45, through openings 60, 6I and 62 and through ear 63. Now the thread is seized by fork 55 and dipped into bottle 52 Wherefrom the same moves through opening 64 into cylinder 44. In cylinder 44 the thread moves once or several times through ears 65 provided at the upper part of rod 61 and through' ear 66. Rod 61 having a knob 10 is provided in cylinder 44 /and the lower end of rod 61 is provided with disk 69 and Weight 68 having an ear 66. In order to thread thread T the same is threaded through ear 45, through openings 6D, 6I and 62 and through ear 63, opening 64 and 1l and through ear 12. Openings 64 and 1| are provided on cylinder 44. Now, rod 61 is lifted by means of knob 10 and disk 69 seizes thread T extending between openings 64 and 1| whereby thread T is pulled out of cylinder 44. Now, while rod 61 is outside of cylinder 44 the thread is Wound one or several times over ears 65 and 66. Weight 68 is adapted to move up and downl on rod 61.

If e. g. a Whitethread is desired the fork 55 will be in its upper position and the thread T will, accordingly, be longer. If one of the forks '55 is in its lower position as shown in Fig. l weight 68 will be in a higher position.

Cylinder 44 serves the purpose to dry the dyed thread and for this purpose, a heating element 13 is provided which heats the interior of cylinder 44 and a suitable number of openings 14 are provided to facilitate the circulation of the hot air.
