PATENT oFFrc E 4. Claims.

This invention relates to an apparatus for spot dyeing skeins of textile material, that is,

dyeing longitudinally spaced portions of said skeins either the-same or a variety of different colors or shades.

The invention broadly comprehends an apparatus of the character and for the purpose'set forth which includes means for sealing off and isolating one or morelong-itudinally spaced portions of one or more skeins of textile material Within dye receiving compartments, means for completely filling said compartments with dye solution of the same or different colors or shades so that said sealed off isolated skein portions are immersed in 'the' dye solutions, and means for removing the dye solutions from the compartments to permit of the unsealing and removal of the skeins from the apparatus or the shifting of the same withrespect thereto to dispose other longitudinally spaced portions in a position for sealed off isolation and dye ng.

More particularly the invention resides in an apparatus of this nature which includes a pair of separable blocks having a plurality of dye re- 25. ceiving recesses in the confronting faces thereof between which faces the skeins are arranged with portions thereof traversing the recesses, yieldable gaskets being provided'on the confronting faces of the dye blocks, framing the recesses 30. together with means for forceably compressing the gasket confronting faces into intimate seal-- ing contact to seal off" and isolate'the longitudinally spaced portionsof the skeins, with valved means for gravitationally supplying dye to and filling the recesses, valved means for'venti'ng. the

recesses and for indicating when the same are filled and valved means for draining the excessdye from the recesses after the skein portions have been impregnated.

The invention furthermore embodies means for introducing air pressure to the-dye receiving recesses when filled with the dye and sealed so as to more rapidly effect the impregnation of the skein portions and for subsequently effecting the removal of the excess dye and causing a more rapid oxidation or setting of the dye impregnated portions of the skeins whereby they may be removed.

Other features of the invention reside in' an 60. improved apparatus of this character by virtue of which the operations of positioning the skeinsfor dyeing, subjecting them to andthoroughly impregnating them with the dye, effecting the removal of the excess dye therefrom and caus- 553 ing the oxidizing: or drying of the dye impregn'ated portion or portions of the skeins to permit of their: removal, may be expeditiously accom-/ plished' without material loss of the dyeing solutions, while confining the dye more precisely to predetermined portions of the skeins.

Other objects of the invention are to provide an apparatus of this nature which is-notunduly' complicated either in its construction or mode of use, which is capable of economical production and assembly and which ishighly eflicient for its intended purpose.

Withthese and other'objects'in view; reference is now made to the following. specification and" the accompanying drawings in which: there' is disclosed one embodiment of the invention, while. the claims cover" variations and modifications falling withinthe scope of the invention.

In the drawings:

- vention'and' illustrating the skeinsin position for dyeing;

Fig. 2 is atopplan view thereof.

Fig. 3- is a. horizontal sectional view taken ap'-' proximately on the line. 3--3 of Fig. 1 and i1.- lustrating. the lower block swungto a position for facilitating the emplacement or removal of theskeins:

Fig; 4 is a vertical transverse sectional" view" taken approximately on the line 4--4 of Fig. 2;

Fig. 5 is a vertical sectional view taken approximately on a planeindicated by the line 5-5 in Fig. 2;

While obviously the apparatus may be employed-for dyeingoneportionof the length of one skein at one time, from a practical standpoint it is-herein illustrated and intended to be utilized. for. simultaneously dyeing a plurality of longitudinally spaced portions of eachof a. number of skeins, a variety of different colors or shades.

Referring to the drawings by characters of reference, l0 designates the base of the apparatus which is provided with laterally spaced upright supports II and IZhaving, horizontal upper supporting surfaces l3 and I4. A pair of arms l5 and I6 aresecured" to the'supports II and [2 respectively and protrude upwardly therefrom, the upper ends'being provided with reduced threaded upper extremitiesl-'! which receive thereover the apertured terminals of a cross. head I8 having acentral hub l-B provided with a vertical internallythreaded bore 20. A threaded shaft 21 engages with the: bore 20-, is provided with a manipulating wheel 22 at its. upper end and is connected at 1 its lower end by:

a swiveled connection 23 with a pressure plate 24 which is mounted for guided vertical movement on the arms I and I6 which extend through

guide openings

25 and 25 in the pressure plate.

The apparatus further includes a pair of

dye blocks

30 and 3|, the former being hereinafter termed the lower dye block and the latter the upper dye block. The lower dye block 30 is provided with a vertical opening 32 through which the arm l5 extends and normally rests upon the upper supporting surfaces l3 and M of the supports H and I2, but is capable of being swung to a position to disengage the upper surface [4 of the support 12 so as to permit of the positioning of the skeins thereover in surrounding relation thereto. The upper dye block 3| is mounted for vertical guided sliding movement on the arms i5 and it which extend through vertical guide openings 33 and 34 and said upper dye block is detachably connected with the pressure plate 24 by suitable means, such as the swinging hooks 35 fulcrumed on the pressure plate 24 and engaging with eyes 36 on said upper dye block.

As illustrated, the confronting faces of the upper and

lower dye blocks

30 and 36 are provided with a plurality of confronting mating recesses 4i) and M, 42 and 43, and 44 and 45, it being obvious that one or more pairs of mating recesses may be provided in said dye blocks within the scope of the invention. It will also be apparent that the recesses may be varied in size as well as the number employed and that the dye :locks may be of any practical length depending upon the number of skeins which are to be simultaneously dyed by the apparatus.

The confronting faces of the blocks are each provided with yieldable sealing gaskets 46 and 41 which are provided with mating slots 48 con donning to the contour of the recesses so that the same are framed by the gasket material which is preferably a good grade of Para rubber and which is secured in place in any suitable manner, such as by screws or other equivalent fastening :means '29 which are threaded into wooden plugs 55 counter-sunk in depressions in the confronting faces of the dye blocks.

The skeins of textile material, which are designated by the reference character S, are preferably arranged in surrounding relation to the lower dye block 30 as particularly illustrated in Fig. 5 of the drawings, so that the upper leads thereof traverse the upper face of the lower dye block with longitudinally spaced portions P thereof traversing each of the recesses 45), 42 and 44. The emplacement of the skeins S is effected by swinging the lower dye block to a position out of contact with the support l2, as shown in Fig. 3 of the drawings. After the skeins have thus been emplaced, the dye block is swung to its normal position resting upon and supported by the upper surfaces l3 and I4 of the supports H and H2. The upper dye block which has been elevated to permit of the emplacement of the skeins, is then lowered by means of the threaded shaft 2i and the gasketed lower surface of the upper dye block is forceably compressed against the gasketed upper face of the lower dye block to seal off and isolate the portions P of the skeins S in the mating dye receiving recesses 40 and ii, 42 and 43, and 44 and 35, it being understood that the yieldability of the gaskets 46 and 41 will permit them to be compressed and intimately seal about the portions of the skeins which are located therebetween and prevent escape of the dye solution from the dye recesses.

In order to provide means for gravitationally supplying and introducing the dye to the dye receiving recesses, a dye reservoir 55 is provided for each pair of mating recesses which is located above the recesses and each reservoir has leading downwardly therefrom a conduit pipe 56 controlled by a shut off valve 51. The conduit pipes 56 are respectively connected to and communicate with ports 58 leading to the corresponding recess in the lower dye block. Each recess of the upper dye block 3| is provided with a port 59 with which a conduit pipe 60 is connected and communicat'es. The pipes 60 are each provided with a T coupling 6 l, the vertical branch of which connects with a vertical pipe 62 having a cut off valve 53 from the top of which a combinedtransparent sight and vent tube 65 extends upwardly. The remaining horizontal branch of the T coupling E5! is connected with a nipple 65 having a check valve 86 which opens inwardly and closes outwardly. Each nipple is adapted to have attached thereto an air pressure hose, not shown.

The lower end of each reservoir 55 may be provided with a drain valve 61 and the conduit pipes 56 adjacent "leir connection with the lower valve block have interposed therein a T connection 38, the lower vertical branch of which connects with a drain pipe 69 having a cut off valve In op ation, assuming that the skeins have been pOSltiGllCd and clamped between. the dye blocks, as shown in Fig. 5, so that the portions P have been sealed off and isolated in the dye receiving compartments defined by the mating recesses, the valves El and 15 being closed, the op uc: opens the valves 63 and 51. The dye soluhons in the reservoir which may be either of the same or different colors or shades, gravitationally run into the dye receiving compartments.

defined by the mating recesses, completely filling the same as they are vented by the air escaping through the ports 59, the pipes 59, T coupling Si, pipes 52, through the opened valves 63 and the combined sight and vent tubes 84. When the dye shows in the sight tubes 64, the operator cuts off the valves 53 and 5'! thereby sealing up the dye system completely. Air pressure may now be admitted through the nipples 65 and check valve 65' to set up a pressure within the system so as to force and expedite the impregnation of the skein portions P with the dye. The drain valves iii are then opened to permit the dye to be discharged from the system through the drain pipes 69 where the dye is caught into receptacles a! placed thereunder to receive the same, the air pressure assisting in a rapid discharge and at the same time effecting a more rapid oxidation and setting of the dye in the impregnated skein portions P. The drain valves it? are then cut off and the dye solutions in the receptacles H are poured back into the reservoirs 55 so that the operation may be repeated.

As illustrated, the lower dye block 3%] is provided with guide rollers 75 around which the skeins are trained and the supports ll and 2 at the front are provided with vertically adjustable brackets 'i'G which are normally drawn downwardly by contractile springs "H. A removable roller 78 is mounted for rotation in the brackets and is adapted to be turned by means of a crank '59. The skeins are trained around the roller 78 which is employed as a means for shifting the skein to for dyeing.
