APPARATUS FOR DYEING OR BLEACHING.

SPECIFICATION formingpart of Letters Patent -N 0.7 35,183, dated August 4, 1903. Application filed October 19, 1899. Serial No. 734,071. (No'modeL) To all whom it may concern.-

Be it known that I, FRANKLIN A.WELLEE, a citizen of the United States, and a resident of Philmont,in the county of Columbia and State of New York, have invented certain new and useful Improvements in Skein Dyeing and Bleaching Apparatus, of which the following is a specification.

My invention relates to apparatus upon which skeins of yarn may be mounted and by which the yarn will be dipped into a vat or tank for dyeing, bleaching, or the like.

The objects of my invention are to provide an apparatus upon which the skeins of yarn may be conveniently mounted, carried into, and removed from the vat and reversed in position end for end at the bottom and top of the carrier with a minimum expenditure of time and by which the skeins will be held in suitable position to insure proper dipping and trailing in the vat and be automatically shifted on the skein-sticks in a manner to insure access of the liquid uniformly to all parts of the material.

To these ends my invention consists in a suitable carrier upon which skein-sticks may be mounted at suitable points, said carrier being preferably in the form of two parallel endless chains provided with adjustable clips for supporting the skein-sticks, guides within and outside of the vat under and over which, respectively, the carrier passes, and preferably consisting of sprocket wheels mounted upon a common axle and upon which the chains travel, and a drag bar or bars or retarding device over which the skeins of yarn drag during their circuit for the purpose of shifting and turning them upon the skein-sticks, said'drag-bars preferably consisting of sleeves surrounding the axles of the sprockets, so that the shifting and turning of the yarn occur at the points where the carrier passes its guides.

My invention further consists in the particular construction of the clips for holding the skein-sticks, each of which comprises a U-shaped bracket formed on one side with a diagonal slot providing a bearing for a skeinstick trunnion formed in the outer ends of its arms with seats or recesses to receive the edges of the chain links and adj ustably clamped upon the latter by means of a screw extending between its arms and a springkeeper mounted upon the clamping-screw as a pintle and held against the trunnion of the skein-stick when in the bearing through the medium of a spring.

My invention further consists in providing the skein-sticks with deflecting-guards at their ends, extending from the flanges diagonally inward in a manner to prevent the yarn riding up to the flanges and becoming entangled therewith orgetting beyond the same.

My invention will be fully understood upon reference to the accompanying d raw ings, in which- Figure 1 is a sectional end elevation of a vat or tank to which my invention is applied. Fig. 2 is a detail perspective, on an enlarged scale, showing a portion of one of thechains with the adjustable clips mounted thereon. Fig. 3 is an elevation in a plane at right angles to Fig. 1, showing a plurality of apparatus applied to a vat to illustrate the position of the skeins upon the carrier and the passage of one of the skeins over a drag-bar or retarding device. Fig. 4 is an enlarged detail view of one end of a skein-stick constructed in accordance with my invention, together with the supporting-clips on the chain, the clip being shown in vertical section. Figs. 5, 6, 7, and 8 are sectional views representing various forms of skein-sticks.

1 represents a vat or tank, and'2 a carrier in the form of parallel endless chains passing around upper and lower guides, of which the lower comprises sprockets-3, mounted upon an axle a in bearings 5 within the vat 1, while the upper guide comprises sprockets 6 upon an axle 7, mounted in suitable shaft-hangers 8. The lower bearings 5 are preferably made vertically adjustable in the vat through the medium of screws 9, threaded in brackets 10 and fixed by jam-nuts 11.

12 represents clips mounted at suitable points upon the parallel chains 2 to provide bearings for the trunnions of skein-sticks 13, upon which are mounted any suitable number of skeins A. I

14 represents drag-bars or retarding devices located in the path of the skeins in position to exert a dragging or turning effect upon the skeins as they pass. Said drag-bars are preferably located at the turning-point of which is well understood in the art. This result has generally heretofore been accomplished by the use of special mechanism for engaging the flanges or other parts of the skein-sticks at some point or points in their travel. I find in practice, however, that this result is fully accomplished by having the skeins pass over the drag bars or sleeves 14 in the manner suggested in Fig. 3. As this action takes place the inner side of the skein strikes the sleeve first and is tightened, while the outer side momentarily remains slack. The result is that there is a slight advancementof the skein in the nature of an endlessbelt travel upon the skein-sticks, which action is followed by the contact or stretching of the outer side over the drag-bar, and one side of the skein is caused to roll slightly upon the other and the strands are spread out, so that the whole efiect of the drag-bar upon the skein is not only a longitudinal shifting, buta turning or twisting. This action being repeated each time the skein goes around the drag bar or sleeve causes the strands of the skein to be effectually shifted to the fullest desired extent, and I am thus enabled by a most simple mechanism to accomplish that which has heretofore been accomplished only by the use of complicated mechanism.

The shape of the skein-sticks is not material and may be varied at will. Several suggested shapes are illustrated in Figs. 5, 6, 7, and 8.

The apparatus illustrated in Fig. 1 may be arranged in any desired number, as suggested in Fig. 3 the number being limited only by the length of the vat, as will be readily understood. The shafts 4, with their sprockets 3, act as idlers, motion being preferably imparted through the shafts 7, which are driven through the medium of a clutch 15, controlled by shipping-levers 16, fulcrumed at 17 from a main shaft 18, running transversely to the ends of the shaft7 and imparting rotation to the latter through small gearwheels 19 and large gear-wheels 20.

The construction of the adjustable clips 12 will be understood from Fig. 2, in which it will appear that each comprises a U-shaped bracket 22, provided in one of its arms with a diagonal bearing-slot 23 and [on the inner faces of the outer ends of its arms with recesses or seats 24. for the rounded sides of the links 21 of the carrier 2. The clips are clamped to the links 21 through the medium of screw 25, headed in one of the arms and threaded in the other. From the construction of the parts it is obviously an easy matresins ter to loosen the screw 25 slightly and to shift a clip 12 up or down on the chain at will. 26 represents a keeper pivoted upon the screw 25 through the medium of its bearing 27 and forced in a direction to hold the trunnion in the slot 23 by means of a spring 28, one end of which engages the keeper at 29, while the other engages beneath a fixed part of the clip, as shown at 30. The end of the keeper 26 protrudes beyond the clip, so that the trunnion may be readily inserted by forcing it up beneath the keeper and then into the slot. It is to be understood that the clips are made in pairs -that is to say, with their bearing-slots on opposite sidesso that when a pair of clips is placed upon the parallel chains their bearings will be opposed and for the further purpose of admitting the clips to be arranged in sets of four, with the diagonal slots of the clips mounted upon the same chain extending in opposite directions. This will be understood upon reference to Fig. 2, from which it will also be seen that the weight of the skein will hold the upper skein-stick trunnion in the diagonal slots by gravity, while the trunnions of the lower skein-sticks, which bear no weight, will be held in place by the keepers 26. It thus becomes practicable to adjust the clips and space the sticks apart, so as to allow slack in the skeins and permit them to make the turns around the drag bars 14. This relation between the clips continues after the chains round the upper guide and travel downward, for the parts are then completely reversed and the lower clips on the upward movement now become the upper clips on the downward movement and support the skeins, and their diagonal slots are in position to support the skeinsticks by gravity.

It is desirable in the treatment of skeins as above described to provide some means for preventing the strands riding up to and over the flanges 31 of the skein-sticks 13. To

insure against this, I employ diagonal guards 32, which extend from the flanges inward at an angle which will prevent the skeins riding up and which will keep the skeins at an ample distance from the flanges to prevent interference.

In practice all of the working parts of my apparatus are preferably made of bronze or other metal non corrosive in the chemicals through which they pass.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
