T o all whom it may concern.'

Bc it known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented an Improvement in Apparatus for Treating Textile Fabrics, of which the following description, in connection with the acconr panying drawings, is a specification, like letters o-n the drawings representing like parts.

This invention relates to apparatus for treating textile material, and, while it may be of general application, is intended more particularly for use in dyeing, bleaching, washing or boiling material, which may be in the forni of warp, either twisted or untwisted, or in the form of woven material, preferably passed through the apparatus in ropy form.

In order that the principles of the invention may be clearly understood, I have disclosed a single type or embodiment thereof in the accon'ipanying drawings, wherein,--

Figure 1 is a side elevation of one form of apparatus embodying my invention; Fig. 2 is an elevation of one form of traversing mechanism that may be employed in conneetionwith my invention; Fig. 3 is a longitudinal, vertical section taken through apparatus shown in Fig. 1; Figs. t and 5 are, respectively, a side elevation and a central vertical section of detail to be hereinafter referred to; Fig. G is a horizontal sectional view, taken through the apparatus above the squeezing rolls thereof; Fig. 7 is a similar view of a form of apparatus wherein material from separate seurces may be simultaneously passed through the apparat-us; Fig. 8 is a front elevation of the apparatus shown in Fig. 1; Fig. 9 is a rear elevation thereof; Fig. 10 is a detail in vertical section of a slightly modified form of apparatus; Fig. 11 is a transverse, vertical section taken through the vat and one of the liquid oirculating rolls therein; Fig. 12 is a perspective view of one of said liquid circulating rolls; Fig. 13 is a transverse vertical sect-ion, taken through the liquid circulating roll shown in Fig. 12; and Fig. 14 is a side elevation of the preferred form of adjusting means for a squeeze roll or rolls.

The apparatus herein disclosed is adapted for treating textile material which is passed through a vat, the character of liquor wherein depends upon the nature of treatment to which the material is to be subjected. If woven cloth is to be treated it is preferably passed through the machine in ropy form, but without twist. If warp is to be treated it may be passed thro-ugh the machine either with or withouttwist. By twisting the warp, prior to or at the time of its delivery to the apparatus, the warp is preserved more perfectly for handling, and the use of a thread wrapped spirally about the warp is avoided. If the warp be twisted, the twist may be taken out after or before drying, or at the beamer. In the present embodiment of my invention I have represented an apparatus adapted to treat twisted warp, but it will be understood that if noirtwisted warp or woven fabric be employed the same is delivered to the vat from any suitable and preferably stationary source.

Referring more particularly to the drawings, and iirst to Figs. 1, 3 and G thereof, the warp which is to be treated is preferably deposited in a bag 1, the upper edge whereof is supported by hooks 2 upon a ring 3 which is supported by upright rods fl rising from a base plate 5, and after being passed about or suitably connected to the ring 3 are preferably removably connected to a sleeve G (see Figs. l and 5), rotatably supported in a split bushing 7 formed with or extending from a bracket 8 laterally eX- tending from one of the uprights 9 of the apparatus, and preferably carrying one or more loosely mounted guide rolls 10.

The main or cent-ral portion of the apparatus is provided with a suitable base 11 (see Fig. 11) rising from which are the opposite uprights 9, connected overhead by a suitable cross member 12. Suitably supported upon the base 11, between the uprights 9, is a vat 13, of any suitable conmounted the liquid circulating` rolls, tiel guide rolls aud the squeeze rolls, to be more partii'fularly described.

Preferably, a series' of liquid circulating rolls is mounted in the vat ,t3 in such manner as to permit their removal through one or the other of the lateral walls of the vat. In Fig. 11 l have represented the lateral walls of lthe vat as provided with openings 14, closing' which are suitable caps 15, provided if necessary upon their inner faces with suitable packing and so connected with the walls of the vat as to permit their ready removal therefrom. lllhile this may be accomplish-ed in any suitable manner, herein (see Fig. 1) I have represented each cap as having a plurality of ears 16, arranged concentrically with the center of said caps and adapted to eiigage screws 17 and to be disengaged therefrom by a slight circumfercntial nnavemcnt of the cap. Preferably each of a pair of caps is provided with a bi-aaring 1S, wher in is rece-ed the shaft 19 of the liquid cir mating' roll 20 pertaining thereto, it being; apparent that. the openings 14 are of such size as to permit the removal of the liquid circulatinp` roll tl'irough either wall of the vat upon removal of the cap.

IVhile the liquid circulating rolls may be of any suitable character and construction, preferably, and as shown more clearly in Figs. 12 and 13, each roll is provided with end hubs 21 having spokes 22 radiating therefrom and connected with annular rims 23 which are connected to each other by set-s of circulating` blades 24, 25, arranged about the periphery of the roll and extending in a more or less radialdirection fr in the axis thereof. rthe blades 24 and are arranged in pairs, as clearly shown in Fig-rs. 12 and 13, the blade 24 of each pair extending inwardly a greater distance from the periphery of the roll than the blade 25 and the inner ends of the two bladesI being inclined toward each other as they extend inwardly. The blades 24 and 25 of each pair are spaced from each other, leavingv a passageway 2G for the liquid to pass between them, and the succeeding pairs of plates are also spaced from one another, leaving passageways 27 fo-r the entrance of the liquid from the exterior of the roll to the space within its periphery. The spokes 22, which connect the hubs with the periphery, are flat and inclined in a lateral direction, for the purpose of inducing a current of liquid from without through the end of the roll to the space within its periphery. The spokes at one end of each roll are inclined in an opposite direction from the spokes at the opposite end, thereby tending to force the liquid in such opposite end while the separate pairs of blades tend to direct a current outwardly through the pe riphery. The inner end of each blade 24 tends to scoop the liquid within the periphery of the roll as the roll advances in the direction of thc arrow shown in Fig. 13, thereby inducing a current of liquid outwardly through the space between the blades 4 and 25, and hence in contact with the inner surface of the rope, chain or strip of material 28 supported upon the periphery of the roll. The construction of parts is such that the liquid will readily flow in through the spaces 27 and will pass the blades 25 and be interrupted by the inner edges of the blades 24 and be caused to pass outwardly between the blades, thereby being` forced into intimate contact with the face of the goods, and after passing around the fabric or warp will again be drawn inwardly and so will alternately pass outwardly and inwardly through the periphery of the roll as the latter is rotated in the liquid within which it is immei-sed.

Supported by the walls of the vat and above and preferably between the liquid circulating' rolls 20 are suitable loosely mounted guide rolls 29, 29 which may, if desired, be provided with peripheral., axially extending` slats 30, 30. Between the guide rolls 2), 29 I preferably provide a pair of squeeze rolls 31, 32, of suitable construction, the upper roll 32 being carried by arms 355 pivoted at 34 upon uprights 35 extending from the frame in such manner as to permit the upper squeeze roll 32 to be thrown backwardly and out of action, or lifted for manipulation of the `goods. In advance of the forward `@guide roll 29 I preferably provide a pair of squeeze rolls 3G, 37, of suitable construction, the upper roll 36 being held in peripheral engagement with the roll 37 in any suitable manner. Herein, for the purpose, the shaft o-f the roll is journaled for vertical yielding' movement in the uprights 9, and, with the shaft of the roll at opposite ends thereof, engages leversy 38, whose inner, hooked ends 89 pass beneath pins 40 (see more particularly Fig. 14), serving as fulcra and which may be vertically adjusted by set screws 41. The outer ends of said levers are pivotally connected by rods 42 with weighted levers 43, pivoted at 44 upon the uprights 9. The construction of parts is such that with the varying thickness of material the rolls 36 may automatically rise and fall while at the same time squeezing the liquor from the material, after its passage. through the vat.

Preferably, in the use of the apparatus the material is passed repeatedly about the periphery of the liquid circulating),` rolls. represented in Fig. 12, and about the guide and squeeze rolls, it being;l thus treated any desired number of times before it finally issues from the vat. In order to guide and direct the material after it has issued from the squeeze rolls 36 and 37, and to return the with a worm wheel 90 carried by the shaft of the apron support and driving r-oll 82. In this manner the apron 80 is driven at preferaliily a low rate of speed, which may be varied as desired by shifting the belt 87 upon the cones 85 and 80 by any suitable belt shifter (not shown).

By the employment of a folder having long and short blades 77 and 78, the folds are alternately of unequal length, as represented at 97 and 9S in Fig. rlhis manner of folding the material permits it more readily to accommodate itself to the contour of the apron 80, as will readily be apparent.

Preferably, I provide a closure or cut-off for the lower end of the receiver 73, constituting means to interrupt the depositing of the material upon the apron 80. While any suitable means may be employed for this purpose, I have, in Figs. 1, 8 and S, represented a gate or gates 99, carried by arms 100 pivoted at 101 upon the outer wall of the receiver' 73. Vhen the gates are swung into their outer position, as indicated in dotted lines in Fig. 1, they may be there held in such position in any suitable manner` W'ere no means provided to interrupt the depositing of the material upon the apron 80, it would be necessary, if it were desired to redirect the material from the apron 80 back into the vat, to lead that end of the material first deposited upon the apron 80 back into the vat, with the objection that in such event the material would, upon its retreatment, pass through the vat in the same direction in which it passed therethrough upon its first treatment. Preferably, the material if it is to he retreated in the vat should be reversed in such retreatment, so as to equalize the action of the liquor thereon. This is desirable because of the fact that the liquor becomes gradually weaker and lessl effective upon succeeding portions of the material. It will be apparent that if it be desired to retreat the material issuing from the vat, or any desired portion thereof, the gate 99 may be closed (after severing the material) whereupon that end of the material last deposited upon the apron 80 may be redirected over the guide rolls 4:5 and -16 to the liquid circulating rolls and thence through the vatin the manner already described. In this manner I am enabled to reverse the direction of travel of the material without removing the same from the apron 80. The apparatus herein disclosed may also be used for flat goods. If it be desired to reverse such material, it is preferably carried back under the vat and thence up to the point of entrance and is again passed therethrough, after which it may be wound on a batch roll in the ord1 nary manner.

I have shown in Fig. 10 'a modified form of the apparatus wherein is provided a folder 102, having arms 108, 103, of equal length, which construction may be employed in connection with certain types of my invention, although it is not as c'liicient in action as the unequal armed folder 75.

If desired, I may provide means permitting the delivery of a plurality of ropes or chains of material simultaneously to the vat. In Fig. 7 I have represented means for accomplishing this purpose. Therein I have represented a pair of containers 104, 105, the latter being driven from the former by suitable sprocket mechanism 100. It will be understood that the containers may be suitably rotated if desired to twist the material in the event that it be warp. No change is required in the construction of the vat, nor parts cooperating therewith, excepting that the ropes 107, 108 are delivered centrally of the lateral walls of the vat, as represented in said figure, the rope 1.07 being gradually fed toward one end of the rolls and the rope 10S toward the opposite end thereof. In the event that a plurality of ropes of material are simultaneously treated by the vat, the receptacle 73 is provided with a preferably removable partition 109, thus providing two compartments in which the materials may be independent-ly folded and traversed, by a plurality of suitably operated pot eyes. It is apparent that this system of treatment of textile material may be extended by providing means for simultaneously treating more than two chains or ropes of material. `Preferably, a plurality of gates 99 are provided, as represented in Fig. 8, so as to permit the simultaneous treatment of a plurality of ropes or chains of material. It will be apparent that if two ropes of material be simultaneously treated one of them may be deposited upon the belt 80 and immediately drawn therefrom for further treatment in other apparatus, and that the other, after closure of its gate 99, may be redirected through the vat in a reverse di rection.

Having thus described one type or embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purpose of limitation, the scope of the invention being set forth in the following` claims.

Claims.-

1. Apparatus for treating textile material comprising a vat, a container for the ma terial to be treated, means to rotate said container, means to deliver the material from the container in the direction of the axis of rotation of said container, thereby to twist said material, and means to deliver t-he twisted material to the vat.

2. Apparatus for treating textile material comprising a vat, means for directing teX- tile material thereto, one or more liquid cirsame to the liquid circulating rolls, I have provided guiding means preferably in the form of rolls, and have so mounted the said rolls that in the event that undue slackness or tightness of the material in its passage through the vat tends to develop, I may readily correct the fault. While this may be accomplished in any suitable manner, I have, as shown in Figs. 1, 3 and 6, provided guide rolls 45 and 46, suitably supported by the uprights 9 and having at one end, and, if desired at both ends, means for inclining the axis of rotation thereof. In Fig. 1 I have represented adjusting and lock hand nuts 47, 48 for this purpose. If the material becomes too tight in its passage through the apparatus one end of either roll should be lowered, whereupon the material runs loosely. If the material becomes too loose, one end of either of the rolls 'should be raised.

Certain of the rolls may be driven in any suitable manner. Herein for the purpose I have represented a driving shaft 49, having thereon a pully 50 receiving power from any suitable source, and a sprocket 51 about Which passes a sprocket chain 52 passing about and driving a sprocket 53 carried by the squeeze roll 37. Preferably, the squeeze roll 31 is also driven, and for this purpose a sprocket chain 54 extends from a second sprocket 55 upon the squeeze roll 37 to and about a sprocket 56 upon the squeeze roll 31. The container 1 may be rotated in any suitable manner, thereby to twist the vrai-p as the same is delivered axially therefrom. Herein for the purpose I have provided the squeeze roll 31 With a second sprocket 57, connected by a sprocket chain 58 with a sprocket 59 upon a horizontal shaft 60, suitably mounted in the framing of the machine and connected by bevel gears or otherwise as shown in Fig. 1 With a short shaft having thereon a sprocket connected by sprocket chain G1 to the base 5 of the container 1, so as to rot-ate t-he samerat the desired speed.'

It will be apparent that the liquid circulating rolls 2O are rotated by the passage of the material about and in peripheral contact therewith, and that `in their rotation they suitably circulate the liquor as previously described. After the mate-rial has been passed the desired number of times about .the several rolls, it is directed from the vat and its rolls for further use. Preferably the material is folded and, at the same time, is traversed in a suitable receptacle. Herein, for the purpose, I have represented a. guide roll 62, loosely mounted in hangers 63 depending from .the cross member 12. The material, after passing about the guide roll 63, extends through the pot eye or ring G4 of aA suitable traversing apparatus, shown more clearly in Fig. 2, and which, if desired, may be of the type represented in my Patent, No. 402,274, April 30, 1889, and which need not be particularly described. rIhe pot eye and its support are mounted in suitable guideways G5, and are traversed by a sprocket chain suitably driven fr-om a shaft 67 suitably mounted in uprights G8 rising from the cross member 12. Fast upon the shaft 67 is a pulley 69, receiving power from the shaft 49 by belt 70, it being apparent that in the traverse of the pot eye 64 the material, in ropy or chainlink form, is traversed back and forth over and is dcposited into a suitable receptacle underneath. The material is conveyed and directed to the receptacle by means of a roll 71, fast upon the shaft 67. If desired, a guiding roll 72 may be located beneath the roller 71, and be driven in any suitable manner.

Any suitable receiver for the material may be employed. Herein I have shown a reA ceptacle 73, having an open upper end 74, into Which the material may be directed and be folded by a folder 75, which herein is formed as a blade, pivoted at 76 along a line at unequal distances fro-m the longitudinal edges thereof, so as to present blades 77, 78, of unequal length, for a. purpose to be more fully described. The folder is pivotally supported in suitable bearings in brackets 79, extending from one of the uprights 9.

Mounted beneath t-he receptacle 73, and, in effect forming a Wall thereof, is an inclined carrier preferably formed as an endless belt 30, upon which the material is deposited after its passage through the closed part of the said receptacle. The belt S0 is preferably mounted in such manner as to present a curved and forwardly extending traveling surface to the materia-l, which is received thereon in folded form and from Which it may be readily removed for further treatment in other apparatus or 'from which it may be returned to the vat for retreatment. Herein the belt or apron 30 is mounted upon rolls 81, 82, and 83, suitably supported in a framing 84, one or more of said rolls being driven in any suitable manner.

Preferably, I provide means to drive the belt or apron 8O at different speeds. Herein, for vthe purpose, I have represented.
