Application filed December 20, 1911. Serial No. 667,029.

To all whom it may concern:

Be it known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Wicldletown, in the county of Middlesex and State of Connecticut, have invented an Improvement in Automatic Textile Receiving and Delivering Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to automatic textile receiving and delivering apparatus.

In order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof in the accompanying drawings, wherein Figure 1 is a vertical section from front to rear taken through the receiving and delivering apparatus; Fig. 2 is a vertical transverse section thereof upon the line 22 of Fig. 1; Fig. 3 is a side elevation, the tank being partially broken away, to show the liquor circulating mechanism; Fig. 4: is a front elevation of the apparatus; Fig. 5 is a view partially in vertical section and partially in side elevation of the apparatus having means for stopping the delivery of material; Fig. 6 is a vertical section from front to rear of a slightly modified form of apparatus; Fig. 7 is a vertical transverse section thereof; Fig. 8 is a vertical longitudina-l section of another and preferred form of the appartus; Fig. 9 is a vertical transverse section of a portion of the chute showing the adjustable sides; Fig. 10 is a detail in transverse section thereof; Fig. 11 is a horizontal section taken through the chute and showing the adjustable front wall; Figs. 12 and 13 are vertical longitudinal sections of still other forms of my invention; Figs. 14. and 15 show in. side elevation detachable guiding friction-reducing means for the chute, and Fig. 16 is a vertical longitudinal section of still another form of the apparatus.

This invention relates to apparatus for treating textile material in lengths and is an improvement upon the constructions shown in my Patents No. 108,388, August 6, 1899, No. 653,485, July 10, 1900, and No. 971,778, October 4, 1910.

As shown in my patents above referred to, textile material in length, such, for example, as cloth or yarn, has been piled or folded into the open, upper end of J or U shaped chutes, the material being treated either prior to or during its passage through said chute to the action of some suitable liquor, such, for example, as a bleaching, dyeing or other conditioning liquor. As disclosed in my said Patent No. 108,388, the front and rear walls of said chute were made of power driven aprons to facilitate the passage of the material therethrough. As shown in said Patent No. 653,485, I have facilitated the passage of the material through the chute by maintaining a flow of liquor sufficient to float the material therethrough. In the present application I disclose improved means for facilitating the passage of the material through the chute and in such manner as to prevent tangling of the material and to result in the discharge of the material in folds, preferably extending transversely of the chute and substantially normal to the walls thereof. In other words, the material is discharged without tangling or binding. The material is de livered into the open, upper end of the preferably substantially upright chute, and is gradually delivered therethrough. The chute is provided with a forwardly extending discharge portion. Owing to the general shape of the chute, it will be evident that the length of the rear and bottom wall thereof between the iii-take end and the delivery mouth is greater than the length between the same points of the front portion of the chute, and if both the front and back walls or portions of the chute presented the same frictional resistance to the onward movement of the material, then the material would become displaced from the folded condition substantially normal to the walls as described, and would become tangled and packed in the chute. The said greater length of the rear and bottom wall of the chute is substantially compensated for by the fact that it opposes less frictional resistance to the material contacting therewith than does the front portion of the chute and particularly the upper part of the front por-- tion. It will be apparent that particularly in the curved portion of the chute, the weight of the material accumulates more and more upon the rear and bottom wall until finally the entire weight is borne thereby. This increases the frictional resistance opposed to the onward movement of the material, and it is therefore important that this rear and bottom wall presents relatively less frictional resistance than the front wall or a substantial part thereof. In this embodiment of the invention this effect is secured by providing a ribbed construction of the rear Wall, as hereinafter more fully set forth. IVhile still securing the described result, I may and preferably do provide a portion of the front'wall with ribs or the like so as to facilitate the passage of the mass of the material without, however, impairing the relative frictional resistance of the front and rear walls,that is to say, even though the front wall be ribbed in part as referred to. The longer curved back or rear wall presents less frictional resistance than does the entire front Wall of the chute. Preferably also the chute is positioned in a tank adapted to receive treating liquor which may be a dyeing, bleaching or other liquor, and means are provided for circulating the liquor from the tank through the chute.

Referring more particularly to the drawings, I preferably provide a tank 1 of suitable material and proportions wherein I position a chute preferably of general J or U form. Said chute is herein represented as composed of a rear wall 2, the upper portion 3 whereof may constitute substantially a prolongation of the rear wall of the tank. The said wall 2 of the chuteis preferably composed of wood, the slats or pieces of which are herein represented as extending transversely of the chute. Said rear wall 2 is preferably of a general curved form, although a wall having substantially straight portions thereof at diflerent angles may be employed instead. I have herein represented the said rear wall as extending to the front of'the tank. The front wall 4 of the chute is preferably substantially vertical, and is represented as composed of wood. At the lower end of the front wall 4, I provide a movable member here shown as an apron 5 pivoted at 6, said apron resting at its lower end upon the goods or so constructed where hinged that it can not drop beyond a certain point, thus preventing undue friction against the material passing through the chute. The chute may be formed of any suitable material, and if desired of some material impervious to the action of bleaching, dyeing or other liquors, as, for example, cement or porcelain. The chute is composed of front, rear and two side walls, so that it is substantially rectangular in form.

' In order to reduce the frictional resistance between the material and the walls of the chute, and particularly the friction between the material and the rear and bottom wall of the chute, which is longer than the front wall, I provide fixed or stationary means for reducing such friction. For the purpose, I have herein represented a series of ribs 7, which may be of wood and which preferably extend from substantially the extreme upper end of the rear wall of the .chute to a point substantially in advance of the forward end of the apron 5, so that throughout its entire passage through the chute the material contacts at the rear wall with said friction reducing ribs. In order further to reduce the friction between the material and said rear wall, the said ribs 7 are preferably of gradually decreasing width from the upper to the lower ends in the directipn of the passage of the material through the chute,'and are also of gradually increasing height, as most clearly indicated in Fig. 1. Thus, as the weight of the material comes more and more upon the rear wall, the friction is reduced or compensated for by reason of the decreasing width of the said ribs. By increasing the height of the said ribs, I insure the holding of the material out of contact or substantially out of contact with the body of the back 2 between the ribs. Thus, in the passage of the material through the curved or forwardly directed portion of the chute the friction is more and more relieved or compensated for.

Preferably the apron 5 is provided at its under surface with longitudinally extending ribs 9 which may be and preferably are of gradually decreasing width and increasing depth in the direction of the passage of the material through the chute. At or near the lower end of said apron it may be pro-. vided with one or more transversely extending ribs 10 curved in cross section, or a loosely rotating roller or rollers may be substituted therefor, so as further to reduce the friction between said apron and the material.

The apparatus is particularly adapted for treating goods in lengths in a flat condition and in order to accommodate different widths of goods, the sides are adjustable in and out,that is, to and from each other,- and also the front 4 with its apron 5 may be adjusted in and out,that is, to or from the back 2, so as to facilitate the laying of the material in folds of the desired extent. It will thus be observed that the chute is composed of fixed or stationary parts, thus preferably avoiding the use of rolls.

If desired, I may employ short or sectional rolls at or adjacent the lower end of the movable apron 5, said roll sections being mounted between the ribs 9. V

In order to circulate the treating liquor through the chute and thetank, I provide suitable means to lift the liquor from the tank and deposit it inthe chute, and herein for the purpose have represented traveling buckets 11 carried by a beit or chain 12 passing about suitable drums or the like 13 suitably mounted in the framing. The

upper drum 13 is driven in any suitable manner from the main drive shaft. Preferably the buckets and chain are positioned. at one side of the chute and between the wall 14 thereof and the adjacent wall 15 of the tank, as indicated most clearly in Fig. 2. The elevated buckets are adapted to discharge into a trough or conduit 16,

. which discharges preferably into a recepconsiderable width from side to side and in such case I provide means for progressively laying the material in folds from side to side thereof, as well as from front to rear. In other words, I provide suitable means having a movement to and fro above the intake end of the chute, so as to deposit the material therein in folds, and I impart a suitable transverse movement to said folding means, thereby to progress the same back and forth from side to side of the chute. /Vhile any suitable means may be provided for the purpose, I have herein represented a main drive shaft 19 having thereon fast and loose pulleys 20, 21 driven from any suitable source. Upon said shaft 19 is mounted a suitable drum 22, about which the material 23 passes, said material being directed thereto from any suitable source and passing through a pot-eye or guide 24, to which transverse movement is imparted as hereinafter described. The material after passing about the drum 22 thence passes between feeding devices upon the lower end of two frames 26 pivoted loosely upon the shaft 19, and to which a to and fro or swinging movement is imparted by means of a crank disk 27 connected by link 28 to one frame 26 by a slot and pin connection 29, said slot permitting adjustment to vary the length of arc through which the frame 26 swings. The crank disk 27 is mounted in a suitable hanger 30 and is rotated by a sprocket pinion 31 by means of sprocket chains 32 from a similar sprocket upon the main shaft 19. Upon the lower end of the swinging frames 26 are rotatably mounted feeding rolls 34, 34, each having a sprocket pinion with which drivingly engages a sprocket chain 37 passing about a sprocket gear 38 on the main drive shaft 19,

and also about an idler 25 on the swinging frame 26. Preferably each of the feed rolls has upon its periphery a suitable number of slats 35. The material 23 passes about the drum 22 and thence between the feed rolls 34, 34. In the to and fro or swinging movement of the frames 26, the material may contact with both or first one and then the other of the feed rolls 34, 34, which are driven in opposite directions as indicated. In this manner the material is deposited in folds in the upper end of the chute. In order to traverse the material from side to side of the chute if desired, I provide any suitable mechanism, such, for example, as a sprocket chain 39 mounted upon suitable sprocket pinions 40, 41, the former of which is driven by bevel gearing 42 from the main drive shaft 19. To one of the links of the sprocket chain 39 is connected a rod 43 itself connected to the pot-eye 24, which is also provided with suitable rolls 44 guided in ways 45. The continued rotation of the drive shaft 9 reciprocates the pot-eye 24 from side to side in a manner not necessary more fully to describe.

If desired, I may provide means for stopping the delivery of the material in the event that it becomes tangled or clogged or for other reason it is delivered with too great tension. For that purpose I have in Fig. 5 represented the apparatus as provided with delivery rolls 46, 47 mounted upon suitable standards 48, so that said rolls may be in parallelism or angularly related to the main drive shaft 19 from which or any other suitable source said rolls may be driven. I have herein represented said rolls as having meshing gears 49, by which they are driven in unison, the shaft 50 of the lower roll being provided with fast and loose pulleys 51, 52, about which passes a belt 53.

At any suitable point intermediate the rolls 46, 47 and the tank and chute, I provide a stop device herein represented as comprising a lever 54 having guide rolls 55, 56, about which the material 57 passes as indicated to the delivery rolls 46, 47. Said lever 54 is pivoted at 58 upon the standards '48 and is provided with a belt 15 shifter arm 59. hen the material is clogged or tangled so as to become unduly tensioned, that arm of the lever 54 carrying the guide roll is drawn downward, thus shifting the belt from the fast to the loose pulley and stopping the rotation of the delivery rolls 46, 47.

Preferably the chute of the apparatus is of increasing diameter in the direction of the passage of the material therethrough, as

disclosed in my Patent No. 971,778. Instead however of gradually increasing the cross sectional area thereof, I may construct the chute in offset portions or sections. In this manner, the walls of the chute between the offsets may be parallel, thus providing a less expensive construction. In Figs. 6 and 7, I have represented such form of chute, wherein the front and rear walls of the chute are represented at 60 and 61 respectively. Each of these walls is provided with a suitable number of offset

portions

62, 62, the intervening parts thereof being preferably vertical as indicated. Similarly the side walls ea, 6% may be provided with

similar offsets

65, 65 with intervening parallel portions. The part of the chute thus provided with offset portions is preferably the upright part above the movable apron 5 of Fig. l.

The apparatus herein shown is adapted to treat material in rope or flat form, whether woven or in the form of warp. The material may be conveyed repeatedly through the chute if desired and may be treated by passing in successionthrough a series of chutes wherein different liquors are circulated if desired.

It will be evident from the foregoingdescription that the chute of the apparatus is composed wholly or entirely of fixed parts and that the friction of the material as it is conveyed therethrough is reduced to a minimum. Instead of treating the material in the chute with liquor as described, it is evident that the chute may be used as a time receiver or storage receptacle, from which it is drawn in any suitable manner, as from the delivery rolls 4:6, 47.

An important object of my invention is the provision of an apparatus adapted to receive, and from which may be'discharged or drawn, textile material either in a saturated or wet condition, or in a squeezed condition. That is to say, the apparatus is adapted to receive material which may be in rope or chain form or flat goods of suitable width, such material being treated either in the apparatus or previous to its entrance thereinto with any suitable conditioning liquor, such, for example, as a bleaching, dyeing, or other liquor, or just prior to the delivery of the material into the chute the conditioning liquor, of what ever nature, may be substantially expelled therefrom by the action of squeeze-rolls, so that while the material remains in the chute, the comparatively small amount of treating liquor yet remaining in the goods may continue to act thereon and, if desired, until the force of such treating liquor is exhausted. For example, the material prior to its delivery into the chute may be subjected to the action of a bleaching liquor and the greater proportion of this bleaching liquor may be expelled therefrom by squeeze-rolls prior to the delivery of the material into the chute. This permits the continued action upon the material of a weak bleaching liquor so that the time may be prolonged without injury to the material. Such injury would result if a bleaching liquor of full strength were permitted to act upon the material for any considerable periods, as, for example, during the storage of the material in the chute.

In my Patent No. 971,778, I have disclosed a chute wherein the rear wall thereof is provided with grooves for the down ward flow of treating liquor. These grooves, when the apparatus is particularly intended to act upon material in a wet or saturated condition, preferably terminate at or somewhat anterior to the bend of the chute, because the absence of the grooves beyond such point compels the liquor to penetrate or percolate into the mass of the material, whereas in the upper or grooved portion of the chute the liquor may work down at the edge of the material without fully penetrating thereinto. 7

When material is received in the chute in a Wet or saturated condition, it is less important to provide means for facilitating the passage of the material through the chute, that is to say, to provide frictionreducing means, than it is in cases where the material is received in the chute in a squeezed or substantially dry condition. As an important object in my invention is to adapt the apparatus to act either upon wet or substantially dry material, I have provided the chute with friction-reducing means which may be removed from the lower portion of the chute or rendered nugatoryin any suitable manner, thus adapting the chute in one form particularly for use in connection with wet goods, and in the other form particularly for use in connection with substantially dry material. 7

If the material treated be in rope or chain form, it is passed through they pot-eye 24 previously referred to, but if the material be in widths it is then passed about the drum or roller 22 without passing through the pot-eye 24, inasmuch as the goods are preferably of substantially the full width of the chute or J, and hence cannot or need not be traversed.

An important object of the invention, is the provision of a chute or apparatus from which moving parts are substantially eliminated, as such parts are apt to act injuriously upon the material.

In Fig. 8, I have shown a preferred form of my invention wherein the rear wall of the chute is represented at 66, and the upper part or substantially vertical portion of the front wall is represented at 67. Hinged or otherwise movably attached to the said front wall 67, as by means of a hinge 68,.is a former 69 generally similar to the apron or former shown in Fig. l, but preferably curved, as indicated. The hinge 68 is preferably substantially opposite the commencement of the curved portion of the rear wall 66. Preferably the curve of the former 69 is less than that of the rear wall 66, so that atthe lower end of the former, or point of discharge, the passage may be somewhat contracted as indicated, thus choking the material and preventing the sudden discharge of masses of the material into the tank 1 in a more or less tangled condition. The former 69 rests with its weight upon the material in the chute, and can yield upwardly and outwardly to the material to prevent undue choking thereof. I have provided a suitable adjustable stop 70, (here shown as a set screw), thus permitting any desired extent of swing or yield of the for mer 69. In other words, the stop or stops 70 may be so arranged that the former can yield until the cross sectional area of the chute at the lower end of the said former is at least equal to and even considerably greater than the cross sectional area at the upper end of the former. Preferably also, in this case, the upper or straight portion of the chute above the former 69, is of increasing cross sectional area both from front to rear and laterally, as indicated in Figs. 6 and 7. At its lower end, the former 69 may be provided with a preferably sectional roller 7 1, the sections whereof are between the ribs 72 upon the inner face of the former. These ribs 72 may be preferably of increasing depth and decreasing cross sectien as previously described, and the same is true of the ribs 78 upon the front face of the rear wall 66.

In order to circulate the treating liquor when the apparatus is intended to be used with wet goods. I provide any suitable liquid circulating device adapted to discharge the liquor in sufiicient volume into the upper end of the chute to act efficiently upon the goods. For that purpose I have, in Fig. 8, repre- 'sented a bucket wheel 7 L suitably pivoted at 75 and provided with opposite side flanges 76 between which are provided the pocketmembers 77, which dip into the liquor in the rotation of the wheel and discharge the same into the receptacle 78, which preferably extends about three walls of the upper end of the chute, as indicated in Fig. 8, so

that the liquor is freely discharged in suflicient volume into the chute. The wheel 74 may be driven either continuously or intermittently in any suitable manner, as from the main driveshaft 19. I

In order to assist in choking the material, or holding it in piled form at the discharge end of the chute, and to permit it to be drawn substantially uniformly therefrom, I preferably provide a loosely mounted roll 79, also indicated in Figs. 1, 5 and 6, about which the material may pass to the next icceeding apparatus, which may be another J or chute, or any suitable receptacle. I have here represented the material 80 as thence passing about an arm 54rof a stop mechanism which may be similar to'that shown in Fig. 5. Preferably I provide a hopper avail 8-1 to prevent the material falls bac up n that portion thereof tha i in the lower end of the chute, and, if desired, such hopper Wall may be mounted in slides in the side walls of the tank and may carry the roller 7 9, so that the hopper wall and roller, or either of them, may be bodily removed from the apparatus when it is not desired to use them. Or, if desired, and as here shown, the hopper wall 81 may be provided with an opening 82 extending substantially thereacross to permit the material to pass directly therethrough as indicated in dotted lines at 83.

The chute is adapted to receive flat goods of various widths, but preferably the width of the chute should correspond to the width of the material. Therefore, I provide means for adjusting the side walls of the chute to conform to the width of material that is being acted upon. This resultmay be accomplished in various ways. In Fig. 9 I have represented the outer or main side walls at 8%, and supplementary or inner side walls at 85, which may be moved bodily inward and held in adjusted position. I preferably provide brackets upon each pair of walls, and in Figs. 9 and 10 have represented upon each wall 84 an angular bracket 86, and upon each wall 85 a somewhat similar bracket 87 which have portions lying fiatwise against each other and preferably slotted, as indicated at 88, for the reception of one or more bolts 89, thus permitting the supplementary walls to be held fixedly in any position of adjustment. This form of my invention is particularly intended for use in treating fiat goods.

When the apparatus is intended for use with goods in rope or chain form, or in warp, I provide means for adjusting the front and rear walls relatively to each other, thus permitting any suitable variation in the to and fro movement of the folding apparatus. Preferably I adjust the front wall, and in Fig. 11 have represented the rear wall at 90, the side walls at 91, and the front wall at 92. Said front wall is provided at each edge with a suitable number of angular brackets 93, and the side walls with generally similar brackets 94 suitably slotted for adjustment and to receive bolts 95, thus permitting adjustment of said front wall in and out. WVhen the front wall is adjusted in and out, I also adjust the link 28 in the slot 29 in the frame 26, so that the extent of swing of the said frames 26 corresponds to the distance between the front and rear walls 92-90.

In Fig. 12 I have shown a form of the apparatus interchangeably adapted for use with either wet or squeezed material. Therein the rear wall is represented at 96 and the former of the front wall at 97. The inner face of the former is provided with ribs 98, or other suitable friction-reducing devices, and the upper portion of the rear wall 96 s provided with ribs 99 which preferably terminate at substantially the bend of the chute, as indicated at 100, so that if no means be provided upon the rear wall in advance of said ribs, then the chute is particularly adapted to act upon wet goods, as when said goods have passed beyond said ribs the liquor is forced to penetrate in between the layers or folds thereof. In order, however, equally to adapt the chute for use upon squeezed or mor nearly dry goods, I provide means preferably removable to facilitate the discharge or continuous passage of the material through the remaining portion of the chute. WVhile any suitable means may be provided to this end, I have here represented a number of rods 101 of metal or of any suitable material that will not be injuriously acted upon by the liquor. These rods may have their upper ends removably seated between the ribs 99 and their lower ends 102 positioned in sockets in the face of the rear wall 96.

Instead of providing ribs, such as heretofore described, I may, in each and every form of the apparatus, provide knobs, projections, or discontinuous formations, which act to hold the material away from. the surface of the wall or walls, and thus to reduce the friction between the goods and the said wall or walls. These knobs, projections or the like may be upon all four inner faces of the chute, or only upon the front and rear walls, or, if desired, merely upon the rear wall. These knobs may be in staggered relation if desired, and may be so arranged as to be removable in any suitable manner from the walls of the chute. In Figs. 13 and 15 I have represented a series of said knobs or projections 103 as mounted upon the curved slats 104, which, themselves, may be removably secured in any suitable manner against the inner face of the front wall or the rear wall, or the side walls if desired. In Fig. 13 I have shown the former69 as provided upon its inner face with ribs 7 2, but it is to be understood that the knobbed construction may be there provided if desired.

In Fig. 16 I have shown a chute similar, it may be, in general construction to that indicated in Fig. 8, and provided upon its inner face with any suitable friction reducing construction. and have also shown said wall 66 as provided with a suitable number of perforations 105 to'permit the circulation of the treating liquor therethrough.

The stop mechanism represented in Fig. 5 may be of any suitable character, and may be interposed between the chute or J and a succeeding chute or J, or between the chute and the next succeeding portion of the apparatus. In other words, said stop mechanism is preferably located between said chute and the squeeze or feed rolls of the next succeeding mechanism. If desired,

said stop mechanism may be interposed between a chute and connected to the traverse or pot-eye of the next chute, so that upon tangling of the goods, the mechanism is stopped as previously described. Preferably the belt shipper arm 59 is so constructed that it does not tightly engage the belt 53, thus permitting anydesired amount of variation in the tension of the goods without immediately shipping the belt.

The side walls of the chute may extend to the very bottom thereof, as indicated in Fig. 2, or may terminate at any suitable point thereabove, for example, at the commencement of the curved portion thereof, as indicated at 106 in Fig. 16, so that the liquor may circulate in all directions through the chute.

An important object of my invention is the provision of suitable means to choke the material at or adjacent the delivery mouth to prevent the goods floating off into the tank or entering thereinto in jerks, but'compelling them to be drawn ofi gradually and regularly by the feed rolls of the next succeeding mechanism.

While I have stated that the friction-reducing construction of one or more of the walls of the chute is particularly adapted for use in connection with goods in a squeezed condition, yet it is to be understood that such construction of chute may also be used in connection with wet or saturated goods, but that such construction is more particularly adapted for use in connection with the squeezed goods. It is also important that the friction-reducing construction of the lower or rear wall be continued to substantially the extreme end thereof, as in dicated in the several figures, as in this manner the piling of the goods in proper form is preserved throughout the choking thereof and to the very point from which the material is drawn to the next succeeding portion of the apparatus.

The swinging arms 26 may be oscillated at any suitable speed by change of the gearing by which such motion is imparted thereto. Preferably said arms are swung at a comparatively slow speed, and the speed may be such as to let the material accumulate more or less as it is laid back and forth in the upper end of the chute. I

When the goods are in what I have termed a squeezed condition, they are more or less sticky or adhesive, and, therefore, the provision of friction-reducing means such as ribs, projections or the like, is desirable. The weight of the column of goods in the upper portion of the chute may, however, be such as to assist in the delivery of the material therethrough, either in a squeezed or in a wet condition.

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

It will of course be understood that the means represented in Figs. 1 and 2 for folding and traversing the material, or any other suitable means to that end, may be provided with each and every form of the chute herein disclosed, the said folding or folding and traversing means being omitted from many of the figures merely to avoid duplication of parts.
