14 Claims. (Cl. 19-159) This invention relates to a coiler which can be used with sliver forming apparatus employed in the textile machinery field and which coiler functions to coil the sliver in a predetermined manner in a sliver can.

An object of the invention is to provide an improved and novel coiler of the type above referred to and wherein the rotatable head of the coiler is supported for its rotative operative movement in an improved manner such as to reduce to a minimum friction and wear between the relatively rotatable parts of the coiler.

Another object of the invention is to provide a coiler wherein the rotatable head is so mounted in its support that the contacting surfaces of said head and support can be properly lubricated and the lubricant confined to obviate danger of it getting on the sliver while at the same time radial loads to which the rotating head may be subjected are adequately taken by antifriction bearings.

. Another object is to provide a coiler wherein the part which supports the rotatable head can be readily removed and replaced as a unit in case undesired wear thereof occurs.

Another object is to provide in a coiler a rotatable head wherein the calendering roll which is mounted on the swingable axis leads or precedes the roll that is mounted on a fixed axis during the rotation of the head whereby the delivery bushing for the sliver can be set for a constant clearance relative to the surfaces of the calendering rolls regardless of the thickness or dimensions of the sliver.

A further object of the invention is to provide in a coiler a rotatable head wherein the delivery bushing for the sliver is so formed as to be advantageously assembled in the head and is formed of separable sections either one of which could be replaced if necessary, and which fact enables extremely accurate relationship to be obtained between the calendering rolls and the bushing and the bottom of the head and the lower end of the delivery bushing.

A further object of the invention is to provide a coiler wherein the sliver delivery bushing mounted in the rotating head has a cooperative relationship with the calendering rolls in the nature of a doctor blade relationship and wherein the bushing at its sliver receiving end is provided with a rectangular orifice enabling it to more eflectively cooperate with the sliver passing between the calendering rolls and into the bushing.

A still further object is to provide in a coiler an improved condenser bushing mounted in the rotating head and located-above the calendering rolls carried by the latter and so formed that it will prevent flare-out or dispersions of the fibers forming the sliver and passing through the condenser bushing.

Another object is to provide in a coiler the combination of the improved features hereinbefore referred to and which functions conjointly' to render the operation of the coiler more efficient in the passage of the sliver therethrough and in the shaping of the same and in the coiling of the sliver in the sliver can.

ice

Further and additional objects and advantages present in the invention and not hereinbefore referred to will be come apparent hereinafter during the detailed description of an embodiment of the invention which is to follow and which embodiment is illustrated in the accompanying drawings forming part of this specification and wherein,

Fig. l is a side elevational view of a portion of a gill box to which the coiler embodying the invention is attached at the output end of the gill box.

Fig. 2 is a horizontal sectional view through the coiler and is taken substantially on line 22 of Fig. 1 looking in the direction of the arrows.

Fig. 3 is a vertical sectional view through the coiler and is taken along irregular line 3-3 of Fig. 2 looking in the direction of the arrows.

Fig. 4 is a vertical sectional view through the condenser bushing, the calendering rolls and the delivery bushing of the rotatable head of the coiler and is taken substantially on line 4-4 of Fig. 3 looking in the direction of the arrows.

Fig. 5 is a fragmentary plan view taken substantially on line 5-5 of Fig. 3 looking in the direction of the arrows with certain parts omitted, and

Fig. 6 is a fragmentary sectional view taken substantially on line 6-6 of Fig. 2 looking in the direction of the arrows but with the swingable supporting bracket for the leading calendering roll of the rotatable head shown in full.

The coiler embodying the invention is shown for illustrative purposes as used with a gill box but it will be understood it could be used with other types of sliver forming apparatus. The gill box is indicated generally at 10 and it will be understood that the sliver shown at 11 is formed therein and moves out of the output end of the gill box and into the coiler 12 embodying the invention to be coiled thereby in a predetermined manner in the sliver can 13 which is rotatably supported beneath the coiler. The general arrangement just referred to is well understood in the art and need not he explained in greater detail.

The coiler comprises a supporting base 14 which may be secured to a supporting frame portion of the gill box. The base 14 is provided with a circular opening, the' circumference of which in this instance has a shouldered bearing flange 15. A bearing supporting ring 16 for the rotatable head of the coiler interfits the opening in the base 14 and is provided at its upper end with a circum ferential flange 17 that interfits and bears upon the shouldered flange 15 of the supporting bearing ring 14. p

The bearing supporting ring 16 may be secured against rotation relative to the base 14 by any suitable means, not shown, but which will be understood. It will be seen that the bearing supporting ring can be removed from the base 14 and replaced by a new supporting ring should it be desired. The bearing supporting ring 16 is substantially cup-shaped in configuration but. has the bottom thereof provided with a central opening for a purpose later to become apparent.

The bearing supporting ring 16 just inwardly of the central opening referred to is provided with an annular channel or groove 18. The rotatable head of the coiler includes a bearing base 19 which rotates within the central that the weight of the head is supported by the' engageQ ment of the ri'b'20with the bottom of the groove 18. It will also be seen that lubricant can be inserted into the ea groove 18 which acts as a bearing and lubricant well and where it will be confined against any likelihood of reaching the sliver passing through the coiler and which will act to lubricate the contacting surfaces of the rib 20 and groove 18.

The bearing base 19 upwardly of the rib 71.-ii as viewed in Fig. 3 has on its circumference a ring gear 21 which meshes with a drive gear 22 later to be referred to. The supporting bearing ring 16 circumferentially outwardly of the channel or groove 18 is provided with a plurality of circularly spaced stud mounted sealed antifriction bearings indicated in their entirety at 23 and engaging the circumference of the bearing, base 19 of the rotatable head just below the ring gear 21.

. It will be observed that in this instance three-of the antifriction bearings 23 are shown and which are equally spaced circumferentially with one of said bearings being directly opposed to the thrust exerted by the gear 22. The antifrict'ion bearings 23 absorb the radial load exerted by the gear 22and any radial thrust occurring during the rotation of the head, and, hence said hearings fnnction to maintain at aminimum wear between the head and its supporting bearing ring and, in addition, substantiab 1y reduces friction losses which might otherwise occur. Also the thrust bearings maintain the spaced relationship between the sides of the rib 249 and groove 18.

Referring to the drive gear 22 it will be understood that a portion of the bearing supporting ring 16 is cut away to accommodate the gear 22 in its intermeshing engagementwith the ring gear 21. The gear-2 2 is fixed to a 1 vertically extending shaft 24 that is rotatably supported in spaced bearings 25 and 26 mounted in a portion of the base 14. The shaft24 has fixed on its upper end a bevel gear 27 in'terrneshing with a bevel gear 28 fixed to ahorizontal shaft 29 which is driven from a drive source in thogear box not shown.

It is well to mention here that the rotatable base 3% for the sliver can 13 may be rotated oppositely from the direction of rotation of the head from a power source in the gill box byv a suitable driving connection indicated generally M31 in Fig. 1 but which need not be further described herein as it forms. no part of the present invention.

The bearing base 19 of the rotatable head of the coiler'is provided with upwardly extending supporting

wall portions

32, 33 and 34.. The

wall portions

32 and 33 adjacent their upper endsare provided with antifriction bearings which rotatably support a shaft 35 having fixed thereto a gear 36 and a beveled pinion 37, which gear and pinion are, shown in Fig; 3 as formed integral with each other.

Displaced from the shaft 35 the.

walls

32 and 33 retatably support in suitable bearings an idler shaft 35% which has fixed to it an idler gear 39 and which idler gear constantly meshes with the gear 36 on the shaft 35 and a gear 40 fixed to a shaft 41 below the shafts 35 and 38 and rotatably supported in suitable bearings in the

Wall portions

32 and 34 and passing through an opening in the wall portion 33.

The shaft 41 of the right of the wall portion 34 has fixed to it a driven, calendering roll 42 which, as will later be seen, is the trailing calendering roll during the rotation of the head of the coiler.

The driven calendering roll 42 adjacent to the wall portion 34 is provided with a gear 43 which meshes with a gear 44 on the idler leading calendering roll 45 which is rotatably mounted on suitable antifriction bearings 46 carried by a shaft 47 that is nonrotatably mounted in a rockable support 48. The support 48 has a pair of cars 49 spaced longitudinally of the support and straddling a thickened portion of a plate 50. The plate 50 is secured to a boss extending upwardly from the 'bearmg base 19 by means of a pair of securing screws 53 and locating dowel pins 52. The thickened portion of the plate 50 is provided with a bore aligning with openings formed in the ears 49 and a bearing hinge pin 53 is mounted in said openings in said bore, where-fore the support 48 can swing about the pin 53 as an axis to move the leading calendering roll 45 toward and away from the circumference of the trailing calender-ing roll 42. Means is provided for exerting a spring load on the support 48 to maintain the leading calendering roll 45 in engagement with the circumference of the trailing calendering roll 42 with a predetermined pressure but still allowing the sliver to pass between the rolls.

The means just referred to comprises an upwardly extending threaded supporting boss 54 formed on or secured to the plate 50 and having screwed therein the threaded nipple 55 of a tubular housing 56 for a plunger 57 which projects outwardly of the nipple and engages in a recess formed in the support 48. The plunger 57 at its inner end within the housing 56 is provided with a flange forming an abutment for one end of a coil spring 58 mounted in the housing and having its other end abutting a thread ed adjusting cap plug 59- which when screwed to position will cause the spring 58 to impart a predetermined spring load on the-plunger and against the support 48.

A dome-shaped cover oft-for the coiler is rigidly secured to the supporting base 14 and the bearing supporting ring 16. The cover 60 centrally of its top is provided with an opening into which interiits a shouldered hub portion of a bevel ring gear 61 that is held against rotation relative to the cover 60 by means of locking screws 62 passing through the cover and into the ring gear 61. The ring gear 61 meshes with the beveled pinion 37 on the shaft 35 and hence it will be seen that when the rotatable bearing base 19 of the head is rotated through the gears 22 and 21 in a counterclockwise direction the pinion 37 will roll around the gear 61 to rotate shaft 35, gear 36, idler gear 39, gear 40 and shaft 41 to cause rotative movement of the trailing calendering roll 42 and therefrom rotative movement of the idler leading calendering roll 45.

it is well to point out at this time that while the rotatable head of the coiler will rotate in a counterclockwise direction, that the drive to the can supporting base 30 is such that said base and the sliver can mounted thereon will rotate in a clockwise direction,

The hub portion of the gear 61 is provided with a central opening in which is mounted a trumpet bushing 63 while secured in position at the inner side of the gear 61 is a shield 64 to prevent fibers from the sliver as the latter enters the coiler through the trumpet from contacting the teeth of the gear 61 and the pinion 37 that meshes therewith.

A supporting plate 65 is secured in horizontal position to the internal upstanding wall portion of the head and extends to a position wherein it overlies the calendering rolls 42 and 45. The plate 65 above the nip point of said rolls is provided with a slot 66 extending inwardly from the end of the plate and interfitting with a locating boss 67 formed on a condensing bushing 68. The condensing bushing 68 is provided on its opposite sides with flanges 69 overlying and secured to the upper side of the plate 65 by suitable securing screws. The condensing bushing 68 is provided with an elbow form of passage therethrough in that it has an upwardly inclined inlet portion 68a and a vertical outlet portion 685 that overlies the nip of the

rolls

42 and 45. This type of condenser bushing through which the sliver passes from the trumpet 63 to the calendering rolls prevents the flare-out or dispersion of the fibers from the sliver and directs the slivers vertically downwardly to the nip of the

rolls

42 and 45.

The plate 65 at the end mounting the condensing bushing 68 has its longitudinal side edges recessed as indicated at 70 and said plate inwardly of its recessed longitudinal edges is provided with parallel longitudinally extending grooves 71. Angle'plates 72 are located in the recessed portionsof the longitudinal edges 70 of the ass ssin plate "65 with the long arm of the angle platesfprojedti'n'g vertically downwardly and the horizontal arms 72a thereof overlying the plate 65 and provided at their ends with downturned flanges fitting into the grooves 71. The angle .plates 72 have secured on the sides of the long arms thereof adjacent to the

rolls

42 and 45 doctor blades 73. The doctor blades 73 extend the axial length of the rolls '42 and 45 and their lower inner edges ride in contact with the circumference of said rolls and are held in such contact by means of leaf springs 74 secured to the upper side of the plate 65 and overlying the horizontal arms of the angle plates 72.. In eifect the plates 72 and the doctor blade 73 carried thereby are hinged at the locations where the flange on the horizontal arms 72a of the plates engage in the groove 71 and are urged by the-springs at all times inwardly into contact with the circumferences of the rolls. The doctor blades 7-3 function to remove from the circumferences of the rolls any fibers from the sliver passing between the rolls and which may have adhered to the circumferences of the rolls.

Beneath the nip of the

rolls

42 and 45 the bearing base 19 of the rotatable head mounts a delivery bushing through which the sliver passes to be coiled by the counterclockwise rotating head in the clockwise rotating sliver can. The delivery bushing just referred to is formed of two

separable parts

75 and 76 for apurpose'now to be pointed out. The part 76 of the delivery bushing is the lower part as viewed inFig. 4 and includes a rectangular portion interfitting a rectangular opening in the bearing base 19 and havirrg at its upper end a peripheral flange which overlies aboss on the bearing base 19 and can be secured thereto. It is important that the lower end of the part 76 of the delivery bushing be located accurately flush with the lower surface of the bearing base 19 so as not to project therefrom to a position where it will hook onto the sliver passing from the bushing to the sliver can during the rotation of the coiler head base. Also when the sliver has been coiled in the can almost to the top of the can it is essential that the bottom of the rotatable head and the lower end of the bushing part 76 be accurarely flush with each other. In mounting the part 76 of the delivery bushing in the bearing base 19 the required relationship of the lower end of the part to the undersurface of the base can be readily obtained by using, if necessary, suitable metal shims interposed between the upper end of the boss of the base and the underside of the peripheral flange on the upper end of the part 76. The upper part 75 of the delivery bushing has at its lower end a peripheral flange which overlies the upper end and flange of the lower part 6 and can be secured to the flange of the part 76 and to the boss of the base 19 by suitable securing screws 77 passing through the flanges and into the boss.

The part 75 of the delivery bushing above the peripheral securing flange is of truncated pryamidal cross section so that its upper edge around the rectangular hole in the upper end of the part 75 will ride in close proximity to the circumference of the trailing roll 42 and will have a doctor blade action on said roll.

Provision is made for slight lateral adjustment of the part 75 by providing a clearance between the openings in its peripheral flange and the securing screws 77 so that the upper edge of the part can be properly located against the circumference of the roll 42. Also the part 75 can be adjusted as to its vertical position to properly position its upper edge with respect to the circumference of the roll 42 by interposing suitable metal shims between its peripheral flange and the peripheral flange at the upper end of the part 76. Therefore the delivery bushing can be accurately assembled so that its upper edge is in proper relationship with the circumference of the roll 42 and can act as a doctor blade to prevent fibers that have adhered to the roll from being carried around the roll. In addition, the delivery bushing can be accurately assembled in the base 19 so that the lower end of the part 76 is located flush with the underside of the base as already referred to and will not snag into the sliver contacting the bottom of the base of the rotating head.

The delivery bushing formed of the

parts

75 and 76 is provided with an opening or passage therethrough of downwardly diverging taper, and having straight edges at its upper end. As already stated, the coiler head rotates in a counterclockwise direction and consequently the sliver will engage and be controlled by the trailing roll 42 so that it will properly enter the passage through the delivery bushing and engage with the trailing inclined side of the passage through the bushing so that the sliver will pass out of the delivery bushing at the proper location for accurate coiling thereof. In other Words, the sliver will engage the inclined left-hand side of the delivery bus'hing as viewed in Fig. 4- and said side Will constantly be exerting a counterclockwise coiling movement on the sliver.

It will be understood that as the gill box or other sliver forming apparatus is operating the sliver 11 passes from said apparatus through the trumpet 63 into the co-iler from whence it goes to the condensing bushing 68 of the rotating head of the coiler which has the elbowshaped passage tl'ierethrough. The sliver then passes from the vertical portion tidb of the elbow-shaped passage through the condensing bushing between the

rolls

42 and 45, it being recalled that the swinging roll 45 is the leading roll. Then the sliver passes into the upper end of the delivery bushing from which it. emerges to be coiled by the counterclockwise rotating head of the coiler into the clockwise rotating sliver can.
