CREEL FOR TEXTILE MACHINE Jack H. Selby, Twinshurg, Ohio, assignor to The Warner 8; svlz'lasey Company, Cleveland, Ohio, a corporation 0 '0 This invention relates to a creel for textile machines.

An object of the invention is to provide in a creel for textile machines a creel so constructed as to increase the stability of the creel even though the supporting surface for the creel may be somewhat uneven.

Another object is to provide a creel for textile machines wherein the frame is formed of separate frame sections which enables the frame to be adapted to the space available wherein it will be used as, for instance, in a small space, the frame can be a two-section frame while if a larger space is available and the capacity requirements for the creel necessitate it the frame can be made of a greater number of sections, and in addition, the frame being formed of separable sections facilitates the shipment of the creel.

Another object of the invention is to provide a creel for a textile machine wherein the rolls for supporting and feeding the slivers are of novel construction such that they positively move the slivers while each of the rolls can be positively driven at the correct feeding speeds.

A further object is to provide a creel wherein one of the rolls is positively driven from a drive source and said one roll positively drives the remaining rolls by novel operative interconnections therebetween which simplify the construction of the creel.

A still further object is to provide a creel as specified in the last named object and which creel is adapted to handle a double bank of slivers and includes a single roll driven from a drive source and acting through operative interconnections to drive the remaining rolls of the creel to effect driving operation of all the rolls for both banks of slivers.

Another object is to provide a creel having a frame made of separable sections with each section mounting feeding rolls in such position and in such spacing that when the sections are assembled together the rolls throughout the entire frame will be equally and properly spaced.

Another object is to provide in a creel for a textile machine an improved stop motion mechanism utilizing a light beam and which is so constructed that if the creel handles a single bank of slivers the light beam passes below the single web of slivers while if the creel handles a double bank of slivers the light beam will pass between the two spaced webs of slivers and then pass in the opposite direction below the lower web of slivers, whereby if a sliver in the upper web or in the lower web should break the light beam will be interrupted.

Another object is to provide in a creel for handling a double bank of slivers an improved arrangement of the feeding rolls such that selected slivers may pass over the next to the front roll of the uppermost series of.

rolls to be directed to the lower front roll to form the double bank of slivers.

A still further object is to provide a creel capable of handling a double bank of slivers and wherein the upper front roll is driven from a drive source and in addition to driving the other rolls in the upper series of rolls also United States Patent 2,885,742 Patented May 12,1959

drives the lower front roll for the lower bank of slivers while a freely vertically movable weight roll cooperates with the lower front roll and is rotated by the slivers being fed by the lower front roll and upon which slivers the weight roll rests.

Further and additional objects and advantages inherent in the invention and not hereinbefore specified will become apparent hereinafter during the detailed description of embodiments of the invention which is to follow and which embodiments are illustrated in the accompanying drawings forming a part of this specification and wherein,

Fig. 11 is a sectional view taken substantially on line 11-11 of Fig. 8 looking in the direction of the arrows and illustrates one of the reflecting mirrors of the stop motion mechanism shown in Fig. 10.

1 Referring to Fig. 1 which shows a creel embodying the invention, said creel is illustrated as used in conjunction with a gill box of the type having screw-actuated rectilinearly movable faller bars, said gill box being indicated generally at while the slivers pass throughthe gill box and emerge therefrom in the form of a single sliver which passes into a coiler indicated, at 16 that coils the sliver in a rotating sliver can 17.

The creel shown in Fig. 1 includes a frame beneath which are located a series of containers 18 for the slivers which are fed by the creel to the gill box 15 as will be well understood in the art. The creel frame is formed of separable sections, two of which are illustrated in Figs. 1, 2 and 3 inclusive as is the case when the shortest creel frame is used.

The rear section of the two section creel frame includes side bars 19 which may be channels and which at their rear ends are interconnected by a rear cross bar 20. The cross bar 20 has secured to it adjacent its opposite ends by suitable brackets 21 or other suitable securing means the two rear legs of the creel. Each rear leg includes an upper tubular part 22 which, for adjustment purposes, has threaded engagement in a lower tubular part 23 and the two threadedly interconnected tubular parts of each leg can be clamped or locked in adjusted position to vary the height of the creel frame above the supporting floor and to level the frame. The lower end of each leg part 23 mounts a flanged base 24 which can be secured to the floor.

The front frame section of the creel includes side bars 25 which may be channels and these bars are interconnected adjacent their front or forward. ends by a front cross bar 26. The adjacent ends of the side bars 19 of the rear frame section and the side bars 25 of the front frame section may be interconnected by plates interfitting the inside of the channels of both bars and secured together by nuts and bolts or other suitable means so that the two sections can be readily disassembled and separated.

If it is desired that the creel be increased in length then one or more intermediate sections can be secured between the rear and front sections as indicated in Fig. 2 with such intermediate sections including side bars 27 that can be removably interconnected with similar side bars 27 of another intermediate section or with the side bars 19 and 25 of the rear and front sections.

The front cross bar 26 midway of its opposite ends has secured to it the front leg of the creel. The front leg of the creel includes an upper part 28, the upper end of which is connected to the cross bar 26 by a bracket 29 while said upper part 28 isadjustably connected to a lower channel part 30 by means of a bolted connection, see Fig. 2. Consequently the upper and lower front leg parts 28 and 30 can be adjusted for different height creels and in conformity with the adjustment of the rear legs. The lower end of the lower part 30 of the front leg is provided with a flanged base 31 which can be secured to the floor. Brackets 32 are secured to. the front leg, and particularly to the upper part 28 thereof and to these brackets 32 a forwardly projecting channel bar 33 is secured which at its outer end is provided with a fitting for attaching it to the frame of the gill box 15.

It will be noted that the creel has a three-point sup-v port formed by the two rear legs and the single front leg and this arrangement provides for stability of the creel regardless of unevenness in the supporting surface on which the creel is mounted. Also due to the adjustability of the legs the creel frame can be readily leveled to compensate for supporting surface unevenness.

The side bars of each sectionof the creel frame; i.c., front, rear or intermediate section areprovided at predetermined intervals spaced longitudinally of the section with aligned openings which receive the threaded ends of cross rods 34, suitable nuts being mounted on the threaded ends of the cross rods 34 both inside of the side bars and exteriorly thereof to. tightly secure the rods to the side bars and to draw the side bars into proper parallel relationship to each other and also to stiffen each section.

Each side bar above each cross rod has secured to it an upwardly extending bearing bracket 35 which is provided with a vertical slot receiving the trunnions at the opposite ends of the rolls 36 of the creel. In Fig. 3 certain of the rolls 36 are omitted to show the rods 34 therebelow while other of the rolls 36 are broken off to show the rods 34 that are below said other rolls. The rolls 36 are provided with circumferentially spaced longitudinally extending flutes in the form of modified sprocket teeth 37 with the spaces between said teeth at the base of the latter of substantially rectangular cross section for a purpose later to be explained. The sprocket-like teeth 37 are so proportioned that the bottom of the teeth at the outer end of the substantially rectangular spacing between the teeth is the pitch circle of the sprocket while the teeth outwardly of such pitch circle constitute flutes on the rolls which engage the slivers to positively feed the same.

Each of the rolls 36 midway of its opposite ends is provided with an annular reces 38 extending inwardly from the outer ends of the teeth 37 substantially to the depth of the pitch circle. The front roll 36 of the creel i.c., the right-hand roll as viewed in Figs. 1, 2, 4, 9 and 10 and which is omitted in Fig. 3 to show the rod 34 therebelow, has fixed to it in the recess 38 a V-belt drive pulley 39, the hub of said pulley occupying approximately onehalf of the axial length of the recess 38.

A drive belt 40 extends around the front roll 36 and occupies the other half of the recess 38, and said drive belt 40 extends around the next roll toward the rear of the creel and occupies half of the recess 38 in said last mentioned roll. A similar drive belt 40a surrounds the last mentioned roll and occupies the other half of the annular recess 38 in said roll and extends to the next rearward roll around which it passes and occupies half of the recess 38 in said next roll. The succeeding rearward rolls are similarly driven by interconnecting belts 40b.

The drive belts 40, 40a and 40b as well as any belts for the rolls carried by an intermediate frame section are provided on their inner sides with spaced teeth 41 which cooperate with the substantially rectangular spaces between the teeth 37 of the rolls and below the pitch circle of said teeth 37. Consequently it will be seen that all of the rolls are positively driven from the front roll while the teeth 37 outwardly of the pitch circle form flutes which engage the slivers to positively move the latter in a feeding direction.

The pulley 39 on the front roll 36 is driven by a V-belt 42 that extends to a drive pulley 43 operated by a power driven part of the gill box 15. A suitable belt tightener idler 44 can be used to take up the slack of the belt 42.

A guard 45 suitably supported by the creel and gill box will enclose said V-belt 42 and the driven pulley 39 to prevent the slivers from catching in the pulley and belt. The cross rod 34 beneath the front roll 36 has clamped to it the U-shaped portions of two supporting brackets 46 extending transversely of the frame on each side of the V-pulley 39.

Each of the supporting brackets 46 has secured tothe free end of its upwardly and forwardly inclined arm a series of U-shaped sliver guides 47, there being as many of the guides 47 on the two brackets as there are slivers being handled by the creel in a single bank of slivers. The front cross rod 34 as well as the other cross rods 34 have U-shaped clamps 48 secured thereto by nuts screwed on eye rods '49, the eyes of which rods mount sliver guide bushings or eyelets 50.

It will be understood that one of the bushings 50 is mounted above each container 18 from which a sliver is drawn by the creel and that the sliver passes through said bushing. and over the adjacent roll to be one of the parallel slivers forming the sliver web. The bushings 50 will be arranged in predetermined order and correlated to the U-shaped sliver guides 47 and to the containers 18 in such manner that they will be staggered longitudinally and transversely of the frame and the slivers passing therethrough will form a web of parallel slivers.

It will be noted that the eyelet rods 49 can be adjustably clamped to the rods 34 in any desired position so as to vary the locations of the guide bushings 50 and thus produce a desired web of slivers. This adjustment of the eyelet rods 49 and bushings 50 facilitates the setup of the creel to meet varying conditions and provides a creel which is flexible in its adaptation to different conditions and expedites and facilitates the assembly of the creel.

It is contemplated that the following described stop motion is used in the single bank creel which has been described. The creel frame adjacent to the front roll 36 mounts on one side at a level below the web of slivers passing from the creel to the gill box a light producing means 51 of any suitable construction such that it projects a sharply defined light beam transversely of the creel below the web of slivers and focused on a photoelectric cell 52 or other light sensitive element that is secured to the frame of the creel directly opposite to the means 51 (see Figs. 3 and It will be understood that the light sensitive element 52 is operatively associated with electrical control circuits such that when the light beam is interrupted by a sliver intercepting the same as would occur should a sliver break, that then the power drive to the gill box and creel is automatically stopped.

Fig. 7 illustrates schematically a creel embodying the invention and adapted for handling a double bank of slivers. In this arrangement of Fig. 7 it will be noted that certain slivers S of the web passing over the rolls 36 when reaching the next to the front roll can pass downwardly to a lower front roll 53 located below the upper front roll and fluted similarly to the upper rolls but Without the annular recess 38 of the upper rolls as it is driven in a different manner. The slivers which pass over the lower front roll 53 are held against the flutes of said lower roll by weight rolls 54 mounted on axes which are vertically displaceable, it being noted that two such weight rolls 54 are provided with the inner trunnions of said rolls being supported in vertical slots formed in brackets 55 secured to the front leg. The outer trunnions of said weight rolls 54 are supported in vertically slotted blocks 56 secured to the inner sides of vertically depending plates 57, the upper ends of which are interconnected to the side bars 25 of the front frame section by means of spacer blocks 58.

Interconnected between the upper portion 28 of the front leg and each of the plates 57 is a cross rod 59 that has secured to it a suitable number of U-clamps 48 mounting eye rods 49 that support sliver guide bushings 50. It will be noted that the eye rods 49 are downwardly extending so that the bushings 50 carried thereby are properly correlated to the lower front roll 53. A supporting tie rod 60 extends between the plates 57 and the said tie rod 60 has secured to it depending bracket arms 61, the lower ends of which are secured to a bar 62 extending transversely of the frame. The bar 62 has secured to it at predetermined locations downwardly extending U-shaped sliver guides 47 already described in connection with the single bank creel.

The lower front roll 53 has its trunnion at one end of the roll supported in a bearing block secured to the inner side of the plate 57, while the trunnion at the opposite end of the roll is extended so as to pass through a bearing block 63 carried by the other plate 57. The extended trunnion at the opposite end of the roll 53 has secured to it a V-belt pulley 64 and said pulley 64 may be formed of two separable parts to facilitate assembly or adjustment.

The upper front roll 36 has one of its end trunnions extended as clearly indicated in Fig. 9 to pass through a bearing block 65 secured to the outerside of the plate 57 at the upper end of the latter. The'extended trunnion of the upper front roll 36 has fixed to it a V- belt pulley 66 which is operatively aligned with vthe pulley 64 so that a V-belt 67 can pass around the pulleys 66, 64 wherefore the lower front roll 53 will be driven at a one-to-one ratio by the upper front roll 36.

The plate 57 at the side of the creel having the pulleys 64, 66 pivotally mounts a rocking arm 68 which is provided with an arcuate slot 69 through which passes a clamping screw carried by the plate 57 and which screw carries a clamping nut 70. It will thus be seen that the arm 68 can be moved to various positions and locked therein. The arm 68 mounts a belttightening idler pulley 71 which functions to take up any slack in the V- belt 67. A guard or cover 72 is provided to enclose the pulleys 66, 64 and belt 67.

The light beam projecting means 51 alreadyv referred to with respect to the single bank creel can besecured to one of the plates 57, Le, the right-hand plate as shown in Fig. 10, while the light responsive means 52 in the form of a photo-electric cell can also be secured to the same plate 57 above the means 51. The other plate 57 may have secured to its inner side suitable vertically spaced reflecting mirrors 73 arranged in inverted order with respect to each other so that the light beam emitted from the means 51 will strike the lower of the mirrors 73, be reflected at right angles therefrom upwardly to the upper mirror 73 and from which it is reflected at right angles to the photoelectric cell 52.

It will be noted that the horizontal reaches of the light beam are parallel with the upper reach of the beam passing below the upper web of slivers while the lower horizontal reach of the beam passes below the lower web of slivers. Consequently a single light source and a single light responsive means can be employed in the stop motion mechanism for the double bank of slivers since if a sliver in the upper bank or a sliver in the lower bank should break the light beam from the light source to the photoelectric cell would be interrupted.

It will be noted by reference to Fig. 7 that where the creel is adapted for a double bank of slivers a spraying device 74 may be located between the upper and lower webs of slivers intermediate the creel and the gill box and in a position to spray fluid material into the V formed by the converging webs of slivers as they enter the feeding rolls of the gill box. This enables lubricating or other material to be put on the slivers on the inner sides thereof and confined between the slivers of the convergent webs.

In review it will be recalled that the sliver frame being formed of separable front, rear and intermediate sections can be adapted as to capacity and size to suit various requirements and also the separable frame sections facilitates shipment of the creel. In addition, it will be recalled that the creel is supported by two rear legs and one front leg forming a three-point suspension which provides for greater stability of the creel frame. The supporting legs can be adjusted so that the creel can be located at various heights and leveled horizontally.

Also it will be recalled that the guide bushings for the slivers can be adjustably positioned and readily assembled on the creel frame as can also the brackets 46 and sliver guides 47, thus increasing the adaptability of the creel and facilitating the setup or assembly thereof. Furthermore, it will be recalled that the fluted rolls provide a positive drive for moving the slivers along the frame and toward the gill box while the drive to the rolls is derived from the front roll by means of in terconnecting driving belts which enable part of the fluted grooves of the rolls to be used as sprocket-like driving pulleys for the rolls.

In addition it will have been noted that a creel embodying the invention can be readily adapted for either a single bank. of slivers or a double bank thereof when it is. desired to increase the capacity of the creel. Also the stop mechanism is such that a single light beam source and a single light responsive means can be employed for either a single bank of slivers or a double bank thereof and that. the light beam will pass below the single web of slivers or below both the upper and .lower webs of slivers so that any sliver which breaks will interrupt the light beam and stop the operation of the gill box and creel.

Although preferred embodiments of the invention have been. illustrated and described herein it will be understood that the invention is susceptible of various modifications and adaptations within the scope of the appended claims.
