amt o. Blom, Springfield, Mass, assignor t Bigelow-Sanford Carpet U0. Inc, Thompson j I .ville, Conn. a corporation of Massachusetts Application October 21, 1935, Serial No. .5.8 8 31 01am; (01. 28-555).

This invention relates to setting or winding frames employed for winding yarn on spools to be used in the weaving of Axrriinster rugs, and it particularly pertains to improvements in the construction of machines of that character whereby to obtain a more uniform and more accurately measured winding of the yarn on the spools thanhas. been obtainable heretofore.

In the winding of spools on such frames it is essential that substantially the same predetermined amount of yarnv be wound on all of the spools," both overwound and underwound, and I have foundthat that result can he accom-.

plished by providing a tension on the yarn adjacent the spool .as it is being wound which is not only ofitpproxirnaizely the same predetermined amount for all spools being wound, both overwound and underwound, but which is also substantially unvarying as the spools fill with yarn.. The preferred'form of apparatus and method embodying my invention insures the proper substantially unvarying tension around the spool by positioning the threewinding rolls at substantially equal distances around the. pee

" riphery of the spool, whic rolls are yieldingly pressed thereagainst and are rotated at a predetermined differential, in speed to exert a drag on the yarn at the points of contact there with. .Ifhe predetermined amount of tension which is thereby. produced is preserved as the spool fillsby maintaining thesubstantially equidistant relationship of the spools while permitting a gradual yielding divergence of the rolls as required to accommodate-the growth of yarn on "the spool.

The foregoing characteristics of my apparatus are preserved for bothoverwindingand under- Winding and in that manner I insure an equal.

amount of tension and hence a uniformity in the amount of yarn wound in either direction.

Accuracy of measurement of the yarn Wound. on the spool is not dependent solely upon the accuracy of the Winding operation of the setting frame, but also depends upon the manual operations'oi drawing off the yarn at the completion of the winding of one spool, clamping up the ends of the yarn strands on the wound spool,v and overlapping the severed ends ofyarn around Here tof ore, inaccuracies have arisen through the failthe next succeeding spool to he wound.

By way of introduction to the description of the preferred embodiment of my invention, reference is made to Figs. 1-6 inclusive wherein I have diagrammatically illustrated the disposition and mode of operation of the winding rolls of one embodimentof my invention.

As indicated diagrammatically in Fig. l, the yarn l is fed, asis customary, from the bobbins 2 comprising the creel 3, through a combing reed 4 to a pair of idler rolls 5 and 6 which are associated with counting mechanism for-measuring the yarn and which also produce a certain tension on the yarn as it passes through a second reed H], over an idler roll I! and thence to the spool 52 on which it is being wound. Movement of the yarn from the creel 3 through the aforesaid mechanism and to the spool i2 is effected by three winding rolls 20, 2| and 22 which are disposed in peripheral engagement with the spool l2 and the yarn wound thereon.

As indicated in Fig. 2, wherein is shown the position of the winding rolls 20, 2| and 22 at the beginning of the winding operation, the rolls are then disposed at equal intervals around the periphery of the spool |2. As the spool l2 fills with yarn, I preserve the equidistant relationship of the rolls while permitting'divergence of the rolls to accommodate the growth of yarn, until the end of the winding operation when the rolls are positioned as illustrated at 20B, 29B and 22B of Fig. '3. To preserve this equidistant relationship at all stages of the winding, I may mount the winding rolls each in sliding bearings extending radially from the axis of the spool l2, but I have found that for simplicity of construction, one of the rolls, such for example as roll 2|, may be mounted in stationary bearings and the rolls 20 and 22 may be mounted in bearings carried by crank arms which are pivoted to the frame of the machine and are adapted to swing in arcs about their pivots to accommodate the growth of yarn on the spool. This construction I have diagram matically illustrated in Fig. 4 wherein the roll 20 is indicated as mounted in a bearing which swings about the point 20' as a pivot and the roll 22 is mounted ina hearing which swings about the pivot 22'. The disposition of the pivots 20' and 22' and the lengthof the radii to the axes of the rolls Ziland 22 can readily be chosen to provide the equidistant relationship of the rolls 20 and 22 relative to each other andto the stationary roll 2| during the entire winding operation, including the intermediate positions of the rolls 2|] and 22 and I have found that in a machine constructed on that principle, the axis of the spool l2 may move away from the stationary spool 2| during I the winding operation in a path which describes an are, as indicated at 32. I

To provide access to the spool |2 for its removal at the completion of the winding operation and for'insertion of a new spool, the upper roll 22 is adapted to be swung further about the pivot 22 to the position indicated diagrammatically at 22C.

As stated above, I have found that the proper tension of the yarn directly at the periphery of the spool I2 on which it is being wound may be effected by a differential of speeds between the three equally spaced winding rolls in engagement with the yarn, whereby to exert a drag on the yarn at the points of contact of the winding rolls. As indicated diagrammatically in Fig. 5, wherein I have shown, by arrows, the direction of rotation of the rolls 20, 2| and 22 for the overwinding operation, I provide this differential of speed and resultant frictional drag on the yarn by making the roll 22, which is the initial roll with which the yarn comes in contact as it enters the spool, and idle roll, and by making the rolls 20 and 2| driven rolls with the roll 2| rotated'at slightly greater peripheral speed than that of. the roll 20. To insure equality in the amount of yarn wound in the underwound and overwound directions of rotation, I preserve this same relationship for the underwinding, whereby, when the direction of rotation of the rolls is reversed, as indicated by arrows in Fig. 6, the roll 2| with which the yarn initially comes into engagement is an idle roll and the rolls 20 and 22 are driven rolls with the roll 22 rotating at a speed which is slightly greater than that of the roll 20.

Referring now to Figs. 7 and 8 I will describe first the general assembly of my novel setting frame. As there indicated, the creel 3 is supported at the proper elevationat what I shall designate as the rear of the setting frame. The

frame of the setting frame has the two vertically extending side members 50 and 5| in-which are mounted the winding rolls 20, 2| and 22 in a manner to be described more in detail hereafter. An

electric motor 52 or other suitable power source 7 is provided for driving the winding rolls in either their overwinding or underwinding directions of winding rolls is also adapted to move the winding rolls 22 from its winding position to its open position indicated at 22C to provide access for removal of the spool |2 which has been wound and insertion of a new spool in winding position.

The side frame members 50 and 5| also rotatably support the measuring rolls 5 and 6, the bottom roll 6 being fixed in positionand the top roll 5 being mounted in movable bearings 600 which may be elevated or lowered in the side slots 55 in the frame members 50 and 5|.

To describe first the mountings of the rolls 20 and 22 whereby they may be moved toward and away from the spool |2the winding roll 22 (Figs. 9 and 11) is carried on the shaft 80 which is mounted at both ends in bearings carried by pivoted housings El and 82 rotatably mounted in the side frame members 50 and 5|. The details of these mounting elements are illustrated in Fig.

12 in which are shown the bearings 83. and 84 carrying the ends of shaft 80 and in turn carried by the pivoted housings BI and 82 respectively. Both housings are constructed in the general form of a crank, the housing 8| having a vertically rising crank arm portion 90 integral with and extending from a hub 92 journalled in the frame 50 of the machine. The hub 92 is reduced in cross-section at 93 to receive a gear 94 .fixed to As will appear, the

to, I

the hub 92 bymeans of the dowel 95 and screw 96 passing through aligned holes in the gear 94 and hub 92. A similar crank housing to be described, is provided for the bearing 84 on the opposite end of shaft 89 and it is apparent that as a result of this construction, rotation of the gear 94 rotates the hub 92, thereby rotating the crank arm 90 of the housing 8! and swinging the roll 22 about the axis of hub 92.

The gear 9-; is one element in a train of gears which I shall refer to as the pressure gears, rotated pneumatically by a piston in cylinder. H3 (Fig. 8) whereby a yielding pressure of the driving roll 22 (and, as will appear, also the driving roll 253 against the spool) is effected.

Referring now to Figs. 9 and 12, the aforesaid pressure gear 94 meshes with idler gear I05, rotatably mounted on the stud shaft I06 fixed in the frame member 58. The gear I meshes with the gear 98 which is rotatably mounted on the shaft 59 (Fig, 13) and in turn meshes with the gear segment 99 keyed to the shaft NH.

The shaft IilI, as indicated in Figs. 8 and 11,

extends across the machine and has bearings in side frames 55) and 5|. Intermediate its length the shaft II] I, carries rigidly fixed to it the pinion 'I I6 which meshes with the rackIII carried by the plunger IIZ which is pneumaticallyelevated and depressed in the cylinder H3 in a manner to be described more in detail hereinafter. v

The shaft IIiI carries rigidly secured to its extremity opposite to that carrying the gear segment 98 and adjacent the frame 5| of the machine, (Fig. 11) a second segment IZll identical with the segment 99. The segment I253 is connected, through a second set of pressure gears mounted adjacent the frame 5I of the machine,

to crank housings carrying the opposite ends ofment i253 are illustrated in Fig. of the drawings and as there shown, the segment .IZil fixed to shaft Elli meshes with the gear I2I secured to a hub I22 of a crank housingcarrying the shaft of the roll in a manner to be described hereinafter. The gear I2I mieshes with an idler I23 rotatably mounted on the stud shaft I2- l projecting from the frame SI of the machine (see also Fig. 12). gear 525 which, as indicated in Fig. .12, is fixed, by means of the dowel and screw l2! and I28, on the hub 53 3 suitablyjournalled in the frame El and integral with the crank housing 82 carrying the bearing 84 for the right hand end of the shaft 8%. i

The trains of pressure gears on both sides of the machine have corresponding gears of'equal pitch diameters and number of teeth and, it will be apparent from the above description that elevation and depression of the plunger I52 in the cylinder IIf-l will move the roll 22 in either a clockwise or counter-clockwise direction, as viewed from either side, dependingupon whether the plunger II2is elevatedor depressed and will apply an equal amount of pressure from both ends of the roll, pressing it yieldingly against the spool I2. u

To describe now the pressure gears which swing the bearings of the roll 28, that roll is carried. by a shaft t il} (Fig. 13) which has the bearing I in the arm I 52 of a crank housing, the hub I43 I of which is journalled in the. framememberfill of The idler I23 meshes in turn with the the'machine, and carries the aforesaid pressure gear 98. The pressure gear 98 isnot fixed to the hub I43 as was the corresponding gear 93 associated with the roll 22, but carries a pin I5I, the enlarged end I 52 of which has. a sliding fit in the slot I 53 of the hub I43, which slot, as indicated in The gear til is connected, as described above, with the gear segment 99 (Fig. 9) fixed on the pneumatically rotated shaft NH. 1 On the opposite side of the roll 20, from that just described, the shaft ltd has a bearing I60 inthe crank housing IGI whichhas a hub I22 iournalled in the frame iii of the machine, which hub carries the gear Ilil. The gear I2I is. connected to the hub I22 by a pin I63 having a head Ifie working in an arcuate slot I65 identical in construction and function with the arcuate slot I558 in the hub I63 on the opposite side of the machine. The gear 52!, as statedabove, meshes with the segment 520 (Fig. 10) which is fixed to the end of pneumatically rotated shaft I0 I.

Referring now to Fig. 11, rotation of shaft IBI is effected by means of pinion IIO fixed to shaft illl and meshing with rack I I I carried by piston red I it elevated and depressed by a double acting piston QIi'iil sliding in the cylinder H3. cates a threeway valve adapted selectively to elevate or depress the piston 230 pneumatically or to assume a release position in which the piston 239 can be elevated or depressed at will whereby the rolls 2i} and 22 can be manually swung about their pivots.

The valve 2!): communicates at 202 with a sup- 1 2M indiof the cylinder I I3, above the piston 2M, and the pipe 206 leading to the port 20] brings the valve into communication with the lower part. of the cylinder I I3 below the piston 290. It will be noted that the ports 2&5 and 297 are diametrically op-' posite each other on a diameter which is perpendicular to the diameter along which the ports 292. and. 263are in alignment. The valve 25)! is fitted with a suitable hand lever, not shown, whereby it may assume the three positions indicated in Figs. 11, 1'7 and 18.

The valve 2M is drilled to provide a conduit 2m extending diametrically across the valve 2M, which conduit, when disposed in the positionindicated in 11, brings the upper and. lower ends of the cylinder I it into communication with each other whereby the piston Bibi! may beelevated or depressed at will and the rolls 20 and 22 may be manually swung about their pivots.

The valve 20% is also drilled to provide two vide an angular conduit 2I3, each end of which I is disposed at a distance of around the circumference of the valve EIII from the nearest em of conduit 210.

The valve which is constructed as above described, if rotated to the position indicated in Fig. 1'7, disposes the connecting conduits 2H and 2I2 in position to bring the port 292 into communication with the port 20'! whereby compressed air entering the port 202 will be conducted through the pipe 296 tothe lower end of the cylinder II3, thereby elevating the piston 200. At the same time the upper end of the cylinder H3, above the piston 29!], is in communication with the .exhaust pipe 293 as a result of the position assumed by the conduit 2|3 which brings the port 295 into communication with the exhaust port 293. This elevation of the piston H2 will cause clockwise rotation of the segment 39, as indicated by the arrow in 9, which will cause counter-clockwise rotation of the gear 98 which meshes with the segment 99. This counter-clockwiserotation of the gear 98 will cause the end I52 of pin l5| carried by the gear 98 (Fig. 16) to abut the end I54 of the slot I53 in the hub I43 to swing roll 20 to its position indicated in Fig. 16. The roll 22 (Fig. 9) will also swing in a counter-clockwise direction about the axis of the shaft I00 as a result of gear train 98, I95 and 94. It will be observed that this direction of swing of the rolls 29 and 22 urges those rolls into engagement with the spool I2. This is the running position of the rolls 29 and 22 for winding yarn on spool I2 and it will be noted that as the spool I2 fills with yarn the rolls 26 and 22, which yieldingly press against the spool, are swung away from. eachother while maintaining their equidistant spacing about the periphery of the spool (Fig. 4). This swinging movement causes a gradual lowering of piston 200 against the pressure in cylinder H3.

After the spool I2 has been wound, it is desirable, as stated above, to swing the top roll 22v away from the spool I2 and to the position indicated. at 22C in Figs. 4 and 9, whereby to permit removal of thewound spool and insertion of an empty spool.

To effect this movement the valve 29! is now shifted to the position illustrated in Fig. 18 and in that position the port 292 communicating with the compressed air supply is brought into communication with the port 205 and thence to the upper end of the cylinder H3 at the same time that the lower end of the cylinder is exhausted through the port 201 now in communication with the port 293 through the valve conduit 2I3. The resultant depression of the piston 290 causes a counter-clockwise rotation of the gear segment 99 in the direction opposite to that indicated by the arrow in Fig. 9 which causes a clockwise rotation of the gear 98.

This rotation of the gear 98 (Fig. 16) moves the pin end I52 in a clockwise direction and as a result of the weight of roll 20, the end I54 of the slot follows the pin end I52 until the roll 20 comes to rest against a convenient stop IlIB, after which swinging of roll 2!] stops, while permitting the gear 98 to, rotate approximately one-quarter revolution in a clockwise direction. This amount of rotation of the gear 98 is sufiicient, however, to rotate gear 94 in a clockwise direction in an amount sufficient toretract roll 22 to its 220 position, thereby providing the desired access to the spool I2.

The rolls 2!], 2| and 22 are each power-driven by certain mechanism now to be described. It

will be recalled that the rolls are tobe rotated in one direction for overwinding spools and in the opposite direction for underwinding spools and that in the overwound direction (Fig. 5) the roll 22 is, in my preferred embodiment, an idler roll and the rolls 2B and 2| are driven at different relative speeds, whereas in the underwound direction (Fig. 6) the roll 2| is an idler and the rolls 2!! and 22 are driven in a direction opposite to that for the overwinding and at the same speeds as the rolls 2B and 2| respectively were driven in the overwinding direction. These rolls are driven from a motor 52 (Fig. 7) which has reversibleconnections later to be described.

As indicated in Fig. 11, the motor 52 has an elongated shaft 63 which includes clutch 64, on the end of which shaft the pinion 10 is rigidly mounted. The pinion 10, which is the initial gear in a train of gears which I shall refer to as the power gears, meshes with an idler 65 (see also Fig. 9) fixed to the stud shaft 66 rotatably mounted in a suitable bearing in the frame member Stud shaft 66 also carries rigidly fixed to it pinion 61 which meshes with a gear 68 fixed on the aforesaid shaft 69 in front of the gear 98 (see also Fig. 13). The gear 68 meshes with the gear 72 which is connected to the shaft 69 with which the roll 2| is integral, by means of a oneway clutch illustrated in Figs. 14 and 15.

The shaft 6|! carries fixed to it at the end seen in Figs. 9 and 14, an annular cap member 3|] which has a hub 3| keyed at 32 to the shaft 60. The hub 3| carries loosely mounted thereon the aforesaid gear 12, which has a hub 12A loosely mounted on hub 3|, which gear carries fixed to it, by means of suitable dowels or bolts 38, the slotted disc 33, which, upon rotation of the gear I2, may rotate freely within the annular member 3|]. The disc 33 is one of two elements of a one-way clutch of usual construction and has the tapered slots 34 (Fig. 14) which receive cylindrical rollers 35 whereby rotation of the gear I2 and disc 33 in a counter-clockwise direction, as viewed in Fig. 14, imparts counter-clockwise rotation to the annular member 30 and shaft 69 to which it is' fixed, thereby rotating roll 2|. When the motor is reversed to rotate gear 12 in the opposite direction, that is clockwise 'as viewed in Fig. 14, the rollers 35 will be driven to the enlarged ends of their slots and roll 2| may then rotate as an idler in the same direction as the gear 72 is then being driven and at any speed which does not exceed the rotational speed of gear 12.

The gear 68 which drives gear 12, is fixed to the shaft 69 as indicated by the spline 40' in Fig. 13. The shaft 69 has also fixed to it the gear 4| meshing with the gear 42 enclosed in the swinging arm I42 of the housing carrying the bearing I 4|, which gear 42 is fixed to the end of the shaft I49 with which the roll 29 is integral. Thus rotation of the gear 68 imparts rotation to the shaft 69 and gear 4| which rotates the gear 42 and drives the roll 20. The roll 20 is adapted, as above described, to be swung gradually away from the axis of spool I2 during the winding, but as this swinging movement is about the axis of the shaft 69 on which drive gear 4| is mounted, the gears 4| and 42 will always remain in mesh at any position of the roll 20 about the axis of the shaft 69. It will be noted that no clutch mechanism is included in the drive for roll 20. This roll is accordingly power-driven at the same rate of speed but in opposite directions for overwind and underwind.

The roll 22 is power-driven from the gear 68 (Fig. 14) through the idler gear 43 rotatably mounted on the shaft I06 infront of the aforesaid pressure gear. I05 (see also Figs. 9 and 12).

The gear 43 meshes with the gear 44 which is rotatably mounted on shaft I in front of the pressure gear 94 and is adapted to rotate the shaft Hit] by a one-way clutch mechanism. The gear 44 is connected by means of the dowel 45 and screw 46 to a. slotted disc 4'! which, as indi-' cated in Fig. 14, has four tapered slots 48 each receiving a roller bearing 49. Surrounding the slotted disc 4'! is the annular cap member 225 which has a, hub 226 splined at 22! to the shaft I00, on which hub 226 the aforesaid gear 44 is rotatably mounted. The opposite end of the shaft Hill carries fixed to it the gear 228 which meshes with the gear 229 secured to the end of the shaft 80 carrying the roll 22.

By this mechanism rotation of the gear 44 and disc 4'! in a counter-clockwise direction, as viewed in Fig. 14, imparts rotation to the shaft Hi5 and, through the gears 228 and 229, to the roll 22 in a clockwise direction. Idle rotation of the roll 22 in a counter-clockwise direction is permitted by its one-wayclutch mechanism when the motor is reversed and gear 44 is driven clockwise.

As stated above, my setting frame includes measuring apparatus which has associated with it means for providing a predetermined limited. amount'of take-off which is available to the operative for the purpose of clamping up the spool after it has been wound and for giving the initial wrap for the next succeeding empty spool.

Referring now to Figs. '7 and 10, the measuring rolls 5 and 6, through which the yarn passes from the creel 3 to the spool !2, are yieldingly pressed toward each other and are rotated by the passage of yarn between the bite of the rolls. Either or both of these rolls may be provided with suitable friction elements of the type commonly provided on such rolls for producing a drag on the yarn and thereby tensioning the same duringthe winding. The axis of the lower roll 6 is fixed in position and the upper roll 5 is movable toward and away from the roll 6 and is spring-pressed in yielding engagement therewith during the winding operation. The upper roll 5 is carried by bearings 600 which are slidably mounted in the parallel slots 55 provided in the frame members 50 and 5! on each side of the machine (see Figs. Band 10) The bearings are spring-pressed in a downward direction by means of a spring 60! disposed betweena member 688a member-600a, around which pin the spring 60! is disposed. The pin 563 has an enlarged head (H2 against which the extremity 602 of the arm 6135. abuts at times to elevate the bearing 69!).

The arm. 605 forms one member o'f a toggle, the other arm 60! of which is pivoted at M3 to the arm 5B5and is secured to a shaft 608 which extends across the machine and which, as indicated in Fig. 8, has hearings in both side frame members 5B and 5!. provided at the other end of roll 5 and the extremities of shaft 608 have secured to them the hand levers 609. If desired the shaft 608 may be a up counterweighted as indicated at 6 l0.

Both of the toggle joints 6!.3 have the usual stops against which the joints abut when the toggle elementsa're straightened past alignment with eachother and in my preferred embodiment .fixed to the shaft 228.

The same toggle construction is It is apparent that rotation'of the hand lever 609 in a counter-clockwise direction, as viewed in Fig. 7, breaks the toggle joint M3 and raises the extremity 592 of the arm 605 against the en- I larged head 6H2 of the pin 523 connected to the member Ellilmthereby raising the same and elevating themeasuring roll 5. When the parts are returned to the position indicated, by straightening the toggle joint,. the spring-pressed button M5 is held inwardly to close the contact in the.

switch GIS and in this position it will be noted that the measuring roll 51s yieldingly urged in peripheral engagement with the fixed measuring roll 5. i

As indicated in Fig. 10, the roll 6 carries fixed to its shaft a pinion 225 meshing with an idler gear 223 which in turn mesheswith a gear 22! The gear 22'! meshes with a so-called measuring gear 229 fixed to the rotatabie shaft 230 to which shaft is also rigidly secured the gear 23!. The gear 23! meshes with the gear 232 which in turn meshes with the gear 233. By this train of gears, feeding of the yarn through the measuring rolls 5 and 5 by means of the windingrolls 2i), 2! and. 22 causes rotation of the gears 232 and 233 in the direction indicated by arrows and thesegears form two of the elements of'a so-called hunting tooth mechanism which I employ to trip a limit switch after a predetermined amount of yarn has been wound.

The hunting tooth apparatus is constructed as follows: The face of gear 232 carries fixed to it the cam 235, (Fig. 20) having a fiat cam portion I 249, on which cam the lever 24!, pivoted at 222 is adapted to ride. The lever 24! has a reduced flange portion 236. forming a squared shoulder struction the extension 2553 of the lever may be swung in a counter-clockwise direction about the pivot 25! but cannot move in a clockwise direction beyond a position in alignment with the lever 24!.

Extending downwardly from the extension 250 adjacent the pivot 25! is a tooth 24'! adapted at times to be received by the notch 246 on a disc 245, suitably secured to the face of the gear 233 and adapted to rotate therewith. The other From the above description it is apparent that when the gears 232 and 233 assume the positions indicated in Fig. 20, whereinj'the fiat portionZMl on the cam 235 is uppermost, the lever 24! will be disposed in a substantially horizontal position,

thereby permitting the tooth 241 to drop into the notch 246 when the notch arrives at the position of Fig. 20 The momentum of the notched disc 245, travelling in the clockwise direction indicated by .the arrow, will force theside'walls of the notch 246 against the tooth 24'! to rotate the extension 25!] slightly about its pivot 25! to lift the chain 252 and actuate the limit switch 253.

This operation will occur only when the rotation of gears 232 and 233 bringsthe fiat portion 245 of cam 235 and the notch of disc 245 uppermost at the same time and the gears .232 and 233 each i have a different but predetermined odd number of teeth so that this position of the cam and notched disc willbe assumed only once during a predetermined multiple of rotations of the, gears limit the counter-clockwise throw thereof.

232 and 233.

The ratio of the teeth in the gears 232 and 233 e are correlated with the gear ratios in the gear "train leading from the gears 232 and 233 to the measuring rolls and 6 to trip the limit switch 253 upon the passage of a predetermined yardage of yarn through the measuring rolls 5 and 6.

For the purpose of making the length of yarn measured by the hunting tooth apparatus, ad-

justable by lengths of one foot, I make the measuring roll 6 precisely one foot in circumference and I so design the gear ratios that a change of one tooth in one of the gears corresponds to a change of one revolution of the measuring roll 6, that is, a change in one foot of yarn measured. To that end the ratios of gears 225 and 221 is made one to three and the ratios of gears 229, 23!, 232 and 233 is such that the number of teeth in the measuring gear 229 determines the yardage of yarn measured, each tooth representing one foot of yarn, so that by replacing the gear 229 with one having, for example, one more tooth than the gear 229 shown in the drawings, the yarn measured will be increased by one foot.

For the purpose of permitting the draw-off of only a predetermined amount of yarn, the hand lever 260 is provided. This lever is freely pivoted on the shaft 228 and carries with it a disc 26! having a cam roller 262 (see also Fig. 20)

adapted to abut against and raise the roller 263 surrounding the pivot 25! joining the levers 24! and 250 upon counter-clockwise rotation of the disc 26!,

Between the disc 26! and the gear 221, both mounted on the shaft 228, are two ratchets (see .Fig. 19) indicated at 265 and 266, secured to shaft 228. Engaging the ratchets 265 and 266 is the double ended pawl 210, the end 210A 01 Q which lies in the plane of the ratchet 266 (see .also Fig. a) and is adapted to engage therewith and the end 2103 of'which lies in the plane of, and is adapted to engage, the other ratchet 265. The pawl 210 is fixed .to a pivot 21! extending from disc 26! to which pivot is also fixed an arm 212 connected by the link 213 to the hand lever 214 pivotally mounted on the upper end of the lever 260. The link 213 is spring-pressed downwardly as by the spring indicated at 215 so that the normal position of the pawl 210 is such that the end 210A engages the'teeth of the ratchet 266 and it is apparent that with the pawl 210 inthat position, counter-clockwise rotation of the hand lever 260 will rotate the shaft 228 and gear 221 which is fixed to it, thereby rotating gear 226 and the measuring rolls 5 and 6 in a direction to feed yarn from the creel toward the spool. Such rotation is permitted as a result of the engagement of the roller 262, carried by the disc 26! (see also Fig. with the roller 263 surrounding pivot joining the levers 24! and .250, thereby elevating the pivot 25! and lifting the wound spool and providing the overlap to commence the winding of the next succeeding spool. Upon retraction of the lever 260 against its stop 216 a second tooth of the ratchet 266 will be in position to be engaged by the end 210A of the pawl and upon a second counter-clockwise rotation of the lever 260 the second half of the desired amount of yarn will be unwound. The lever 260 is then returned against the stop 216 but as I wish to provide that only a predetermined amount of yarn, measured by two throws of the lever 260 can be unwound by the oper- I ative, I provide that a thirdthrow of the lever 260 will be ineffectual to unwind more yarn by providing that at the beginning of this throw there will be no tooth in the ratchet 266 in position to be engaged by the end 210A of the paw! 210. Thus it is apparent that a pair of teeth only are positioned to be engaged by the pawl 210 during any givenunwinding operation.

As stated aboveythe gear train leading from the measuring rolls 5 and 6 to the hunting tooth apparatus mounted on the gears 232 and 233 by which the machine is automatically stopped, is adapted to be changed by replacement of the measuring gear 229 to vary, in foot lengths, the amount of yarn measured by the rolls 5 and 6. It is apparent that if the measuring gear 229 is so changed by the substitution of a gear of, say, one tooth more, the gear 221 carrying the ratchet 266, upon being stopped automatically, will come to rest in a position different from that illustrated and one in which the pair of teeth which would have been engaged by the end 210A of the pawl 210 prior to the change would no longer be in the proper position for the manual unwinding.

As stated above, I provide that the ratio between the number of teeth of the gears 225 and 221 is in the proportion of one to three and a change of one tooth in the measuring gear 23! corresponds to change of one revolution of gear 225 or one-third of a revolution of the gear 221. Accordingly, I provide the ratchet 266 with three pairs of teeth (see Fig. 10b) each pair spaced equidistantly from each other around the ratchet 266, and it is apparent that one of these pairs of teeth will be in positionxfor engagement by the end 210A of thepawl 210, regardless of the change in teeth in the measuring gear 229.

It is sometimes desirable to be able to rotate th measuring rolls 5 and 6 in a direction to I unwind the yarn from the spool and in the direction of the creel, such as when the yarn has become tangled about the spool. For that purpose'the second ratchet 265 is provided with evenly spaced teeth designed to be engaged by the end 210B of the pawl 210 when that end of by the lever 260.

Referring now to Fig. 21, I will describe the electric circuits connecting the driving motor 52 with the limit switch 253 and with'other switches used to start and stop the motor 52 manually and automatically.

The numerals 40!, 402-and 403 indicate power mains leading from a'suitable source of three phase sixty cycle current at 550 volts. These threev phase leads are connected to a self-maintaining magnetic switch400 and thence to a reversing switch 404 from which the leads pass to the motor 52. M0 indicates diagrammatically a brake adapted to stop the rotation of the shaft of the motor 52, which brake is normally maineueasse tained in applied position but is moved to released position by the solenoid 4I2 connected by leads M3 and 454 to power mains 402 and 40! respec lead 4532 through the lead M1 and is connected by the lead 4H5, throughclosed switch BIB, to the terminal 42iiengaged'by the armature 42! of relay 422 which is normally maintained in closed position across terminals 42! and 423 to complete the circuit from the lead 4!8 through to'the lead 424. connected to one pole of the aforesaid limit switch 253. The limit switch is in series with momentary contact switch 430 by means of lead 43! connecting the limit switch to terminal 432 of the switch. The pivoted switch arm 434 is normally spring-pressed to closed position against the contact 432 and the switch arm 434 is connected by the 1ead436 to the terminal 431 disposed adjacent a switch bar 438 mounted on bar 4H5, which closes circuit between the terminal 431 and a terminal 439 connested by wire 443 to lead 433. v t

The aforesaid lead .436 is also connected to a switch 442 normally spring-pressed to open position, as indicated, but adapted to be closed across the terminal 443 which, by the lead 444 is connected in circuit'with the'power main 433.

With the device wired as above described, a momentary closing of the starting lever 442 closes the circuit from the wire 444 which, as above indicated, is connected to the power main 403,

through the starting switch lever 442 to the nor-v mally closed switch 434 through the limit switch through the normally closed armature 42! of relay 4221?, thence through the holding coil 4!5 by means of the wire 4I1,-back to the power main 4812, thereby completing the circuit through the coil H5, which, upon being energized, attracts switch rod M6 to close the magnetic switch whereby to release the brakeMO and start the motor 52. The starting switch 442 may be instantly released because .a'holding circuit through the coil M5 has now been established. This circuit commences at lead 442 of ,the three phase source through the, holding coil M5,,closed armature 42! of relay 422 through closed limit switch 253, closed switch lever 434, through lead 436, and switch bar 438 which is now closed across terminals 43; and 439 and thence by lead 443 back to power lead 443. i

. The motor 32 continues to run until manual opening of switch lever 434 of the switch 430,, or

7 until opening of the limit switch 253 or until opening'of switch ii 6, which, as above described, is adjacent the joint of the toggle which is opened upon elevation of the measuring roll 5 (see Fig. *2). These three switches are all in series in the above described circuit and when any one of them is opened, it interrupts the circuit to the holding coil thereby permitting the bar M6 to move to the left, as indicated in the diagram, whereby to open the three phase switch.

The wiring circuit to my motor includes also ail-automatic stop mechanism which functions to stop the machine, in a manner now to bedescribed, upon the breaking of any of the yarns leading from the creel to the setting frame,

As indicated in Fig. 21, I may provide, adjacent the reed 4 andbetween it and the measuring rolls 5 and 6, a second reed 4G1 havinga rod 464 extending across the machine beneath the yarn and in proximity thereto. Tothis rod 464 is pivoted a large number of switch fingers 46!, and I preferably provide as many fingers I 46! as there are strands of yarn l entering from' the creel to the setting frame. The end 462 of each switch finger 46! extends between a pair of adjacent teeth on the reed 461 near the base of the teeth. The other end 453 of the switch finger, whichis the heavier end and which there-' by tends to rotate the finger in a clockwise direction about the pivot 46!], engages'a bar 464 made of electrically conductingmaterial. The bar 464 extends crosswise of the machine for the full length of the reed 461 and is insulated from the machineby. a suitable insulation mounting 465.

A wire 413 connects the bar 464 in a circuit hereinafter to be described.

The switch. fingers 46! are each made of elec-;

tricallyconducting material, as is the pivot rod 464 on which they are pivotally mounted and to which they are thereby electrically connected. The pivot rod 464 is carried by brackets 41! and is connected at terminal 412 to lead 415.

From the above description it is apparent that if leads 413 and 415 are connected in an electric circuit, this circuit will be open so long as all of the fingers 46! are maintained in their elevated positions shown in Fig. 21, out of contact with bar 454. The tension in the yarn; as it is fed through the reed 461 causes depression of the ends 462 of all the fingers 46!, thereby maintaining their ends 463 out of contact with the bar 454 and keeping the circuit open. However, if any one of the strands of the yarn! should break, during the winding, the tension on that strand will be released, as indicated in Fig. 22, permitting its correspondingswitch finger 46! to drop and close contact with the bar 464 thereby closing the circuit from lead 4'!!! to lead 415'. The lead 415 is connected to'the secondary 483 of a step-down transformer, which in turn is connected, by means ofthe wire 48!, with the solenoid 482 of a relay 433, the armature 484 of which is normally spring-pressed to open position away from the terminals485 and 486. The circuit through the. coil 482 is completed by means of the wire 414 which, as above noted, is electrically connected to the conductor bar 464.

The primary 490 of the transformer is connected by the lead49! to the .threephase power main 492 between the magnetic switch 430 and motor 52. The other terminal of theprimary is to the wire 49! which, as above noted, leads tov power main 402. The other terminal 485 of relay 483 is connected bythe wire 496 to the coil 491 of the aforesaid relay 422, the circuit through which is completed by means of the wire 498 which connects to the aforesaid wire 493.

The relays 483 and 422 are both time delayed relays and are each provided for this purp with a dashpot of well known construction. Be-

cause of dashpot 500, the relay 483, upon being.

energized, takes a period of two seconds before complete closing of the armature 484 across the terminals 485 and 485. The relay 422, on the contrary, is normally maintained in closed position and when it opens, through energizing of the coil 491, it opens instantly. It is provided, however, with a dashpot 50! whereby when coil 491 is again deenergized the movement of the armature 42! to closed position is delayed and takes a period of ten seconds until electrical contact is made.

With the device electrically connected as above described, when the magnetic switch 400 is closed by a'momentary closing of switch arm 442 of momentary contact switch 430 to start motor 52 as above described, the primary 490 of the transformer is energized by the flow of current through the leads 40f and 493. At the instant of starting of rotation of the winding rolls 20, 2'! and 22, the strands of yarn may be quite slack which might permit one or more of the fingers 45! to rest in electrical contact with the conductor bar 454 (Fig. 22). Such contact would complete a circuit through the leads 410 and 475 to the coil 482 of relay 483 toenergize the same and attract its armature 404. If the relay 483 were adapted to close instantly, the machine would again stop as a result of completion of the circuit through armature 484 of relay 483, from lead 49H through lead 496 tocoil 49"! of relay 422, thus attracting armature 42! to interrupt the circuit to holding coil 4! 5 of three phase switch 400. To prevent the machine thus stopping immediately as a result of slack in the yarn and to provide a brief time interval during which the yarn may assume its taut position, I provide dashpot 500 on relay 483 to eifect a two second delayin closing of armature 484. This interval .of two seconds is suificienli tol permit the yarn to become taut, thereby retracting the fingers 46! to their elevated positions ofFig. 21, out of contact with bar 464. This retraction of the switch fingers 46! again deenergizes the coilv 482 of relay 483 before its armature 484 has had time to complete the circuit, whereupon the armature returns to its fully open position of Fig. 21. The machine continues to run, if not stopped by one of the switches Elli, 253 or 434, until one of the strands of yarn breaks, which will again cause energizing of coil 482 of relay 483, and, after a two second interval during which the finger 46! will remain in its contactingposition'of Fig. 22, coil 491 of relay 422 will be energized, thereby opening switch 400 and stopping the motor.

The opening ofswitch 400 deenergizes the primary 490 of the transformer thereby instantly opening armature 484 of relay 483, and if the armature of relay 422 also immediately returned to its closed position, the operative could then start the machine without mending the bro-ken strand of yarn and the machine would run for two seconds before relay 484 wasagain opened. If the operative did not wish to take the pains to tie in the broken strand of yarn she could make the machine continue to run by manually holding up the switch finger 40! until the broken endis caught between the rolls and 6 when the tension of the yarn would hold the finger 46! in its elevated position and the machine would continue to run without the broken end having been tied in. To insure against such inefiicient operation and to induce her to tie the broken ends, I provide the dashpot 50! on the relay 422 to delay the closing of its armature 42! to starting position for a period of ten seconds. The operator can easily tie in the yarn within this inactive period and is thereby induced to do so.

While I have specified certain time intervals for the delayed actuation of the relays, obviously different time intervals can be employed if desired by adjustment of the dashpots inthe usual manners As stated above and as described in connection with diagrammatic Figures 5 and 6 of the drawings, in the preferred embodiment of my invention the initial winding roll with which the yarn comes in contact for either cverwinding or underwinding, is an idle roll, the next roll is driven at a predetermined rate of speed and the last roll is driven slightly more rapidly. For some purposes it may be desirable to make the initial roll, in either the overwinding or underwinding direction of rotation, a driven roll and I have provided a modification of my preferred embodiment in which the initial roll is a driven roll, the second roll is driven at a rate of speed slightly greater than that of the initial roll, and the third roll is driven at a rate of rotation slightly greater than that of the second roll in the series. As will appear from a detailed description of my modification, this relationship is preserved for either the overwinding or underwinding directions of rotation.

Fig. 23 of the drawings is a view illustrating such modification and corresponds to Fig. 9 of the drawings of the preferred embodiment of my invention. The pinion 10A corresponds to the pinion ":0 of Fig. 9 and is mounted on the drive shaft of a reversible electric motor connected in an electric circuit identical with that described in connection with Figs. 21 and 22. The pinion lllA'meshes with a large gear 530 which is fixed on-a shaft 53!. The shaft 53! carries splined to it the gears 502 and 503, which gears are cast on-the same hub, indicated at 504, which hub, with the gears 502 .and 503, may be slid longitudinally of the shaft 53! and for that purpose is grooved at 505 to receive trunnions 505 mounted on the ends of a bifurcated member 50'! on the end of arm 508 fixed on the end of shaft 509 which is suitably supported adjacent the frame of the machineand provided with a shifting hand lever 5|0 rigidly secured to the upper end of the rod 559 and adapted to rotate the same. By this mechanism it is apparent that shifting of the hand lever 5! 0 will shift gears 502 and 503 from their positions indicated in Fig. 24 in which the gear 503 is in mesh with a gear 5! and the gear 502 is not in mesh with any gear, to a position wherein the gear 503 is out of mesh and the gear 502 meshes with a gear 5|2.

The gears 5!! and 5!2 are secured to a shaft 5!3 to which is secured the roll 2!, which roll, as in my preferred embodiment, is mounted in fixed bearings (see Fig. 15).

The aforesaid shaft 53! which is rotated by the gear 530 fixed to it, like the shaft 59 (Fig. 9) of the preferred embodiment of my apparatus, carries fixed to it a gear 4IA, corresponding to gear 4! (Fig, 13) of the apparatus of my preferred embodiment, by means of which roll 20 is rotated. This roll, as in my preferred embodiment, is mounted in a movable bearing adapted, by pressure gears, to swing about the axis of th'eshaft 53L The gears 502 and 583 at times mesh respectively with idlers 526 and HI mounted onsuitable" stud shafts, which idlers in turn mesh respectively with gears 522 and523 which, as shown in Fig. 25, are secured to the shaft 524 rotatably mounted in the frame of the machine. The shaft 524 corresponds to the shaft IENB (Fig. 12) 'of my preferred embodiment andcarries the gear 228A,

by means of which the winding roll. 22 is driven, the said winding roll being mounted, as before, on a shaft which has a bearing adapted to swing about the axis of the shaft 524 toward and away from the spool during the winding operation.

The swinging of the rolls 2i and 22 toward and from the spool being wound, is eiiected in my modified embodiment in the samemanner as in ,tliepreferred embodiment, namely, by a set of a leading from a pressure gears '(not shown) pneumatic source of power. I With the modification constructed as above described, the motor is rotated to drive the pinion liiA in the desired direction, depending upon whether overwinding or underwinding is desired.

22 rotate at a certain predetermined rate of speed, the second roll 29 rotate at a speed slightly greaterthan that of the roll 22, and the roll 2| ,be driven at a speed slightly greater than that of the roll 26. For this purpose the gears 502 and W3 are disposed in the. position in which they are shown-in Fig. 24, by movement of the hand lever 5H3 if necessary, in which case the gear 563 meshes with the gear 5!! and also with idler 52! which,fin turn, drives gear 523which rotates the roll 22. Gear 523 has a greater number of teeth than gear 503, which latter gear in turn has a greater number of teeth thangear 51! which results in a moderate rotation. of roll 22, a slightly faster rotation of roll 28 and a still faster rotation of roll 2i, as is. desired for the overwinding or counter-clockwise direction ofrotation of the winding rolls. Y

In the underwinding direction of rotation the rolls 20, 2| and 22 each rotates clockwise by a reversal of direction of the motor which drives the pinion A, which is now also made to rotate clockwise.

rotates faster than the roll 20, the hand lever 510 is shifted until the gear 503 comes out of mesh with the gear 5 and idler 521, and the gear 592 meshes with the gear M2 and with idler 526. It will be noted that this shifting of the gears 502 and 563 on shaft 531 does not change thespe'ed of roll which rotates at the same speed both clockwise and counter-clockwise, determined partly by the ratio of pinion WA and gear m; The speed of rotation of roll 21 is, however, decreased relative to the speed of roll 20 and the speed of roll 22 increased relative to the speed of rotation of roll 25 by this shifting of the hand lever 5H3, because gear 5H2 has a greater number of teeth than gear 502 and the gear- W2 in turn has a greater number of teeth,

i is rotated through meshing of the gear 592 with I perform either or both of those functions.

In this direc- To produce the desired 'ratio of speeds, namely, that in which the roll 29 rotates faster than the roll'2l and the roll 22 in turn idler 520. r

In this manner all of the rolls are made powerdriven in both the overwinding and underwinding directions in my modified embodiment and the desired ratio of speeds to produce tensioning of the yarn. adjacent the spool is preserved regardless of direction of rotation. I

Qbviouslymypreferred embodiment is subject I Q to other modifications within the spirit of my invention which is to be limited only as indicated by the appended claims. Thus, although I have mined speeds for rotating the receiver and also I for swinging the rolls to apply'pressure to the receiver or spool being wound, Ido not wish to limit myself to, such mechanism but can obviously employ other mechanism, suchas belt drives to Nor is the predetermined speed at which each of the power-driven rolls is rotated necessarily a con- .stant speed but may be a variable predetermined speed effecting an increaseddiiferential of speed between the winding rolls as the spool fills whereby to increase the tension onthe yarn and thereby counteract the increased tendencytoward pufliness which may obtain after a considerable amount of yarn has been wound on the spool.

Obviously hydraulic, electrical or any means other than the pneumatically operated apparatus described maybe employed for, exerting the yielding pressure of the swinging winding rolls against the spool and for removing the top roll to replace the wound spool with an empty one,

provided the means chosen effects a yielding pressure which may be gradually applied and of any desired amount.

winding operation. For an effective winding operation it is not essential that the rolls assume this position at the very beginning of the winding operation because at that time the periphery of thespool with one or two layers of yarn is rela- ..tively small and proper tensioning of the yarn does not require equal spacing of the rolls throughout currently herewith, I may wish to direct the yarn in a straight line path from the guide roll l I, tangentially of the spool without being deflected by roll 2| during underwinding, or by roll 22 during .50 that small distance. vAs described in detail in my copending application Serial No. 45,839 filed conoverwindin which may be more conveniently accomplished by spacing the rolls .2! and 22 widely apart and' not equidistant relative to each other and to roll 20 during the initial winding rotation.
