SWANSON, OF CEANSTON, RHODE ISLAND, ASSIGNOB '10 UNIVERSAL WIND- ING COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS wmmne mom Y Application filed April 28,

This invention relates to improvements in winding machines for wmdmg cops, cones, coils, and other forms of packages from yarn,

thread and other strand materials.

In the following specification and claims the term package addition to controlling the winding operation, also regulates the point of delivery of v the yarn with respect to the package being wound.

. Another object of the invention is to provide means for directing the am from the bobbin or other source of supp y to the package being wound with its delivery point arranged to beshifted toward and away from the package in accordance with certain requirements.

Another object of the invention is to provide automatically-operated means for maintaining the delivery point of the yarn remote'from the package during the winding operation and for shifting it into adjacent relationship therewith when the op eration is arrested, whereby to render it more convenient to piece up the material or attach the end of the strand to the package.

Another object of the invention is to provide guiding-means across or over which the yarn from the supply leads with means operated automatically from the startingand stopping-mechanism of the machine to position the guiding-means adjacent the package being wound before the winding is started and to shift said guiding-means to a point remote from the package as the winding operation is commenced, thereafter returning it to first position when the winding operation isarrested.

Another object of the invention is to provide a winding machine wherein the supply 4 package, thetension-device and the. parts through or over. which the yarn feeds in delivering to the winding-mechanism may be is used in a general sense to indicate any form of product produced 1930: Serial in. 447,588.

located in close association with the package to facilitate threading the yarn therethrough, while at the same time maintaining the delivery point of the yarn from the supply in position remote from the package.

Another object of the invention is to provide means for shifting the delivery point of the yarn toward and away from the package which is operated automatically from a going element of the machine without attention on the part of the operator.

Another object of the invention is to provide an improved stopping-mechanism for arresting the operation of the-machine.

Further objects of the improvement are set forth in the followin specification which describes a preferred form of construction of ,the' invention, by way of example as illus-' trated in'the accompanying drawings. In the drawings:

' In practically all types of winding ma chines the supply for the yarn, whether a spool, bobbin, skein or other form offpacka'ge, must be located relatively remote rom the package being wound, and usually the supply is placed below the machine. It is of advantage, in fact quite necessary as will later appear, to have a considerable length of yarn between its point of delivery from the supply and the pomt where it is taken up by the winding, but where the supply bobbin is placed at some distance from the windingmechanism it is inconvenient of access to the operator and necessitates reaching or stooping to piece up the ends or to doff and replenish the supply. Even though the supply bobbin itself is placed nearthe package being wound the yarn must be carried to a point remote from the winding mechanism before it can be led to the package, and this also necessitates reaching or stoop'ing' on the part of the operator to place the yarn in or around the guiding-means from which it leads to the 7 package.

To overcome the inconvenience of locating the supply bobbin at a distance from the winding-mechanism the present invention contemplates a device whereby the supply may be located in close association with the winding-mechanism and theyarn carried over or through a guiding-means which maintains the delivery point at proper distance from the package being wound; the delivery point of the yarn being automatically controlled to shift it away from the winding-mechanismas the winding is started and to replace it n position adjacent the winding-mechanism when the operation of the machine is arrested so as to facilitate the piecing up of broken ends and the attaching of the yarn to the package being wound. The accompanying drawingsillustrate a winding machine of the.

Reece, dated March 4, 1930; but it is'to be rom the bed or table 2 are brackets or framemembers 4 which carry bearings. for the rotat-' ing drive-shaft. 5 and other parts of the winding-mechanism. As herein shown the driveshaft 5 is journaled in ballbearings 6 carried on the brackets 4 and extends horizontally throughout the. length of. the gang machine.

- to serve as a drive for all of the units thereof.

The shaft 5 carries a series of drums or driverolls 7, only one of which isshown in the present drawings, it being understood that a separate rollis unit.

The drive-roll 7 serves as the means for rotating the package by contact with its surface and, in accordance with the invention of the patent hereinabove referred to, the roll provided "for each winding 7 is also constituted as a means for traversing the yarn longitudinally of the package to deposit it in helical coils forming the layers which build u the yarn mass. For this purpose the roll g, which may be termed a traverse-roll, is provided on its peripheral surface with a yarn receiving and guiding groove .in which it is traveling to prevent it i from being diverted into the opposite helix of the groove, all as fully set forth and illustrated in the patent hereinabove referred to.

As before indicated, the product of the machine may be a package of any preferred form, the usual shape being cylindrical or I conical. The yarn is wound on a suitable receiver ,or core such as a aper tube or a wooden or fiber mandrel. is illustrated in the present drawings the machine is adapted for winding conical packages and for this purpose a cone-tube or receiver 0 is rotatably mounted on a dead-spindle 10. To provide that the axis of the package may recede from the dri'veor traverse-roll 7 during the growth in the windin the winding-spindle 10 is carried at the en of a swingin arm 11 pivoted on a horizontal stud 12 whic is supportedin 'a hub at the upper end of an upright 14 formed as a part of the frame-memher, or bracket 4. The arm 11 is constructed in two parts, with an outer extension 15 arranged to swivel in a hearing at the end of the main arm to adapt the winding-spindle 10 to assume an inclined osition with respect to the surface of the roll The wooden tube or yarn-receiver C is held on the winding-spindle 10 by means of a latch 16 i at its outer end.

In'machines of the present type the driveor traverse-roll 7 is. rotated continuously and to arrest the winding operation the pack age is removed from contact with the roll through the operation of stopping-mechanism arranged as next described. Means are usually provided for actuatin the stoppingmechanlsm automatically w en the yarn breaks or its supply is exhausted, and. also a when the package reaches a predetermined diameter. The arm 11 carrglmg the windingspindle 10 has a downwar' yextending leg 18, to the end of which is pivotally connected a bar or slide 20.v The rearward end of the bar 20 is formed with a slot 21 engaged by a pin 22 fast in the end of the leg 18, and aspring 23 held in a bore in the end of the bar acts on a plunger 24 hearing against the pin 22. Through this arrangement the connection between the bar 20 and the arm 11 is cushioned to allow a slight play between the parts. The bar 20 extends forwardly and downwardly and at its free end has a series 1 pawl 26, whereby the ratchetteeth 25 on the at are successively engaged thereby. To arrest the winding 0 eration the bar 20 is drawn forward by roc ing the pawl 26 under the swinging action of the lever 27.

Referring particularly to Fig. 4 of the drawings, the lever 27 is pivoted on studs 30 carried in hubs or bearings 31 formed on the frame-members 4. Pivoted to the free end of the lever 27 at 32 is a yoke-shaped dog 33, the lower-end of which is adapted to make contact with a cam-shaped hunter 35 held fast on a shaft 36 and continuously rotated in the direction indicatedby the arrow. The shaft 36 is journaled in bearings 37 in the frame-members 4 and may be connected by gearing or otherwise to be driven with or from the traverse-roll shaft 5 at a much slower rate of speed.

The lever 27 is substantially U-shaped,

v having op osite forwardly-extendin arms 29 I connected y a late 38 which norma y stands in substantia y vertical position, as illus- 35 trated in Fig. 2, and serves as a thread-guard with its upper end in front of the traverseroll 7. Referring to Fig. 1 of the drawings, ears 39 project forwardly from the plate 38 to provide bearings for a wire thread-bail 40 of inverted U-shape. The ends of the legs of the wire bail 40 are bent around at 41 to form bearings encircling pins 42 driven through the sides of the lugs 39. Extending from one of the legs of'the bail is a tail-piece 43 which is adapted to strike against a shoulder 44, see Fig. 4, between the lugs to act as a stop to limit the forward tilting action of the bail. The thread-bail. 40 has a cross-bar 45 over which the yarn 3 leads to the grooves 8 in the traverse-roll 7 as illustrated in Fig. 2, and when the strand breaks or its supply is exhausted the bar tilts forward under the action of a lever 48.

The lever 48 is pivoted on the pin 42 ad by a box-like casing-49 projecting from the front of the plate or threadard 38. The right-hand leg of the thread-bail 40 has an it to strike against the rearward edge of t e lever 48, whereby when the lower end of the lever is swun to the right, as viewed in Fig. 2, it will roc the.upper end of the threadbail outwardly, this motion being ermitted when the upper cross-bar 45 of the ail is released by the breakage or running out of the yarn y. The lower end of the lever 48 carries a pin 51, to which is connected a spring having its opposite end anchored-to the dog 33 at 56. The spring 55 is normally without tension, formin a link or connection between the lever 48 and the dog 33 whereby to maintain the latter normally lifted away from contact with the hunter-cam 35. When,

however, the thread-bail 40 is released from .the tension of the yarn y it allows the lever acts on the dog 33 'to rock the lever 27 and its pawl 26 whereby to slide the bar 20 to raise the package off from the drive-roll 7 extension 50 bent around in an elbow to ada t to arrest the winding operation; As the forward end of the lever 27 is rocked downwardl the lower end of the lever 48 isv broug t against an inclined abutment '57 on the side of the bracket 4. This latter engagement swings the lever 48 to stretch the spring 55 whereby the tension of the latter will cause the do' .33 to be swung forwardly as soon as it is re eased from the banter-cam :A flat leaf-spring 60, fastened to the end I lifting action of the dog 33 on its rearward end, see Fig. 4, it islocked in this position by means of a latching engagement with a starting-lever 65. The starting-lever 65 is Socured fastto a rod or rock-shaft 66 by means of a set-screw 67. The shaft 66 is rockable in bearing-hubs 68 on the opposite framemembers 4. The starting-lever 65 reaches forwardly at the left-hand side of the winding-mechanism "with its bottom edge riding across a recessed edge 69 on the plate or thread-guard 38, see Fig. 1. The forward end of the starting-lever 65 is formed with a handle projecting outwardly beyond the thread-guard 38, and inwardly therefrom is a notched detent-shoulder 71 adapted to lock against the edge 69 of the plate 38 in the 'manner shown in Fig. 4 of the drawings.

he longer, downwardly-extending arm 79 of the lever is formed with a lug or from the side of the weight 82 is a abutment '80 adapted to strike against the edge of a ivoted weight 82, one of the ele ments of t e sizing-stop of the machine, to return this part to first position in the manner as later explained.

The sizing-stop, that is the means for arresting the winding operation when the package reaches the desired size, is constructed as next described. The sector-shaped weight 82 is rockable on the in 32 at the end of the lever 27, see 5, eing disposedat one side of the yoke o the dog 33. Projectilg normall bearing against the side of t e dog 33 toa apt it to rock the latter *down into position to be engaged by the bunter-cam 3 5 when the weight drops. The weight 82 s normally maintained suspended in the position illustrated in Fig. 4 through the means of a laterally movable latch 85. which extends rearwardly from its pivot. Referrm particularly to Fig. 5, the latch 85 is forme with ears 86 which straddle a lug 87 projecting from the hub of the weight 82 with a pin 88 inserted therethrough to Not the latch to the weight. A plunger 89 el'd in a lateral bore in the side of the weight 82 is I through a slot 98 in the arm. By loosening" ur d outwardly; by a spring 90 to bear ag i nst the rear end or tail iece ofthe latch 85 whereb weight. finger 91 is bent over from the side of the latch 85 to bear against the lug 87 to limit the swinging movement-0f the latch under the action of the spring-plunger 89. The opposite free end of the latch 85 is bent at right angles to form a detent-catch 92 or latch proper which is normally engaged beneath the underside of a ledge 94 projecting from the side of, an arm 95 fastened to the rack-bai'20. The upper part of the arm 95 fits against the side ofthe bar 20 and is provided with a lip 96 overhanging the topof the bar. The arm 95 is secured to the bar20' by means of a bolt 97 passing the bolt 97 the arm 95 may be slid along the bar 20 to adjust its ledge 94 with ct to the detent 92 on the latch 85 so as to ti e v I r I I the package into contact with the drive-roll 7.

to hold it in almement with the a bracket 100.

the sizing-stop to arrest the winding opera-- tion when the package reaches any desired diameter. It will be understood that as the' bar 20 slides outwardly across the dog 86 70 with the rising of'the arm 11,-as cause the growth in the winding, the led e 94 on the arm 95 will eventually ride off rom the end of the latch 85. This action releases the weight '82 to allow it to drop whereb its pin 83 acts against the dog- 33 to swing the latter into position to be engaged by the huntercam 35. It is to be particularl noted that the or packages fromwhich the yarn is delivered to the winding is mounted oh ,a vertical frame or bracket 100 which also 5 pports the tension-device and the movab e yarn-guidin means for shifting the pointof delivery 0 the strand with respect to the packa e bein wound. A bracket 100 is ot eacfi rovided of the winding units an as a convenient means of support therefor a horizontal rod 101 is mounted in arms 102 clamped to the legs 3 of the gang machine. The bracket 100 comprises a member 103 having a hubheld fast on the rod 101 by set-screws 104; or other suitable means and. provided with arms 105 bolted to a flange 106 projecting from the side of the vertical sion of the flange-106is formed with a slot 107 which serves as a mounting for the supply-holder. The su ply-holder may be of any suitable type an as herein shown consists of a bracket 110 fastened to the an e 106 by means of bolts lll'passing through e slot 107. Throu h this arrangement the bracket 110 may ad'usted vertically to locate the bobbin or 0th carried'thereon in proper relation to the'tension-device, indicated generall at 120, whichv upper end 0 the frame or is carried at the The supply-holder bracket 110 has a de-' pending arm 112 terminatin in ahub 113, on which is rotatably moun a spoked member 114'.

of the yarn therefrom, so that the operator ,is not required to stretch or stoop in tending the machine. o

Any suitable type of tension-device may be employed on the winding machine and the present drawings illustrate a disk-tension of Fastened to a lateral ear or flange 121 on the side of the frame 100 is a bracket 122 provided with bearings 123 for a horizontal in or spindle 124, on which are mounted a pair of tensiondisks 125. The tension-disks 125 are of the usual concave-convex form arranged with their abutting faces in line with the axis of the bobbin B to adapt the yarn y to draw therebetween. One 'ofthe disks 125 is held from lateral displacement and the other is acted upon by a helical spring 126 on the spindle 124 topress it toward the relatively fixed disk. Suitable weights 127, carried on a lever 128 which is pivotedto the tension bracket at 129, act to slide the spindle 124 to hold the spring against the side of the tension-disk to maintain the disks in yielding contact with the yarn drawing through the device.

' The tension-bracket 122 is formed with circular flanges130, see Fig. 2, projecting outwardly in curved ears 131 which form a guideway for directing the yarn into position between the tension-disks; -Mounted on the tension-bracket 122 below the tension-device is a slub-catcher 132 for cleaning the yarn, and below this is a guide 133 through which the yarn draws to maintain it in line with the opening in the slub-catcher. A wire guide 134 beneath the guide 133 is provided to facilitate the operation of threading the yarn into the guide 133 and through the slubcatcher 132. Extending between the flanges 130 of the tension-bracket 122 is a stud or pin 135 on which is mounted a roller 136, pref:

erably of porcelain or other wear-resisting material. The yarn y draws through the tension-device and around the porcelain roller anism when the winding operation is arrested and remote from the package during the winding. For this purpose the yarn-gulding means or pin 140 is mounted on a weight or slide 141 adapted to be raised and lowered on the frame 100. The slide 141 consists of a plate or block having a hole in its upper end in which the pin 140 is secured by means of a set-screw 142. Projecting rearwardly from the slide 141 are studs 143 fitted to slide in a vertical slot 144 which extends from top to bottom of the frame 100 The studs 143 have Washers 146 overlapping the sides of the slot 144 on the rearward side of the frame 100, with cotter-pins 145 for holding the slide against the'front face of the frame. Throu h this arrangement the frame 100 forms a trac way with the slide 141 arranged to be moved 'up and down thereon. The downward movement of the slide 141 is limited by contact of its lower edge with a washer 147 held in place by a bolt 148 extending through the slot 144, the stop for the slide may be adpasses through the upper stud 143 and leads around a sheave or pulley 152 pivoted on a pin 153 at the top of the frame 100. The cord 15 0 passes down around a similar sheave 154 journaled on a pin 156 and thence draws to the drum 155 with its end passed through a hole in the flange thereof and knotted to secure itthereto, see Fig. 6. The wind-up drum 155 is operated automaticallv from the starting and stopping-mechanism of the machine to lower the slide. 141 when the windingmechanism starts to operate, and to return the slide to its upper position when the winding operation is arrested. The automatic means for controlling theoperation of the wind-up drum 155 is organized as next described.

Referring particularly to Fig. 6 of the drawings, the drum 155 is normally free rotatively with respect to the continuously a against the side of the bunter-cam35 which is held fast on the shaft 36, and its opposite end has an overhanging rim 157 provided on its side with ratchet teeth 158. The ratchet teeth 158 are adapted to engage similar teeth 159 on .a ratchet-disk 160 which is freely rotatable on a sleeve 161 secured fast to the shaft 36 by means of a set-screw 162. The

sleeve 161 carries a hub or collar 163 held means of a cord 150 which iswound upon a drum 155 carried on the shaft 36. The cord 150 is attached to the cotter-pin 145 whichfast therewith by means of the set-screw 162 which passes through both elements. In the hub 163 .--are ockets 164 holding helical springs 165 w ich bear against a disk or washer-166 rotatable on the sleeve 161. Between the washer 166 and the ratchet-disk 160 is a friction disk or washer 167, preferably constructed of fiber, leather or some similar material. Thesprings 165 act to urge the washer 166 toward the disk 160 to provide frictional contact of the friction' sleeve 161 is a helical spring 170 coiled around the shaft 36 with its opposite end bearing against the hub of the drum 155. Normally, the spring 17 0 maintains the drum 155 slid to the right as viewed in Fi 6, with its hub bearing against the hub o the hunter-cam '35. The drum 155 is slid to the left against the tension of the spring 170, to engage its ratchet teeth 158 with the teeth 159 on the disk 160 and through this connection the drum may be frictionally driven from the hub 163.

The shifting of the drum 155 to clutch it with the friction drive is effected bymeans of a clutch-lever 172 o erated from the stopping-mechanism of t e machine. Referring to Fig; 4, the clutch-lever 172 is of elbowshape, having a flanged end 173 secured to the back of the plate or thread-guard 38 by means of screws 174. The free end of the clutch-lever 172 has an offset toe 175 which is beveled on its edge to adapt it to ride against a radial shoulder 176 on theflange 157 of the drum 155 whereby to shift the drum to engage its teeth 158 with the teeth 159 on the ratchet-disk 160. This engagement is effected when the lever 27 is rocked into the osition illustrated in Fig. 4 to arrest the win ing operation, the drum 155 being thereby clutched to the disk 160 which is frictionally driven from the hub 163 to turn the drum to wind up the cord 150. As the cord 150 is wound onto the drum 155 the slide 141 is raised to the top of the frame or trackway 100 where its movement is arrested as the stud 143 comes against the end of the slot 144. At this juncture the ratchet on the drum 155 will still remain engaged with the ratchet-disk 160, but the friction clutch between the disk and the hub 163 will allow slippage so that the drum will come tion, Figs. 7 and 8 of the drawings illustrate a slide 177 having the tension device mounted thereon to adapt it to be shifted from-an elevated position to a point therebelow in delivering the yarn to the windingthe stud 178 between the plates 17 9 and 180' and are pressed together by means of a helical spring 184 held by a nut 185 screwed onto the end of the stud.

A- bracket 186 near the top of the frame 100 carries the ,slub-catcher 132, guides 133 and 134 of the same arrangement as previously described. A pair of spaced hornshaped threading-guides 188 are also mounted on the bracket 186 for directing the yarn across a pin or roller 189, whence it leads over a roller 190 and down through the shiftable tension-device.

The method of operation of themachlne embodying the present invention is as next explained. Referring to Figs. and 2 of the drawings, to prepare the machlne for winding, a supply bobbin B is placed on one of the spindles 115 of the supply-holder and turned up into vertical position. The yarn y is drawn .ofl from the bobbin, led through the thread- guides 134 and 133, thence passed through the slub-catcher 132 and drawn be-' tween the guards or ears 131 which direct it between the tension-disks 125.

When the winding operation is arrested the slide 141 is suspended at the upper end of the guideway or frame 100 as illustrated in 3, and in threading up the machine the yarn y is drawn rearwardly from the tensiondevice under the guiding-pin or stud 140 to attach its end to the yarn-receiver or conetube 0 which has previously beenmounted on the spindle 10 and secured in place by turning up the latch 16, see Fig. 1.

To start the winding operation the handle 70 is lifted to cause the upper arm 77 of the bell-crank lever 7 5 to be .raised to raise the rack-bar 20 to free its teeth 25 from the dog or pawl 26. As the rack-bar 20 is released arm 11 and its associated parts will rock the spindle 10 downwardl to place the surface of the yarn-receiver (d in contact with the continuously rotating driveor traverse-roll 7. As this; contact is accomplished the roll 7 starts rotation of the yarn-receiver C whereby to wind the yarn thereon. As the yarn commences to wind onto the receiver 0 it is from this latter engagement the weight of the picked up by the groove 8 in the roll 7 and thereby caused to be traversed back and forth longitudinally of the receiver to .deposit it in helical coils thereon as indicated at y in Fig. 1.

Prior to the starting of the machine the dog 33 has been carried out of range of the bunter-cam 35 under the action of the spring 55 in the manner as hereinafter explained. Upon the lifting of the starting-lever 65its detent-shoulder 71 is released from the edge of the plate 38, see Fig. 4, so that the lever 27 is allowed to return into horizontal position as shown in Fig. 2 under the action of the leaf-spring 60. As the lever 27 returns to first position the pawl 26 will engage the appropriate tooth 25 on the rack-bar 20 whereby to set the stopping-mechanism for operation in the manner as later explained. Meanwhile; the return motion of the lever. 27 swings the clutch-lever 172 away from the flange 176 on the wind-up drum 155 whereby the spring 170 acts to slide the latter to disengage its teeth 158 from the teeth 159'on the ratchetdisk or clutch-member 160.

This release of the drum 155 takes place immediately the starting-lever 65 is lifted-to start the winding operation and allows the drum'155 to pay out the cord 150 to lower the slide 141 on its trackway on the frame or bracket 100. It has been stated that the yarn y is carried to the yarn-receiver C, or to the package being wound, beneath the guide-pin 140 when the winding machine is of the operator. With the parts of themathreaded up and, consequently, as the slide 141 descends on its trackway it will form a loop in the yarn as indicated in Fig. 2, the

strand passing from 'the tension-device 120 over the porcelain roll 136 and down under the pin 140, whence it draws upwardly across the bar 45 of the thread-bail 40. From the.

chine in the position as illustrated in Fig. 2 the yarn feeds through the tension-device 120 and thence is drawn downwardly around the guiding-pin 140 to stretch it out in a loop which provides a considerable length of yarn between this last delivery point and the package being wound.

When the yarn breaks or its supply is ex hausted the winding operation is arrested automatically through the operation of the stopping-mechanism as next explained.

The breakage of the strand or the running out of the yarn releases the thread-bail 40 to allow the lever 48 to swing to the right as viewed in Fig. 2. The release of the lever 48 permits the dog 33, connected thereto by the spring 55, to drop down into vertical position whereby its end will be engaged with the eccentric periphery of the banter-cam 35 j as the latter rotates with the shaft 36. The effect of this engagement is to cause the dog 33 to be forced upwardly in the manner as indicated in Fig. 3 to tilt the rearward end of the lever 27 upwardly and rock its forward end downwardly. This rocking action ofthe lever 27 causes the pawl 26 carried thereby to draw the rack-bar 20 forwardly whereby to swing the arm 11 upwardly to raise the package off from the drive-roll 7 as shown in Fig. 3. As the forward end of the lever 27 is rocked downwardly the lower end of the lever 48 rides against the inclined face 57, which, as previously described, is formed as a part of the fixed frame-member 4, and thereby the lever 48 is swung outwardly to stretch the spring 55 connected to the dog 33. As the spring 55 is placed under tension it acts to draw the dog 33 to the right, as viewed in Fig. 4, immediately the lower end of the latter is released from the'bunter-ca m 35 so as to prevent further movement of the dog from the cam. Previous to the release of the dog 33 the starting-lever 65, which rides across the edge 69 of the plate 38, drops un der the action of gravity to engage its detentshoulder 71 with the plate in the manner as illustrated in Fig. 4 to hold the lever 27 from I returning to first position. The parts of the stopping-mechanism are thus locked to retain the rack-bar 20 in forward position to maintain the package lifted off from the drive-roll 7 until it is desired to again start the winding operation.

As the lever 27 is rocked into the position illustrated in Figs. 3 and 4 to effect the stopping of the machine the clutch-lever17 2 carried thereby is moved to shift'the wind-up drum 155 to engage its clutch to cause it to be rotated from the shaft 36. Referring to Fig.

6, the beveled toe 175 of the clutch-lever 172 is carried against the flange ,176 to slide the drum 155 to the left against the tension of the spring 170. Through this action the teeth 158 onthe drum are brought into engagement with the teeth 159 on the ratchet-disk 160. It has been explained that the ratchetor clutch-disk 160 is driven frictionally through the medium of the washers 166 and 167 connecting it with the continuously rotating hub 163 carried by the sleeve 161. Consequently,

as the drum 155 is connected to the clutchdisk 160 it will be rotated therefrom in the direction indicated by the arrow in Fig. 6

whereby to Wind the cord 150 on its barrel.

against the end of the slot 144 to act as a stop. As the slide 141 is raised on the frame package being wound. For t is reason the operator is not required to stoop or reach downwardly in threading up the machine.

As the slide 141 comes to a stop at the top of the frame or bracket 100 the rotation of the drum 155 is arrested as provided for by theslippage between the friction washer 167 v and the parts of the clutch engaging therewith. Very little power is required to raise the slide 141 on its trackwayand hence the slipping of the clutch as the rotation of the drum 155 is arrested will not cause material wear on parts.

The arrestment of the, winding operation when the package reaches the desired size is effected by the actuation of the stoppingmechanism from the sizin -stop previous y described. Referring to ig. 4, the arm 95 is adjusted along the rack-bar so that the ledge 94; on its lower end will ride off from the detent '92 of the latch ,85 when the package reaches the predetermined size. As the latch 85 is released-from the ledge 94 it allows the weight 82 to drop, whereby its pin 83' swings the dog 33 down into positlon to be engaged and acted upon by the banter-cam 35. The engagement of the dog 33 with the bunter-cam 35 then effects the stopping of the machine in precisely the same manner as above described as the various instrumentalities perform their several functions; the drum- 155 being clutched to the shaft 36 to cause it to wind up the cord 150 to raise the slide 141 to the top of the frame 100.

In returning the parts of the sizing-stop to first position after the action of the stopping-mechanism the lifting of the starting leverrocks the bell-crank lever to cause the lug on its arm 79 to swing the weight 82 upwardly to again engage the latch 85 with the ledge 94 .on the arm 95 in the manner as previously explained.

In the modified form of the invention as illustrated in Figs. 7 and 8 the operation of the parts issubstantially the same as above described. That is to say, under the action of the stopping-mechanism the drum 155 is clutched to the shaft 36 to cause it to wind up the cord 150 to raise the slide 177 to the top of the frame 100. On the other hand, upon starting the machine the, clutch is released to free the drum 155 to cause it to pay out the cord 150 to lower the slide 177 to the position illustrated in Figs. 7 and 8. The raising of the slide shifts the tension-device 180 upwardly into accessible location when the winding 0 ration is arrested, whereby to facilitate th threading of the yarn into place therein; and the lowering of the tensiondevice carries the delivery point of the yarn a'wa from the package being wound as the win in operation is started.

It wi be observed from the foregoing that the present invention provides an improved construction of stopping-mechanism for winding machines having means associated therewith and operated automatically therefrom to adjust the oint of delivery of the am with respect to t e package being wound. hrough this arrangement the supply bobbin from which the yarn delivers and the slabcatcher, tension-device and other placed within convenient reach to relieve the operator from the necessity for stooping and reaching in tending the machine. For this reason the machine can be tended with less 1 efiort and fatigue on the part of the operatorv and with a saving of time which results in ing, one advantage being that when a break occurs, near the supply, as is usually the case, the broken end will not run into the winding before the rotation of the package is arrested. For this reason the broken end may be more readily recovered. As another advantage the provision of a relatively long length of free yarn between the delivery arts through which the yarn must be threade are point and the traverse-mechanism tends to revent the strand from jumpin out or be- 7 mg dislodged from the groove 8 111 the travarse-r0117. The extended length of yarn also provides for easier action duringthe traverse of the yarn, since it is not required to make,.'

an abrupt bend in the strand at the delivery point when the direction of its traverse is reversed. v
