Application led June 1,

To all whom t may concern:

Be it known that IJCUTLER D. Known TON, a citizen of the United States, and residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Winding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to winding machines, and more particularly to machines for reeling silk, linen, and other character of filaments into skeins.

Heretofore it has been the. practice to form skeins of filaments by Winding thefilament upon a reel, and tying the. filaments together when the predetermined' number tobe contained in the skein has been wound. vIn machines of this general class, it has been. the

common practice to wind the filament upon the reel by rotating the reel and drawing the filament from a source of supply. This manner of forming the skein has been satisfactory so far as the skein formation is concerned, but it required that the reel be stopped Whenever the skein was to be tied, and consequently, the output ofthe machine was restricted and loss occurred incident to the repeated stopping of the machine or the winding operation.

An im'portant feature of the present invention consists of winding the filament upon a reel and tying each skein as it is formed or completed, without stopping the lwinding operation. The effect is that the output of the machine is greatly increased, and economy of product results.

In carrying this feature of the invention into practical effect, it has been found expedient to rotate a flyer about a stationary or fixed reel, so that the knotting or tying mechanism which is utilized to tie each completed skein, may be properly related to the reel and skein at all times, and ready to perform the tying operation.

Heretofore it has been the practice totie the skein, yor bind it upin the position in WINDING k.lIACIilIINE- 1920. serial No. 385,606.

which the skein was wound upon the reel, and after thereel had been brought-to rest. In the present invention, however, where eac-h succeeding skein is being wound during the vtying of a previously-wound skein, the skein to be tiedis moved from the position in which it was Wound to a second or tying position; and an important feature of the present invention, therefore, consists in winding the skein in one position and transferring it to another position for the tying operation. In carrying this feature of the invention into effect, it has been found expedient to move the skein from the Winding to the tying position just prior to laying the final coil of the skein in position, and to utilize the movement of the Hier at such times to place the final run of the rskein under control of the knot-tying mechanism. An important feature ofthe invention in this respect, therefore, consists of means for placing 'the filament in control of the knotter ortying mechanism while the winding operation continues.

The knetter or tying mechanism acts upon both ends of the skein to vpass these ends about the skein after having been crossed, and forming the knot. Where the flyer is utilized to lay the filament upon the reel, either by rotating movement of the reel or rotating movement of the flier1 the tension of the filament as it is drawn. from the source of supply keeps it taut.; and to provide sufficient slack for the tying operation, another feature of the invention consists of means for producing sufficient slack in the filament during the skein-Winding operation, to tie the knot.

During the operation of the machine of t-he present invention, one skein after another is formed upon the reel and tied without interrupting the winding operation, and it becomes necessary from time to time to remove the skeins from the reel. while theA machine still continues to operate. An important feature of the invention in this respect consists in a reel support which may be moved to and from supporting position at will, to permit the tied skeins to be re moved from the end of the reel. Where the reel is mounted with its axis in a vertical position, as in the present foi-in of the 1nvention, the reinoi-able reel-supporting means may be conveniently associated with the lower end of the reel and formed of two or more reel-supporting elements which may be alternately moved into and out of reelsupporting position.

In the present. invention, the knotter is normally at rest and when a knot is to be' tied, it is brought into active operation. Inasinuch as some kind of filaments may be unduly strained or even ruptured .by a sudden jerk or pull theieon, the present invention provides means for obviating this defect-ive operation. An important feature of thel present invention in this respect consists. of means for starting the knotter or tying mechanism with a rela-tively slow movement, rogressively increasing the speed of the iinotter to a maximum, and then gradually bringingit to rest.

Heretofore, it has been the usual practice to stop the Awinding operation of a skein winding machine upon the completion of each skein. This has been rendered .necessary on account of the relation of the reel and knotter or tying mechanism. In the present invention, however, the winding operation continues until a predetermined number of skeins have been wound, and then the machine is automatic-ally stopped. A further important feature of the pi'esent invention, therefore, consists of means for stopping the machine when a predetermined number of completed skeins have been wound and tied.

The above features of the invention and other novel elements and combinations of parts will be hereinafter describedin connection with the accompanying drawings which form one good, practical form of the invention.

The machine frame may be of suitable form and character for supporting the operating parts, and in the present instance, comprises a lower frame or table 1 having an upper frame or head 2 supported in spaced relation thereto by posts 3. The table 1 may be supported by spaced brackets 4 having a bridge member 5 and connecting rods 6 extending between them.

Above the table 1 is supported a drum .7 preferably in the form of a hollow cylinder, as clearly shown in Fig. 6. The drinn 7 is provided with an upper and lower row of lugs 8 positioned in vertical alignment, and arranged in pairs, which serve to adjustably support the vertical rails 9 which constitute what will hereinafter be termedthe reel.

adjustably secured to the lugs, for a purpose to be described.

Mounted in suitable bearings on the upper frame or head 2 is a driving shaft 11 provided with a pulley1 adapted to be driven by a belt from a suitable source of power.

This pulley is mounted loosely on the shaft 11, and is operatively connected thereto at times by clutch mechanism of any suitable construction. The clutch member 13 is splined on the shaft and is moved into and out of gripping engagement with the companion clutch member or pulley 12 by the lever 14 pivotally mounted on the arm 15 at 16. The lever is operatively connected to the clutch member 13 by pins extending into the annula-r groove formedhin the collar 17 of the clutch member 13. A lever 18 is pivotally connected to the bracket l at 19 and has a handle 20. The lever 14 is yieldingly connected to the lever 18 by a pin 21 secured tothe lever 14 and having a spring 22 confined between the head of this pin and a face of the lever 18. The lever 18 may be actuated to engage the clutch members and may be held in this position by a rod 21a pivotally connected to the lever 18 and having a notch 22 engageable over a fixed pin 23. A spring 24 is provided to hold the rod 21 in engagement with the pin.

It is desirable to bring the machine to rest promptly when the clutch members are disengaged, and to this end the clutch member 13 has a flange 28 which is forced into engagement with a. brake shoe 29 under the impulse of a spring 26 which acts upon the extension of the lever 14.

Secured on the shaft 11, Fig. 3, is a spiral gear 30 which meshes. with a similar gear 31 secured upon a second shaft 32. The inner end of the shaft 11 has a bevel gear 33, Figs. 2 and 3, secured thereto, and meshing with a bevel gear 34 mounted on the hollow vertical shaft 35, Figs. 1 and 3, which extends below the lower face of the head 2. The flyerA 36 is secured to and rotated by the shaft 35. and has 'a downwardly-projecting portion 37 for laying the filament upon the reel, as will more fully appear. The filament to be formed into skeins may be led from any suitable source, such as a spool or cheese 39 upon the stand 40, to a bracket 41 supported above the shaft 35, and down through the hollow shaft to the flyer, as shown in Figs. 1, 2 and 12.

A disc or bracket 42 is secured to the upper portion of the shaft 35, Figs. 1 and 4,

and has pivotally secured thereto a pair of centrifugally operated arms 43 upon the upper ends of which are hooks 44, and upon the lower ends are the lateral extensions 45.4 As long as the filament is supplied to the iiyer under the desired tension, thehooks 44 will hold the arms 43 from swinging outwardl by centrifugal force, but if the filament reaks or becomes too slack, the arms will fly outwardly sufficient to bring the extensions 45 into position to engage the finger 46 secured to the vertical rod 47 and rock the rod, Fig. 4. Projecting from the rod 47 is the finger 48 bearing against a. shoulder .50 upon the rod 49 which is normally held in its retracted position by a spring 51 po.-

sitionedibetween a shoulder 52 upon the rod and a fixed bracket 53, the construction being such that longitudinal movement ofthe rod 49 will disengage the rod 21a'from the lu 23 and stop the machine.

ien the flyer 36 has, laid or' wound upon the reel the desired number of coils to constitute a skein, theI resent invention contemplates that the co1ls or windings be tied or bound together without the necessity of stopping the winding of successive coils or skeins, and a good form of means to this end will now be explained.

The shaft 32, which is driven from the main shaft 11 in the manner above described,

operates a train of mechanism so that when a predetermined number of coils have been placed upon the reel, the shaft 54 (Figs. 1 and 3) will be actuated to tie or bind the coils together as a skein. The shaft 54 extends past the vertical shaft 35, and is provlded with al skew bevel gear 55 which meshes with a similar gear 56 secured to a sleeve 57 rotatably mounted about the shaft 35. The lower end of the sleeve v57 has a gear 58 secured thereto and this gear meshes with an elongated pinion 59 mounted on a shaft 60, to the lower end of which .is secured a pinion 61. The shaft 60 is rotatably mounted in a frame 62 rigidly secured to the flyer arm 36 so that the shaft 60 swings about the gear 58 when the flyer is rotated and the elongated pinion 59 rolls about the gear 58 Without rotating the latter. A gear 63 of the same size as the gear 58 is mounted to mesh with the pinion 61 and these two gears are preferably enclosed in a casing as shown best in Fig. 12. The gear 63is secured to a stub shaft 64 which is connected to rotate with the shaft 65 in alignment therewith. In the present instance, the connection consists of a coupling such as 66, the construction being such that one shaft is permitted to move laterally slightly relative to the other shaft. The shaft 65 extends into the drum 7, Fig. 6, to operate the tying mechanism, and the lower end of the shaft 65 preferably rotates in the bearing 67 formed in the crossbrace 68, Fig. 8.

gitudinal movement while the gear 74 is held against such movement and in opera-' tive connection with the gea-r 73. The gear 74 is driven by the shaft 65 by means of a head 75 secured to the shaft, and a similar in the rails 9, differ from the ends mounted in the rails 9 in that the former have pusher members 86 pivotally secured thereto by a and connected parts, but this is desirable since in moving the spider and flyer u and down s1mu1taneously, the coils are a ways head 76 secured to the gear 74, and the twaid lust below the SlllfilCe 84: 0f the Spider heads are connected by the pins 77.

The construction of the mechanism for operating the shaft 65 is such that the shaft 65 will be rotated when the shaft 54 is rotated, but will not be rotated by the rotation of the -flyer. This is due to the fact that since the l gears 58 and 63 are of the same size, the

pinions

59, 61 will roll about their respective gears when the flyer is rotated,'but if the gear 58 is rotated, a corresponding rotation will be imparted to the gear 63 irrespective of Whether the flyer is being rotated or not. This mechanism pelanits the tying mechanism to be opera-ted without interfering with the operation of the flyer. j

When a skein has been wound to or approximately to the predetermined number of coils desired in each skein, it is removed froln the winding-position to a second position for the action of the knetter, the effect beingthat one skein after another may be wound upon the reel and tied or bound together without stopping the winding 'operation incident to the formation of the next succeeding skein. In Fig. 1 the winding position is indicated at W and the tying position at T. In the present instance of the invention this is accomplished by arms, Which may constitute a spider and which at proper times are moved to transfer the skein from the winding to the tying position. The spider which may bev indicated as a whole by 78, has a central hub portion 79 loosely mounted on the shaft 65 and provided with arms 82, and

collars

80 and 81, Fig. 12, cause longitudinal movement.l ot' the `shaft 65 to be imparted to the spider. The outer ends of the spider arms extend down- Ward and have heads formed thereupon, as

best shown in Figs. 14 and 15. These heads may be mounted to slide within slots 83 formed in the rails 9, 9B. The lower horizontal surface 84 of the heads are positioned to engage the -coils of filament wound upon the reel, and move them downward, when a downward movement is imparted to the spider. To insure that the strand will be positioned upon the reel below the surface 84, an inclined face 85 is preferably formed upon the heads to direct the coils downward to the proper position. The downwardly-directed ends 82 of the spider slidably mounted witharms. The shaft 35 is held at the desired height and raised and lowered as desired, by a bell crank lever 88 pivoted upon the frame at 89, one arm of the lever being connected to a collar 90 secured to the shaft The other arm of the lever 88 has a pin 91' extending into acam groove formed in the collar 92 secured to a sleeve 93 mounted upon and rotated by the shaft 54. The arrangement of parts is such that when the shaft 54 is rotated, the spider and flyer-.will be lowered for an interval and then raised and held in raised position.

The tying mechanism for tying the leading and trailing end of a skein may be generally described as consisting of a knot-tying head, and a filament-crossing head opposite the knot-tying head. The tying head 94, Figs. 6 and 26, is rotatably mounted within a wall'of the drum 7 and extends laterally a short distance from the drum, and is so positioned that it will lie directly back of the skein to be tied when lthe latter has been movedout of the normal winding position to the tying position. In performing the tyiner operation, it is necessary that the tying 2head be rotated, preferably about two complete revolutions; and this may be effected by a -segmental rack 95, Fig. 7, pivotally mounted at 96 to a wall of the drum. The rack meshes with a gear 97 mounted about the head. Motion is imparted to the rack by a crank arm 98 mounted upon the shaft 69, Fig. 6, and provided with a pin 99 entering a slot 100 in the segmental rack. `Whcn the shaft 69 is rotated a complete revolution, the knotting head will be rotated' in one direction the desired'extent, and then rotated in the opposite direction to original position. T he head 94 has a relatively large aperture formed therethrough, in which a tubular member 101 is slidably mounted, Fig. 28, and within which is arod 102 having a hook 103. The tubular member 101 is secured to a sliding bar 104 having a pin 105, Fig. 6, projecting into the cam slot 106 of the cam drum 72. The rod 102 is secured to a similar bar 107 having a pin 108, Fig. 6, projecting into the cam slot 109 of the drum, the construction being such that when the shaft 69 is rotated, the tubular member and rod will be moved through the knotter head by thc cam slots 106, 109, and

will cooperate with the head in forming the knol'. A pair of spaced hook members and 111 at opposite sides of the knotter head 94 operate to pull the strands to be tied toward the knotter head, and are rigidly secured to a crosshead 112 mounted upon a third slide bar 113 provided with a p in 114 projecting into a cam slot 115 of the drum, Fig. 6. As the hook member 111 moves inward, it draws the filament carried thereby across the blade of a knife 111L and cuts the same. as will be apparent from Figs. 25 and 26. The knotting mechanism is preferably enclosed in a casing 116 (see Fig. 9) and the casing has an ear 117 through which the hook member 110 reciprocates. 4

ln front of the tying head 94 is mounted a guide plate 118 positionedto support the parallel strands of the skein out of engagement with the head. This plate is provided with the

curved edges

119, 120, Figs. 25 and 26, which serve to guide the strands into a notch 121 in the plate 118 as they are pulled inward by the reciprocating hooks 110, 111. The plate may be conveniently supported by having one portion thereof 4secured to the casing 116 and a second portion secured to a rail 9a, as will be apparent from Figs. 9 and 25. An aperture 122 is formed through the plate 118 directly in front of the reciprocating rod 102 to receive the end of the rod when it is moved outwardly.

The knotter head 94 is provided with an engaging notch 123, Figs. 25 and 26, positioned to engage the filaments as the head is rotated. The filaments may be frictionally held in the notch by a finger 124 mounted upon a pin 125 and yieldingly held in engagement with the edge 126 of the notch by a spring 127.

Depending fromthe head frame. 2, Fig. 1, is a casing 128 in the' lower portion of which is rotatably mounted a shaft 129 carrying a crosshcad 130, which is positionedv opposite the knottying head 94. Mounted on the erosshead 130, Fig. 27, are the two crossing fingers 131, the outerA extremities of' which are formed as hooks 134. Adjacent the hooks 134 the crossing fingers are provided with filament-engaging springs 132 between which and the body of the fingers a filament may be held. The springs may be secured to the fingers by screws 133. The shaft 129 is normally held against rotation, and in such a position that the crosshead normally lies in the position shown in Fig. 2, so that one of the fingers 131 lies above the shaft 129 to one side of the vertical plane passing through the shaft. During the tying operation, the filament-crossing head is rotated through an angle of 180 so that the fingers 131 exchange places.

Mounted upon the sleeve 93 surrounding the shaft 54, is a disc 135, Figs. 1 and 5,

which o crates a second disc 136 secured to the s iaft 137, these discs constituting what may be termed a modified Geneva gear. The disc 135 in the present embodiment of the invention, is providedwith spaced annular ribs extending around the greater portion thereof to form the annular slot 138, and which receives a pair of pins 139 projecting laterally from the disc 136. The disc 135 is also provided with a laterally-projecting pin positioned to enter any one of three slots 141 formed in the face of the disc 136, the construction being such lthat the disc 136 is held against rotation until the disc 135 is rotated sufficiently to disengage the slot 138 from the pins 139, Whereupon t-he pin 140 will enter one of the slots 141 and rotate the disc 136 through an angle i of 120", in a well known manner. The shaft 137 is operatively connected to the shaft 129 by a sprocket chain 142 passing about a suita le gear upon each of these shafts.

The shaft 54 is to lbe periodically operated for the purpose of actuating the knotvter when a skein is to be tied, and a suitthe sprockets 143 and 145, and to this end,'

a pinion 147 is secured to the shaft 32, Fig. 3` and a similar plinion 148 is secured to the shaft 146. The pinion. 148 is driven by the p-inion 147 through the gear 149 loosely mounted on the shaft 150. The shaft 150, Fig. 16, is equally spaced between the

shafts

32 and 146, and has rigidly secured thereto the spaced heads or bars 151, 152. Each of these bars has notches 159 formed Ain the opposite ends thereof, and which are positioned to receive the opposite end of any one of the operating lugs or pins 160 carried by the chain -1.44. A drum 161 is mounted upon the: shaft and serves to hold the chain 144 away from the shaft a distance equal to the distance that the lug is held away from the shaft 150 by the notches 159,- the operation of the parts being such that since the

sprockets

143, 145 are driven at. the same rate of speed by the

pnions

147, 148, the chain 144 will be fed smoothly about the same; and when a portion of the chain carrying a pin 160 passes about the sprocket 145, the pin will enter the notches 159 and rotate the spaced heads 151, 152 and the shaft 150, te which they zfknotche's;y The chain 144 may be given any are secured. ln the articular` construction shown, the sha t will be rotated through 180, as the pin will be retained in the notches 159 until it passes about the second sprocket 143. The mechanism just described provides a satisfactory intermittent feed, since, 'as will be apparent from Fig. 16, the pin enters the notch `159 when this notch lies substantially tangential to the sprocket 145, so that the starting motion is gradually and smoothly apphed to the heads 151 and. 152, while the pin is moved within the notches, after which the heads will `be rotated more rapidly. In a similar manner, the rotation of the head is slowed down as the pin passes about the other.- sprocket-wheel 143 and ont of the l"desired length, and the pins 160 are positioned at such intervals that they will actuate the knotter when a predetermined number of coils have been wound to form the skein. If desired, the machine frame may have secured thereto a guide rail 162, Figs'. 1 Iand 16, in which a floating roller 163 is slidably supported, the roller being lpositioned to lie in the loop formed in the vided with a pin 168 to normally engage the recess 166. The arm 167 is mounted on \a fixed pin 169, and may be normally held in en agement with the recess 166 by a spring 1 0. T'he movement of the arm by the spring may be limited by providing a fixed pin 171 against which a portion 172 of the arm bears. The pin 168 is so constructed that as the lug 160 upon the chain moves into the notches 159, it will force the pin 168 out of its recess 166 and thus release the heads so that they may be rotated.

As will be late-r explained, when enough coils have been placed about the reel to form a skein of the desired number of coils, the portion of the filament which is being wound' at that instant is used to bind up the skein just completed, and to provide slack for this purpose, means is provided Ifor dra-wing forward through the flyer a sutlicient amount of the filament being wound. In) the present instance, an arm 173, Figs. 1 and 10, is secured tothe lower end of the downwardly-extending shaft 174 rotatably mounted in a bearing 175 in the machine head 2. The arm 173 is provided with a finger 176 which is swung from the position shown in -full lines in Fig. 10 to that indicated by dotted lines, to produce the desired slack in the filament. Rocking motion is imparted to the shaft 174 from the c am slot in the collar 92, previously described. The upper end of the shaft 174 11s, provided with a crank arm 177 connected to a bell crank lever 178 pivotally mounted at 179. One end of the bell crank lever is connected to the crank arm 17 7 by a link 180, while the other end is provided with a pin 181 operatively engaging the cam slot in the collar 92.

As above pointed out, the coils wound about the reel are to be moved from the normal windin position indicated by the arrow `W in 4ig. 1, to the position indicated by the arrow T when the knot is to be tied, and this is accomplished by lowering the spider 79. After the coils have been moved to the tying position indicated by the arrow T and the skein has been tied, the tied skein is to be moved further along the reel toward the point of delivery. The pnshers 86 above mentioned as being pivotally secured to the spider arms and mounted within the fixed rails 9, Fig. 14, are constructed so that the lower end normally projects beyond the edge of the rail 9, Figs. 1 and 14, but are free to swing inwardly to pass by a skein as the pusher is carried npwardly by an upward movement of the spider. The rails 9, 9a are cnt away below the shoulder 182 so that the diameter of the reel below the shoulder is less than above it, and the pushers 86 are preferably so positioned that they will push thc skein below the shoulder. After the skein is moved below this shoulder it will either fall by gravity upon the table 1, or may be easily moved down by hand.

The drum 7 and rcel are supported in a manner so that the completed skeins may be removed from the machine during and without interrupting the winding operation. In

the present instance, two sets of pins snpport the drum and reel, and are so arranged that they may be alternately moved into' and out of supporting position to permit the skeins to pass. In the present embodiment, six pins 183 are slidably mounted within the table 1, and are arranged below the drum 7. The pins are preferably provided with pointed ends 184 adapted to be received in sockets 185 in the lower face of the drum and are held in engagement with the drum to support the saine, by the cam 186 having cam notches 187, Figs. l, 2 and 24. Thel cam may be mounted upon a vertical shaft 188 supported by the bridge 5, which is provided with lugs 189 which en lgage the under face of the cam to support and steady it. The notches 187 are so positioned that after one set of pins has been forced into supporting engagement with the drum, the other set of pins will be permitted to drop from their supporting position. To this end the notches 187 are provided with a sloping Wall 190 and a vertical wall 191, the construction being such that when the cam is rotated, one set of pins will be moved into and the other set of pins will be moved out of supporting position to permit the skeins 193, Figs. 22 and 23, to be removed.

.desired amount.

Connected to the cam 186 is the hub portion 197 provided with ratchet teeth adapted to be engaged by a pawl 195 carried at 196 on a swinging member or ,pawl carrier 194 mounted loosely on the shaft 188. The pawl may be actuated from time to time by any suitable means, as, for instance, the chain 198 which may be connected to an arm 199 extending from the pawl carrier and actuated in one direction by a treadle 200 and in the opposite direction by a spring 201 connected to the machine frame at 202.

The present invent-ion contemplates that the winding and tying of one skein after another may continue uninterruptedly until a predetermined number of wound and tied skeins have been produced, and that then the machine Will be automatically stopped. To this end a ratchet wheel 203, Figs. 1, 3 and 29, is provided with a stub shaft 204 supported by a bracket 205 upon the head 2 of the machine. One face of this ratchet wheel is provided with a cam lug 206 positioned to be moved into operating engagement with a sliding pin 207 having an end engaging the clutch-releasing rod 49. Then the ratchet Wheel is rotated sufficiently to bring the lug 206 into operating engagement with the pin 207, the rod 49 will be moved to the left of Fig. 3 sufficiently to release the rod 21 from its catch 23. The ratchet Wheel is rotated toward the machine stopping positioh a desired increment each time the shaft 150 is rotated to operate the tying mechanism, and in the present instance of the invention, the shaft 150 is provided with two

eccentrics

208, 209, having pawls 210, 211- operated thereby, the ends of these pawls being positioned to operatively engage the notches in the ratchet Wheel 203, Fig. 29.

Two pawls are provided because the shaft.

150 which operates them, rotates only 180 each time the tying mechanism is actuated to tie a completed skein. The ratchet Wheel 203 may be set in any one of a number of positions depending upon the number of skeins to be formed before the machine is stopped, and the positions may be conveniently determined by forming a number of pin-receiving apertures 212 in a face of the ratchet Wheel, adapted to have a pin 213 inserted in any one of them, the pins being positioned to strike against a stop 214 when the Wheel has been rotated backward the After the ratchet Wheel has been operated by the pawls to stop the machine, it may be returned to its starting position b a spring about the shaft 204 which wil rotate the ratchet wheel to the position shown in Fig. 29, or 'starting position, as soon as the awls have been disengaged from the rate et by the hand-operated lever 215.

In operating the machine, before it is started, the filament is led from the flyer to the lower finger of the filament-crossing head, and is secured thereto by the filamentgripping spring upon the finger. The machine is then started and the fiyer rotates about the fixed reel to lay the filament upon the reel in the normal Winding position. As the flyer travels about the reel to lay the last coil of a skein, the fiyer and spider are lowered to move the practically completed skein from the normal winding position to the tying position, and as the flyer completes the laying of the last coil, it is raised sufficiently to clear the upper finger of the crossing head, but not enough to cause the filament to clear the hook upon this finger, with the result that the fila-ment is placed in engagement with the finger. Thereupon, the crossing head is rotated to cross the leading and trailing ends of the skein over the skeinand in front ofthe tying head, while the fiyer operates to wind a new skein. As the crossing head is rotated, the filament placed about the upper finger is pulled under the spring upon the finger and is frictionally held thereby. The rotation of tbe crossing head carries the ends of the skein into engagement with the reciprocating hook upon the opposite sides of the knot-tying head, and these hooks operate to pull the ends into position to be engaged by the knot-tying head, whereupon the head is rotated to form a loop in the ends to be tied and a reciprocating hook within the knot-tying head pulls the ends through this loop and forms the knot. After the 'knot is tied, the parts of the knot-tying head are iestored to their normal position, ready to tie the next knot when again operated.
