- the nut I68 on the bolt IE1 is loosened and the bracket I58 moved toward the right, as viewed in Fig. 2,'with the shaft I55 sliding in the slot I65 in the standard I50.
- the bracket I58 then may be rockedupwardly to carry the worm I64 into alinement with the worm-wheel 51, after which the bracket may be shifted toward the left to engage the worm with th teeth on the worm-wheel.
- the nut IE8 With the worm I55 engaged with the worm-wheel 31 the nut IE8 is tightened on the bolt I51 to clamp the bracket I58 in its adjusted position.
- the worm-wheel 41 may be rotated from the worm I65 in the same direction as that in which it is driven by the worm I62 when the direction of rotation of the countershaft is reversed by reversing the motor I313.
- the purpose of this arrangement is to provide that the spindle-carrier 50 will always turn in the same direction even though the winding spindles are driven in reverse direction in some nstances for the purpose hereinafter explained.
- the spindles II! are rotated by means of the pulleys 5-3 keyed to their lower ends.
- the pulleys 43 are rotated by means of an endless belt I10 encircling the series and driven by a flanged pulley I1I at the upper end of the countershaft I22, see Figs. 2 and 3.
- the belt I is maintained under tension by means of an idler pulley I13 journaled at the end of an arm I14 fastened to the upper end of a bushing I15 surrounding the countershaft I22 and projecting upwardly from the bearing I36 on the standard I31.
- the arm I14 has a split hub I15 surrounding the bushing I15 with a binder-screw I11 therein for clamping the arm in position to maintain the idler pulley I13 pressing against the slack side of the belt I10.
- the traverse-cam I05 is rotated at a relatively fast rate of speed during the travel of the winding spindles All and the cores I) mounted thereon around its circumference, the cam'being driven by its shaft H5 carrying the stepped pulley II5 previously referred to.
- the pulley H5 is connected by the belt II8 to a smaller pulley I69 on the lower end of the countershaft I22, this latter pulley having stepped faces arranged opposite to the stepped faces on the pulley H5 so that by shifting the belt II8 thereon the speed of rotation of the cam I05 may be varied to alter the character of the wind in accordance with different materials being wound.
- a handle I82 on the outer end of the shaft I8I provides a convenient means for rocking the belt-shipper to shift the belt II8 on the pulleys I I5 and IE3.
- the complete bobbin-winding machine having been described in detail its method of operation is as next explained:
- several determining factor are first ascertained and the operating elements adjusted in accordance with requirements. For example, the required number of turns or coils of yarn to be deposited on the bobbins during each traverse stroke is determined.
- the speed of the spindles is constant and therefore to secure the correct ratio between the rotative speed of the bobbins and the traversing rate of the yarn to produce bobbins having a definite character of wind, the belt II 8 for driv in the traverse-cam I85 may be shifted on the stepped faces of the pulleys H5 and I65 in accordance with requirements.
- the belt I I8 is positioned to pass around the pulleys H5 and I 69 in the manner shown in Fig. 2 of the drawings to provide a fourteen-to-one ratio between the rotative speed of the spindle 40 and the speed of the traversecam I55. With this latter arrangement the bobbins will be wound with what is termed a seven Wind.
- the ratio between the rotative speed of the bobbin-spindles 40 and the traverse-cam I55 should be ten-to-one and to obtain this relationship the belt H8 may be shifted onto the opposite faces of the pulleys H5 and I69.
- Another factor to be considered in preparing the machine for operation is whether the bobbins are to be wound with a regular or reverse wind in accordance with the type of twist in the yarn.
- bobbins For producing bobbins with a regular wind they are rotated in clockwise direction so that when the yarn is subsequently drawn off over the end it will unwind in clockwise direction.
- it is sometimes desirable to produce a reverse wind by rotating the bobbins in counterclockwise direction to provide that when the yarn is drawn off over the end it will unwind in counterclockwise direction.
- a switch in its circuit may be used to control the direction of rotation of its armature whereby to adjust the machine for producing either regular or reverse-wound bobbins.
- the motor I30 drives the countershaft I22 and through the connections described above -the spindles 40 will be rotated on their own axes at relatively high speed and revolved at a slow rate about the axis of the track 20 whilethe traversecam I05 is rotated ata speed in proper ratio with that of the spindles.
- an empty spindle 40 has reached the position shown at F in Fig. 10 with its roller traveling up the-sharp incline I28 and onto the elevated rest I25 of the spindle.
- the head 11, of a
- bare bobbin-core 1)- next may be placed in the recess 42 of the spindle head ll to clamp the yarn between it and the head while the tip of the core is inserted in the recess in the head 70 of the stub-spindle 75 :as shown at the right in Fig. 2 and indicated at C in Fig. 10.
- the spindle 40 will have been elevated by the engagement of the roller 65 on the bearing sleeve 53 with the high point or rest I25 of the track 20 and thus the yarn leading from the guide 10b to the head h of the bobbin will be restrained from contact with the edge of the rotating traversecam I05. Referring to Fig.
- the central column or standard comprising the vertical rod 80 is rotated slowly with the spindle-carrier 50 to which the rods are attached so that the supplypackages P mounted. at the upper end of the column will revolvetherewith. 7
- the supply of .yarn inflone package P is exhausted the connected strand delivering from anew package arranged below. or above as the case may be,.will feed downwardly to the bobbin B being wound.
- a fresh supply-package P then may be substituted. for the empty cone-tube or other yarn-carrier and the leading end of its strand tied to the trailing end of the yarn in the package from which the yarn is delivering. In this manner the supply'of yarn is maintained continuous with the result that the winding operation may proceed without interruption.
- spindle-carrier 55 must always rotate in counterclockwise direction, as viewed in Fig. 4, to insure thatthe rollers 65 will travel in the proper directionon the track 20.
- the nut 58 on'the bolt It! is loosened and the bracket 53 rocked about the shafts l5! and I55 to mesh the worm 164 with theworm-wheel 41 on the spindle-carrier 59, after which the nut is tightened to hold the bracket in adjusted position.
- gear I 56 With the various parts adjusted in this manner the gear I 56 will be driven in the opposite direction from that first described to drive it companion gear [51 in reversedirection and turn the worm I64 to rotate the carrier 50 in counterclockwise direction to effect proper co operation between the rollers 65 and track 20.
- the sloping raceway I21 of the track 20 maybe formed with a profile. of greater or lesser inclination for different. lengths of bobbins or its cam-face maybe variedin other ways as required for different types of packages, all within the scope and purview of the present. invention.
- the present invention provides a bobbin-windingmaohine which is of simple, compact construction While being highlyefflcient. inoporation.
- the present machine comprising a plurality of winding spindles arranged to travel about the centrally-located cam, common to all the spindles, the traversing means is reduced to utmost simplicity, thereby eliminating the. usual reciprocating yarn-guides and other parts liable to. wear and deterioration in use.
- the meansfor advancingthe traverse of the yarn lengthwise of the bobbins is common to all of the several winding spindles and avoids the use of screw-threaded progression wheels, ratchet-devices and other complicated mechanisms.
- the present improved machine provides for winding a plurality of bobbins continuously at high speed by the use of extremely simple mechanism while requiring little attention on the-part of the operator. 7

This invention relates to improvements in winding machines and particularly to machines for winding yarn into cops, pirns and bobbins for use in the shuttles of looms or packages for other purposes.
It is to be understood that the term yarn as used in the present specification and claims is intended to apply to all types of attenuated materials, whether textile or otherwise, and the term bobbin is employed in a broad sense to mean any type of wound package.
One object of the present invention is to provide a winding machine of the type indicated which is of simple, compact construction having relatively few moving parts.
21 Claims. (Cl. 24232) Another object of the invention is to provide a machine of the type indicated in which the yarn is traversed on the cops or bobbins without the use of reciprocating elements liable to wear and deterioration under high speed operation.
Another object of the invention is to provide a machine of the type indicated having means for traveling the bobbins in a closed course, winding as they go, to successively bring them to a station for dotting the completed bobbins and replacing them with fresh cores or yarn-carriers to commence winding again.
Another object of the invention is to provide a winding machine of the type indicated comprising a rotary cam acting directly on a plurality of yarns to traverse them on the bobbins, means for traveling the bobbins in a closed course and means for progressively advancing the traverse during the travel of the bobbins.
Another object of the invention is to provide a machine of the type indicated which may be operated at high speed to increase its rate of production while at the same time requiring little attention on the part of the operator except to piece up broken ends and replace the supplies as they become exhausted.
Further objects of the improvement are set forth in the following specification which describe one preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings. In the drawings:

Fig. 10 is an enlarged schematic view showing a development of the profile of the cam-track or inclined raceway for shifting the winding spindles in axial direction as they travel therearound to advance the traverse of the yarn lengthwise of the bobbins and indicating the position of one bobbin arriving at the dofiing and donning station where each spindle is supplied with a fresh core or yarn-carrier.
In general, the present improved winding machine comprises a closed track, preferably of cylindrical form, having an inclined raceway around which the bobbins travel, winding as they go, with the cores or yarn-carriers mounted on vertical spindles which are rotated continuously A traverse-cam positioned concentrically within the circular track or raceway and rotated continuously from the machine driving means is arranged with the plurality of yarns feeding across its helical face to cause the strands to be traversed to a relatively short extent. The zone of traverse is advanced progressively longitudinally of the bobbins to form nested conical layers producing a cylindrical body of yarn with tapered or conical ends. As the winding spindle travel around the inclined circular track they are lowered pro gressively to cause the layers of yarn to advance upwardly along the cores, and eventually, as each bobbin is completed, it arrives at a station for doifing it from its spindle and donning an empty core. The donning and doffing operations may be performed manually but, preferably, suitable automatically-operating means, not herein shown, are provided for this purpose.
As herein shown, the machine is provided with eight winding spindles for mounting the cores or yarn-carriers on which the bobbins are wound, but this number is arbitrary and a greater or lesser number may be employed. The supplycops or packages are arranged above the winding spindles in two groups supported one above the other in annular disposition about a central standard; the supply-packages preferably being magazined with the last delivering end from one package united to the first delivering end of a companion supply so that the yarn will deliver continuously first from one package and then from another and the exhausted supplies may be replaced with full packages without arresting the winding operation. The yarns from the supplies volve therewith within the track 20. The car- .therein. Each sleeve 58 is provided with a re- "duced bore at its upper end with a bushing 59 feed through suitable tension-devices mounted thereabove and thence lead through guide-eyes and a guiding ring to direct them downwardly to another set of guide-eyes within the traverse-' cam and then laterally across its edge to the winding bobbins.
Referring to Figs. 1 and 2 of the drawings, the present bobbin-winding machine'may comprise a hollow rectangular bed or. base 2 resting on the floor or upon suitable standards, not shown, and surmounted by a hollow box-like housing 3. As shown in Figs. 2 and 3, the housing 3 may be fastened to the top wall 4 of the bed 2 by means of bolts 5 passing through ears 6 on the housing and screwed into threaded holes in the base. The housing 3 encloses the driving mechanism of the machine and is provided' on itsside with; an opening I, see j Fig'.j 3,
for permitting access thereto. The opening ,1
may be covered by a door 9 hinged to the side i of the housing 3, see Fig. l, and normally-held closed by means of a hand-latch l4 engageable with a lug l5 on the side of the housing.
A circular opening I8 is provided in the top wall of the housing 3 adjacent one end thereof, see Fig. 2. The opening I 8 is .counterbored to form a circular ledge l-9 upon which is seated the lower end of a cylindrical track or raceway 20 formed with an upper cam-like rim, described later in detail. As shown in Fig. 2, the track 20 may be secured in place on the casing 3 by means of screws 21 passing through holes in the flange surrounding the ledge I9 and screwed into threaded holes in'the sides or the track.
Fastened to the top wall l of the base 2 by means of screws 24 and extending upwardly therefrom in concentric relation to the opening l8 in the housing 3 is a hollow column or standard 25. As shown in Fig. 2, the upper portion of the standard 25 is reduced in diameter to receive the hub 29 of a rotatable member 35, a bushing 3! being employed in the bearing between these parts to reduce wear. Themember 3!] is provided at its lower end with apair of circumferential flanges 33 and 34 which are bored at spaced intervals to provide bearing openings 35 and 36 extending in parallel relation to the axis of the member. The openings 35 and 36 may be provided with bushings 38 for mounting the vertical winding spindles All of the machine, described in detail hereinafter, which are adapted 'to rotate and slide vertically therein. Fastened to the lower flange 34 of the member 30 by means of screws 46 is a worm-gear 41 provided with teeth on its periphery, see Figs. 2 and 3.
Mounted upon the upper end of the member 30 is a rotary member or carrie'r50 for supporting the plurality of vertical winding spindles 40, see Figs. 2 and 4, which are adapted to retherein for rotatably supporting the upper end of a winding spindle 40. Each spindle All is provided'with an enlarged head '4! seating upon the upper end of the bushing 59. A cup-like recess or depression 42 in each head 4! is adapted to receive the enlarged butt h of a wooden bobbin 1) for rotating the latter in the manner and for the purpose as explained hereinafterh The lower portion of each spindle ii is journaled in the alined bushings 33 in the bores of the flanges 33 and 34 of the member 35, previously referred to, and mounted on each spindle is a small pulley 43 positioned between the flanges. As shown in Figs. 2 and 3, the spindles do are formed with relatively long keyways 45 and the pulleys 43 have keys 44 engaging therein to rotatively connect them therewith while permitting the spindles to slide vertically in their bearings. Fastened to the side of each sleeve 58 by means of screwstZ is a key 6.3 which projects outwardly through the vertical slot 56 in the side of the cylinder 55 to restrain thesleeve from rotation while permitting it to slide axially therein. A headed stud 64 having a reduced threaded shank screwed into a tapped hole in the key 63 on each sleeve 58 carries a roller 55 journaled thereon and arranged to rest upon and roll along the upper cam-edge of the track 20, see Figs; 2 and 10.
. A rod 68 attached to the key 63 on each sleeve 58 by screws 69 extends upwardly for mounting an 'arm l8. As shown in Figs. 2 and 5, each arm i8 i formed with a split hub H which is adjustably clamped to the rod 68 by means of binder-screws 12. Each arm 10. terminates in a cylindrical boss 73 provided with a bore 1 axially alined with its registering spindle 40 and rotatable in the bore is a stub-spindle 15. As shown at the left in Fig. 2, the stub-spindle 15 carries a head 16 at its lower end which is recessed to receive the tip end of a core or wooden bobbin 1). The stub-spindle 15 normally is urged downwardly to engage the tip end of the wooden bobbin b in the head'lfi by means of a helical spring ll surrounding the spindle with its ends abutting the head 15 and the under side of the boss 13. Downward movement of the stubspindle I5 is limited by the engagement of a washer l8, fastened to its upper end by a screw I9, with the upper end of the boss 13. It will be understood from the foregoing description that the several winding cores or wooden bobbins b are held between the heads 4! of the winding spindles 40 and the heads or cups 16 on the stubspindles l5 so that when the spindles 50 are rotated through driving means, described later. the bobbins likewise will be rotated at relatively high speed.
The yarns y are supplied to the winding bobbins from a magazine creel arranged above the winding mechanism and supported on a skeleton column or framework comprising a plurality of v vertical rods 80 rising from the spindle-carrier 50. Mounted on the rods 80 are two circular shelves or brackets 8| and 82, the upper one of which is shown in plan view in Fig. 6. The bracket BI preferably is of skeleton form having spokes radiating from a central ring 83 for supporting itsouter rim which is provided with a series of supply-holders comprising disks 84 with suitable spindles 85 rising from the axes thereof. The supply-packages P may be in'the form of crosswound cones of large bulk which are seated on the spindles 85 with their bases restin on the disks 84. As shown in Fig. 6, the edge of the rim of the bracket 8| is formed with recessed guide-eyes 86 for the trailing ends of the yarns from the upper sets of supplies P to direct them downwardly for connection to the leading ends of the supply-packages P of the lower set.
Mounted on the upper ends of the vertical rods 80 is a circular plate 81, to which are attached a plurality of tension-devices 88, equal in number to the number of supply-packages in each series. The tension-devices 88 may be of any usual construction; for example, of the grid-type as shown in Fig. 1, and associated therewith are lower and upper guides 89 and 90 for directing the yarns from the supplies P between the tension-grids. Supported above the plate 81 is a bracket 9| on which are mounted a series of resilient arms 92 which radiate therefrom and carry pigtail or round thread-guides 93 at their ends. The guides 93 are adapted to receive the yarns leading from the tension-devices 88 to direct them downwardly to a series of Pigtail-guides 94 projecting from the rim of the upper bracket 8!. From the pigtails 94 the yarns are arranged to feed downwardly through a gathering ring 95. The gathering ring 95 is mounted on the rods 80 b means of bosses 96 and is formed at its center with an axial hub 91. Held in the axial hub 91 is a depending vertical rod 38 mounting a hub or boss 99 at its lower end. The hub 99 supports a series of radially-projecting pigtail-guide I by means of which the yarns y are adapted to be guided to the spindles 40 to wind'on the cores or wooden bobbins b. The supply-packages P of the lower series are mounted on supply-holders similar to those previously described carried onthe bracket 82 and the leading'ends of the yarns y therefrom are fastened to the trailing ends 11 from the packages P of the upper set so that the yarns may deliver continuously first from the upper supplies and then from the lower supplies, and vice versa, while exhausted supplies are being replaced by full packages. The complete assembly of the creel and yarn-guiding means described above is thus carried on the column comprising the rods 00 which are supported from the spindle-carrier 50 to rotate therewith as the winding bobbins b travel around the trackway 20.
In winding filling bobbins for use in the shuttles of looms and for some other kinds of packages, the yarn is distributed on the cores or yarncarriers with a relativel short traverse and the zone of traverse advanced progressively from the base to the tip end of each core. In the present machine the yarn is distributed on the core or wooden bobbin b with an extent of traverse considerably less than the length of the bobbin by means of a rotary cam I05, shown in detail in Fig. '7. The cam I is of dish-shape as constituted by a circular bottom wall I06 and a cy-' lindrical rim I01, the upper edge of which is of helical contour'or profile. As shown in Fig, 2, the bottom wall I 05 of the traverse-cam I05 is fastened by screws I08 to a disk I09 fast on the upper end of a vertical shaft I Ill. The upper end of the cam-shaft H0 is journaled in a bearing III mounted at the upper end of a tubular support H2. The lower end of the tube H2 is fitted to the reduced upper terminal portion of the stationary standard 25. The lower end of the camshaft IIO is journaled in a bearin II3 formed in 7 the top wall 4 of the bas 2. The cam-shaft H0 projects downwardly below'the bearing H3 and carries a stepped-face pulley II5 which is keyed thereto and held axially thereon by a set-screw III. The shaft H0 may be driven continuously by a belt I I8 or by gearing connected to the main driving mechanism of the machine described hereinafter.
During th winding operation the bobbins are gradually lowered with respect to the traversecam I05 so that the zone of traverse will be shifted progressivel toward the tip of the cores b to eventually produce bobbins B of the shape shown at the left in Figs. 2 and 10. This gradual lowering of the bobbins is effected by revolving the spindles 40 around the track 20 with the ro1.- lers 65 on the sleeves 58 riding on its inclined raceway. Fig. 10 illustrates a development of the track 20 and indicates the manner in which the rollers 65 ride along its upper cam-shaped rim. As shown in this latter view, the upper beveled edge of the track 20 is formed with a short horizontal rest I and a sharply-inclined portion I26 Which slopes downwardly therefrom to merge into a raceway I21 of lesser inclination. The raceway I2! extends throughout substantiall five-sevenths of the entire circumference of the track 20 and then merges into an upwardly-inclined portion I28 which connects with the rest I25. At the start of the winding operation the roller 65 for the spindle 40 of each bobbin 1) will ride off from the rest I 25, travel down the sharply-inclined portion I 26 and onto the gradually inclined raceway I21, at which point the winding is commenced. As the bobbins revolvein a path concentric to the axis of the cam-shaft IIO the roller 65 on the sleeve 58 carrying the spindle 40 for each bobbinwill ride downwardly along the raceway I21 of the track 20 to cause the bobbin to be gradually lowered whereby to advance the zone oftraverse of the yarn upward on the core b.
The driving mechanism for the machine is enclosed in the housing 3 and may comprise a prime-mover such as a reversible electric motor I30 shown at the right in Figs. 2 and 3. A pulley I3I on the shaft of the motor I30 may be connected to drive a vertical countershaft I22 by means of a belt I33 passing over a pulley I34 on the countershaft. The countershaft I22 is journaled in a lower bearing I35 formed in the top wall 4 of the base 2 with its upper end supported in a bearing I36 projecting laterally from a standard or bracket I31 bolted to the base of the machine at I38. The countershaft I22 is connected to drive the rotary spindle-carrier 50 through a train of gearing driven from a worm I39 keyed to the countershaft. The train of gearing is mounted on a bracket or standard I40 bolted to the top of the base 2 and carrying suitable bearings for the shafts of the gears. The worm I39 meshes with a gear I4I carrying a pinion I42 fast on its shaft I43 and meshing with a larger gear I44 fast on a shaft I45. The shaft I45 carries a pinion I 46 meshing with a larger gear I 41 fast on a shaft I48. Keyed to the shaft I48 is a gear I49 meshing with a larger gear I50 fast on a shaft I5I. The shaft I5I carries a pinion I53 meshing with a gear I54 fast on a shaft I55. The gear I54 drives through a pair of change-gears I55 or I51, the shafts of which are mounted in an adjustable bracket I58 pivoted to rock about the shaft I55. The gear I55 is mounted fast on a shaft I69 iournaled in the bracket I58 and carrying a worm I62. The worm IE2 is adapted to mesh with the worm-wheel 41, previously described as being fastened to the member 35 which mounts the spindle-carrier 50 for rotation therewith. l
Th change gear I51, previously mentioned, has its stud-shaft I63 rotatably mounted in the bracket I58 and fast on the inner end of the shaft is a worm IE4. The shaft I55 is adjustably mounted in an arcuate slot I 65 provided in the upper end of the standard MI) in concentric relation to the axis of the shaft I5I. The bracket I58 is also provided with an arcuate slot I55 concentric to the axis of the shaft I55. A bolt I51 extends through both slots I65 and I 65 and a nut I58 screwed onto the threaded end of the bolt is adapted to clamp the bracket I58 in different positions of adjustment, see Figs. 2 and 3. With the bracket I55 in the position illustrated in Fig. '2, the gear I51 rotates as an idler during the drive through the gear I55 and worm I62 to the wormwheel 41. In other instances, however, the gear I51 maybe shifted into position to adapt the worm I64 fast on its shaft I63 to drive the wormwheel 51, whereupon the worm I52 will be disengaged from the worm-wheel 41. To effect this change in the drive the nut I68 on the bolt IE1 is loosened and the bracket I58 moved toward the right, as viewed in Fig. 2,'with the shaft I55 sliding in the slot I65 in the standard I50. The bracket I58 then may be rockedupwardly to carry the worm I64 into alinement with the worm-wheel 51, after which the bracket may be shifted toward the left to engage the worm with th teeth on the worm-wheel. With the worm I55 engaged with the worm-wheel 31 the nut IE8 is tightened on the bolt I51 to clamp the bracket I58 in its adjusted position. In this latter position of adjustment the worm-wheel 41 may be rotated from the worm I65 in the same direction as that in which it is driven by the worm I62 when the direction of rotation of the countershaft is reversed by reversing the motor I313. The purpose of this arrangement is to provide that the spindle-carrier 50 will always turn in the same direction even though the winding spindles are driven in reverse direction in some nstances for the purpose hereinafter explained.
As the spindle-carrier 55 is rotated to revolve the bobbins about its axis, thereby traveling them around the trackway 2B, the spindles II! are rotated by means of the pulleys 5-3 keyed to their lower ends. The pulleys 43 are rotated by means of an endless belt I10 encircling the series and driven by a flanged pulley I1I at the upper end of the countershaft I22, see Figs. 2 and 3. The belt I is maintained under tension by means of an idler pulley I13 journaled at the end of an arm I14 fastened to the upper end of a bushing I15 surrounding the countershaft I22 and projecting upwardly from the bearing I36 on the standard I31. The arm I14 has a split hub I15 surrounding the bushing I15 with a binder-screw I11 therein for clamping the arm in position to maintain the idler pulley I13 pressing against the slack side of the belt I10.
The traverse-cam I05 is rotated at a relatively fast rate of speed during the travel of the winding spindles All and the cores I) mounted thereon around its circumference, the cam'being driven by its shaft H5 carrying the stepped pulley II5 previously referred to. The pulley H5 is connected by the belt II8 to a smaller pulley I69 on the lower end of the countershaft I22, this latter pulley having stepped faces arranged opposite to the stepped faces on the pulley H5 so that by shifting the belt II8 thereon the speed of rotation of the cam I05 may be varied to alter the character of the wind in accordance with different materials being wound. A forked belt-shipper I within the confines of the bed 2, see Fig. 1, is pivoted to its forward side by means of a rod or shaft IBI. A handle I82 on the outer end of the shaft I8I provides a convenient means for rocking the belt-shipper to shift the belt II8 on the pulleys I I5 and IE3.
The complete bobbin-winding machine having been described in detail its method of operation is as next explained: In preparing the machine for operation several determining factor are first ascertained and the operating elements adjusted in accordance with requirements. For example, the required number of turns or coils of yarn to be deposited on the bobbins during each traverse stroke is determined. In the present ma chine the speed of the spindles is constant and therefore to secure the correct ratio between the rotative speed of the bobbins and the traversing rate of the yarn to produce bobbins having a definite character of wind, the belt II 8 for driv in the traverse-cam I85 may be shifted on the stepped faces of the pulleys H5 and I65 in accordance with requirements. Assuming that it is required to deposit seven coils or turns of yarn on each bobbin during each traverse stroke in either direction, the belt I I8 is positioned to pass around the pulleys H5 and I 69 in the manner shown in Fig. 2 of the drawings to provide a fourteen-to-one ratio between the rotative speed of the spindle 40 and the speed of the traversecam I55. With this latter arrangement the bobbins will be wound with what is termed a seven Wind. For producing bobbins having a five wind, as is sometimes desirable, the ratio between the rotative speed of the bobbin-spindles 40 and the traverse-cam I55 should be ten-to-one and to obtain this relationship the belt H8 may be shifted onto the opposite faces of the pulleys H5 and I69.
Another factor to be considered in preparing the machine for operation is whether the bobbins are to be wound with a regular or reverse wind in accordance with the type of twist in the yarn. For producing bobbins with a regular wind they are rotated in clockwise direction so that when the yarn is subsequently drawn off over the end it will unwind in clockwise direction. On the other hand, it is sometimes desirable to produce a reverse wind by rotating the bobbins in counterclockwise direction to provide that when the yarn is drawn off over the end it will unwind in counterclockwise direction. With a standard threephase A. C. motor of squirrel-cage type a switch in its circuit may be used to control the direction of rotation of its armature whereby to adjust the machine for producing either regular or reverse-wound bobbins. For the purpose of illustration let it be assumed that a regular wind is desired and that the armature of the motor I30 is rotated in counterclockwise direction as viewed in Fig. 2, to cause the spindles 48 to rotate in clockwise direction as viewed in Fig. 8.
With the armature-shaft of the electric motor I30 rotating in counterclockwise direction and with the worm I62 in mesh with the worm-wheel in Fig. 3 whereby to slowly travel the spindles 40 in an annular course with their rollers 65 rolling on the upper face of the stationarytrack 20. At the start of a winding operation the cores or wooden bobbins b are applied to-the spindles 40 and the yarn-strands y attached thereto as they arrive at the donning station in regular sequence. The motor I30 drives the countershaft I22 and through the connections described above -the spindles 40 will be rotated on their own axes at relatively high speed and revolved at a slow rate about the axis of the track 20 whilethe traversecam I05 is rotated ata speed in proper ratio with that of the spindles. Assuming that an empty spindle 40 has reached the position shown at F in Fig. 10 with its roller traveling up the-sharp incline I28 and onto the elevated rest I25 of the spindle. The head 11, of a. bare bobbin-core 1)- next may be placed in the recess 42 of the spindle head ll to clamp the yarn between it and the head while the tip of the core is inserted in the recess in the head 70 of the stub-spindle 75 :as shown at the right in Fig. 2 and indicated at C in Fig. 10. During this donning operation the spindle 40 will have been elevated by the engagement of the roller 65 on the bearing sleeve 53 with the high point or rest I25 of the track 20 and thus the yarn leading from the guide 10b to the head h of the bobbin will be restrained from contact with the edge of the rotating traversecam I05. Referring to Fig. 8, during the short interval that the spindle is elevatedtoward the rest I25 on the track 20 it is displaced away from the driving belt I10 and therefore will not be rotated therebyl As the spindle-carrier 50 continues'to rotate slowly in counterclockwise direction, as viewed in Fig. 8, to convey the core b to the-station represented by the reference character D in Figs. 8 and 10 the roller 65 will travel down the inclined portion I26 of the track 20 I and onto the less inclined raceway I21 thereof.
As the core I) approaches the position indicated at D in Fig. 10 the pulley 43 at the lower end of the spindle 40 will be carried into the path of the driving belt I10 to be engaged and rotated thereby. As the spindle 40 and core b mounted thereon are rotated the yarn y will be caused to wind on the core and since the yarn feeds across the edge of the rotating traverse-cam I05 it will be traversed back andforth lengthwise of the core with an extent of traverse equal to the rise and fall of the cam-face. a
During the travel of the first bobbin from the donning position indicated at C tothe initial winding position represented at D in Figs. 8 and 10 another spindle will have been advanced to the station C to receive a bare bobbin-core b. This core b is applied between the heads ll and I6 0f the spindle 40 and stub-spindle "I5, respectively, and another yam-strand 11 attached thereto in the manner explained above in connection with the first bobbin considered. s the winding operation progresses, the operator of themachine may continueto1 place empty cores 1) on the successive winding spindle 40 as the latter arrive at the station C. During the travel of each spindle 40 from the {position indicated at D to that represented at E their rolle s.
05 will ride down the gradual slope of the raceway I2'I on the track 20 whereby to continuously lower the bobbins with respect to the traversecam I05. Due to this progressive displacement of the cores 1) with respect to the traverse-cam I05 the zone of traverse, indicated by dash-lines in Fig. 10, will be advanced lengthwise of the cores 0 from their heads h toward their tip-ends to eventually folm'filling bobbins B such as that shown at the extreme left in Fig. 10.
As the winding on each bobbin i completed during its travel from the position indicated at .U tothat represented at E the bobbin i returned to the dofllng and donning station to arrive at station C. During the advance of each finished bobbin B from position E to position C its spindle 40 will be elevated as the roller 65 on its bearing sleeve 58 rides up the sharply-inclined return portion I28 of the trackway 20. Duringthis upward movement of the spindle 40 a indicated at F in Fig. 10 it pulley 43 will be withdrawn laterally from contact with the driving belt We, as shown in Fig 25 and ,8, to arrest the rotation of the spindle and bobbin and thereby discontinue the winding on this bobbin. 7
As the roller 65 for each spindle 40 rides up onto the rest I25 the operator may sever the length of yarn leading to the bobbin, doif the 11111 bobbin 5 from the spindle and replace it with an empty core '0 while at the same time clamping the end of the yarn from the supply between the head h. of the fresh core and the head n on the spindle to prepare thi particu iar spindle forranother winding operation. it Will be observedirom the above explanation that the present bobbin winding machine operates continuously to travel the bobbins in an annularcourse during the winding operation and to advance them individually into position for coiling and replacement by fresh cores 0. 'While for the purpose of the present disclosure the doirlng and, donning operations have been explained as being performed manually, it is contemplated that automatically-operated means be provided for effecting these functions; but since such mechanism forms no part of the present'inven tion it is not herein shown or described.
During the winding operation the central column or standard comprising the vertical rod 80 is rotated slowly with the spindle-carrier 50 to which the rods are attached so that the supplypackages P mounted. at the upper end of the column will revolvetherewith. 7 When the supply of .yarn inflone package P is exhausted the connected strand delivering from anew package arranged below. or above as the case may be,.will feed downwardly to the bobbin B being wound. A fresh supply-package P then may be substituted. for the empty cone-tube or other yarn-carrier and the leading end of its strand tied to the trailing end of the yarn in the package from which the yarn is delivering. In this manner the supply'of yarn is maintained continuous with the result that the winding operation may proceed without interruption.
When it is desired to produce bobbins having angina in the direction indicated by the arrows in Fig. 9. To efiect thi reverse rotation of the spindles 49 the switch of the electric-motor l-3il may be shifted to reverse the direction of rotation of its armature shaft and pulley 13!. Referring to Fig. 9, when the bobbins b are rotated in counterclockwise direction the yarn-strands will be wound thereon in the same direction so as to draw off over the ends thereof in counterclockwise direction as is sometimes desired. Thi is especially desirable when certain kinds of yarns are to be used for Weaving since it is possible to obtain a'more uniform tension with less kinking ofthe yarn as thelatter delivers from the shuttle.
Regardless of the direction of rotation of the spindles t9 during the winding operation, the
spindle-carrier 55 must always rotate in counterclockwise direction, as viewed in Fig. 4, to insure thatthe rollers 65 will travel in the proper directionon the track 20. When'the direction of rotation of the countershaft is to be reversed the nut 58 on'the bolt It! is loosened and the bracket 53 rocked about the shafts l5! and I55 to mesh the worm 164 with theworm-wheel 41 on the spindle-carrier 59, after which the nut is tightened to hold the bracket in adjusted position. With the various parts adjusted in this manner the gear I 56 will be driven in the opposite direction from that first described to drive it companion gear [51 in reversedirection and turn the worm I64 to rotate the carrier 50 in counterclockwise direction to effect proper co operation between the rollers 65 and track 20.
Referringto Fig. 10, the sloping raceway I21 of the track 20 maybe formed with a profile. of greater or lesser inclination for different. lengths of bobbins or its cam-face maybe variedin other ways as required for different types of packages, all within the scope and purview of the present. invention. For example, to wind bobbins having parallel-sided cylindrical .body portions .on ta- It will be observed-from the foregoing speciflcation that the present inventionprovides a bobbin-windingmaohine which is of simple, compact construction While being highlyefflcient. inoporation. It also will beobserved that inv the present machine comprising a plurality of winding spindles arranged to travel about the centrally-located cam, common to all the spindles, the traversing means is reduced to utmost simplicity, thereby eliminating the. usual reciprocating yarn-guides and other parts liable to. wear and deterioration in use. It will be observed further that the meansfor advancingthe traverse of the yarn lengthwise of the bobbins is common to all of the several winding spindles and avoids the use of screw-threaded progression wheels, ratchet-devices and other complicated mechanisms. Thus, the present improved machine provides for winding a plurality of bobbins continuously at high speed by the use of extremely simple mechanism while requiring little attention on the-part of the operator. 7
