The machine illustrated'ln the drawings is particul'arly' adapted-foruse in winding a thread cop of the type of the one described and claimed in .the patent to Louis L. Moore No. 1,964,385,

dated June 26, 1934. This cop comprises a conical core 2 and a base 4 having its upper or'inner' surfaceconvex (Figs. 1 andi4). The thread 5 is cross wound, preferably a Universal wind being employed, on the core in such a manner that the re progressively displaced longitudinally of the tube sov as-to cause the inner or lower ends of the layers to be laid against the 2 convex surface 'of the base 4, the outer ends of the layersbeing conve'xedly arranged.-

As shown, the. machine. is provided witha winding spindle 6 and any suitable means suchv as the sleeve 8 .for detachably' securing a cup I tube'on the spindle, and a thread guide 10 for traversing'the thread longitudinally of the cop tube. The spindle 6 is carried on the forward end of 'a shaft I that extends through a bani-bearing H in the front of the machine frame, and its rear portion extends through a bushing sleeve l4 mounted in'an aperture inthe rear wall of the frame. A pulleyor wheel lliis secured on the projecting rear end of the spindle shaft ,I and is mounted totu'rn on a ball-bearing' l8 between its inner periphery -.and the outer end portion of the bushing sleeve M. The outer periphery of the wheel l 6'is provided with a conical, friction surface which is adapted to be positioned on a horizontal friction wheel 22. The wheel 22, only a portion of whichis shown in thedrawings, may be used to simultaneously drive a plurality "of windinglheads.

I6 is held rom rotary The friction wheel movement on the spindle shaft 1 but is permitted to he moved longitudinally thereof into and nut .jafengagement with the driving friction wheel 12. Inthe illustrated construction the wheel I6 is thrown out of operative enga ement as screw threads on the bushing sleeve I4 being left-handed. By turning the-collar 24 .in oppo site directions it is shifted longitudinally by means of its screw-threaded connection with the bushing sleeve 14 to move the friction wheel I6 into and out of operative engagement with the driving wheel 22. To thus shift the collar 24 it is provided with gear teeth 28 that are engaged by a gear segment 30 secured on one end of a rock shaft 32. This rock shaft is adapted to be tuned by means of a hand lever 34, secured thereon, in one direction to act through the segment 30 and. collar 28 to shift the friction wheel I6 into operative engagement with the driving pulley 22.. The friction wheel I6 is held in-engagement with the driving wheel'2 2 by means of a latch lever 38 (Fig. 11) pivoted at 38 on a bracket projecting from the-machine frame, said lever being pressed in one direction by means of a leaf spring 40. This latch lever 36 engages a roll 42 on the free end of an arm 44 secured tc the rock shaft 32, the roll being brought into holding engagement with the latch upon turning of the rock shaft 32 by means of the hand lever 34. Also, said movement of ,the rock shaft 32 moves the free end of ag-pivoted dogging arm 40 out of the path of 9. lug 48 formed ona disk- 49 secured on a shaft 50, the dogging arm 46 being connected with the rock shaft 32 through a link 54 and a collar 56 secured to the shaft.

At the completion of a predetermined number of revolutions of the spindle, 2. lug 58 formed on a disk 59 also secured on the shaft 50 strikes the lower end of the latch lever 36 and throws the lever out of holding engagement with the .roll 42, whereupon a coiled spring 60 connected with the gear segment 30 serves to t rn the shaft 32'. in a direction to shift the frict on wheel I6 out of operative engagementwith the driving wheel 22. j

During such operation of the machine-from the time that it is thrown into operation by means of the hand lever 34 until it is automatically thrown out of operation by means of the lug 58 a complete cop is wound. The wound cop traversing cam 62. The threadgu ide is mounted on the upper end of an arm 64 which may be of sheet metal which is mounted to slide longitudinally of the thread cop in a guideway formed by angular guide members 56 and 65 secured on a plate 68. The lowerend of this guide arm 64 extends through a slot 10 in the plate 68 andlits lower end is bent into rectangular form as shown in Fig. 9, and is arrangedrto'engage between transverse upstanding ribs 12 on the upper side of a cam follower I4 (Fig. -17). This follower I4 is mounted to slide in a guiding slot 16 which is formed by two upper guide plates I8 and -two lower guide plates 80, the slotted guide plate 68 being secured to the tops of the guide plates 18; The plates 18 and are secured byscrews 82 to' a casing 84 that surrounds the thread guide cam 52. Between the upper andilower plates 18 and 80 are secured plates 88, the inner 1ongl-,

tudinal margins of which project a distance into the slot I5 and are received in longitudinal grooves in the upper portion of the cam follower 14.

The guideway, including the slot I0 for the thread guide, is arranged parallel to the conical surface of the cop tube so that the guide is traversed parallel with the tube. The follower slot I5, however, is arranged parallel with the axes of the spindle 5 and the cam 62. The guide ribs 12 projecting from the top side of the cam follower allow for. the necessary movement of the thread guide supporting arm with relation to the cam follower.

In order to enable the thread guide arm to be easily connected with the follower, one wall of the slot It is provided with a notch 88 through which the lower end of the thread guide arm may be easily inserted and removed.

The thread guide cam 62 is provided with right and" left hand crossing spiral grooves 90, the upper portions of the grooves being relatively wide so as to receive the lower portions or shoe of the cam follower I4. The shoe has surfaces which in effect form segments of a nut accurately fitting the outer groove in the traverse cam, Figs. 14 and 15. The inner'portion of the groove in the traverse cam is relatively narrow to receive a supplemental shoe or pilot 92 that is formedon the lower end of a pin 94 pivoted in an aperture in the cam follower.

not be possible with a shoe having the usual rounded sides in which latter case a slight dwell would be necessary. Thus it will be apparent that with the use of my improved double cam groove and follower smooth and continuous motion of the follower is'insured. Y

The traverse cam 62 is formed on a shaft 95 which has its forward end mounted in a ballbearing98 in a cap I00 on the forward end of the cam casing 84, and its rear end mounted in a ballbearing I02 in the rear end of the cam casing 84, the cam casing being mounted in apertures in the front and rear sides of the machine frame. The cam shaft 96 is driven'from the spindle shaft 1 through a gear I04 secured on the spindle shaft which engages a gear I06 that is secured on one 7 side of a hub I08. To the other side of this hub is secured a gear IIfl which drives a gear II2 secured to the cam shaft 96. The two gears I06 and H0 and the hub I08 are mounted to turn on a bushing II4 (Fig. 13), and are held from axial movement thereon between a flange IIS on one end of the-bushing and a nut II8 screw-threaded on theother end of the bushing. This bushing secured on a pin or stud I20 that is secured in a block I22 mounted in a slot I24 in the machine frame, Fig. 9. This block I22 is split and has flanges which engage against opposite sides of the slotted frame member, the flanges being held tight against the frame member by a screw I25 when it is tightened, the tightening being possible a due to the resiliency of the block due to the split.

The stud I20 and bushing II4 are secured to the block I22 by means of a collar I28 secured on one of its ends and a'knurled knob III on, its 74 in the upper end of a supporting arm I62 (Fig.

area-ras- -3 other end. The gears I06 and H0 are of such relative size as .to cause the traverse cam 62 to rotate at a slightly less speed than the .spindle and thus'provide for the necmsary gain in the 6' winding. To vary this gain, the gears'I06 and H0 may be removed and other gears substituted, the gears being removable by removing the supporting block I22 from its slot and substitutin another block having the proper gears thereon.

10 In winding machines heretofore in general commercial use, the thread guide is moved outwardly during the winding operation by hearing on the thread mass as it is built up. In my improved machine, however, means is provided for 16 positively moving the thread guide outwardly during the winding operation. To provide for this, the cam casing 84 is mounted to turn in the front and rear sides of the frame and during the winding operation it is slowly turned in a direction to 20 impart the desired outward movement of the thread guide. The mechanism for thus turning the casing 84 comprises a cam roll I32 that is carried on an arm I33 projecting from a split sleeve I34 which surrounds the casing and. is secured thereto by means of a bolt I36 (Fig. 10).

r This cam roll I32 is mounted on a block that is mounted to slide in a guide slot I38 in the arm I88, which block is adapted to be moved to adjust the position of the cam roll I32 with respect to the cam I 42 by means of a screw I40. The cam roll I32 is adapted to be acted upon by acam I42 'carried by a shaft 50 hereinbefore referred to..

The cam roll is yieldingly held in engagement with the surface of the cam.I42 by means --of a.

weight I44 (Fig. 2) which is connected by a cord I46, that passes over a sheave I48, with a depend? ing arm I on the casing. The shaft 50 is driven, consequently the cam I42, so as to-make somewhat less'than one revolution during the w operation of completely winding a thread cop.

the shaft so that carries the cam m is journaied in bearings in the front and rear sides of the machine frame and is driven through speed reducing gearing I52 from the spindle shaft I.

, Thespeed reduction is such that the shaft 50 makes somewhat less than one revolution during the complete winding of a threadpackage. This speed ratio may -be varied to meet diiferent con- 0 ditions by changing one of thespeed reducing gears. To provide for this, one of the gears is mounted on a collar I54 that is secured on a shaft I56 journaled in a bearing block I58 (Fig. 13).

The gear is secured on the collar I54 by means of a nut and washer l60 on the shaft I56, which nut binds the gear against a shoulder on the collar. The bearing block I58 is mounted in an-aperture 11) which has its lower end secured on a bearing block I64 in which is journaled the shaft of another -one of the reducing gears. This bearing block I64-is detachably held in fixed position on the machineby means of a clamping'member I66 which is. secured .by. screws I68. This construction enables the gear on the shaft I56 to be easily 9,1 removed, and, when a new gear is substituted, it

' .gnay be positioned into operative engagement with the driving pinion I61 on the spindle shaft 1.

' Theshaftil'is connected with the speed reducing gear I52 through a friction slip clutch *7" comprising a member I10 secured onthe shaft 50 and a member I12 rotatably mounted on a hub of the-member I10. The two members have friction surfaces I14 which engage opposite sides of a gear-comprising a ring I16 that constitutes one i'iifof the gears of the chain I62 The forward end after described.

so as to permitthe completed package to be removed from the spindle and replaced by the next thread tubeor cop to be wound. The operator then still further turns the shaft 50 so. as to cause the tip of the cam I42 to pass the cam roll, allowing the casing to be turned by means of the weight I44 to, swing the thread guide into its initial position in close proximity to the core of the thread tube. Such turning movement of the shaft 50 by the operator is limited by the engagement of the dog 48 on the shaft 50 with the end of the latch '46. The machine is then ready to be again thrown into operation by means of the starting handle 34 which moves the driving friction wheel I6 into engagement with the wheel 22,

this driving engagement being maintained by the engagementof the latch lever 36 with the roll 42. Also, this movement of the handle 34 raises the latch lever 46 out of engagement with the dog 48,al1owing the shaft 50 to be driven through its connection with the spindle shaft.

It may be noted that by' angular adjustment of the dog 58 on the shaft 50 that the stoppage of the machine may be varied as desired, and that by angular adjustment of the dog 48 on the shaft 50 the initial position of the thread guide may be varied as desired. The dogs 48 and 58 are respectively held in adjusted positions by'lock nuts 41 and 51 threaded on the shaft 50 and clamping the dogs against the ends of a cam I herein- In the illustrated machine, means is provided for shifting the path of traverse of the thread guide with relation to the thread package so as to cause the successive layers of thread to, be progressively displaced longitudinally of the cop tube so as to form the package illustrated in Figs. 1 and}! of the drawings.

To provide for this, the casing is mounted to slide longitudinally and is shifted longitudinally during the winding operation to vary the path of movement ofthe thread guide with relation to the'package, by means of a cam I80 secured on the shaft 50. Thiscam is provided with apcripheral cam groove which receives a stud or roll I82 that is mounted on a boss I84 on a fork I86.

The boss I84 is mounted to slide in a guide slot in a fixed bracket i88 and the fork I86 is receivedin a groove I90 formed by a shoulder I82 on the casing 84, and a collar I34 secured on the casing. The groove of the cam I80 is such that the casing is shifted longitudinally during the winding operation to cause the path of the thread guide I0 to be varied; to eifect the desired progressive displacement of the layers of winding.

After the stoppage of the machine at the completion of the winding, the turning of the shaft 50 by the operator causes the cam I80 to restore the casing 84 and thread guide to their initial positions ready for the next winding operation of the machine.

In the illustrated construction, means is provided for stop ing the machine upon breaking of the thread. This means comprises an arm I86 which is secured to a pin or rock-shaft I 98 that is adapted to be turned inone direction upon breakage of the thread, by means of a rod 200 secured to the shaft I88. Upon such turning movement of the rock-shaft I", the arm I strikes the lower .end of the latch lever 36 and thus effects immediate stoppage of the machine. The arm 200 isoperatively engagedby the thread through suitable means, as for example, the thread guide rollers 202.

It will be apparent that any suitable thread tensloning means (not shown) may be employed in the machine.

In winding a cop provided with a conical base such as the one illustrated in the drawings. it i important that the thread guide lay the thread close against the surface of the base. The thread guide illustrated in the drawings comprises plates 2 and 206 on opposite sides of the thread guide arm 64. These plates are held in position on the arm by means of a screw which extends 20 through an elongated slot in the arm and is screwthreaded into the back plate I". This back plate is provided with an upwardly opening transverse s1ot'2l0 and the plate 208 is provided with a downwardly opening transverse slot iii,

5 the apexes of the two slots being spaced apart to provide a thread guide opening. The thread guide may be readily adjusted on the post by loosening the screw 20!. It will be noted in Pig. 5 that this construction of threadguide allows the thread to be positively carried close against the convex surface of the base of the cop tube.

With the machines heretofore commonly used for winding thread packages with the Universal wind considerable difilculty has been experienced in producing packages economically and of the desired uniformity. These packages must contain a definite yardage of thread, and it frequently happens the thread varies considerably in size. The thread is supplied to the machine from a quill or spool which results in substantial variation of tension between the delivery from a full supply quill or spool and a nearly empty one.

Said prior machines are usually equipped with measuringdevices-that control the stop motion of the machine. These devices have a'wheel around which the thread is carried in a path to the winding machine so that a predetermined number of revolutions of this wheel acting through a reducing gearing causes the win g machine to stop when the desired yardage hasbeen wound. 1

with these prior machines, owing to the variation in thread size and the marked variation in tension on the thread, it has been found diiilcult to wind the package of a given standard with respect to diameter. Moreover, in some of packages it is desirable to have the 00p soft wound as any undue tightness'of wind is likely.

to injuriously affect the elasticity in the thread. especally certain kinds of thread 'that are'soi't or unfinished. In prior machines, however, it has been found that any attempts to speed up the operation has tended to further increase tightness of the wind because of the increase' in the minimum possible tension at higher with my improved machine as illustrated in the drawings,'the'iinished thread mass, irrespective of variation in the size of the thread may be wound as closely as possible to the maximum diameter desired and extreme accuracy is attained in themeasuring-of thread.

In the present e the outward movement ofthe thread'guideinsteadofbeingeifectedby] the increasing-diameter oi thethread man, 3

m which makes something less than one reroiu tionduringthewindingctthepackage. m radial outward movement oi the thread guide so proportioned as to be exactly equivalent the movement which would be caused by the creasing diameter of the thread mam, wound with a thread of unvarying sine and under the desired diminishing tension and nishing guide pressure. 'Ijhus for any number of revolutions of the winding spindle radial distance from the face of the thread to the axis of the winding spindle would be the same and,- consequently, the length helix of thread laid on the periphery thread mass during any complete traverse of .the thread guide would increase in fixed portion to the number of winding spindle revolutions.

With this arrangement, by stopping the winding spindle after the proper ninnber oi revolutions of the spindle, the required yardage is wound and the thread mass is or more nearly standard dimensions. If the thread being wound should happentobesmallerthanthesineiorwhichthe machine was adjusted, the resulting finished package would be softer or less dense than standard especiallyinthecaseofsoftiinishedthreads. If the thread being wound should happen to be large, the resulting finished thread mass would be hard and dense.

Still another important advantage results from said combination of positive guide retraction with the thread measuring function. Heretofose, untversally wound packages of certain kinds a U thread suchas unboiled grey tend to buke'at the ends when the diameter of core is much ism 'thantheilnisheddiameter.
