WINDING MACHINE.

Application led May l,

T 0 all whom may concern.'

Be it known that l, Jnisrns D. .leren7 a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State or' Pennsylvania, have invented certain new and useful Improvements in linding Machines, of which the tollowing is a specification.

This invention relates in general to winding machines for winding double taper' ended cops or Dobbins In Winding machines ot this type the taper of the end orc the winding is governed by a Shaper which controls the position of the contact or progression wheel, and hence of the thread guide carrier with relation to the spindle, during the early stages ot' the winding operation. When it is desired to wind a cop with a different taper it is necessary to replace this shaper with one having the desired pitch. Additionally such a Shaper must he replaced by another when it is desired to use the machine to wind a cop or bobbin having a tuhe ot larger' or smaller diameter, even though its pitch or taper remains the same.

lt is an object ot my invention to provide a shaper of novel design which is mounted on its support in such a mann u' as to permit ot adjustments ho'th to regulate the taper oft the winding and to accommodate the ma chine to the winding ot cops on tubes ot larger' or smaller diameters.

It is an object of my invention to provide an improved progression rod. or progression wheel and thread guide carrying rod, which is pivotally supported at one end and adapted to have angular adjustment laterally with respect to the spindle.

It is a further ohject of my invention to provide adjustable .means Vfor regulating the throw of my reciprocating` rod in accordance with the taper desired and the diameter ot the tubes on which the thread is to he wound.

lt. is another object ot my invention to provide anovel device for regulating the tension on the thread as it is traversed troni the small diameter of' one end ot tapered winding to the large diameter :it the other end of the taper.

lt is an another object ot my invention to provide a novel means on n y thread guide carrier for engaging with the shaper and for forcing the laterally adjustable thread guide carrier ron angularly toward the spindle.

1924. Serial No. 710,259.

@ther objects of my invention will appear in the accompanying specilication and claims and will be disclosed in the accom panying drawings, in which- Figure l is a side elevation with portions broken away of a portion ot' a winding' machine embodying my invention;

Figure 2 is a plan vievv of the device as shown in Figure l;

Figure 3 is a detail in perspective of my Shaper;

Figure fl is an end view of the Shaper shown in Figure 3;

Figure 5 is a detail in perspective of a portion of the means for permitting lateral adjustment of the progression rod;

Figure 6 is an end view partly in section of the device shown in Figure 5;

Figure 7 is a side elevation. largely in section, of the device shown in Figure 6; and showing` the means for securing my tensioning device to the traverse bar;

Figure 8 is a plan view, in detail, ot' my tensioning device in operative position;

Figure 9 is al section on the line 9 9 of Figure 8;

Figure 10 is a detail of the friction tensioning device.

Referring now with greater particularity to the drawings it will loe seen that my delvice is comprised. as follows:

The usual frame l, spindle 2 mounted in hearings 3 in the frame and driven through the disk 4f, is provided. A clutch and brake mechanism 5 together with a thread guide carrier and progression wheel assembly 6 are also provided as shown.

The traverse har 7 is slidaloly mounted in a hearing 8 in the frame l and is pivotally secured at 9 to: a link l() which in turn is pivotally secured to a suhstantially vertically extending curved arm ll lixedly carried by the usual roel; shaft l2. The link 10 may he connected with the arm ll at'any of the. apertures 1.3. This provides for adjustment to vary the throw of the traverse rod. The arm 11 is curved in suoli a manner that the traverse rod is always moved forward to the same point irrespective of the variation in the length of the throwof the rod. This structure is necessary to pei'- mit the proper functioning of the clutch mechanism.

The Ytraine .has lan upwardly 'extending i :1 rin .41.0. to which. there. is secured. a eviee Y41,`

cured tourna 41.0. iAtfa point below the. guide iii with the diameter thereof.

The lever 46 has atA one end thereof a laterally extending guide finger 47 which is so positioned that, upon oscillation ot the lever about its pivot, the finger 47 is adapted to pass between the fingers 43 and 44. The thread to be wound is fed over fingers 48 and 44 and under the finger 47. The other end of the lever 46 is slotted at 49 to provide a guideway for a pin 48 iiXedly connected to the traverse bar 7. Thus it will be seen that the traversing movement of the bar 7 will result in an oscillatory movement of the lever 4G around its pivot. Then the lever 7 is in its forward position, that is, when the thread is being wound on the small end oit the tapered winding, the linger 47 will move downwardly between the iingers 43 and 44 and take up the slack in the thread. When the bar 7 moves toward therearward position, that is, when the thread guide carrier moves toward the larger diameter ot' the winding, the finger 47 will be moved outwardly V'from between the fingers releasing "the tension on the thread and permitting' the slack to be taken up in the winding ot the larger diameters of the winding. By properly proportioningr the arms of the lever 46 and by correctly positioning the fingers 43 and 44 the desired tensioning' effect is obtained.

My device having been described in detail its operation will be seen to be as follows: The cop or tube to be used is placed on the spindle and the shaper adjusted longitudinally on its supporting rod in accordance The shaper is ihen rotated about the shaper rod until thc desired taper is reached. The traverse bar link is then adjusted in accordance with the length oi' throw desired. The thread guide assembly is then moved back ard along the progression rod. The finger'37 will then come in contact with the shaper and torce the rod 23 against the tension of the spring 30 out oi. alignment with the traverse bar 7. and laterally toward the spindle. This backward movement is continued until the contact wheel almost touches the spindle. The thread is then fed through the thread guide carrier and onto the spindle and the machine is ready tor the winding. As the varn is built up on the spindle, the progression wheel contacts with the same. moving the wheel outwardly along the progression rod and moving the finger 371outwardly along the sur'tace ot the shaper 32 until iinally the red 23 is in alignment with the bar 7 at which point the rear tapered end is completed. the body of the winding being cylindrical from thereon except for the taper ot the end which is being wound. The taper of both ends will naturally be of equal pitch though opposite in direction.

When t-he thread is being wound on the ysmall end of the taper the tensioning device,

as has been described taires up the Slack; and when the thread is traversed toward the larger diameters, this slack is gradually reieased.
