y 14 Claims.

This invention relates chines particularly cone winders, and has for one objects to provide a new and' of its principal simpliiied construction vof cone-holding and supporting mechanism adapted to increase or accelerate the taper of the winding cone as the package grows. It has long been recognized that an increase or acceleration in the taper of the winding cone is desirable and vcone winders generallyv are equipped with some form of mechanism for manipulating winding to increase its inclination to the winding package drive roll. An object of the present invention is to produce the desired increase in the taper of the winding cone without complicated mechanism by making use of a new relation between the cone holder, the winding package drive roll and the package arm which supports the cone holder.

A further object of the invention is to provide an improved and simplified mechanism for retracting the cone holder during the growth of the cone so as to produce a retracted cone.

4Other objects of advantage and utility will/be apparent from this specification and its drawings wherein the invention is explained'by way of example.

The invention is shown by way of example as applied. to a traveling spindle Winding machine of the general type disclosedin my United States Patent No. 2,135,485 dated November 8, 19384 in which the winding packages are carried by individual units which travel along a guideway while the winding packages rest upon a winding pack-l age 'drive roll.

29,` spindle 30, cone holder Referring to Figs. 1 and 2, the head portion Il of the winding unit is provided with wheels I2 adapted to run on a track or guideway I3 over` which there is arranged a long winding package drive roll I4. A cover plate IS on the head4 of the a support orsuitable yarn guides I1, tension disks I8, and a slub catcher I9; a traverse cam 20 mounted in the head of the winding unit carries cork tires 2l which are frictionally engaged by the roll I4 so as to -rotate the cam,

roll I4.

A package arm 26, pivotally mounted at 21 on -a vertical extension 28 of the head of the unit, has integral therewith a sleeve 29 which as indicated in Fig. 5 carries a spindle 30 on which the cone holder indicated generally at 3l is mounted.

In the various figures, the axis of the sleeve dicatedA by a line W-W and the axis of the vcimiing package drive roll is indicated by a line A preferred construction of the cone holder Il is shown in Fig. 5. The spindle 30 extends throughout the length of the cone holder and carries at its left end a headed screw adapted to retain the rotatable portion of the cone holder on the spindle. A sleeve 42 is mounted for rotation around the spindle 30 and is provided with conical portions 42 and 42b adapted to fit the inner surface of the paper cone 32. The cone is to the cone holder by means of prongs 45 pressedoutwardly by springs 46 which are secured to the sleeve 42. The bearings on which the sleeve 42 turns on the spindle 3U are preferably constructed according to the principle described in my copending United States patent application Serial No. 193,006 filed February 28, 1938. is provided with a cup-shaped portion 5I holding a wooden or fiber bushing 52. A

tubular element 42 preferably of steel and fast on the sleeve 42, extend-s within the bushing 52 so that the bushing thus constitutes an external bearing surface for the right end and the cam reciprocates a traverse yarn guide 24 closely adjacent to the 3l and cone 32 is in- A sleeve 5I) fast on-the spindle 30v `handle 1 I.

the package when raised toits idle position. For unlocking the prongs 45 from the paper cone, there is preferably Iprovided a cup-shaped unlocking member 10 rotatably mounted on the sleeve 50 and having a handle 1|. A pinf12, fast inthe sleeve 50 engages in a cam slot 13 in the member 10 to. force this member 10 over to the left when the handle ispushed away from the observer in Fig. 5, thus causing the member 10 to force the springs 46 inwardly and disengage the prongs 45 from the cone. A spring 1 is employed to restore the member 10 to the right when the handle 1| is swung back toward the observer.

It will be observed that since the cup-shaped member 10 is mounted to turn about the axis of the straight spindle 30, this cup-shaped member regardless of the position of the spindle, is always in alignment with the springs 46, ready to act on these springs when suitably turned by the Moreover, in connection with the 'feature of endwise shifting of the spindle and winding cone during the winding, now to be described, it is to be noted that the cup-shaped member 10 accompanies the spindle in such shiftlng movement, so that operation of the unlocking handle 1| neither tends to shift the spindle nor reacts upon the mechanism for causing such shift of the spindle.

As indicated above, the device preferably includes a means operated by the swinging of the package arm 26 to shift the cone-holder and winding cone endwise with respect to the package arm, and mycopending United States application Serial No. 47,247 filed October 29, 1935, Patent No. 2,157 ,105 may be referred to as claiming this preferred feature broadly. In the illustrated device, this endwise shift of the cone-holder is to the right or toward the package arm'26 as the winding cone grows, and is suiicient in amount to'produce the concavity of the cone nose and convexity of the cone base shown in Fig. 8. Referring to Fig. 5 which shows the coneholder in its fully retracted or right-hand position, the spindle 30 is recessed at 56 to receive the end of a lever` 51. which is pivoted at 58 to a casing 59 fastened on the arm 26. The lever 51 thus prevents the spindle 30 from rotating with the face of a cam 6| mately 35 movement of the package arm from respect tothe arm 26. A roller 60 at the 4 Aopposite end of lever 51 runs in contact with (Fig. 6) during the approxithe start of winding until the completion ol' an eight inch package. The shape of this cam 6| (Fig. 7) is such that at the beginning of winding on a bare cone the cone holder is held by the lever 51 in its left hand position of Fig. 1 a substantial part of the -reduced diameter `portion 29" of the sleeve 29 being exposed). During the giowth of the cone, a spring 63y acting on the lever 51 within the casing 59 urgesvthe lever 51 in a clockwise direction in Fig. 5 and thus progressively shifts the spindle 30 and cone holder 3| to the right. By the time of completion of an eight inch cone, the cam 6| has permitted the spring cause complete retraction of the cone 'holder to a position with reference to the package arm 26 such as shown in Fig. 5.

In addition.to the force of the spring 63 tending to shift the spindle cone holder and winding package endwise toward the package arm, a similar force is exerted by the package drive roll directly upon the winding package due to the inclination of the spindle, cone holder and package with respect to the drive roll, described below.

The cam ilfcam follower and lever 51 act in a positive manner to control the endwise movement of the spindle, cone holder and package toward the. package arm, so that the package is prevented from moving more quickly to the right than is necessary, to produce the desired shape of the ends of the package.

According to the present invention the cone holder 3| (and bare cone l2) is initially inclined to the drive roll M when the bare cone rests on the roll. The tip of the cone `is inclined toward the side of the roll at which the arm 26 is pivotally mounted, the inclination being suiilcient in amount so that substantially throughout the winding of a full cone, the axis of the cone (i. e. the line W-W) progressively approaches a plane passing through the axis of the drive roll (i. e.

the plane Y-Y). In this Way, vby a simple pivotal movement ofthe package arm 25, the taper of the winding cone throughout the winding, in a continuous manner. Referring to Fig. 1, the up of the bare or approximately bare cone is inclined toward the pivot side of the machine approximately 9 with respect to the axis oi' the drive roll. Fig. l shows in plan view the approximately 9 inclination of the cone holder axis W-W with respect to the drive roll axis X-X, and this inclination can be seen in side elevation in Fig. 2. As the package grows, this inclination which initially has a large horizontal component is translated progressively into a downward inclination, as may be seen by a comparison of Figs. 2 and 3. The axis W-W of the cone progressively loses its horizontal inclination to the axis X-X of the drive Iroll and becomes 'more inclined to the drive roll in radial direction. The axis W-W of ally approaches, but preferably does not quite reach, a radial plane Y-Y shown in Figs. 2 and 3 passing radially through the drive roll axis x-x. obviously if the :mm1 horizntai inclination of thecone holder axis W-W were not sufciently large, a slight growth of the winding package would carry the cone holder axis W-W past some such radial plane Y-Y, with the result that during the subsequent growth of the package, the radial inclination of the cone holder axis 4W-W to the drive roll axis X-X would progressively decrease and become reflected in a progressively increased horizontal backward component of inclination, this movement decreasing the taper of the winding cone.

According to the the axis of the cone holder, at the time of completion of the full package (such as an eight inch cone) does not quite attain or at least does not substantially pass any plane Y-Y which is radial to the drive roll axis X-X. Therefore, thereis 4no loss ofv taperof the cone in the last steps of the length or the cone into contact with the rou until finally practically the entire length of the cone .is in contact with Figs. 1 and 2, the cone holder is initially posiis accelerated substantiallyv the cone continu-K present invention, however,

Referring to 2,281,019 v tioned so that the cone is driven by frictional portion with the drive roll. the tip portion of the cone tendency forthe by the drive roll contact of its base The yarn wound on is laid firmly and without any cusps of yarn tobe loosened which has a much V that of the tip portion of the winding cone. Then as the winding cone grows, and the surface speed of the smaller end to the surface speed of theairive roll, the position of the cone with relation to the drive roll is progresively altered to bring substantially all or nearly all of with the roll, as shown in Fig. 3.
