WINDING-MACHINE.

Specification of Letters Patent.

Patented Nov. 16, 1909.

I Application filed December 7, 1908. Serial No. 466,399.

.T 0 all whom it may concern:

Be it known that I, SIMON W. \VAnownLL, a citizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island,'have invented certain new and useful Improvementsin VVinding- Machines, of which the following is a specification.

The subject of my invention is a winding machine for producing taper-ended cops for use in loom shuttles.

The invention belongs to that class of machines in which the cop is wound on a paper tube and built up with pointed ends and cylindrical body. The winding is initiated in substantially cylindrical layers which gradually progress forward and overlap each other to build up a conical face, upon which, subsequent layers'are wound to form the cylindrical body of the cop. The pro-' gression of the layers is eifected through the gradual feeding of the threadguide along its traverse bar .as the winding proceeds.

The object of my invention is to simplify and im rove this class of machines by providing or the progression wheel to feed the thread-guide from beginning to end of the winding without the use of a separate heel-- building or base-forming device.

The accompanying drawings represent respcctively:-Figure 1, a plan view showing the relation of the thread-guide and traverse-bar to the winding spindle; Fig. 2, a longitudinal elevation of the same, looking in the direction indicated by the arrow 2', Fig. l, and showing the traverse mechanism and the driving gears for the winding spindle; Fig. 3. a sectional view of the cop, showing the disposition of the layers of winding; Figs. 4, 5, .6, 7 and 8, details of construction.

Referring to Figs. 1 and 2, Z) is the winding spindle adapted to rotate in bearings in the frame 0 of the machine and preferably tapered throughout its length extending 1 outward from the frame to adapt it to receive the cop tube as, represented by dot-anddash lines in Fig. 1. The spindle is driven from the main driving shaft (l of the machine through suitable connections such, for

instance, as the skew gears e and f. The.

main portion of the traverse-bar g is arranged to reciprocate on a line parallel to the axis of the winding spindle and is driven from a rocker-arm h which is held by suiti able clutch-devices on the oscillating shaft 2'. r The main portion of the traverse-bar 9 slides in a bearing secured to the framec and is connected to the rocker-arm h by a link is. The rocker-arm h has a plurality of holes Z, Z, etc. arranged at varying distances from i the axis of the shaft i to provide for connecting the link 75 at diiferent points on the arm to vary the effect of the throw of the latter and change the extent of reciprocation of the traverse-bar. This allows for the adjustment of the traverse of the thread-guide to change the formation of the nose of the cop according as a long or a short taper is required.

In my application for patent, Serial No. 418,998, filed March 8rd, 1908, I have shown mechanism for rotating the winding spindle and traversing the thread-guide similar to that above described, but in my previous invention the machine is adapted to wind on bobbins or tubes having conical butts or .heads which support the first layers of yarn. In this style of machine the progression wheel which feeds the thread-guide along its traverse-bar is arranged to contact with the surface of the cop or bobbin at the end of each backward stroke or traverse, where the windin reaches its maximum diameter. Since the first layers of winding are built up on a conical former or butt all of the layers will have the same outside diameter and it is only necessary to provide for reciprocating the progression or contact wheel in a straight line parallel to the axis of the winding spindle. Each time the contact wheel is carried .back its periphery comes into contact with the surface of the winding at the pointof greatest diameter of the latter, and the wheel is given a. slight impetus to rotation which feeds the threadguide along the threaded traverse-bar and provides for the longitudinal increase in the growth of the cop. In .the present invention, however, the initial layers of the cop are wound on a thinpaper tube, the butt being dispensed with, so that the first layers are of comparatively small diameter. It-is therefore necessary to provide means for swinging the traverse-bar into closer proximity to the winding spindle at the beginning of the winding to maintain the progression wheel in position to contact with the first formation layers of the cop. The automatic devices for securing this adjusta; crease ment of the contact wheel in proportion to l the diameter of the layers of winding form the essential feature of the present invention and will now be described.

The traverse-bar which carries the threadguide is made in two sections, the main portion g being adapted to reciprocate in astraight line parallel to the axis of the winding spindle, as before explained, and the part m connected to the main portion by a pin and slot arrangement which allows the inner end of the bar at to be moved laterally toward the winding spindle. The outer; end of the bar 7% slides in a bushing n which is swiveled in an outward bearing 0 fastened i to the end of an outrigger bracket p-secured to the main frame, see Figs. 1, 2 and 4. Referring to Fig. 4, the bushing 02 has an' annular enlargement n fitted to the bore 0 of the bearing 0. This allows the bushing to swing in the bore, as shown in Fig. 1, and a stud 0 is screwed into the bushing with its end engaging a hole in the bearing 0 to retain the bushing from displacement. The

bearing 0 is bored to a depth sufficientto" allow the bar m to slide through the bushing its full extent of traverse, as represented in Fig. 4. r

Mounted on the traverse-bar extension m is the thread-guide-holder 1, of bifurcated form with two legs 1, r, the extremities of which surround the bar to form bearings thereon. .The opposite end of the threadguide-holder is adapted to receive and hold the thread-guide s which is formed with the usual slot 8 serving as a passage for the thread or yarn'y. The arrangement of the bearings of the thread-guide-holder on the traverse-bar allows the thread-guide s to oscillate to and from the winding spindle to adapt it to follow the taper of the winding on the nose of the cop. The bar m is formed with partial screw threads m cut into the surface eccentric to its axis, see Figs. 7 and 8. Located between the two legs r 1 of the thread guide-holder r is a nut t having its bore internally threaded, but of sufficient diameter to slide freely over the threads on the bar on when concentric with the latter. Secured to the nut t is a disk or wheel a which has been termed the progression or contact wheel because it acts to contact with the rotating cop to turn the nut 25 and feed the thread-guideholder along the traversebar. As before stated, the nut t-is free to slide over the threads on, the traverse-bar when concentric with the bar, but to maintain the nut normally in engagement with the threads m I provide a spring o secured to the thread-guide-holder r and arranged with its free end bearing on a flange a on the wheel 10. During thawinding, when the I thread-guide s bears against the cop, as shown in Fig. 7, the effect of the spring 1) will be to keep the nut t engaged with the threads on the bar m, but, by swinging the thread-guide-holder t upward, as shown in Fig. 8, thiscfiect of the spring 1 will be annulled and the nut will return to a position concentric with the bar. In this way the nut can be disengaged from the threads on the traverse-bar so that the thread-guide .of the progression wheel in in close proximity to the winding spindle at the beginning of the winding will next be described.

As before stated, the two adjacent ends of the sections 9 and m of the traverse-bar are joined with a pin-and-slot connection. The end of the bar 9 is slotted at 9 and also bored with the axial hole g see Figs. 5 and 6. Inserted in the slot 9 is a plate 2 formed with a tongue 3 projecting into the bore g". A. pin i is driven down through the rod and the plate to secure the latter in its position in the slot y and the tongue 3 acts to steady the plate to prevent play. A slot 5 is provided in the plate 3, extending perpendicular to the rod g. The end of the rod on is also slotted at m to receive the plate 2 and drilled with a transverse hole through which the pin or wire 6 projects down into the slot 5'. The opposite end of the wire is preferably coiled partly around the rod at 7 ,to hold the pin in place. The outer edge of the plate 2- is formed as a cam face 8 arranged at an angle'to the axis of the rod 7. The end of the rod m has an axial bore m and a plunger 9 is fitted to slide therein with its end adapted to bear on the cam face The plunger 9 is turned down throughout a portion of its length to form the shoulder 10 and surrounding this reduced portion is a coiled spring 11. The spring 11 is held under tension between the bottom of the bore in and the shoulder 10 and acts to force the end of the plunger against the cam faceS. Preferably, this end is slightly rounded to adapt it to slide smoothly on the cam. The effect of this arrangement is to normally maintain the bar m in axial alinement with the bar g, as illustrated by The means, for swinging the end of the.

bar at towardathewinding spindle consists of a guide or former 12 having an arm 14: adapted to bear'on an extension 13 ofthe thread-guide-holder 7. The former 12 is preferablyattached to the plate 2 in such finger engages it from the action of the arm 14. At the r lower end of the member 13 1s suspended a a way to be easily removed, so that other formers of different shapes may be substituted when it is required to change the form of the cop. The arm 14 on the former 12 extends in the same plane as the axis of the traverse-bar, at a slight angle thereto, and the angle at which the arm 14 is formed determines the angle of taper at the end of the cop, as hereafter more fully explained. The former 12 is secured to the plate 2 by means of a screw 15 extending through a slot 16 and screwed into the plate. A second slot 17 is adapted to receive the end of lhe.pin at which secures the plate 2 in the end of the bar g. The two slots 16 and 17 provide for adjustment of the arm 14. toward or away from the spindle b so that the progression wheel umaybe set for tubes of different diameters. An car 18 is turned down from the main portion of the former 12 and abuts the edge of the plate 2 to locate the former on the plate. The arm 14: is bent down in angle form along the edge which is engaged by the member 13, see Figs. 7 and S, to provide a more extended bearingsurface for the rim of said member.

The member 13 is attached to the leg r of the thread-guide-holder r and takes the shape of a quadrant, its outer edge formlng an arc concentric to the axis of the bar m. The area] form of the member 13 allows the thread-guide-holder 1' to be turned upward, as shown in Fig. 8, without releasing finger 19, pivoted at 20. The finger 19 is adapted to contact with a rod 21 which extends outward from the frame of the machine parallel with the winding spindle, see Fig. 2. A lug 22 on the upper end of the the member 13 when the thread-guide-holdcr is swung upward to the position shown in Fig. 8, and acts as a stop to prevent further movement ofthe threadguide away from the winding spindle. ThlS' provides against accidental. turning of themember 13 out of range of the arm 14.

The operation of the whole machine is as follows: The tube 05 is forced on to the tapered spindle 7) and the end of the thread or yarn g secured at the inner end of the tube. At the start of the winding the thread-gu1de s will be in the position indicated by full lines in Fig. 1, with the thread-guide-holder 2' at the inner end of the bar m. The member 13 will bear on the arm 14 at the inner end of the latter and the traverse-bar-extension on will be held in the position illustrated by full lines in Fig. 1 with its axis extending at an angle to the axis of the bar Tlie progression wheel a will be held in the position shown, with its periphery just clear of the outside of the tube a: at the latters larger end. Referring to Fig. 2, the link is is connected to one of the holes 1, 1, etc. in i the arm 71, accordingto the extent of traverse of the thread-guide required. As here shown the link isconnected at the end of i the arm h to give the maximum extent of traverse so that the cop Wlll have a comparatively long nose. 1th some varieties of material, such as silk or hard-twisted thread,

and the oscillating arm It, through the linkls, causes the traverse-bar g to reciprocate. The thread-guide-holder r is traversed in a line substantially parallel to'the axis of the winding spindle and the thread-guide s follows the surface on which the winding is.

being performed, being held close to the winding under influence of the tension on the running yarn 3 which draws down through the groove The first layer of winding, indicated by 10, will be disposed on the tube a; in a plane conforming to the surface of the tube. This layer will be tapered only to a slight extent, equal to the taper of the tube 0, but the rear end of the layer will be slightly larger in diameter than the forward end. This provides that as the progression wheel u traversesalong the winding spindle substantially parallel to the axis of the latter it will make contact with the Winding only at the rear end of its traverse. In other words, it will contact with the winding only at the base or pointof largest diameter of the layer. lVhen enou h coils have been wound on to the tube to eti ect this contact of the wheel at the base of the cop the wheel will. be rotated from the rotation of the spindle 7) and the nut t 'will advance along the traverse-bar m, carrying with it the thread-guide-holder 1' and thread-guide s. T he length of traverse of the thread-guide remains constant throughout the Winding of the whole cop, so that as ber 13 rides out on the arm 14, allowing the end of the bar m to move laterally away from the spindle I) under influence of the plunger 9 pressing against the cam face 8. This provides that the wheel at shall be kept in proper relation to the spindle 72 to be in positlon to contact with the base end of each layer of winding as the heel of the cop increases in diameter. The heel of the cop will take the form indicated in Fig. 8, with a taper corresponding to the angle of the face of the arm et. The winding reaches the maximum diameter when the bar m has been carried out to a position with its axis alining with the axis of the bar 5 and the pin (3 will then be at the end of the slot 5 to limit the bar in from further movement. At this point the member 13 rides off the end of the arm 14, as illustrated by dotted lines Fig. 1, and the two portions of the traverse-bar m and 9 remain in alinement and form practically one straight, continuous bar during the rest of the Winding.

From the point 10 Fig. 3, the winding continues in conical layers wound on to the tapered surface formed by the overlapping of the ends of the first, formation layers in the heel of the cop. As the thread-guide advances along the traverse bar at each reciprocation, the base ends of the layers will all be of uniform diameter, or, in other words these ends will aline to form the cylindrical periphery of the body portion of the cop. The thread-guide s oscillates to and'from the winding spindle at each reciprocation to adapt it to follow up and down the taper of the Winding so that the laying of the coils is accurately and precisely controlled.- When the traverse of the thread-guide reaches the end of the cop tube a: the machine is stopped and the completed copremovedl To prepare the machine for winding a new cop the thread-guide-holder 1* is swung upward away from the winding spindle until the spring *1) is removed from the position where it engages the nut t With the threads m on the traverse-bar m. The t'hread-guide-holder r is then pushed back along the bar m to its initial position at the inner end of the winding spindle. As the threadguide-holder r is slid back the member 13 rides along the incline of the arm 14 and forces the end of the bar on laterally in toward the spindle b so that the wheel u will be in proper position to contact with the first layer of winding. The'winding is then started as before described.

lt will be understood that by substituting progression wheels of different diameters the diameter of the cop may be varied as desired, and by altering the angle of the former arm lat and changing the traverse of the thread-guide the formation of the tapered ends of the cop may be controlled.

It will be obvious that my invention is susceptible of modifications in structure and arrangement and therefore I do not limit myself to the exact form. shown and described, but
