Application filed march 3, 1921. Serial No. 449,579.

To aZZ whom it may concern:

Be it known that I, HENRY G. JOHNSON, a citizen of the United States, residing at East Hampton, in the county of Middlesex and State of Connecticut, have invented new and useful Improvements in Universal Winder Heads, of which the following is a specification. This invent-ion relates to machines for winding thread on spools, and has particularreference to means somewhat in the nature of an attachment to what are known as universal winders, whereby a spool or tube having a head at but one end can be wound with the thread in layers.

The object of the invention is to provide means which will so lay the wound thread that the surface of the layers at the end of the spool or tube having no head will be tapered or beveled, whereby the thread is unlikely to fall off at that end, and the thread can be freely drawn from that end without encountering any spool head.

The object mentioned is accomplished by automatically efi'ectlng a gradual longitudinal shifting of the rotating spool, and the traverse of the thread guide or eye relatively to each other. In the illustrated embodiment of the invention, the thread guide, during operation, has a traverse of a given length, so that the number of coils in allthe layers are always the same for a given length of spool or tube. As the layers of thread are superposed one upon the other, the thread guide is pushedaway from the axis of the spool, by the increasing diameter of the windings, and this movement of the guide is utilized to gradually shift the relative positions of the spool and the traversing thread guide in the direction of the axis of the spool. In the machine illustrated. it is the spool which moves longitudinally.

With the above object in view, the invention consists in the mechanism substantially as hereinafter described and pointed out in the claims.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is an elevation of the machine, omitting such parts as are well known in this type of mechanism.

Figure 2 is a top or plan view of the same, omitting the traversing cam which appears in Figure 1.

2 of a rod 'or bar I) mounted to slide in a guideway of the swinging support 7. One face of the thread guide is beveled, as at 3,

to substantially correspond with the angle of the face of the head 4 of the spool 5. This bevelingof the guide 3 is to enable the thread, which runs through the notch or eye 3", to be laid close to the spool head 4 (Figures 6, 7, and 8). The support 7 is pivotally mounted on the j aek shaft 8, by means of arms 7 of the said support, and suitable counterb-alancing devices, such as are usually employed in this type of winder, may be employed to exert a tendency to press the guide 1 toward the spool.

Secured to the member 7 is a plate 9 having an upstanding pin 10 on which a block the parts when the spool is 11 is mounted. Slidably fitting a transverse the two arms 12 and 16 practically constituting an elbow lever. A fitting 17 is adjustably secured on the arm 16 by a set screw 18, and has a vertical pin 19. 20 connects the pin 19 with a fitting 21, secured by a set screw 22 to a slide rod 23, mounted to reciprocate, but not rotate, in bearing ears 24 of a bracket 24 rigidly supported on short arms 25 by clamp clips 25*. The arms 25 frame of the machine by screws 27.

Rotatably mounted on the outer end of. the ,rod 23, is an externally threaded sleeve 28, held between collars 29, secured to the rod by set screws 30, said sleeve having a knurled. portion 31 for convenience in ro-- tating it. Mounted on and engaging the threads of the sleeve 28 is the internally threaded hub 32 of an arm 33, forked at its outer end and engaging an annulangroove A link are secured in ears 26 of the 34 in the spool mandrel 35. The mandrel is slidably mounted on the extended portions 36 of the main shaft 37, the driving connectionbetween said shaft portion and the mandrel being maintained by a key 38 and key-Way 39 (Figure 3).

A belt pulley 40 mounted on the shaft 37 is adapted to be connected thereto to drive it by a suitable clutch mechanism, not necessary to illustrate, the engaging operation of the clutch being effected manually by a clutch lever 41 at one end of a clutch-operating shaft 42. The throwing off of the clutch is usually effected automatically, by mechanism not necessary to illustrate, as it forms no part of this invention.

The shaft 37 also carries a pulley 43, connected by a belt 44, with a pulley 45 which, through suitable speed-reducing gearing in the casing 46, drives'the jack shaft 8 carrying the path cam 47. Said cam 47 engages a roll carried by a pin 48, which projects down from the slide In operation, an empty spool is secured upon the mandrel by the tapered plug 49 acting in the usual way to expand the split portions of the mandrel, and at the start of the winding the thread guide 1 bears against the spool about as indicated by the full lines in Figure 6, this being effected by the usual counterbalancing mechanism, not necessary to illustrate herein. During winding of the first layer the cam 47 effects a traverse of the slide 5, and its arm 2', to the position indicated in Figure 1, carrying the guide 1 to about the position indicated by dotted lines in Figure 6. As the return layer is being woundthe guide 1 bears on and rides'along the first layer, resulting in swinging the arm 2 and the support 7 back. The plate 9 and its pin 10, carried by the swinging support, transmits this motion through the elbow lever 12, 16, to the link 20, and through the latter to the slide rod 23 and the fork'arm 33, which latter effects a slight longitudinal movement of the mandrel and I spool toward the right (Figure 2), or toward the outer end of the shaft 36. The parts are so proportioned that this longitudinal movement of the spool equals the diameter of the thread being Wound. As the winding progresses the thread guide is pushed farther and farther away from the axis of the spool, and the spool is shifted more and more to the right as shown by comparing Figures 6, 7, and 8, thus presenting a filled spool having the exposed end tapered or beveled.

Preferably the angle of the bevel is at 45 to the axis of the spool, corresponding with a similar angle of the inner face of the one spool head 4.

To secure the best results it is, of course, essential that the thread filling shall, be compact. To this end it is important that the .parts of the machine are so proportioned and commodate spools having heads 4 of different thickness.
