To all whom it may concern: 1

Be it known that I, FRITZ BAUM, a citizen of the Republic of Switzerland, residing at. Rorschach, Switzerland, have invented certain new and useful Improyements in Auto- 1 matic lVinding-Frames; and I do hereby de- 4 clare the following to be a full, clear, and exact description of the invention, such .as

will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying ofthe windin of the next one, in such a way that, on the finished wound pirn or cop the ordinary central binding is produced and for the next pirn or cop to be wound a foundation is wound serving as the core for the pirn or co The objectof the latter winding is to enab e the thread, when the pirn or cop is unwound, to be drawn off uniformly from the conunencemerit to the end and thereby to avoid the thread breaking, such as takes place in machines with pirns or cops made on frames the thread guides of which have a constant movement, the foundation of the pirn or cop not being wound regularly but merely in an irregular confusion. This winding frame also consists in an arrangement by which the pirn or cop tube is rendered stationary by its being pushed forward by means of a device acting against the rear end of the pirn or cop tube shaft.

A form of construction of the objects of the invention is shown as an example in the accompanying drawings, in which,

Figure 1 1s a' side view; Fig. 2, a plan view with parts in horizontal section; F ig. 3, a front view. with parts in' vertical section;

frame. This has two iongitudinally dis placeable pirn or cop tube shafts 1 arranged parallel to one another and lying near together, which shafts carry the tubes 2 on The drawings show a double winding rear ends ofthe pirn tu e shafts.

which the pirns or cops are wound; also thread guides 3 which lay the threads in coils; feelers 4, which on the desired thickness of the pirn or cop being obtained couple up a mechanism which influences the thread guides, so that the foundations are laid round the pirns or cops and after the finished pirns or cops have been displaced to the ends of the pirn or cop tubes by dofl 'ers or scraping off devices 5 operated by this mebhanism, foundations are wound'on the pirn or cop tubes for the fresh pirn or cops to be wound. a

The means for operating the above mentioned main parts will now be hereinafter described. The pirn tube shafts are operated from the main driving shaft 6. For this ob- 'ect on the pirn tube shafts loosely revoluble ut undisplaceably arranged toothed wheels 7 are mounted in engagement with a toothed wheel 8 mounted on the main driving shaft, and for each pirn tube shaft a releasable key coupling is provided between said shafts and the toothed wheels looselyrevolubly mounted on them. Of these con lings the one for the left hand pirn tube shaft is shown in the drawings. -This coupling consistsof a pin 9 (Fig. 2) inserted in the hub of the toothed wheel 7 arranged on the shaft, a sleeve 10 with a recess or notch 11 on the shaft and a spiral spring 12. Now at the momentat which a pirn is to be drawn off, the coupling of the pun tube shaft on -which the pirn is mounted, is disengaged. This is effected by pushing forward this pirn tube shaft, wherey the pin 9 of the toothed wheel arranged thereon escapes'f'rom the notch 11 and the toothed wheel turns loosely on the shaft. Cam disks'16 are arranged on an auxiliary shaft 15 operated by a worm ear 13, 14, from the main driving shaft of the machine, for this ushing'forward of the pirn tube shafts, w rich cam disks act on upright levers 17 by the intermediary of rollers 19 (Fi s. 1 and 6) bearin a ainst the periphery of t 1e cam disks 16, w ic levers are ivoted on the bed late or foundation 18 o the machine and ear with their up er ends against the disks havea raised. art 16 which, as ,soon as it acts on the T0 er 1}) ofthe respective lever 17, pushes the pirn tube shaft forward. while as soon as the raised parts of the cam disks pass the rollers the spiral springs 12 of The cam SWITZERLAND, ASSIGNOR TO THE FIRM OF FRITZ BAUM 6: 00., OF R-ORSCHACH, SWITZERLAND.

- notches 32, as may be seen in the the coupling hereinbefore described, push by the intermediary of support pieces 48; -The supporting pieces are pivotally mounted in the arms 24 on bolts 48 (Fig. 3). Beneath these support pieces notc es 25 are provided on the arms 24', into which notches the lower arms of the thread guides may be drawn by means of spiral springs 26 engaging thereon. (Fig. 3 shows the thread guide of the right hand irn tube shaft in this position). When the t read guide 3 is in notch 25, as shown at the right of Fig. 3, arm 24 and thread guide 3 are rigidly locked together, and the eye in the thread guide oscillates in a long are whose center is that of shaft 23, but when the guide 3 is disenga ed from notch 25 and enters notch 27 the thread guide and its sup orting piece 48 is free to turn with bolt 48 however, the up er end of the guide is held in notch 27 whic 1 acts as a fulcrum, so that the eye of the thread guide will describe a much shorter arc of oscillation whose center is the notch 27 At the level of the upper end iece of each thread guide, a horizontal fixed plate 27 is arranged on the arm 24, on the opposite side of the thread guide to the pirn tu e, which plate has at the edge next to the thread guide a notch or slot 27 X (Figs. 2 and 8). Into these notches the u per end parts of the thread guides may e moved by means of arms 28 double armed levers 28, 29, mounted on the bed-plate and adapted to pivot horizontally (Fig. 3 shows the thread guide of the left hand pirn shaft in this condition); the other arm 29 of this lever lies within reach of the arm 30 of double-armed levers 30, 31, also mounted on the bed-plate and adapted to ivot horizontally. The other arms 31 of t ese levers lie Within reach of the action of cam disks 32 .Which. are loosely revolubly arranged on an auxiliary shaft 15 and form one piece with the cam disks 16; these cam disks 32 have a projecting part 32 (Figs. 2 and 7) and a notch 32* they form the one (loosely revoluble) half of clutch couplings 33 arranged on the auxiliary shaft. Rollers 34 fixed near to the cam disks 32 may drop into the ower part of Fig. 2. 35 are springs which tend to keep the halves of the couplings 33 apart.

Now when a co or pirn has been wound to the desired thic ess, the clutch coupling 33 belonging to the shaft of the tubeon which this pirn is wound is brought into action in a manner hereinafter described by means of the feeler. By this means the disks 32 and 16 forming one piece with one half of this clutch coupling are turnedby the auxiliary shaft and the raised part 32 of the disk 32 acts on the respective arm 31, whereby the levers 30, 31 and 28, 29 are displaced (Fig. 7) and the arm 28 moves the thread guide belonging to the before mentioned pirn tube shaft into the slot 27 of'the plate 27 belonging to this thread guide (Fig. 2 above and Fig. 3 left hand side). The ower arm of the thread guide is thereby drawn out of the notch 25 of the arm 24 carrying the thread guide. In this position of the thread guide it no longer makes the full movement with the arm 24, by which the thread guide was previously swung out to the entire length of the pirn or cop, but only makes a small movement, its u per part being retained or held by the p ate 27, so that the thread guide can only swing on this caught part; it is also carried along with the support piece 48, the pin 48 of which turns to and fro in the arm 24. This comparatively small movement of the thread guide causes the central winding of the pirn and later, after the finished pirn has been suitably displaced to the 'end of the irn tube by the doffer 46, the winding of t e foundation for the new pirn which is to be wound (Fig. 8). When the arm 31 is released from the projecting part 32*, the levers 30, 31, and 28, 29., return to their former position by the action of the spring 49 and the thread guide is caused, by the spring 26 to disengagefrom the notch 27 X of the plate 27 and to be again coupled with the arm 24. The cam disk 32 turns farther until its notch 32 faces the roller 34. At this moment, by means of the spring 35 belonging to the respective clutch couplin the half coupling which is displaceab e and revoluble on the auxiliary shaft is pushed back into its initial position, in which it is secured by the engagement of the roller 34 in the notch 32; during the turning of'the cam disk the roller 34 insures the engagement of the coupling by bearing against the back of the cam disk.

The engagement of the couplings arranged on the auxiliary shaft is operated from the feelers 4. These form one arm of double armed levers pivotal on horizontal axes, the other arm 36 (Fig. 5) of which has at 36 a sprin hinge and extends laterally to near the isks 16. For each of these double armed levers an inclined plane 37 (Figs. 4 and 5) is provided against which the arms 36 bear. Durin the winding the feeler which bears from ieneath against the pirn is pressed downward by the increasing size of the latter, the arms 36 being movedupward on the inclined plane, the consequence of '1'0 sition by springs 38.

As, however, the t which is, that the parts of the arms which are connected by hinges are moved not only upward but also si ewise, in such a way that thereby these parts ofthe arms operate the 5 displacement of the half couplings for the purpose of bringing the cou mgs into enagement (Fig. 5). The doub e armed levers forming the feelers are, after the removal of the pirns, again returned to their initial po- The operation of removing the irns takes place again from the auxiliary s aft. For this. object slide projections 39 (see particularly Fig. 6) aremounted on the cam disks 1 5 16, which projections act in conjunction with vertical draw-bars 40; these are guided at their lower parts by means of pins passing through uldes and have projections 41 against w ich the slide projections 39 strike ends of the drawbars 40 are connected with one arm 42 of elbow levers, the other arms 43 of which are forked. With these forks the arms 43 engage ms 44, which are supported by pieces 45 an carried by bars 46 arranged over the pirn tube shafts and displaceable in their directions. These bars have at their front ends doifers 5. For operating the doffers for the purpose of doffing the pirns, the slide projections 39 rotating with the disks 16 encounter the projections 41 and draw the drawbars 40 downward, while gradually slipping .611? the projections. The elbow levers 42, 43, are thereby dis laced and by means of the parts 44, 45, the ars 46 together with the doffers 5, are pushed forward, whereby the pirns are dofied. When this has-been done, the projections 39 slip down from the projections 41, whereupon the rails together with the doflers are again returned by the springs 47. Q As the separate parts of this improved winding machine have been hereinbefore I described as regards their form and method of working, this machine will now be further described in conjunction with a continuous method ofworkingl. When a pirn on a winding tube has reac ed sideration), that a central winding on the pirn is made. Then the pirn tube shaft is pushed forward and thereby it is disconnected from its operating mechanism and also the doffer is operated, which displaces the'last wound co or pirn so far toward the end of the pirn to e that a fresh pirn may be The pirn tube re'ad guide still continues to .make its diminished movement, a foundation is wound on the pirn or cop tube as a core for the new cop or pirn.
