wINnINe rms Application led April 24, 1922. Serial No. 556,213.

To all whom it may concern.:

`Be it known that I, XAVER BRGGER, a citizen of the Republic of Switzerland, residing at Horgen, Switzerland, have invent` ed certain new and useful improvements in Winding Frames; and I do hereby declare the followingl to be a full, clear, and ex. act description of the invention, `such as vwill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanylng drawings, and to letters or figures of reference marked thereon, which form a partl of this specification.

The well-known winding frames provided with spools havin on the side on which the drive is locate a bearing which opens upwards, present the drawback that in Winding up the thread which comes from the thread holder, the spools vibrate, thus causing an unequal, hard and soft winding. The result thereof is that these spools must be re-wound. l

The same drawback is inherent in the well-known. weft winding frames in which a revolving spindle supported at one end carries the spoolsL" According to the invention, this drawback is eliminated by providing the ends of the driving shaft with friction disks with taper bores for the purpose of having coaxially supported, at one of their ends, two spools on which the thread is to be wound, the other ends of these spools being lodged in disk bearings 16 provided with comcal bearing surfaces and subject to the action of springs.

Une embodiment of the invention is illustrated, by way -of example, in the accompany/ing drawings, in which Fig. l1 shows the winding frame in front view, partially in section, and

Fig. 2 in a side view.

Figs 3 and 4 show dia' rammatically a modification of the threa holder 'in side view and in plan'respectively.

The frame 1 (omitted in F ig. 1 for the sake of clearness) carries two bearing standards 2 with three bearings 3, 4 and 5 each. The central bearing 4 carries'the drivingshaft 6 for the spools 7. rEhe drive is e'ected by means of cords Vfrom the shaft 8, Disks 9 are secured to both ends of the "driving shaft 6, said disks fitting into the pedestal of the bearing 4 so as to' ensure an exactly axial rotation-of the shaft. rlhe vcoidal springs 15. being these two supports.

p spools for example.

disks 49 are provided with taper bores 10. The shafts 11'of the bearings 3 and 5 are supportedby the pedestals of these bearings at 12 and by thedisks 14 which are adapted to be shifted in axial direction and tightly it into the bores 13 of said pedestals, heliinterposed between he shafts carry, on their ends facing the spools 7, disks 16 rigidly connected with the shafts 11 and provided with the tapered bores 16. order to reduce the friction between the

disks

14 and 16, balls 17 are interposed.

In order to enable spools of various lengths to be wound, the bearings 3 and 5 may also be adapted to be shifted relatively to the central bearin 4.

If a spool is to ie lodged between the shafts 6 and 11, one end of the spool is introduced into the taper bore of the disk 16 and the bearing pushed so far away as to allow the other end of the Spool to be introduced into the taper bore of the disk 9 of the central bearing. It is obvious that the drive of the spools could be e'ected from either side of the spools without any difiiculty from the point of view of construction. ln the same way, the central bering could be adapted to be shifted axia y.

in the upper portion of the'winding frame the thread holders, reels for instance, are located. The reels could also be replaced by The

reels

18 and 18 supply material to the 'front ools whereas the

reels

18 and 18 supp y material to the rear spools. This arrangement of lthe spools enables the length of the machine to `be considerably reduced.A In order to stop the rotation of the spools in the case of an insufficienty supply of material, the following arrangement is provided.

An angle lever 20 is fulcrumed pivotally about its axis 21 in the bearing 19. IThe free end of the lever arm 20 faces the front f surface 7 of the spool whereas the freehend of the other lever arm 20 of said angle I lever bears against the free end of the lever arm 22 of another angle lever 22 fulcrumed pivotally about thepivot 24. The lever arm .22 of the. angle lever 22 carries on the top a pin 23 extending over the whole widt of the reel. Should it now happen that the thread is not wound ofi' the reel normally,

but is caught in the material on the vreel and taken along in the direction of the arrow p Fig-2, the -thread strikes against the l in `23 whereby the angle lever 22 and thus t e an-V 'le lever 2O as well is operated upon.. The ever arm 2Q now presses against the spool and pushes 1t away from the driving shaft,

Vthe coupling between said shaft and the spool belng thrown out of gear thereby.

'Instead of a friction coupling, a clutch or claw coupling, for instance, could also be applied between thedrivingv shaft and the s col.

It a pens that the thread running oli' the thread older towards the spools is caught in the material not wound of, thus causing the thread to be subject to an unequal stress,

that isto say: it is subject 'to an excessive tensile stress inthe case of such derangements whereby the structure of the thread is ai'ected. The same occurrence takes place when starting the machine, the thread holder being set in motion j erkily.

This drawback is avoided by .supporting i the thread holder in such a manner that it can be shifted in the direction of its height..

The journals l, Figs. 3 and 4, of the thread holders 2 lodge in the bearings 3 of the arms 4 of the pendulum 5, said bearings being open upwards. This pendulumlis pivotally funerumed at 6a. The arm 7L of the pendulum carries a counterpoise 8f adapted to be shifted and fixed on arm 7 for the purpose of balancing the pendulum with the thread holder.

The working of this method of lsupporting the thread holder is readily compre ensible. Should a derangement occur in the supply l of material whilst the machine is working,

by preventing the thread from readily detaching itself from the other material, the increased tensile force acting upon the thread sets the pendulum in a slight swing- `lng motion downwards until the thread has loosened again, whereupon the pendulum swings upwards4 again. The 'same occurvrence takes place when starting the machine` a greater stress then acting temporarily upon the thread owing to the state of inertia of the thread holder. Instead of the arrangement described, the journals of the thread holder could, for instance, rest on pili, lows supported by springs.

. coned ends 'arranged to engage the cones on the driven shaft and .the alined frictionV cones.

2. In awinding machine, a'driving shaft having a spool-engaging end, an alined,

spring-urgedvbearing for the opposite end of a spool, an angle lever having one en d arrangedto engage the spool endl at the driv-v ing shaft, a second angle lever having one arm arranged' to engaged the second arm of the first angle lever and'its other arm arranged adjacent the path of the thread being Wound, whereby when said thread hangsand does not evenlyunwind, the' angle levers are operated to release the driving connection between the driving shaft and spool.

.3. In a winding machine, a driven shaft having a conical socket at its end, an alined shaft having a like socket,I a spring to urge the latter socket toward the former socket and means for engaging a bobbin end to relieve the driving friction of the former driven socket upon undue thread tension.

In testimony that I claim the foregoing as my invention, I have signed my name.
