METHOD-F AND APPARATUS FOR WINDING AND WARPING.

Application enem is, 1925. Serial No. 30,710.

My invention relates to im rovements 1n theart of manufacturing texti es; more particularly, to the stage of taking threads from spools on a creel and winding and waignng them. I wind the threads, as coming rom the spools on the creel, in a novel way onto spooling drums; then I assemble these drums on a beam; the essential novelty of my nvention is my method of winding-a plurality of threads in layer fashion, feeding eac thread across the spool, so that each and all threads are fed from one si e to the other of the width of the spool in succession; and the objects of my improvements are, first, to eliminate the large reel on which in the present art the threads are wound coming from the creel'and from which they are unwound onto the beam; second, to eliminate the spacious and voluminous appliances required for the beaming andto accelerate the whole operations by" subdividing the beam :into sections and winding these sections at high speed separately, directly from the creel; third, to eliminate a great deal of the time of the operator who in the present art has to watch all consecutive steps very carefully; fourth, to wind the beam sections in compact fashion, by having the actual number of threadsflyin on top of each other. at each point of the %eam, the same number each time; fifth, to wind a width of threads and have them cross each other to eliminate tangling and the use of paper for keeping. them apart.

I attain these objects by the procedure illustrated in the accompanied drawings, in

which- Figure 1 is a view of my spooling device looking at it in the direction of the main shaft, with parts omitted which do not add to the disclosure. Figure 2 shows the beam with spools arranged on it. Figure 3 shows a clamping nut for the beam. Figures 4 and 5 show two views of the dent s used in the spooling device for accuratelyfeeding the threads. Figure 6 is a side view of the spooling device on which the upper half of the circular parts is shown in the sectional view. The tension arrangement is omitted. Figure 7 shows the top view of that tension arrangement.

Similar numerals refer to similar parts throughout the several views.

The table or plate 9 with an extension 10 on one side, which holds a tensional arrangem e wi an upr ght e tens on rac et 11' which serves to hold theshaft and with a dove-tail extension 12, constitutes the frame on which the spooling device'is assembled.

A shaft 13 is solidly mounted in the bracket 11 and has .an oil cup 14 on the end by means of which, through the hole 15 in the shaft, the various parts rotating on that shaft are lubricated. Collars 1 6 and 17 and bracket 18 are mounted solidly on that shaft and serve as thrusts for the various parts rotating on the shaft. Part 19 is a cam which rotates on that shaft, and has, with two high spots and two 10w spots 20, a face shaped'to give an even rise and drop between the low and high points respectively. On the back of the cam on its circumference are ratchet teeth 21 which mesh with a pawl 22 mounted on stud 23 on the base 9. A cylindrical extension 24 on the back of the cam serves as a-pulley for a belt drive. That extension is next to a loose pulley 25 rotating freely on shaft 13 between the face on the bracket 11 and collar 16, and which together with the extension 24 represents the idler and driver pulley to operate the machine.

On the hub of the cam 20 a spur gear 26 is solidly mounted. It meshes into a pinion .27 which rotates on a stud 28 whichis fastened to the solid bracket 18. Part 29 rotates on shaft 13 and on one side has an extension 30 which serves 'as a mandrel onto which spool 31 is slipped. Another cylindrical extension '32 extends into the interior of body. It points in the direction'of rotation of the machine and serves to hook the threads onto it.

On the dove-tail extension 12 rides a slide 37, with a hub 38 on its lower side. Through a ta ped hole in that hub passed screw 39 whic freely turns inbearings-in the flanges on the ends of the dove-tail extension 12 of the base 9. The end thrust of the screw 39 is taken up by collar 40. and handle 41,

, which are ositioned at the ends of the dovetail extens1on12. Operation of handle 41 w l heiefwe feed the slide'37 and, integral parts toward and away from the winding drum. This motion is limited by the circumferential dimensions of the cam.

Vertical extensions 42 on'both sides of the slide are shaped so as to be concentric to the main shaft in acertain position of the slide. Eye bolts 43 in these extensions clamp the dents to the concave cylindrical surfaces of the extensions by means of the reds 44 and the blocks 45. These blocks together with the dents 46 are constructed according to the fashion of reeds, but the dents 46 are not solidly mounted in these blocks but are free to slide in them, and against rods 44. The spacing of the sliding dents is obtained in exactly the same fashion in which dents are spaced in a reed, i. e. the individual coils of a spring keep them apart; the back half of each turn of the coil is cast into the block 45. 47 shows the half coil extending between the dents. The shape of the dents is shown in Figures 4 and 5. One end is bent onto itself at 48 and thus represents a face which rides against the cam 19. In the center of the dents are holes 49 shaped in the fashion of the eyes in heddles. Each other end of the dent has recesses 50 on both sides and a lug 51 on the very end. On alternating dents these lugs extend in opposite directions as shown in Figure 6. The

recess 50 may be made at a slightly obtuse angle as shown in Figure 0, onto which rubber bands may be hooked, the other end of the rubber bands to be hooked on pins 52. On parts 42, the tension of these rubber bands holds the dents onto the faceof the cam. Since the dents are very light and flexible the last ones on each end have been replaced byheavir bars 53 which serve to support the whole unit of dents on both ends. These bars may be provided on one end with pins 54 on which to connectthe rubber band.

The dents taken as a whole form the section of a hollow cylinder. Lugs 51 on alternate dents protrude from the outside of the cylinder. ture of the outside of the cylinder,'this rod strikes against all these protruding lugs 51 when I slide it along that cylinder. Letting such a rod strike these lugs, and by means of it pulling the dents which have these lugs away from the cam, I pull the threads in the respective dents in the same I direction to cross under the adjacent threads. By this operation, I make the cross in winding the spools, i. e., I provide a mark of identification at a certain point of the Winding on the spool.

On extension 10 of the base are set two upright studs 55 on which rollers 56 are rotatably mounted. Another roller 57 mounted to rotate on a shaft 58 in a swinging bracket 59 fits in between the other rollers 56. The swinging bracket 59 rotates around shaft 60 which is also mounted in the exten- If I bend a rod to fit the curvasion 10 of the base. The swinging bracket 59 is arranged in such a way that it freely swings away from the rollers 56 but in its motion to those rollers, a stop maintains a spaced relationship between rollers 56 and 57. A steel band passes around the lower end of rollers 56 and 57 and has a stud extension 63 with a wing nut 64 on its threaded end. This stud extension with the wing nut may be hooked onto lugs 65 extending from the swinging bracket. By tightening up the wing nut 64, the steel band 61 is pulled tightly around the rollers 56 and 57 and its friction against those rollers serves to retard their free rotation. The spools 31 are shown arranged ona beam 66 in Figure 2. They are slipped onto the beam against a flange 67. On one end the shaft 68 has a thread 69 onto which fits the nut 70 shown in'Figure 3. The hollow cup 71 fits over the circumference of beam 66 and clamps the spools 31 against flange 67 when the nut 70 is put on to the screw part 69 of shaft 68.

I carry out my invention as follows:

In Figure 1 the strands of thread are shown coming on the left from the creel. From there they pass through the tension device. i. e. they pass between the rollers 56 and 57. To feed them into the tension device, I unhook the brake band 61 by loosening up on nut 64 and unhooking that nut with the bolt 63 from lugs 65, and swing tensioning device I take singly or in small numbers and feed them through the eyes of the dents 46, pull them through onto the spool 31and by a knot or a simple loop, hook them onto the lip 36 on that spool.

I am now ready to do the spooling. By means of a belt shift I shift thedriving belt from the loose pulley 25 to 24thereby starting up the machine. The cam turns in counter-clockwise direction and'by means of the pinion 27, the internal gear 33 and with it the spools are driven in clockwise direction. The rise of my cam is equal to the width of my spool and the eyes in the dents sliding on the cam moving back and forth feed across the width of the spool. The

threads passing through the eyes of the dents "spot at which the band is laying spread out on the spool, after each turn of the spool. I

hereby obtain an even .number of layers of threads on the circumference of the spool as of the dents, I have provided a cross feed on the slide which carries the dents. By operating that cross feed I bring the slide close to the spool and as the material spools onto the spool and forms heavier layers, I feed the slide away from the spool to give clearance for the material as it piles up. The drawing shows the tension device arranged offset towards the cam to the left of the spool (see out 8 in Fig. 6). The threads, tensioning between the spool and the tension device, will therefore pull the dents against the cam.

If that tension is not found suflicient to hold the dents a ainst the cam, I additionally hook rubber bands onto the dents which pull them tightly against the face of the cam. For the-bars 53 on the ends of the row of dents, I use such rubber bands all the time because there is no thread going through thcisebars which might exert the desired p I have rovided a ratchet on the back of the cam into which meshes the pawl 22 mounted on the,base, to prevent the spool head from being pulled back by the tension of the thread when the machine is brought to a stop when the belt is slipped onto the loose pulley.
