WINDING DEVICE FOR LOOKS.

Application flled- July 5,

one has almbstrun out or when the yarn,

breaks.

Such looms are generally provided with replenishing mechanism, reduces the result that each ejected bobbm has remaining upon it more or less yarn. To be used again the yarn must be removed from, the bobbin. This may be done by hand or by the use of bobbin stripping machines of which there are several types.

The free end of the yarn on the ejected bobbin hasbeen cut or broken almost inyariably before it has run out through the 'eye, of the. shuttle, and attempts havebeen made, with more or less success, to trap this end, to retard it, or to catch. it in some way so that it can be automatically wound up and thus unwound from the ejected bobbin begoes into, or while it is in, the receiv- If this is done successfully, the use of bobbin stripping machinesor bobbin strippers is avoided, and each bobbin receiving can of the loom Wlll contain several timesas many bobbins cleared in this fashion as when between the roll and guide and it is difficult to remove it from the windin rollf When a smooth bobbin isemploye or where a spindle is used, as shown in my Patent No.

1,423,670, when the winding member is cleared it is necessary to catch new yarn around the smooth bobbin or spindle by hand in order to cause it to wind.

On the other hand, with a smooth bobbin, such as shown in another patent, or where a Y {.Jspindle is used, as shown in application filed by me' and, pending herewith, when the winding member'is cleared it is necessary to catch new yarn around the smooth bobbin 1921. Serial- 110.482,!16.

or spindle by hand in order to cause it to wind. This causes delay and is rather a troublesome operation for the reason that in order to be readily stripped, the bobbin or splndle should be smooth, and this very smoothness tends to permit the yarn to slip until the smooth surface is covered by enough yarn to catch the yarn from each bobbin thereafter ejected from the spindle. feeler mechanism which, together with the is ejected, and will hold it long enough to.

be caught by the finger and wound on the spindl T a By using such a finger, especially inconnectlon with a tapered spindle, I utilize the well known tendency of a belt to crawl along a conical pulley to the large end, and also utilize the fact that the shuttle eye when the bobbin is ejected is in its farthest position from the warp, andthat when the shuttle is picked and moves towards the warp, thus;

tending to clear itself from the tail of am from each ejected bobbin, it also ten s to carry that tail toward the warp. With a trap in the lay beam or other similar device which opens at each pick, gravity causes the yarn to swing toward the warp at the second pick. I'therefore prefer to locate my fin er catch at-the large end of a tapered spin le, such large endbeing nearest the loom frame and warp whereby both tendencies are utilized.

The spindle may be tapered and the finger parallel with its axis, or they may be arranged in any way whereby there is a short distance or month between the free end of the finger, or of each finger, and'the spindle, large enough for the yarn to enter, and facing in the direction from which the yarns tends to move.

In the drawings, Fig. 1 is a front elevation showing part of the breast beam. and lay beam of a magazine 100111 with my preferred form of device in position, parts being broken away to show the construction.

Fig. 2 is an elevation from the left of Fig. 1, with parts broken away and showing two positions of the lay beam.

Fig. 3 is a front elevation showing part of the la beam and winding member of a slightly ifi'erent form from Fig. 1, and a retarding member in place of a trap.

Fig. 4 is a front elevation enlarged, showing my preferred. form of winding member as illustrated in Fig. 1.

Fig. 5 is a detail in elevation showing a modifiedform of winding member.

Fig. 6 is a front elevation in detail showing another form of winding member, and

Figs. 7 and 8 are detail elevations showing still other forms of winding members.

In the drawings, A represents the-breast beam, L the lay, 10 a part of the frame, C

- the picker and 12 the magazine of a magazine loom of the Crompton & Knowles type. 9 represents a full bobbin in the magazine, 8 a full bobbin which has just been delivered into a shuttle, and B the bobbin from which the yarn 13 has almost been exhausted and which has been discharged from the shuttle, such as I), having an eye' 19.

20 represents the end of the tail of yarn 13 from the discharged bobbin B which, at the time indicated, still runs through shuttle eye 19 and out toward the warp along-the lay beam. I

Referring to Fig. 2, 21 and 22 represent the opposite walls of the passage 11 indicated in Fig. 1 in the l y beam L,,through which the em ty 0ralgiost empty bobbin, such as B, is ischarged from shuttle D. .6 is a sloping apron which directs the shuttle into the can K. v

In my preferred construct1-on,-I use a trap,

indicatedby T in Figs. 1 and 2,'located preferably on the lay beam in position to catch the loose end of the yarn on the ejected bobbin and to' hold it until said yarn is caught "by the catch onmy winding spindle or member and begins to be wound up thereby.

As shown, this trap comprises a spindle 30 carried in bearings 23 and 24 shown as attached to the outside of the lay beam on the side 22. The arms 31 and 32 extend at right angles to spindle 30, preferably so curving that the cross bar 33 which connects them will rest snugl up against the top part of the side 22 w en the .trap isclosed. Between this bearing and the side 22 is thus formed what I may call a trap bobbin passage. v j

The returning sprin 35 is attached at one end to spindle 30 an at the other end to bearing 23, and is so positioned that it tends to fold up the trap against the side 22 when not pushed open by the dagger 36. This dagger'36 is'connected at 37 to any stationa suitable hole 27 in the side 22 of the lay beam. The dagger and hole are so positiond that the dagger will strike 31 when the lay beam has almost come up to the nearest point to the breast beam and immediately before the empty bobbin is discharged. The dagger 36 may be rigid or may be a metal rod which can readily be bent so as to adjust the parts correctly.

Preferably, the dagger strikes at a point on the trap armpretty well down toward the spindle so that the cross bar 33 will move rapidly over to the side 21 and allow the bobbin to be ejected between it and side 22 through the trap bobbin passage. The trap is thus opened as the bobbin B is discharged, but is closed instantly thereafter whereby, before or at the second pick when the trap is again opened, the yarn 13 slips over to the left to the position shown by the dotted lines in Fig. l.

As soon as the tail end is caught, the bobbin being still in flight will be spun around, unwinding to a certain extent as it drops into the can.

- With this device I locate behind the path of the bobbin as it is ejected from the shuttle, as clearly shown by the dotted lines in Fig. 2, a spindle S revoluble in bearings 14 attached to frame 10 which carries a whirl 16 which is rapidly revoluble by a belt 17, as clearly shown in Fig. 4.

Preferably, this spindle S tapers down from its large end 41 near the whirl to a small end 40, and preferably the whirl is protected at the top by a guard 46 and at the bottom by a guard '47 so that the yarn cannot become entangled therewith. As

by the spring 35 as the lay beam'recedes a short spring catch 42 fixed to the large end 41 and having its free end 43 slightly turned outward, and the-long latch 44 fixed at the end 41 having its free end 45 turned outward, both being positioned substantially longitudinally from the large end of the spindle.

With this tapered construction, as shown in Fig. 2, as the lay beam L moves back and forth toward the breast beam and the trap opens and closes, the tail of the yarn 13 between the shuttle S and trap T is loosened and tightened, and for this reason crawls from the small end 40 of the spindle toward the large end 41 until it is caught by one of the spring catch fingers 42 or 44, when it immediately becomes entangled and is rapidly wound u If one spring finger does not catch it, t e other will, and as it winds these are pressed in toward the spindle. With thisconstruction, after sufiicientyarn has been wound, as indicated by the dotted lines in Fig. 4, it can be readily stripped off toward the small end of the spindle, the taper of the spindle permitting this to be easily done.

While I prefer to use a positive action trap, I may, as shown in Fi 3, use a clearer for retarding the tail of t e yarn, such as shown in patent to Moore, bobbin stripper for weft replenishing looms, dated June 16, 1908, No. 890,865. In Fig. 3, the trap is omitted and the spindle S 18 shown as having one spring catch 82 instead of two, and

. 5 represents a rough piece of cloth or card clothing intended to retard or catch the tail end 20 of the yarn .13 from bobbin B. As the yarn floats or is carried over from the dotted position to the full position shown at 3 and strikes the clearer 5, it assists in retarding the end until. it is caught by the winding member-S.

y I find, however, that my pe culiar form of winding member will work without the trap .if the clearer cloth 5 is entirely omitted or fails to function.

Various modifications of my winding member may be used with more or less success, such as those shown in Figs. 5, 6,.7 and 8. y

In Fig. 5, S represents atapered spindle revoluble by a whirl 16 having at the large end a disc fromwhich projects a rigid finger 51 positioned longitudinally from that end of the spindle.

In Fig. 6, the shaft carries driving whirl 61, a protecting disc 62 and thimble 63, in which is atapered hole 64 to receive the small tapered. end 65 of a winding'member P which, preferably, is of metal and has bent around from the large freeend 66 a' rigid finger 67 longitudinally positioned from the largeend thereof. When suificient yarn is wound upon this device, it can be pulled out from the hole 64, stripped from the end 65, and replaced.

, In Fig. 7, the shaft 70 forms part of spindle 7 2 of uniformdiameter throughout, revoluble b a whirl 71-. At the-free end 77 is a catch 5 having an enlarged portion with a hole 73 which allows it to be slipped over the end 77 and held in place by a set screw 74. This member has a catch finger 76 which extends substantially horizontally from the free end, preferably "'at'a .slight angle so asto tend to throw the yarn down toward the middle of the spindle. To strip this device, member is removedand the yarn stripped by hand.

In Fig. 8, the spindle S, whirl 16 and guard 46 will be the same as shown in Fig. 4, except that there are no spring fingers on the spindle. In place thereof a wooden bobbin H having a spring finger 79 attached at one end is forced on the spindle and revolves as part thereof until filled with yarn,

when it can be removed and stripped and replaced by another.

It is obvious that instead of one or two fingers more might be used, and that these might be shorter or longer and either rigid or elastic. I find, however, that two, such as between it and the surface of the spindle orv bobbin and narrows. down in a V shape so that yarnentering will wedge therein.

Still more specifically, I claim a spring or elastic finger as being entirely new. I claim:

1.
