2 Claims.
This invention relates to travelers for twister rings such as are used in the textile industry on spinning or twisting frames.
Travelers of the character mentioned usually consist of an ear-shaped metal strip that is loosely mounted upon an axially reciprocable twister ring, the latter circumscribing a rotating spool or bobbin. The traveler serves as a guide for yarn that is drawn onto the bobbin or spool from a creel of said yarn, the rotation of the bobbin causing orbital movement of the traveler about the twister ring whereby twist is imparted to the yarn. The traveler is so constructed and arranged that the yarn, in passing through the traveler, is diverted at an angle upon engagement with the traveler, and diverted at another angle in passing from the traveler to the bobbin, said angular turns producing a snubbing effect upon the yarn and imparting a tension thereto. In travelers heretofore provided, this snubbing effect is greatest when the bobbin is nearly empty,
due to the angle at which the yarn leaves the traveler, and thus produces a relatively great tension in the yarn and also tends to twist the traveler and cause greater drag thereof due to cramping of the traveler against the ring, thus aggravating an already undesirable condition. This effect is the reverse of the effect desired, namely, that any increase in tension in the yarn should be toward the full spool or bobbin.
The chief object of the invention is to wind spools or bobbins of yarn in such a manner that the high tension low stretch convolutions of yarn on the inside of the spools and the low tension high stretch convolutions on the outside thereof are more nearly equalized. A more specific object is to provide a traveler of such construction as to achieve the foregoing object. A further object is to provide a traveler of such construction as to have a neutral effect as regards difierential tension in the convolutions of yarn on the spool. Other objects will be manifest.

Figure 14 is a plan view of the structure shown in Figures 12 and 13.
Referring to Figures 1 to 4 of the drawings, M3 is a portion of the frame of a twisting machine, 3 l is one of a series of rotatable bobbins thereon, i2 is a transmission belt for driving the bobbin l i, and i3 is ahorizontally disposed, vertically reciprocablc ring plate that carries a series of twister rings, such as the twister ring M, the latter being arranged in circumscribing relation to the bobbin H. As shown in Figure 1, the ring :4. is mounted in the ring plate E3 in such a manner that the top and bottom edges of the ring are spaced from said plate, and loosely mounted upon said ring in the usual manner is a generally ear-shaped traveler l5 that embraces the respective peripheral edges of the ring, and travels oircumferentially of the ring as the bobbin H draws yarn onto itself by reason of being rotated by belt 52. Said yarn, designated 16, is drawn from a creel (not shown), and passes through a wire eye ll disposed above and coaxially of the bobbin, and therebeyond passes into engagement with the traveler i5 which angularly diverts the yarn toward the bobbin.
As best shown in Figures 3 and 4, the traveler [5 consists of a metal strip shaped as usual so as to embrace the ring M from the inner periph ery thereof. Upon the top of the traveler is mounted a short tubular eye or horn l5a that is welded or otherwise secured thereto. The axis of the horn [5a lies in and parallel to the plane of the traveler, and is disposed radially with relation to the axis of the bobbin H. The arrangement is such that the yarn H5 in passing into the horn makes a right angle turn, but in passing from the horn to the bobbin II it makes but a slight angular turn when the spool is substantially empty, as indicated in broken lines in Figure 2. The latter angle, however, becomes more pronounced (less obtuse) as the diameter of the bobbin increases due to the yarn wound thereon, as shown in full lines in Figure 2, with the result that the greatest snubbing effect is produced on the outer convolutions of yarn on the bobbin, and consequently greater tension imparted thereto. This condition is the reverse of that which obtains. when travelers of prior construction are used, and is considered more desirable.
The embodiment of the invention shown at IS in Figures 5, 6. and '7 consists of a single strip of metal that is suitably bent and doubled to provide an ear-shaped structure that is mountable upon a twister ring in the usual manner, one end of the strip, at the top of the structure, being bent into a loop or eye I9a that constitutes a yarn guide, said eye being open at 20 at one side to permit threading of yarn therethrough when no yarn-end is available. The axis of eye l9a is parallel to the plane of the traveler, and also is parallel to the axis of the bobbin with which it is associated. The arrangement is such that the yarn in passing through the eye l9a makes a single right angle turn and passes from said turn directly to the bobbin, and this is so under all conditions of the bobbin, whether substantially empty as shown in broken lines in Figure 8, or substantially full as shown in full lines therein. Thus the snubbing eifect of this embodiment of the invention is substantially the minimum that can be provided and that part of the yarn-tension effected thereby is uniform throughout all the convolutions of yarn on the bobbin.
The embodiment of the invention shown at 22, Figures 9, 10 and 11 consists of a relatively wide metal strip or plate that has its upper and lower end portions curved toward each other so as to define a general ear shape adapted to engage a twister ring in the usual manner. The medial portion of the structure 22 is formed with a relatively wide integral tongue that is reversely bent to form an elongate horn 22a that is open along one side as shown at 23, Figure 11. The horn 22a serves as a guide to angularly divert yarn coming from a creel toward a rotating bobbin, the yarn making a single right angle turn as it does in the embodiment shown in Figures 5 to 8.
The horn 22a, however, is longer than the eye Mia, and hence exerts greater snubbing effect upon the yarn than the latter, due to greater friction, with resultant increase in tension in the yarn, which part of tension due to snubbing is uniform throughout the windings of the bobbin.
The embodiment of the invention shown at 25, Figures 12, 13 and 14 consists of a single strip of metal which originally is angular in shape, and is so bent as to provide a generally ear-shaped structure with a generally tubular yarn-guide 25a on one side thereof. Said guide is open along one side, as indicated at 26 to permit the insertion of yarn in the guide when no loose yarn-end is available. This traveler operates in the same manner as that shown in Figures 9 to 11 and exercises substantially the same snubbing effect on the yarn.
The several travelers described make it possible to obtain substantially determinate tension in the wound yarn, whether there is a difierential tension in the various convolutions on the spool, or in those cases where the tension is uniform throughout.
Other modifications may be resorted to without departing from the spirit of the invention or the scope of the appended claims.
What is claimed is:
1. A traveler for twister rings, said traveler comprising a member having hooked ends adapted slidingly to engage a twister ring, and a generally tubular eyelet thereon constructed and arranged to extend radially inwardly of the main body of said traveler when in operation.
2. A traveler for twister rings, said traveler comprising a body portion having hooked ends for engagement with the twister ring, said body portion being constructed and arranged substantially parallel to the axis of the twister ring, and a tubular yarn-guide adapted solely to guide yarn onto a rotating bobbin, said yarn guide extending radially inwardly of the body portion, and being disposed on an axis parallel to that of the bobbin so as to cause said yarn to make a single angular turn in passing to the bobbin, which turn is of a constant angle under all conditions of fullness of the bobbin.
