I The principal object of this invention is to provide the yarn-traversing means of any machine, as a winding machine, in which the yarn while being drawn lengthwise is traversed crosswise of itself with a slub-detector so cooperative with'the said traversing means that the cutting or forming of nicks in the detector as an incident of the travel of the yarn was effected has been regarded as impracticable because the traverse induced the cut-ting of nicksin the detecting edges of the slub-detector by thetravelling yarn and consequently V a whirl 4: and carrying the spool to receive the catching of the yarn in such nicksand its being therefore broken.
My inventionis not limited in its application to instances Where the yarn is actually.
traversed. It applies, as will be apparent, in any instance where the travelling yarn exerts pressure on thedetector tending to displace it crosswise of the yarn and so promotes the forming of the nicks.
In the drawings, 7 I
Fig; 1 shows in side elevation sufficient of a winding machine containing the invention to illustrate the latter;
"Fig. 2 is a plan thereof on a smaller scale; 7 Fig. 3 is a rear elevation of the traverse means and the slub detector; and
Fig. 4 a side elevation thereof, with said means partly in sect-ion.
The winding machine shown is of a well known type. 1 is its frame; 2 brackets there- 1n to'support the revoluble thread aperture, here a core 'on which the yarn a 18 wound, such core here comprlslng a spindle 3 having the windings; 6 a suitably rotated driving wheel on which the whirl l: rests and by "which the core is rotated; and 7 a yarn-traversingrail suitably reciprocated in the frame lengthwise of itself and crosswise of the yarn and having a yarn-guide 8 provided with a yarn-receiving notch 9. The core and wheel form the aforesaid means to draw the yarn lengthwise and the rail affords the aforesaid means to traverse the yarn crosswise.
A support in the form of a plate 10 is here secured to the back of the railto wit, the
side adjoining the core for the windingsbysc'rews 11, it being provided with slots 12 extending, and thus permitting adjustment of the support and'hence of the slub-detector carried by the'support, lengthwise of the rail. It may have a flange 13 to rest on the top of the rail and a pair of spaced stops 1 1. The
plate has a rearward projecting headed stud I or pivot 15 in the vertical plane of the notch 9' of the yarn guide 8.
The slub-detector is an elongated plate 16 having a notch 17in one end communicating with a slub-detecting slit 18 extending lengthwise of the plate. Nearer the notched than the other end of the plate is a bearing 19 formed as one end of a key-hole slot 2O adapted to receive the pivot 15; when'th'e slubdetector is thus supported on the pivot it hangs normally in the position of Fig; 3, with its notched end up, due to gravity acting on its longer lower end portion. It is, however, free to swing back and forth laterally, at least as far as thestops 14: will permit.
Operation: The detector in the example; illustrated is in effect a pendulum, sothat it tends to stand vertically. 'As the rail re-' ciprocates in traversing the yarn exerts presa sure on one side or the other of thedetector slit, according as said side is the relatively following one of the two. If the detector were rigidly mounted on the rail the frictional contact of the travelling yarn with such side would produce a nick therein, which sooner or later will catch and break the yarn. But according to my construction the detector yields to the yarn, andsuch yielding in itself delays the cutting of such nicks. But, in addition, the detectors"movement in yielding, because the detector ispivoted, is not only lateral but downward (thatis to say, crosswise of the yarn as well as of the traverse), whereby the yarn shifts its posi tion along the side of the slit against which it is caused to bear due to the displacement thereof by the rail. v this example the detectoris mounted on the rail; but that is obviously not indispensable.
In this example, further, andaccording to i a well known system characterizing winding machines of the; class shown, the traverse action on the yarn is from a plane cutting the spool centrally towardjeach end thereof;
wherefore as stated the detector yields to the yarn in the traverse of the rail in opposite directions from said plane. However, the
invention is not limited to'the-traverse motion imparted to the yarn and the conse- ,quent yielding of the detector being thus alternately in opposite directions, as the appended claimsindicate.
. Again, in t e x mp e he ab de ct s normallynrged (here by gravity) to a given ne it n; t t a a s s no ndispens It is further newto combine means to draw y rn leng hwis ifel me 1s. a r e theyarn crosswise of itself, and a slub de-,

', Having thus fullydeseribed my invention what I claim is: e
. 1. In combination, a support and a slub detector carried thereby and having an apere tnre to receive the yarn and normally held in a given position but yieldable therefrom on the support in opposite directions crosswise of and to the yarn whilethe latter is drawn lengthwise of itself.

3. Mechanism of the class described comprising means for drawingthe yarn length .wiseof itself, means for traversing the yarn crosswise of itself anda slub detector engaged by the yarn and forming an independently movablepart of said mechanism yieldable to theyarn in one direction of its traverse motion.
