Patented Jan. 1, 1952 I YARN TENSIONING DEVICE Thomas K. Rea, Gastonia, N. 0., assignor to Cooker Machine and Foundry Company, Gastonia, N. 0., a corporation oi North Carolina Application March 10, 1949, Serial No. 80,692 8 Claims. (01.242-454) This invention relates to yarn tensioning devices useful in connection with textile machinery or apparatus, particularly with creels incident to beam, warping and similar operations.
. My invention has for its chief aim to provide justed to change the imposed degree of tension on the yarn over a wide range to suit any or all requirements which are likely to be. met with in practice.
Another object is to provide, in connection with the yarn tensioning device having the foregoing attributes, adjustable means for restraining the yarn against ballooning as it comes from the supply source andthereby preventing variation in the tension which it is desired to maintain.
Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein Fig. 1 shows the top plan view of a yarn tensioning device conveniently. embodying my invention.
Fig. 2 is a side elevation of the device.
Fig. 3 is a fragmentary view showing a portion of the device in bottom plan.
Fig. 4 is a fragmentary view in elevation looking as indicated by the angled arrows IVIV in Fig. 1.
Fig. 5 is a, section taken as indicated by the angled arrows V-V in Fig. 1.
Figs. 6, 7, 8, 9 and 10 are views like Fig. 1 showing various ways of threading the device.
From these illustrations, it will be noted that my improved yarn tensioning device comprises a member in the form of a bracket ii having a jaw l2 for engaging an upright or post P to support the device in horizontal position, the set screw indicated at l3 serving to secure the bracket at the desired elevation. The extremities I4 and I! of the racket l8 terminate in upright lugs 16 and I1 th inset yarn guide eyes It! and I8, and, as shown radiate substantially from an upstanding yarn directing stud 20 which is fixed Fulcrumed for adjustment about the stud 21 in the interval between the latter and the guide eye 18, is an arm 22 which is fashioned from relatively thin spring metal, and provided at its distal end with an upstanding yarn directing stud 23. The arm 22 is releasably held in with spot indentations 25 which are arranged in an are having its center of curvature in the axis of the fixed stud 28.
Impaled in superposed relation on the studs 28, 23 are pairs of discs 25, 21 and 28, 29 respectively, between which the yarn indicated by the letter Y is passed. It will be noted from Fig. 5 that the discs 26, 2'! and 28, 29 are dished in cross section, and that they are arranged with the flat surfaces of the individual pairs opposed to each other. .As further shown'in Fig. 5, the disc pairs 26, 21 and 28, 29 are held down by weight collars 38 and 3i which are rotatively free on the studs 28 and 23 respectively. Washers 32, 33 of felt or the like beneath the lower discs 21 and 28 of the respective pairs impose a certain amount of frictional'restraint to the turning of said disks as the yarn passes over them. At 35 is a third yarn directing stud, which rises from the extremity H of bracket ll adjacent the lug i8 and which is ofiset laterally somewhat in relation to the eye l8 as shown in Fig. 1.
For the purpose of controlling ballooning of the yarn Y enroute from'a source of supply (not shown) to the guide eye I8, I have provided a control element 36 whichmay be fashioned from wire as shown, with a yarn confining loop 31 and a shank 38, the latter terminating in a laterally offset elongate loop 39 (Fig. 3) arranged to be clamped to the bottom of the bracket extremity It by a nut 48 threaded onto the lower end of the stud 35. By virtue of this arrangement, the control element 36 can be adjusted to position its loop 31 at different distances from the guide eye l8 as may be necessary to properly hold the yarn in check.
In Fig. 1 the yarn Y enters the guide eye I 8 after having traveled through the loop 31 of the control element 36, and, on itsway to the guide eye 19, is diverted to first pass around the stud 35, and then about the studs 23 and 20 and between the disks 28, 29 and 26, 21 respectively on the latter studs, being thereby caused to traverse an angular path with consequent imposition oi a definite degree of tension upon it. If greater or lesser tension is desired, the angularity of the adjusted positions through engagement of the lower projecting end of the stud 23 selectively traverse path may be decreased or increased simply by shifting the arm 22 clockwise or anticlockwise about the stud 2| in a manner readily understood in Fig. 1.
If a constant tension of a predetermined degree is desired, the yarn is simply passed about the studs 35 and 28 only as shown in Fig. 6.
As another alternative, the yarn may be passed directly from the eye [8 to the stud 28, and then assures 3 about the stud II. with a possibility oi adiustment of the arm 22 for variation in the applied tension. Ag thevammarb pasae irom the's eye It directly to the stud 2.0 enroute the guide eye I! as mm. 8; orit maybe directly from the guide eye ll about th adjustableatuduonitswaytotheguideeye liasin Fig. 9.
Still another way or threading the yarn is shown in Fig. 10 where it is passed from the guide eye It, directed about fixed stud 35 then about the adjustable stud 23 before entering the s deeye ll.
From the foregoing it will thus be seen that my improved "yarn tensioning device can be threaded in various ways for imposition of different degrees of tension between wide ranges incident to delivery, and is therefore easily and quickly adaptable for use with all kinds of yarns of diiferent weights and deniers.
Having thus described my invention, I claim: 1 A yarn. tensioning device comprising a bracket with a fixed upstandingyam-directing stud, and a fixed yarnguide eye in spaced relation to the said stud; an arm of flat spring metal 'fulcrumed on the stud for capacity to be shifted in the interval between the stud and the guide eye, said arm -being spring biased toward,the
bracket; an upstanding yarn-directing stud anchored in the arm with its bottom end rounded and protruding; and a series'oi indentations in the support arranged in an arc concentric with the axis of the fixed stud for selective engagement by the bottom protruding end of the stud on the arm to hold the latter in adjusted positions.
2. A yarn tensioning device according to claim 1. further including pairs friction discs impaled about the respective studs between which the yarn is passed.
3. A yarn tensioning device according to claim 1, further comprising a fixed yam directing stud on the bracket adjacent the yarn guide eye and onset to one side of the plane common to the fixed stud and the guide eye.
4. A yarn tensioning device according to claim 1, further comprising a control element having a loop through which the yarn is passed on its way to the guide eye for restraining the yarn against ballooning; and means whereby said ele- 4 ment is secured to the bracket with capacity for adjustment of its loop toward or away from said guide eye.
5. A yarn tensioning device comprising a bracket with a pair of fixed yarn guide eyes disposed substantially at right angles to each other and substantially equally spaced from an outstanding fixed upstanding yarn-directing stud on the bracket; an arm offiat spring metal fulcrumed on the stud so as to be moved through the interval between the latter and the two guide eyes, said arm being spring biased toward the bracket; an upstanding yarn directing stud anchored in the arm with its bottom end rounded and protruding; and a series of indentations in the bracket arranged in an arc concentric with the axis of the fixed stud for selective engagementby the bottom protruding end of the stud on the arm to hold the latter in adjusted positions.
g 6. A yarn tensioning device according to claim 5, further including pairs of friction discs impaled upon the respective studs between which the yarn is passed.
7. A yarn tensioning device according to claim 5, further comprising a fixed outstanding yarn guide stud adiacent one of the yarn guide eyes on the support and offset to one side or the plane common to the first mentioned stud and the guide eye.
8. A yarn tensioning device according to claim 5, further comprising a control element with a loop disposed outward beyond one or .the guide eyes for restraining the yarn against ballooning on its way to such guide eye; and means whereby said control element is secured to the bracket with capacity for adjustment of its loop toward or away from the last mentioned guide eye.
