- application mea February 1o, 1926.v serial m. 87,230.

This invention relates to new and useful improvements in yarn windings, and partlcula-rly to improvements on the article and method described and claimed in my Patent No. 1,572,157, and my copendingapplication Serial No. 62,575, filed October 15, 1925.

In accordance with the method described in said patent a groove or depression. is formed in the yarn 4 winding byv bearlng with a stationary tool afrainst the yarn while it is being wound on the core, the purpose of the depression being to afford a suitable location for knots in the yarn.'

In accordance with the method forming the subject matter of the present invention,

the necessity o f providing such special tool is avoided by varying the tension on thel yarn during a predetermined stage of the winding operation. The tension being increased or decreased when the yarn is being wound on a certain section of the core or cone, the yarn lengths within that section will be wound tighter and will therefore lie below the level of the balance of the yarn within the same layer. Thisincrease or decrease inv the tensioning may be most expeditiously 4obtained by varying the position of the standard yarn guide provided on cone winding machine. Furthermore, the depression may be accentuated or, to a certain extent,` produced solely by bearing with the yarn guide against that portion of the yarn which it is desired to depress.

While the depression in the yarn may be effected with the usual type of cone, I have found that a deeper depression'may be obtained if a core of .the type described in my said copendingapplication is used. Instead -of forming a narrow groove or depression in the paper cone or other core, a wide groove or depression is formed in this core, preferably". extending all the way to the apex of the ore. It is easier thus to depress a paper cone andfurthermore, a wider depression is obtained which will give the operator more space within which the knots vmay be placed.

In order more c early to set -forth the nature of the present invention I shall describe a preferred embodiment thereof. It should be understood, however, that yarn windings of the nature described and claimed in my said patent may be produced by a number of-other -methods and also that.

the details of the mechanism herein disclosed may be varied within a wide range without departing from the spirit of the invention.

In the drawings, Fig. 1 1s a front elevay tion of as much of a cone winding machine as is necessary for a clear understanding of the invention; y

Fig. 2 is a side elevation of the machine; Figs. 3 to 7 illustrate modifications of the thread guide control, Figs. 3-5 being horizontal cross-sections and Figs. 6 and 7 front and rear views, respectively, of the carriage. Fig. 8 is an elevation of a partly woun'd cone; and v Fig. 9 is an elevation of a modified form of a partly wound cone.

A paper cone 1 having a corrugated surface is clamped in the usual manner on the cone holder 2 of a windingmachine. Near its apex the surface of the cone is narrowed as indicated at 3 (Fig. 8). By means ofa lever 4 the cone 1 is clamped in place and rotated through a shaft 5 which in turn is driven by the usual driving means including a belt 6. A thread of yarn 7 is fed to the cone from a supply 8 through a suitable tension controlling mechanism 9. The yarn 7 then passes through a V-shaped groove 10 provided in the upper part of a' porcelain button 11 and thence is wound directly on the cone 1 The porcelain button 11 is carried at the upper end of an arm 12 ofresilient material. The arm 12 is fastened to a rod 13 which is mounted in the lower part ofa carriage 14 in a manner to permit yits travel back and forth in a horizontal direction. Reciprocatory motion is imparted to rod 13 by means of a shaft 15 carrying a Acam 16l and suitably geared to the driving motor. Since the details of this construction are well known in the art, their full description and illustration will be dispensed with. The carriage,v 14 is provided with a weighted rotatably mounted on the cam housing 19. The carriage 14`may be rotated around the pivot point constituted by 18 and thus moved to and from 'the cone 1. By means of acspring 20, also mounted on the cam housing and bearing against the weighted end 21 of thelever 17, the carriage 14 will lbe maintained in any position into which it may be moved by hand. However, the

arm 17 having'a hub 18 which is y spring permits the carriage 14 gradually to move away from the cone 1n the customary manner as the winding thereon becomes thicker.

By rotating the carriage towards the cone lithe porcelain button 11 is carried with it. Since the carriage has a fixed pivot point, the rotation towards the cone will result in raising it with lrespect to the cone. The raising of the button with respect to the cone will increase the tension of the yarn 7 fed through the groove 10. The spring arm 12 is so tensioned that it firmly lies against the carriage 14 and the thead is guided in such a manner that it will be wound at a predetermined tension on the cone 1 back and forth over a certain area thereof. As

` best shownv in Fig. 8, during the operation of themachine the button 11 being held against a carriage 14, does not quite touch the yarn winding on the cone 1 and, up to a certain point, remains always in the same position with respect to the cone. However, when the button 11 reaches a point opposite the depressed apex 3 of the cone, it will be moved towards the cone and therefore slight- -ly raised with respect to the position it occupies during the balance of its travel. This l' is accomplished owing to the provision of a steel spring 22 riveted at 23 to the carriage 14. The spring is so bent that the spring arms 12 carrying the buttonwill glide on top of, this spring and will be held by it away from the carriage and pressed against the cone.

Instead of this arrangement, any number of other arrangements such as the ones 1lvlustrated in Figs. 3 to 7 may be provided.- In

Fig. 3 the carriage 14 is shown as having a raised cam-like end 23 on which the arms 12 may ride. In the arrangement shown in Fig. 4 a bent spring 24 is fastened to the free end of the carriage 14, the end ofthe spring lying within a notch 25 provided in the carriage. Invthe arrangement shown in Fig. 5, a suitably bent wire26 is mounted on `the end of the carriage. In accordance with the arrangement shown in Fig. 6, instead of mounting a spring like 22 on the carriage 14, a leaf spring 30 is fastened with one end to the rear of arm 12. The free end of spring 30 bears against the carriage 14 and tends to push the guide towards the cone. However, such forward movement of the guide is limited by a rod 31 mounted on the carriage 32. The yarn guide reciprocates between'rod 31 and carriage 14, and when it reaches near the apex of the cone where the depression is to be formed, it follows an outwardly bulging pari; `33 of the rod and` thus app-roaches the cone and is raised with respect thereto. In the modification illustrated inFig. ,7, that part ofthe carriage 14 which is opposite the depressed apex of the cone is cut away as indicated at'34. A

.wire frame 35 is fastened to the rear of the carriage at 36 to afford a friction surface for the yarn guide. A spring 37 is mounted on the carriage 14 by means of a bolt 38 which projects through a longitudinaly slot 39 in the spring so as to permit the longitudinal adjustment of the latter. The forward,- ly bent end`40 of spring 37 projectsin front of the opening'i34 and overlaps the end of a spring 41 mounted on the front of the car.- riage 14 :xt-42. The bulge in spring 40 will control the, forward movement of the guide during its reciprocatory movement. By varying the 4adjustment of spring 37, the width of the depression in the yarn winding as well as the pressure on the guide may be controlled to suit operating conditions.-

Owing to thec fact that while the guide button 11 is travelling back and forth opposite the depressed end 3 of the cone the yarn 7 is wound at a greater tension than during the balance of the reciprocatory movement, that portion of each layer of the yarn which overlies the depressed end 3 of the cone will be maintained in alower level than the balance of the layer. The depression of the yarn winding within this area is accentuated' by the depression in the lpaper cone and also by the contact of the button 11 with'the yarn "winding However, as shown in Fig. 7, the

required depression may be obtained with a cone having a level surface and, of course, other means may be employed for varying the yarn tensioning.

It will be obvious to those skilled in the art that the width, depth or position of the depressed or grooved winding area may be varied, to suit operating requirements vand 'that the other features of the machine and the yarn while it is being wound on a certain section of thecore whereby the yarn winding concentric with said certain section will be depressed with respect to the balance ofthe winding, and placing knots withinl the depressed section of the yarn winding'.
