3 AD OR YARN TENSION DEVICE C Application filed October 25, 1915. Serial No. 57.769.

To all whom it may concern Be it known that we, FRANK Asrrwoirrn HOLT, a subject of the King of the United Kingdom of Great Eritain and Ireland, and resident oi Noon Sun House, Nhitworth Road, Rochdale, in the county of Lancaster, England, and Gnnvnnon lirnsiraw, a sub ect of the King of the Unit-ed Kingdom of Great Britain and Ireland, and resident of 62 Market street, Whitworth, in county of Lancaster, England, have invented new and use ful Improvements in T iread or Yarn Tension Devices and Clearers, of which the fol lowing is a specification.

This invention relates to the kind of ap paratus for applying or tension toer cleaning yarn, thread, cord, twine or the like in which the material to be subjected to tension and cleaned is made to pass beneath and to revolve a disk or the like by being made to pass-between such disk or the like and a support beneath it.

This invention consists in a :form of apparatus of the said kind more eiiicient and convenient than those heretofore provided in enabling the yarns, threads, cords, twine or the like subjected to drag or tension or cleaning to be wound at-any speed requisite in any case under proper drag or tension and cleaned without being subjected to excessive tension and consists further in advantageous expedients hereinafter to be indicated, hindering or checking such disks or like revoluble parts from being revolved too freely and obviating the too frequent or too protracted rise of disks or the like made to bear on yarn,

Hereinafter for simplicity the word yarn will be used instead of yarn, thread, cord, twine or the like and the word disk will be used in the description and the claims to mean a disk, cup or other like part to be revolved by contact with yarn, thread, cord,

twine or the like.

This invention is illustrated in the accompanying drawings by exemplifications. Figures 1 and 2 are respectively a side elevation partly in vertical section and a plan and Figs. 9 and 10 a vertical section and plan of parts detached, illustrating one form of tension applying or yarn cleaning apparatus provided according to this invention and other forms are illustrated in Figs. 3-8and l1l8 both inclusive in which Figs. .6, l2, and let are plan views, Figs 15 and 17 are plan views of the upper disks inverted and the rest are all vertical sections or vertical sections partly in side elevation to show parts more clearly and indicating how some of the expedients may be applied in forms of tension device other than that shown by Figs. 1 and 2-.

Figs. 1 and2 serve also as an illustration of one way in which the parts provided according to this invention may be mounted for use in the machines to which they are to be applied.

in the apparatus illustrated in Figs. 1 and 2, a disk j is mounted around and supported by the apex of a fixed pivot or projection carried by afixed part f and is provided with a non-circular disk a mounted upon it so that yarn maybe led between the disks y and a. The disk j is provided with an upwardly extending projection p in which the hole to receive the pivot or projection 71;

is formed and around which the disk a is placed.

may be made with a projection shaped and.

fitted to engage a corresponding space in the other of shape and size to permit the one disk to move athwart the axes of revolution relatively to the other while both disks are 21] ways compelled to revolve turn for turn together.

Further according to this invention a fixed projection or abutment of any kind may be placed near the disks so that one or each disk may swing against such projection or abutment in the lateral movement of such disk. The projection or abutment may be made to extend over the disks to hinder or prevent them or the upper one from being accidentally dislodged from their or its proper working position and may be shaped so that the upper disk may be placed upon the projection or abutment before or while the lower disk is being put into or removed from its ordinary Working position.

in Figs. 9 and 10, the sleeve of the disk j is shown as square in the upper part 1 and circular, to simplify manufacture, in the part 2 below the square part and the disk a and of such width that the disk a will be turned with the disk j and long enough to allow the disk at to be moved diametrlcally upon the disk j., in Figs, 1, 2 and 9, a projection w, omitted from Fig. 10, for parts below it to be shown, is illustrated as secured to the fixed part f and extending upward therefrom near the sides of the disks j and a.

In Figs. 1 and 9., the pivot or projection is and the hole in the sleeve 32 to receive the pivot or projection it are indicated as cylindrical and fitting one another.

The fixed part f forms part of a bracket A which is provided with a hole to receive a rod B and a set screw A by which it is secured upon such rod B.

The bracket A is shaped so as to afford a notch I to act as a guide for yarn and also to aflord a fence J extending around part of the circumference of the disk j in order that yarn may be hindered from passing below the disk 7'. A wire curl K screwed into the bracket A is provided as a guide for yarn at the side of the disk j away from the notch I. The bracket A and curl K form no part of this invention.

Yarn drawn through the notch I and the curl K or in the opposite direction will pass between the disks and a and revolve them and the friction of the yarn against the disks causes drag or tension to be applied to the yarn and effects the removal of loose matter from the yarn so cleaning it. The disk 7' with a sleeve p prevents dust from reaching the bearing of the disk 9' on the pivot It. Should the yarn passing beneaththe disk (1 revolve the'disks a and j at a speed sufiicient to throw the disk (1 out at one side it will arrive against the projection to and be checked in its revolution and thus the disks '1' and a will be prevented from revolving too rapidly and allowing yarn to pass too freely between them. The projection -'w is provided/with an arm extending over the sleeve p of the disk j so as to prevent the disks from being accidentally removed from the pivot k.

The projection w is made so that it may be removed from the part f in any convenient manner when it is necessary or desirable to remove the disk a or disk j from the pivot For example the projection w may be screwed into a screw threaded hole in the part f, as shownin Fig. 9.

The hole in the disk 1' may be made if desirable in any case a little larger than the pivot or projection 72 so that the disk may move or wabble laterally in relation to and bind more readily upon the pivot or projection so as to be checked in its revolution or the pivot is or the hole in the disk 7' to receive it or both of-them may be made taper as for example in modes analogous to those hereinafter demribed in reference to Figs. 7 and 8. The provision for lateral movement or wabbling is preferably made 32 may have less about which it or'they is or are to be made,

to revolve may be provided to be applied in or on the upper disk whether or not the upper disk or the lower disk or both is or are'made unsymmetrical or out of balance.

Making a disk unsymmetrical or out of balance with relation to its axis of rotation or non-circular or weighting it with a weight or washer which is unsymmetrical or out of balance with relation to its axis of rotation insures that any incipient increase in speed of revolution of the disk shall be accompanied by an increased tendency of the disk to lateral movement causing, according to the construction adopted in any case, lateral movement of the disk or increased pressure of the disk against its support or, in the case of adisk mounted on another disk, lateral movement of one or other disk or both or increased pressure of the one or other disk or both against its or their support or arrival of the disk or one or other disk against the stop if there be any provided for checking it from revolving and thus in any case the incipient tendency of the disk or disks tounduly rapid revolution for example an unsymmetrical mass may be provided at one place or more or one part or more may be removed or the disk or washer or weight may be bent or indented.

An unsymmetrical weight or washer or two or more applied to a symmetrical or unsymmetrical disk may be used along with a made unsymmetrical or out of balance or provided with a washer or weight or, two or more made unsymmetrical or out of bal: time as aforesaid and made to revolve by the yarn forming in themselves part of this-in.- vention provision is made {9r some movement of part of the disk athwart its axis symmetrical weight orwasher or two -or ;more and a symmetrical weight or washer ;or two or more may be applied to an unsymmetrical disk.

In specially advantageous forms of disk either transversely to that axis or into positions oblique to one another so that the disk may revolve eccentri'cally or wabble or swing in revolving. The provision for this movement of the disk may be made for example by the hole in the disk or the hole to receive the spindle of the disk being larger than the part to be received in it or by the hole being taper while the part to be received in it is cylindrical or vice-versa or by the hole and the part to be received in it being of different tapers.

Ordinarily if a disk having a bearing in its upper part is to be allowed to move laterally or to wabble. or swing in revolution provisionor clearance to allow lateral movement is made in its lower part so that the position of its higher part does not much change.

If provision be made for a disk to move in the direction of its axis of revolution this provision may be accompanied by greater opportunity for the disk to be moved transversely or to become oblique to the part on or in which it is mounted so that in moving in one direction along that axis in use it may revolve more and more eccentrically. This may be effected byproviding a conical or other'taper pin or projection to receive a disk or providing a disk with a conical or other taper pin or spindle.

Fig. 3 il ustrates an apparatus wherein the disk a is unsymmetrical, being made eccentric relatively to the pivot I), while the disk j is symmetrical and provided with an orifice C larger in diameter than the pivot b, so as to be movable laterally relatively to the pivot b.

Fig. t illustrates an apparatus wherein the disk j is unsymmetrical and the disk a is symmetrical.

The disk a is shown provided with weights or washers 0.

In Fig. 5 two disks a 7' generally similar to the disks a 7' shown in Figs. 1 and 2 are illustrated as provided with two unsymmetrical weights or washers 0 applied in the disk at around the sleeve Z thereof.

Fig. 6 illustrates a disk a made unsymmetrical by being indented at one side. Weights of a shape enabling them to be placed in the indented disk a maybe employed if desirable to increase the pressure upon yarn passed beneath the disk at.

In Fig. 7 hereinafter further described a disk a made unsymmetrical by the wall being thicker at one side 9 of the disk (2 than at the other is illustrated as applied to a disk which is symmetrical. In Fig. 8 also hereinafter further described a disk j made unsymmetrical by the wall being thicker at one side 7' of the disk than at the other is illustrated having applied to it a symmetrical disk a.

In Figs. 5 and 7 the disk a is shown as formed with a hole H a little larger than the sleeve ;0 of the disk j so that the disk It may be moved laterally relatively to the disk j in being turned upon it.

In Fig. 7. the pivot is shown as thicker at the top and tapers downward while the hole to receive it in the sleeve 12 is cylindrical.

In Fig. 8 the pivot k is shown as cylindrical while the hole to receive it in the sleeve 32 tapers from its mouth or entrance to the top.

In Figs. 7,and 8 it will be seen that the disks j having bearings in their upper parts the provision of clearance to allow lateral movement is made in the lower parts so that the position of the higher parts does not much change.

Fig. 8 also shows a symmetrical Weight 0 in the disk a.

Figs. 11 and 12 illustrate a disk j generally similar to that shown in Fig. 8 but formed with three holes t for the escape of dirt or other matter separated from yarn. The holes t are separated by radial spokes formed with rightangled edges which-may scrape yarn brought against them.

Figs. 13 and 14 illustrate a disk y' gen erally similar to that shown in Fig. 7 but formed with a hollow it around the sleeve 1) so that yarn pressed against it shall bear against the circumferential parts 12 rather than against the central parts thereof, and with four holes t for the escape of dirt or other matter separated from yarn. The holes t are separated by spokes which being below.

the hollow u do 'not receive contact of yarn passed between the disk y' and the disk a used with it.

If desirable in any case to facilitate revolution by reducing the surface of contact a .disk of a tension or yarn cleaning device formed or contrived in any of the ways hereinbefore described or in any combination of such ways may be provided with a rib or projection or ribs or projections or recess or recessesin the part to be in contact the other disk as the case may be or the yarn to be subjected to tension or cleaned. The disk used in any case may be beveled or rounded at the edges to facilitate the passage of yarn beneath or between it and another, each of the disks shown in the accompanying drawings being provided with rounded edges.

Figs. 15 and 16 illustrate a disk a generally similar to that shown in Fig. 7 but furnished on its lower face with ribs or projections y, six being shown in Fig. 15 but for the sake of clearness only two in Fig. 16.

By way of example of the provision of recesses Figs. 17 and 18 illustrate a disk a generally similar to that shown in Fig. 7

' with the surface on which it is-to rest or but furnished in its lower face with recesses 2, six being shown-in Fig. 17 but forthe sake of clearness only two in Fig. 18.

An apparatus provided according to this invention may be provided with or employed along with any guide or guides requisite or convenient for guiding yarn to or from it. Dlsks made or contrived according to this invention may be made of an suitable metal I or alloy of or glass or 'porce ain.

In any cases in which a washer or weight or two or more is or are to be applied to a disk with a central hole, the inner circumference of the disk is preferably provided. with a rim or flange as in the cases illustrated in Figs. 5, 6 but in other cases in which a disk is provided With a central 'hole the inner circumference of the disk may be provided or not provided with a rim or flange as may be considered desirable.

It is to be understood from the preceding description of the difierent disks provided according to this invention that difi'erent upper disks may be used with difi'erent lower disks as may be desirable in the building up of tension applying or yarn cleaning apparatus or from time to time as may be desirable and that the provision for the application of a weight or washer is only essential in cases in which such provision or such weight or washer is mentioned in the claims following.

Disks which are made unsymmetrical or out of balance as hereinbefore described, especially if made capable of lateral movement or swinging or assuming positions oblique to one another, become checked in their revolution at a lower speed than disks which are symmetrical or balanced.
