To all whom it may concern Be it known that I, JOHANN .FRANZ.'-ROTH a citizen of-the; Swiss Republic, and resident of Basel, Switzerland, have invented new and useful Improvements in Thread-Wind ing Apparatus for Ring-Spinning and Ring-Doubling Machines, of which the following is a full clear, and exact specifica tion.

In thread winding apparatus for ring spinning and ring. doubling machines in which the ringsrotate with the spindle, it is known to brake the threadgui'des or winders which tendto rotate with the rotating rings, by friction on the ring in order to make correct winding possible. While the braking devices hithertoproposed for this purposeare either not adjustable at all or only with difficulty, during the operation of the apparatus, in the thread winding ap-" paratus according to this invention, the thread'guide on the rotating ring is braked according to the delivery of thread and the desired winding tension for the thread is capable of being varied during'the operation by means of a non-rotatable brake ring arranged adjacent to the rotating ring.

This brake ring embraces the rotating ring and is adjustable relatively to the rotating ring in the vertical direction. It is funnelshaped inside and its inner conical wall will allow a braking effect during'the rotation of the thread guide bearing upon it to a greater orv less extent. depending on the ver- Y tical position of adjustment imparted to the brake ring and in certaincases also allows a simultaneous ad ustment of the friction of the guide on the rotating ring. ,The brake ring surroundingthe rotating ring and the thread'guide serves at the same time as a protector for the thread guide and the annular race therefor on "the ring.

An example of construction according to the invention is illustrated in the drawing: Figure 1 is the end view of the spindle beam of a ring spinning machine to which theinventionis applied. Fig. 2 is a partial plan of the same. Fig. 3 is a view-at a right angle to Fig. 1 the brake ring being lowered.

Fig. 4 shows the brake ring to-an enlarged scale in conjunction with'the thread guide or winder.

The thread d (Figs. 1-3) coming from the delivery rollers is passed onto the rotating spindle a shown broken away "below, by

-*' mg ring 9' and is wound to a cop in the ollow cylindrical ring carrier 6 which is ggshown broken away below and rotates with the. spindle a, by reason of the alternate rising and falling of the spindlea in known manner. 7 1 Y Each rotating ring 9 is furnished with a brake ring '7) embracing it. The brake ring I) is funnel-shaped inside and is not rotatable. The same is placed on two rods 2' and is fixed on these rods by means of the screws 70. The rods 2' are hinged atvn on the T-shaped supportm and are clamped tightly against the projection 0 on the support m when they are inthe position shown in full linesin Fig. 1 in consequence oftheir own springmess.

The brake, ring 1) can be turned downward on the support m into the position shown in'chain lines in-Fig. 1, by means of a projecting finger 2, provided on the brake ring; in this position the thread'guiolec is released from the brake ring I) so that this latter allows of the easy introduction of the thread into the guide 0.

The support 'm/is adjustable in vertical slots on a .supporting rail f and secured.

' thereto by screws a, which rail is vertically adjustable by means of a linksystem Q connecting it with a control rod 1- displaceable horizontally in bearings 0. In this way, the brakering b can be vertically adjusted relatively'tothe ring 9 in order to cause its conical inner wall to press to a greater or less extent against the guide 0. The rod 1' may bedisplaced by means of a lever Z pivoted at t-to the spindle beam h. 1

face of the'brake ring 6 upon which owing to its centrifugal force it will exert a pres sure; owing to the friction thereby set upbetween the thread guide 0 and the inner wall of the *brake ring I the thread guide 0 is braked'upon the ring 9, which tends to.

carry it along with it,'so that the thread is wound on the bare spindle ornupon a cop;

by, in certain cases, the friction of theguide on the rotating ring 9 may simultaneously ringg hasa tendency, to carry the guide 0 resting on it, along with it. In order, therefore, to brake the guide 0 immediately the winding begins which is, of course, essential in order to prevent the thread d de-, livered by the delivery rollers from forming loops or knots, easily receding projections are arranged on the lower part of the brake ring I), which, when the spindle begins to rotate, are designed to eflect a positive braking action on the guide. These projections consist, as'best shown in Fig. 4, of freely movable balls a: of metal, leather, cork and so forth. They are mounted in passages in ,the brake ring 6 inclined downward and closed at' their outer end by studs 8. At their inner end, however, they are open. This arrangement isof such a kind that the ,ballsae cannot fall into the interior of the brake ring, but are always projecting suii'iciently over the inner wall of the brake ring toform very resilient projections for the thread guide striking against them.

Upon starting the spindle, thebrake ring .b is lifted by means of the lever Z tosuch an extent that the projecting balls w lie at the same level as the thread guide 0 in order to effect a positive braking action upon it (Fig. 4). Immediately the ring g has attained an average speed, for example, 1,000 revolutions per minute, the brake ring I;

can be brought into the desired adjusting position, for example, can be allowed to settle into the braking position shown in Fig. 1, in which the thread guide 0 is braked owing to its bearing on the inner wall of the braking ring 6.
