My invention relates to an arrangement for mounting the traveller ring of ring spinning and ring doubling frames in ring rails, made of sheet steel and the like.

In order to keep the moving masses in ring spinning and ring doubling frames as low as possible and also to save material, the ring rails frequently are made of sheet steel or light metal sheet which, however, is not thick enough to permit of using the conventional rings secured in the spindle support by means of an ordinary set screw.

It has been proposed to fix rings in novel rails of the kind mentioned, by employin a screw having a head that is conically shaped at its lower face for widening a split auxiliary ring, which in its turn is engaged in a recess of the traveller ring, and which anchors the latter in the ring rail. However, arranging the thread directly on the ring rails is disadvantageous since in case of damage the entire rail becomes useless or requires extensive repairs. Furthermore, the surface of the ring rail should be as smooth as possible, so that a screw head with washer is out of place there, and the ring is not securely held, since it may be tilted out owing to the play in the bore.

It has further been suggested to use screws, straps and the like which are arranged between the rings and bear on the ring flange for holding down the rings. This suggestion is open to the objection that either two such means are needed for each ring, which is uneconomical, or that the rings are coupled. If one of the means is loosened, it not only affects the directly pressed rings, but also the adjacent ones due to the movement of the rings in the bore and their sliding away from under the holding means.

My invention avoids these defects by providing the traveller rings of ring spinning and ring doubling frames, which rings bear with a flange on the ring rail, with a downwardly diverging conically formed exterior circumference below the said flange, which circumference is pressed onesided against the ring rail bore, and the latter likewise may be conically reamed on its under face. For engaging the rings onesided, the ring rail preferably is provided with conical bores for the reception of conically shaped nuts which with one side bear against their conical bore and with the other side against the ring-flange. The ring flanges suitably are recessed in conformity with the shape of the nut.

Such arrangement insures a simple manner of securing the traveller ring in the bore, in that the conical nut displaces the ring towards one side of the bore so that the ring is held there owing to its conical lower portion. The surface of the ring lath remains substantially smooth so as to prevent the adhesion of fibers. The conical nut with screw can be economically produced by mass production methods, and the bores for the nuts in the ring rail can be easily made. A particularly important feature of this method of fixing the ring is that it cannot be tilted out.

The invention is illustrated, by way of example, in the accompanying drawing, in which Fig. 1 is a vertical section of the ring fastening, and

Fig. 2 a plan thereof.

The ring 2, supported by flange 3, is mounted in the ring rail I. The outer circumference of the lower ring portion 4 is beveled, i. e. widened in a downward direction. A conical nut 5, held down by a screw 6 introduced from below, is mounted in a conical recess in rail I, the conical nut fitting in said recess. One side of the nut 5 is held in engagement with the bore wall of rail I, while its other side engages flange 3 of ring 2, which flange at this point preferably is provided with a recess 1 shaped to flt nut 5.

When screw 6 is tightened, nut 5 displaces ring 2 in the bore of rail I, until the beveled ring portion 4 is diametrically opposite to nut 5 in the bore of rail I. By means of screw 5 and the beveled outer circumference of the lower portion 4, ring 2 thus is anchored to the lower edge of the bore. Since the lower portion of the bore moreover is conically countersunk, the two faces will abut against each other so that ring 2, owing also to the inclination of the abutting faces, will be drawn into the bore and cannot emerge therefrom. Furthermore, all the rings are arranged absolutely uniformly and one-sidedly in rail I, thus facilitating the adjustment of the spindles.

What I claim and desire to secure by Letters Patent is:

1. An arrangement for fastening traveler rings to a ring rail in ring spinning and ring twisting machines, said rings being provided with an outer flange for hearing against an outer face of the ring rail and also being provided with an extending neck, said rail having a bore into which said neck extends, said neck having a conical outer surface enlarging away from the flange, said conically shaped surface of the neck extending the entire extent of the wall of the opening in the ring rail, a pressure applying means acting transversely of the neck for forcing the conical of the ring neck against the wall of the rail opening to wedge the ring between said conical surface and the ring flange.

2. A fastening arrangement according to claim 1, and in which the rail opening is conical at its portion remote from the surface. engaged by the flange and corresponds in shapemndf tapentothe neck of the' ring.

3. A mounting arrangement as defined in claim 1, and in which said rail is provided with a conical and the pressure applying means comprises a screw and a conically shaped nut for engaging the surface of the conical recess in the periphery of the recess in said ring for clamping the ring 5 firmly onto the ring rail.
