When a spool is pushed onto the hub and the hub is twisted relative to the spool, the triangular ones will tip Tension members around one of their two longitudinal edges lying in the longitudinal groove of the hub and thereby press theirs out of the Hub protruding long edge forcefully against the bobbin, so that it must join the rotation of the hub.

Even if this training has proven to be extremely effective, so that such couplings in large numbers are already in use in the relevant industry, it was found under the most varied of operating conditions naturally some points in need of improvement, so that the innovation is based on the task mentioned: Device to sell in this regard.

An innovation according to the chuck for bobbins and the like. Is therefore characterized in that it consists of a cylindrical body with at least one longitudinal groove running parallel to its longitudinal axis with a generally flat base and at right angles to this essentially parallel side walls in its outer wall and in this groove a tooth-like tendon with a substantially right-angled triangular cross-section is inserted in such a way that its one long side parallel to the flat base of the groove, its second perpendicular to the first longitudinal side parallel to the side walls of the N ₁ Ut, its third longitudinal side forming the hypotenuse of the cross-sectional triangle diagonally in of the groove and its outer longitudinal edge protrudes beyond the circumference of the cylindrical body, and that in the base of the groove on one side a longitudinal groove ^v for receiving the longitudinal edge between the lower and the sloping side surface of the S. Tension member is formed when it is rotated around this longitudinal edge.

In order to ensure a secure engagement of the protruding tendon edges with a pushed-on bobbin, the tendon is arranged between the base of the groove and the underside of the tendon, the tendon slightly lifting off the base. These elastic organs, which on the underside of the clamping member: can be fixed 'r r> .ahe whose end faces formed transverse grooves ^s, express their tensioning member well to the outside, but can be pressed together so much that the tendons at deferred bobbin on the base of its housing rest on the groove.

According to a special feature of the innovation, the base of the grooves for the tendons are slightly inclined to the longitudinal axis of the chuck, so that one end of the tendons protrudes a little further from the chuck body than with the other end. This is particularly advantageous when clamping very narrow bobbins, since the one-sided further protruding tendons are able to press such a bobbin against a stop collar of the chuck and thus any further backup becomes unnecessary.

Furthermore, the innovation proposes a special design of a retaining ring for the tendons, which from consists of two wire arches, each of which is bent over in a hook shape at one end and overlap each other, this being the case Overlap piece is surrounded by a coil spring pressing against the hook. To close this two-part Retaining or locking ring is at the free end of one arch wire through an eyelet at the free end of the other Arch wire can be passed through and on its own wire

hinged. In addition to its ability, the tendons inserted into the longitudinal grooves of the chuck body in these Holding grooves in place is made easier by a locking ring of this type in connection with another special feature of the Another innovation, however, is the sliding of a bobbin onto the chuck. There is a block of rubber or another elastic material between the underside of each tendon and the base of its The receiving groove is inserted eccentrically in such a way that the end of the tendons facing away from the push-on end of the chuck something is raised. The compression spring of the locking ring now pulls the other ends of the tendons into the Grooves in it so that a bobbin can be pushed on easily. The rubber blocks are pressed together, until the external pressure is so strong that the tendons tilt like a seesaw on the rubber block and are in full Grip the length on the bobbin ..

Longitudinal edge 32 of the tendon is usually slightly above protrudes the circumference of the cylindrical body 10. These Tension members 27 are located when the chuck is not in use, i.e. no coil is slid on, in which in Figure 5 shown position, with the underside 29 of each tendon on the raised surface 22 of the base a longitudinal groove rests or something lifted from this is as will be described below. The ends 33 of the protruding parts of the tendons 27 are preferably beveled to below the surface of the chuck body, as shown in FIG. The locking ring 26 engages in a central transverse slot 34 of each tension member and is below the External surface of the chuck body.

As FIG. 4 shows, the underside 29 of each tendon 27 preferably rests on short cylindrical organs made of rubber or a corresponding elastic material, which are glued or otherwise fastened in semi-cylindrical ruffled transverse grooves 36 near the ends of the underside 29, these elastic organs or rollers rest in the recessed widenings 21 of the longitudinal grooves, as shown in FIG. The diameter of these elastic organs 35 is so large that the undersides of the tendons are normally somewhat above the raised base area 22 of the longitudinal groove. On the other hand, however, these organs are so elastic that they can be pressed together when a bobbin is placed on the chuck . is pushed. In other words, the outer longitudinal f aknt 32 of each tension member is pressed elastically from the inside against a coil body B when it surrounds the chuck A.

When the attached bobbin B is rotated in the direction of arrow 37 (Fig. 6) with respect to the chuck 10, Each tension member 27 tends to tilt about its longitudinal edge 39 between its side surfaces 29 and 32. Included This longitudinal edge 39 slides into the groove 23 between the raised base 22 and the side wall 20 of the longitudinal groove, this longitudinal groove 23 this longitudinal edge 39 of the clamping member holds in the longitudinal groove of the putter body 10. Since the side surface 31 of each tendon is wider than the other two sides 29 and 30, the longitudinal edge 32 of each tendon digs itself during this pivoting movement into the pushed-on bobbin B, as shown in FIG.

Figure 7 shows a somewhat modified training which is particularly suitable to be able to clamp narrow bobbins on the chuck without special arrangements must be provided to prevent axial movement of such narrow coils on the chuck. Of the Chuck body 40 has a stop shoulder 4l, against which the end of the spool to be clamped is pushed will. The chuck has a series of evenly spaced longitudinal grooves 42 from which one is shown in FIG. A second row of similarly distributed longitudinal grooves 43 can follow this first row of grooves 42 are provided. The difference between the longitudinal grooves 43, 42 and the above Longitudinal grooves 17 consists in that the bases of the longitudinal grooves 42 and 43 are not parallel to the chuck axis run, but somewhat inclined to it, so that the ends 44 of the longitudinal grooves closest to the stop shoulder 41 are slightly deeper than the outer ends 45. Incidentally, are

however, the longitudinal grooves are designed in the same way as the longitudinal grooves 17 described above.

In this training, the tendons 27 have the inclination to press a pushed-on bobbin in the axial direction along the chuck against the stop shoulder 4l, since the ends of the tensioning members 27 on the right in FIG. 7 press deeper into the coil body than those which are closer to the shoulder 41 left ends, so that the bobbin is literally pressed against the shoulder 4l. For the sake of clarification it should be noted that in Figure 7, the inclination of these tendons is shown somewhat excessive to the Explain principle.

Another embodiment which has proven to be particularly favorable under certain operating conditions is shown in FIG. The tension members 27 can be formed here in the same way as already described and the Longitudinal grooves 46 in the chuck body 50 are expedient also designed in the same way as already described in connection with the longitudinal grooves 17 became. The training shown in this figure is particularly suitable for newsprint spindles in which a A chuck pushed into the hollow paper rolls by a cam drive clamps them tight. In the case of the Training is a block 47 made of rubber or another compressible elastic material on the base of the longitudinal grooves 46 between the center of the underside of the clamping member 27 and its end 49, which is the receiving end the spindle 50 for the paper roll B is closest, arranged. The spindle 50 is BEZW in the coil. the Paper roll B pushed in in the direction of arrow 51.

At this time, the elastic block 47 is pushed by the paper roll B. compressed and the tendon 27 can pivot to a certain extent between its ends around this block, whereby this happens something like a seesaw.

The retaining ring used to hold the tendons in their receiving grooves is shown in detail in FIGS.

When the other wire ends are pulled, the spiral spring 56 arranged between the hook ends 53 and 55 is naturally compressed.

The free end of a spring wire 52 is for training an elongated eyelet 57 bent back and by means of a hook-shaped end 59 hooked to the rest of the spring wire 52. The free end of the other spring wire 54 is formed into a short eyelet 60, through which an eyelet 61 of a short wire bracket 62 passes. This wire hanger 62 has a hook 63 at the free end, which over the Eyelet 57 of the other spring wire engages. In this in Figure 10 position shown, the retaining ring can be pushed over the chuck until it is correctly in the Circumferential groove of the chuck body and the grooves 54 on the Outer edge of the tendons 27 lies. As soon as this position is reached, the wire bracket 62 is in the direction of the arrow 64 (Fig. 10) pivoted up, so that the end 60 of the spring wire 54 and the eyelet 57 of the spring wire 52 ate drawn together will.
