<p>COUPLING ARRANGEMENT USABLE IN A TEXTILE MACHINE In a coupling arrangement for a textile machine, a drive shaft can be intermittently rotated and a connecting member encircles and is connected to the drive shaft by an eccentric hoop located between them. A coupling key is displaceable by a connecting member between a coupling recess associated with the drive shaft and a coupling recess associated with the connecting member. The coupling key is retained in the recesses by lead cams. A retaining key, independent from the coupling key, is supported by the eccentric hoop. The retaining key cooperates with a retaining recess on the drive shaft or with a retaining recess on the connecting member. The retaining key and/or the retaining recess have control surfaces which provide the displacement of the retaining key when the drive shaft overtakes the eccentric hoop or the eccentric hoop overtakes the connecting member.</p> |
