Abstract: A mounting arrangement includes a first bracket, a second bracket including a slot, and a series of washers, with two resilient washers. First and second bolts extend through the first bracket, a first and second of the washers, the slot of the second bracket, a third and fourth of the washers, the resilient washers, and a fifth and sixth of the washers. The second bracket frictionally engages the first and second washers, and frictionally engages the third and fourth washers.

Abstract: An underwinding thread clamp for a spindle of a ring spinning or ring-twisting machine has a clamping sleeve biased by a spring against and juxtaposed with a collar on the spindle. The juxtaposed surfaces of the spindle and collar have wavy contours so that, upon engagement of an actuating member with each collar, the latter is cammed into its open position to release the respective underwinding thread so that the latter, engaged when a full bobbin was removed, can be released. The clamping of the underwinding thread permits the thread to be wound on the newly mounted core sleeve.

Abstract: A spindle for gas bearing of a rapidly rotating tool, in particular for aerostatic bearing arrangement of an open-end spinning rotor, including a spindle housing, a rotatable elongate shaft supported in the spindle housing in a radial direction of the shaft by a radial gas bearing element and an elongate extension rod. The rotor is coupled to the extension rod at a first end thereof. An extension rod bearing element is arranged at a region proximate the first end of the extension rod at which the rotor is attached. A first bearing clearance is defined between the radial bearing element and the shaft and a second bearing clearance is defined between the extension rod and the extension rod bearing element which is at least twice the first bearing clearance.

Abstract: A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.

Abstract: A textile spindle mount is provided by the subject invention in which a layer of elastomeric material is disposed between and attaches to a flat washer along its bottom surface and a cupped washer along its top surface. The cupped washer includes end sections which extend downwardly and attach to the outer edge of the elastomer layer for limiting the bulging thereof under compression loads. The bulging of the elastomer layer is further controlled by removing a generally curved section of elastomeric material adjacent the outer edge of the elastomer layer. As a result, a high compression to shear springrate ratio is obtained with the spindle mount herein which is capable of good noise and vibration isolation and can accommodate high compression loads without bond failure.

Abstract: An adjustable support system mounts one member, such as a textile spindle, on a second member, such as a textile machine rail, so as to reduce the transmission of vibrations between the two members. The support system incorporates a flange to which is secured an elastomeric element for resiliently mounting the textile spindle relative to the flange. The flange is kept spaced apart from the machine rail by a member or members that at least contact the flange and at least contact the machine rail. The spacing between the flange and the machine rail can be adjusted through manipulation of adjusting screws or bolts in such a manner as to change the orientation of the flange and the textile spindle mounted on the flange relative to the machine rail. Like the spacing member, the adjusting elements contact both the flange and the machine rail.

Abstract: A noise reducing washer for the spindle of a textile machine has a pair of outer hard resilient washers, for example, of nylon, and a soft washer, for example of rubber, sandwiched therebetween.

Abstract: A noise and vibration attenuating support mounts a rotating member that tends to tilt about and translate along axes transverse to its axis of rotation. The support incorporates a body having mass and a moment of inertia with respect to an axis through the center of gravity of the body. Resilient elements, which are secured to the mass body, mount the rotating member resiliently relative to the mass body and the mass body resiliently relative to a second member. When mounting the rotating member, the support circumscribes and is coupled to the member such that the center of gravity of the rotating member is spaced along the axis of rotation from the center of gravity of the mass body. The support also predominately determines a translational natural mode of vibration with an associated natural frequency at which the mass body translates in resonance along axes transverse to the axis of rotation of the rotating member.

In the case of the spring urging the sleeve into the engaged position a toggle linkage is provided to hold the device in this position. In the arrangement where it urges the whorl away from the belt a spring-loaded device operated by a thread-tension sensor downstream of the apparatus is provided to stop the device in case of thread rupture. A brake is provided on the spindle shaft to arrest it when it is swung out of engagement with the belt.
