  • Patent number: 3974634
    Abstract: Resilient mounting means for a traveler cleaner fixed to a textile ring holder includes a resilient member, formed from a vibration damping material such as rubber, fixed into or integral with a textile ring holder formed either of such material itself, or of metal, or of a combination sandwich type construction in the region in which the cleaner is to be fixed to the ring, and having embedded within and bonded thereto a threaded sleeve or stud to receive the cleaner. This mounting means permits the traveler cleaner to be resiliently restored to its aligned position relative a spinning or twisting ring and its traveler following accidental impact.

  • Patent number: 3946545
    Abstract: Spindle units adjacent each side of a textile twisting machine are mounted, for noise abatement purposes, in vibration insulated relationship to the frame of the machine, to all spindle units adjacent the other side of the machine, and preferably also to other spindle units adjacent the same side of the machine. The spindle units are so mounted by a plurality of rigidly constructed but resiliently supported mounting assemblies. Each assembly includes an elongate spindle supporting member extending longitudinally of the twisting machine adjacent one or the other side thereof, and at least one transverse stabilizing member extending laterally inwardly therefrom toward, but terminating short of, the opposite side of the machine.
