  • Patent number: 11274777
    Abstract: A pipe coupling includes a sleeve and a clamping ring. The sleeve includes a flange at least one end. The clamping ring is mounted to the flange. The clamping ring carries a seal and includes two spaced apart bolt engagement portions. The clamping ring further includes two separate clamping ring portions that are removably connected together at a coupling portion of each respective separate clamping ring portion so that each clamping ring portion is separable from the other one. The two separate clamping ring portions function as a unitary ring when the coupling portions are brought into abutting contact such that the coupling portions are fixed relative to each other.
    Type: Grant

  • Patent number: 8448993
    Abstract: A pipe coupling for connecting pipes of the same or different diameters. The coupling has a barrel sleeve with clamping rings on each end. The clamping rings each carry nested seals. An inner portion of each nested seal may be removed so as to adapt the clamping ring to different pipe diameters. Each clamping ring is hinged, but becomes iron-bound upon tightening, so that each ring eventually bends as a unitary ring member.
