Pipe coupling
First Claim
Patent Images
1. A pipe coupling, comprising:
- a cylindrical barrel sleeve having a circumferential flange at each end;
a clamping ring mounted to each circumferential flange, at least one of the clamping rings carrying a seal, the clamping ring having two separate portions connected together at a pivot point so that each clamping ring portion is movable toward and away from the other one, and wherein the clamping ring portions are characterized in that the clamping ring portions become iron-bound at a certain rotational point as the clamping ring portions move toward each other, in a manner so as to cause the clamping ring portions to function as a unitary ring.

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.

9. A clamping ring for a pipe coupling, comprising:
a clamping ring that is characterized in that the ring closes around the circumferential flange as the ring is tightened, the clamping ring having separate portions connected together so that one portion may swing relative to the other, and wherein the clamping ring portions are characterized in that the clamping ring portions become iron-bound at a certain inward swing point so as to cause the separate portions to function as a unitary structural member that will bend inwardly as the clamping ring closes.

10. A cylindrical barrel sleeve for a pipe coupling designed to couple together the ends of two pipes having an internal diameter within and including the range of four to twelve inches, the barrel sleeve having a handle for manipulating the sleeve while coupling the ends of the pipes.
