COMBINATION SEALING MEMBER AND PIPE COUPLINGS
First Claim
1. In combination, a sealing member and a coupling, said coupling comprising:
- a plurality of segments joined end to end, said coupling for securing pipe elements together in end to end relationship, said segments having arcuate surfaces facing inwardly and engageable with outer surfaces of said pipe elements, said segments having adjustably tightenable connection members for drawing said segments together, said sealing member being positioned between said segments and comprising;
a flexible, resilient ring having a ring inner surface adapted to engage said outer surfaces of said pipe elements, said ring inner surface having a diameter sized to receive said pipe elements upon insertion of said pipe elements between said segments, said ring having a ring outer surface having a diameter sized to support said segments in spaced apart relation sufficient to allow said pipe elements to be inserted therebetween; and
wherein upon tightening of said connection members said segments being movable toward one another compressing said ring, said ring being deformable upon motion of said segments to permit engagement of said arcuate surfaces with said pipe elements.

Abstract
A sealing member is disclosed having an outer surface that supports segments of a pipe coupling for joining pipe elements in end to end relation. The segments are supported in spaced relation to permit the pipe elements to be inserted into the coupling without disassembly. The sealing member is a flexible ring that has conical lips around its inner circumference to engage and guide the pipe elements into the coupling. A tongue extends radially inwardly between the lips, the tongue having conical shoulders which engage and guide the pipe ends. The tongue locates the coupling segments relatively to the pipe elements.

15. In combination, a sealing ring and a coupling, said coupling comprising:
a plurality of segments joined end to end, said coupling for securing pipe elements together in end to end relationship, said pipe elements having an outer surface of substantially cylindrical profile, said segments having arcuate surfaces facing inwardly and engageable with said pipe element outer surfaces, said segments having adjustably tightentable connection members for drawing said segments together, said sealing ring being positioned between said segments and comprising;
a radially facing backwall having a ring outer surface having a diameter sized to support said segments in spaced apart relation sufficient to allow said pipe elements to be inserted therebetween;
first and second sidewalls extending substantially radially inwardly from said backwall, said sidewalls being in spaced apart relation on opposite sides of said ring;
first and second lips attached respectively to said first and second sidewalls, said lips projecting inwardly toward one another, and each having a conical surface facing outwardly and adapted to engage and guide said pipe elements inserted between said segments;
a tongue attached to said backwall and extending circumferentially around said ring, said tongue being positioned between said first and said second lips and projecting substantially radially inwardly, said tongue being engageable with said pipe elements upon insertion thereof for positioning said segments relatively to said pipe elements; and
wherein upon tightening of said connection members said segments being movable toward one another compressing said ring, said ring being deformable upon motion of said segments to permit engagement of said arcuate surfaces with said pipe elements. - View Dependent Claims (16, 17, 18)
