  • Pipe coupling with teethed inserts, method of securing teethed inserts, and method of coupling piping
    Patent number: 9285060
    Abstract: A coupling for joining plan end pipe having a housing made from a casting with a pocket disposed in the casting. The pockets holds an insert that engages the plain end pipe, and the insert is secured to the housing without the use of machined features on the housing or the use of additional components or adhesives to secure the insert to the housing. In a preferred embodiment, each insert is disposed in a pocket on the inner surface of the coupling assembly, with projections extending from the inner surface disposed within cavities on opposing sides of each insert to retain the insert within the pocket by obstructing the opening to the pocket. A preferred device and method of forming the projections is a press that deforms the projections to retain the inserts in the pockets.
