ABSTRACT:
A mechanical pipe joint comprising a substantially cylindrical body integrally formed with a plurality of pipe restraining members, and a plurality of pipe clamping members, each comprising at least one block slidably engaged with a pipe restraining member, a compressible gasket for graduating suddenly applied forces, and restraining bolts. The clamping system, acting to distribute the clamping forces on a large portion of the surface area of a pipe, simultaneously absorbs and graduates suddenly applied forces, preventing failure of the pipe point.
