Flexible joint for conduit

A flexible and selectively adjustable joint for conduit comprising;

• joining and conduit members having telescoped end portions and longitudinal axes, cooperating sliding sealing means between said end portions sealing said end portions during angular movements of said members relative to one another, opposite pivotal connecting means pivotally connecting said end portions together on a pivot axis which intersects said longitudinal axes, selective adjustment means on said pivotal connecting means for selectively moving said members relative to one another generally parallel to said longitudinal axes and varying the engaging force between said cooperating sealing means, said pivotal connecting means including aligned sockets on said end portions and pins rotatably received in said sockets, said selective adjustment means including cam means on said pins cooperating with said sockets on one of said end portions for moving said members relative to one another generally parallel to said longitudinal axes upon rotation of said pins relative to said sockets on said one end portion, and releasable locking means releasably locking said pins against rotation relative to said one end portion while maintaining relative rotation between said pins and the other of said end portions.

A flexible joint for conduits comprising;

• a joining member having a longitudinal axis and being formed from two parts which are sealingly connected together in a plane extending generally perpendicular to said axis, generally spherical surface portions on each of said parts on opposite sides of said plane and facing toward said axis, said spherical surface portions curving outwardly away from said axis from locations adjacent said plane and having sphere centers intersecting said axis, a pair of conduits having end portions received in said parts, pivotal connecting means pivotally connecting said conduit end portions to said parts on pivot axes intersecting said sphere centers and lying in planes extending generally perpendicular to said axis, said pivot axes extending generally perpendicular to one another, circumferential sealing means on each of said end portions of said conduits engaging said spherical surface portions, and yieldable biasing means carried by said end portions biasing said sealing means on each said end portion toward said plane in which said two parts are connected together and into firm sealing engagement with said spherical surface portions.

A flexible joint for conduits comprising;

• a generally cylindrical joining member having a longitudinal axis and opposite joining end portions, a pair of conduits having conduit end portions received in said joining end portions, said conduit end portions having outer spherical surface portions lying on the periphery of spheres having sphere centers intersecting said axis, pivotal connecting means connecting said conduit end portions to said joining member on pivot axes intersecting said sphere centers and lying in planes extending perpendicular to said axis, said axes extending perpendicular to one another, generally cylindrical sheet metal members secured to said joining member interiorly thereof and having cantilevered terminal portions extending inwardly toward said axis and providing yielding deformation of said cantilevered terminal portions and sealing means sealingly engaging between said cantilevered terminal portions and said spherical surface portions.
