ABSTRACT:
An improved articulated ball connector for use with pipelines as disclosed. In the illustrated embodiment, a sphere is attached to the end of a pipeline. A collar is fitted about the sphere. The collar has a surface contoured to match the surface of the sphere and its rotates or deflects through a designated angle. The collar has an encircling outer groove. A cup shaped receptacle receives the curved surface of the ball. The collar is abutted against a transverse shoulder on the cup shaped receptacle. The ball is pivoted relative to the cup shaped receptacle and the collar. A ring having a cross section which is U-shaped latches about the cup shaped receptacle and the collar. The U-shaped cross section includes upper and lower shoulders which protrude inwardly and engage the cup shaped receptacle and the groove in the collar. The ring is squeezed radially inwardly to clamp the cup shaped receptacle and the collar together. The ring is held at the radially inwardly directed position by means of a tapered wedge which fully encircles it and jams it inwardly. The tapered wedge is in the form of a hydraulically moved ring within a cylindrical housing.
