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.
An apparatus for connecting two pipes together, comprising: (a) a spherical ball having an axial passage therethrough and adapted to be joined in fluid communication with a first pipe; (b) a receptacle means having an axial passage therethrough and formed of a female cavity having a surface matching
An apparatus for connecting two pipes together, comprising: (a) a spherical ball having an axial passage therethrough and adapted to be joined in fluid communication with a first pipe; (b) a receptacle means having an axial passage therethrough and formed of a female cavity having a surface matching that of said ball which surface is less than a hemisphere and which encircles said ball by at least 180 degrees, said receptacle means adapted to be joined in fluid communication with a second pipe; (c) clamping means for holding said ball in said receptacle means and aligning the axial passages thereof to enable fluid communication between the first and second pipes; (d) said clamping means securing said ball in said receptacle means by clamping said ball on its outer surface at a location on said ball on the exposed side opposite the hemisphere in said receptacle means and wherein said clamping means includes: (1) a circular first ring around said ball having a diameter enabling it to contact said ball without passing over said ball; (2) an external protruding lip on said receptacle means; and (3) means for locking said ring to said lip wherein said locking means comprises (4) an encircling second ring having a pair of spaced, internally directed shoulders which are spaced to encircle and abut said first ring and said lip in a side-by-side relationship.
