ABSTRACT:
An articulating pipe coupling and alignment control assembly is described for center pivot sprinkler irrigation systems. The assembly interconnects adjacent pipe sections to enable the section to pivot both vertically and horizontally with respect to each other. The assembly includes two spaced pipe section flanges that are affixed to the ends of the pipe sections. Pipe segments are welded to the flanges with a coupling member fitting over ends of the pipe segments to enable water to flow therebetween. The assembly as an external ball and socket interconnection affixed to the pipe segments to enable the pipe sections to pivot about axes of the ball and socket interconnection. An articulating arm assembly is mounted above the ball and socket interconnection for operating a switch activating shaft to maintain the adjacent pipe section in general longitudinal alignment.
