ABSTRACT:
Sprinkler irrigation apparatus of the general type comprising a central-pillar assembly at the center-pivot site of the land tract to be irrigated, a generally horizontal lengthy water distributing conduit having spaced flexible couplings and nozzles and also traction supports at the terrain. The improved central-pillar assemblies herein disclosed, when utilized for electrically driven and controlled irrigation apparatus, have provision for the electrical commutation means to be located in elevation below the outlet-elbow means feeding the inward-end of the water distributing conduit. Electrical surveillance of the apparatus tract performance might also be initiated from nearby the low-elevation commutation means. The improved central-pillar assemblies might also be equipped with more efficient and utilitarian medial-piping feeding water to the conduit inward-end, the medial-piping arrangement being inherently sturdy whereby the need for external bracing is minimized. The central-pillar assemblies disclosed have provision for a primary-balljoint that minimizes stress to the elongate water distributing conduit as it traverses rough and uneven terrain.
