Abstract
The invention provides a siphonic apparatus to effect irrigation of a field from a water supply. The apparatus comprises a bridging structure which includes a chassis fabricated from spaced longitudinal bottom members, spaced longitudinal top members interconnected by cross members, vertical struts, diagonal braces and side plates to form a rigid structure having a central elevated section and downwardly angled end sections, the ends of which being on substantially the same plane as the surface supporting the chassis. At least one siphonic tube is rotatably, transversely supported in the chassis. The tube has an inlet portion and an outlet portion which extend from either side of the chassis, the tube being rotatable in the chassis from a position where the inlet and outlet portions are clear of the surface supporting said chassis for transportation purposes to a position where said inlet and outlet portions are in a plane normal to the horizontal axis of said tube, said tube having a suction valve located adjacent its inlet and a valve to selectively open and close said outlet. In its preferred form the spaced top members have decking fixed therebetween and constituting wheel trac…
