ABSTRACT:
A wheel for elevating water from moving streams, for purposes of irrigation and the like, consisting of a wheel supported for rotation on a horizontal axis, being supported for example by a barge moored in the stream, with the lower portion thereof immersed in the stream and having paddles mounted about its periphery whereby it is turned by the momentum of the stream water. At least certain of the paddles carry buckets which elevate water from the stream and dump it in a trough at a higher elevation than the stream level, from which it may flow for irrigation or other uses. The buckets are so configurated, and are movable relative to the wheel in such a manner, as to both dump the water at a maximum elevation in the wheel elevation, and also to provide a turning torque at the descending side of the wheel, so as to assist in its operation.
