Abstract

A conveying device for conveying liquid from a supply well features an upright wall having one major surface and extending into the well, conveying means comprising a disk rotatably mounted about a substantially horizontal axis and a plurality of separations connected to the disk about the axis, the wall abutting the separations, a portion of the surface of the wall, the separations and the disk defining cells for conveying the liquid along at least part of the wall surface, and an output channel defined in the wall and intercommunicating with at least one of the cells when in a position near the top of the disk for emptying liquid from the cells as they reach the position; Whereby, when the disk is rotated, it will move the separations into the liquid and the cells will substantially retain their liquid contents until they reach the position.
