Abstract
Abstract A disc is rotatably mounted in a position to be partially exposed to, or immersed in, a liquid. Slow rotation of the disc causes liquid adhering to the disc to move upward into a position where wipers remove most of the adhering film, and divert it into a drainage trough or collector. In the simplest form of the invention, the disc is of magnetic-responsive material, and the wipers are flexible strips having permanent magnetism.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
180 words
A machine for elevating liquid material, said machine including frame means and plate means rotatably mounted on said frame means, and also including wiping means and collector means adapted to remove liquid from said plate means, and drive means adapted to rotate said plate means, wherein the improvement comprises: at least two plates constituting said plate means mounted respectively on spaced axis of rotation and in overlapping relationship; bracket means interposed between said plate, and mounted on said frame, said bracket means having a receptacle slot, and said wiping means is a flexible strip normally received in said slot and engaging said overlapping plates along the opposite edges of said strip, said bracket means constituting the sole supporting and retaining means for said strip, said drive means being operative to induce a common direction of rotation of said plates; and wherein said slot is normally inclined to the horizontal, and has a serrated edge on the side thereof facing the direction of rotation of one of said plates, and said one plate is mounted below the other of said plates.
