Abstract
Abstract An improved liquid aeration device which comprises a power driven, floating cylindrical rotor structure with an inclined baffle located in the downstream portion of the rotor, the rotor being immersed and rotated through the liquid being aerated, thereby causing particles of the liquid to be impinged upon the baffle so as to cause substantial turbulence and the transfer of large quantities of air into the liquid.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
184 words
A floating self-propelled water aerating unit on a body of water and tethered about a fixed pivot point on said body of water, said unit comprising, in combination: a frame including float means capable of supporting said frame on the surface of said body of water; a power driven rotor rotatably mounted on said frame and adapted to be rotated about a horizontal axis into said body of water so as to force particles of water out of and away from said body of water and to propel said aerating unit over the surface of said body of water; a flat baffle plate mounted on said frame rearward of said rotor at an angle of approximately 45* with the surface of said body of water and extending from substantially above to beneath the surface of said body of water to intercept the particles of water forced out of said body of water by said rotor; and means connecting said frame to said fixed pivot point on said body of water for tethering said unit about said fixed pivot point on said body of water.
