804,364. Rotary engines. McCLOSKEY, J. March 1, 1956 [Dec. 13, 1954], No. 35956/54. Class 110 (2). [Also in Group XXIX] Liquid under an hydrostatic head passes from one end of a pipe 2, via a passage 16 in a block 6 on the pipe 2 and a radial pipe 9, to the upper one 11 of two tanks rotatable with a tube 7 around the block and, as the tank 11 fills, the displaced air, passing via a pipe 13 into the previously filled lower tank 12, forces the liquid therefrom via pipe 10 and passage 17 and out of the other end of the pipe 2, so that the now heavier tank 11 descends, rotating the whole tank assembly about the pipe 2. The displaced liquid is ejected through spraying apertures 5 and the apparatus, mounted on wheels 3, 4, progresses along an elongate closed circuit rail 1 by virtue of the wheel 4 being fixed to the tube 7. To ensure unidirectional rotation, the apparatus is so arranged that the angle between the axis of the upper tank and the horizontal (measured in the desired direction of rotation) is less than 90 degrees. For this purpose, each tank may have a projecting rod 24 which depresses a spring-loaded catch 25, to pass it in the desired direction and to come to rest against it as the tank swings back. The catch may carry a magnet 27. Three tanks spaced at 120 degrees may replace the two diametrically opposed tanks, the individual air pipes being interconnected at a central point. The apparatus is so balanced that, when turning around each end of the circuit, it can travel on its driving wheel only. Additional air, to maintain the supply, may be introduced to the system by a pump operated by the reverse swing of the tanks in coming to rest, or may be entrained by running the supply outside the hydraulic gradient. It may be used for irrigation, the supply of nutrient solution, or to dirve any other device. The pipe 2 may be arranged to rotate about a fixed vertical axis, the wheel 4 running on the ground. |
