Abstract

Water is supplied from a preselected depth in a body of water by an intake held at the preselected depth by a stem connected to a float which rides near the surface of the water. The stem is weighted to maintain a desired orientation of the device in the body of water. A guide is provided in the body of water to maintain the horizontal position of the intake means.

Claims

1. Apparatus for supplying liquid from below the surface of a body of said liquid comprising intake means for receiving said liquid, float means for floating in said body at a predetermined relationship with respect to said surface and for supporting said intake means, stem means for connecting said float means to said intake means such that said intake means is below said surface, and outlet means for directing the flow of said liquid from said intake means, wherein said stem means is structured to be of substantial weight and density for ensuring that said intake means is maintained in said body of liquid at a predetermined depth below the surface of said liquid and in a predetermined orientation with respect to said float means for withdrawing liquid from said predetermined depth regardless of changes in the level of said liquid.

2. Apparatus according to claim 1 wherein said float means is designed to ride on the surface of said body of liquid.

3. Apparatus according to claim 1 wherein said float means is designed to ride on the surface of said body and said stem means is located to hold said intake means directly below said float means.

4. Apparatus according to claim 3 wherein said body of water is behind a dam, and said outlet means extends through said dam.

5. Apparatus according to claim 3 further comprising guide means for engaging said outlet means and maintaining the horizontal position of said intake while permitting free vertical movement of said intake means.

6. Apparatus according to claim 5 wherein said body of water is behind a dam, said outlet means extends through said dam, and said guide means is located between said float and said dam.

7. Apparatus according to claim 6 wherein said guide means comprises parallel bars on opposite sides of said outlet means.

8. Apparatus according to claim 1 wherein said stem means comprises a plastic pipe.

9. Apparatus according to claim 8 wherein said plastic pipe is filled with concrete.

10. Apparatus according to claim 8 wherein said plastic pie is solid.

11. A method for supplying water from a selected depth in a body of water comprising providing float means for floating in said body at a predetermined relationship with respect to the surface of said body, providing intake means for receiving said water, and supporting said intake means with stem means connecting said float means to said intake means, wherein said stem means is structured to be of substantial weight and density for ensuring that said intake means is maintained in said body of water at a predetermined depth below the surface of said water and in a predetermined orientation with respect to said float means for withdrawing water from said predetermined depth regardless of changes in the level of said water.
