Abstract
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 Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
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.
Claim 2
Dependent Claim
140 words
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.
