Single float water cooler

Claim 2

Floating water cooler apparatus for cooling a body of water by propelling a plurality of sprays of water above the surface of said body comprising a single floating support having a load waterline and a central cylindrical duct with a vertical axis, said duct providing a vertical flow passage an axial flow non-sealing impeller mounted in said duct below said load waterline with its axis coincident with the axis of said duct impeller driving means including a motor mounted above said floating support and having a downwardly extending driving shaft coincident with the axis of said impeller for driving said impeller a plurality of water conduits mounted on said floating support and connected at their inner ends to said duct above said impeller said conduits extending outwardly above the load waterline of said support with their outer ends above said load waterline upwardly directed spray nozzle means mounted on said conduits for spraying water from said impeller said water being free to drain from said conduits and said duct upon stopping of said impeller from complete drainage of said conduits.

Claim 3

Floating water cooler apparatus as claimed in claim 1 wherein said conduits extend radially outwardly from said duct.

Claim 4

Floating water cooler apparatus as claimed in claim 2 including at least four said conduits.

Claim 5

Floating water cooler apparatus for cooling a body of water by propelling a plurality of sprays of water above the surface of said body comprising a single floating support having a load waterline and a central cylindrical duct with a vertical axis, said duct providing a vertical flow passage an axial flow non-sealing impeller mounted in said duct below said load waterline with its axis coincident with the axis of said duct impeller driving means including a motor mounted above said floating support and having a downwardly extending driving shaft coincident with the axis of said impeller for driving said impeller a plurality of water conduits mounted on said floating support and connected at their inner ends to said duct above said impeller said conduits extending outwardly above the load waterline of said support with their outer ends at least at a vertical height above said load waterline as great as their said inner ends upwardly directed spray nozzle means mounted on the outer ends of said conduits for spraying water from said impeller said water being free to drain back through said conduits and said duct upon stopping of said impeller for complete drainage of said conduits.

Claim 6

Floating water cooler apparatus for cooling a body of water by propelling a plurality of sprays of water above the surface of said body comprising a single floating support having a load waterline and a central cylindrical duct with a vertical axis, said duct providing a vertical flow passage an axial flow non-sealing impeller mounted in said duct below said load waterline with its axis coincident with the axis of said duct impeller driving means including a motor mounted above said floating support and having a downwardly extending driving shaft coincident with the axis of said impeller for driving said impeller a plurality of water conduits mounted on said floating support and connected at their inner ends to said duct above said impeller said conduits extending outwardly above the load waterline of said support with their outer ends at least at a vertical height above said load waterline as great as their said inner ends upwardly directed spray nozzle means mounted on the outer ends of said conduits for spraying water from said impeller said water being free to drain back through said conduits and said duct upon stopping of said impeller for complete drainage of said conduits.

Claim 7

Floating water cooler apparatus as claimed in claim 4 wherein said conduits are arranged in the form of an H connected centrally to said duct and a plurality of spray nozzle means are mounted on each of said conduits.
