Axial rotatable snow making spray head and method for making snow

Abstract

A snow making spray head that can be adapted to a snow tower is disclosed. The spray head is designed to be rotatable about a vertical axis without having to rotate the tower itself so that the direction of the spray can be adjusted to effectively lay down quality snow onto the trail in an effective pattern under different wind directions.

1 . A snow making spray head comprising:
 a. a fixed cap,   b. a fixed base,   c. an adjustable rotatable hollow body fixed between said cap and said base and rotatable about its axis to fixed positions and having at least two spray nozzles positioned therein,   d. said rotatable body forming at least two internal chambers communicating with said nozzles, at least one of said channels functionally communicating with a source of compressed air in said base and at least one of said channels communicating with a source of pressurized water, and   e. said rotatable hollow body being rotatable about its axis while maintaining the communication between said chambers, said nozzles and said source of pressured water and pressurized air in said base.   
     
     
         2 . The spray head of  claim 1  wherein at least one nozzle is a nucleating nozzle. 
     
     
         3 . The spray head of  claim 1  wherein one nozzle is a nucleating nozzle and one nozzle is a water nozzle. 
     
     
         4 . A snow making spray head comprising:
 a. a fixed base,   b. an adjustable rotatable hollow body fixed to said base and rotatable about its axis to fixed positions and having at least two nozzles posited therein,   c. said head having at least two internal chambers communicating with said nozzles, at least one said channel functionally communicating with a source of compressed air in said base and at least one said channel communicating with a source of pressurized water, and   d. said hollow body rotatable about its axis while maintaining the communication between said chambers, said nozzles and said source of pressured water and compressed air in said base.   
     
     
         5 . A snow making spray head comprising:
 a. a body portion comprising a rotatable portion and a fixed portion;   b. said rotatable portion affixed to said fixed portion such that it can be rotated around a common symmetrical axis to both portions, said rotatable portion having at least two separate internal chambers in fluid communication with at least two separate spray nozzles, one of said nozzles comprising a nucleating spray nozzle and one of said nozzles comprising a water spray nozzle, said nozzles fixed in the outer wall of said rotatable portion and communicating with said chamber and the atmosphere;   c. said rotatable portion also containing at least two internal conduits that communicate with said chambers and a source of pressurized water and pressurized air; and   d. said fixed portion including a fixed axle that is functionally adapted to said rotatable portion permitting the rotatable portion to rotate around said axle.
