Abstract
Abstract A method of making snow out of water wherein the water is delivered from underground through a conduit to a discharge nozzle positioned above the ground and there discharged into the ambient atmosphere as a spray of discreet water particles when the atmosphere has a temperature lower than the freezing point of water. Air is also delivered under pressure through a conduit from underground independently of the water conduit to an air discharge orifice above the ground where it is discharged in the form of a jet into the ambient atmosphere such that it is directed into the throat of the water spray to produce snow. The delivered air is continually warmed to above the freezing temperature of water for its entire length of delivery above the ground with the heat generated from the water being delivered to its point of discharge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A method of making snow comprising the steps of: supplying water under pressure to a point of discharge above ground; discharging the supplied water through a nozzle into the ambient atmosphere in the form of a spray of discreet water particles when the atmosphere has a temperature lower than the freezing point of water; independently supplying air under pressure to a second point of discharge above ground; discharging the supplied air under pressure into the ambient atmosphere in the form of a jet directed into the throat of said sprayed water to produce snow; and continually insulating said air supplied to said second point of discharge for at least substantially its entire supply length of exposure above ground by coextensively surrounding the same to said point of discharge with said water supplied under pressure.
Claim 2
Independent Claim
134 words
A method of making snow comprising the steps of: supplying water under pressure to a point of discharge above ground; discharging the supplied water through a nozzle into the ambient atmosphere in the form of a spray of discreet water particles when the atmosphere has a temperature lower than the freezing point of water; independently supplying air under pressure to a second point of discharge above ground; discharging the supplied air under pressure into the ambient atmosphere in the form of a jet directed into the throat of said sprayed water to produce snow; and continually insulating said air supplied to said second point of discharge for at least substantially its entire supply length of exposure above ground by coextensively surrounding the same to said point of discharge with said water supplied under pressure.
Claim 3
Dependent Claim
23 words
The method of claim 1 including the step of directing said water spray discharge upwardly at an angle of approximately 45° from horizontal.
Claim 4
Dependent Claim
15 words
The method of claim 1 including the step of horizontally rotating said water spray discharge.
Claim 5
Independent Claim
164 words
The method of making snow out of water comprising the steps of: delivering water above its freezing temperature under pressure through a conduit from underground to a discharge nozzle positioned above the ground, discharging said delivered water through said nozzle into the ambient atmosphere as a spray of discreet water particles when the atmosphere has a temperature lower than the freezing point of water, delivering air under pressure through a conduit from underground independently of said water conduit to an air discharge orifice above the ground, discharging said delivered air in the form of a jet from said orifice into said ambient atmosphere and directing said air jet into the throat of said water spray to produce snow, and continually insulating said air conduit to maintain the temperature thereof above the freezing temperature of water for at least substantially its entire length of delivery above the ground by coaxially and coextensively surrounding said air conduit to said point of discharge by said water conduit.
Claim 6
Independent Claim
164 words
The method of making snow out of water comprising the steps of: delivering water above its freezing temperature under pressure through a conduit from underground to a discharge nozzle positioned above the ground, discharging said delivered water through said nozzle into the ambient atmosphere as a spray of discreet water particles when the atmosphere has a temperature lower than the freezing point of water, delivering air under pressure through a conduit from underground independently of said water conduit to an air discharge orifice above the ground, discharging said delivered air in the form of a jet from said orifice into said ambient atmosphere and directing said air jet into the throat of said water spray to produce snow, and continually insulating said air conduit to maintain the temperature thereof above the freezing temperature of water for at least substantially its entire length of delivery above the ground by coaxially and coextensively surrounding said air conduit to said point of discharge by said water conduit.
Claim 7
Dependent Claim
27 words
The method of claim 4 including the step of delivering said water and air underground below the frost line to the area underlying their points of discharge.
