Abstract
Abstract Improved apparatus for making artificial snow by simultaneously releasing a mixture of water and air under pressure through a discharge aperture into the atmosphere. Prior to discharge, the water and air mixture is forced to impinge against the concave surface of a blocking member mounted inwardly of the discharge aperture in the path of the exiting mixture. The blocking member serves to increase atomization of the water and air mixture and reduces the quantity of compressed air required to effect coverage of a given area with the artificially produced snow. In addition, the blocking member serves to significantly reduce the operating noise level of the improved snow making apparatus.

Claim 1
Independent Claim
235 words
Improved snow making apparatus utilizing water and air to produce artificial snow, said apparatus comprising: a. a first tubular member having a first passageway therein, for admitting air thereto and an exit end, said exit end having a plurality of openings circumferentially formed in the wall thereof; b. a second tubular member positioned about said first tubular member to define a second passageway therebetween, said second pasageway communicating with said first passageway only via said plurality of openings, said second tubular member having an entrance port communicating with said second passageway for admitting water thereto; c. mixing chamber means connected to the exit ends of said first and second tubular members for permitting expansion and mixing of water and air therein; d. blocking means positioned in said mixing chamber means at the entrance thereto for breaking up and reducing the size of water droplets entering said chamber means, said blocking means including i. an inlet end communicating with said first passageway after water has been introduced thereto and mixed with the air via said plurality of openings; ii. an anvil section having a concave surface, facing said inlet end, positioned in the path of the water and air mixture; and iii. a plurality of spaced ribs defining openings therebetween joining said inlet end and said anvil section. e. discharge means connected to said mixing chamber means for discharging the water droplets to the atmosphere therefrom.
