Abstract: An elongated pipe conduit snow making tower, and assembly method, having an upper end spray nozzle head and pivotally supported on a support pipe for vertical inclination by a hydraulic ram jack enabling infinite non-preselected incremental inclinations. A ram safety latch automatically latch/catches the tower pipe if the jack leaks. Secondary and tertiary external flexible water hoses are selectable to feed associated spray head snowmaking nozzles, and an internal compressed air conduit feeds spray head seeding nozzles. Secondary and tertiary ball valve assemblies mounted on a water feed block are outlet coupled to their respective hoses. In drain condition turbulent primary water continually washes against a valve ball flow closure side for an anti-freezing effect. The spray head is a four-piece modular planar stack up of disks each carrying spray nozzles that all discharge forwardly away from the pipe tower in generally parallel spray patterns.

Abstract: Apparatus for and method of making snow which involves a water source, a compressed air source, a mixing chamber and an exit orifice. Compressed air and water are mixed in the chamber and then expelled into ambient air having a temperature below 32.degree. F. A continuous flow of water substantially surrounds the mixing chamber and at least a portion of the exit orifice, and the amount and temperature of this flow of water is controlled to prevent clogging of the chamber and orifice by freezing of the water and air-water mixture therein. In one form the water is circulated past the mixing chamber and a major portion thereof is fed onwardly to additional snowmaking nozzles.

Abstract: An improved snowmaking apparatus comprising a water source and an atomizing fan wherein during a snowmaking operation water is placed onto the rotating blades of an atomizing fan, the water exiting from the trailing edges of the blades as droplets, the improvement comprising providing a ducted fan behind the atomizing fan, the ducted fan during operation blowing ambient air towards and over the atomizing fan.
