Oscillating snow making tower

Abstract

An oscillating snow making tower including an oscillating fluid drive secured to the tower for horizontally oscillating the tower on its ground support pole back and forth between preset limits, and wherein, this oscillating fluid drive is powered by the water or air supplied under pressure to the snow making tower, thereby eliminating the need for access to electricity in order to oscillate the tower.

I claim: 
     
         1 . A snow making apparatus including a vertical ground support pole having bottom and upper ends with said bottom end anchored in a ground surface, a tower support sleeve coaxially received over the upper end of said ground support pole for axial rotation thereon, and an elongated pipe snow making tower having upper and lower ends with snow making nozzles adjacent the upper end and water and air inlets at the lower end thereof for connection to respective supplies of water and air under pressure from remote sources for ejection through said nozzles to manufacture snow in subfreezing ambient conditions, said tower secured adjacent its lower end to the upper end of said tower support sleeve at a vertical incline for axial rotation of said tower on said ground support pole;
 the improvement comprising an oscillating fluid drive secured to said tower for oscillating said tower on said ground support pole back and forth between preset limits, said fluid drive powered by said water or air supplied under pressure.   
     
     
         2 . The snow Making apparatus of  claim 1 , wherein said oscillating fluid drive is disposed between said elongated pipe snow making tower and said ground support pole. 
     
     
         3 . The snow making apparatus of  claim 2 , wherein said water inlet is connected to said oscillating fluid drive for driving the same with said water supplied under pressure. 
     
     
         4 . The snow making apparatus of  claim 1 , said fluid drive including said snow making nozzles as a means for driving said tower in said oscillating movement. 
     
     
         5 . The snow making apparatus of  claim 4 , including an oscillating fluid drive motor connected to rotate selected of said snow making nozzles about an axis in an oscillating manner for thereby oscillating said tower in rotation about said ground support pole. 
     
     
         6 . The snow making apparatus of  claim 4 , wherein said snow making nozzles are fixed in position on opposite sides of said tower, and including an oscillating valve for alternately supplying a dominate portion of said water under pressure to said water nozzles on opposite sides of said tower for thereby oscillating said tower in rotation about said ground support pole.
