ABSTRACT:
An economic snow making tower and method of manufacture wherein the snow making tower includes an elongated upright aluminum tower pipe which is mounted on a support. Snow making nozzles are provided at the upper end of the tower for discharge of air and water under pressure into ambient atmosphere for manufacture of snow in subfreezing conditions and air and water connectors are provided at the lower end of the tower pipe for the supply of air and water under pressure to the tower. The support includes a vertical ground support post and a steel T fitting as welded to this support cap and has three threaded connecting necks wherein the upper threaded connecting neck threadably receives the bottom end of the tower pipe and supports the tower pipe in its upright position. The air and water connectors are connected respectively to the two remaining threaded necks of the T fitting. An unthreaded sleeve extension extends coaxially over the lower end of the tower pipe to assist in support thereof from the T fitting. An efficient and effective method is also provided for manufacturing the water and air nozzles provided at the upper end of the tower pipe.
