Abstract

Abstract A portable snow making tower including an elongated metallic water pipe or conduit having a first discharge nozzle adjacent the upper edge thereof and an air supply conduit extending substantially coextensive with and secured with the water conduit. The air conduit is provided with an air discharge orifice adjacent the upper end thereof which is positioned such that the orifice discharge air therefrom under pressure in the form of a jet stream which is directed into the water discharged from the water nozzle to form a plume of atomized water at the top of the tower for making snow. The water conduit and air conduit are positioned at an incline and supported intermediate their upper and lower ends by two legs pivotally attached to the water conduit at the upper ends of the legs, and with the bottom ends of the legs spread thereby forming a tripod configuration which may be collapsed by pivoting the legs inwardly toward the water conduit. At least one of these legs are adjustable in length to permit extension thereof to accommodate sloping ground surfaces and the bottom of the two legs are adapted for sliding along a ground surface when the tower is being towed by the bottom end of the water conduit.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 270 words
A portable snow making tower comprising an elongated water conduit having first discharge nozzle means provided adjacent the upper end thereof, water supply line attachment means at the lower end of said water conduit for supplying water therein under pressure, an air conduit extending substantially coextensive with and secured with said water conduit and having an air discharge orifice adjacent the upper end of said air conduit and said orifice positioned to discharge air therefrom under pressure which is directed into the water discharged from said nozzle means to form a plume of atomized water for making snow, air supply attachment means at the bottom of said air conduit for supplying air therein under pressure, said water conduit positioned at an incline and supported intermediate its upper and lower ends by two legs pivotally attached thereto at their upper ends and spread at their bottom ends thereby forming a tripod configuration including said water supply conduit which may be collapsed by pivoting said legs inwardly toward said water conduit, stop means limiting further pivotal travel of said legs away from said water conduit beyond an outer predetermined limit to stablilize said tripod configuration, skid means on the bottom of said legs permitting said legs to slide along a surface, tow attachment means at the bottom end of said water conduit for towing the snow-making tower on said skid means, said stop means comprising three horizontal cross-braces respectively connected between said legs and between said legs said water conduit, said braces each being readily detachable at one end and pivoted at the other end to permit folding of the tripod configuration.
Claim 2
Dependent Claim 270 words
A portable snow making tower comprising an elongated water conduit having first discharge nozzle means provided adjacent the upper end thereof, water supply line attachment means at the lower end of said water conduit for supplying water therein under pressure, an air conduit extending substantially coextensive with and secured with said water conduit and having an air discharge orifice adjacent the upper end of said air conduit and said orifice positioned to discharge air therefrom under pressure which is directed into the water discharged from said nozzle means to form a plume of atomized water for making snow, air supply attachment means at the bottom of said air conduit for supplying air therein under pressure, said water conduit positioned at an incline and supported intermediate its upper and lower ends by two legs pivotally attached thereto at their upper ends and spread at their bottom ends thereby forming a tripod configuration including said water supply conduit which may be collapsed by pivoting said legs inwardly toward said water conduit, stop means limiting further pivotal travel of said legs away from said water conduit beyond an outer predetermined limit to stablilize said tripod configuration, skid means on the bottom of said legs permitting said legs to slide along a surface, tow attachment means at the bottom end of said water conduit for towing the snow-making tower on said skid means, said stop means comprising three horizontal cross-braces respectively connected between said legs and between said legs said water conduit, said braces each being readily detachable at one end and pivoted at the other end to permit folding of the tripod configuration.
Claim 3
Dependent Claim 22 words
The portable snow making tower of claim 1 including elongation means on at least one of said legs permitting adjustable extension thereof.
Claim 4
Dependent Claim 27 words
The portable snow making tower of claim 1 including an anchoring spur at the bottom of said water conduit for anchoring said tripod configuration into the ground.
Claim 5
Dependent Claim 28 words
The portable snow making tower of claim 1 characterized in that said air conduit is enclosed within said water conduit to surround it with moving water for insulation.
Claim 6
Dependent Claim 40 words
The portable snow making tower of claim 4 including second discharge nozzle means positioned adjacent to said first discharge nozzle means and connected to the water conduit interior to provide at least one additional water discharge directed into said plume.
Claim 7
Dependent Claim 23 words
The portable snow making tower of claim 4 wherein said water conduit and said air conduit are comprised of a metallic conducting medium.
Claim 8
Dependent Claim 18 words
The portable snow making tower of claim 6 wherein said water conduit is at least fifteen feet long.
Claim 9
Dependent Claim 18 words
The portable snow making tower of claim 1 wherein said water conduit is at least fifteen feet long.
Claim 10
Dependent Claim 24 words

Claim 11
Dependent Claim 23 words
The portable snow making tower of claim 9 wherein said slide attachment is provided with clamp means to adjustably stop said sliding arrangement.
Claim 12
Dependent Claim 26 words
The portable snow making tower of claim 9 including a pick-up eye on said slide attachment to assist in the maneuverability of the portable snow tower.
Claim 13
Dependent Claim 33 words
The portable snow making tower of claim 1 wherein all the connections between said cross-braces and said legs and water conduit are respectively adjustably slidable up and down said legs and water conduit.
Claim 14
Dependent Claim 23 words
The portable snow making tower of claim 12 wherein said slidable connections are provided with clamp means to adjustably stop said sliding arrangement.
Claim 15
Dependent Claim 23 words
The portable snow making tower of claim 1 wherein said elongated water conduit, said legs and said cross-braces are constructed of tubular stock.
