Abstract
Abstract The present invention relates to a method of preventing the spread of and extinguishing a fire in a building structure. By the present invention a plurality of holes are formed in the roof of the building structure positioned transversely to the path of the fire and a sprinkler nozzle apparatus is placed within each of said holes so that water flowing through the sprinkler nozzles is directed into the building structure. Each of the sprinkler nozzles is connected to a source of water, and water is caused to flow from the source through the sprinkler nozzles into the building at a rate sufficient to prevent the fire from spreading while the fire is extinguished.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A method of preventing a fire from spreading in a building structure having walls and a roof comprising the steps of: creating a plurality of holes in the roof of said building structure positioned transversely to the path of said fire; placing a sprinkler nozzle through each of said holes so that water flowing through said sprinkler nozzles is directed into said building structure, said sprinkler nozzles being connected in series by a plurality of hose lengths and to a source of water by a fire hose; and causing water to flow from the source thereof through said sprinkler nozzles and into said building at a rate sufficient to prevent said fire from spreading.
Claim 2
Independent Claim
114 words
A method of preventing a fire from spreading in a building structure having walls and a roof comprising the steps of: creating a plurality of holes in the roof of said building structure positioned transversely to the path of said fire; placing a sprinkler nozzle through each of said holes so that water flowing through said sprinkler nozzles is directed into said building structure, said sprinkler nozzles being connected in series by a plurality of hose lengths and to a source of water by a fire hose; and causing water to flow from the source thereof through said sprinkler nozzles and into said building at a rate sufficient to prevent said fire from spreading.
Claim 3
Dependent Claim
42 words
The method of claim 1 wherein said sprinkler nozzles are connected in series by a plurality of hose lengths and to said source of water by a pair of fire hoses each connected to one end of said series of sprinkler nozzles.
Claim 4
Dependent Claim
33 words
The method of claim 1 wherein each of said sprinkler nozzles is of a design such that water passing therethrough is atomized and at least a portion thereof sprayed in an upward direction.
Claim 5
Independent Claim
140 words
A method of confining a fire to a particular area of a building structure having walls and a roof comprising the steps of: forming a plurality of holes in the roof of said building structure positioned in a line transverse to the direction of spread of said fire and at a point just in front of said fire; placing a sprinkler nozzle in each of said holes so that water passing through said sprinkler nozzles is directed into said building structure, said sprinkler nozzles being connected in series by a plurality of hose lengths and to a source of water by at least one fire hose; and causing water to flow from said source thereof through said sprinkler nozzles and into said building structure at a rate sufficient to prevent said fire from spreading beyond said line of sprinkler nozzles.
Claim 6
Independent Claim
140 words
A method of confining a fire to a particular area of a building structure having walls and a roof comprising the steps of: forming a plurality of holes in the roof of said building structure positioned in a line transverse to the direction of spread of said fire and at a point just in front of said fire; placing a sprinkler nozzle in each of said holes so that water passing through said sprinkler nozzles is directed into said building structure, said sprinkler nozzles being connected in series by a plurality of hose lengths and to a source of water by at least one fire hose; and causing water to flow from said source thereof through said sprinkler nozzles and into said building structure at a rate sufficient to prevent said fire from spreading beyond said line of sprinkler nozzles.
Claim 7
Dependent Claim
37 words
The method of claim 4 wherein each of said sprinkler nozzles is of a design such that water passing therethrough is atomized and at least a portion thereof sprayed in an upward direction inside said building structure.
