Fire prevention and cooling system

Claim 1

A liquid dispensing system primarily for fire prevention whereby water may be transferred from a source to potentially combustible parts of a structure, such as a roof or side walls, the system comprising: a supply conduit communicating water from said source to a dispensing tube, said supply conduit including a filter and having a first portion thereof disposed above the peak of a roof of such structure and at least a second portion disposed perpendicular to said first portion and extending away therefrom, said second portion including an arm extending perpendicularly therefrom for partially going around an obstacle; a first dispensing tube having a plurality of openings, said tube having a generally U-shape where said U-shape has oppositely disposed arms and a connecting base portions, wherein water in any part of one arm of the U can communicate with water in any part of the other arm of the U by way of the base and wherein the arms of said U are disposed parallel to but at a lower elevation from the first portion of the supply conduit; a second dispensing tube having a plurality of openings, said second tube extending parallel to the second portion of said supply conduit; a first series of feed lines attached to said supply conduit and said first dispensing tube for permitting water to flow from said supply conduit to said first dispensing tube at relatively constant pressure from one arm of said first dispensing tube to the other arm, said first series of feed lines being staggered so that feed lines extending to one arm of said dispensing tube are out of alignment with feed lines extending to the other arm of said first dispensing tube; and a second series of feed lines attached to said second portion of said supply conduit and said second dispensing tube for permitting water to flow from said second portion of said supply conduit to said second dispensing tube at relatively constant pressure from one end of said second dispensing tube to the other wherein blockages of certain portions of said first dispensing tube does not deprive downstream sections of said dispensing tube of water.
