Abstract
Abstract A fire fighting device having a funnel shaped jacket that attaches to a rib framing system that is strapped around a bulk storage tank, the ribs attached to a relief channel located at the base of the tank, the jacket is held away from the tank shell by the ribs, the void created between the funnel jacket and tank shell is the waterway, fire stream cooling water is collected at the top of the tank by the funnel, the water is then gravity fed through the waterway, the flow rate of the water is controlled by the size of the relief ports located in the relief channel. As the water travels across the face of the tank within the waterway, it absorbs the heat radiated into the tank by an outside heat source. The heat transferred water enters the relief channel through inlet ports. The heated water is then released outside the waterway system through relief ports. Cool fire stream water enters at the top of the funnel; heat transferred water exits the system at the base of the tank.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
175 words
A water collecting and distributing protective jacket in combination with a storage tank, comprising: a plurality of channel members substantially surrounding the storage tank, each channel member having means for receiving and and loosely holding in position an edge portion of a jacket plate component at a distance from the tank to create a void between the jacket and the storage tank, each channel member having a plurality of side openings to permit water to flow from a channel member into the void, a funnel positioned on top of the water jacket forming an enclosure for collecting water and having means for permitting communication of water flow from the enclosure of the funnel into the void, the funnel having a horizontal sectional demension at least equal to a horizontal sectional dimension of the storage tank, and a horizontally disposed channel member near the lowest portion of the jacket in communication with the void, the horizontally disposed channel member having a plurality of relief ports to permit water flowing through the void to exit the jacket.
Claim 2
Dependent Claim
175 words
A water collecting and distributing protective jacket in combination with a storage tank, comprising: a plurality of channel members substantially surrounding the storage tank, each channel member having means for receiving and and loosely holding in position an edge portion of a jacket plate component at a distance from the tank to create a void between the jacket and the storage tank, each channel member having a plurality of side openings to permit water to flow from a channel member into the void, a funnel positioned on top of the water jacket forming an enclosure for collecting water and having means for permitting communication of water flow from the enclosure of the funnel into the void, the funnel having a horizontal sectional demension at least equal to a horizontal sectional dimension of the storage tank, and a horizontally disposed channel member near the lowest portion of the jacket in communication with the void, the horizontally disposed channel member having a plurality of relief ports to permit water flowing through the void to exit the jacket.
