Abstract
Abstract A liquid filled cover for a mattress having horizontally disposed upper and lower sheets of a material having a low resistance to penetration by fire and hot objects capable of initiating fire joined at their outermost edges to form a leakproof enclosure. After filling the enclosure with a fire extinguishing liquid, the filled height of the cover is relatively small as compared to its length and breadth. The upper sheet contains a closure for adding or removing liquid and a plurality of symmetrically opposed depressions within the upper and lower sheets of the liquid filled cover provide desired shape and load supporting characteristics. A retaining means positions and retains the cover to the top surface of a mattress. The liquid filled cover when interposed between a mattress and a sleeping occupant provides protection and warning to the occupant when the cover is punctured by fire or hot objects, whereby the released liquid acts to suppress the fire and awake the occupant.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A liquid filled cover for extinguishing and preventing bedding fires in combination with a mattress said cover having a low resistance to penetration by fire and hot objects capable of initiating fire with quick release and free flow of the confined liquid internally and externally from said cover comprising: upper and lower horizontally disposed sheets of thin material having a low resistance to penetration by fire and hot objects capable of initiating fire joined at their outermost edges to form a leakproof enclosure having a shape for substantially covering the top surface of a mattress and a relatively small height as compared the the length and breath; a fire extinguishing liquid confined within said cover until caused to be released quickly and free flow when said cover is penetrated by fire and hot objects capable of initiating fire; and a closure means for adding and removing the fire extinguishing liquid from said cover.
Claim 2
Dependent Claim
153 words
A liquid filled cover for extinguishing and preventing bedding fires in combination with a mattress said cover having a low resistance to penetration by fire and hot objects capable of initiating fire with quick release and free flow of the confined liquid internally and externally from said cover comprising: upper and lower horizontally disposed sheets of thin material having a low resistance to penetration by fire and hot objects capable of initiating fire joined at their outermost edges to form a leakproof enclosure having a shape for substantially covering the top surface of a mattress and a relatively small height as compared the the length and breath; a fire extinguishing liquid confined within said cover until caused to be released quickly and free flow when said cover is penetrated by fire and hot objects capable of initiating fire; and a closure means for adding and removing the fire extinguishing liquid from said cover.
