TODAY’S PATENT – HEAT INSULATING COVER
The HEAT INSULATING COVER was invented by Paul A Siple on the 5th of September 1950, bearing patent number US2520972A.
This present invention generally relates to protective covers and more particularly to a cover for enclosing nonanimated bodies of various sizes and shapes to protect them from flames and intense heat so constructed that it may be permanently or removably secured about the body and including means sealed within its walls for dissipating the heat therefrom under conditions of abnormal temperature. Another object of the invention is the provision of a new and improved protective cover for normally stationary cabinets, safes and other receptacles for valuables which may be constructed in sections and dismountably secured about the receptacle to be protected to provide all around protection therefor. Another object of the invention is the provision of the new and improved heat insulating cover which has a readily vaporizable substance having a high heat of vaporization non-escapably sealed Within its Walls at normal temperatures, but which is vaporized by abnormal external heat and as a vapor discharges outwardly from the walls carrying with it the absorbed heat of vaporization which is thereupon dissipated to the surroundings.
