Description: Patent for a new and improved refrigerator. This design is "for use without ice, the cooling effect being secured by the evaporation of water. Consequently the apparatus will be most effective when exposed to a current of air. The apparatus is formed with a suitable framing, having its sides closed in with wire-gauze to permit the free circulation of air, and at the same time exclude insects and the like. At one side a door affords access to the interior of the refrigerator, and legs serve to hold its bottom above the floor or other support on which the refrigerator stands" (lines 16-28).
