On This Day

Refrigeration In 1879, African-American Thomas Elkins patented a refrigerating apparatus (No. 221,222) designed for chilling or cooling food, or even, according to the patent, human corpses. A porous chilling box enveloped in fabric rests on a grated floor through which a circulation of air aids the evaporation of water supplied from a trough to the fabric. As the water evaporates, latent heat is withdrawn from the chilling box. He also held patents for a table (a dining and ironing table combined with a quilting frame, 20 Feb 1870, No. 100,020) and a commode (9 Jan 1872, No. 122,518).
