Domelere refrigerator
Domelere was one of the first domestic electrical refrigerators, invented by Frederick William Wolf Jr. in 1913 and produced starting in 1914 by Wolf's Mechanical Refrigerator Company in Chicago. Several hundred units were sold, which made it the most commercially successful product out of several competing designs of its time. The unit replaced the block of ice in the icebox with an electrical-powered cooling device, and was completely automatic.
