Gorrie Ice Machine, Patent Model

images for Gorrie Ice Machine, Patent Model
This model was submitted to the U.S. Patent Office with the application for the patent issued to John Gorrie, of New Orleans, Louisiana, May 6, 1851, no. 8080.
The model represents the first patent for a mechanical refrigerating or ice-making machine issued by the United States Patent Office. It is of additional interest in that the inventor successfully employed ice and cooled air in the treatment of tropical diseases, and for his work in this connection and the invention of the ice machine he is honored by a statue placed in Statuary Hall in the United States Capitol by the State of Florida.
The machine was designed “to convert water into ice artificially by absorbing its heat of liquefaction with expanding air.” The model, made largely of wood, is diagrammatic only. It consists of a double-acting compressor cylinder and a double acting work or expanding cylinder, the pistons of which are connected to a crankshaft designed to be turned by a steam engine or other prime mover not shown. The air compressed in the compressor cylinder was cooled by the immersion of the cylinder in cold water, the injection of cold water into the cylinder and by passing the air through a worm immersed in a tub of water. The compressed air was led to a receiver and thence to the expanding cylinder, which was surrounded by a cistern of “uncongealable” liquid. The expansion or air absorbed heat from the liquid, which was circulated to a worm in a freezing tub where the liquid absorbed heat from water in the tub causing it to freeze.
