Portable Air Conditioning Unit for Trucks
Frederick McKinley Jones

Inventor
Frederick McKinley Jones, Frederick McKinley Jones
Frederick McKinley Jones (May 17, 1893 – February 21, 1961) was an American inventor, entrepreneur, engineer, winner of the National Medal of Technology, and an inductee of the National Inventors Hall of Fame.
Jones innovated mobile refrigeration technology. Jones received 61 patents, including 40 for refrigeration technology, and also revolutionized the cinema industry by creating a superior sound system for projectors at the time. Jones co-founded Thermo King and also served as a sergeant in World War I. Due to his contributions to refrigeration technology, he is called the “Father of Refrigerated Transportation”, and the “King of Cool.”
Around 1938, following a request by a local entrepreneur Joseph A. Numero, Jones began designing the Thermo Control Model A automatic truck refrigeration unit. Jones designed the portable air-cooling unit for trucks carrying perishable food to prevent spoilage. The Model A refrigeration equipment was attached to undercarriages of trucks. Chilled air was transported to the inside of the trailer via refrigerant tubing. Because Model A was too heavy, Jones later developed the Model B. The Model B was smaller and lighter, but not durable. In 1941, Jones completed development of the Model C, which was mounted to the front of the truck. It was compact, light, and withstood road travel vibrations. In 1939, Jones filed for a patent for the Model A (US No. US2303857A) and received a patent for it on December 1, 1942. Numero sold his movie sound equipment business to RCA and formed a new company in partnership with Jones, the U.S. Thermo Control Company (later the Thermo King Corporation) which became a $3 million business by 1949. Portable cooling units designed by Jones were especially important during World War II, preserving blood, medicine, and food for use at army hospitals and on open battlefields. Model C units were manufactured for military use, following the war the units became available for commercial use.
