From Wikipedia and he is also mentioned in a booklet about African American inventors and scientists that I got from Philadelphia's African American museum decades ago when I took my son there.
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.
[1] Jones innovated mobile
refrigeration technology. He received 61 patents, 40 for refrigeration technology.
[2] He co-founded
Thermo King and also served as a
Sergeant in
World War I.
[1][3]
After military service with in World War I, Jones returned to Hallock. He worked as a mechanic while learning about electronics. He built a transmitter for the town's first radio station.
Refrigeration[
edit]
Around 1938, following a request by Numero, Jones began designing the Thermo Control Model A automatic truck refrigeration unit.
[15] Jones designed the portable air-cooling unit for trucks carrying perishable food to prevent spoilage.
[8][11] The Model A refrigeration equipment was attached to undercarriages of trucks. Chilled air was transported to the inside of the trailer via refrigerant tubing.
[14] 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.
[14][16] In 1939, Jones filed for a patent for the Model A and received a patent for it on July 12, 1949.
[14][17]
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.
[14][15] 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.
[14]
Other inventions[edit]
He also developed a portable x-ray machine.
[4][11][15] He also developed an early prototype of a snowmobile. It was a "snow machine" that attached skis to the undercarriage of an airplane fuselage and attached a propeller, and a sound track synchroniser (later selling the patent to RCA).
[4][15] A movie-ticket dispenser, and an early radio service for local doctors were also counted among his inventions.
