Inventors and Patents From the City of Nashville
Inventors in the City of Nashville are an important part of the local economy. In fact, many inventors have made their homes in the area. Some of them are well-known in the world. Some have even been recognized as national treasures. Some are even considered legends by their peers.
Crosthwait invented automatic refrigeration system for long-haul trucks
In the early 1930s, two black men with a love for trucks came up with a way to keep long-haul trucks cool without relying on human power. Their inventions included an automatic refrigeration system for long-haul trucks and a self-starting gas engine. The inventions also led to the creation of a vacuum pump and an improved boiler system. The inventions of these two men eventually led to their induction into the ASHRAE, or American Society of Heating, Refrigeration and Air Conditioning Engineers. Their discoveries laid the groundwork for the modern central air systems. They were the first African-Americans to win this honor.
Crosthwait was also an accomplished writer and mechanical engineer. He invented many innovative heating systems and was a prominent figure in the field of air-conditioning. His inventions were applied to high-profile projects, such as Radio City Music Hall. In fact, Crosthwait was awarded more than 35 US patents and 80 foreign patents for his work. He also published a manual on heating with water and contributed to HVAC codes.
Crosthwait was also a member of numerous national organizations, including the American Society of Heating Engineers and the American Chemical Society. After retiring from his job with the Dunham Company in 1969, he taught courses at Purdue University. Crosthwait died at age 71 in West Lafayette, Indiana.
Frederick Jones is another African-American inventor who received over 60 patents. His inventions included a roof-mounted refrigeration device that eliminated the risk of food spoilage in long-haul shipments. Other inventions by Jones included a self-starting gas engine, a box office that delivered tickets, and a refrigerator for military kitchens.
Phelps contested Thomas Edison’s train telegraphy patents
In the early 1900s, Thomas Edison was the first to use train telegraphy. He developed the technology in 1893, but a lawsuit claiming infringement against his train telegraphy patents was filed against him by the City of Nashville. In this case, Edison won. He was awarded the gold Albert Medal by the Royal Society of Arts.
Edison decided to use his inventive talents on things that served actual human needs and were in high demand. He was criticized by publicists including Carroll D. Wright, the U.S. Commissioner of Labor and a well-known publicist in Boston. Wright described Edison as an uncouth, tobacco-chewing genius, but one who possessed a deep intellectual talent.
Thomas Edison was an avid reader. He would buy books in auctions and second-hand stores. He once purchased twenty unbound volumes of the North American Review for two dollars. He would carry them to his telegraphy office. He began his daily commute at three in the morning with ten volumes on his shoulder.
Thomas Edison’s mother was well educated and attractive. Born in the early 1800s in Chenango County, New York, she was the daughter of a Baptist minister and an old Revolutionary soldier. Her father, Ebenezer Elliott, was of Scotch descent. He later settled in Stonington, Connecticut, and married Mercy Peckham, a Scotch Quaker.
While Thomas Edison was a serious telegrapher, he was deeply in debt for his embryonic inventions. The next step for Edison was to move to New York. By this time, he had gained valuable business experience.
Thomas Edison was an innovator who helped to bring electric light to the masses. He also invented the train telegraph. But when he was trying to patent the device, he was faced with legal trouble. He had to prove that it was an improvement over existing technology.
Edison had a passion for chemical experimentation. During the day, he studied and experimented. His day job would not allow him to study and experiment as much as he wanted. Edison needed sleep to stay healthy.
During this time, Thomas Edison did not spend much time in Cincinnati. Instead, he shifted to Detroit. This move may have been due to his restlessness. In addition, the Civil War had left many cities in the South in ruins, and many Civil War veterans were finding it difficult to rebuild the South.
Crosthwait invented automatic ball launcher
David Crosthwait was an African-American inventor who was a recognized authority in the fields of ventilation, air conditioning, and heat transfer. He was born in Nashville, Tennessee on May 27, 1898, and raised in Kansas City, Missouri. At the time of his birth, African-American men were not highly respected in the sciences, and Crosthwait struggled to succeed in his field. Ultimately, he graduated from Purdue University in 1913 with a Bachelor of Science (BS) in engineering, and in 1920 he earned his Master of Science in mechanical engineering at Purdue. After completing his studies, Crosthwait worked as a Research Engineer at the Marshall Engineered Products Co. and he later became a Professor of Mechanical Engineering at Purdue University.
An automatic ball launcher 100 includes a housing 110 with an upper and lower end. The upper end supports the handle 116, and the lower end 114 supports the mechanical components. The upper and lower ends are connected by pivot connection points 432, 433 respectively, which form an axis of rotation of the device.
