Look what we found. This heat exchanger is horribly cracked! If this furnace continued to operate, it would be blowing CO into the home. Not good!

Key Black inventors who revolutionized electrical and HVAC systems include....

• David Nelson Crosthwait Jr. (1898–1976): A prolific inventor with 39 U.S. and 80 international patents, he designed the heating system for Radio City Music Hall and improved vacuum pumps, boiler systems, and temperature regulation devices. He was the first Black engineer inducted into the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).

• Alice H. Parker (1895–1920): Patented a revolutionary gas-powered heating furnace in 1919 that used natural gas instead of wood or coal, laying the foundation for modern central heating.

• Frederick McKinley Jones (1893–1961): Developed specialized refrigeration units for trucks and trains, revolutionizing the transportation of perishable foods and medicine.

• Lewis Howard Latimer (1848–1928): While famous for his work with Edison on improved carbon filaments for lightbulbs, he also patented an early, innovative air conditioning unit.

• Marie Van Brittan Brown (1922–1999): An inventor who developed the first,,closed-circuit television security system and home surveillance, featuring a motorized camera and remote door unlock.

• Elijah McCoy (1843–1929): Known for his automatic lubricator for steam engines, which kept machinery running continuously, leading to the phrase "the real McCoy".

On this day, May 2nd, in Black History

In 1843, Elijah J. McCoy was born. He was a Black engineer and inventor.

Born in Colchester, Canada, Elijah McCoy was one of 12 children of a family of runaway slaves who had used the Underground Railroad to escape from Kentucky. When he was 15, McCoy's parents sent him to study mechanical engineering in Edinburgh, Scotland, because that training was impossible for Blacks to get in the United States. After finishing schooling, McCoy returned to the United States, hoping to obtain an engineering job. He was forced to accept work as a locomotive fireman with the Michigan Central Railroad, shoveling coal into the engine and applying oil to the machine's moving parts.

McCoy found the work did not challenge him and sought other more productive forms of work. It had long been considered a problem that railroad engines could not lubricate themselves. In his free time, McCoy began to consider solutions to this problem, and after two years, he developed the "lubricating cup" for steam engines. The cup allowed for the continuous flow of oil on the gears, eliminating the necessity of shutting down the machine. McCoy received a patent for his lubricating device in 1872. The lubricating cup was essential to industries worldwide, and those possessing the valuable cup were said to have "the Real McCoy."

He also obtained patents for an automatic sprinkler and an ironing table, eventually acquiring 58 patents in his lifetime. Elijah McCoy, whose creative work may have inspired the phrase "Real McCoy," died on October 10, 1929. (African American Registry, 2024)
