Let's start with the gentleman photo'd above, Frederick McKinley Jones. Jones is most known for inventing the automatic refrigeration system for long haul trucks and rail road cars in the 1940s. So when you see trucks on the highway transporting refrigerated and frozen foods, you're watching one of his inventions. Prior to this, these foods were only kept cool in trucks by loading them with ice. Jones has patented more than 60 inventions during his lifetime. Roof mounting cooling system, air conditioning unit for military field hospitals, refrigerator for military field kitchens, self-starting gas engine, a series of devices for movie theaters etc. Needless to say, Frederick M. Jones was the man. Awarded the National Medal of Technology in 1991, posthumously, Jones was the first black inventor to receive that award.
You know the thing you use to open doors, your entire life, in your home? building? store? Thank Osbourn Dorsey. Dorsey patent #210764 was described as the "door holding device" in 1878. In modern terms, the door knob. Dorsey, also, invented the door stop. ___________________________________________________________
In 1911, Nathaniel Alexander patented the Folding Chair. Per his patent, Alexander designed this chair to be used in schools, churches, auditoriums etc. Fast forward to 2022, where they are still used for his purpose and even beyond. You can literally almost spot this chair at every event.
Paul L. Downing designed a metal box with four legs in 1891, which was deemed a 'street letter box'. This was said to be created so people would not have to go all the way to the post office to mail letters. The mailbox placed in different areas would simply be more convenient. I do not have Mr. Downing pictured because the picture google has for him is also the same picture they use for another inventor. Unfortunately, I am unsure which is which. Did I mention that just a year prior, Downing patented "new and useful improvements in street-railway switches"? ______________________________________________________
George T. Sampson was the first in the U.S. to patent the automatic clothes dryer in 1892. Known as Patent #476,416, this invention was a frame that suspended clothing above a stove to dry more quickly. Sampson is credited for setting a blueprint of the clothes dryers we all use today. Prior to in 1885, Sampson patented the sled propeller.
