  • For several years as of this writing, stories have circulated on the internet about an odd, perhaps comical idea: a machine that spins a woman in circles, thus using centrifugal force to aid in childbirth. For example, in 2011, the feminist blog Jezebel reported: The patent for the machine does in fact exist and can be found by searching the website of the U.S. Patent and Trademark Office. A patent for the so-called Apparatus for Facilitating the Birth of a Child By Centrifugal Force was granted to New York residents George and Charlotte Blonsky on Nov. 9, 1965. The purpose of the device was to provide gentle aid to a woman in giving birth by swirling her around fast enough to create enough force to help propel the baby out. A rather not-gentle-looking sketch of a nude woman strapped spread-legged into a large piece of machinery accompanied the patent. However, we found no evidence that this contraption was ever built or put to use. (en)
