This 1963 patent gives detailed plans on "facilitating the birth of a child by centrifugal force."

Because "civilized women" are less active during their pregnancy than "primitive women," they often have more trouble with childbirth. In attempt to create "less stress to the mother," the mother is strapped into the device (above) and spun around to create centrifugal force to propel the baby out. The "infant reception net" is padded with cotton and the baby's weight may be designed to to "activate an electric bell, announcing the event." Source
