U.S. Patent 3,216,423 to George B. Blonsky and Charolette E. Blonsky.
Patented November 9, 1965. Accessed via this site. Below the fold are the claims, if you can read them without wincing...

What is claimed is:

1. Child delivery apparatus comprising a centrifuge, means for supporting said centrifuge for rotational movement about a vertical axis, means for holding the patient's body against dislodgement by the centrifugal forces created in such rotational movement, with her body disposed radially of said vertical axis in proper attitude for delivery of the child and with her head located at or near said vertical axis, said holding means including means for securing the patient's body in place on said centrifuge, means for supporting the patient's limbs in child bearing position against the centrifugal forces, and means for supporting the abdomen against such forces, means connected to said supporting means for rotating said centrifuge, means controlling said rotating means to precisely control the rate of revolution of said centrifuge by said rotating means, and means for applying braking action to the revolving centrifuge.

2. Child bearing apparatus such as defined in claim 1, in which said means for supporting the patient's limbs, include means engaging and supporting the thighs of the patient, and means for holding the feet in place.

3. Child bearing apparatus such as defined in claim 2, in which said supporting means additionally include means providing handholds for the patient.

4. Child bearing apparatus such as defined in claim 1, including a detachable stretcher for carrying the patient to and from said centrifuge, and means positively connecting said detachable stretcher to said centrifuge to form a unitary device, said holding, and limb and abdomen supporting means being mounted on said detachable stretcher.

5. Child bearing apparatus such as defined in claim 1, including means on said turntable for counter-balancing the weight of the patient thereon, said counter-balancing means including a plurality of containers adjustably loaded with a weighting material to vary the weight thereof, and means for securing said containers so said centrifuge.

6. Child bearing apparatus such as defined in claim 1, including means located between said limb supporting means in position to receive the discharged infant, said infant receiving means being connected to and supported by said limb supporting means.

7. Child bearing apparatus such as defined in claim 1, including means enclosing said centrifuge for exclusion of personnel during the rotating movements of said centrifuge and having an entry opening closed by a gate, and means controlled by said gate for controlling the operation of said centrifuge.

8. Child bearing apparatus such as defined in claim 1, in which said holding means includes detachable stretcher means having a body supporting portion of sufficient length to enable the patient's head to be located at or near said vertical axis of said centrifuge, and means for attaching said stretcher means to said centrifuge against dislodgement thereof in a radial direction with relation to said vertical axis by the centrifugal forces.

9. Child bearing apparatus such as defined in claim 8, in which said attaching means comprises means for connecting the foot end of said stretcher means to said turntable, and means for supporting the head end of said stretcher means raised with relation to the foot end thereof so that said stretcher is in an inclined position relative to said vertical axis.

10. Child bearing apparatus such as defined in claim 9, in which said foot end attaching means pivotally connects said stretcher means to said turntable, and in which said head end attaching means is selectively operable to support the stretcher means at a plurality of given inclinations relative to said vertical axis.

11. Child bearing apparatus such as defined in claim 8, in which said attaching means supports the head end of said stretcher means for pivotal movement about a horizontal axis which intersects said vertical axis, the foot end of said stretcher means being unattached so that said stretcher means automatically assumes different inclinations at different rotational speeds of said turntable above a given rotational speed thereof.

12. Child delivery apparatus comprising a turntable, means for supporting said turntable for rotational movement about a vertical axis and enabling a patient to be positioned in child bearing position on said turntable radially of such vertical axis and with her head located in the proximity of the center of rotation of said turntable, means connected to said supporting means for rotating said turntable at given controlled rotational speeds, means connected to said turntable for holding the patient's body on said turntable in said radial position against dislodgement relative thereto by the centrifugal forces created by the rotational movements of said turntable, means connected to said turntable for preventing undesirable distortion of certain parts of the patient's body under such centrifugal forces, and means for receiving the child delivered by the patient.

13. Child bearing apparatus such as defined in claim 12, including means controlled by the delivery of the child into said receiving means for controlling the operation of said rotating means.

14. Child delivery apparatus comprising a turntable, means for supporting said turntable for rotational movement about a vertical axis and enabling a patient to be positioned in child bearing position on said turntable radially of such vertical axis and with her head located in the proximity of the center of rotation of said turntable, means connected to said supporting means for rotating said turntable at given controlled rotational speeds, means connected to said turntable for holding the patient's body on said turntable in said radial position against dislodgement relative thereto by the centrifugal forces created by the rotational movements of said turntable, said holding means including detachable stretcher means having a body supporting portion of sufficient length to enable the patient's head to be located at or near the center of rotation of said turntable, and means for attaching said stretcher means to said turntable against dislodgement thereof in a radial direction with relation to said vertical axis by the centrifugal forces, means connected to said turntable for preventing undesirable distortion of certain parts of the patient's body under such centrifugal forces, a flexible receiving member detachably connected to said stretcher means and arranged to receive the child delivered by the patient, and means arranged to be operated by the weight of the child contained in said receiving member to control the operation of said rotating means.
