When flying as a biplane, the upper wing could be prevented from rotating by braces connected to its pylon. When rotating, the wing then assumed the character of an autorotative system." nice pic of one here: http://1000aircraftphotos.com/Garber/750.htm “In the Herrick design, a symmetrical airfoil-shaped rotor was mounted on a horizontal hinge about which it could rotate within certain limits.
