378,148. Fluid bearings. SPERRY GYROSCOPE CO. Inc., Manhattan Bridge Plaza, New York, U.S.A.-(Assignees of Gillmor, R. E. ; 17, East 89th Street, New York, and Wittkuhns, B. A.; 5, Garden Place, Chatham, New Jersey, both in U.S.A.) June 22, 1931, No. 18090. Convention date, June 26, 1930. [Class 12 (i).] A gyroscope comprises a ball-like rotor supported in a cup on a self-generated air film. The rotor is spun by electric induction. In the gyro vertical shown, the rotor 12 is supported in a spherical cup 13 adjustably mounted in a spider 20 fixed to the gimbal 21. When starting up the rotor compressed air is supplied through hollow gimbals 22, 21 and passage 14 to the cup but is shut off when the ball 12 has gained speed, a supporting film of air being then maintained by rotation of the ball. |
