Abstract
307,419. Moreno, A. A. March 7, 1928, [Convention date]. Screw propellers.-In variable-pitch air screws the blades a, b are pivotally attached to the boss at e, Fig. 1 and at e<1>, Fig. 2, to their swivelling roots so as to be movable in and at right-angles to the plane of rotation. In the latter case, the roots e have pinions actuated by a rack gearing.
