Abstract
28,602. Mayrow, J. J. Dec. 7. Screw propellers for aerial machines are constructed by assembling lengths of flexible metal of U, V, T, or X cross-section. Figs. 19 and 20 show the manner of constructing a propeller, in which the rods A are passed through oval rings B, and are clamped to the central collar f by shaped plates g. The blades may be covered with canvas.
