Abstract
262,860. Harper, A., and Harper, S. A. Sept. 16, 1925. Screw propellers.-Blades of screw propellers are attached to the boss at the forward end and are concave on the driving face with a reverse curve at the inner edges, the outer edges being at an increasing distance from the axis from front to rear. The two blades 6 are secured to the boss 1 at the forward ends and extend rearwardly almost parallel to the axis. The blades have a concave driving face with a small reverse curvature 10 along the inner edges. The distance across the tips 9, 9 is greatest at the far end. In forming the blades from a sheet, the centre rectangular portion 13 is cut away, the inner edges are bent oppositely to form the reverse curves and the main portion then bent oppositely out to the edges 16, 17.
