Abstract

13,140. Le Dantec, L. M. June 9, 1911, [Convention date]. Drawings to Specification. [Addition to 26,722/11.] Screw and like propellers. - Comprises improvements in the screw propeller described in the parent Specification, and consists in making the inner edge 3/32 of the mean pitch, in making the outer radius within the limits of 15/32 and 8/32 The length of the screw may also be made less than the pitch where space does not permit of the full pitch being employed. The zone of 45 degrees may be arranged at the inner radius where the pitch is small, and may continuously progress to the outer edge along the screw.
