Abstract

416,799. Screw propellers. CARLTON, W. C., 2, Oakfield Villas, Grange Road, East Cowes, Isle-of-Wight. March 25, 1933, No. 9009. [Class 114.] A screw propeller is constructed with two or more blades in place of each blade of a normal propeller, the centre line C of the channel and the course of the fluid flow between the blades is straight from H<1> to H<2> and then passes tangentially into the arc H<2> H<3>, the surfaces B, D of the blades being parallel thereto. The outer surfaces A, E of the blades may be shaped as fairings or cambered to provide further thrust. Specification 206,676, [Class 114], is referred to.
