Abstract

433,989. Screw propellers. MULLER, M., 44, Hegelstrasse, Stuttgart, Germany. Sept. 14, 1934, No. 26458. [Class 114] Tractor propellers for aircraft b, d, e are mounted on concentric shafts and have diminishing diameters towards the front. The shafts are arranged so that the angle of advance of the propellers relative to each other, and their longitudinal spacing can be varied.
