Abstract

4068. Leitner, H. March 15. [Cognate Applications, 6198/15, 9472/15, 11,285/15, and 12,179/15.] Screw propellers.-In hollow propellers particularly designed for aircraft and made from sheet metal plates n joined at the edges, metal liners b having one or more stiffening ribs extend through or across the hub from one blade to another. The boss c is of spool shape and its flanges d are shaped to conform for a certain distance with the normal shape of the blades where they join the boss which is recessed. Distance pieces g having lugs h, i stiffen the walls of the plates a.
