Abstract

528,439. Propellers. GHIRARDI, L. May 8, 1939, No. 13669. Convention date, May 13, 1938. [Class 114] [Also in Group XXVI] Vanes 8 of a fan impeller or a propeller are hinged freely on axes 6 which are substantially inclined to both the radial and axial directions and to radial planes through the hinges. The body 3 may have the form of a zone of a spherical or paraboloidal surface as described in Specification 310,101, [Class 114 (i)]. The vanes may be helicoidal or plane and the body may have spiral ribs. The Specification as open to inspection under Sect. 91 comprises also a discoidal body with radial hinges for the vanes. This subjectmatter does not appear in the Specification as accepted.
