Abstract
305,473. Forge et Usinage de MÚtaux LÚgers, (Assignees of Soc. Anon. Anciens Etablissements Chauviere). Feb. 4, 1928, [Convention date]. Screw and like propellers.-Arrangements for securing propeller blades to hubs particularly applicable to blades made of light metals or alloys which have a co-efficient of expansion markedly different from the metal of the hub comprise in one form radial wedge-section tenons 5 formed on or attached to cheeks 4 integral with the hub 1 and pressed into engagement with complimentary shaped mortices 7 cut in the blades 6 by through bolts 8 where the bolts are of metal different from that of the blades resilient washers are employed to compensate for relative expansion &c. In another form the three blades 12, Fig. 6, of the propeller are secured by tenons 14 on the hub which take into the dihedral angle between the blades.
