Abstract

476,270. Composite blocks. HEINE, H., (trading as HEINE MOBELFABRIK PROPELLERWERK, H., [Firm of]). Oct. 13, 1936, No. 27799. Convention date, Oct. 22, 1935. [Class 145 (ii)] [Also in Group XXXIII] Wooden airscrews are constructed of laminae comprising alternate layers of thin laminae 22 and laminae 23 made up of rods glued together side by side in longitudinal direction. A number of laminae 1 bent at the ends adjacent their ultimate use at the hub of an airscrew are constructed with the laminae of differing thicknesses, the thickness. being disposed where the radius of curvature at the hub is smallest. The laminated block so constructed is then cut cross-wise so that there are obtained a number of rods and these in turn are assembled side by side and glued together to form the rod laminae.
