Abstract
181,110. Leitner, H. March 5, 1921. Screw propellers.-Hollow laminated sheetmetal blades for screw propellers have bent-over edges, the longitudinal joint or joints being formed in one or both faces or at the trailing edge. When one joint is used, the edges c, d are bent over and the joint e, Fig. 13, is a riveted lap joint. With two joints e, Fig. 3, the joints are in each face; alternatively both joints e, Fig. 12, may be in one face. The joint may be formed with a butt strap or straps, or, as in Fig. 8, be folded over and clinched. The joints may also be made by welding. In a modification, a joint is made at the trailing edge only.
