Abstract

10,720. Bayliff, W., Bayliff, T. D., and Draper, D. May 6. Blades.-Axial-flow turbine blades c, Fig. 1, are made of wedge-shaped cross-section so that the width of the fluid passage way is constant from root to tip. The roots comprise distancepieces b<1>, Figs. 1 and 2, and dovetail root portions b<3>, these fitting into an undercut groove e. The tips of the blades are formed with lateral portions b<2>, which, when the blades are assembled, form a shroud. Alternatively, as shown in Fig. 2, the shroud may be composite, comprising the tips b<2> and flanged rings f. The parts b<2>, b<3> are formed with radial projections and notches to ensure correct engagement with the adjacent parts. A section of blades is caused to abut against a piece j screwed in position by the action of wedge i similarly screwed on. Long blades may be formed with lateral webs c'.
