Abstract

5155. Morcom, R. K., and Belliss & Morcom. Feb. 29. Blades, fixing. Turbine blades b are formed with root pieces a having the conformation of a half of a disk-annulus. Portions a<1> of the roots are cut away to enable the blades to be nested in an undercut groove in the rotor or stator. To cover the vacant spaces in the grooves, a saddle-shaped cover-plate e, Fig. 5, of thin metal is fitted between each pair of blades and is secured by tongues e<4> engaging lateral slots in the sides of the grooves. The blades, together with their roots, may be turned out of lengths of tubing, each of which forms four blades after being cut axially and laterally.
