Abstract

11,706. Fraser & Chalmers, and Pochobradsky, B. F. May 16. Blades.-The rivets which secure the shanks of the blades to the turbine rotor are arranged on one and the same pitch circle, and each rivet is shared between two adjacent vanes. Short and light shanks may consequently be employed. The shank b of the blade a may be solid, Fig. 1, and is provided with recesses c, d or the same pitch circle registering with similar recesses in adjacent blade shanks, each rivet thereby holding two adjacent vanes. The shank b, Fig. 2, may carry a curved flange e at the rear of the blade, the back of the flange abutting against the next blade. Alternatively, this flange may be disposed in front of the blade. The invention is applicable to a forked shank f, Fig. 5, which may similarly be fitted with a flange. A modified form of blade having a shrouding i is shown in Figs. 9 and 10 secured by its forked shank f astride a web j.
