Abstract

5853. Howden, J. March 11. Blades. -Turbine blades and distance-pieces are threaded into dovetailed grooves in the rotor drum or wheel, and are locked in position by filling-pieces secured in the openings through which they are inserted. Figs. 1 and 2 show one arrangement of locking filling- pieces for use when the blades are mounted on a drum a. A special distancepiece A is provided, having a projection B fitting in a slightly tapered cross-groove in the drum. It is held in position by a piece C sliding longitudinally in the under - cut side opening; this piece is locked by a block D secured by a pin F. The side-opening is long enough to allow a distance - piece and the last two blades to be inserted after the distance-piece A is positioned. Fig. 7 shows a modification in which the special distance-piece A<2> is provided with cylindrical extensions a<2>, which fill the side-openings and through which pass the securing-pins a<3>. The piece A<2> is slightly tapered, and is inserted last. Fig. 8 shows the modification adopted when the blades are carried by a rotor - wheel A<6>. The special distance-piece A<4> is similar to A, Fig. 1, and is locked by a piece A<5>, which fills the dovetailed opening in the side of the wheel.
