Abstract

703,173. Turbine blades. ALLEN, SONS & CO., Ltd., W. H., and HAYES, C. W. Feb. 4 1952 [Feb. 7, 1951], No. 2986/51. Class 110 (3 In a turbine rotor having at least two rows of blades, the blade roots 2, 3 are secured in undercut circumferential grooves 6, 7 in the rotor and are entered through a filling aperture 8 or 9 which is closed by a closing piece 14 or 15 having an undercut formation 16 or 17 so as to engage the adjacent blade root, and also formed for undercut engagement with the sides 13 of the filling apertures. The filling apertures 8, 9 of two blade rows are formed in alignment between the two blade rows and communicate with a single recess 10 which accommodates a packing piece 18 which retains the closing pieces 14, 15 of both rows of blading. A radial hole may be drilled in the packing piece and closing pieces and a screwed plug 19 engaged therein so as to secure the packing piece, some of the material of the packing piece being forced into slots in the plug to prevent loosening thereof. Alternatively, holes may be formed near the ends of the packing piece to overlap the packing piece and the adjacent part of the rotor, screwed plugs being engaged therein.
