Abstract

691,380. Cotters. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. June 25, 1951 [July 1, 1950], No. 16487/50. Class 89 (ii) [Also in Group XXVI] A locking device for preventing axial movement of a blade mounted in an axial slot in the periphery of a turbine or compressor rotor comprises a central portion 5 which is accommodated at the bottom of the blade slot 4, and end extensions 6, 7 of width not greater than the circumferential width of the bottom of the blade slot. The end extensions are bent so as to bear at each end against the blade root and rotor. The locking device may comprise a rectangular strip of sheet metal or two such strips arranged side by side at the bottom of the blade slot. The strip may be longitudinally slotted at the ends to provide three tabs 8-13 as in Figs. 1 and 2 or two tabs at each end which are bent in opposite directions. The device may be formed by pressing or stamping and the extension or tab at one end may be bent before insertion. Specification 672,401 is referred to.
