Abstract

944,326. Gibs. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 13, 1960 [June 12, 1959], No. 20226/59. Heading F2H. [Also in Division F1] A locking means for a turbine or compressor blade attachment of the shoulder type comprises an axially extending groove 8 at the bottom of the slot 6 in the rotor 5 beneath the blade root 7, a pin 1 formed on one side from end to end with a flat surface 3 and at each end with a head 4 and a locking plate 10 which extends from end to end of the slot and is bent over at the ends to engage the sides of the rotor 5, The pin 1 is first inserted in the groove 8 with the flat surface 3 facing radially outwards, then the blade root 7 is inserted into the rotor. The pin 1 is then rotated so that the surface 3 faces radially inwards and is locked in position by the plate 10 which is inserted between the pin 1 and the bottom of the groove. The ends of the plate 10 are then bent radially inwards. The body of the pin 1 may be of rectangular or other section provided the heads 4 have flat surfaces coplanar with a surface on the pin. The locking plate may have two legs and be used to lock two adjacent blades in position.
