Abstract

1,102,219. Rivets. GENERAL MOTORS CORPORATION. 8 Dec., 1966 [8 April, 1966], No. 64918/66. Heading F2H. [Also in Division F1] A turbine or compressor blade 14 is locked in position in an axially extending groove 18 in the rotor rim 17 by a hollow pin 28 extending through a radial bore 26 in the rim to engage a slot 24 in the blade root 16. The base of the slot is domed so that when the pin is driven into position its head 30 spreads in the circumferential direction and thus retains the pin in position. In modifications, the slot 24 may be V-shaped or trapezoidal. The pin is shearable so that the blade can be driven axially out of the groove.
