Abstract

1408616 Compressor blade fixing INGERSOLL-RAND CO 3 Nov 1972 [17 March 1972] 5967/75 Divided out of 1408615 Heading F1T The subject matter of this Specification is identical with that described in Specification 1408615, but the claims are concerned with an arrangement for mounting compressor rotor blades comprising a blade mounting ring having a central aperture for mounting the ring about a rotor shaft; at least one rotor blade having a mounting head on one end thereof; the head and the ring having boreholes for receiving means for pivotally securing the blade to the ring, and the head having means on each side for accommodating a vibration-damping element.
