Abstract

720,802. Turbine and compressor blades. PARSONS & CO., Ltd., C. A. March 10, 1953, No. 6628/53. Class 110 (3). In a turbine or compressor rotor in which blades having roots formed integrally therewith are mounted in serrated circumferential grooves, the closing packing piece is made in two parts a, b which when in position in the rotor groove and secured form a packing piece identical in shape and outside dimensions with the normal blade packing pieces. The lower part a is formed with a threaded hole and the upper part b with a plain countersunk hole, the two parts being secured together by means of a bolt c. The oblique surfaces on the two parts are parallel to the corresponding surfaces of the serrations h, j. The bolt is locked in position, for example, by peening metal surrounding the head into knurls provided on the side thereof.
