Abstract

1,120,960. Axial-flow compressors; gas turbine engines. GENERAL ELECTRIC CO. June 21, 1966 [July 29, 1965], No. 27598/66. Headings F1C and F1G. Items such as pipe-line holders 64, Fig. 3, actuators and other controls and accessories are mounted on the cylindrical casing 22 of an axialflow compressor forming part of a gas turbine engine by means of a bracket 36 comprising a bridge portion 38 terminating at each end in a foot 40. Each foot 40 is formed with a counterbored hole to fit around the mounting bush 46 of an adjustable pitch stator blade 24. A nut 56 threaded on the bush 46 draws the flange 48 of the bush against a counterbored surface 52 of the casing 22 to clamp the bush and the foot 40 in place. The bracket 36 is preferably of aluminium with a steel insert 60 into which a screw 62 can be threaded to support the pipe-line holder 64 or other item. As shown, the bracket 36 may be secured to adjacent stator blade bushes or may instead be large enough to span over one or more stator blades. The bracket may comprise two bridge portions (38) and three feet (40), Fig. 6 (not shown).
