ABSTRACT:
Locking structure for maintaining a set position in assembling an annular seal ring housing to a stationary inner shroud of an annular array of vane segments of a combustion turbine engine. This permits an adjustable assembly for obtaining concentricity between the seal and the adjacent rotor structure. Thus, the seal ring is mounted to the vane segments through an adjustable mounting arrangement that, upon assembly of the two, permits the seal ring to be aligned concentrically about the rotor. Once concentricity is obtained, the mounting components must be locked in such position to maintain such concentricity. The present invention provides a bracket attached to the adjustable mounting structure to lock it in the set position.
