Stator rotor tools

Claim 1

A tool for installing and removing arcuately shaped segments relative to the concave surface of a semi-cylindrically configured case component wherein said segments comprise a plurality of blade elements respectively disposed along radii extending inwardly toward a central axis of said case component and wherein said segments are slidably interfittable in a plurality of parallel circumferential "T" slots within the concave surface of said case component such that said blade elements extend inward through the openings of said "T" slots, said tool including: a base member; retaining means on said base member for releasably securing said semi-cylindrical case component therein; frame means movably mounted on said base member for reciprocal motion along the central axis of said base member whereby it may be positioned in selective alignment with each of said "T" slots; a torque shaft mounted on said frame means in coaxial alignment with said central axis of said case component; a torque arm pivoted on and extending radially outward from said torque axis; and finger means on the outward end of said torque arm for interfitting with said blade elements on said segments by moving said frame means along said base member such that said torque arm is selectively positionable adjacent each of said segments in each of said "T" slots, said finger means interfitted with said blade elements by slight further additional movement of said frame and said torque arm to effect the desired intermeshed relationship, whereby application of torque to said torque shaft will apply a relatively uniform force to each of said blade elements of said segments within any of said parallel circumferential "T" slots in said case component in accomplishment the installation or removal of said segments.
