Claim Text:
1. A locking spacer assembly for insertion into a circumferential attachment slot between platforms of adjacent rotor blades, comprising: a first end piece configured to fit into a space between platforms of the adjacent rotor blades, the first end piece comprising an outer surface, an inner surface, and a first plane oriented generally perpendicular to a radial direction, the outer surface having a profile adapted to project into the attachment slot; a second end piece configured to fit into the space between the platforms, the second end piece comprising an outer surface, an inner surface, and a second plane oriented generally perpendicular to the radial direction, the outer surface having a profile adapted to project into the attachment slot, wherein the inner surfaces of the first and second end pieces generally face each other; an actuator movable between the inner surfaces, the actuator comprising a projection, the projection comprising a first surface and a second surface formed on the projection that respectively engage the first plane and the second plane, the first and second surfaces generally perpendicular to the radial direction; and a recess defined laterally between the first surface and the second surface, radially between the first plane and the projection, and radially between the second plane and the projection.
