"Vintage Machinery" entry for Westinghouse Electric & Manufacturing Co.

A gage for determining alignment of a turbine rotor blade in an assembly position on a turbine rotor. The gage includes a precision base for positioning on the rotor surface adjacent a blade to establish a tangent line perpendicular to a rotor radial line through the center of a slot in which a blade is disposed. A standard extends from the base and carries a first contact for positioning against a low portion of the blade and a second measuring contact for positioning against an upper portion of the blade. The measuring contact provides an indication of blade misalignment.
