ABSTRACT:
There is disclosed in the present application an expanding plug gage assembly adapted to being coupled either to an amplifying and indicating mechanism or to an electronic comparator which has its own size display. The plug is formed with an interior socket entered by a tapered plunger for expanding the plug. The angle of the taper on the plunger is varied to provide different degrees of primary amplification supplemented by the secondary amplification of the mechanism or comparator to which the assembly is coupled. The socket is formed so as to receive various plungers to provide different degrees of amplification from the same plug.
