Abstract: An in-process gage is disclosed utilizing a four bar linkage system having a floating bar in the form of a bellcrank with an active feeler connected to the bellcrank and engageable with the workpiece surface. A fixed feeler is attached directly to the gage body.

The four bar linkage system provides for precise rotation of the active feeler with virtually zero backlash enabling a gage to be constructed that is relatively thin to fit into narrow working envelopes.
