ABSTRACT:
An inside dimension measuring gauge is disclosed having a spindle within a tubular body which actuates a plurality of contact pistons, the measurement being indicated by sensing the displacement of the spindle. A pair of opposed levers pivotally mounted to the tubular body are provided for axially displacing the spindle with respect to the tubular body upon manual application of a compressive force on the pair of levers. The pair of levers are connected to the axial spindle by a pair of movable links and are further provided with screws for regulating the permitted motion of the levers with respect to the tubular body.
