ABSTRACT:
An improved construction for securing the connecting link from the free end of a Bourdon tube to the segment gear in the geared movement of a pressure responsive instrument. An elongated flat spring clip, recessed in its center portion, has one open end from which it is longitudinally slotted inward. The opposite end is screw tapped for acting as a nut to receive a screw fastener. By a slip fit insertion of the spring clip over a controlled recess on the segment shaft, the clip is held in place in a controlled tensioned grip for captivating the nut at the fastener location of the segment gear. Should it be necessary to shift the fastener location for purposes of calibrating the instrument, the spring clip is finger slideable for relocation as required.
