Abstract
A head assembly is provided for use in a bore gauge and is adapted to actuate either a mechanical readout, such as a dial indicator, or an electrical readout, such as a linear variable differential transformer connected to a digital display. A U-shaped centralizing arm pivoted to the head body is provided with a pair of floating centralizing ball contacts. A first measuring ball contact is mounted at the outer end of a rack and pinion extensible stem adapted to be adjusted as to radial extension and a second measuring ball contact is mounted on a resiliently mounted finger which drivingly engages a transfer rod. The transfer rod is operatively connected to the readout device whether a dial indicator or an LVDT. A ball and groove driving arrangement is provided between the transfer rod and the pivotal finger.
