A flexible pointer is provided for use as a movable indicator, hand or arm on such devices as dial indicators, movable arms for electrical contacting devices, and the like. The pointer is comprised of a pair of strips of spring material joined at their upper ends and spread apart at their lower ends in a generally triangular shape, the outer free end being the indicating portion, while the wider, inner end is connected to a pivot or other movable support. The triangular configuration allows the pointer to bend due to rapid acceleration or overtravel and to return to its original shape without damage.

An attachment is provided for mounting over the nozzle tip of an air gauge follower system to permit use of the system in gauging thin, fragile sheet stock or work having a rough or irregular surface. The attachment includes a thin, flexible diaphragm mounted by means of a collar over the tip of the nozzle in the air gauging apparatus. The diaphragm normally closes the nozzle port and expands out against the work when air pressure is applied through the nozzle forming the air gap which controls the measuring device.
