ABSTRACT:
A front gauge which has a pair of arms (20) attached to a machine tool with a front and rear head assembly movably positioned thereon defining a pair of indexing members (34) providing an adjustable measurement. The head assemblies have a front head (32) connected by springs in bias with a positioning screw (50) to a rear head (40) providing separable adjustment. A manual lever operated pin (56) in the rear head mates with one of a series of holes (22) in the arm furnishing an incremental adjustment of the head to the nearest whole number distance from the tool. The adjusting screw is rotated changing the relationship of the heads a fractional dimension, as read by a dial indicator (64) positioned on one head contiguous with the other, thereby achieving accurate measurable distances from the tool to the gauge overcoming inaccuracies of rear mounted gauges.
