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.

First Claim:
Show all 6 claims
I claim:     1. A front position locating gauge for a machine tool comprising:
  • (a) a support arm having a plurality of equally spaced holes therewithin, removably joined to the front of the machine tool providing an extended mounting surface;
  • (b) a front head having means to slide on said arm and an indexing member extending therefrom, the head slideably engaging the arm providing a stop on the end of he indexing member a linear alignment with the arm; said front head further having a dial indicator arm fastened to the top of the head providing a uniform measurable surface for engaging the indicating means;
  • (c) a rear head having means to slide on said arm, adaptably communicable with the front head for sliding on the arm in concert therewith;
  • (d) positioning means integral with said rear head decisively engaging a selected hole in the arm providing a predetermined location of the heads relative to the tool processing member;
  • (e) adjusting means joining the front and rear heads in a manual yielding manner within a fixed increment of measure allowing a precise distance from one head to the other to be generated; and,
  • (f) indicating means integral with the rear head and contiguously engaging the front head for reading the linear distance therebetween, the gauge providing an adjustably precise distance between the end of the indexing arm and the machine tool by positioning the rear head using the nearest hole in the arm for the approximate location and making the final locational adjustment by sliding the front head to the exact position as verified by the indicating means.
