ABSTRACT:
The present invention relates to a snap gage that compensates for any misalignment of a part which is to be measured. The gage has two opposed, independently pivotal levers between which a part may be positioned. The levers pivot according to the dimensions of the part with the resultant overall pivotal movement of the levers being realized at a ball contact that operates a linear plunger connected to a linear movement indicator. The levers are substantially L-shaped having a sensing arm and a translating arm which contacts the linear plunger. The ends of the translating arms are each chamfered with one having a flat surface and the other having a non-flat surface, such as a radial or V-notched surface to maintain alignment of the plunger.
