Hole Angularity Gage.
Abstract
This patent application covers a gage for measuring the angularity of the centerline of straight and/or tapered holes with respect to a flat surface. A tapered pin is inserted into the tapered hole and the gage is placed over the pin and pushed against the surface of the material with the hole in it. A dial indicator provides a direct reading of the angle that the centerline of the hole varies from being perpendicular to the surface. For straight holes, an expanding collet is first inserted into the hole and then the tapered pin is inserted into the collect causing the collet to expand against the sides of the hole and provide an accurate reading on the indicator.
