Digital taper/parallel gauge

A device for measuring the distance between two opposing surfaces, comprising:

• a wedge-shaped base section having an upper surface and a lower surface, a substantial portion of which is of a cross-section of less than 0.25" in width;
• a digital read-out having means for measuring and displaying a translational displacement of a linear-scale slider, said displacement measuring means fixedly secured to a portion of said base;
• a substantially flat, linear-scale slider means operatively associated with said displacement measuring means;
• said slider means being freely movable with respect to said displacement measurement means and capable of substantially unimpeded translational displacement with respect to one surface of said base;
• said displacement measuring means indicating the amount of translational displacement on said digital read-out of said slider means with respect to said base.

A combination taper/parallel gauge device, comprising:

• a wedge-shaped base member having a substantial flat portion of relatively narrow cross-sectional profile with respect to its height, and having a predetermined slope angle between two surfaces forming said wedge shape;
• a slider portion freely movable along a first surface of said two surfaces;
• and
• slider displacement digital read-out means for measuring and displaying movements of said slider portion with respect to said base portion, said slider displacement digital read-out means fixedly secured to said first surface of said base portion.
