Abstract
A measurement gage includes a base having two scales at opposite site ends of the base for different ranges of measurement. A tapered feeler gage elements projects axially from each of the opposite ends, and a slide bar is movable along the base, with an indicator fixed thereto for each of the two different scales. Movement of the slide bar in each of two opposite axial directions is calibrated to respective thicknesses of the tapered feeler gage elements.
Claims14
A measurement gage comprising a base having two scales at opposite ends of said base for different ranges of measurement;
- a tapered feeler gage element projecting axially from each of said opposite ends;
- and
- a slide bar movable along and relative to said base and having an indicator fixed thereto for each of said two different scales;
- wherein movement of said slide bar in each of two opposite axial directions relative to said base is calibrated to respective thicknesses of said tapered feeler gage elements wherein said base is channel-shaped in cross section, and said slide bar is located within said base.
A measurement gage comprising a base having two scales at opposite ends and on opposite sides of said base for different ranges of measurement;
- a tapered gage element projecting axially from each of said opposite ends;
- and a slide bar movable along and relative to said base and having an indicator fixed thereto for each of said two different scales;
- wherein movement of said slide bar in each of two opposite axial directions relative to said base is calibrated to respective thicknesses of said tapered gage elements;
- wherein said base is channel-shaped in cross section, and said slide bar is located within said base;
- and further wherein one of said two different scales is adapted to measure gaps between 5 and 25 thousandths and the other of said two different scales is adapted to measure gaps between 25 and 50 thousandths.
