Claim 1
Independent Claim
173 words
An electronic tool gage device for measuring the length and/or diameter at selected points of tools used in machine tools, the gage device comprising a chassis within a portable cabinet, a column affixed to said chassis, a tool socket affixed to said chassis for receiving tools whose length and/or diameter is to be measured, a slidable carriage adapted to be moved vertically on said column, air bearings mounted on said carriage to give friction free movement between the said carriage and said column, a counter weight to balance said carriage, said carriage supporting a horizontal slidable arm, said carriage having air bearings to give friction free movement between the said arm and said carriage, a first sensing device mounted on said carriage for measuring the length of tools relative to said tool socket, a second sensing device mounted on said arm for measuring the diameter of tools relative to the center line of said tool socket, said sensing devices moving as a single unit, and means for visually displaying length and/or diameter data.
