Abstract
This disclosure relates to a toolmaker's square gage or try square and is adapted to indicate the deviation from square of two surfaces of a part. The square gage includes a horizontal beam having a fulcrum point or edge adjacent one end, a fixed upwardly extending gage post secured to the beam, in fixed relation, and a feeler gage secured to the beam, spaced from the post. The gage includes a gage feeler or plunger which engages the supporting surface of the gage and a dial indicator which indicates the linear movement of the feeler; such that the gage reading is proportional to the angle of inclination of the gage post, as it is tilted to engage the part, relative to a predetermined standard
