This application is a continuation-in-part of co-pending application Ser. No. 671,187, now abandoned, filed July 11, 1957, by the applicant. Abstract: The invention disclosed herein relates generally to precision measuring instruments, and has particular reference to a novel toolmaker's square wherein minute deviations from an exact right angular relation can be measured with extreme accuracy. In accordance *with the invention, the principal component of the novel square is an upstanding, graduated right cylinder the base of which has been ground off' at a precise oblique angle so that rotation of the cylinder with its base resting upon a trued reference surface will cause the longitudinal surface elements of the cylinder to assume varying degrees of angular deviation from a plane perpendicular to the reference surface and the amount of the deviation at any point during the rotation is directly readable on the cylinder. Claim: A direct reading toolmaker's square comprising a base member having horizontal upper and lower surfaces in parallel relation to one another, and a cylindrical body formed with its upper end perpendicular to the longitudinal axis of the body and its lower end obliquely disposed with respect to said axis, said cylindrical body being rotatably mounted in upright position on said base member adjacent one end thereof with its obliquely disposed lower end abutting against the base member upper surface so that the longitudinal axis of the body generates an inverted conical surface when the body is rotated relative to the base member, said member being of sufficient size and weight to maintain said body in upright position, said body being formed with permanently inscribed circumferential and longitudinal graduation markings on the cylindrical periphery thereof for direct measurement of deviations from an exact right angular relation when said body is rotated in contiguous relation to an upstanding member being tested for perpendicularity with respect to the horizontal surfaces of said base member, said graduation markings permitting a direct reading to be taken on said body when a surface element thereof makes line contact with said upstanding member during rotation of the body.
