Abstract
Abstract A demountable optical tooling scale fixture wherein a tooling ball is demountably attached by a connecting member and plate to a reference point on a surface to be measured and is positioned within and rotatably gripped by two plates set in a face-to-face relationship to each other; said plates are designed to receive optical tooling scales directly or by means of adaptors. In each case, the optical tooling scale will be positioned in a known spatial and angular relationship to the ball which in turn is held at a known distance from the point of mounting on the surface to be measured.

Claim 1
Independent Claim
288 words
A demountable optical tooling scale fixture, comprising: a. a base plate and a cover plate positioned in face-to-face relationship; b. said base plate and said cover plate each having formed on their opposed surfaces a partial ball seat of approximately equal dimensions, the seats being aligned and mutually opposed so as to cooperatively receive a spherical tooling ball; c. connecting means for fastening the plates together; d. a spherical tooling ball positioned in said opposing ball seats and rotatably gripped by the seating surfaces of both ball seats upon engaging said connecting means; e. said base plate having a thickness less than the radius of curvature of the ball seat formed therein, thereby forming an opening through the base plate centrally of said ball seat and communicating therewith; f. mounting means attachable to a surface to be measured, said mounting means including a shank portion extending through said opening in said base plate, and said tooling ball being attached to the distal end of said shank portion, the maximum transverse dimension of the shank adjacent the tooling ball being substantially less than the diameter thereof, and the longitudinal axis of the shank being substantially aligned with a radius of said tooling ball, thereby allowing said plates rotatably gripping said tooling ball to be adjustably rotated through an angle of rotation about said tooling ball surface to place the plates in a predetermined relationship with the surface to be measured, said rotation being limited by the relationship between the size of said opening and the transverse dimension of said shank; and g. means for mounting at least one optical tooling scale on at least one of the plates in a plane parallel to a radius of the tooling ball.
