Apparatus for contour measurement of a member

Abstract

Abstract THIS INVENTION RELATES TO APPARATUS FOR CONTINUOUSLY DETERMINING A DIMENSION OF A MEMBER, THE APPARATUS HAVING A FRAME DISPOSED ADJACENT THE PATH OF MOVEMENT OF THE MEMBER, A CARRIAGE RECIPROCABLE ON THE FRAME TOWARD AND AWAY FROM THE MEMBER, DRIVE MEANS CONNECTED TO THE CARRIAGE AND A SENSING ASSEMBLY ON THE CARRIAGE FOR CONTINUOUSLY MEASURING THE DIMENSION. THE SENSING ASSEMBLY HAS A MOVABLE MEMBER RECIPROCABLE ON THE CARRIAGE TOWARD AND AWAY FROM THE DIMENSION, SENSING ASSEMBLY DRIVE MEANS CONNECTED TO THE MOVABLE MEMBER, A FIRST SCANNING MEMBER AND A SECOND SCANNING MEMBER PIVOTED ON THE MOVABLE MEMBER, A FIRST PROBE ON THE FIRST SCANNING MEMBER, AND A SECOND PROBE ON THE SECOND SCANNING MEMBER AND BIASING MEANS CONNECTED TO THE FIRST SCANNING MEMBER AND TO THE SECOND SCANNING MEMBER FOR BIASING THE FIRST PROBE TOWARD THE SECOND PROBE. A PROXIMITY MEMBER IS ON THE CARRIAGE FOR DETECTING THE MEMBER AND IS CONNECTED TO THE DRIVE MEANS AND THE SENSING ASSEMBLY DRIVE MEANS. THE PROXIMTY MEMBER IS OPERABLE WHEN IT ENGAGES THE MEMBER TO STOP THE DRIVE MEANS AND MOVEMENT OF THE CARRIAGE TOWARD THE MEMBER AND TO START THE SENSING ASSEMBLY DRIVE MEANS THEREBY CAUSING THE SENSING ASSEMBLY TO MOVE FROM AN INITIAL POSITION TOWARD THE DIMENSION SO THAT THE FIRST PROBE AND THE SECOND PROBE ENGAGE THE MEMBER AND CONTINUOUSLY MEASURE THE DIMENSION DURING MOVEMENT OF THE SENSING ASSEMBLY TOWARD THE MEMBER.
