Object centering and moving mechanism

摘要

A mechanism is disclosed to raise a round or hexagonal object having a center and to establish the center on a fixed reference line regardless of the diameter of such object within a finite range of diameters. First and second caliper means engage opposite sides of each such object to sense the diameter and to act through a lever linkage with a two-to-one mechanical advantage so that a stop on the linkage coacts with a fixed frame. The calipered diameter of the object establishes the position of the stop means relative to the fixed frame so that the center of the object is on the fixed reference line regardless of the diameter of the object. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all priciples of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
