ABSTRACT:
A device is provided for locating the center position of an object directly, without the need of measurement or mental computation. The device comprises a generally flat elongated frame having a center point marker and distance scales. Two pins are journaled in the frame, and a cord is disposed around the pins to form a taut, endless pulley. Alternately, the pins can be eliminated and the frame slotted to receive the cord. Two end point markers are attached to the cord, one on each run of the pulley circuit. The end point markers abut at the center point marker on the frame. In use, the end point markers are adjusted to match the ends of the object in question. Since the displacement of each end point marker from the center point is equal, the center point marker indicates the center point of the object. Additional features provided are a lock screw to hold the index markers in one position, and a fine tuning adjustment to make fine corrections to the end point marker positions.
