ABSTRACT:
The center locator tool has a flat, rectangular case with a top wall, a bottom wall, and two opposing side walls. The interior of the case houses a spur gear rotatably mounted on a center post extending through the center of the case, the center post having a bore defined axially therein. A pair of arms are mounted so that the arms are slidable through the case on opposite sides of the spur gear, each arm having a rack defined in its edge which engages the spur gear so that when one arm is extended from the case, the other arm is extended an equal distance in the opposite direction. Each arm has a groove defined in its bottom surface for engaging a guide projecting from the bottom wall of the case. The end of each arm has a work engaging plate forming a "V" shape, the opening of the "V" facing towards the center of the tool, the plates depending from the ends of the arms and being adapted for engaging a square or circular workpiece. When the "V" plates engage the diagonally opposing corners of a square or opposite sides of a circle, the center of the surface lies below the bore defined in the center post. An alternative embodiment of the tool has a wheel with an O-ring about its circumference frictionally engaging slots defined in the edges of the arms in place of the spur gear and rack mechanism.
