Patent ID: 7415866

Claim:
A device for determining the center of gravity of an object, comprising: a base platform; a weighing scale platform disposed atop the base platform; a balance beam fulcrum disposed atop the weighing scale platform; an elongate balance beam disposed upon the fulcrum, the balance beam including a scale engagement arm extending from the fulcrum, the scale engagement arm having a distal scale engagement end, and an object attachment arm extending from the fulcrum opposite the scale engagement arm, the object attachment arm having a distal object attachment end; a double action weighing scale disposed atop the weighing scale platform; a weighing pan disposed atop the scale, the pan having an upper surface and a lower surface opposite the upper surface, the scale engagement end of the scale engagement arm of the balance beam being disposed between the scale and the pan, the scale engagement end of the scale engagement arm selectively engaging the lower surface of the pan; a gauging block attachment bracket affixed to the object attachment end of said balance beam, the bracket having first and second mutually orthogonally opposed edges; a gauging block pivotally extending from said gauging block attachment bracket, the block having laterally opposed, first and second stop flanges extending therefrom, the flanges selectively engaging the edges of the gauging block attachment bracket; and an alignment index adjustably orthogonal to the first and second stop flanges; whereby the weighing scale registers the weight of an object placed upon the upper surface of the weighing pan and registers the upward force produced by an object disposed at the object attachment end of the balance beam.
