Abstract:
A method and apparatus for reducing the torque of a compound balance in order to substantially cancel out the torsional force of the torsion spring acting on the spiral rod by creating an equal and opposing torsional force on the extension spring. The apparatus is an assembly connector that is non-permanently engaged with the extension spring, with the spiral rod being tensioned by the torsional force of the torsion spring. Alternatively, the extension spring may be turned in a direction to apply more torque than is required for operation of the compound balance. It is then engaged with a non pre-tensioned spiral rod sub-assembly to transfer the excess torque to the torsion spring of the spiral rod sub-assembly. In this manner, the opposing torsional forces of the torsion spring and the extension spring acting on the spiral rod substantially cancel out each other.
