Clamping device for a coil spring of a weighing scale

摘要

A clamping or calibrator device for a coil spring of a weighing scale is described. The clamping device features a block and a pair of shims that sandwich a coil of the spring in a fixed location in the block. A first shim of the pair is contiguously disposed to an inner arcuate surface of the coil. A second shim of the pair is contiguously disposed to an outer arcuate surface of the coil. Each shim conforms to the respective arcuate surfaces of the coil. Each shim comprises a pair of lips that prevent transverse movement of the shims with respect to the block. This prevented movement insures that the coil will be properly located and fixed in position with respect to the block.
