Abstract

An elastic-type clamp is used for securing weighing scale flexure plates to a load support. The elastic-type clamp eliminates uncontrolled and unpredictable deflection characteristics of the plates, which were the result of changing boundary conditions and manufacturing differences in the bite of the previously used inelastic clamp. The lips of the inventive clamp are made deformable under load, or as strain develops in the flexure plates. The ability of the clamp to elastically deform prevents slippage of the flexure plates about their point of securement to the load support. This in turn will reduce load measurement errors inherent with the previous inelastic clamping design.
