ABSTRACT:
A twin leaf spring weighing scale, wherein the leaf springs are connected to each other in tandem about a common support. One of the leaf springs is angled above a horizontal axis, so as to deflect downwardly with an increasing effective bending length. The other leaf spring is positioned along a horizontal axis to provide a decreasing effective bending length as it deflects downwardly. The two leaf springs act together to provide a unitized leaf spring structure that has a constant spring rate throughout the weighing range of the scale.
