Stetson's invention "is adapted for railroad-track scales and other heavy scales, were it is important to employ what is generally known as knife-edges to receive the strain, and where the first and second levers require provisions for a lateral, longitudinal, and irregular motion relatively to each other. The invention affords each knife-edge a fair bearing on a long surface, and allows one set to move horizontally in all directions relatively to the others." (Patent Number 167,705)
