Title: Load cell scale

Abstract: An improved load cell scale which comprises a load supporting frame pivotally carried upon levers which bear upon a load cell on the frame and, are in turn, pivoted upon fulcrum pins. All pivot pins are journaled in oversized bores formed in the levers so as to rock the pins with a slight rolling motion in the bores under load-induced pivotal action, rather than with rotation about the pin axis.
