Scale system

Abstract

A scale system including a vertically displaceable crown supported by a longitudinally displaceable center section. A sensing means disposed above-ground is actuated by the center section in response to a weight applied to the crown. The sensing means sends a signal to an interpreting means. Inclined, mating surfaces interconnect the crown and the center section so that the crown is displaceable substantially vertically only and the center section is displaceable substantially longitudinally only. Alternative embodiments of the invention include a friction-reducing material for the inclined surfaces to render the coefficient of friction therebetween substantially a constant; a sealing means for the inclined surfaces to prevent deterioration thereof; restraining means for the center section to impede the displacement of the center section and prevent overload of the sensing means; and a locking means to prevent removal of the crown from the center section.
