Vehicle coupling weighing device

Abstract

Abstract An electromechanical weight-measuring system for weighing successive and cumulative loads deposited in a load-receiving medium employs a plurality of elastic deformable elements supporting the receiving medium at a plurality of predetermined load points. The elastic deformable elements are each positioned intermediately of a load point and a related ground-engaging supporting unit and each has affixed thereto an electrical strain gage medium interconnected in a circuit for amplifying and indicating changes in the weight imposed upon the receiving medium. The invention of this divisional application employs, in addition to a plurality of ground-engaging support means interconnected by the elastic elements with the receiving medium, a second ground-engaging supporting unit having an above ground support connection element together with a weight-responsive coupling device interconnecting said last-mentioned support connection element with one of the crucial load points of the receiving medium, said coupling device comprising a substantially horizontal, elastic weight-bendable member having one of its end portions connected to said last-mentioned support connection element and having another end connected and affixed to partially support said receiving medium. One of said connections of said deformable coupling elements is mounted for oscillation on a substantially horizontal axis extending longitudinally thereof. Electrical strain gage means is mounted on said deformable elastic member and is interconnected with the electrical circuitry of the strain gages of said other units to interpose as a factor in measurement of overall load weight that proportion of weight superimposed on said coupling.
