ABSTRACT:
A weighing machine with a digital display and having a lever and coded disc that rotate about a common axis. The disc is constrained to rotate in the direction of the lever after a preset time delay, the lever rotating a distance related to the weight of an object placed on the machine. Indicia on the disc are counted during the time interval between initiation of disc rotation and the striking of a contact on the disc with a contact on the lever, the number of counts defining the weight of the object.
