Weight scale structure

Claim 1

In combination, a substantially unfluctuating, substantially non-moving scale structure and a driven conveyor and platform having a receiving end and a delivery end for measuring imposed weight load on the conveyor in terms of a known proportional part of the power resulting from the imposed weight load on the conveyor and automatically self-compensating relative to the position and movement of the imposed weight load on said conveyor as it is conveyed from said receiving end of the conveyor to said delivery end of said conveyor comprising; a base having opposite ends and a central area, a weight sensitive device on said base spaced from said central area, a first fulcrum near said one end of said base, a second fulcrum near said other said end of said base, a first beam above said base having an outer end pivoted on said first fulcrum, a second beam above said base having an outer end pivoted on said second fulcrum; both said beams having inner ends adjacent one another; each said beam having a weight bearing point intermediate its said inner end and its said outer end; a conveyor and platform lying above both said beams, and legs supporting said platform resting on said bearing points of both said beams; weight load imposed on said conveyor and platform at random being divided into separate ambient portions by said legs at said bearing points on said beams; each said beam proportionally dividing the ambient weight load portion imposed on each said beam between its said fulcrum end and its said inner end; said first beam at its said inner end bearing on the said inner end of said second beam cumulating their exerted power, and a lever arm extension having opposite lever ends with one said lever end solidly connected at one of its said lever ends to said second beam at said second beam''s inner end and with said other lever end extending thErefrom; said weight sensitive device lying under said other projecting lever end of said lever arm; said projecting lever end of said lever arm bearing on said weight sensitive device as an integral extension of said second beam; said lever arm thereby diminishing the load imposed on said weight sensitive device to reduce deflecting motion and resulting fatigue, to increase accuracy of measurement, and to increase life span of said weight sensitive device; the cumulation of the proportional ambient weight load portion imposed on each said beam inner ends being an accurate proportion of the total weight load imposed on said conveyor and platform which is transmitted to said beam inner ends and in turn transmitted to said weight sensitive device via said lever arm extension as a true proportion of the total weight load on said conveyor and platform with said random division and proportional cumulation compensating for weight load position and movement on said conveyor platform causing the imposition of more weight on one beam than the other at any one time.
