Abstract
Abstract A force-measuring system in which the force of a load of material is applied to a load-responsive element to produce a signal proportional to the weight of material. There is a load beam by which the force is applied to the load-responsive element. A counterbalance beam is connected to the load beam to counterbalance at least a part of the static weight that would otherwise be applied to the load responsive element. The forcemeasuring system is compactly constructed, and the elements are highly stabilized to be accurately responsive.

Claim 1
Independent Claim
315 words
A load measuring system including a load-responsive element which provides a signal that is proportional to the magnitude of the load, a load beam bearing on said load-responsive element, means to apply the load to said load beam for transmitting the force of the load to said load-responsive element, a fixed support for said load beam, a first flexure element to connect said load beam to said fixed support in a transverse plane, a second flexure element to connect said load beam to said fixed support in an upright plane, the transverse plane of said first flexure element and the upright plane of said second flexure element are placed in intersecting disposition and establish a pivot position for said load beam at the intersection of said transverse plane with said upright plane to permit the load beam to yield in response to the force of the load, counterbalance means to at least partially counterbalance the load that is applied to said load beam, said counterbalance means comprises a counterbalance beam, means to connect said counterbalance beam to said load beam to oppose movement of the load beam which is produced by the force of the load that is applied to the load beam, said load beam extends laterally from said fixed support, said counterbalance beam extends laterally from the outer end of said load beam and along the load beam in the opposite direction to a position located beyond said fixed support, a counterweight on the counterbalance beam at said position that is beyond said fixed support, a third flexure element for said counterbalance beam that is disposed at an intermediate position between the ends of the counterbalance beam to yieldably support the latter, a fourth flexure element connecting the outer end of said load beam to the adjacent end of said counterbalance beam at a position that is spaced from said third flexure element.

Claim 3
Dependent Claim
267 words
A load-measuring system including a load-responsive element which provides a signal that is proportional to the magnitude of the load, an upright post at one side of the load-responsive element, a load beam extending laterally from said upright post to a position at the opposite side of said load-responsive element, said load beam bearing on said load-responsive element, a first leaf spring flexure element to connect said load beam to said upright post in a transverse plane, a second leaf spring flexure element to connect said load beam to said upright post in an upright plane, the transverse plane of said first flexure element and the upright plane of said second flexure element are placed in intersecting disposition and establish a pivot position for said load beam at the intersection of said transverse plane with said upright plane to permit the load beam to yield in response to the force of the load, a counterbalance beam disposed at opposite sides of said load beam and extending laterally along the load beam to a position beyond said upright post, a counterweight on said counterbalance beam at said position beyond said upright post, a fixed support for said counterbalance beam, a third leaf spring flexure element to connect said counterbalance beam to the last said fixed support to yieldably support the counterbalance beam on its fixed support, a fourth leaf spring flexure element to connect said load beam and said counterbalance beam to oppose movement of said load beam by the counterbalance beam which acts in the opposite direction from said load beam under the force of said counterweight.
