Abstract: The base of a weigh scale includes openings in the bottom thereof at each corner. The base is raised above a supporting surface by way of rigid foot members aligned with the openings in the corners of the base. Load cells in the form of deflection beams each having one of their ends fixed to the base while their other end contacts upper surfaces of their respective foot members. Damage to the load cells by side shock loads is eliminated by way of resilient coupling members connected between the foot members and the base.

Abstract: Theload cell herein disclosed is designed for precise measurement of forces along or parallel to a single axis, while being substantially immune to forces applied along the other mutually perpendicular axes as well as moments applied about any of the three mutually perpendicular axes. Rigid force input and force output members are resiliently interconnected by a pair of parallel flexure beams which establish with such members a parallelogram type of linkage which is relatively yieldable to forces parallel to the selected measurement axis while being relatively stiff and unyieldable to forces parallel to the other two axes and to moments about any of the three axes. A strain gage-equipped sensing beam is mounted within the plane of the parallelogram linkage and between the two flexure beams. One end of the sensing beam is rigidly connected to the fixed force output member, while the other end is free to flex in cantilevered fashion responsive to displacement of the force input member. The sensing beam thereby provides part of the resilient interconnection between the force input and force output members, and is dimensioned so that its stiffness relative to that of the two flexure beams causes it to absorb 80 to 90% of the applied loads. Adjustable overload protection means are provided, which cause excessive forces to be safely by-passed around the resilient members and the strain gages.
Abstract translation: 本文公开的负载单元被设计用于精确测量沿着或平行于单个轴线的力，同时基本上不受沿其它相互垂直的轴施加的力以及施加在三个相互垂直轴线上的任何一个的力矩。 刚性力输入和力输出构件通过一对平行弯曲梁弹性地互连，所述平行弯曲梁与这些构件形成平行四边形类型的连杆，该平行四边形类型的连杆相对于平行于所选择的测量轴线的力相对屈服，同时相对刚性并且不能平行于 其他两个轴和任何三个轴的力矩。 应变计装备的传感梁安装在平行四边形连杆的平面内和两个弯曲梁之间。 感测梁的一端刚性地连接到固定力输出构件，而另一端响应于力输入构件的位移而以悬臂方式自由地弯曲。 因此，感测梁提供了力输入和力输出构件之间的弹性互连的一部分，并且其尺寸使得其相对于两个弯曲梁的刚度使其吸收施加的负载的80％至90％。 提供了可调节的过载保护装置，这些过载保护装置使得过大的力被安全地绕过弹性构件和应变计。

Abstract: A flexure-based transducer especially adapted for very precise measurement of small forces in either direction along or parallel to a single axis, without being adversely affected by forces applied in any other direction or by moments applied about any axis. The transducer is capable of withstanding very high overloading, without damage, by the provision of two resilient portions mounted in parallel to each other but in series between the gaged portion and a fixed support, plus an overload pin on the gaged portion which bottoms after a pre-determined travel.
