Abstract: A load cell of the beam type having a planar operator member having a pair of parallel longitudinal slots defining a central beam member and a pair of parallel bearing members spaced outwardly of the beam member, the outer ends of the bearing members and of the beam member being integral with one another, the operator member having a pair of laterally outwardly extending support members positionable on a horizontal laterally spaced surface of a support block, the load or force to be measured being applied to the central portion of the beam member which is provided with strain measuring means such as strain gages at locations of flexure of the beam member. The support block may have a pair of transversely extending narrow edges underlying the central portions of the bearing members for preventing torsional movement of the bearing members as the load is applied to the beam member. A modified form of the load cell has an operator member whose support members extend parallel to and longitudinally of the bearing members and are secured thereto by transverse connector members, the support members being secured at opposite ends to horizontal support surfaces of a support block, the connector members and the bearing members engaging transverse narrow edges of the support block whereby the support members may be prestresssed upwardly at their midpoints.
