Abstract: A platform type weighing scale including a base and a scale platform and first and second pairs of platform suspensions for mounting the platform on the base at the four corners of a generally rectangular pattern, an elongated load sensing beam supported at spaced points therealong on the base, and first and second transfer means respectively interconnecting the first and second pairs of platform suspensions to the beam at a common point intermediate the spaced beam suspension points to apply a bending load to the beam correlative with the sum of the loads applied to the first and second pairs of platform suspensions, and electrical strain gauge means mounted on the load sensing beam for producing an electrical signal correlative with the bending stress produced in the beam as an indication of the total weight applied to the scale platform.

Abstract: A platform type weighing scale including a base, a scale platform, and a unitary weigh frame having spaced parallel torque members and an elongated bendable load sensing beam extending between and ridgidly attached to the torque members. Four frame suspensions engage the torque members to support the weigh frame on the base and four platform suspensions engage the torque members to support the platform on the weigh frame and apply forces to the first and second torque members correlative with the load on the platform and to produce a bending moment in the beam correlative with the sum of the forces applied to the first and second torque members. Electrical transducer means senses bending of the sensing beam as an indication of the weight applied to the scale platform.
