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.
