Abstract: A platform weighing scale includes a base with vertical corner stands and a weight supporting platform including depending corner bearings. A weight sensing apparatus is supported on the base corner stands and supports the weight supporting platform so that it is moveable relative to the base. A weight sensing mechanism is responsive to movement of the platform for operating a weight indicating device. The weight sensing mechanism includes a plate operatively associated with the weight indicating device. A pair of primary levers are secured at one end to the plate and diverge therefrom relative to a longitudinal centerline and define a select angle therebetween. Each primary lever includes an upper notch receiving one of the corner bearings and a lower notch receiving one of the corner stands so that movement of the platform causes pivotal movement of the levers to move the plate.
