Abstract
A platform weighing scale having a transducer with a movable element to translate weight responsive platform motion into a weight responsive electrical signal and in which the platform is movably supported relative a scale base by one or more pulley and tape motion linkages which also actuate the transducer element. The improved pulley and tape motion linkage comprising a pulley-like element having diametrically opposite peripheral circular sectors, a tape contacting the circular sectors and connected between the platform and base, a pair of restraining elements sandwiching the pulley-like element for a composite rotary and linear motion between parallel surfaces with the circular sectors contacting the parallel surfaces, an arm fixedly coupled to the pulley-like element at its center of rotation by which a remote segment of the arm follows an amplified composite linear and rotary motion, a second pulley-like element fixed to the remote segment of the arm and having a peripheral circular sector having the same center of rotation as the first pulley-like element, and a second tape contacting the second circular sector and connected between the arm and the movable element of the transducer.
