ABSTRACT:
A platform scale having an interconnected lever type suspension in which all of the suspension links are adjustable for optimum alignment of the mechanism. Each suspension member has an adjustable pin with a V-notch to receive a thin blade type hanger link, each pin having locking means by which the mechanism can be set with all the hanger links accurately vertical, so that no offset loads or drag are applied to the scale. The mechanism is applicable to electronic readout systems utilizing strain gauges or similar force indicating means, or to beam type scale mechanisms with adjustable weights.
