when the scale is calibrated to 0 weight and the manner in which this is accomplished has been heretofore described the manner in which the weight of the scale platform and the transport means is transferred to the load cell will now be described with reference to fig2 a mounting base generally indicated by the reference numeral 136 is seen to comprise an elongate frame member 138 having a pair of wings 140 formed at opposite ends of the frame member 138 the wings 140 are supported at their outer ends by a pair of feet 142 each foot 142 having opposed pairs of upper and lower flanges 144 and 146 respectively at the front and rear edges thereof the outer ends of the wings 140 being disposed between the flanges 144 and 146 suitable resilient bushings 148 are captured between adjacent surfaces of the outer ends of the wings and the flanges 148 to secure the feet 142 onto the wings and to provide a resilient support to the scale platform transport assembly and load cell combination to provide for isolation of the weighing platform from vibrations emanating from either the operation of the mail processor itself or from other external equipment the frame member 138 includes a laterally extending platform 150 to which one longitudinal end of a load cell 152 is secured by means of suitable screws not shown extending.
