9 6% of the Passenger Vehicles exhibited with Destination Indicators at the Commercial Motor Show were equipped with " ECO " Patent Spiral Gearing.
" ECO " Patent Spiral Gearing for Destination Indicators is the finest Gearing Mechanism yet designed for the easy operation of Indicator Screens. It is the only gearing which will not shift due to vibration:there is no clutch of any sort for reversing the direction of movement of the rollers and it will not jam or tear the blind.
