ABSTRACT:
An improved gate driving link mechanism is provided, this mechanism being originally designed for opening and closing a flapdoor type discharge gate of a weighing hopper of top-charge and bottom discharge type, used in a combination weighing device such as disclosed in U.S. Pat. No. 4,344,492, the improvement of which is to add an intermediate bell crank for confining overshoot of the opened gate to avoid unwanted time loss which affects high speed operation of the device and undesirable shock and vibration which affect accuracy of measurement.
