Abstract
Synchronized hopper gate mechanisms (17) are provided for the hoppers (18) of a bulk cargo vessel (11). Each gate mechanism includes a pair of horizontal closure panels (31, 32) and control means for simultaneously displacing the panels in opposite directions. The control means includes a pair of endless chain means (79, 81), cooperating sprockets (82, 83, 84, 86) and a torque transmitting means in the form of a shaft (101) interconnecting sprockets (83, 86) which forces the corresponding runs of the chain means (79, 81) to move in the same direction at the same speed to effect synchronized translational movement of the closure panels (31, 32).
