Abstract
A device for automatically controlling the opening and closing of hoppers of wagons equipped with one or more sets of at least two sealing systems each comprising a master hatch and a supported trapdoor, the edge of the latter being covered with such way by that of the master hatch in the closed position that is kept closed to the supported hatch, characterized in that articulated linkages join respectively the trapdoors of the group of the master hatches and that of the group of the supported hatches, so that the hatches of each of the groups pivot integrally, each set of sealing systems comprising two attraction organs that each request separately and permanently in the direction of closure to a group of trapdoors but being the master hatch of one of the shutter systems equipped with a catch arranged so as to automatically pick up a retention member n corresponding provided in the hatch supported adjacent to the other shutter system when the hatches reach the open position, being kept in this position and releasing this retention member under the action of a cam or ramp attached to the ground and arranged on the path of a probe integral with the retainer, which also has a stop piece that protrudes in such a way that it is applied to a fixed stop integral with the frame of the wagon when said cam or ramp acts on the retainer, but is hidden leaving in freedom the master trapdoor when the cam or ramp ceases in its action on the latter.
