Abstract:
A dust control device for preventing dust and debris from escaping into the atmosphere during the process of loading rail cars with grain or other granular commodities/products. The dust control device generally includes a dust hood that is moveably supported on a pair of stationary elongated support rails via wheels. The support rails are attached to a delivery spout of an elevator and extend over the path of travel of a rail car to be loaded. An elongated pivotable engagement arm connected to the dust hood extends downwardly into the path of the rail car and is engaged as the car passes beneath the dust hood. The dust hood moves with the rail car from a ready position to an operational position in close proximity to the delivery spout to capture the dust and debris generated during the loading process. When the rail car disengages from the engagement arm, the dust hood returns to the ready position automatically and without a power source under the force exerted by a spring-biased positioning assembly.

Claim (Index 13):
A dust control device for use with a facility having a delivery spout for delivering a commodity to a moveable vehicle, comprising:\n a pair of elongated support rails, wherein each support rail has a proximal end, wherein the pair of support rails extends longitudinally over a path of travel that approaches and passes under the delivery spout, and wherein the proximal ends are adapted to be connected to the delivery spout; a first stop connected to the pair of support rails at a first position longitudinally spaced from the delivery spout; a second stop connected to the pair of support rails at a second position in proximity to the delivery spout; a hood having a bottom opening adapted to capture dust, a top opening adapted to be connected to a remote dust containment apparatus of the facility, and a plurality of rotatable wheels, wherein the hood is moveably supported by the wheels on the support rails with the bottom opening substantially facing the path of travel, and wherein the hood is reciprocally moveable on the support rails between the first stop and the second stop; an elongated engagement arm connected to the hood and extending generally downward into the path of travel, wherein the arm is adapted to be engaged by a moveable vehicle traversing the path of travel; a positioning assembly connected to the dust hood and operative without a power source to automatically cause the dust hood to move to the first position when a vehicle is not in engagement with the engagement arm; and wherein the hood is adapted to move on the support rails to the second position when a vehicle traverses the path of travel into proximity with the delivery spout while in engagement with the engagement arm.
