Claim:
A dust and particulate containment system for a gallery conveyor having at least one open side and a conveyor belt thereon for transferring bulk materials therein, the system comprising: a movable curtain for covering the at least one open side of the gallery conveyor; a trough positioned within the gallery conveyor and extending along a length of the conveyor; a rail positioned within the gallery conveyor, and extending alongside a length of the trough; a carriage adapted for movement along the rail and having an opening for transferring bulk materials therethrough; a seal adapted to retain the curtain in place and seal a portion of the trough; and a spreader frame attached to the carriage, the spreader frame being adapted to biasingly open the seal and free the curtain from retention with the seal when brought into contact therewith, whereby, through movement of the carriage along the rail, the curtain is lifted over the carriage and avoids covering of the opening in the carriage.
