ABSTRACT:
One double acting cylinder is attached to the doors of a gate assembly via a linkage. A lock out system cooperates with the linkage whereby different parts of the linkage may be immobilized prior to the beginning of a work cycle. The work performed by the double acting cylinder thus passes through the free parts of the linkage to actuate one door or the other.
