ABSTRACT:
A combination door handle and security locking system in which the conventional door latch is actuated by turning the five-sided head of an operating shaft with a special socket wrench. A hinge plate having a slot for a padlock bail and a flat index tab on its inner surface is rotated to cover the operating shaft head. The tab must fit against one side of the operating shaft head to allow the hinge plate to be fully closed so that a padlock can be inserted in the bail. The latching mechanism is designed so that this tab will fit against one side of the operating head when the door is fully latched, to thus prevent rotation of the latching mechanism. The free end of the hinge plate has an offset portion which serves both as a sleet hood for the padlock and as a handle for opening the door.
