ABSTRACT:
A locking device includes a base having openings therein for joining the base to a first surface, such as the surface of the door, and a cover hinged to the base plate by a solid bar passing through apertures in flanges near the upper end of the base plate and cover. This solid bar is sufficiently long to engage an opening in a second surface, such as a door jamb. Joined to and extending laterally from the solid bar is a second bar that lies between the flanges of the cover plate, thus confining the second bar to the space between them, and preventing removal of the solid bar from the device. Projecting from the inner surface of the plate and from the inner surface of the cover are lock-receiving flanges having apertures which lie proximate one another when the cover plate is closed against the base. The apertures in these lock-receiving flanges lie at least partly in the same plane, permitting the hasp of a padlock to pass through both, thus locking the cover to the base plate. When the solid bar engages the opening in the second surface, the second bar lies on the side of the lock-receiving flanges nearer the opening. Locking the flanges together prevents disengagement of the solid bar from the opening in this situation.
