ABSTRACT:
A lockable closure plug consisting of a top-flanged cylindrical resilient compressible body with a top plate covering the top of the body and a flat bottom plate engaging the bottom of the body, and an axial operating stem rotatably engaging centrally through the body and abutting on the top plate and threadedly engaged through a nut secured centrally to the bottom plate. A rod-like handle bar is secured perpendicularly through the top end of the stem and a pair of link bars are pivoted to opposite sides of an upstanding U-shaped bracket on the top plate. The link bars in raised positions can lockingly receive the handle bar therebetween, and said link bars are apertured to receive the hasp of a padlock, which can hold the link bars in raised locking positions. The link bars have end stop lug portions near their pivot points, the lug portions being engagable with the top plate to prevent the link bars from being rotated outwardly away from the handle bar, thus preventing the handle bar from being unlocked unless the padlock is removed. Without the padlock, the link bars can assume normal lowered positions on opposite sides of the stem below the level of the handle bar, allowing the stem to be rotated.
