Abstract
Abstract A key operable padlock having a padlock body provided with sockets for the legs of a U-shaped shackle, and a central bore located between the sockets shaped to receive and removably house a key lock plug. The bottom wall of the padlock body has a key opening which projects into the key lock plug to operate the plug, and the upper portion of the padlock body has an elongated slot defining a slideway and the cover member is removably positioned. The sides of the slideway and the cover member have alternating tongue and groove formations which interfit with each other to permit the cover member to slide into covering relation over the central bore and through the region of one of the shackle legs to the adjacent end of the padlock body, and the cover member has a cylindrical opening which registers with the socket for one of the shackle legs to receive that shackle leg when the cover member is fully seated in the slideway. Interlocking means are provided to prevent removal of the cover member unless the key lock plug is operated in a special manner.
