ABSTRACT:
A locking device of the type having a lock cylinder containing a lock plug with a threaded rod connected thereto in a manner causing rotation of the rod with rotation of the lock plug by a key operating the tumbler includes a relatively massive cylindrical lock housing having a bore extending axially therethrough, the lock cylinder being fastened against rotational and axial movements relative to the lock housing, and a relatively massive cylindrical sleeve member with a blind bore therein and a screw threaded surface arrangement in a portion of the blind bore for threadingly engaging the threaded rod. In accordance with a first embodiment, relative rotation between the lock housing and the sleeve member is prevented by a counterbore in an open end of the blind bore of the sleeve member of non-circular transverse cross section and a portion of the exterior of the lock housing of reduced circumference, non-circular transverse cross section that is at least partially receivable in the counterbore. In accordance with a second embodiment, such relative rotation between the lock housing and the sleeve member is effectuated by a pair of pivotally connected semi-annular shackle members, the sleeve and lock housing being tangentially secured to a free end of a respective one of each of the semi-annular members. A cover cap assembly is provided which weatherproofs the lock cylinder and may serve to protect and camouflage a fastening screw for the lock cylinder.
