ABSTRACT:
A locking device includes a threaded stud with a flat face cut through the threaded surface parallel to the axial direction of the stud, and a knob which locks over a forward section of the stud and includes a casing having an inner surface which defines a hole extending axially through the casing. The inner surface of the casing has a flat surface extending axially which receives the corresponding flat face on the threaded stud to prevent rotation of the casing with respect to the stud. The knob also includes a tumbler housing which is mounted in an axially-fixed position within the casing to rotate freely when a key is inserted into the tumbler housing, and to remain locked in a fixed position when the key is withdrawn. Fitted into the rearward end of the tumbler housing is a sleeve having a threaded axial hole which engages the threaded stud when the tumbler housing is turned by a key to thereby pull the forward section of the stud into the casing hole.
