ABSTRACT:
The fire hydrant locking device has a cap (20) enclosing the operating nut (12) of the fire hydrant (6). The cap is secured in place on the top surface of the fire hydrant bonnet (10) by at least one arm (22) extending downwardly over and about the bonnet and extending beyond the fire hydrant barrel mounting flange (9). The lower end of the arm (22) is attached to the flanges (9 and 10') of the barrel (8) and bonnet (10) by bracket (26) and its pad lock (25) so that the cap, arm, and bonnet of the fire hydrant cannot be removed without first removing the fire hydrant locking device. Another locking bracket (80) is received on the outlet cap (17), of the fire hydrant hose outlets (16). Chain (86) is passed through each locking bracket encircling the fire hydrant, whereupon the ends of the chain are pad locked together.
