Fire hydrant locking device
First Claim
1. A locking device for a fire hydrant, the fire hydrant including an upright generally cylindrical barrel having a mounting flange at its upper end, a domed bonnet having a mounting flange fastened to the mounting flange of the barrel, and an operating nut protruding through the bonnet for operating a valve in the fire hydrant to permit water to charge the hydrant, comprising:
- a cap for placement over the protruding portion of the operating nut and enclosing the operating nut;
at least one arm connected at one of its ends to said cap, said arm being sized and shaped to extend from said cap, when placed over the operating nut, downwardly and about the dome of the hydrant toward the barrel and passing downwardly beyond the mounting flange of the barrel;
bracket means sized and shaped to removably receive said arm, said bracket means being adapted to be fastened to the mounting flange of the barrel, wherein a longitudinal passage is defined within said bracket means and passes therethrough, said passage being adapted to receive said arm therein;
a generally horizontal tamper shield disposed on said arm, said tamper shield being sized and shaped to be received on said bracket means; and
means for locking said arm to said bracket means so that said cap, said bracket means, and the bonnet of the fire hydrant cannot be removed from the fire hydrant when said locking means is locked.

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.

11. A locking device for a fire hydrant, the fire hydrant having an upright generally cylindrical barrel, a mounting flange at the upper end of the barrel, a domed bonnet having a mounting flange fastened to the mounting flange of the barrel, and an operating nut protruding through the bonnet for operating a valve in the fire hydrant to permit water to charge the hydrant, comprising:
-
a cap for placement over a protruding portion of the operating nut and enclosing the operating nut; an integral arm and bracket assembly, wherein an arm portion of said assembly is connected at one of its ends to a bracket portion of said assembly, the free end of said arm having a lock hole defined therein and passing therethrough adapted for receiving a lock, wherein said bracket portion of said assembly comprises a rigid U-shaped bracket having two parallel legs spaced apart from each other a distance greater than the breadth of the fire hydrant barrel, and a distance less than the breadth of the barrel mounting flange; a pair of openings defined within said cap sized and shaped to receive the free end of said arm, said openings being disposed along a common horizontal axis and being adapted for receiving said arm therethrough; a lock for locking said integral arm portion and bracket assembly to said cap; whereby the free end of said arm is extended through both of said openings within said cap, and said bracket portion is passed over the barrel, below the mounting flange of the barrel, and said lock is placed through said lock hole within the free end of said arm to lock said integral arm and bracket assembly to said cap upon the fire hydrant.
