<p>INVENTION: HYDRANT SECURING DEVICE INVENTOR: MARC CAMPBELL A hydrant securing device is adapted for use on a conventional fire hydrant having an exposed upper valve nut and a pair of caps each formed with a cap nut. The device preferrably comprises a one-piece steel yoke having a generally U-shaped configuration dimensioned for seating directly on the valve and cap nuts. The yoke has a generally horizontal base formed with an opening dimensioned for location about the valve nut, and a pair of downwardly-directed arms, each arm having an opening dimensioned for location about one of the cap nuts. The openings conform generally to the shape of the nuts and prevent rotation of the nuts relative to the yoke so that the caps cannot be removed and water flow cannot be initiated. The yoke is sufficiently resilient that the arm portions can be elastically separated to permit simultaneous location of the openings about the valve and cap nuts and to permit removal of the hydrant securing device in the event of a fire. Each arm has a strap guide formed by displacing a portion of metal from the associated arm to define a passage between the metal portion and the associated arm. A steel strap clamp is extended through the strap guide passages and crimped to prevent separation of the yoke arms and removal of the device. The strap clamp is snapped with a wrench or other prying tool when access to the hydrant is required.</p> |
