Patent number: 11167161Abstract: The hydrant monitoring system determines whether water is present in a dry-barrel fire hydrant. The hydrant monitoring system couples to a port of the hydrant using a hydrant port adapter. The hydrant monitoring system supports an operator interface unit mounted within a protective frame next to the hydrant on a fixed arm. A movable arm carries a distance sensor aimed downward that slides into and out of the hydrant on the fixed arm. The hydrant monitoring system is used by making a first distance measurement outside of the hydrant, making a second distance measurement inside of the hydrant, and subtracting the two to determine how far below ground level the bottom of the barrel is. If the bottom is not at a predetermined depth, a request to drain or service the hydrant may be initiated.Type: GrantFiled: July 10, 2018Date of Patent: November 9, 2021Inventor: Senthuran Pon Suntharalingam

Patent number: 7140212Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.Type: GrantFiled: June 14, 2005Date of Patent: November 28, 2006Assignee: The Knox CompanyInventor: Dohn J. Trempala

Patent number: 6948512Abstract: A device and method for automatically flushing hydrants. The device is installed externally to an existing hydrant. The device comprises a nipple having an internally threaded collar for attaching the device to a hydrant outlet, a valve, a control for automatically operating the valve, and a lockable box containing at least the valve, the box having an outlet for allowing water from the hydrant to pass from the valve to the exterior of the box. The box functions as an enclosure and may be of any desired configuration.Type: GrantFiled: November 19, 2004Date of Patent: September 27, 2005Assignee: John C. Kupferle Foundry Co.Inventor: Daniel G. McKeague

Patent number: 6816072Abstract: A detection and signaling apparatus is mountable in a fire hydrant to detect a parameter, such as unauthorized movement of a discharge nozzle cap relative to the fire hydrant. A housing carrying a sensor, such as a motion detector, is mounted inside of the cap. The sensor has an output connected to a transmitter. Movement of the cap relative to the fire hydrant activates the motion detector which generates an output signal causing the transmitter to remotely transmit a tamper detection signal and, also, a fire hydrant location identification code. A pressure sensor can also be coupled to the transmitter to sense water supply main pressure and water flow through the fire hydrant.Type: GrantFiled: December 5, 2002Date of Patent: November 9, 2004Inventor: Michael Zoratti

Patent number: 6802338Abstract: A fire hydrant securing arrangement utilizes a magnetic detent to couple an outer body to a center post so that when a wrench with a permanent magnet is mated with the outer body, the magnetic detent connects the outer body to the center post. The center post has an end with a polygonal recess which complements the shape of the hydrant operating nut. The recess is within an insert that has a polygonal periphery engaged by a polygonal inner wall of the center post. The insert is interchangeable with other inserts having recesses of different sizes and configurations so that the securing arrangement is readily acceptable to fire hydrants having different operating nuts of different sizes.Type: GrantFiled: October 14, 2003Date of Patent: October 12, 2004Assignee: Hydra-Shield Manufacturing, Inc.Inventor: Roy Istre, Jr.
