  • Patent number: 8991415
    Abstract: A fire hydrant break off valve includes an offset pivot and a lateral trigger captured between a fire hydrant and fire hydrant break off riser. When a collision breaks the break off bolts holding the fire hydrant to the hydrant break off riser, the lateral trigger is released and the valve rotates to a closed position. Force of water attempting to escape rotates the valve around the offset pivot. The edge of the valve is tapered and after rotating, the valve is pushed against a matching seat to close the valve. The match of the tapered valve against the tapered seat stops or nearly stops all flow of water from the broken hydrant.

As constructed in an open hole, the hydrant installation includes a hydrant riser that is positively joined to a water main and a valve casing that merely sits with a gravity fit on a hydrant valve located between the main and riser. For use, the lower bracket spacer is placed in an adjustable state allowing its respective clamps to be attached to respective lower ends of the riser and casing. Then, the lower bracket spacer is secured in place. Next, the upper bracket is attached in a like manner to respective upper ends of the riser and casing.

  • Patent number: 5622202
    Abstract: A tamper proof fire hydrant which may only be operated by the application of pressurized fluid. The pressurized fluid engages the fire hydrant and travels through a pathway in the upper portion of the fire hydrant. The pressurized fluid engages a turbinelike impeller and then the pressurized fluid pressure rotates the impeller, the impeller is connected to a worm gear and turns the worm gear which then operates to open the hydrant's water main valve. Later the flow of fluid is then reversed in order to turn the turbinelike impeller in the opposite direction thereby causing the worm gear to operate to close the hydrant's water main valve. A cylinder and piston may be used in place if the impeller and worm gear, to open and close a water main valve in response to the application of pressurized fluid to the fire hydrant from an external source.

  • Patent number: 5404899
    Abstract: A single piece hat-shaped catchment device for preventing machine parts and tools from falling into the inaccessible interior of a mechanism during the servicing thereof. The catchment device includes an inner section defining a central hole and a plurality of radially disposed segments, and an outer section defining a stop for limiting the depth to which said inner section can penetrate into the interior of said mechanism. During servicing the device is pushed downwardly over the exposed part of the mechanism to form an annularly disposed catchment trough for machine parts and tools. After servicing has been completed and any dropped parts or tools have been removed from said trough, the device is quickly and easily pulled upwardly off of said exposed part to permit the mechanism to resume normal operation.

  • Patent number: 5287880
    Abstract: A three-way wet barrel fire hydrant includes an enlarged intermediate barrel section, which effectively reduces pressure loss in the fire hydrant. The hydrant barrel is formed by an improved sand molding process which requires the mold parting line of the barrel to be selected to coincide with the centerline of the upper nozzle opening. In this manner, a pattern which forms the sand mold may be removed cleanly from the molding sand, thereby eliminating the need of multiple side cores during the casting process.

  • Patent number: 5201338
    Abstract: A water distribution system includes flushing hydrants having buried valve assemblies and a removable top stock carried from valve assembly to valve assembly. A vertical marker replaces the top stock when the hydrant is not in use. The buried valve assembly includes a valve urged closed by water pressure and an actuator rod extending through a spider in the top of a vertical barrel. A lock nut on the upper end of the actuator holds the valve closed even if water pressure is lost. The upper end of the vertical barrel includes an internally threaded adapter. The top stock includes a casing which is externally threaded to mate with the adapter and a second rod which is threaded to mate with the actuator rod. The hydrant is assembled by removing the lock nut and screwing the parts together while an operating screw is swung free, then swinging the operating screw into engagement with the second rod. A preferred embodiment permits water samples to be taken from the hydrant.

  • Patent number: 5082013
    Abstract: A system consisting of multiple independent units each of which includes two standard fire hydrant connections located on two riser pipes and an interconnecting underground pipe providing a means for drafting tide, lake or river water from a streetside conneciton. Any pumper/tanker truck can thus connect a suction hose to the streetside riser and draft water through a second suction hose with one end connected to the riser at a bulkheaded waterside location and the other end equipped with a strainer is lowered into the water source. Standard lengths of fire hose suffice at both water and streetside connections when the water is bulkheaded and water level variations are sufficiently small that the lift capability of the pump is not exceeded. Pumping many begin when connections are complete. Backflushing with fresh water carried on the pumper/tanker may be performed if the pump is not well sealed and pumping begins after backflushing is complete and flow direction is reversed.

  • Patent number: 4805862
    Abstract: A harness is provided for supporting a water meter on a fire hydrant so as to minimize the possibility of the water meter being accidentally dislodged from the first hydrant. The harness comprises a first loop which fits around the conical top of the fire hydrant and a second loop which fits around a portion of the water meter. A rod extends between the two loops and tensioning means is provided to draw the two loops toward one another via advancing the rod so as to both pull the water meter back toward the fire hydrant and to suspend that end of the water meter to which a water hose is attached from the conical top of the fire hydrant.
