Reciprocating Riser Patents (Class 137/287)
  • Patent number: 9739425
    Abstract: Disclosed is a water manifold that provides a sturdy platform for both distributing water to various other locations or nodes and providing a support platform for a yard hydrant. The manifold is constructed of plastic and will not corrode. Further, the manifold is sturdy and provides a sufficiently large surface area to prevent sinking or tilting of the yard hydrant.

  • Patent number: 7234479
    Abstract: A water hydrant for suppling potable water from a water source has an internal movable riser contained within a housing that extends beneath the ground to a depth below which freezing temperatures cannot reach. A chamber housing located at a distal end of the hydrant, beneath the frost line, contains a valve which may be actuated by the moving riser to provide a flow of water from the water source and through the riser. The chamber housing is configured to receive residual water from the riser when the flow of water has been shut off by the valve and to store the water beneath the frost line under sanitary conditions. A piston is disposed on a distal end of the riser, is slidably disposed within the chamber housing, and moves with the riser to expel water from the chamber housing when a handle of the hydrant is subsequently moved to reopen the valve.

  • Patent number: 6899120
    Abstract: A yard hydrant has an elongated wet pipe with a plunger that seals against the inside of a well casing. Lifting a pivoting handle at the top of the wet pipe lowers the wet pipe which opens a normally closed supply valve. Pressurized water can then flow up the wet pipe and out of a nozzle head mounted to the upper end of the wet pipe. Lowering the handle pulls the wet pipe upward, thereby clearing it from the supply valve which is spring biased to shut off the water supply. The handle has a cam that positively actuates a normally closed anti-siphon valve so that water left in the wet pipe can fall under gravity to a collection chamber within the well casing beneath the piston. Lifting the handle again lowers the wet pipe and forces the water in the collection chamber back up the wet pipe. At the same time, the anti-siphon valve will close and the wet pipe re-opens the supply valve.

  • Patent number: 6047723
    Abstract: A yard hydrant comprising a cylinder, and a piston movable up and down in the cylinder in association with water flow into and out of a reservoir in the cylinder; tubular structure associated with the piston and extending upwardly from the piston and downwardly from the piston, and movable therewith; supply structure to deliver water from a source into the tubular structure for flow upwardly therein and delivery above the piston and cylinder when the piston is in a first position relative to the cylinder; there being porting carried by the tubular structure to drain water into the reservoir within the cylinder below the piston, when the piston is moved to a second position relative to the cylinder; and an actuator above the piston and cylinder to effect displacement of the piston and between up and down positions.

  • Patent number: 5261441
    Abstract: A yard hydrant includes a discharge nozzle above ground level connected to other vertically reciprocal working parts in the ground below the frost line. A cylindrical water reservoir unit, disposed below the frost line around said working parts, includes a diaphragm assembly removably attached to such working parts for reciprocation therewith, and a deformable diaphragm on said assembly provides a water storage area. Residual water in the hydrant when it is turned off is collected in the storage area and returned to the hydrant for discharge through the nozzle when the hydrant is turned on. The working parts are removable from the diaphragm assembly for servicing and repairs.
